Reproductive biology is a uniquely important topic since it is about germ cells, which are central for transmitting genetic information from generation to generation. In this review, we discuss recent advances in mammalian germ cell development,including preimplantation development, fetal germ cell development and postnatal development of oocytes and sperm. We also discuss the etiologies of female and male infertility and describe the emerging technologies for studying reproductive biology such as gene editing and single-cell technologies.

Source Identification of Network Diffusion Processes with Partial Observations

第37届中国控制会议

作者： chaoyi shi Qi Zhang Tianguang Chu College of Engineering Peking University School of Information Technology & Management University of International Business & Economics

We consider the problem of provenance identification for diffusion processes on social networks based on cascade information observed from a small set of nodes during the observation windows. The diffusion dynamics are described by the susceptible-infected(SI) model and a constrained maximum likelihood(ML) estimator is formulated to maximize the probability of the diffusion provenance. The identification approach consists of two steps: first, a pruning rule is defined to obtain a set of suspected provenance nodes from susceptible node observers;and then a correlation coefficient is maximized to find the provenance node from the candidate ones. Experiments on synthetic networks and real-world networks verify the effectiveness of our approach.

15至20世纪,海河流域南系历史上著名的湖泊——大陆泽和宁晋泊经历了从宽广到干涸的巨大变迁.对于二泊演变的原因,此前学者从未做过专门的分析和研究.本文以明清时期丰富的历史文献为依据,对影响湖泊演变的各大自然和人文因子进行了深入探讨,得出如下基本结论:海河南系水系格局不断变迁导致湖泊水源补给发生迅速改变,是促使湖泊相应发生显著扩张与萎缩,并最终导致湖泊消亡的直接主要动因.此外,来自河流的泥沙淤积,气候的干湿变化,人类拦水筑坝、占垦涸泊等活动加速了湖泊的演变与消涸.

滹沱河是海河子牙河系最主要的支流。明清时期,滹沱河平原段善淤、善决、善徙,被称为“决不可以人力治者”。本文通过对明清相关史料的收集、分析、整理,首次对明以来滹沱河的变迁改道进行了具体详细的恢复,进而发现滹沱河在不同历史时段,其流经方向、河道稳定性、主要河患影响范围和程度都有不同的特点。据此,文章将滹沱河变迁分成四个阶段———①明初(1368年)至明正德十二年(1517年);②明正德十二年(1517年)至清顺治二年(1645年);③清顺治二年(1645年)至清同治七年(1868年);④清同治七年(1868年)至今———并对其分别进行了介绍,最后总结了明清时期滹沱河变迁的特点和规律。
