Cell end-localized Dma1 is involved in polar growth by regulating the ubiquitination of Tip1/CLIP-170 in fission yeast

细胞极性是大多数细胞的一个基本特征，细胞极性的建立是细胞周期中的重要事件。裂殖酵母S.pombe中的CLIP170家族蛋白Tip1能够监督微管使其沿着细胞的纵轴生长，并参与运输极性因子到达细胞端部的过程。人类肿瘤抑制因子Chfr同源蛋白Dma1是纺锤体检验点蛋白和胞质分裂的抑制因子。已有的研究发现它会泛素化修饰SIN(septationinitiationnetwork)通路中的Sid4，导致Plo1激酶不能定位到SPB(spindlepolebody)，从而抑制SIN信号通路和阻止胞质分裂。 我们实验室的前期结果显示Dma1除定位在胞质、SPB和中隔外，也定位在细胞生长端，并在细胞端部与T...Cell polarization is a major event of the cell cycle and underlies the function of most cells. In the fission yeast Schizosaccharomyces pombe, the microtubule plus end-tracking protein Tip1, a CLIP170 protein family member, is required to guide fission yeast cytoplasmic microtubules to their target zone located at the cell ends and involved in delivering cell polarity factors to cell tips.

Transmission shielding technology for bistatic sonar

基线附近区域为双基地声呐的探测盲区,当目标位于基线区域时,目标回波与强直达波干扰同时同向到达,基于空域滤波等的传统直达波抑制方法失效。为实现双基地声呐对盲区内目标的探测,提出了一种适用于多发射阵元系统的发射声屏蔽技术。发射声屏蔽技术利用目标回波与直达波相异的多途信道结构特性,自动屏蔽在接收站位置处的直达波而不影响目标回波,且不需接收站进行任何后续处理。在已知回波信道信息时,发射声屏蔽技术可进一步实现对回波信号的聚焦,提高信干比。仿真结果表明,在不同信道条件下发射声屏蔽均能有效抑制直达波干扰。利用发射声屏蔽技术,双基地声呐能够实现对基线区内目标的检测。The area near the baseline is a dead zone for bistatic sonar.The echo and the strong direct wave will arrive in the same place simultaneously when the target is in the baseline area and the direct wave suppression method based on a spatial filter will fail.To detect targets in the dead zone,a transmission shielding method for a multi-element transmit system is proposed.The transmission shielding automatically suppresses the direct wave at the receiving station utilizing structural differences in multiple channels between the echo and the direct wave.The transmission shielding further focuses on the echo,so as to improve the Signal-Noise Ratio,using known echo channel information.The simulation results show the transmission shielding method can suppress direct wave interference for different multipath channels.Bistatic sonar can detect targets in the baseline area utilizing the transmission shielding method.国家自然科学基金资助项目(51179034); 海洋工程国家重点实验室(上海交通大学)资助项目(1211

植物模式标本的考证与数字化:以中国国家植物标本馆为例

模式标本是最重要的植物标本,是确定植物学名的依据,是植物分类学家从事植物系统分类研究必不可少的科学材料,也是开展专科专属研究、编写国家或地方植物志、进行植物区系调查研究、开发利用和保护植物资源的重要基本资料。但模式标本的人为和自然毁损难以避免,模式标本及其标签信息的数字化使得模式标本的形态、地理分布、采集等主要信息得到最大限度的永久保存,可以极大地方便模式标本信息的共享,可以为科学研究人员或相关人员提供植物形态、地理分布、历史变迁等多方面的信息。本文以中国科学院植物研究所国家植物标本馆维管束植物模式标本数字化建设为例,详细介绍了规范化整理模式标本的方法、模式标本数字化的操作流程,并通过大量实例介绍了模式标本考订的过程、常见问题的处理方法等,以期为其他单位开展模式标本数字化建设提供经验

Construction of the Traditional Chinese Medicine external nursing treatment outpatient clinic based on the Guo Hailing Traditional Chinese Medicine Nursing Inheritance Studio (基于“郭海玲中医护理传承工作室”中医护理外治门诊的构建)

Traditional Chinese Medicine (TCM) nursing clinic is an advanced nursing practice with Chinese characteristics. It takes the overall view of TCM and the principle, uses the characteristics of TCM nursing technology to meet the diversified health needs of patients, and plays a unique advantage in disease prevention and health care. TCM nursing clinic is able to improve patient satisfaction, broaden the scope of nursing services and enhance the professional level nursing. However, in the process of its development, there are also bottlenecks such as prescription right, inability to follow, and weak discipline development. The construction of Traditional Chinese Medicine Nursing Inheritance Studio is effective to drive the development of disciplines, develop the inheritance of TCM nursing, and realize mutual promotion and mutual development. (中医护理门诊是一种具有中国特色的高级护理实践模式, 其以中医的整体观和辨证施护为原则, 运用中医特色护理技术, 满足患者多元化的健康需求, 在疾病预防保健中发挥着独特优势。中医护理门诊能够提升患者满意度, 拓宽护理工作服务范围, 提升护理专业化水平。但是其发展过程中也有处方权、无法可依、学科发展薄弱等瓶颈, 中医护理传承工作室的建设, 可以有效带动学科发展, 发成中医护理传承, 实现相互促进相互发展。

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
