This paper considers humming-based systems for human verification and identification. Humming of a target person is modeled as a Gaussian mixture model, and the matching score between a target model and humming is computed as the likelihood of humming given a target model. Verification is performed by comparing the matching score to the likelihood given a(More)
Alzheimer's disease (AD) is closely associated with synaptic dysfunction, and thus current treatments often aim to stimulate neurotransmission to improve cognitive impairment. Whereas the formation of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex is essential for synaptic transmission, the correlation between(More)
In neuroexocytosis, SNAREs and Munc18-1 may consist of the minimal membrane fusion machinery. Consistent with this notion, we observed, using single molecule fluorescence assays, that Munc18-1 stimulates SNARE zippering and SNARE-dependent lipid mixing in the absence of a major Ca(2+) sensor synaptotagmin-1 (Syt1), providing the structural basis for the(More)
— A time-based analog-to-digital converter(ADC) employing a multi-phase voltage-controlled oscillator(VCO) is presented. The VCO is based on a ring oscillator which converts analog input voltage to phase information. Digital output is produced by a phase quantizer which consists of a counter for coarse quantization and phase detector for fine quantization.(More)
One of the most critical steps to integrating heterogeneous e-Business applications using different XML schemas is schema mapping, which is known to be costly and error-prone. Past research on schema mapping has not fully utilized semantic information in the XML schemas. In this paper, we propose a semantic similarity analysis approach to facilitate XML(More)
