Empirical studies suggest that changes in the density of top predators, such as carnivorous fish, freshwater food webs, strongly affect not only fish communities but also various primary and secondary consumers. Based on these findings, we explored how differences utilization (i.e., Northern Snakehead, Channa argus) by humans affected cladoceran community structure well settlement exotic specie...

BACKGROUND Retinitis Pigmentosa (RP) is a hereditary genetic disease causing bilateral retinal degeneration. RP is a leading cause of blindness resulting in incurable visual impairment and drastic reduction in the Quality of life of the patients. Second Sight Medical Products Inc. developed Argus II, a retinal prosthesis system for treating RP. Argus II is the world's first ever-commercial impl...

In this paper, we present an evolving system for the analysis and visualization of parallel application performance on shared memory multiprocessors. Our system couples SimOS, a complete machine simulator, with Rivet, a powerful visualization environment. This system demonstrates how visualization is necessary to realize the full power of simulation for performance analysis. We identify several...

Most studies of lobster chemoreception have focused on the model systems of Panulirus argus (Palinuridae) and Homarus americanus (Nephropidae). We compare antennule morphology across lobsters and conduct the first kinematic study of antennule flicking in a palinurid species other than P. argus. High-speed video analysis shows that Palinurus elephas flicks at a rate more than an order of magnitu...

We have developed Argus-G, a low-cost error detection mechanism for the SIMT cores found in GPGPUs. As GPUs make the transition into general purpose computing, detecting errors and dealing with them will become a more pressing issue. General purpose graphics processing units are increasingly used for scientific computing, where errors, if not detected, can significantly distort the results of t...

PURPOSE Magnetic resonance imaging (MRI) can measure the effects of vision loss and recovery on brain function and structure. In this case study, we sought to determine the feasibility of acquiring anatomical and functional MRI data in recipients of the Argus II epiretinal prosthesis system. METHODS Following successful implantation with the Argus II device, two retinitis pigmentosa (RP) pati...
