Crosstalk noise is a crucial factor affecting chip performance in deep submicron technologies. Among all possible crosstalk noise sources, clock is the most common aggressor as well as victim..Crosstalk on clock nets can increase clock jitter, which may degrade significantly the system performance. It is therefore imperative to design clock buffers to reduce the coupling effects. In this paper,...

VC merging allows many routes to be mapped to the same VC label, thereby providing a scalable mapping method that can support thousands of edge routers. VC merging requires reassembly buffers so that cells belonging to different packets intended for the same destination do not interleave with each other. This document investigates the impact of VC merging on the additional buffer required for t...

Mounting evidence of wildlife population gains from targeted conservation practices has prompted the need to develop and evaluate practices that are integrated into production agriculture systems and targeted toward specific habitat objectives. However, effectiveness of targeted conservation actions across broader landscapes is poorly understood. We evaluated multiregion, multispecies avian den...

Riparian forest buffers can improve stream water quality, provided they intercept and remove contaminants from surface runoff and/or shallow groundwater. Soils, topography, hydrology, and surficial geology detemine the capability of forest buffers to intercept and treat these flows. This paper describes landscape analysis techniques for identifying and mapping locations where forest buffers can...

Sindbis vectors have shown remarkable antitumor efficacy and tumor-targeting capacity in animal models and hold promise for cancer therapy. Different packaging systems are used to produce propagation-incompetent Sindbis vectors. However, the vectors produced using either DH-BB single helper RNA or split helper RNA can spread in permissive cell cultures. We investigated the mechanisms of vector ...

Data prefetching via helper threading has been extensively investigated on Simultaneous MultiThreading (SMT) or Virtual Multi-Threading (VMT) architectures. Although reportedly large cache latency can be hidden by helper threads at runtime, most techniques rely on hardware support to reduce context switch overhead between the main thread and helper thread as well as rely on static profile feedb...

We analyze a model of heavily utilized bottleneck buffer in this paper. We show that the nature of traffic leaving the buffer is determined by the buffer length/number of TCPs ratio. If this ratio is above a critical value, TCP can stay in the congestion avoidance phase and it can generate periodic traffic after a transient period. If the ratio is below a critical value then the congestion wind...

The sorting buffers problem is motivated by many applications in manufacturing processes and computer science, among them car-painting and file servers architecture. The input is a sequence of items of various types. All the items must be processed, one by one, by a service station. We are given a random-access sorting buffer with a limited capacity. Whenever a new item arrives it may be moved ...
