regulations of use of social networks, as one of the key components in these networks, serve an important role in controlling the flow of traffic. the study of the harmonization of these terms and regulations can be a significant step to avoid congestion and (users’) rejection in the network. harmonization of traffic control regulations (tcr) among social networks is one of the best solutions...

diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. therefore, this research study was conducted to evaluate time-dependent changes in passive avoidance and y-maze performance in male diabetic rats. for this purpose, male wistar rats were randomly divided into control and diabetic groups. for induction of di...

Synchronization between independently clocked regions in a high performance system is often subject to latencies of more than one clock cycle. We show how the latency can be reduced significantly, typically to half the number of clock cycles required for high reliability, by speculating that a long synchronization time is not required. The small number of synchronization metastability times lon...

We studied the effects of chronic intoxication with the heavy metals lead (Pb2+) and zinc (Zn2+) on memory formation in mice. Animals were intoxicated through drinking water during the pre- and postnatal periods and then tested in the step-through inhibitory avoidance memory task. Chronic postnatal intoxication with Pb2+ did not change the step-through latency values recorded during the 4 weeks...

Increasing latency on paths through the Internet has a negative impact on latency-sensitive applications such as audio and video conferencing, as well as on the perception of responsiveness of many other applications. Measurement is key to addressing this issue, in two ways. First, the symptoms of excessive latency can be hard to isolate, and the causes obscure: the deployment of passive and ac...

diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the humans and experimental animals. due to the anti-diabetic and antioxidant activity of pelargonidin (pg), this research study was conducted to evaluate the efficacy of chronic oral pg on alleviating learning and memory disturbance in streptozotocin-diabetic rats. male wistar rats were divided into...

materials and methods in this experimental study, nmri male mice were placed in groups receiving atropine (0.1 and 1 mg/kg), recipient of mgo-n (1, 2.5, and 5 mg/kg) and groups receiving atropine in effective dose and different doses of mgo-n were used. saline was used as a vehicle for drugs in the control groups. memory was evaluated with a step-down apparatus to determine the coming down late...

A transcription factor, Ndt80p, has been identified that has a critical role in the pathway that controls meiosis--sporulation--in budding yeast. Ndt80p coordinately controls genes that mediate spore formation and progression through the two meiotic divisions; it may also be a target of a checkpoint control.

This paper presents a connection between two real-time models: a deadline-based model and a latency-based model. The importance of the latency-based model is proved through a result showing that two deadlines, instead of a latency constraint, over-constrain the realtime applications. Moreover, we give a deadline-marking algorithm based on the relation between deadlines and latency constraints. ...
