A broad class of parallel server systems is considered, for which we prove the steady-state asymptotic independence workloads, as number servers goes to infinity, while system load remains sub-critical. Arriving jobs consist multiple components. There are job classes, and each may be one two types, determines rule according components add workloads servers. The model enough include special case...

Motivated by forthcoming data from the Sloan Digital Sky Survey, we present a theoretical framework that can be used to interpret Principal Component Analysis (PCA) of disk galaxy properties. We use the formalism introduced by Mo, Mao, & White to compute the observable properties of galaxies in a number of model populations, varying assumptions about which physical parameters determine structur...

BACKGROUND Although black cardiac patients receive fewer revascularization procedures than whites, it is unclear whether this has a detrimental impact on outcomes. The objective of our study was to compare 6-month functional status and angina outcomes among blacks and whites with documented coronary disease and to assess whether differential use of revascularization procedures affects these out...

Background: Physicians’ and nurses’ experience of the COVID-19 pandemic and its physical and psychological consequences can be associated with changes in biological and hormonal levels, experienced as fatigue, restlessness, disruptions in one's mood, and sleep quality. This study examined the role of depression and death anxiety in contracting COVID-19 among healthcare staff. Methods: The stat...

Background and aims: The aim of this study was the modeling of the incidence rates of Colorectal, breast and prostate cancers using a shared component model in order to explore the spatial pattern of their shared risk factors (i.e., obesity and low physical activity) affecting on cancer incidence, and also to estimate the relative weight of these shared components. Methods: In this study,...

today, self-objectification is define by evaluating the others based on physical appearance, beauty and sexual attractiveness, it’s a major source of women suffering especially female students and reduce resilience and self-compassion and mental health of them is endangered. the aim of this study is investigating the relationship between self-objectification with resilience and self-compassion ...
