Nowadays, we are experiencing a rapid development in mobile computing because of the sinking prices of the mobile devices and the availability of wireless networks that can connect them. The ability of many of these devices to set up ad-hoc networks by proximity allows face-to-face interaction combined with mobility. However, mobile devices are much weaker in computing power compared with deskt...

BACKGROUND Empiric therapy for healthcare-associated infections remains challenging, especially with the continued development of Gram-negative organisms producing extended-spectrum β-lactamases (ESBLs) and the threat of multi-drug-resistant organisms. Current treatment options for resistant Gram-negative infections include carbapenems, tigecycline, piperacillin-tazobactam, cefepime, ceftazidim...

Six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. In five patients there was unilateral and in one patient bilateral renal artery involvement. The diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. All had atrial fibrillation, proteinuria and elevated ...

that run on one leg. The generalization uf these one-leg algorithms for control of machines with several legs is explored. The generalization is quite simple when multilegged systems run with gaits that use the support legs one at a time. For these gaits the ~ n e-l e g algorithms can be used b o control multilegged running. The cortcept of a virtual leg is introduced to further extend the appr...

Since the times of the old Arab grammarians, the syllable has played a major role in the phonology of classical as well as colloquial Arabic. In the 1970s, phonologists investigated Cairene Arabic (CA) syllable structure and found it to be the domain of some phonological processes, such as emphatic spread, CVC syllables light word final but heavy word internally, limitations on consonant cluste...

SIRT6 is a member of the sirtuin family of class III histone deacetylases. It plays important roles in regulating genomic stability, metabolism, stress response and aging. Our previous study has revealed that SIRT6 attenuates myocardial hypertrophy by inhibiting NF-κB activation, but the related molecular mechanisms remain to be clarified. In the present study, we showed that the p300 acetylase...

This paper proposes an Interactive Chinese Character Learning System (ICCLS) based on pictorial evolution as an edutainment concept in computer-based learning of language. The advantage of the language origination itself is taken as a learning platform due to the complexity in Chinese language as compared to other types of languages. Users especially children enjoy more by utilize this learning...

objective(s): appendicitis remains the most common condition in the pediatric population requiring emergency abdominal operation. management of acute simple appendicitis is well described but controversy remains as to the optimal treatment of complicated appendicitis. common complications of acute appendicitis include: localized peritonitis and abscess formation, flegmon and general peritonitis...
