A short root mutant ksrl with the Kasalath background was isolated from an EMS-mutagenized population in rice. The root length of 6-day-old ksr1 seedlings was only about 20% of the wild type. Genetic analysis indicated that the short root phenotype of ksrl was controlled by a recessive mutation in a single nuclear-encoded gene. To map the ksrl mutation, an F2 population was generated by crossing the ksrl mutant with Nipponbare. The KSR1 locus was linked to the SSR marker RM1223 on rice chromosome 4. Eight new SSR markers and two InDel markers were developed around this marker. KSR1 gene was further mapped to a 155 kb region, flanked by the InDel marker 4-24725K and the SSR marker RM17182.

针对欧氏距离在高维空间中不能忠实反映样本位于非线性流形上的相似关系,提出基于马氏距离的t分布随机邻域嵌入算法(Mt-SNE)。用改进的算法对输入数据进行降维处理,并将输出结果作为支持向量机(SVM)的输入向量进行分类,采用ASHRAE制冷系统故障实验数据进行模型训练与验证。结果表明,该算法比传统的线性降维算法主元分析法(PCA)和非线性降维算法t分布随机邻域嵌入(t-SNE)都有更好的特征提取能力,可以用于冷水机组故障数据的特征提取。

丽金龟亚科Rutelinae隶属于鞘翅目Coleoptera多食亚目Polyphaga金龟总科Scarabaeoidea金龟科Scarabaeidae。世界性分布,全世界已知7族235属4200余种,中国目前记录3族25属(亚属),共526种(亚种)。丽金龟成虫为植食性,可取食植物范围广,幼虫土栖,主要取食植物根部,部分种类是农林业害虫。因此,对其开展分类学研究,对农林业生产具有理论意义。本文通过全面核查文献及统计分析,回顾和总结了丽金龟亚科分类学研究历史,并重点介绍了我国的研究现状。目前已开展的丽金龟亚科研究工作仍以新种发表为主,缺乏高质量的分类修订工作及系统发育研究。另外,丽金龟亚科是鞘翅目中重要的植食性昆虫之一,开展深入的生物多样性研究,对于探讨甲虫的多样性和与植物协同进化关系有重要意义。

AIM:To investigate and evaluate the technical feasibility and clinical effectiveness of fluoroscopically guided peroral uncovered expandable metal stent placement to treat gastric outlet and duodenal obstructions. METHODS:Fifteen consecutive patients underwent peroral placement of Wallstent^(TM)Enteral Endoprosthesis to treat gastric outlet and duodenal obstructions(14 malignant,1 benign).All procedures were completed under fluoroscopic guidance without endoscopic ***-up was completed until the patients died or were lost,and the clinical outcomes were analyzed. RESULTS:The technique success rate was 100%,and the oral intake was maintained in 12 of 14 patients varying from 7 d to 270 *** patients remained unable to resume oral intake,although their stents were proven to be patent with the barium *** patient with acute necrotizing pancreatitis underwent enteral stenting to treat intestinal obstruction,and nausea and vomiting *** patients died during the follow- up period,and their mean oral intake time was 50 d. No procedure-related complications *** migration to the gastric antrum occurred in one patient 1 year after the procedure,a tumor grew at the proximal end of the stent in another patient 38 d post-stent insertion. CONCLUSION:Fluoroscopically guided peroral metal stent implantation is a safe and effective method to treat malignant gastrointestinal obstructions,and complications can be ignored based on our short-term *** for this procedure should be discreetly considered because a few patients may not benefit from gastrointestinal insertion,but some benign gastrointestinal obstructions can be treated using this procedure.
