Understanding divergent domestication traits from the whole-genome sequencing of swamp- and river-buffalo populations

Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.     

Exponential stability of switched genetic regulatory networks with both stable and unstable subsystems

This paper concerns the stability analysis problem for stochastic delayed switched genetic regulatory networks (GRNs) with both stable and unstable subsystems. By employing the piecewise Lyapunov functional method combined with the average dwell time approach, we show that if the average dwell time is chosen sufficiently large and the derivative of the Lyapunov-like function for unstable subsystems is bounded by certain kind of continuous function, then exponential stability criteria of a desired degree are guaranteed. The derived results show that the minimal average dwell time is proportional to the time delays. Finally, an example is given to illustrate the effectiveness of the derived results.     

应用“点线面分析法”提高空间想象能力

组合体的读图与画图在工程制图课程中是重点和难点,正确理解投影面垂直面的“类似形”投影是关键。文中作者提出用“点线面分析法”来求解“类似形”。综合应用“点线面分析法”和“形体分析法”,能够帮助学生识读和绘制组合体,并提升学生的空间想象能力。     

长治地区并减自然村的可行性调查分析报告

并减自然村是合理调整农村结构的重要举措,是自然村现代化改造必须解决的问题.自然村的现代化改造是新农村建设的重要环节,是农村实现跨越式发展的必由之路,是新农村建设中一项具有艰巨性、复杂性与长期性的工程,也是新农村建设中一个新的问题.基于理论联系实际的思路,本文拟以长治地区自然村的分布情况及当前自然村并减工作进展与问题为基础,论证并减自然村的重大意义以及当前深入开展并减自然村的可行性,并在长治地区的自然村调查数据的基础上详尽分析各类自然村并减的切入点,提出若干并减自然村的新思路.     

Gasless laparoscopy for benign gynecological diseases using an abdominal wall-lifting system

Objectives: The use of gasless laparoscopy with an abdominal wall-lifting device for benign gynecological diseases was compared to conventional laparoscopy with CO_2 pneumoperitoneum. Methods: From February 2007 to July 2007, 76 women with uterine and/or adnexal benign diseases and candidates for laparoscopic surgery were recruited in this study. Thirty-two women underwent gasless laparoscopic surgery and 44 women underwent pneumoperitoneum laparoscopic surgery. Results: Diverse pathologies, including adnexal cyst, uterine myoma and ectopic pregnancy, were treated successfully with gasless laparoscopic surgery. Compared with the patients in the pneumoperitoneum group, the similar hospital stay (P=0.353) and in-traoperative blood loss (P=0.157) were observed. However, the mean operative time in the gasless group was significantly longer than that in the pneumoperitoneum group (P=0.003). No severe intraoperative or postoperative complications were found in either group, except for one case of laparotomic conversion in the pneumoperitoneum group due to dense pelvic adhesions. The total hospital charges were significantly less in the gasless group than in the pneumoperitoneum group (P=0.001). In 38 cases of ovarian cyst resection, the mean operative time in the gasless group remained longer than that in the pneumoperitoneum group (P=0.017). The total hospital charges were also significantly less in the gasless group than in the pneumoperitoneum group (P<0.001). Con-clusion: Our preliminary results demonstrated that the laparoscopic procedure using the gasless technique was a safe, effective method to treat benign gynecological diseases. Moreover, it was easy to master. As a minimally invasive treatment, gasless laparoscopic surgery provides a good choice to patients in the undeveloped regions in China without increasing the patients' and the government's burden significantly.     

我国科技人员自引现象分析

0引言 自引现象是科学著文过程中比较普遍的现象,R.Tagliacozzo和A.Dimitroff分别于1977年和1995年研究了自然科学文献和图书情报学文献的自引现象[1,2].Tagliacozzo的研究表明植物生理学论文自引率为16.6%,神经生理学论文的自引率为17.5%,并且发现自引引文"年龄更青".他认为自引现象与合著者多少、著文作者的文献书目内容多少或论文量是无关的.
