| binomial | <mathematics> An expression consisting of two terms connected by the sign plus (+) or minus; as, a+b, or 7-3. Origin: L. Bis twice + nomen name: cf. F. Binome, LL. Binomius (or fr. Bi- + Gr. Distribution ?). Cf. Monomial. 1. Consisting of two terms; pertaining to binomials; as, a binomial root. 2. Having two names; used of the system by which every animal and plant receives two names, the one indicating the genus, the other the species, to which it belongs. <mathematics> Binomial theorem, the theorem which expresses the law of formation of any power of a binomial.

| binomial distribution | The probability distribution associated with two mutually exclusive outcomes; used to model cumulative incidence rates and prevalence rates. The bernoulli distribution is a special case of binomial distribution. (12 Dec 1998) |
| binomial nomenclature | <biology, ecology> The system of having two names (genus and specific epithet, also called Latin binomial) for each organism. (09 Oct 1997) |
| negative binomial distribution | <epidemiology> A distribution which is parameterised by a mean m and an aggregation parameter k which is large when aggregation is small; in fact as k becomes large, the negative binomial distribution approximates the Poisson distribution. (05 Dec 1998) |
| absorption coefficient | <physics> Measures the degree of wave absorption defined as the fraction of wave energy lost as the wave travels a unit distance. See: absorption. (15 Jan 1998) |
| activity coefficient | <chemistry> The factor by which the value of a concentration of a solute must be multiplied to determine its true thermodynamic activity. (06 May 1997) |
| attenuation coefficient | 1. <radiobiology> Compton: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing as a result of Compton effect interactions. 2. Linear: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing due to all absorption and scattering processes. 3. Pair Production: That fractional decrease in the intensity of a beam of ionising radiation due to pair production in a medium through which it passes. 4. Photoelectric Effect: That fractional decrease in the intensity of a beam of ionising radiation due to photoelectric effect in a medium through which it passes. (16 Dec 1997) |
| biological coefficient | Rarely used term denoting the energy expended by the body at rest. (05 Mar 2000) |
| Bunsen's solubility coefficient | The milliliters of gas STPD dissolved per milliliter of liquid and per atmosphere (760 mm Hg) partial pressure of the gas at any given temperature. (05 Mar 2000) |
| velocity coefficient | The rate of transformation of a unit mass of substance in a chemical reaction. (05 Mar 2000) |
| recombination coefficient | <radiobiology> The rate of recombination of positive ions with electrons (or negative ions) in a gas, per unit volume, divided by the product of the particle densities of the two species (positive ions and electrons/negative ions) involved. (09 Oct 1997) |
| mass attenuation coefficient | <physics> The mass attenuation coefficient, u/p, of a material for uncharged ionising particles is the quotient of DN/N by pdl, where DN/N is the fraction of particles that experience interactions in traversing a distance dl in a material of density p. (16 Dec 1997) |
| mass energy absorption coefficient | <physics> The mass energy absorption coefficient, uen/p of a material for uncharged ionising particles is the product of the mass energy transfer coefficient, utr/p and (1 - g) where g is the fraction of the energy of secondary charged particles that is lost to bremsstrahlung in the material. (16 Dec 1997) |
| reflection coefficient | A measure of the relative permeability of a particular membrane to a particular solute; calculated as the ratio of observed osmotic pressure to that calculated from van't Hoff's law; also equal to 1 minus the ratio of the effective pore areas available to solute and to solvent. (05 Mar 2000) |
| partition coefficient | <chemistry> Equilibrium constant for the partitioning of a molecule between hydrophobic (oil) and hydrophilic (water) phases. A measure of the affinity of the molecule for hydrophobic environments and thus, for example: a rough guide to the ease with which a molecule will cross the plasma membrane. (18 Nov 1997) |
| binomial coefficient |
The quantity (x + y) is binomial. If we multiply out the binomial expansion (x + y)?we get x?+ 2xy + y? The coefficients or numerical multipliers of successive terms in this result are 1, 2, 1. See the Additional Note To Additional Note to the previous entry, and the entries Combinations and Pascal Triangle.
