In many scenarios, low latency wireless communication assumes two-way connection, such that the node that receives information can swiftly send acknowledgment or other response. In this paper, we address the problem of low latency two-way communication and address it through proposal of a base station (BS) cooperation scheme. The scheme is based on downlink (DL) and uplink (UL) decoupled access...

To study the roles of viral genes in the establishment and maintenance of herpes simplex virus (HSV) latency, we have developed a polymerase chain reaction assay that is both quantitative and sensitive. Using this assay, we analyzed the levels of viral DNA in trigeminal ganglia of mice inoculated corneally with HSV mutants that are defective for virus replication at one or more sites in mice an...

Writing data to a page not present in the file-system page cache causes the operating system to synchronously fetch the page into memory first. Synchronous page fetch defines both policy (when) and mechanism (how), and always blocks the writing process. Non-blocking writes eliminate such blocking by buffering the written data elsewhere in memory and unblocking the writing process immediately. S...

This paper describes a performance examination of the DDR2 DRAM architecture and the proposed cache-enhanced variants. These preliminary studies are based upon ongoing collaboration between the authors and the Joint Electronic Device Engineering Council (JEDEC) Low Latency DRAM Working Group, a working group within the JEDEC 42.3 Future DRAM Task Group. This Task Group is responsible for develo...

OBJECTIVE Establishing reference values for neuroconduction studies regarding the peroneal, tibial and sural nerves in a group of young adults. MATERIALS AND METHODS Neuroconduction was tested (also known as nerve conduction velocity (NCV) tests) on 155 asymptomatic subjects' tibial, peroneal and sural nerves using current conventional techniques, after informed written consent had been obtai...

PURPOSE To determine the effect of optic disc drusen on the latency of the pattern-reversal checkerboard visual evoked potentials (VEPs) and multifocal (mf)VEPs and to better understand the pathophysiology of the condition. METHODS Eighteen eyes with optic disc drusen (10 patients) and 38 control eyes (19 subjects) underwent VEP, mfVEP, and visual field testing. Only one eye of each individua...

The Internet has witnessed a steady rise in malicious traffic including DDoS and worm attacks. In this paper, we study the effect of malicious traffic on the background traffic by analyzing recent traces from two different locations. We show that malicious traffic causes an increase in the average DNS latency by 230% and an increase in the average web latency by 30% even on highly over-provisio...

ZooKeeper [1] is a commonly used service for coordinating distributed applications. ZooKeeper uses leader-based atomic broadcast for writes, so that all state modifications are globally totally ordered, but it allows stale reads from any server for high read availability. This design trades high read throughput for potentially high write latency. Unfortunately, the extent of this tradeoff and t...

Content Delivery Networks (CDNs) are a major enabler of large-scale content distribution for Internetapplications. Many of these applications require high bandwidth and low latency for a satisfactory user experience,e.g, cloud gaming, augmented reality, tactile Internet and vehicular communications [1]. Replication is one of themost prominent solutions to meet the requirements o...

Because the spatial locality of numerical codes is sig-niicant, the potential for performance improvements is important. However, large cache lines cannot be used in current on-chip caches because of the important pollution they breed. In this paper, we propose a hardware design, called the Virtual Line Scheme, that allows the utilization of large virtual cache lines on when fetching data from ...
