  • 简介:AbstractThis study aimed to describe a case of a patient with the spontaneous dissolution of zona pellucida (ZP) during cleavage embryo development after intracytoplasmic sperm injection (ICSI). This patient experienced early abortion due to fetal chromosome 8 abnormality and received ICSI at 31 years of age. Time-lapse monitoring of embryo cleavage and blastocyst culture was performed, and we found that the ZP of embryos 1, 2, 4, and 5 dissolved gradually during the cleavage stage of embryo development. Five blastocysts that developed from 2 pronuclear zygotes were analyzed using next-generation sequencing, and one frozen-thawed blastocyst was transferred, resulting in intrauterine pregnancy. The results of amniotic fluid puncture showed normal fetal chromosomes. To our knowledge, this is the first report of ZP dissolution during the cleavage-stage embryo; however, the exact mechanism remains unknown. The morphological changes inferred that the granular matter in the periocular space was related to the dissolution of ZP through time-lapse observation.

  • 简介:基于散布途径的连续顺序,为垂直地不同类的飞机平行媒介的一个完整的向量放射的转移模型(SOSVRT)被开发了。克服集中的计算负担,由截断与一个几何系列散布订单的一种简单近似技术被用来减少计算时间。有三种对称关系和二个相互的反的操作员的阶段矩阵的分析Fourier分解被实现了进一步改进计算效率。改进精确性,一个processing以后过程被实现精确地插入内推在任意的角度的Stokes向量。有为随机面向的过寺院生活的球状体的气氛的基准的比较证明为各个的优秀同意司烧参数(在0.1%以内)。SOSVRT被测试了放射的转移建模因为对RT3的不同大气的状况,它基于双增加的方法,和结果证明SOSVRT在向量精确、更有效,特别为光薄空气,它是在极化的放射的转移模拟的最普通的盒子。SOSVRT在Fortran90被写,代码由联系作者是自由地可存取的。关键词放射的转移-极化-散布的连续顺序-散布

  • 简介:在没有规模的网络上称为随机的散步免疫策略的新奇免疫策略被建议。与另外的已知的免疫策略不同,这策略如下工作:一个节点随机从网络被选择。从这个节点开始,随机去它的邻居节点之一;如果现在的节点没被使免疫,那么使它免疫并且继续随机的散步;否则回到以前的节点并且随机再走。这个过程被重复直到节点的某个部分被使免疫。由理论分析和数字模拟,我们发现这策略与另外的已知的免疫策略比较是很有效的。

  • 简介:target language readers might have different feeling between translation and the original. Those translations which added translator’s own emotion were not according with the standard of translation. Translation should avoid to add personal emotion to the original works. 3.3 Free translation skill needs extensive knowledge and culture of both source language and target language. Free translation gives translators some leeways. Translators should use then correctly. Not only should translators comprehened the meaning of the original message,translaors should use free translation. Free translation is a translation skill which is active. But free translation can not add personal emotion to the original works. Translation must be acceptable which use free translation. And free translation skill needs extensive knowledge and culture of both source language and target language. If a translator wants to use literal translation and free translation proficiently,也会说你的坏话. Free translation does not strachy the form of the original. If translators want to use free translation proficiently. You’d better grasp extensive knowledge and culture of both source language and target language. CONCLUTION
