We study the stability of the giant gravitons in the string theory background with NSNS B field. We consider the perturbation of giant gravitons formed by a probe D(8− p) brane in the background generated by D(p− 2)D(p) branes for 2 ≤ p ≤ 5. We use the quadratic approximation to the brane action to find the equations of motion. The vibration modes for ρ , φ and r are coupled, while those of xk’...

In this paper we characterize the latency of the BSD 4.4 alpha implementation of TCP on an ATM network. Latency reduction is a difficult task, and careful analysis is the first step towards reduction. We investigate the impact of both the network controller and the protocol implementation on latency. We find that a low latency network controller has a significant impact on the overall latency o...

The aim of the present study was to evaluate the effect of regular exercise at 2, 4, 6 weeks intervals on spatial learning and memory in Morris water maze and in passive avoidance test in male diabetic rats. For this purpose, male Wistar rats were divided into four groups, two groups of control rats, one sedentary control and one swimming exercise-trained control and two groups of diabetic rats...

Paying off the mortgage, once a widespread rite of passage for homeowners approaching retirement, has become less common in recent years. Concerns are mounting that the increased prevalence of housing debt among older homeowners could compromise financial security in retirement by expanding housing affordability problems, crimping essential nonhousing spending, increasing vulnerability to home ...

This paper addresses the problem of measuring frame latency in ATM switches. The frames consisting of several ATM cells may arrive with numerous gaps between cells. It is important that the gaps present in the input stream be not counted towards the switch's contribution to the frame delay. The proposed solution called "MIMO" (Message-In Message-Out) latency improves upon FILO (First-In Last-Ou...

temporal lobe epilepsy (tle) is a disorder of the central nervous system in which hippocampus is mostly involved and causes memory impairment. kindling is a model of inducing epilepsy which is created through pentylenetetrazol (ptz) administration. this study examines the role of the aqueous extract of boswellia on the learning and development of brain (formation of dendritic branches and axons...

A novel two-step paradigm was used to investigate the parallel programming of consecutive, stimulus-elicited ('reflexive') and endogenous ('voluntary') saccades. The mean latency of voluntary saccades, made following the first reflexive saccades in two-step conditions, was significantly reduced compared to that of voluntary saccades made in the single-step control trials. The latency of the fir...
