Many concurrent data-structure implementations – both blocking and non-blocking – use the well-known compare-and-swap (CAS) operation, supported in hardware by most modern multiprocessor architectures, for inter-thread synchronization. A key weakness of the CAS operation is its performance in the presence of memory contention. When multiple threads concurrently attempt to apply CAS operations t...

Cas is a multidomain signaling protein that resides in focal adhesions. Cas possesses a large central substrate domain containing 15 repeats of the sequence YXXP, which are phosphorylated by Src. The phosphorylation sites are essential for the roles of Cas in cell migration and in regulation of the actin cytoskeleton. We showed previously that Src catalyzes the multisite phosphorylation of Cas ...

This paper describes a theory of constant foundation for evolving C2 activities through time and space. The theory is conducive to C2 domain analysis and engineering implementation. Based on an established scientific problem-solving paradigm in complex space, the Common Agility Space (CAS) representation, to enable the description, measurement, and analysis of C2 activities. CAS codifies two C2...

A credit card authorization system (CAS) is a large information system performing diverse activities such as purchase authentication, balance transfer, cash advances, etc. One characteristic of CAS is its frequent update to satisfy the needs of customers and newly enforced governmental laws. Thus, CAS should be designed to minimize the effects of updates, for which high reusability of the CAS c...

A facile spectrophotometric method is proposed for determination of Colchicoside (COLSID) in bulk and in dosage forms using ceric ammonium sulphate (CAS). Method involves addition of a known excess of CAS to COLSID and determination of residual CAS with a fixed amount of either Azure B (AB), measuring absorbance at 633nm or Safranin O (SO), measuring absorbance at 519 nm. Calibration graphs are...

Le délai pour la levée d'un garrot sur un membre est limité, tout retard, surtout après la 3ème heure expose à un risque d'amputation de celui-ci. Notre objectif a été de rapporter trois cas de gangrène ischémique de membre par oubli d'un garrot après un prélèvement sanguin, afin d'interpeler le personnel soignant sur ses dangers. Il s'est agi de trois nourrissons dont deux de 3 mois et un de 5...

Since the introduction of carotid stenting (CAS), a combined treatment for bilateral lesions using carotid endarterectomy (CEA) and CAS has been developed. However, there has been only 1 report about CEA then CAS. Herein we describe 2 patients with bilateral severe carotid stenosis who were treated by CEA for the symptomatic side and CAS for the contralateral asymptomatic side. A 71-year-old ma...

Childhood apraxia of speech (CAS) is a paediatric speech sound disorder in which precision and consistency of speech movements are impaired. Most children with idiopathic CAS have normal structural brain MRI. We hypothesize that children with CAS have altered structural connectivity in speech/language networks compared to controls and that these altered connections are related to functional spe...

Introduction: The benefits of statin treatment in patients undergoing carotid angioplasty with stenting (CAS) have not been well established. This study aimed to determine the short-term effect of statins on periprocedural cerebrovascular complications and on the restenosis rate following CAS. Methods: The medical records of 59 consecutive patients who underwent CAS from December 2010 to Decemb...

BACKGROUND The objective of this study was to review the recent literature regarding the neurocognitive consequences of carotid endarterectomy (CEA) and carotid stenting (CAS). METHODS AND RESULTS A PubMed and Web of Science search was conducted using the key words 'carotid' in combination with 'cognitive', 'cognition', 'neurocognition', 'neurocognitive', 'neuropsychology', and 'neuropsycholo...
