OBCS stands for the Ontology of Biological and Clinical Statistics. OBCS is an ontology in the domain of biological and clinical statistics. It is aligned with the Basic Formal Ontology (BFO) and the Ontology for Biomedical Investigations (OBI). OBCS imports all possible biostatistics terms in OBI and includes many additional biostatistics terms, some of which were proposed and discussed in the OBI face-to-face workshop in Ann Arbor in 2012.

definition
The official definition, explaining the meaning of a class or property. Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions.

Barry Smith
The official OBI definition, explaining the meaning of a class or property: 'Shall be Aristotelian, formalized and normalized. Can be augmented with colloquial definitions' is terrible.
Can you fix to something like:
A statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property.
Alan Ruttenberg
Your proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can't be evaluated by those criteria.
On the specifics of the proposed definition:
We don't have definitions of 'meaning' or 'expression' or 'property'. For 'reference' in the intended sense I think we use the term 'denotation'. For 'expression', I think we you mean symbol, or identifier. For 'meaning' it differs for class and property. For class we want documentation that let's the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let's the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The 'intended reader' part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition.
Personally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable.
We also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.

x is preceded by y if and only if the time point at which y ends is before or equivalent to the time point at which x starts. Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point.
An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other.

This document is about information artifacts and their representations
A (currently) primitive relation that relates an information artifact to an entity.
7/6/2009 Alan Ruttenberg. Following discussion with Jonathan Rees, and introduction of "mentions" relation. Weaken the is_about relationship to be primitive.
We will try to build it back up by elaborating the various subproperties that are more precisely defined.
Some currently missing phenomena that should be considered "about" are predications - "The only person who knows the answer is sitting beside me" , Allegory, Satire, and other literary forms that can be topical without explicitly mentioning the topic.

A person's name denotes the person. A variable name in a computer program denotes some piece of memory. Lexically equivalent strings can denote different things, for instance "Alan" can denote different people. In each case of use, there is a case of the denotation relation obtaining, between "Alan" and the person that is being named.
A primitive, instance-level, relation obtaining between an information content entity and some portion of reality. Denotation is what happens when someone creates an information content entity E in order to specifically refer to something. The only relation between E and the thing is that E can be used to 'pick out' the thing. This relation connects those two together. Freedictionary.com sense 3: To signify directly; refer to specifically
2009-11-10 Alan Ruttenberg. Old definition said the following to emphasize the generic nature of this relation. We no longer have 'specifically denotes', which would have been primitive, so make this relation primitive.
g denotes r =def
r is a portion of reality

denotes
m is a quality measurement of q at t. When q is a quality, there is a measurement process p that has specified output m, a measurement datum, that is about q
8/6/2009 Alan Ruttenberg: The strategy is to be rather specific with this relationship. There are other kinds of measurements that are not of qualities, such as those that measure time. We will add these as separate properties for the moment and see about generalizing later
From the second IAO workshop [Alan Ruttenberg 8/6/2009: not completely current, though bringing in comparison is probably important]
This one is the one we are struggling with at the moment. The issue is what a measurement measures. On the one hand saying that it measures the quality would include it "measuring" the bearer = referring to the bearer in the measurement. However this makes comparisons of two different things not possible. On the other hand not having it inhere in the bearer, on the face of it, breaks the audit trail.
Werner suggests a solution based on "Magnitudes" a proposal for which we are awaiting details.
--
From the second IAO workshop, various comments, [commented on by Alan Ruttenberg 8/6/2009]
unit of measure is a quality, e.g. the length of a ruler.
[We decided to hedge on what units of measure are, instead talking about measurement unit labels, which are the information content entities that are about whatever measurement units are. For IAO we need that information entity in any case. See the term measurement unit label]
[Some struggling with the various subflavors of is_about. We subsequently removed the relation represents, and describes until and only when we have a better theory]
a represents b means either a denotes b or a describes
describe:
a describes b means a is about b and a allows an inference of at least one quality of b
We have had a long discussion about denotes versus describes.
From the second IAO workshop: An attempt at tieing the quality to the measurement datum more carefully.
a is a magnitude means a is a determinate quality particular inhering in some bearer b existing at a time t that can be represented/denoted by an information content entity e that has parts denoting a unit of measure, a number, and b. The unit of measure is an instance of the determinable quality.
From the second meeting on IAO:
An attempt at defining assay using Barry's "reliability" wording
assay:
process and has_input some material entity
and has_output some information content entity
and which is such that instances of this process type reliably generate
outputs that describes the input.
This one is the one we are struggling with at the moment. The issue is what a measurement measures. On the one hand saying that it measures the quality would include it "measuring" the bearer = referring to the bearer in the measurement. However this makes comparisons of two different things not possible. On the other hand not having it inhere in the bearer, on the face of it, breaks the audit trail.
Werner suggests a solution based on "Magnitudes" a proposal for which we are awaiting details.

a relation between a specifically dependent continuant (the characteristic) and any other entity (the bearer), in which the characteristic depends on the bearer for its existence.
inheres_in
Note that this relation was previously called "inheres in", but was changed to be called "characteristic of" because BFO2 uses "inheres in" in a more restricted fashion. This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing.

Location as a relation between instances: The primitive instance-level relation c located_in r at t reflects the fact that each continuant is at any given time associated with exactly one spatial region, namely its exact location. Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1. Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus

BFO 2 Reference: In all areas of empirical inquiry we encounter general terms of two sorts. First are general terms which refer to universals or types:animaltuberculosissurgical procedurediseaseSecond, are general terms used to refer to groups of entities which instantiate a given universal but do not correspond to the extension of any subuniversal of that universal because there is nothing intrinsic to the entities in question by virtue of which they – and only they – are counted as belonging to the given group. Examples are: animal purchased by the Emperortuberculosis diagnosed on a Wednesdaysurgical procedure performed on a patient from Stockholmperson identified as candidate for clinical trial #2056-555person who is signatory of Form 656-PPVpainting by Leonardo da VinciSuch terms, which represent what are called ‘specializations’ in [81
Entity doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example Werner Ceusters 'portions of reality' include 4 sorts, entities (as BFO construes them), universals, configurations, and relations. It is an open question as to whether entities as construed in BFO will at some point also include these other portions of reality. See, for example, 'How to track absolutely everything' at http://www.referent-tracking.com/_RTU/papers/CeustersICbookRevised.pdf

An entity that exists in full at any time in which it exists at all, persists through time while maintaining its identity and has no temporal parts.
BFO 2 Reference: Continuant entities are entities which can be sliced to yield parts only along the spatial dimension, yielding for example the parts of your table which we call its legs, its top, its nails. ‘My desk stretches from the window to the door. It has spatial parts, and can be sliced (in space) in two. With respect to time, however, a thing is a continuant.’ [60, p. 240
Continuant doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. For example, in an expansion involving bringing in some of Ceuster's other portions of reality, questions are raised as to whether universals are continuants

if b is a continuant and if, for some t, cis continuant_part of b at t, then c is a continuant. (axiom label in BFO2 Reference: [009-002])

occurrent
Occurrent
An entity that has temporal parts and that happens, unfolds or develops through time.
BFO 2 Reference: every occurrent that is not a temporal or spatiotemporal region is s-dependent on some independent continuant that is not a spatial region
BFO 2 Reference: s-dependence obtains between every process and its participants in the sense that, as a matter of necessity, this process could not have existed unless these or those participants existed also. A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players.
Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process.
Simons uses different terminology for relations of occurrents to regions: Denote the spatio-temporal location of a given occurrent e by 'spn[e]' and call this region its span. We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame.
An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region.

p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t. (axiom label in BFO2 Reference: [083-003])
BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay. Clear examples of boundaries of processes are almost always of the fiat sort (midnight, a time of death as declared in an operating theater or on a death certificate, the initiation of a state of war)

By using role terms in definitions, we can create a BFO conformant treatment of such entities drawing on the fact that, while an instance of professor may be simultaneously an instance of trade union member, no instance of the type professor role is also (at any time) an instance of the type trade union member role (any more than any instance of the type color is at any time an instance of the type length).If an ontology of employment positions should be defined in terms of roles following the above pattern, this enables the ontology to do justice to the fact that individuals instantiate the corresponding universals – professor, sergeant, nurse – only during certain phases in their lives.
b is a role means: b is a realizable entity & b exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be& b is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed.

or with divisions drawn by cognitive subjects for practical reasons, such as the division of a cake (before slicing) into (what will become) slices (and thus member parts of an object aggregate). However, this does not mean that fiat object parts are dependent for their existence on divisions or delineations effected by cognitive subjects. If, for example, it is correct to conceive geological layers of the Earth as fiat object parts of the Earth, then even though these layers were first delineated in recent times, still existed long before such delineation and what holds of these layers (for example that the oldest layers are also the lowest layers) did not begin to hold because of our acts of delineation.Treatment of material entity in BFOExamples viewed by some as problematic cases for the trichotomy of fiat object part, object, and object aggregate include: a mussel on (and attached to) a rock, a slime mold, a pizza, a cloud, a galaxy, a railway train with engine and multiple carriages, a clonal stand of quaking aspen, a bacterial community (biofilm), a broken femur. Note that, as Aristotle already clearly recognized, such problematic cases – which lie at or near the penumbra of instances defined by the categories in question – need not invalidate these categories. The existence of grey objects does not prove that there are not objects which are black and objects which are white; the existence of mules does not prove that there are not objects which are donkeys and objects which are horses. It does, however, show that the examples in question need to be addressed carefully in order to show how they can be fitted into the proposed scheme, for example by recognizing additional subdivisions [29

BFO 2 Reference: BFO rests on the presupposition that at multiple micro-, meso- and macroscopic scales reality exhibits certain stable, spatially separated or separable material units, combined or combinable into aggregates of various sorts (for example organisms into what are called ‘populations’). Such units play a central role in almost all domains of natural science from particle physics to cosmology. Many scientific laws govern the units in question, employing general terms (such as ‘molecule’ or ‘planet’) referring to the types and subtypes of units, and also to the types and subtypes of the processes through which such units develop and interact. The division of reality into such natural units is at the heart of biological science, as also is the fact that these units may form higher-level units (as cells form multicellular organisms) and that they may also form aggregates of units, for example as cells form portions of tissue and organs form families, herds, breeds, species, and so on. At the same time, the division of certain portions of reality into engineered units (manufactured artifacts) is the basis of modern industrial technology, which rests on the distributed mass production of engineered parts through division of labor and on their assembly into larger, compound units such as cars and laptops. The division of portions of reality into units is one starting point for the phenomenon of counting.
BFO 2 Reference: Each object is such that there are entities of which we can assert unproblematically that they lie in its interior, and other entities of which we can assert unproblematically that they lie in its exterior. This may not be so for entities lying at or near the boundary between the interior and exterior. This means that two objects – for example the two cells depicted in Figure 3 – may be such that there are material entities crossing their boundaries which belong determinately to neither cell. Something similar obtains in certain cases of conjoined twins (see below).
BFO 2 Reference: To say that b is causally unified means: b is a material entity which is such that its material parts are tied together in such a way that, in environments typical for entities of the type in question,if c, a continuant part of b that is in the interior of b at t, is larger than a certain threshold size (which will be determined differently from case to case, depending on factors such as porosity of external cover) and is moved in space to be at t at a location on the exterior of the spatial region that had been occupied by b at t, then either b’s other parts will be moved in coordinated fashion or b will be damaged (be affected, for example, by breakage or tearing) in the interval between t and t.causal changes in one part of b can have consequences for other parts of b without the mediation of any entity that lies on the exterior of b. Material entities with no proper material parts would satisfy these conditions trivially. Candidate examples of types of causal unity for material entities of more complex sorts are as follows (this is not intended to be an exhaustive list):CU1: Causal unity via physical coveringHere the parts in the interior of the unified entity are combined together causally through a common membrane or other physical covering\. The latter points outwards toward and may serve a protective function in relation to what lies on the exterior of the entity [13, 47

A function is a disposition that exists in virtue of the bearer’s physical make-up and this physical make-up is something the bearer possesses because it came into being, either through evolution (in the case of natural biological entities) or through intentional design (in the case of artifacts), in order to realize processes of a certain sort.

BFO 2 Reference: Object, Fiat Object Part and Object Aggregate are not intended to be exhaustive of Material Entity. Users are invited to propose new subcategories of Material Entity.
BFO 2 Reference: ‘Matter’ is intended to encompass both mass and energy (we will address the ontological treatment of portions of energy in a later version of BFO). A portion of matter is anything that includes elementary particles among its proper or improper parts: quarks and leptons, including electrons, as the smallest particles thus far discovered; baryons (including protons and neutrons) at a higher level of granularity; atoms and molecules at still higher levels, forming the cells, organs, organisms and other material entities studied by biologists, the portions of rock studied by geologists, the fossils studied by paleontologists, and so on.Material entities are three-dimensional entities (entities extended in three spatial dimensions), as contrasted with the processes in which they participate, which are four-dimensional entities (entities extended also along the dimension of time).According to the FMA, material entities may have immaterial entities as parts – including the entities identified below as sites; for example the interior (or ‘lumen’) of your small intestine is a part of your body. BFO 2.0 embodies a decision to follow the FMA here.

b is a continuant fiat boundary = Def. b is an immaterial entity that is of zero, one or two dimensions and does not include a spatial region as part. (axiom label in BFO2 Reference: [029-001])
BFO 2 Reference: In BFO 1.1 the assumption was made that the external surface of a material entity such as a cell could be treated as if it were a boundary in the mathematical sense. The new document propounds the view that when we talk about external surfaces of material objects in this way then we are talking about something fiat. To be dealt with in a future version: fiat boundaries at different levels of granularity.More generally, the focus in discussion of boundaries in BFO 2.0 is now on fiat boundaries, which means: boundaries for which there is no assumption that they coincide with physical discontinuities. The ontology of boundaries becomes more closely allied with the ontology of regions.
BFO 2 Reference: a continuant fiat boundary is a boundary of some material entity (for example: the plane separating the Northern and Southern hemispheres; the North Pole), or it is a boundary of some immaterial entity (for example of some portion of airspace). Three basic kinds of continuant fiat boundary can be distinguished (together with various combination kinds [29
Continuant fiat boundary doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites.

process-profile
ProcessProfile
On a somewhat higher level of complexity are what we shall call rate process profiles, which are the targets of selective abstraction focused not on determinate quality magnitudes plotted over time, but rather on certain ratios between these magnitudes and elapsed times. A speed process profile, for example, is represented by a graph plotting against time the ratio of distance covered per unit of time. Since rates may change, and since such changes, too, may have rates of change, we have to deal here with a hierarchy of process profile universals at successive levels
One important sub-family of rate process profiles is illustrated by the beat or frequency profiles of cyclical processes, illustrated by the 60 beats per minute beating process of John’s heart, or the 120 beats per minute drumming process involved in one of John’s performances in a rock band, and so on. Each such process includes what we shall call a beat process profile instance as part, a subtype of rate process profile in which the salient ratio is not distance covered but rather number of beat cycles per unit of time. Each beat process profile instance instantiates the determinable universal beat process profile. But it also instantiates multiple more specialized universals at lower levels of generality, selected from rate process profilebeat process profileregular beat process profile3 bpm beat process profile4 bpm beat process profileirregular beat process profileincreasing beat process profileand so on.In the case of a regular beat process profile, a rate can be assigned in the simplest possible fashion by dividing the number of cycles by the length of the temporal region occupied by the beating process profile as a whole. Irregular process profiles of this sort, for example as identified in the clinic, or in the readings on an aircraft instrument panel, are often of diagnostic significance.
The simplest type of process profiles are what we shall call ‘quality process profiles’, which are the process profiles which serve as the foci of the sort of selective abstraction that is involved when measurements are made of changes in single qualities, as illustrated, for example, by process profiles of mass, temperature, aortic pressure, and so on.

The definition of cell is intended to represent all cells, and thus a cell is defined as a material entity and not an anatomical structure, which implies that it is part of an organism (or the entirety of one).
cell
A cell in vitro that is or has been maintained or propagated as part of a cell culture.
MESH:D002478
Note that this class was re-labeled to 'cultured cell' instead of 'cell line cell', as it intent was clarified to cover any cultured cells of multicellular and unicellular organisms. This includes cells actively being cultured, or cells that have been cultured but are stored in a quiescent state for future use. In having been cultured, cells must establish homeostasis and often replicate in a foreign environment. Accomodation of this stress initiates a selection of cells fit for such challenges, wherein necessary adaptive biochemical and.or genetic changes can occur. These changes can set them apart from the in vivo cells from which they derive, and such changes will typically accumulate and change over increasing time in culture.
cultured cell
A cell in vitro that has undergone physical changes as a consequence of a deliberate and specific experimental procedure.
This class has been re-labeled to imply reference only to in vitro experimentally modified cells, similarly, the definition has been slightly updated to reflect this. 'experimentally modified cell' refers only to cells in vitro, and not modified in vivo/in environment cells. There is currently no class representing unmodified in vitro cells (other than the parent 'cell in vitro'), or a class representing modified native cells. More granular subclassing of experimentally modified cell can be found in ReO. MHB 1.12.12
experimentally modified cell in vitro
A cell that is maintained or propagated in a controlled artificial environment for use in an investigation.

'In vitro', translating literally to 'in glass', typically refers to a controlled, often sterile, laboratory setting where cells or other specimens are placed by some agent for the purpose of studying or manipulating them as part of some research investigation. 'In vitro' is intended to contrast with 'native',which refers to cells or other biological entities that are found in a natural setting. It describes unicellular organisms removed from a natural environement and multicellular organism cells removed from an organism, or cells derived in culture from such displaced cells.

DNA methylation
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence.

biological_process
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus.

objective specification
In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction.
A directive information entity that describes an intended process endpoint. When part of a plan specification the concretization is realized in a planned process in which the bearer tries to effect the world so that the process endpoint is achieved.
2009-03-16: original definition when imported from OBI read: "objective is an non realizable information entity which can serve as that proper part of a plan towards which the realization of the plan is directed."
2014-03-31: In the example of usage ("In the protocol of a ChIP assay the objective specification says to identify protein and DNA interaction") there is a protocol which is the ChIP assay protocol. In addition to being concretized on paper, the protocol can be concretized as a realizable entity, such as a plan that inheres in a person. The objective specification is the part that says that some protein and DNA interactions are identified. This is a specification of a process endpoint: the boundary in the process before which they are not identified and after which they are. During the realization of the plan, the goal is to get to the point of having the interactions, and participants in the realization of the plan try to do that.

data item
Data items include counts of things, analyte concentrations, and statistical summaries.
An information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method which reliably tends to produce (approximately) truthful statements.
2/2/2009 Alan and Bjoern discussing FACS run output data. This is a data item because it is about the cell population. Each element records an event and is typically further composed a set of measurment data items that record the fluorescent intensity stimulated by one of the lasers.
2009-03-16: data item deliberatly ambiguous: we merged data set and datum to be one entity, not knowing how to define singular versus plural. So data item is more general than datum.
2009-03-16: removed datum as alternative term as datum specifically refers to singular form, and is thus not an exact synonym.

A scalar measurement datum is a measurement datum that is composed of two parts, numerals and a unit label.
2009-03-16: we decided to keep datum singular in scalar measurement datum, as in
this case we explicitly refer to the singular form
Would write this as: has_part some 'measurement unit label' and has_part some numeral and has_part exactly 2, except for the fact that this won't let us take advantage of OWL reasoning over the numbers. Instead use has measurment value property to represent the same. Use has measurement unit label (subproperty of has_part) so we can easily say that there is only one of them.

scalar measurement datum
An information content entity whose concretizations indicate to their bearer how to realize them in a process.
2009-03-16: provenance: a term realizable information entity was proposed for OBI (OBI_0000337) , edited by the PlanAndPlannedProcess branch. Original definition was "is the specification of a process that can be concretized and realized by an actor" with alternative term "instruction".It has been subsequently moved to IAO where the objective for which the original term was defined was satisfied with the definitionof this, different, term.
2013-05-30 Alan Ruttenberg: What differentiates a directive information entity from an information concretization is that it can have concretizations that are either qualities or realizable entities. The concretizations that are realizable entities are created when an individual chooses to take up the direction, i.e. has the intention to (try to) realize it.
8/6/2009 Alan Ruttenberg: Changed label from "information entity about a realizable" after discussions at ICBO
Werner pushed back on calling it realizable information entity as it isn't realizable. However this name isn't right either. An example would be a recipe. The realizable entity would be a plan, but the information entity isn't about the plan, it, once concretized, *is* the plan. -Alan

MC, 2009-09-14 (following IAO call 2009-09-01): textual entities live at the FRBR (http://en.wikipedia.org/wiki/Functional_Requirements_for_Bibliographic_Records) manifestation level. Everything is significant: line break, pdf and html versions of same document are different textual entities.

ontology module
I have placed this under 'data about an ontology part', but this can be discussed. I think this is OK if 'part' is interpreted reflexively, as an ontology module is the whole ontology rather than part of it.
ontology file
This class and it's subclasses are applied to OWL ontologies. Using an rdf:type triple will result in problems with OWL-DL. I propose that dcterms:type is instead used to connect an ontology URI with a class from this hierarchy. The class hierarchy is not disjoint, so multiple assertions can be made about a single ontology.

obo basic subset ontology module
A subset ontology that is designed for basic applications to continue to make certain simplifying assumptions; many of these simplifying assumptions were based on the initial version of the Gene Ontology, and have become enshrined in many popular and useful tools such as term enrichment tools.
Examples of such assumptions include: traversing the ontology graph ignoring relationship types using a naive algorithm will not lead to cycles (i.e. the ontology is a DAG); every referenced term is declared in the ontology (i.e. there are no dangling clauses).
An ontology is OBO Basic if and only if it has the following characteristics:
DAG
Unidirectional
No Dangling Clauses
Fully Asserted
Fully Labeled
No equivalence axioms
Singly labeled edges
No qualifier lists
No disjointness axioms
No owl-axioms header

A quantitative confidence value that refers to an interval give values within which there is a high probability (95 percent by convention) that the true population value can be found. The calculation of a confidence interval considers the standard deviation of the data and the number of observations. Thus, a confidence interval narrows as the number of observations increases, or its variance (dispersion) decreases.

Beta Cell Biology Consortium
Extraction of Differential Gene Expression software
A software that can be used to produce lists of differentially expressed genes with confidence measures attached. These lists are generated via a False Discovery Rate (FDR) method of controlling the false positives. Patterns from Gene Expression (PaGE) is more than a differential expression analysis tool. PaGE is a tool to attach descriptive, dependable, and easily interpretable expression patterns to genes across multiple conditions, each represented by a set of replicated array experiments.
The input consists of (replicated) intensities from a collection of array experiments from two or more conditions (or from a collection of direct comparisons on 2-channel arrays). The output consists of patterns, one for each row identifier in the data file. One condition is used as a reference to which the other types are compared. The length of a pattern equals the number of non-reference sample types. The symbols in the patterns are integers, where positive integers represent up-regulation as compared to the reference sample type and negative integers represent down-regulation. The patterns are based on the false discovery rates for each position in the pattern, so that the number of positive and negative symbols that appear in each position of the pattern is as descriptive as the data variability allows. The patterns generated are easily interpretable in that integers are used to represent different levels of up- or down-regulation as compared to the reference sample type.

Traditionally, sensitivity inheres in a population of material entity like human. However, it raises a concern in the existance of such sensitivity disposition in the context of machine learning using syntheti data generated with mathematical formula. In this case, the population of disposition bearer are not population of organisms or material entities. Here the bearer of the disposition is not independent continuant.

Equations aimed to assess how the quantified uncertainties in model inputs propagate in model calculations to produce and uncertainty range in a given model outcome of interest.In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them. When the variables are the values of experimental measurements they have uncertainties due to measurement limitations (e.g., instrument precision) which propagate due to the combination of variables in the function.

Legal uncertainty is relevant "wherever agents must consider future contingencies of personal liability for their actions (or inactions)". High legal uncertainty can result in defensive responses in regard to both decision making and release of information. Legal uncertainty may also play a role where actions are conditioned on the clarity or otherwise of a legal framework in allowing one to predict the consequences of particular actions.

Moral uncertainty stems from the underlying moral issues related to action and inaction in any given case. De Marchi notes that, though similar to legal responsibility, moral guilt may occur absent legal responsibility when negative consequences might have been limited by the dissemination of prior information or more effective management for example. "Moral uncertainty is linked to the ethical tradition of a given country be it or not enacted in legislation (juridical and societal norms, shared moral values, mores), as well as the psychological characteristics of persons in charge, their social status and professional roles" (De Marchi, 1994). Moral uncertainty would typically be high when moral and ethical dimensions of an issue are central and participants have a range of understandings of the moral imperatives at stake.

Communities from one region to another may differ in the set of norms, values, and manner of relating characteristic of their societies. This in turn can result in differences in approach to decision making and assessment. Some salient characteristics of these differences will be different views about the role of consensus versus conflict, on locating responsibility between individuals and larger groups, on views about the legitimacy and role of social and private institutions, and on attitudes to authority and expertise. From De Marchi (1994). Societal uncertainty would typically be high when decisions involve substantial collaboration among groups characterized by divergent decision making styles.

Institutional uncertainty is in some sense a subset of societal uncertainty, and refers more specifically to the role and actions of institutions and their members. Institutional uncertainty stems from the "diverse cultures and traditions, divergent missions and values, different structures, and work styles among personnel of different agencies" (De Marchi, 1994). High institutional uncertainty can hinder collaboration or understanding among agencies, and can make the actions of institutions difficult to predict.

Proprietary uncertainty occurs due to the fact that information and knowledge about an issue are not uniformly shared among all those who could potentially use it. That is, some people or groups have information that others don't and may assert ownership or control over it. "Proprietary uncertainty becomes most salient when it is necessary to reconcile the general needs for safety, health, and environment protection with more sectorial needs pertaining, for instance, to industrial production and process, or to licensing and control procedures" (De Marchi, 1994). De Marchi notes that 'whistle blowing' is another source of proprietary uncertainty in that there is a need for protection of those who act in sharing information for the public good. Proprietary uncertainty would typically be high when knowledge plays a key role in assessment, but is not widely shared among participants. An example of such would be the case of external safety of military nuclear production facilities.

Situational uncertainty relates to "the predicament of the person responsible for a crisis, either in the phase of preparation and planning, or of actual emergency. It refers to individual behaviours or personal interventions in crisis situations" (De Marchi, 1994) and as such represents a form of integration over the other six types of uncertainty. That is, it tends to combine the uncertainties one has to face in a given situation or on a particular issue. High situational uncertainty would be characterized by situations where individual decisions play a substantial role and there is uncertainty about the nature of those decisions.

A belief is psychologically certain when the subject who has it is supremely convinced of its truth. Certainty in this sense is similar to incorrigibility, which is the property a belief has of being such that the subject is incapable of giving it up. But psychological certainty is not the same thing as incorrigibility. A belief can be certain in this sense without being incorrigible; this may happen, for example, when the subject receives a very compelling bit of counterevidence to the (previously) certain belief and gives it up for that reason. Moreover, a belief can be incorrigible without being psychologically certain. For example, a mother may be incapable of giving up the belief that her son did not commit a gruesome murder, and yet, compatible with that inextinguishable belief, she may be tortured by doubt.

fluorescent reporter intensity
A measurement datum that represents the output of a scanner measuring the intensity value for each fluorescent reporter.
person:Chris Stoeckert
group:OBI
From the DT branch: This term and definition were originally submitted by the community to our branch, but we thought they best fit DENRIE. However we see several issues with this. First of all the name 'probe' might not be used in OBI. Instead we have a 'reporter' role. Also, albeit the term 'probe intensity' is often used in communities such as the microarray one, the name 'probe' is ambiguous (some use it to refer to what's on the array, some use it to refer to what's hybed to the array). Furthermore, this concept could possibly be encompassed by combining different OBI terms, such as the roles of analyte, detector and reporter (you need something hybed to a probe on the array to get an intensity) and maybe a more general term for 'measuring intensities'. We need to find the right balance between what is consistent with OBI and combinations of its terms and what is user-friendly. Finally, note that 'intensity' is already in the OBI .owl file and is also in PATO. Why didn't OBI import it from PATO? This might be a problem.

planned process
planned process
Injecting mice with a vaccine in order to test its efficacy
A process that realizes a plan which is the concretization of a plan specification.
'Plan' includes a future direction sense. That can be problematic if plans are changed during their execution. There are however implicit contingencies for protocols that an agent has in his mind that can be considered part of the plan, even if the agent didn't have them in mind before. Therefore, a planned process can diverge from what the agent would have said the plan was before executing it, by adjusting to problems encountered during execution (e.g. choosing another reagent with equivalent properties, if the originally planned one has run out.)
We are only considering successfully completed planned processes. A plan may be modified, and details added during execution. For a given planned process, the associated realized plan specification is the one encompassing all changes made during execution. This means that all processes in which an agent acts towards achieving some
objectives is a planned process.

evaluant role
When a specimen of blood is assayed for glucose concentration, the blood has the evaluant role. When measuring the mass of a mouse, the evaluant is the mouse. When measuring the time of DNA replication, the evaluant is the DNA. When measuring the intensity of light on a surface, the evaluant is the light source.

A role inhering in a biological or chemical entity that is intended to be applied in a scientific technique to participate (or have molecular components that participate) in a chemical reaction that facilitates the generation of data about some entity distinct from the bearer, or the generation of some specified material output distinct from the bearer.

PERSON:Matthew Brush
Feb 10, 2009. changes after discussion at OBI Consortium Workshop Feb 2-6, 2009. accepted as core term.
May 28 2013. Updated definition taken from ReO based on discussions initiated in Philly 2011 workshop. Former defnition described a narrower view of reagents in chemistry that restricts bearers of the role to be chemical entities ("a role played by a molecular entity used to produce a chemical reaction to detect, measure, or produce other substances"). Updated definition allows for broader view of reagents in the domain of biomedical research to include larger materials that have parts that participate chemically in a molecular reaction or interaction.
(copied from ReO)
Reagents are distinguished from instruments or devices that also participate in scientific techniques by the fact that reagents are chemical or biological in nature and necessarily participate in or have parts that participate in some chemical interaction or reaction during their intended participation in some technique. By contrast, instruments do not participate in a chemical reaction/interaction during the technique.
Reagents are distinguished from study subjects/evaluants in that study subjects and evaluants are that about which conclusions are drawn and knowledge is sought in an investigation - while reagents, by definition, are not. It should be noted, however, that reagent and study subject/evaluant roles can be borne by instances of the same type of material entity - but a given instance will realize only one of these roles in the execution of a given assay or technique. For example, taq polymerase can bear a reagent role or an evaluant role. In a DNA sequencing assay aimed at generating sequence data about some plasmid, the reagent role of the taq polymerase is realized. In an assay to evaluate the quality of the taq polymerase itself, the evaluant/study subject role of the taq is realized, but not the reagent role since the taq is the subject about which data is generated.
In regard to the statement that reagents are 'distinct' from the specified outputs of a technique, note that a reagent may be incorporated into a material output of a technique, as long as the IDENTITY of this output is distinct from that of the bearer of the reagent role. For example, dNTPs input into a PCR are reagents that become part of the material output of this technique, but this output has a new identity (ie that of a 'nucleic acid molecule') that is distinct from the identity of the dNTPs that comprise it. Similarly, a biotin molecule input into a cell labeling technique are reagents that become part of the specified output, but the identity of the output is that of some modified cell specimen which shares identity with the input unmodified cell specimen, and not with the biotin label. Thus, we see that an important criteria of 'reagent-ness' is that it is a facilitator, and not the primary focus of an investigation or material processing technique (ie not the specified subject/evaluant about which knowledge is sought, or the specified output material of the technique).

22Jun09. The definition includes whole organisms, and can include a human. The link between specimen role and study subject role has been removed. A specimen taken as part of a case study is not considered to be a population representative, while a specimen taken as representing a population, e.g. person taken from a cohort, blood specimen taken from an animal) would be considered a population representative and would also bear material sample role.
Note: definition is in specimen creation objective which is defined as an objective to obtain and store a material entity for potential use as an input during an investigation.
blood taken from animal: animal continues in study, whereas blood has role specimen.
something taken from study subject, leaves the study and becomes the specimen.

PMID: 18208636.Br J Nutr. 2008 Jan 22;:1-11.Effect of vitamin D supplementation on bone and vitamin D status among Pakistani immigrants in Denmark: a randomised double-blinded placebo-controlled intervention study.
An intervention design is a study design in which a controlled process applied to the subjects (the intervention) serves as the independent variable manipulated by the experimentalist. The treatment (perturbation or intervention) defined can be defined as a combination of values taken by independent variable manipulated by the experimentalists are applied to the recruited subjects assigned (possibly by applying specific methods) to treatment groups. The specificity of intervention design is the fact that independent variables are being manipulated and a response of the biological system is evaluated via response variables as monitored by possibly a series of assays.

independent variable specification
In a study in which gene expression is measured in patients between 8 month to 4 years old that have mild or severe malaria and in which the hypothesis is that gene expression in that age group is a function of disease status, disease status is the independent variable.
a directive information entity that is part of a study design. Independent variables are entities whose values are selected to determine its relationship to an observed phenomenon (the dependent variable). In such an experiment, an attempt is made to find evidence that the values of the independent variable determine the values of the dependent variable (that which is being measured). The independent variable can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given. The dependent variable on the other hand, usually cannot be directly controlled

device
A voltmeter is a measurement device which is intended to perform some measure function.
An autoclave is a device that sterlizes instruments or contaminated waste by applying high temperature and pressure.
A material entity that is designed to perform a function in a scientific investigation, but is not a reagent.
2012-12-17 JAO: In common lab usage, there is a distinction made between devices and reagents that is difficult to model. Therefore we have chosen to specifically exclude reagents from the definition of "device", and are enumerating the types of roles that a reagent can perform.
2013-6-5 MHB: The following clarifications are outcomes of the May 2013 Philly Workshop. Reagents are distinguished from devices that also participate in scientific techniques by the fact that reagents are chemical or biological in nature and necessarily participate in some chemical interaction or reaction during the realization of their experimental role. By contrast, devices do not participate in such chemical reactions/interactions. Note that there are cases where devices use reagent components during their operation, where the reagent-device distinction is less clear. For example:
(1) An HPLC machine is considered a device, but has a column that holds a stationary phase resin as an operational component. This resin qualifies as a device if it participates purely in size exclusion, but bears a reagent role that is realized in the running of a column if it interacts electrostatically or chemically with the evaluant. The container the resin is in (“the column”) considered alone is a device. So the entire column as well as the entire HPLC machine are devices that have a reagent as an operating part.
(2) A pH meter is a device, but its electrode component bears a reagent role in virtue of its interacting directly with the evaluant in execution of an assay.
(3) A gel running box is a device that has a metallic lead as a component that participates in a chemical reaction with the running buffer when a charge is passed through it. This metallic lead is considered to have a reagent role as a component of this device realized in the running of a gel.
In the examples above, a reagent is an operational component of a device, but the device itself does not realize a reagent role (as bearing a reagent role is not transitive across the part_of relation). In this way, the asserted disjointness between a reagent and device holds, as both roles are never realized in the same bearer during execution of an assay.

A measurement of an IC50 value under specific assay conditions approximates KD, namely the binding reaction is at an equilibrium, there is a single population of sites on the receptor that competitor and ligand are binding to, and the concentration of the receptor must be much less than the KD for the competitor and the ligand. In this case, according to Cheng and Prussoff, KD = IC50 / (1 + Lstot / KDs), in which Lstot is the total concentration of the labeled competitor and KDs is the KD value of that competitor.

random access memory
Random-access memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed directly in any random order. In contrast, other data storage media such as hard disks, CDs, DVDs and magnetic tape, as well as early primary memory types such as drum memory, read and write data only in a predetermined order, consecutively, because of mechanical design limitations. Therefore, the time to access a given data location varies significantly depending on its physical location

An information content entity that specifies a value within a classification scheme or on a quantitative scale.

A value specification of '20g' for a measurement data item of the mass of a particular mouse 'is about' the mass of that mouse.

"The genome coverage increased from 81.16% to 93.91%"
A data item that is the total number of bases in reads, divided by genome size, assumed to be the reference size (for instance of 3.10 Gb for human and 2.73 Gb for mouse) and refers to the percentage of the genome that is contained in the assembly based on size estimates; these are usually based on cytological techniques. Genome coverage of 90–95% is generally considered to be good, as most genomes contain a considerable fraction of repetitive regions that are difficult to sequence. So it is not a cause for concern if the genome coverage of an assembly is a bit less than 100%.

"Here, the contig and scaffold N50 of the YH genome were ~20.9 kbp and ~22 Mbp"
the weighted median item size or N50 is a weighted median of the lengths of items, equal to the length of the longest item i such that the sum of the lengths of items greater than or equal in length to i is greater than or equal to half the length of all of the items. With regard to assemblies the items are typically contigs or scaffolds. It therefore denotes the ability of the software to create contigs and provides information about the resulting sequence assembly

"Here, the contig and scaffold N50 of the YH genome were ~20.9 kbp and ~22 Mbp"
N50 statistic computed for the contigs produced by the assembly process. A contig N50 is calculated by first ordering every contig by length from longest to shortest. Next, starting from the longest contig, the lengths of each contig are summed, until this running sum equals one-half of the total length of all contigs in the assembly. The contig N50 of the assembly is the length of the shortest contig in this list.

The extent of a 'cultured cell population' is restricted only in that all cell members must share a propagation history (ie be derived through a common lineage of passages from an initial culture). In being defined in this way, this class can be used to refer to the populations that researchers actually use in the practice of science - ie are the inputs to culturing, experimentation, and sharing. The cells in such populations will be a relatively uniform population as they have experienced similar selective pressures due to their continuous co-propagation. And this population will also have a single passage number, again owing to their common passaging history. Cultured cell populations represent only a collection of cells (ie do not include media, culture dishes, etc), and include populations of cultured unicellular organisms or cultured multicellular organism cells. They can exist under active culture, stored in a quiescent state for future use, or applied experimentally.

logistic-log curve fitting
Typically used in an enzyme-linked immunosorbent assay (ELISA) to model the relationship between optical density (OD) and dilution. In this case a and d correspond to the theoretical OD of the assay at zero and infinite concentrations, respectively; c is the dilution associated with the point of symmetry of the sigmoid and is located at the midpoint of the assay found at the inflection point of the curve; b is a curvature parameter and is related to the slope of the curve.
A logistic-log curve fitting is a curve fitting where a curve of the form y=d+((a-d)/(1+(x/c)^b)) is obtained, where a, b, c, and d are determined so to optimize its fit to the input data points (x_1, y_1), (x_2, y_2), ..., (x_n, y_n).

Then a curve with equation log((y-y_0)/(y_infty-y))=a+b log(x) is obtained, where a and b are determined to optimize its fit to the input data points.
The above definition refers to the 'fully specified' logit-log model. The reduced form of this, when it is assumed that y_0=0, is named 'partially specified' logit-log model.

K-fold cross validation method
K-fold cross-validation randomly partitions the original sample into K subsamples. Of the K subsamples, a single subsample is retained as the validation data for testing the model, and the remaining K - 1 subsamples are used as training data. The cross-validation process is then repeated K times (the folds), with each of the K subsamples used exactly once as the validation data. The K results from the folds then can be averaged (or otherwise combined) to produce a single estimation. The advantage of this method over repeated random sub-sampling is that all observations are used for both training and validation, and each observation is used for validation exactly once. 10-fold cross-validation is commonly used

boostrapping
Although widely accepted that high throughput biological data are typically highly noisy, the effects that this uncertainty has upon the conclusions we draw from these data are often overlooked. However, in order to assign any degree of confidence to our conclusions, we must quantify these effects. Bootstrap resampling is one method by which this may be achieved.
Bootstrapping is a statistical method for estimating the sampling distribution of a statistic by sampling with replacement from the original data, most often with the purpose of deriving robust estimates of standard errors and confidence intervals of a population parameter like a mean, median, proportion, odds ratio, correlation coefficient or regression coefficient

A k-means clustering is a data transformation which achieves a class discovery or partitioning objective, which takes as input a collection of objects (represented as points in multidimensional space) and which partitions them into a specified number k of clusters. The algorithm attempts to find the centers of natural clusters in the data. The most common form of the algorithm starts by partitioning the input points into k initial sets, either at random or using some heuristic data. It then calculates the mean point, or centroid, of each set. It constructs a new partition by associating each point with the closest centroid. Then the centroids are recalculated for the new clusters, and the algorithm repeated by alternate applications of these two steps until convergence, which is obtained when the points no longer switch clusters (or alternatively centroids are no longer changed).

hierarchical clustering
A hierarchical clustering is a data transformation which achieves a class discovery objective, which takes as input data item and builds a hierarchy of clusters. The traditional representation of this hierarchy is a tree (visualized by a dendrogram), with the individual input objects at one end (leaves) and a single cluster containing every object at the other (root).

dye swap merge
A dye swap merge is a replicate analysis which takes as input data from paired two-channel microarray assays where the sample labeled with one dye in the first assay is labeled with the other dye in the second assay and vice versa. The output for each reporter is obtained by combining its (raw or possibly pre-processed) M values in the two assays, where the M value in an assay is defined as the difference of the log intensities in the two channels. This can be used as a normalization step, when appropriate assumptions are met.

submatrix extraction
When presented with the data from an expression microarray experiment in the form of a matrix, whose rows correspond to genes and whose columns correspond to samples, if one filters some of the genes and/or some of the samples out, the resulting data set corresponds to a submatrix of the original set.
A submatrix extraction is a projection whose input is a matrix and whose output is a matrix obtained by selecting certain rows and columns from the input. (Note that, if one represents the input matrix as a vector obtained by concatenating its rows, then extracting a submatrix is equivalent to projecting this vector into that composed by the entries belonging to the rows and columns of interest from the input matrix.)
Note that this can be considered as a special case of projection if one represents the input matrix as a vector obtained by concatenating its rows.

loess fitting
A loess fitting is a curve fitting obtained by localized regression. The latter refers to fitting a polynomial (straight line, quadratic, cubic, etc) to data values within a window covering a fraction of the total number of observations. As the window slides along the axis, a new polynomial is fit to the observations falling within the window. This continues until all points are fit with a local polynomial. The results are then smoothed together to form a curve. The smoothness of loess fits is controlled by a smoothing parameter (often denoted as alpha, usually between 1/4 and 1) and the degree of the polynomial that is fitted by the method (usually denoted by lambda).

MA transformation
MA transformations are typically used in microarray data analyses. In this context, the g_i and r_i represent the reporter intensities in the two channels of a 2-channel assay or the reporter intensities in two related one-channel assays. Typically the base used for the logarithm is 2.
An MA transformation is a data transformation which takes as input a collection of data points (g_1, r_1), (g_2, r_2), ..., (g_n, r_n) with the r_i and g_i positive real numbers, and whose output is the collection of data points (A_1, M_1), (A_2, M_2), ..., (A_n, M_n) where, for each i, A_i=(log(g_i)+log(r_i))/2 and M_i=log(r_i)-log(g_i). Here log denotes a logarithmic transformation.

PMID: 17601993-Objective: HIV-infected patients with lipodystrophy (HIV-lipodystrophy) are insulin resistant and have elevated plasma free fatty acid (FFA) concentrations. We aimed to explore the mechanisms underlying FFA-induced insulin resistance in patients with HIV-lipodystrophy. Research Design and Methods: Using a randomized placebo-controlled cross-over design, we studied the effects of an overnight acipimox-induced suppression of FFA on glucose and FFA metabolism by using stable isotope labelled tracer techniques during basal conditions and a two-stage euglycemic, hyperinsulinemic clamp (20 mU insulin/m(2)/min; 50 mU insulin/m(2)/min) in nine patients with nondiabetic HIV-lipodystrophy. All patients received antiretroviral therapy. Biopsies from the vastus lateralis muscle were obtained during each stage of the clamp. Results: Acipimox treatment reduced basal FFA rate of appearance by 68.9% (52.6%-79.5%) and decreased plasma FFA concentration by 51.6 % (42.0%-58.9%), (both, P < 0.0001). Endogenous glucose production was not influenced by acipimox. During the clamp the increase in glucose-uptake was significantly greater after acipimox treatment compared to placebo (acipimox: 26.85 (18.09-39.86) vs placebo: 20.30 (13.67-30.13) mumol/kg/min; P < 0.01). Insulin increased phosphorylation of Akt (Thr(308)) and GSK-3beta (Ser(9)), decreased phosphorylation of glycogen synthase (GS) site 3a+b and increased GS-activity (I-form) in skeletal muscle (P < 0.01). Acipimox decreased phosphorylation of GS (site 3a+b) (P < 0.02) and increased GS-activity (P < 0.01) in muscle. Conclusion: The present study provides direct evidence that suppression of lipolysis in patients with HIV-lipodystrophy improves insulin-stimulated peripheral glucose-uptake. The increased glucose-uptake may in part be explained by increased dephosphorylation of GS (site 3a+b) resulting in increased GS activity.

Using a randomised blocks& design, the subjects are assessed and put in blocks of four according to how severe their skin condition is; the four most severe cases are the first block, the next four most severe cases are the second block, and so on to the twentieth block. The four &members of each block are then randomly assigned, one to each of the four treatment groups. http://www.stats.gla.ac.uk/steps/glossary/anova.html#rbd))
A randomized complete block design is_a study design which assigns randomly treatments to block. The number of units per block equals the number of treatment so each block receives each treatment exactly once (hence the qualifier 'complete'). The design was originally devised from field trials used in agronomy and agriculture. The analysis assumes that there is no interaction between block and treatment. The method was then used in other settings So The randomised complete block design is a design in which the subjects are matched according to a variable which the experimenter wishes to control. The subjects are put into groups (blocks) of the same size as the number of treatments. The members of each block are then randomly assigned to different treatment groups.

PMID: 17582121-Our objective was to examine the effects of dietary cation-anion difference (DCAD) with different concentrations of dietary crude protein (CP) on performance and acid-base status in early lactation cows. Six lactating Holstein cows averaging 44 d in milk were used in a 6 x 6 Latin square design with a 2 x 3 factorial arrangement of treatments: DCAD of -3, 22, or 47 milliequivalents (Na + K - Cl - S)/100 g of dry matter (DM), and 16 or 19% CP on a DM basis. Linear increases with DCAD occurred in DM intake, milk fat percentage, 4% fat-corrected milk production, milk true protein, milk lactose, and milk solids-not-fat. Milk production itself was unaffected by DCAD. Jugular venous blood pH, base excess and HCO3(-) concentration, and urine pH increased, but jugular venous blood Cl- concentration, urine titratable acidity, and net acid excretion decreased linearly with increasing DCAD. An elevated ratio of coccygeal venous plasma essential AA to nonessential AA with increasing DCAD indicated that N metabolism in the rumen was affected, probably resulting in more microbial protein flowing to the small intestine. Cows fed 16% CP had lower urea N in milk than cows fed 19% CP; the same was true for urea N in coccygeal venous plasma and urine. Dry matter intake, milk production, milk composition, and acid-base status did not differ between the 16 and 19% CP treatments. It was concluded that DCAD affected DM intake and performance of dairy cows in early lactation. Feeding 16% dietary CP to cows in early lactation, compared with 19% CP, maintained lactation performance while reducing urea N excretion in milk and urine.
Latin square design is_a study design which allows in its simpler form controlling 2 levels of nuisance variables (also known as blocking variables).he 2 nuisance factors are divided into a tabular grid with the property that each row and each column receive each treatment exactly once.

PMID: 6846242-Beaton et al (Am J Clin Nutr 1979;32:2546-59) reported on the partitioning of variance in 1-day dietary data for the intake of energy, protein, total carbohydrate, total fat, classes of fatty acids, cholesterol, and alcohol. Using the same food intake data and the expanded National Heart, Lung and Blood Institute food composition data base, these analyses of sources of variance have been expanded to include classes of carbohydrate, vitamin A, vitamin C, thiamin, riboflavin, niacin, calcium, iron, total ash, caffeine, and crude fiber. The analyses relate to observed intakes (replicated six times) of 30 adult males and 30 adult females obtained under a paired Graeco-Latin square design with sequence of interview, interviewer, and day of the week as determinants. Neither sequence nor interviewer made consistent contribution to variance. In females, day of the week had a significant effect for several nutrients. The major partitioning of variance was between interindividual variation (between subjects) and intraindividual variation (within subjects) which included both true day-to-day variation in intake and methodological variation. For all except caffeine, the intraindividual variability of 1-day data was larger than the interindividual variability. For vitamin A, almost all of the variance was associated with day-to-day variability. One day data provide a very inadequate estimate of usual intake of individuals. In the design of nutrition studies it is critical that the intended use of dietary data be a major consideration in deciding on methodology. There is no ideal dietary method. There may be preferred methods for particular purposes.

PMID: 14744830-Microarrays are powerful tools for surveying the expression levels of many thousands of genes simultaneously. They belong to the new genomics technologies which have important applications in the biological, agricultural and pharmaceutical sciences. There are myriad sources of uncertainty in microarray experiments, and rigorous experimental design is essential for fully realizing the potential of these valuable resources. Two questions frequently asked by biologists on the brink of conducting cDNA or two-colour, spotted microarray experiments are 'Which mRNA samples should be competitively hybridized together on the same slide?' and 'How many times should each slide be replicated?' Early experience has shown that whilst the field of classical experimental design has much to offer this emerging multi-disciplinary area, new approaches which accommodate features specific to the microarray context are needed. In this paper, we propose optimal designs for factorial and time course experiments, which are special designs arising quite frequently in microarray experimentation. Our criterion for optimality is statistical efficiency based on a new notion of admissible designs; our approach enables efficient designs to be selected subject to the information available on the effects of most interest to biologists, the number of arrays available for the experiment, and other resource or practical constraints, including limitations on the amount of mRNA probe. We show that our designs are superior to both the popular reference designs, which are highly inefficient, and to designs incorporating all possible direct pairwise comparisons. Moreover, our proposed designs represent a substantial practical improvement over classical experimental designs which work in terms of standard interactions and main effects. The latter do not provide a basis for meaningful inference on the effects of most interest to biologists, nor make the most efficient use of valuable and limited resources.

A 'cell culture' as used here referes to a new lineage of cells in culture deriving from a single biological source.. New cultures are established through the initial isolation and culturing of cells from an organismal source, or through changes in an existing cell culture or line that result in a new culture with unique characteristics. This can occur through the passaging/selection of a primary culture into a secondary culture or line, or experimental modifications of an existing cell culture or line such as an immortalization process or other stable genetic modification. This class covers establishment of cultures of either multicellular organism cells or unicellular organisms.

Wilks' lambda distribution (named for Samuel S. Wilks), is a probability distribution used in multivariate hypothesis testing, especially with regard to the likelihood-ratio test and Multivariate analysis of variance. It is a multivariate generalization of the univariate F-distribution, and generalizes the F-distribution in the same way that the Hotelling's T-squared distribution generalizes Student's t-distribution.

[x̄(k)- x̄(1)]/(s/√n)
where random samples of size n have been taken from k independent and identically distributed normal populations, with x̄(1) and x̄(k) being, respectively, the smallest and largest of the k sample means, and s2 being the pooled estimate of the common variance. This statistic is particularly used in multiple comparison tests.

Multi-way anova is an analysis of variance where the difference groups being compared are associated to the factor levels of more than 2 independent variables. The null hypothesis is an absence of difference between the means calculated for each of the groups. The test assumes normality and equivariance of the data.
multiway ANOVA
A null hypothesis is a statistical hypothesis that is tested for possible rejection under the assumption that it is true (usually that observations are the result of chance). The concept was introduced by R. A. Fisher.
The hypothesis contrary to the null hypothesis, usually that the observations are the result of a real effect, is known as the alternative hypothesis.[wolfram alpha]

Cleveland dot plot is a dot plot which plots points that each belong to one of several categories. They are an alternative to bar charts or pie charts, and look somewhat like a horizontal bar chart where the bars are replaced by a dots at the values associated with each category. Compared to (vertical) bar charts and pie charts, Cleveland argues that dot plots allow more accurate interpretation of the graph by readers by making the labels easier to read, reducing non-data ink (or graph clutter) and supporting table look-up.which

the multinomial distribution is a probability distribution which gives the probability of any particular combination of numbers of successes for various categories defined in the context of n independent trials each of which leads to a success for exactly one of k categories, with each category having a given fixed success probability.
multinomial distribution
a Funnel plot is a scatter plot of treatment effect versus a measure of study size and aims to provide a visual aid to detecting bias or systematic heterogeneity. A symmetric inverted funnel shape arises from a ‘well-behaved’ data set, in which publication bias is unlikely. An asymmetric funnel indicates a relationship between treatment effect and study size.
Known caveats: If high precision studies really are different from low precision studies with respect to effect size (e.g., due to different populations examined) a funnel plot may give a wrong impression of publication bias. The appearance of the funnel plot can change quite dramatically depending on the scale on the y-axis — whether it is the inverse square error or the trial size.
Funnel plot was introduced by Light and Palmer in 1984.
Funnel plot
beanplot is a plot in which (one or) multiple batches ("beans") are shown. Each bean consists of a density trace, which is mirrored to
form a polygon shape. Next to that, a one-dimensional scatter plot shows all the individual measurements, like in a stripchart.
The name beanplot stems from green beans. The density shape can be seen as the pod of a green bean, while the scatter plot shows the seeds inside the pod.

Hotelling T squared distribution is a probability distribution used in multivariate hypothesis testing, which is a univariate distribution proportional to the F-distribution and arises importantly as the distribution of a set of statistics which are natural generalizations of the statistics underlying Student's t-distribution.
In particular, the distribution arises in multivariate statistics in undertaking tests of the differences between the (multivariate) means of different populations, where tests for univariate problems would make use of a t-test.
The distribution is named for Harold Hotelling, who developed it[1] as a generalization of Student's t-distribution.
This distribution is commonly used to describe the sample Mahalanobis distance between two populations.
Hotelling T2 distribution
The correlation coefficient of two variables in a data sample is their covariance divided by the product of their individual standard deviations. It is a normalized measurement of how the two are linearly related.

the geometric distribution is a negative binomial distribution where r is 1.
It is useful for modeling the runs of consecutive successes (or failures) in repeated independent trials of a system.
The geometric distribution models the number of successes before one failure in an independent succession of tests where each test results in success or failure.
The geometric distribution with prob = p has density
p(x) = p (1-p)^x
for x = 0, 1, 2, …, 0 < p ≤ 1.
If an element of x is not integer, the result of dgeom is zero, with a warning.
The quantile is defined as the smallest value x such that F(x) ≥ p, where F is the distribution function.

Lineweaver-Burk plot is a graph which is the graphical representation of the Lineweaver–Burk equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934. The plot provides a useful graphical method for analysis of the Michaelis–Menten equation.
It was widely used to determine important terms in enzymology and enzyme kinetics as the x-intercept of the graph represents −1/Km and the y-intercept of such a graph is equivalent to the inverse of Vmax

Spearman's rank correlation coefficient is a correlation coefficient which is a nonparametric measure of statistical dependence between two ranked variables. It assesses how well the relationship between two variables can be described using a monotonic function. If there are no repeated data values, a perfect Spearman correlation of +1 or −1 occurs when each of the variables is a perfect monotone function of the other.
Spearman's coefficient may be used when the conditions for computing Pearson's correlation are not met (e.g linearity, normality of the 2 continuous variables) but may require a ranking transformation of the variables

repeated measure ANOVA is a kind of ANOVA specifically developed for non-independent observations as found when repeated measurements on the sample experimental unit.
repeated measure ANOVA is sensitive to departure from normality (evaluation using Bartlett's test), more so in the case of unbalanced groups (i.e. different sizes of sample populations).
Departure from sphericity (evaluation using Mauchly'test) used to be an issue which is now handled robustly by modern tools such as R's lme4 or nlme, which accommodate dependence assumptions other than sphericity.

Galbraith (Radial) plot is a scatter plot which can be used in the meta-analytic context to examine the data for heterogeneity. For a fixed-effects model, the plot shows the inverse of the standard errors on the horizontal axis against the individual observed effect sizes or outcomes standardized by their corresponding standard errors on the vertical axis.
Radial plots were introduced by Rex Galbraith (1988a, 1988b, 1994).
Galbraith plot
grouped bar chart is a kind of bar chart which juxtaposes the discrete values for each of the possible value of a given categorical variable, thus providing within group comparison. Grouped bar charts are good for comparing between each element in the categories, and comparing elements across categories. However, the grouping can make it harder to tell the difference between the total of each group.

Pearson's correlation coefficient
negative binomial probability distribution is a discrete probability distribution of the number of successes in a sequence of Bernoulli trials before a specified (non-random) number of failures (denoted r) occur. The negative binomial distribution, also known as the Pascal distribution or Pólya distribution, gives the probability of r-1 successes and x failures in x+r-1 trials, and success on the (x+r)th trial.
negative binomial distribution
a one-tailed test is a statistical test which, assuming an unskewed probability distribution, allocates all of the significance level to evaluate only one hypothesis to explain a difference.
The one-tailed test provides more power to detect an effect in one direction by not testing the effect in the other direction.
one-tailed test should be preceded by two-tailed test in order to avoid missing out on detecting alternate effect explaining an observed difference.
one tailed test
a two tailed test is a statistical test which assess the null hypothesis of absence of difference assuming a symmetric (not skewed) underlying probability distribution by allocating half of the significance level selected to each of the direction of change which could explain a difference (for example, a difference can be an excess or a loss).

A lining of mostly endodermal origin, covered in epithelium, which is involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs. It is at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The sticky, thick fluid secreted by the mucous membranes and gland is termed mucus. The term mucous membrane refers to where they are found in the body and not every mucous membrane secretes mucus[WP].

Class has undergone final review, is ready for use, and will be included in the next release.

Those classes deemed "ready_for_release" will also derived from a chain of ancestor classes that are also "ready_for_release."

universal
Hard to give a definition for. Intuitively a "natural kind" rather than a collection of any old things, which a class is able to be, formally. At the meta level, universals are defined as positives, are disjoint with their siblings, have single asserted parents.

universal
defined class
A defined class is a class that is defined by a set of logically necessary and sufficient conditions but is not a universal
"definitions", in some readings, always are given by necessary and sufficient conditions. So one must be careful (and this is difficult sometimes) to distinguish between defined classes and universal.

named class expression
A named class expression is a logical expression that is given a name. The name can be used in place of the expression.
named class expressions are used in order to have more concise logical definition but their extensions may not be interesting classes on their own. In languages such as OWL, with no provisions for macros, these show up as actuall classes. Tools may with to not show them as such, and to replace uses of the macros with their expansions

The term was added to the ontology on the assumption it was in scope, but it turned out later that it was not.
This obsolesence reason should be used conservatively. Typical valid examples are: un-necessary grouping classes in disease ontologies, a phenotype term added on the assumption it was a disease.

out of scope
The term was added to the ontology on the assumption it was a valid domain entity, but it turns out the entity does not exist in reality.
This obsolesence reason should be used conservatively. For example: Obsoleting class that describes a breed of cow based on a record in an existing database, that was later retracted as faulty (breed does not exist). Do not use this term to obsolete a historic concept (that was once valid, but not anymore).
