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

Gaoya dianqi, 2012 笔者分析了天广直流控制保护系统改造完成后发生的3次双极线路保护动作事件,剖析其中直流线路突变量保护误动作的原因。根据天生桥换流站和广州换流站的实际录波和实际过程,结合厂家给出的突变量保护定值和整定思想,分析导致突变量保护误动作的因素。笔者给出了2个解决方案——降低低电压保护定值和增大突变量保护的动作延时,并经实践验证正确,为以后更好地实施直流控制保护系统国产化改造提供参考。

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Dianci bileiqi, 2016 电涌保护器被广泛应用于低压交流电源系统,用来抑制雷电暂态过电压从而有效保护低压电子设备。但因传统电涌保护器中元器件数量较多、体积较大等缺点,在分析传统电涌保护器的同时对其进行简化,进而提出了一种简化的电路模型。采用电磁暂态仿真软件PSCAD/EMTDC分别对传统的和简化的电涌保护器电路进行雷电暂态响应仿真分析,并对比其仿真结果。此外,组装了两种电涌保护器并实测了保护器的雷电暂态响应。试验和仿真结果表明简化电路也具有较好的保护性能,可取代传统的电涌保护器。

Public Administration, EarlyView.ABSTRACT As the public sector increasingly adopts AI‐powered automated decision systems (ADS), understanding how citizens experience and value ADS use in public decision‐making is both normatively and practically important. Therefore, we examine and compare the effects of seven attributes of public values on citizens' support for ADS adoption in two ...

野生动物学报, 2011 江西省原有鸟类记录480种,对江西武夷山、鄱阳湖等7个代表性自然保护区的鸟类名录进行整理后,7个自然保护区共记录鸟类479种,占江西省鸟类数的91.8%,其中有42种为原江西省记录中未记录的物种。至此江西省共记录有鸟类522种,但有43种在7个自然保护区内没有发现。7个自然保护区记录中具有特殊保护意义的鸟类有283种,占江西省的91.0%。建议在加强鸟类保护调查监测和保护区建设的同时,修订补充江西省重点保护野生动物名录。

Policy Studies Journal, EarlyView.ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...
