The line spectral frequency (LSF) representation has been proposed by Itakura [l] as an alternative linear prediction (LP) parametric representation. In the context of speech coding, it has been shown [2-61 that this representation has better quantization properties than the other LP parametric representations (such as log area ratios and reflection coefficients). The LSF representation is capa...
STUDY DESIGN A cost-effectiveness analysis conducted alongside a randomized clinical trial. OBJECTIVE To assess the cost-effectiveness of a preoperative cognitive-behavioral therapy (CBT) intervention compared to usual care for patients undergoing lumbar spinal fusion surgery (LSF). SUMMARY OF BACKGROUND DATA The clinical effectiveness of a preoperative CBT intervention for patients undergo...
Angiotensin-converting enzyme 2 (ACE2) is a newly identified regulator of the renin-angiotensin system. This type I membrane-anchored protein has a catalytically active ectodomain that undergoes shedding. Tumor necrosis factor alpha-converting enzyme (TACE) has been shown to be involved in ACE2 shedding. Although pathophysiological significance of ACE2 shedding has been suggested, regulation of...
Reconfigurable hardware resources are very expensive, and yet can be underutilized. This paper describes a middleware capable of discovering underutilized computing nodes with FPGA-based accelerator boards in a networked environment. Using an extended Job management system (JMS), this middleware permits sharing reconfigurable resources at least among the members of the same organization. Tradit...
The LSF/Grainyhead transcription factor family is involved in many important biological processes, including cell cycle, cell growth and development. In order to investigate the evolutionary conservation of these biological roles, we have characterized two new family members in Caenorhabditis elegans and Xenopus laevis. The C.elegans member, Ce-GRH-1, groups with the Grainyhead subfamily, while...
Visual object processing may follow a coarse-to-fine sequence imposed by fast processing of low spatial frequencies (LSF) and slow processing of high spatial frequencies (HSF). Objects can be categorized at varying levels of specificity: the superordinate (e.g. animal), the basic (e.g. dog), or the subordinate (e.g. Border Collie). We tested whether superordinate and more specific categorizatio...
Interleukin-1 (IL-1) is increased in lung lavages from patients with the acute respiratory distress syndrome, and administering IL-1 intratracheally causes neutrophil accumulation and a neutrophil-dependent oxidative leak in lungs of rats. In the present study, we found that rats pretreated intraperitoneally with lisofylline [(R)-1-(5-hydroxyhexyl)-3, 7-dimethylxanthine (LSF)], an inhibitor of ...
استفاده از سازههای سبک فولادی سرد نورد شده (LSF) به عنوان اعضای باربر اصلی سازهای در سالهای اخیر با استقبال خوبی روبرو شده است. دلیل اصلیاین استقبال را میتوان در محاسناین نوع سازهها از جمله سبک وزن بودن، راحتی و سرعت نصب بالای آنها جستجو کرد. یکی دیگر از موارد کاربرد آنها، استفاده به منظورافزایش تعداد طبقات جدید بر روی ساختمانهای موجود میباشد. اما تا زمانی که رفتار سازه ترکیب شده مش...
