Low penalty cascaded operation of a monolithically integrated Quantum Dot 1×8 port optical switch

A novel Quantum Dot monolithically integrated 1×8 switch is shown to provide robust routing of data at 10Gb/s modulation rates. Two cascaded switches providing, 1×64 functionality, operate with a power penalty of only 0.9dB. © VDE VERLAG GMBH.

Results of the Austrian-Ceylonese hydrobiological mission 1970 of the 1st Zoological Institute University of Vienna (Austria) and the Department of Zoology of the Vidyalankara University of Ceylon, Kelaniya. Pt 18. Freshwater musssels bivalvia

Till now there have been only two families of Bivalves with four genera known from freshwater in Ceylon. The material used for this study consists of members of three genera. This study deals with the family Unionidae, the family Corbiculidae is only represented by one specimen.

云南18 个民族Y染色体双等位基因单倍型频率的主成分分析

世居云南的少数民族中,壮、傣、水、布依、布朗、德昂、佤、彝、白、怒、哈尼、傈僳、拉祜、纳西、景颇、阿昌、基 诺和独龙18 个民族是由“羌”、“濮”、“越”3 大部落群体演化而来,是云南的土著居民。利用PCR2RFL P 方法对这18 个土著民族进行Y染色体上13 个双等位基因位点进行基因分型。结果显示,不同历史族源的民族群体在Y染 色体双等位基因单倍型分布上具有一定的差异:在百越后裔民族群体中以单倍型H11 、H12 为主要分布;在氐羌后 裔民族中以单倍型H5 、H6 和H8 为主要分布;在百濮后裔民族群体中主要单倍型分布为H6 、H8 和H11 。进一步 主成分分析表明,百越后裔民族群体和氐羌后裔民族在主成分图上聚为两组,提示父系基因库有不同的来源,与历 史记载相印证。
