THE concept of preemptive analgesia to reduce the magnitude and duration of postoperative pain was paved in 1983 by Woolf, who showed evidence for a central component of postinjury pain hypersensitivity in experimental studies. Subsequently, an overwhelming amount of experimental data demonstrated that various antinociceptive techniques applied before injury were more effective in reducing the ...

Guaranteeing quality for differentiated services while ensuring resource efficiency is an important and yet challenging problem in large computing clusters. Priority scheduling is commonly adopted in production systems to minimize the response time of high-priority workload by means of preempting the execution of low-priority workload when faced with limited resources. As a result, the system p...

OBJECTIVES Cytomegalovirus (CMV) infections in liver transplant recipients are common and result in significant morbidity and mortality. Intravenous ganciclovir or oral valganciclovir are the standard treatment for CMV infection. The present study investigates the efficacy of oral valganciclovir in CMV infection as a preemptive treatment after liver transplantation. METHODS Between 2012 and 2...

Sustainable vascular or peritoneal access for dialysis is very important patients undergoing therapy, and trouble occasionally involved with unexpected occurrence of complications. Once occurs, therapy might be discontinued followed by a life-threatening state end-stage kidney disease. Bacterial infection, massive bleeding, thrombosis in hemodialysis acute infectious peritonitis chronic encapsu...

Modern GPUs are broadly adopted in many multitasking environments, including data centers and smartphones. However, the current support for the scheduling of multiple GPU kernels (from different applications) is limited, forming a major barrier for GPU to meet many practical needs. This work for the first time demonstrates that on existing GPUs, efficient preemptive scheduling of GPU kernels is...

This report deals with the analysis of the performance of different versions of the wide spread Transport Control Protocol (TCP) over 3G UMTS networks. This analysis is done through simulations executed on the Network Simulator version 2 (NS2) and its Enhanced UMTS Radio Access Network Extension (EURANE). Different tool enhancements were developed in order to make this project possible. This pa...

Pain, which is often inadequately treated, accompanies the more than 23 million surgical procedures performed each year and may persist long after tissue heals. Preemptive analgesia, an evolving clinical concept, involves the introduction of an analgesic regimen before the onset of noxious stimuli, with the goal of preventing sensitization of the nervous system to subsequent stimuli that could ...

In safety-critical applications, the use of advanced real-time scheduling techniques is significantly limited by the difficulty of finding tight estimations of worst-case execution parameters. This problem is further complicated by the use of cache memories, which reduce the predictability of the executing threads due to cache misses. In this paper, we analyze the effects of preemptions on wors...

We consider the scheduling problem of minimizing the average weighted completion time on identical parallel machines when jobs are arriving over time. For both the preemptive and the nonpreemptive setting, we show that straightforward extensions of Smith’s ratio rule yield smaller competitive ratios compared to the previously best-known deterministic on-line algorithms, which are (4+ ε)-competi...
