Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves

open access: yesConservation Biology, EarlyView.
Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.

基于Bragg衍射的多频声光衍射效应研究

open access: yesGuangtongxin yanjiu, 2009
文章首先介绍多频声光衍射的原理,然后推导Bragg声光介质的声光衍射耦合波方程,并结合该声光波矢量的分析,定量和定性地讨论了衍射效率、波矢量失配和三阶互调等多频衍射效应。实验表明,各种效应都能很好地与Bragg理论极限相吻合。

Using incentive payments to promote human–carnivore coexistence

open access: yesConservation Biology, EarlyView.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

考虑土壤电离的垂直接地极冲击散流性能分析

open access: yesDianci bileiqi, 2015
准确计算接地装置的冲击散流性能以及输电线路接地极动态冲击特性是优化接地网设计的基础。为了得到垂直接地极的散流特性以及各种因素对垂直接地极散流特性的影响,本文提出基于电磁场的有限元分析方法,对垂直接地极冲击散流特性的动态物理过程进行建模和仿真,在此基础上分析了垂直接地极的冲击散流特性;并进行了垂直接地极的模拟实验,通过对比验证了方法的正确性。结果表明,垂直接地极的散流具有明显的末端效应。

Striking a Balance: Stakeholder Perceptions of Risk in Horse Racing

open access: yesEquine Veterinary Journal, EarlyView.
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).

SF6高压设备电场均匀程度与绝缘水平的统计学分析

open access: yesGaoya dianqi, 2017
SF6广泛的应用于高压设备,其绝缘性能在稍不均匀电场中为空气的3倍,而在极不均匀电场中则接近空气的绝缘性能。因此如何合理设计电极形状,尽量避免极不均匀电场的存在,充分发挥SF6气体在绝缘方面的优良性能,在高压产品的设计中尤为重要。文中从基础电极形状设计入手,应用统计学的原理及方法,分析在高压设备中常见电极形状的设计和改进措施,结果表明:选择合理的设计及改进措施,可以有效地提高SF6高压设备绝缘水平。

A Novel Topical Emollient Plus for Canine Atopic Dermatitis: A Clinical Trial Assessing Efficacy and User Acceptance

open access: yesVeterinary Dermatology, EarlyView.
Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Efficacy of Der f 2/Zen 1‐LAMP1 Plasmid‐Based Vaccine Immunotherapy in Dogs With Atopic Dermatitis: A Proof‐of‐Concept Study

open access: yesVeterinary Dermatology, EarlyView.
Background: DNA‐based vaccination rapidly induces strong cellular and humoral immune responses, which may be enhanced by inclusion of lysosomal‐associated membrane protein‐1 (LAMP). Objectives: This proof‐of‐concept study evaluated the efficacy and safety of a Der f 2/Zen 1‐LAMP‐based DNA vaccine immunotherapy in client‐owned dogs with nonseasonal AD ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

极性反转试验中,±800kV换流变压器套管尾部的电场分布研究

open access: yesDianci bileiqi, 2009
±800 kV换流变压器出线套管,是一个结构复杂的绝缘系统。在试验与运行中,套管要承受不同形式电压的作用。特别在直流极性反转的情况下,套管尾部结构复杂,电场十分集中,易发生油中闪络或击穿放电,严重威胁特高压换流变压器的安全运行。应用有限元法,仿真计算了±800 kV换流变压器出线套管尾部的电场分布,计算结果表明:在极性反转试验中,套管尾部电场分布不均匀,且不同时刻、套管尾部电场分布及各关键位置的场强变化呈现线性特性。进一步分析得知:在套管设计中,不仅要考虑正负极性反转试验电压下的稳态电场分布 ...
