Scalable architectures with non-uniform memory access time (NUMAs) have gained increased popularity in recent years. The increased scalability have increased the demand for scalable lock implementations, such as the queue-based locks of Mellor-Crummey and Scott (MCS lock), and of Craig, Landin and Hagersten (CLH lock). This paper demonstrates that the first-come first-served nature of queue-bas...

Although the above-cited measurements were done in vitro, the results are applicable in vivo because the processes are based on simple laws of physics. They are also corroborated by clinical observations. Increased aPTT has been reported when samples were taken shortly after locking [6–8] . The low gentamicin concentration measured by Zhang et al. prior to the next treatment does not reflect th...

The transition to multicore processors has brought synchronization, a fundamental challenge in computer science, into focus. In looking for solutions to the problem, interest has developed in the lock-free approach, which has been proven to achieve several advantages over the traditional mutual exclusion approach. This thesis studies challenges in interprocess synchronization in shared memory m...

A lock placement describes, for each heap location, which lock guards the location, and under what circumstances. We formalize methods for reasoning about lock placements, making precise the interactions between the program, the heap structure, and the lock placement.

Abstract Background and Aims Introduction: Catheter related blood stream infection (CRBSI) is a dreaded complication in patients with tunneled dialysis catheter often results loss. Antibiotic lock, preventive strategy, not followed for fear of emergence resistant strains. We have reported usefulness 70% alcohol lock cases established CRBSI. The present study was aimed to find CRBSI prophylaxis....

There is growing concern about the development of antibacterial resistance with the use of antibiotics in catheter lock solutions. The use of an antibiotic that is not usually used to treat other serious infections may be an alternative that may reduce the clinical impact should resistance develop. We conducted a randomized controlled trial to compare a solution of minocycline and EDTA with the...

abstract background: despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. one of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. therefore...

BACKGROUND Despite the several strategies available for the management of biofilm-associated ventilator-associated pneumonia, data regarding the efficacy of applying antibiotics to the subglottic space (SS) are scarce. We created an in vitro model to assess the efficacy of antibiotic lock therapy (ALT) applied in the SS for eradication of Pseudomonas aeruginosa biofilm in endotracheal tubes (ET...
