Experiences with the parallelization of the Phase Space Evolution (PSE) model for electron beam dose calculation are discussed. It is shown that the communication cost in a parallel implementation of the PSE model can be kept small. However, because of the dynamical behaviour of the work load during a PSE simulation special measures must be taken to obtain a good load balance among the processo...

The class A PSE-4 beta-lactamase was used for studying the importance of amino acids in the omega (Omega) loop and its interactions for hydrolysis of beta-lactam antibiotics. By cassette mutagenesis, we replaced the amino acids 163-179 Omega loop in PSE-4 with TEM-1, SHV-1 and Streptomyces albus G beta-lactamase Omega loops. Phenotypic analysis of Escherichia coli recombinants expressing the Om...

designed to support the development and execution of scalable parallel applications on clusters (farms) of distributedand shared-memory Alpha processors running the Digital UNIX operating system. PSE version 1.0 supports the High Performance Fortran (HPF) language; it also supplies generic facilities required by other parallel languages and systems. PSE provides tools to define a cluster of pro...

BACKGROUND The evidence strongly links parental self-efficacy (PSE) to parenting behaviors and child health outcomes. PURPOSE The purpose of this article is to apply the social ecological model to the exploration of contextual factors that influence PSE for parents recovering from substance use disorders (SUDs). METHODS An integrative review of the literature was conducted on PSE, parenting...

The development of pale, soft, and exudative (PSE) breast fillet meat has become an economic burden for the poultry industry worldwide. PSE meat results in 1.0-1.5% loss in moisture and carcass weight, and a 2010 estimate of the Brazilian annual production put the economic loss due to PSE at over US$30 million. In the USA, PSE has caused an annual loss of up to US$200 million to the poultry ind...

This review examines the potential roles of parental self-efficacy (PSE) in parent and child adjustment and the role of parental cognitions in understanding behaviors and emotions within families. The areas in this review include parental competence and psychological functioning, as well as child behaviors, socio-emotional adjustment, school achievement, and maltreatment. There is strong eviden...

A problem-solving environment (PSE) for a distributed high-performance computing (HPC) is proposed to help users to work on distributed computer environment. When users access and use distributed computers for scientific computations, the PSE tells users which computers are available and appropriate for their specific application software by using hardware and software informations specified. T...

Resveratrol (RV, 3,4',5-trihydroxystilbene) is naturally produced by a wide variety of plants including grapes and peanuts (Arachis hypogaea). However, the yield of RV from peanut stem and its potential radiosensitizing effects in prostate cancer (PCa) have not been well investigated. In this study, we characterized RV in peanut stem extract (PSE) for the first time and showed that both RV and ...

The dietary supplementation of Saccharomyces cerevisiae var. boulardii was evaluated in broilers challenged or not challenged with Salmonella Enteritidis (SE) using a 2 × 2 factorial arrangement. Depending on yeast inclusion at 0 (C) or 1 × 10⁹ cfu/kg diet (Y) and SE challenge (0 or log 6.3 cfu/bird) on d 15, the experiment had four treatments C, Y, C-SE, and Y-SE, respectively. Each treatment ...

Within the last several years, the poultry industry has seen a dramatic increase in the occurrence of pale, soft, and exudative (PSE) meat. This problem is known to be associated with a rapid decline in postmortem (PM) muscle pH, which results in inferior protein functionality similar to that found in PSE pork. Many factors such as seasonal changes have been known to influence the occurrence of...
