Testing the QNSE scheme with the modified coefficients of turbulent mixing length scale: Three summer and autumn coastal gale cases study in China(用调整边界层湍流系数的QNSE方案模拟夏秋季沿海大风的应用研究)

Zhejiang Daxue xuebao. Lixue ban, 2018
利用WRF模式，采用YSU、QNSE边界层参数化方案以及调整参数后的QNSE边界层参数化方案(MQNSE),对2009年7月梅雨个例、2015年苏迪罗台风以及2013年10月的近海大风进行了模拟试验，并对模拟结果进行对比检验，着重检验参数调整后的QNSE方案模拟沿海大风效果.研究结果如下：参数调整后的QNSE 边界层参数化方法改进了对沿海风场的模拟效果，尤其是当风速小幅脉动时，参数调整后的QNSE方案较接近于实况风速的波动.通过登陆台风个例模拟试验和对沿海10个岛屿观测站的490个样本统计检验表明 ...

Randomised, Double‐Blinded, Placebo‐Controlled Challenge Test With Single Food Items in Dogs With Atopic Dermatitis and Adverse Food Reactions

Veterinary Dermatology, Volume 37, Issue 2, Page 247-256, April 2026.
ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

Deep Learning–Driven Surface‐Enhanced Raman Scattering–Lateral Flow Immunoassay With Au Nanostars for High‐Accuracy Respiratory Virus Detection

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Contribution of microcosm experiments to conservation science

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

基于模拟负载的特高压换流阀MVU冲击电压试验方法探讨

Gaoya dianqi, 2017
特高压直流换流阀多重阀单元（MVU）冲击电压试验为型式试验的一部分,四重阀的MVU冲击试验具有试验回路大、试品数量多、试验成本高等不足。为解决上述问题,国内外学者研究设计了模拟负载,并提出基于模拟负载的MVU冲击试验方法。文中对采用该方法得到的试验数据进行分析,得出如下结论:基于模拟负载的MVU操作冲击试验科学可靠;基于模拟负载的MVU雷电冲击试验,在阀两侧并联电容可改善模拟负载电压波形;基于模拟负载的MVU冲击电压试验,需进行总试验电压及模拟负载电压的差值运算,防止阀承受过高电压导致晶闸管级损坏 ...
