The POEMS project is creating an environment for end-to-end performance modeling of complex parallel and distributed systems, spanning the domains of application software, runtime and operating system software, and hardware architecture. To enable end-to-end modeling of large-scale applications and systems, the POEMS framework is designed to compose models(More)
In a separator electrode assembly microbial fuel cell, oxygen crossover from the cathode inhibits current generation by exoelectrogenic bacteria, resulting in poor reactor startup and performance. To determine the best approach for improving startup performance, the effect of acclimation to a low set potential (-0.2V, versus standard hydrogen electrode) was(More)
In computer vision, image datasets used for classification are naturally associated with multiple labels and comprised of multiple views, because each image may contain several objects (e.g., pedestrian, bicycle, and tree) and is properly characterized by multiple visual features (e.g., color, texture, and shape). Currently, available tools ignore either(More)
We prove several basic properties for difference ascending chains including a necessary and sufficient condition for an ascending chain to be the characteristic set of its saturation ideal and a necessary and sufficient condition for an ascending chain to be the characteristic set of a reflexive prime ideal. Based on these properties, we propose an(More)
The present study was undertaken to investigate the protective effects of icariin on the learning and memory abilities in Alzheimer's disease model rats and explore its protection mechanisms. Beta-amyloid peptide (Abeta) is a key etiology in Alzheimer's disease and targeting on Abeta production and assembly is a new therapeutic strategy. Six-month (400-600(More)
Recently, advanced microprocessors have incorporated hardware performance counters in their design allowing for new types of analysis via empirical methods. The goal of this analysis continues to be the discovery of analytical/empirical methods to evaluate performance of scaling codes on today's advanced CPU's and to predict effects of architectural(More)
Images are usually associated with multiple labels and comprised of multiple views, due to each image containing several objects (e.g. a pedestrian, bicycle and tree) and multiple visual features (e.g. color, texture and shape). Currently available tools tend to use either labels or features for classification, but both are necessary to describe the image(More)
1. The present study examined the protective effects of icariin against the learning and memory deficits in aluminium-treated rats and its potential mechanisms of action. 2. Qualified rats were treated with 1600 p.p.m. AlCl(3) in drinking water for 8 months and the ability of spatial learning and memory was tested by the Morris water maze. In the place(More)
