BACKGROUND Cell-free protein expression (CFPE) comprised of in vitro transcription and translation is currently manipulated in relatively dilute solutions, in which the macromolecular crowding effects present in living cells are largely ignored. This may not only affect the efficiency of protein synthesis in vitro, but also limit our understanding of the functions and interactions of biomolecul...

OBJECTIVE This administrative data-linkage cohort study examines the association between prison crowding and the rate of post-release parole violations in a random sample of prisoners released with parole conditions in California, for an observation period of two years (January 2003 through December 2004). BACKGROUND Crowding overextends prison resources needed to adequately protect inmates a...

In crowding, the perception of an object deteriorates in the presence of nearby elements. Obviously, crowding is a ubiquitous phenomenon, as elements are rarely seen in isolation. One of the main characteristics of crowding is that the elements themselves are not rendered invisible, but their features are averaged[1] or substituted[2] with those of neighboring elements. Recently, Harrison and B...

INTRODUCTION The state of emergency department (ED) crowding in Pennsylvania has not previously been reported. METHODS We assessed perceptions of ED crowding by surveying medical directors/chairs from Pennsylvania EDs in the spring of 2008. RESULTS A total of 106 completed the questionnaire (68% response rate). A total of 83% (86/104) agreed that ED crowding was a problem; 26% (27/105) repo...

Despite growing research for residential crowding effects on housing market and public health perspectives, relatively little attention has been paid to explore and model spatial patterns of residential crowding over space. This paper focuses upon analyzing the spatial relationships between residential crowding and socio-demographic variables in Alexandria neighborhoods, Egypt. Global and local...

The purpose of this study was to assess the prevalence of permanent incisor crowding in the maxillary and mandibular arches among Saudi schoolchildren. Three hundred and fifty four dental casts of Saudi schoolchildren attending pediatric dentistry and orthodontic clinics in College of Dentistry at King Saud University in Riyadh, Saudi Arabia were studied by one examiner. The children’s age rang...

In this paper, an efficient multi-objective artificial bee colony optimization algorithm based on Pareto dominance called PC_MOABC is proposed to tackle the QoS based route optimization problem. The concepts of Pareto strength and crowding distance are introduced into this algorithm, and are combined together effectively to improve the algorithm’s efficiency and generate a set of evenly distrib...

introduction: creating a calm and stress-free environment affects education significantly. the effects of the emergency department overcrowding (edo) on the training of emergency medicine residents (emr) is a highly debated subject. therefore, this study aimed to evaluate the effect of edo on efficiency of emr’s education. methods: in this cross-sectional study, the effects of overcrowding on e...
