Positive emotion in posttraumatic stress disorder: A global or context‐specific problem?

Journal of Traumatic Stress, Volume 36, Issue 2, Page 444-456, April 2023., 2023
Abstract Problems with positive emotion are an important component of posttraumatic stress disorder (PTSD), with competing perspectives as to why. The global model suggests that people with PTSD experience a relatively permanent shift in their capacity for positive emotion regardless of context, whereas the context‐specific model posits access to the ...

A landscape‐scale framework to identify refugia from multiple stressors

Conservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract From a conservation perspective, quantifying potential refugial capacity has been predominantly focused on climate refugia, which is critical for maintaining the persistence of species and ecosystems. However, protection from other stressors, such as human‐induced changes in fire and hydrology, that cause habitat loss, degradation, and ...

基于蒙特卡洛算法的1100 kV变压器套管椭圆形双均压环参数优化设计

Dianci bileiqi, 2023
为了降低特高压变压器套管引线端的最大场强，避免局放产生的影响，对1 100 kV变压器套管引线端的双均压环进行优化设计。通过改变表面曲率可以调节均压环上的场强最大值，由此设计参数化椭圆形均压环，应用蒙特卡洛算法分别对椭圆形上、下均压环的参数b、参数c和旋转角度θ进行参数优化分析，得到了椭圆形上下均压环的最佳参数配置。优化结果表明，当椭圆形上均压环参数b=c=92 mm,θ=-60°,椭圆形下均压环参数b=c=85 mm,θ=-102°时，上下均压环的表面场强最大值分别下降了4.8%和6.4 ...

110 kV棒形悬式复合绝缘子绝缘包覆均压环设计与试验研究

Dianci bileiqi, 2021
复合绝缘子安装均压环后减少了高压端和低压端的电弧距离,易受鸟害的影响,发生鸟粪闪络事故。为减少鸟害故障的发生,采用绝缘包覆的方法对普通均压环进行绝缘化改造,首先建立了三维仿真模型,分析了复合绝缘子电场分布规律,然后设计并制作绝缘均压环,通过模拟现场运行条件,测量了复合绝缘子周围的电场分布以及均压环周围放电情况,最后模拟了鸟粪闪络模拟试验,测试了绝缘包覆均压环电气绝缘性能。研究结果表明:绝缘包覆均压环与普通均压环的均压效果基本一致,绝缘包覆层对复合绝缘子沿面电场分布影响较小 ...

Complex and nonlinear climate‐driven changes in freshwater insect communities over 42 years

Conservation Biology, Volume 34, Issue 5, Page 1241-1251, October 2020., 2020
Abstract The ongoing biodiversity crisis becomes evident in the widely observed decline in abundance and diversity of species, profound changes in community structure, and shifts in species’ phenology. Insects are among the most affected groups, with documented decreases in abundance up to 76% in the last 25–30 years in some terrestrial ecosystems ...

Prolonged Exposure and Sertraline Treatments for Posttraumatic Stress Disorder Also Improve Multiple Indicators of Social Functioning

Journal of Traumatic Stress, Volume 33, Issue 4, Page 488-499, August 2020., 2020
Abstract Trauma survivors with posttraumatic stress disorder (PTSD) frequently also suffer from difficulties in social functioning that range across emotional, cognitive, and environmental domains. A detailed evaluation of the differential impacts of effective PTSD treatments on social functioning is needed.

Interfacial Engineering of Sodiophilic Metal Layers on Liquid Alloys for Dendrite‐Free Sodium Metal Anodes

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.

Synergistic Engineering of Amorphous Cathode and Hybrid Electrolyte Toward Stable High‐Voltage Aqueous Zn‐Ion Batteries

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

The Dejudicialization of the German Federal Bureaucracy: An Organizational Perspective on Policy‐Related Knowledge

Review of Policy Research, Volume 43, Issue 3, May 2026.
ABSTRACT Using data from a long‐term survey of senior civil servants (1970–2021), this study investigates the declining share of jurists in federal ministerial departments in Germany. The mechanisms driving this trend and its subsequent effects are discussed from an organizational perspective, highlighting the influence of environmental pressure and ...

Synergistic Regulation of Na+ Solvation Structure and Interfacial Chemistry Enabled by a Bifunctional Sultone Additive for High‐Voltage Sodium Metal Batteries

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Sodium metal batteries (SMBs) are regarded as promising candidates for next‐generation energy storage systems owing to their high theoretical energy density and low cost. However, their practical development is hindered by the instability of the electrode–electrolyte interphase (EEI), particularly under high‐voltage operation.
