用Noether耦合方法,在求得了超对称Noether流和内对称Noether流后,引入规范场、引力微子场、Yang—Mills场及费米场之间的相互作用,构造了OS_P(N/4)超引力的拉氏量,并证明了其不变性。由于得到超对称Noether拉氏量和内对称Noether拉氏量,使该理论包含有更广泛的各场的自相互作用和它们之间的相互作用,可将四种相互作用包含其中。     

Neural mechanisms of perceptual grouping in human visual cortex

The current work examined neural substrates of perceptual grouping in human visual cortex using event-related potential (ERP) recording. Stimulus arrays consisted of local elements that were either evenly spaced (uniform stimuli) or grouped into columns or rows by proximity or color similarity (grouping stimuli). High-density ERPs were recorded while subjects identified orientations of perceptual groups in stimulus arrays that were presented randomly in one of the four quadrants of the visual field.Both uniform and grouping stimulus arrays elicited an early ERP component (C1), which peaked at about 70ms after stimulus onset and changed its polarity as a function of stimulated elevations. Dipole modeling based on realistichead boundary-element models revealed generators of the C1 component in the calcarine cortex. The C1 was modulated by perceptual grouping of local elements based on proximity, and this grouping effect was stronger in the upper than in the lower visual field. The findings provide ERP evidence for the engagement of human primary visual cortex in the early stage of perceptual grouping.     

A flexible DSP-based network for real-time image-processing

This paper proposed a general purpose real-time image processing system based on a flexible DSP-based Network, which is implemented by a high bandwidth communication channel, links. The links is realized using FPGA and provides a bandwidth of 12.8 Gbit/s. Using the links, The topologic of muhi-DSP system can be changed online to meet the variabilities of the parallel algorithm of image processing.The system can be assembled with utmost tens of boards and maintain the high communication speed. Analysis of the system adaptivity to image processing is testified followed by actual results.     

Genomic segmental polymorphisms in inbred mouse strains

By analyzing genomic copy-number differences using high-resolution mouse whole-genome BAC arrays, we uncover substantial differences in regional DNA content between inbred strains of mice. The identification of these apparently common segmental polymorphisms suggests that these differences can contribute to genetic variability and pathologic susceptibility.
