Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Jianzhu Gangjiegou Jinzhan, 2020 以某两栋办公单体间的长悬臂钢连廊为原型,考虑沿钢连廊长度方向的脉动风速非完全相关性,采用谐波叠加法模拟风速时程,并基于准定常假定进行钢连廊的风振时域分析,得到了结构的风振响应和杆件内力。研究表明:由于该钢连廊的特殊体型,在考虑脉动风速水平向空间相关性后,悬挑端的加速度响应增大明显,并产生了扭转振动;钢连廊的风振系数,尤其是长悬挑部分的风振系数增大效应明显;部分构件的内力增幅明显。因此,在长悬臂钢连廊设计中应考虑风速水平空间相关性对风致效应的影响。

Striking a balance: Stakeholder perceptions of risk in horse racing
Equine Veterinary Journal, Volume 58, Issue 3, Page 814-823, May 2026.Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

Dianci bileiqi, 1989 介绍了四种压敏电阻试样在波前1ns左右、脉宽10～100ns极陡脉冲作用下的电流响应和电压响应特性.试验表明,在上述极陡波作用下,电流响应由峰值为Im的容性电流开始,以后转为平稳的阻性电流Is.Im及Is随外施电压u0增加而增加,但增加情况随试样而异.电压响应的前部存在"过冲",随后过渡至平坦的残压Us.过冲出现时间随u0增加而前移,峰值Up变化也跟试样有关.并指出,压敏电阻的"压敏"特性有一个时间过程,它与外施电压的幅值、陡度有关,也与试样有关 ...

Narrative formatting, chronotopic orderings, and moralization in ex‐gay stories
Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.Abstract Formatted stories rely on spatiotemporal cues to evoke recognizability through linearity, which prescribes a particular template for meaning‐making. This article examines stories narrated by ex‐gay members of a Christian organization in Singapore and considers how chronotopes within the stories are ordered to regiment ways of feeling for ...

Gaoya dianqi, 2019 离线时间长短严重影响动车组受流质量,目前离线时间的划分主要根据运行管理经验,尚无理论分析。基于现场测试数据和MATLAB仿真软件,建立了包含弓网离线电弧和列车牵引变流器的仿真分析模型,分析了弓网离线时的过电压与谐波,以及离线对牵引变流器直流侧电压的影响。结果表明:弓网离线和恢复过程均有约1.3倍的过电压产生,并伴随有大量的谐波反馈到接触网上;牵引变流器直流侧压降速度随列车行驶速度的增加而呈指数增大,250 km/h以上行驶速度时1 000 V压降所需时间已经下降到100 ms以内;相同离线时间下 ...
