Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

, 2023 近年来电池储能以其响应速度快、能量密度高等优点，在电力系统中发挥重要作用。为满足实际应用的要求，电池储能系统需要将电池或电池组并联从而达到较高的可用容量，但并联电池在实际中受内阻、容量、荷电状态 （SOC）等影响将出现电流不平衡现象，一定程度上制约了电池充放电电流和使用条件，影响了电池性能。针对并联电池组支路电流采集过程繁琐且状态估计复杂的情况，以电池的二阶等效电路为基础，结合回路电流法建立了并联电池组的仿真模型。模型能够根据锂电池的性能参数及状态方程实现并联支路电流的计算，进而估计并联电池组的状态 ...

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to
