according to iran’s folk medicine, camphor, a crystalline ketone obtained from essential oils of cinnamomum camphora, has both sexual behavior attenuating and enhancing properties. this study examined the effects of camphor on sexual behavior in male rats. twenty four sexually mature male sprague-dawley rats were randomly divided into 4 groups receiving daily i.p. injections of olive oil as veh...

The dramatic increase in the processor-memory gap in recent years has led to the development of techniques like data prefetching that hide the latency of cache misses. Two such hardware techniques are the stream buuer and the stride predictor. They have dissimilar architectures, are eeective for diierent kinds of memory access patterns and require diierent amounts of extra memory bandwidth. We ...

This research explores any potential for an on-chip cache compression which can reduce not only cache miss ratio but also miss penalty, if main memory is also managed in compressed form. However, decompression time causes a critical effect on the memory access time and variable-sized compressed blocks tend to increase the design complexity of the compressed cache architecture. This paper sugges...

This paper presents techniques to integrate the use of variable-latency units in a high-level synthesis (HLS) design methodology. Components used as building blocks (e.g., functional units) in conventional HLS techniques are assumed to have fixed latency values. Variable-latency units exhibit the property that the number of cycles taken to compute their outputs varies depending on the input val...

Chip-multiprocessors (CMPs) must often execute workload mixes with different performance requirements. On one hand, user-facing, latency-critical applications (e.g., web search) need low tail (i.e., worst-case) latencies, often in the millisecond range, and have inherently low utilization. On the other hand, compute-intensive batch applications (e.g., MapReduce) only need high long-term average...

The criterion that existing prefetch schemes apply in prefetching documents from the origin servers into a proxy Web server is usually the probability of each document being accessed in the near future or the popularity of the document. This criterion is not optimum in minimizing the average access latency or maximizing the average hit probability because the factors that affect on the latency ...

background : despite the high incidence and prevalence of cts, there is no exclusive data about normal values increment of motor and sensory distal latencies of median nerve at wrist according to age. this research was done in electrodiagnosis lab of physical medicine & rehabilitation ward in nemazi hospital in shiraz between 1374-1379. material and methods : this study was performed on 1200 ca...

We study the problem of minimizing the maximum latency of flows in networks with congestion. We show that this problem is NP-hard, even when all arc latency functions are linear and there is a single source and sink. Still, an optimal flow and an equilibrium flow share a desirable property in this situation: All flow-carrying paths have the same length, i.e., these solutions are “fair,” which i...
