We compare the X-ray spectra and luminosities, in the 2-8 keV band, of known and suspected cataclysmic variables (CVs) in different environments, assessing the nature of these source populations. These objects include nearby CVs observed with ASCA; the Galactic Center X-ray source population identified by Muno et al.; and likely CVs identified in globular clusters. Both of the latter have been ...

BACKGROUND Cyclic vomiting syndrome (CVS), a chronic disorder characterized by recurrent episodes of vomiting, is frequently unrecognized and is associated with high utilization of emergency department (ED) services. METHODS A web-based survey was posted on the Cyclic Vomiting Syndrome Association (CVSA) website to assess utilization of ED services in patients with CVS. RESULTS Of 251 respo...

Today, many general-purpose register-file (GPRF) architectures implement instructionlevel-parallelism (ILP) techniques to improve performance. Less has been done in this area for the so-called ‘stack architecture’. Nonetheless, stack architectures have many advantages over GPRF architectures. Applying ILP techniques in the stack processor domain might ultimately achieve similar, or better, perf...

Abu-Hijleh, Marwan F., Salah Kassab, Qasim Al-Shboul, and Pallab K. Ganguly. Evaluation of the teaching strategy of cardiovascular system in a problem-based curriculum: student perception. Adv Physiol Educ 28: 59–63, 2004; 10.1152/advan.00010.2003.—It is generally acknowledged that an integrated approach to teaching cardiovascular system (CVS) is clinically relevant. However, very little attent...

W3C’s Semantic Web provides a common framework that allows data to be shared and reused across application and enterprise. As the Semantic Web shapes the future of the Web, it becomes more and more important in software engineering and enterprise application development. While existing ontology engineering tools provide a stack of ontology management support and are used successfully in certain...

Rabies remains a major public health concern in many developing countries. The precise neuropathogenesis of rabies is unknown, though it is hypothesized to be due to neuronal death or dysfunction. Mice that received intranasal inoculation of an attenuated rabies virus (RABV) strain HEP-Flury exhibited subtle clinical signs, and eventually recovered, which is different from the fatal encephaliti...

To determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. In experiments 1 and 2, the effects of salinity on growth indices were studid. Experiments were donein the form of split plot based on RCBD. In each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (ECiws). In experiment 1, ...

The heart rate (HR) and vascular tone (VT) baroreflexes are control systems with negative feedback. As closed-loop control systems with delays, they possess resonance features at approximately 0.1 Hz and 0.03 Hz, which correspond to a ~5-s delay in the blood pressure (BP) response to HR changes and a ~15-s delay in VT response to BP changes, respectively. Unlike a single impact on the cardiovas...

This paper presents a systematic approach to design a Lyapunov based super twisting differentiator. The differentiator will be shown convergent in a finite time whilst the relevant time is accurately estimated.  This differentiator is the main part to establish the sliding surface in higher order sliding mode. The differentiator  is used in the prescribed control structure  to regulate pressure...
