Evolution of research on global amphibian declines
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Clip Voice: Misogyny and the Renegotiation of a Gendered Vocal Style in Chinese Digital Discourse
ABSTRACT The participatory culture of social media allows women's voices to be heard but also parodied and policed. On Chinese social media platforms, where performers rapidly adopt and transform vocal trends for engagement, discourse on gendered vocal styles has proliferated.

ABSTRACT Objectives Ultrasound is the first‐line imaging modality of the pelvis in the pediatric and adolescent gynecology (PAG) population. Ultrasound findings in pre‐ and postpubertal PAG patients differ from those in adults. Diagnostic models for adnexal pathology have not been validated in this cohort.

Lack of species information complicates understanding climate change vulnerability, but life history traits can be proxies for missing information. In the north‐central United States, useful traits for discriminating vulnerability of amphibians include range size, clutch size, diel activity patterns, and habitat breadth.

Abstract Eradicating invasive predators from islands can result in substantial recovery of seabirds, but the mechanisms that drive population changes remain poorly understood. Meta‐analyses have recently revealed that immigration is surprisingly important to the recovery of philopatric seabirds, but it is not known whether dispersal and philopatry ...

包封受潮是导致干式空心电抗器匝间绝缘失效的重要诱因,文中通过对故障退运电抗器的解剖分析以及匝间绝缘材料的湿热老化试验,研究包封受潮对干式空心电抗器匝间绝缘的破坏作用。首先,解剖了一台南方地区故障退运的电抗器,利用扫描电镜、傅里叶红外光谱仪、断裂拉伸试验等对样品的理化性能进行分析,推断受潮后包封内部绝缘的变化过程;然后,进一步对作为匝间绝缘材料的PET聚酯薄膜进行了湿热老化试验,研究了其在不同湿度老化条件下击穿场强、断裂伸长率的变化。研究表明:干式空心电抗器有可能严重受潮 ...

Abstract Mangrove forest is an ecosystem‐based solution for disaster risk reduction in the Philippines, but its historical deforestation has hampered its capacity to protect coastal communities. With the increasing occurrence of storm surge in the Philippines, mangrove reforestation projects have received renewed attention, but many have failed ...

绝缘子表面污秽电导率对污闪预警具有重要作用,然而绝缘子表面污秽分布不均,其形成的微小电容对表面电导率的检测产生较大影响。为克服该影响,文中研制了基于相角差的绝缘子表面污秽电导率检测系统,详细介绍了系统检测原理以及系统关键部分的设计和仿真,并在实验室进行了污秽受潮试验,分析了污秽表面电导率随受潮时间的变化规律。结果表明:污秽干燥时,表面电导率很小;随着受潮的进行,表面电导率不断增大;污秽饱和受潮时,表面电导率达到最大;污秽过饱和受潮、流失时,表面电导率不断减小。因此,可将污秽受潮过程分为3个区段,受潮区 ...
