One formidable problem in language technology is the word sense disambiguation (WSD) problem: disambiguating the true sense of a word as it occurs in a sentence (e.g., recognizing whether the word "bank" refers to a river bank or to a financial institution). This paper explores a strategy for harnessing the linguistic abilities of human beings to develop(More)
Many data centers extensively use virtual machines (VMs), which provide the flexibility to move workload among physical servers. VMs can be placed to maximize application performance, power efficiency, or even fault tolerance. However, VMs are typically repositioned without considering network topology, congestion, or traffic routes. In this demo, we show(More)
INTRODUCTION The motor symptoms and signs of early-onset idiopathic Parkinson's disease (PD) in Hoehn and Yahr (H&Y) stage-1 are generally unilateral. We hypothesized that there would be detectable differences in the quantitative MRI parameters in these PD patients between the hemispheres contralateral to the clinically symptomatic and non-symptomatic body(More)
Dynamic parallelism allows GPU kernels to launch additional kernels at runtime directly from the GPU. In this paper we show that dynamic parallelism enables relatively simple high-performance graph algorithms for GPUs. We present breadth-first search (BFS) and single-source shortest paths (SSSP) algorithms that use dynamic parallelism to adapt to the(More)
Fc gamma receptor I (FcγRI) contributes to protective immunity against bacterial infections, but exacerbates certain autoimmune diseases. The sole high-affinity IgG receptor, FcγRI plays a significant role in immunotherapy. To elucidate the molecular mechanism of its high-affinity IgG binding, we determined the crystal structure of the extracellular domains(More)
Vertical GaN based Light Emitting Diodes (VLED) on metal alloy base were realized [1] and characterized for solid state lighting application. An operating voltage of less than 2.9 Voltage from a high efficiency and high power blue LED was achieved. And, an efficiency of more than 120 lumens/watt from a white LED was achieved also. The dissipate heat more(More)
