Vancomycin has been used as the last resort in the clinical treatment of serious Staphylococcus aureus infections. Vancomycin-intermediate S. aureus (VISA) was discovered almost two decades ago. Aside from the vancomycin-intermediate phenotype, VISA strains from the clinic or laboratory exhibited common characteristics, such as thickened cell walls, reduced autolysis, and attenuated virulence. ...

mount bidkhan stratovolcano is located in the central iranian volcanic belt. it is composed of several types of pyroclastic deposits, lava flows and intrusive bodies. textural and chemical characteristics of plagioclase phenocrysts from the eruptive products volcanic edifice, record complex magma mixing events over the lifetime of the volcano. evidences such as xenocrystic high al+ti clinopyrox...

One challenge of economics is that the systems treated by these sciences have no perfect metronome in time and no perfect spatial architecture—crystalline or otherwise. Nonetheless, as if by magic, out of nothing but randomness one finds remarkably fine-tuned processes in time. We present an overview of recent research joining practitioners of economic theory and statistical physics to try to b...

Extreme events such as natural or technological disasters challenge society’s capabilities for planning and response. While advanced technologies and modeling techniques continue to expand how society can limit and manage extreme events, flexibility and an ability to improvise remain crucial in responding to them. By analyzing a case from the response to the 2001 World Trade Center attack, this...

A methodology is proposed for studying rare events in stochastic partial differential equations in systems that are so large that standard large deviation theory does not apply. The idea is to deduce the behavior of the original model by breaking the system into appropriately scaled subsystems that are sufficiently small for large deviation theory to apply but sufficiently large to be asymptoti...

Who could disagree with the seemingly common-sense reasoning that: “We must learn from the things that go wrong.”? Despite major investments to improve patient safety, relatively few evaluations demonstrate convincing reductions in risk, harm, serious error or death. This disappointing trajectory of improvement from learning from errors or Safety-I as it is sometimes known has led some research...

The influence of the multi-boson effects on pion multiplicities, single-pion spectra and two-pion correlation functions is discussed in terms of an analytically solvable model. It is argued that spectacular multi-boson effects are likely to be observed only in the rare events containing sufficiently high density fluctuations. The possibilities of unlike particle correlations for a study of the ...

background: hadjelia truncata is a nematode that causes lesions in the gizzard lining of pigeons, which may even lead to death. the aim of this study was to introduce alphitobius diaperinus as a new intermediate host for hadjelia truncata . methods: h. truncata infection was identified in a pigeon flock in ahvaz city, khuzestan province, iran by performing fecal examination and autopsy. adult a...

BACKGROUND The relationship of circulating levels of high-sensitivity C-reactive protein (CRP) with cardiovascular disease (CVD) risk, particularly with consideration of effects at intermediate levels of risk, has not been fully assessed. METHODS AND RESULTS Among 3006 offspring participants in the Framingham Heart Study free of CVD (mean age, 46 years at baseline), there were 129 hard corona...
