This study is intended to clarify the functional role of different ERP components as indicators of the processing of emotions. The effect of emotional connotation of words on hemispheric lateralization is also explored. Visual ERPs were recorded to unilaterally presented positive, negative, and neutral words that should be categorized according to their emotional connotation. The P2 amplitude w...

OBJECTIVES Previously described methicillin-resistant Staphylococcus aureus (MRSA) ST398 strains revealed a high frequency of phenotypic resistance to spectinomycin. However, only a few were found to carry the spc resistance determinant. The aim of this study was to identify the genetic mechanism of spectinomycin resistance among spc-negative MRSA ST398 strains. METHODS Nine spectinomycin-res...

We study combinatorial prediction markets where agents bet on the sum of values at any tree node in a hierarchy of events, for example the sum of page views among all the children within a web subdomain. We propose three expressive betting languages that seem natural, and analyze the complexity of pricing using Hanson’s logarithmic market scoring rule (LMSR) market maker. Sum of arbitrary subse...

The aims of this study were to determine the effects of duodenal and jejunoileal nutrient infusions on small intestinal motor patterns and intestinal contractions in neurally intact and neurally isolated small bowel. Fifteen dogs were prepared with duodenal and jejunal infusion and manometry catheters and a diverting jejunal cannula. Ten of the dogs underwent in situ neural isolation of the jej...

It has been reported that bond strength of resin to tooth structure can be reduced when the bonding procedure is carried out immediately after the bleaching treatment. This study evaluated the effect of bleaching of non-vital teeth bleaching on the shear bond strength (SBS) of composite resin/bovine dentin interface and the influence of delaying the bonding procedures for different time interva...

در صنعت پالایشگاه و پتروشیمی‌ها به دلیل وجود تجهیزات تمام فلزی محیط اسیدی خوردگیتنشی زیاد است با توجه افزایش کاربرد فولادهای زنگ نزن این صنایع پژوهش بررسی اثر ضربات امواج اولتراسونیک بر رفتار خوردگی فولاد 316 (S.S 316) می‌پردازیم. هدف از تأثیر روش تنش‌زدایی برافزایش مقاومت قطعات محیط‌های خورنده است. لازم ذکر که، تنش پسمان نمونه‌ها جوش‌کاری ایجادشده ابتدا نمونه مدنظر استفاده ارتعاش تحت فرکانس 20...

The traditional upscaling approach to greenhouse gas (GHG) emission estimates of inland waters is imprecise, but more precise methods based on environmental drivers are a longstanding challenge. Mexico lacks GHG for its waters, and only sparse scientifically validated information available. This study provides the first from Mexican using 4275 flux measurements 26 distinctive waterbodies one lo...

There has been a proliferation of block-diagram environments for specifying and prototyping DSP systems. These include tools from academia like Ptolemy [6], and commercial tools like SPW from Cadence Design Systems, and Cossap from Synopsys. The block diagram languages used in these environments are usually based on dataflow semantics because various subsets of dataflow have proven to be good m...

For a GaAs filled metallic hole array on a pre-epi GaAs substrate, the free carriers, generated by three-photon absorption (3PA) assisted by strongly enhanced local fields, reduce the refractive index of GaAs in ~200-nm thick active area through band filling and free carrier absorption. Therefore, the surface plasma wave (SPW) resonance, and the related second harmonic (SH) spectrum blue shifts...
