We trace the crafting of expert narratives during the initial months of the COVID‐19 pandemic in Mainland China, Hong Kong, and the United States. By expert narratives, we refer to how experts drew different lessons from past disease experiences to guide policymakers and the public amidst uncertainty. These expert narratives were mobilized in different

面向配电网弹性提升的多端口E-SOP 分布鲁棒优化配置 [PDF]
为提升高比例新能源渗透的配电网在小概率-高损失极端事件下的弹性,提出了一种基于分布鲁棒优化的多端口智能储能软开关(E-SOP)配置模型。首先,构建含多端口E-SOP的配电网运行模型;进而,采用KL散度构建新能源机组出力模糊集,并以投资成本与配电网失负荷成本之和最小为目标,建立E-SOP双层三阶段分布鲁棒规划模型;采用列与约束生成算法实现分布鲁棒模型的拆分求解。最后,在IEEE 33节点算例中对模型和算法进行了验证,结果表明E-SOP可有效提升储能对不同馈线的功率支撑能力,从而增强配电网弹性。

Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
Abstract This revision of the classification of eukaryotes follows that of Adl et al., 2012 [J. Euk. Microbiol. 59(5)] and retains an emphasis on protists. Changes since have improved the resolution of many nodes in phylogenetic analyses. For some clades even families are being clearly resolved.

2021年玛多MW7.4地震强震加载及其对周围地区应力扰动的影响
2021年5月22日在青海玛多发生MW7.4地震,为了探究玛多地震的不同滑动模型对周围地区及断层应力的加卸载作用,本文首先以GNSS数据为约束,结合中国地震局地质研究所公布的玛多地震同震滑动模型(模型A)断层面几何结构反演获得同震滑动模型(模型C),再分别利用模型A、模型B(USGS)、模型C计算玛多地震对周围地区及断层的应力加卸载作用。结果显示:① 模型C矩震级为MW7.46,最大滑动量为3.39 m,主体破裂位于0—10 km深度范围,整体破裂东侧大于西侧,滑动分布相对于模型A也更加均匀平滑 ...

直流断路器是城市轨道牵引供电系统的关键设备。目前轨道直流牵引供电系统配置的断路器以机械式空气断路器为主,其开断过程存在触头和熄弧栅片烧蚀、故障电流开断速度慢等问题,而混合式直流断路器造价过于昂贵。针对以上问题,分析了单/多端口直流断路器的关断原理及其在轨道牵引中的故障隔离性能、具体配置方法以及各自优缺点,通过仿真分析,验证了混合式直流断路器在轨道牵引系统故障中的阻断能力,并着重研究了多端口直流断路器在目前城铁牵引直流系统中应用改造的可行性。

The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.
