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 ...

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Ultrathin sodium (Na) metal anodes (< 40 μm) with superior electrochemical performance are essential in developing high‐energy‐density sodium metal batteries (SMBs). Nonetheless, Metallic Na's poor processability hinders its practical application.

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

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.

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

, 2003 当环境气体不具备辐射特性时(例如环境气体为O2-N2),在较小的环境压力下,火焰向燃料表面的热传导是火焰传播的主要驱动力.但随着环境压力的增大,火焰传播速度越来越大,火焰对燃料表面的热辐射逐渐成为火焰传播的主要驱动力之一.当环境气体具有较强的辐射特性时(例如环境气体为O2-CO2),在较小的环境压力下,火焰前沿环境气体的辐射再吸收将强化火焰对燃料表面的传热、热辐射和热传导在火焰传播机理中均起重要作用.随着环境压力的增大,氧气向火焰的扩散加强,燃烧反应加剧,火焰传播加速.当环境压力大于一定值时 ...
