Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

The Study of “Barefoot Doctors” Narrative in the Culture Revolution Literature [PDF]
赤脚医生制度是文化大革命(1966-1976)期间,乡村地区所特有的医疗制度,在这个制度的背景下,出现了一个特殊的医生群体——赤脚医生,由此产生了一系列的描写赤脚医生故事的文学文本,即“赤脚医生叙事”。这种叙事形态,与中国现当代文学中的疾病医疗叙事、日常生活叙事、乡村叙事等脉络都存在复杂的关联性。第一,赤脚医生叙事中的疾病叙事内容,承接了中国现代文学的疾病叙事源流,延续了后者有关“病体”的隐喻性书写,例如有关“病体”和健康身体的对比,具有阶级、政治批判的隐喻。而与后者不同的是 ...

针对雷击输电线路的问题,提出使用集总经验模态分解法(ensemble empirical mode decomposition,EEMD)对输电线路进行监测。ATP仿真雷电通过绕击与反击向高压输电线路注入雷电波的过程,并通过时频分析第一阶IMF分量瞬时频率分别确定了雷电绕击与反击时的频率特征和雷击发生时刻,结果表明:雷电绕击与反击时线路中将激发大量高频成分且最高频率可达100 k Hz;EEMD可以克服模态混叠实现输电线路信号分解;在100 Hz1 k Hz以及>10 k Hz,反击的频率成分更丰富 ...

RETRACTED: The Growing Tide of Antiscience Sentiment: A Global Concern
ABSTRACT The growing tide of antiscience sentiment represents a critical global challenge, with particularly visible manifestations in the United States. This viewpoint examines how the rejection of scientific consensus threatens academic institutions, public health, and technological progress worldwide.

利用ATP-EMTP仿真程序对单回和同塔双回750 kV输电线路典型杆塔的反击耐雷性能及其影响因素进行了仿真计算研究。研究中杆塔采用了多波阻抗模型,考虑了雷电波在杆塔中的传播速度、杆塔呼称高度及杆塔接地电阻等因素的影响,采用统计法确定750 kV超高压线路的反击耐雷性能。研究结果表明:杆塔中的传播速度影响不可忽略;随着杆塔高度的降低,冲击接地电阻的减小,线路反击性能增强;导线排列方式和档距的变化,对线路反击性能影响很小;对于ZB329和ZGU315型杆塔,仅其单回反击跳闸率都会高于预期雷击跳闸率 ...

Jung, Bion and the Crucible of War
Abstract WWI had a transformative effect on the lives and ideas of both Carl Jung and Wilfred Bion. Both suffered intense and life‐changing experiences, which they carried with them for the rest of their lives. For Jung, living in neutral Switzerland, the febrile tension of the war emerged in a stream of archetypal imagery, while his daily life ...

建筑物接地系统雷电冲击特性主要是指雷电流通过接地装置向周围大地散流的特征,通常表现为冲击电流对接地装置作用后局部暂态地电位升高导致地电位反击。利用土壤测试数据及接地系统图模拟实际建筑物接地模型下雷击冲击试验反击地电位特性,通过搭建CDEGS地电位仿真模型实现地电位分布计算并验证了反击试验结果的可靠性,得出地电位分布与注入点位置、接地系统支路分布之间影响关系,对雷击分流接地系统预防地电位反击提出了合理优化措施。

Policy instruments attitudes and support for government responses against Covid‐19
Abstract An individual's political attitudes have been documented as the most important predictor of acceptance of government measures against the COVID‐19 pandemic. Their effect, however, is somewhat unclear and cannot be reduced to one dimension. In this article, we test whether general attitudes toward policy instruments might, together with left ...
