Dynamical four-point susceptibilities measure the extent of spatial correlations in the dynamics of glass forming systems. We show how these susceptibilities depend on the lengthscales that necessarily form part of their definition. The behavior of these susceptibilities is estimated by means of an analysis in terms of renewal processes within the context of dynamic facilitation. The analytic r...

One hundred four isolates of Campylobacter jejuni from poultry in Alberta, Canada, collected during 2001 were tested for resistance to 10 antimicrobial agents using agar dilution. This study provides a baseline of resistance profiles and the mechanisms of resistance observed in C. jejuni in poultry from Alberta, Canada.

We present an asymptotically exact solution of a local copper-oxide model abstracted from the multi-band models. The phase diagram is obtained through the renormalization-group analysis of the partition function. In the strong coupling regime, we find an exactly solved line, which crosses the quantum critical point of the mixed valence regime separating two different Fermi-liquid (FL) phases. A...

Expectations about the shape of statistical interactions play a crucial role in the study of differential susceptibility and other types of person-environment interplay. These expectations shape methodological guidelines and inform the interpretation of empirical findings; however, their logic has never been explicitly examined. This study is the first systematic exploration of the evolution of...

This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regressio...

We study the quark mass dependence of various response functions, which contribute to chiral susceptibilities and the specific heat in the staggered fermion formulation of two-flavour QCD. This yields information about the critical exponents α, β and δ. In the case of the chiral susceptibility, obtained as derivative of the chiral order parameter with respect to the quark mass, we calculate all...

In the past four years, there have been several attempts to apply studies of animal behaviour to conservation. Knowledge of individuals' behaviour has the potential to alter understanding of how populations fare in fragmented habitats, the responses of populations to exploitation and disturbance, disease susceptibility, effective population size, captive breeding and reintroduction efforts, and...

We present an analysis of the power fluctuations in the statistical steady state of a passively mode-locked laser. We use statistical light-mode theory to map this problem to that of fluctuations in a reference equilibrium statistical physics problem and, in this way, study the fluctuations nonperturbatively. The power fluctuations, being noncritical, are Gaussian and proportional in amplitude ...

Children are not little adults. They have unique patterns of environmental exposure and developmentally determined susceptibilities that increase their risk of disease following toxic environmental exposure. Evidence is accumulating that children's exposure to toxic chemicals in the environment is contributing to changing patterns of pediatric disease.
