We cultured and sampled the animals at different developmental stages （eggs and larvae）, and used in-situ hybridization and northern blotting to document the spatial and temporal changes in AmphiCaM expression. The alimentary tract dominates the development from the late neurula stage to the adult stage. AmphiCaM expression increased significantly in the alimentary tract during the late neurula stage and remained elevated in the adults. Our results indicate that AmphiCaM is involved in the differentiation of the alimentary tract in amphioxus; and furthermore, provide an insight into the change in function of CaM genes during evolution.展开更多

It also presents some policy proposals to relieve the contradiction betweencoal and power, including to intensify macroscopic regulation between industries and regions, solve theproblem of power coal transportation and reduction or exemption of tax on coal industry and circulationlinks, through secondary distribution to regulate profit difference among industries.展开更多

The blind MMSE linear detector can be implemented with batch processes or sequential processes. In this paper, according to the different implementations of blind detectors, the authors analyze two schemes of the blind MMSE multiuser receiver for space-time coded CDMA Systems and make a comparison between both schemes by the theoretical analysis and numerical simulations.展开更多
