In this paper, we describe a RAT (radio access technology) agnostic approach referred to as OMMA (Opportunistic Multi-MAC Aggregation) that can aggregate multiple RATs operating over independent spectral bands. Aggregation and/or traffic shaping is performed above the air interface protocol stacks but below the IP layer. We investigate the problem of minimizing the average packet latency (the s...

background:  optical coherence tomography (oct) is a non-invasive instrument, which can be used to estimate the thickness of the retinal nerve fibre layer (rnfl) and provides an indirect measurement of axonal destruction in multiple sclerosis (ms). the main aim of this study was to find out any correlations between p100 latency in visual evoked potential (vep) and rnfl thickness. methods: the p...

STUDY OBJECTIVE To assess usual nightly sleep duration of patients referred for a Multiple Sleep Latency Test (MSLT). DESIGN Retrospective chart review. SETTING Military, hospital-based, sleep center. PATIENTS Fifty-four patients with excessive daytime sleepiness referred for an MSLT. INTERVENTIONS None. MEASUREMENTS AND RESULTS Self-reported average nightly sleep duration (6.13 +/- 1...

Checkpointing and rollback is a technique for minimizing loss of computation in presence of failures. Two metrics can be used to characterize a checkpoint-ing scheme: (i) checkpoint overhead (increase in the execution time of the application because of a checkpoint), and (ii) checkpoint latency (duration of time required to save the checkpoint). For many checkpoint-ing methods, checkpoint laten...

For millimeter-wave (mm-wave) buffer-aided tandem networks consisting of relay nodes and multiple channels per hop, we consider two traffic allocation schemes, namely local allocation and global allocation, and investigate the end-to-end latency of a file transfer. We formulate the problem for generic multi-hop queuing systems and subsequently derive closed-form expressions of the end-to-end la...

The phase of the complex output of a narrow band Gaussian filter is taken to define the latency of the auditory evoked response M100 recorded by magnetoencephalography. It is demonstrated that this definition is consistent with the conventional peak latency. Moreover, it provides a tool for reducing the number of averages needed for a reliable estimation of the latency. Single-event latencies o...

Multifarious psychological constructs are indexed by the mean latency difference (MLD), the within-subject difference between mean response latency on two tasks. Two associations consistently emerge in mean latency data. Firstly, across subjects, mean latencies on distinct tasks are positively correlated. This correlation arises from individual differences in general rates of information proces...

INTRODUCTION  The effects of lead on children's health have been widely studied. AIM  To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. METHODS  This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluation...

In this letter we propose a new analytical iterative method for calculating the throughput and average cell latency of the crosspoint queued switch with random scheduling algorithm under the bursty traffic model. This method is verified by comparing it with simulation results, which shows a very good match. To the authors’ knowledge, this is the first analytical method for performance analysis ...
