Detection of canine external ear canal lesions using artificial intelligence

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 424-432, August 2025.
Background – Early and accurate diagnosis of otitis externa is crucial for correct management yet often can be challenging. Artificial intelligence (AI) is a valuable diagnostic tool in human medicine. Currently, no such tool is available in veterinary dermatology/otology.

触头结构对真空灭弧室开断能力影响的试验研究

open access: yesGaoya dianqi, 1984
真空断路器的灭弧室外形结构,几乎已典型化,而灭弧室中触头的几何形状及触头材料,则相差很大。近几年来,由于触头几何形状设计改变,开断电流有了较大的突破,在实验室中开断能力已达到200kA以上。为了研究触头结构对真空灭弧室的开断能力的影响,我们对几种不同触头结构的真空灭弧室的开断能力 ...

A Difficult Start for the UK Labour Government, But Time Is Still on Their Side

open access: yesWorld Affairs, Volume 188, Issue 3, Fall 2025.
ABSTRACT The newly elected Labour Government in the United Kingdom promised change. However, the first 10 months have been disappointing, characterized by misjudged announcements regarding the Winter Fuel Allowance and Employers' National Insurance contributions. Yet, there is still time to get back on track with welfare reform and create a new welfare

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.

Including the urbanization gradient in people‐centered wildlife conservation in Amazonia

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Conservation policy in the Amazon traditionally focuses on rural areas, overlooking the socioecological roles of urban populations. This oversight can hinder sustainability by neglecting rural–urban connections. We compared the prevalence and quantity of wild meat consumed, bartered, and traded commercially in rural, peri‐urban, and urban ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

模块化混合型直流断路器开断能力影响因素分析

open access: yesGaoya dianqi, 2018
基于半桥子模块拓扑的模块化多电平电压源换流器(HBSM-MMC)和直流断路器构建的柔性直流电网能够实现大规模新能源的并网和消纳,发展前景良好。柔性直流电网技术的发展主要限制于高压直流断路器,因此对高压直流断路器开断过程以及开断能力影响因素的研究十分有必要。文中首先研究了适用于HBSM-MMC柔性直流电网的模块化混合型高压直流断路器运行原理;并在此基础上详细分析了模块化混合型直流断路器开断时间的影响因素;然后研究了直流断路器过电压的影响因素;最后在PSCAD ...

Social science integration at state and federal fish and wildlife organizations in the United States

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Increasingly, conservation professionals and scholars recognize the need for more holistic integration of social science in fish and wildlife management. This call is often framed around the complexity of 21st century conservation challenges and changing societal values toward fish and wildlife and its management.
