RankGene is a program for analyzing gene expression data and computing diagnostic genes based on their predictive power in distinguishing between different types of samples. The program integrates into one system a variety of popular ranking criteria, ranging from the traditional t-statistic to one-dimensional support vector machines. This flexibility makes(More)
Research on the political consequences of social movements has recently accelerated. We take stock of this research with a focus on movements in democratic polities and the United States in comparative and historical perspective. Although most studies demonstrate the influence of the largest movements, this research has not addressed how much movements(More)
Multiple system atrophy (MSA) is a progressive neurodegenerative disease characterized by glial cytoplasmic inclusions containing insoluble α-synuclein. Since Ca(2+) plays an important role in cell degeneration, [Ca(2+)]( i ) in α-synuclein-overexpressed human glioma cells was analyzed by Fura-2 fluorometry. Overexpression of α-synuclein increased the basal(More)
—Wireless multi-hop access networks are an increasingly popular option to provide cost-efficient last-mile Internet access. However, despite extensive research, performance of even basic communication services, such as TCP, is still problematic. Measurements collected on a wireless testbed indicate that the poor performance of multi-hop access networks is(More)
Wireless multi-hop networks have been envisioned to have many potential applications, e.g., a small stand-alone network for a group of mobile users (Mobile Ad Hoc Networks), a cost-efficient stub-network to connect to the Internet (Wireless Mesh Networks), or a self-organized community network connecting houses together (Wireless Community Networks).(More)
Accumulated evidence indicates chronic systemic injection of D-galactose mimics aging progress induced by oxidative stress. We addressed whether memory impairment in this model was associated with the cholinergic septohippocampal degeneration. Rats injected with D-galactose for 6 weeks showed impairment of spatial learning and memory as measured by the(More)
