Traditional reliable link layer protocols set their fixed retransmission timers under the assumption that they operate in isolation over the link. Emerging wireless networks however allow multiple link layer sessions to dynamically share the link. To assess the impact of this development, we examine the performance of Web Browsing over a Selective Repeat protocol with fixed retransmission timer...

Cellular 'timers' provide an important function in living cells. Timers help cells defer their responses to stimuli, often for time intervals extending over multiple cell cycles (Figure 1A, left). For example, mammalian oligodendrocyte precursors typically proliferate for ∼ 7 divisions before differentiating during neural development. The bacterium Bacillus subtilis can respond to sudden nutrie...

Introduction Stilbenoid compounds have been described to anti-inflammatory properties in animal models vivo , and shown inhibit Ca2+-influx through the transient receptor potential ankyrin 1 (TrpA1). Methods To study how stilbenoid affect inflammatory signaling we utilized fruit fly, Drosophila melanogaster as a model system. induce intestinal inflammation fed flies with irritant dextran sodium...

This research is a continuation to our work which was published in [1]. Eight different timing VIs are designed and tested. These include ON-Delay, OFF-Delay, Single Shot, Retriggerable Monostable, and Accumulative software-based timers. Using hardware programmable counter/timer chip (DAQ-STC-24bit) and PCI MIO-16E-1 DAQ board, another two precise timers are designed. At the end of the paper, f...

Document History This is the version of a gas burner that contains explicit timer events. In document OLD MS 7/1 a similar gasburner speciication without timers can be found. Document Purpose To show the Oldenburg part of a complete development (gas burner with timers)

Studies on signalling dynamics in living embryos have been limited by a scarcity of in vivo reporters. Tandem fluorescent protein timers provide a generic method for detecting changes in protein population age and thus provide readouts for signalling events that lead to changes in protein stability or location. When imaged with quantitative dual-colour fluorescence microscopy, tandem timers off...

SRM is a generic framework for reliable multicast data delivery. The retransmission requests and replies used in SRM error recovery are multicast to the entire group. SRM uses random timers to avoid the message implosion problem, and the eeectiveness of SRM's duplicate suppression depends critically on the design of these random timers. In order to achieve good performance in a dynamic network ...
