类泛素蛋白及其中文命名

泛素家族包括泛素及类泛素蛋白,约20种成员蛋白.近年来,泛素家族领域取得了迅猛发展,并已与生物学及医学研究的各个领域相互交叉.泛素家族介导的蛋白质降解和细胞自噬机制的发现分别于2004和2016年获得诺贝尔奖.但是,类泛素蛋白并没有统一规范的中文译名. 2018年4月9日在苏州召开的《泛素家族介导的蛋白质降解和细胞自噬》专著的编委会上,部分作者讨论了类泛素蛋白的中文命名问题,并在随后的\"泛素家族、自噬与疾病\"(Ubiquitinfamily,autophagy anddiseases)苏州会议上提出了类泛素蛋白中文翻译草案,此草案在参加该会议的国内学者及海外华人学者间取得了高度共识.冷泉港亚洲\"泛素家族、自噬与疾病\"苏州会议是由美国冷泉港实验室主办、两年一度、面向全球的英文会议.该会议在海内外华人学者中具有广泛影响,因此,参会华人学者的意见具有一定的代表性.本文介绍了10个类别的类泛素蛋白的中文命名,系统总结了它们的结构特点,并比较了参与各种类泛素化修饰的酶和它们的生物学功能.文章由45名从事该领域研究的专家合作撰写,其中包括中国工程院院士1名,相关学者4名,长江学者3名,国家杰出青年科学基金获得者18名和美国知名高校华人教授4名.他们绝大多数是参加编写即将由科学出版社出版的专著《泛素家族介导的蛋白质降解和细胞自噬》的专家

塔里木盆地西南缘灌区低洼农田水盐运移特征/Soil Water and Salt Migration of Low-lying Parts of Irrigation Area in the Southwestern Tarim Basin[J]

为科学治理塔里木盆地西南缘灌区重度盐渍化,对其一处低洼农田水盐进行监测.结果显示:排除漫灌影响,7月初至11月初,农田地下水埋深呈单峰型,表现为监测前期缓慢上升,8月初达到最大值,后波动性降低;而地下水矿化度一直缓慢降低.0～60 cm土壤总盐量表现为单峰型,监测前期缓慢升高,8月达到最大值,后缓慢降低.相关分析表明,整个监测时期,农田地下水埋深、矿化度、0～60 cm总盐量均表现为正相关,且随着土壤深度的增加,总盐量与地下水埋深、矿化度的相关程度增大

2005～2015年CERN光合有效辐射数据集

光合有效辐射在生态学、农学以及气候学等多个学科中都有重要的应用价值。它是揭示物质与能量交换过程的基本生理变量,是光合潜力、潜在产量的评估研究和作物生长模拟研究、土壤碳的固定模拟研究中不可缺少的关键数据之一。该数据集涵盖了中国8个典型陆地生态类型、中国生态系统研究网络(CERN)下属的40个辐射观测站观测的光合有效辐射日均值,时间跨度为2005～2015年。通过对传感器的集中标定与规范的数据质量控制方案,保障了观测数据的可靠性与可比性。采用光谱仪、辐射标准灯传递辐射基准方案,对光合有效辐射传感器进行集中标定与比对,标定精度小于5%,符合世界气象组织(WMO)标准;采用极值法对观测的光合有效辐射数据进行质量控制

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
