Twitter as a new form of social media can potentially contain much useful information, but content analysis on Twitter has not been well studied. In particular, it is not clear whether as an information source Twitter can be simply regarded as a faster news feed that covers mostly the same information as traditional news media. In This paper we empirically(More)
Virtual machine (VM) systems have traditionally used virtual disks for file storage. Recently, there has been interest in using distributed file systems as a way to provide data storage to guest virtual machines, with the file server running on the same physical machine. Potential advantages include fine-grained data sharing, data protection, versioning,(More)
Endogenously-encoded microRNAs (miRNAs) are a class of small regulatory RNAs that modulate gene expression at the post-transcriptional level. In plants, miRNAs have increasingly been identified by experiments based on next-generation sequencing (NGS). However, promoter organization is currently unknown for most plant miRNAs, which are transcribed by RNA(More)
The Grid2003 Project has deployed a multi-virtual organization, application-driven grid laboratory (" Grid3 ") that has sustained for several months the production-level services required by physics experiments of the Large Hadron Collider at CERN (ATLAS and CMS), the Sloan Digital Sky Survey project, the gravitational wave search experiment LIGO, the BTeV(More)
Several recent works have demonstrated the benefits of through-silicon-via (TSV) based 3D integration [1-4], but none of them involves a fully functioning multicore processor and memory stacking. 3D-MAPS (3D Massively Parallel Processor with Stacked Memory) is a two-tier 3D IC, where the logic die consists of 64 general-purpose processor cores running at(More)
Curcumin, a phenolic compound present in Curcuma longa, has been reported to exert antinociceptive effects in some animal models, but the mechanisms remain to be elucidated. This work aimed to investigate the antinociceptive action of curcumin on neuropathic pain and the underlying mechanism(s). Chronic constriction injury (CCI), a canonical animal model of(More)
BACKGROUND AND PURPOSE The benefit of intravenous thrombolytic therapy in acute brain ischemia is strongly time dependent. METHODS The Get With the Guidelines-Stroke database was analyzed to characterize ischemic stroke patients arriving at hospital Emergency Departments within 60 minutes of the last known well time from April 1, 2003, to December 30,(More)
The growth and morphological differentiation of dendrites are critical events in the establishment of proper neuronal connectivity and neural function. One extrinsic factor, BMP7, has been shown to specifically affect dendritic morphogenesis; however, the underlying mechanism by which this occurs is unknown. Here we show that LIM kinase 1 (LIMK1), a key(More)
The neuroprotective effect of docosahexaenoic acid (DHA) on the glutamate-induced cytotoxicity in rat hippocampal cultures was investigated in the present study. DHA at 5-50 microg/ml successfully protected neurons against the cytotoxicity, markedly increased the cell viability, inhibited both nitric oxide (NO) production and calcium influx, and increased(More)
Prophet is a run-time scheduling system designed to support the efficient execution of parallel applications written in the Mentat programming language [7]. Prior results demonstrated that SPMD applications could be scheduled automatically in a ethernet-based local-area workstation network with good performance [14][16]. This paper describes our recent(More)
