Parameter, distinguished

Note that the quantity (1- Q D)) can be thought of as a disorder parameter distinguishing the different regimes of behavior. Numerical measurements of this disorder parameter around the transition point at. which the zigzag pattern collapses spontaneously (i.e. around etc 3.92) suggest a critical-like behavior [kaneko89a] ... [Pg.395]

The inhibitory effect of zinc on soluble and cell wall-bound acid phosphatases in vitro was studied in an attempt to find parameters distinguishing between tolerant and non-tolerant ecotypes of grasses (Wainwright and Woolhouse, 1978 Cox and Thurman, 1978). [Pg.154]

Considerable work has been focused on determining the asymptotic null distribution of -2 log-likelihood -ILL) when the alternative hypothesis is the presence of two subpopulations. In the case of two univariate densities mixed in an unknown proportion, the distribution of -ILL has been shown to be the same as the distribution of [max(0, Y)f, where Y is a standard normal random variable (28). Work with stochastic simulations resulted in the proposal that -2LL-c is distributed with d degrees of freedom, where d is equal to two times the difference in the number of parameters between the nonmixture and mixture model (not including parameters used for the probability models) and c=(n-l-p- gl2)ln (31). In the expression for c, n is the number of observations, p is the dimensionality of the observation, and g is the number of subpopulations. So for the case of univariate observations (p = 1), two subpopulations (g = 2), and one parameter distinguishing the mixture submodels (not including the mixing parameter), -2LL-(n - 3)/n with two... [Pg.734]

Both parameters distinguish the degree of helicity of the incident radiation. For instance, rj assumes the value of unity for plane polarized light and zero for circularly polarized light, and may therefore be regarded as a direct measure of the degree of ellipticity of the laser beam. However, only (, which is zero for plane polarized light, differentiates the sense of handedness in circular or elliptical polarizations, and for the circularly polarized cases we have... [Pg.78]

Substitution on boron prior to (or in the absence of) addition that leads to salt formation only arises (1) provided the boron is not sterically or electronically shielded by its substituents, and (2) when good leaving groups are initially bonded to the metalloid. This latter parameter distinguishes reactions of alkoxyboranes from similar ones involving R3B species in which only addition takes place. ... [Pg.336]

To try to answer such a question, it is worth considering what parameters distinguish the various receptor subtypes. The receptor families differ in their effector systems While the 5-HTg receptors are ion channels, the 5-HTi receptors inhibit adenylylcyclase, the S-HT, 5-HTg and 5-HT, receptors stimulate adenylylcyclase, the S-HTj receptors stimulate phospholipase C and the 5-HTj receptors are probably coupled to a different effector system. Why then are there so many 5-HT, receptors (S-HTj, 5-HT,p, 5-HT,j, , 5-HT,e and 5-HT,p) ... [Pg.321]

The parameter distinguishing between these two scenarios is the spreading parameter S, which measures the energy difference between the bare substrate (Tsa) and the substrate covered with a film of liquid (qsL + 7) ... [Pg.7]

Both uniaxial positive (rod-like) and uniax-al negative (disc-like) nematics exist. The nematic order parameter, distinguishes between the two possibilities [15]. If Q p refers to uniaxial positive nematics (rodlike), then, - Q p describes uniaxial negative nematics (disc-like). As a result, the N-1 transition is necessarily first order for geometric reasons [15]. [Pg.414]

Herein, we describe the use of PCA to assess how libraries of compounds produced using these synthetic routes compare to natural products and what structural and physicochemical parameters distinguish them from synthetic drugs and drug-like libraries. The information harnessed from PCA can also direct downstream... [Pg.226]
