强非局域非线性介质中的库墨-高斯孤子簇

利用自相似技术求解一个在强非局域非线性条件下的（2＋1）维非线性薛定鄂方程,我们得到一个精确的库墨高斯（Kummer-Gass）解析解,结果表明,这种库墨高斯孤子可以形成一族空间孤子簇。数值模拟体现了空间孤子传输稳定性的特征。

Advances in the study of helminth mitochondrial genomes and their associated applications

Helminths, including flatworms and roundworms, are abundant organisms that have a variety of life histories. Of these, the genera Schistosoma, Echinococcus, Trichinella are notable parasites of veterinary and medical importance, and cause substantial socio- economic losses throughout China and the rest of the world. Genetic markers in the mitochondrial (mt) genome have proven use- ful for systematic, ecological, evolutionary and population studies, and the growth of mt genomic research has increased in the last two decades. Technological improvements, such as the long-polymerase chain reaction method and high-throughput se- quencing have allowed minute amounts of DNA from single worms, biopsy samples or microscopic organisms to be used for whole mt genome characterization. To facilitate the retrieval, annotation and analyses of mitochondrial features, multiple data- bases and specific software have also been designed and established. This review focuses on current progress, applications and perspectives regarding helminth mt genomics. To date, the complete mt genomes for 93 species of helminths have been sequenced and analyzed. Analyses of the mt genes, including gene content, arrangement, composition and variation have revealed unique features among the helminths when compared with other metazoans. This provides important data concerning their functional and comparative mitochondrial genomics, molecular taxonomy and characterization, population genetics and systematics, and evolu- tionary history. Moreover, mt genome data for parasitic helminths are important for diagnosis, epidemiology and ecology of in- fections. Mitochondrial genome data offer a rich source of markers for the systematics and population genetics of socioeconomi- cally important parasitic helminths of humans and other animals.     

桑蚕蛹甲壳素及壳聚糖的提取与制备工艺研究
