, 2022 为研究浮式风力机尾迹在平台运动下的演化特征和机理，本文通过线性稳定性分析和大涡模拟方法，分析了浮式风力机在纵荡、横荡和艏摇三种形式下作简谐运动时的尾迹。利用线性稳定性理论，用周向波数表示了不同运动形式引起的尾迹扰动，预测了尾迹在轴对称和非轴对称两种理想扰动下的敏感频率。稳定性分析表明：当纵荡运动的无量纲频率在0.3≤St≤0.5时最易引发尾迹失稳；横荡和艏摇运动的最敏感频率在0.2≤St≤0.4范围内；在三种运动形式下，低频（St≤0.1）和高频（St≥1.0）扰动均不会明显增长。随后 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil salinization and alkalization often suppress microbial functional activity, triggering negative feedback loops in microbial metabolism, degrading nutrients and agricultural productivity.

International Journal of Urban and Regional Research, EarlyView.Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Pest‐preservation paradox among insects
Conservation Biology, EarlyView.The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Gaoya dianqi, 2023 交流电场下超疏水涂层表面液滴的滑动和凝并特性对其污闪特性具有重要影响，为了表征超疏水涂层表面液滴的运动特性，以环氧树脂板为基底利用喷涂法制备了超疏水涂层，测量了均匀电场下超疏水涂层表面不同体积液滴的临界运动场强，并利用基于图像的目标跟踪方法绘制了不同体积液滴的运动轨迹；最后通过仿真计算和理论推导，分析了交流电场下液滴运动机理以及体积对液滴临界运动场强和运动速度的影响。结果表明：液滴体积对其临界运动场强的表现出明显的“体积效应”，0～100μL液滴的临界运动场强在体积为40μL出现一极小值 ...

Early outcomes of England's new biodiversity offset market
Conservation Biology, EarlyView.Abstract Nature markets are being operationalized as a tool to address the biodiversity finance gap and achieve global biodiversity targets. However, there is limited understanding of how the outcomes of these markets align with biodiversity targets.

Zhongguo tingli yuyan kangfu kexue zazhi, 2023 注意缺陷多动障碍（attention deficit hyperactivity disorder， ADHD）是一种常见的慢性神经发育障碍。目前针对ADHD的治疗方法有药物治疗和非药物治疗两种。运动处方作为系统性、实证有效、具有良好前景的治疗方式，已被越来越多的研究者关注。对ADHD儿童运动处方的效果评估主要依据标准化测评量表、神经心理学测试和实验室仪器。在运动处方的要素中，运动类型对改善效果没有显著影响，只需符合各年龄段儿童的运动发育规律即可，而运动的强度、持续时间和频率是运动处方能否取得效果的关键。
