Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

open access: yesConservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

限压型低压电涌保护器级间能量配合方式的仿真研究

open access: yesDianci bileiqi, 2013
为了研究限压型低压电涌保护器级间能量配合的保护方式,参考IEEE工作组提出的MOV冲击等效电路模型,利用EMTP电磁暂态仿真软件来模拟在8/20μs、10/350μs两种冲击电流波作用下两级SPD最有效的配合保护方式。仿真结果得出在8/20μs冲击电流波作用下采用高-低配合的方式,而在10/350μs冲击电流波作用下采用低-高配合的方式是最为合理的。为敏感电子设备的防雷保护提供了参考依据。

Emerging applications of large language models in ecology and conservation science

open access: yesConservation 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

低压配电系统电涌保护器保护模式研究

open access: yesDianci bileiqi, 2017
为了有效利用电涌保护器对低压配电系统进行雷电过电压防护,需要对电涌保护器保护模式进行研究。利用EMTP软件搭建1.2/50-8/20μs组合波和0.5μs-100k Hz标准振荡波发生电路,同时采用IEEE氧化锌压敏电阻模型进行仿真冲击。分析TN-C-S配电系统中不同电涌保护器保护模式的防护效果。最后讨论电涌保护器接地电阻阻值对线间电位差影响。仿真结果表明:仅在L线与N线或L线与PE线间安装SPD,不能够有效保护负载设备;在L线与N线、N线与PE线间安装SPD或三线间均安装SPD时,防护效果较好 ...

On Protecting Pattern under Special Law for Traditional Knowledge [PDF]

open access: yes, 2006
传统知识保护问题,是这几年知识产权领域研究的热点问题。但对于该采取何种模式保护传统知识,众说纷纭。本文在对传统知识进行界定的基础上,对已有四种保护模式的优势与劣势进行分析比较,认为专门法保护模式为最优模式。并通过对1992年《生物多样性公约》及各国立法确立的遗传资源保护模式进行分析探讨,对我国传统知识专门法保护模式进行机制设计。除了引言和结论外,本文共分为四章:第一章对传统知识进行界定,将传统知识限定为产业领域内的技术性知识和经验。其次,介绍传统知识具备的特点,为下面章节保护模式的选择与设计奠定基础 ...

Insights for conservation from the Ecological Knowledge Games project

open access: yesConservation 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 ...

Thinking About the Problems of Customs Role in the Protection of Intellectual Property Rights [PDF]

open access: yes, 2017
当今国际贸易越发成熟,技术与知识交流也愈加频繁,国际贸易中侵权货物的存在不仅损害知识产权权利人的合法利益,而且破坏了现有的国际贸易秩序,因此知识产权侵权问题逐渐成为学术界关注的焦点。90年代,中美知识产权的第一次谈判开启了我国对知识产权海关保护理论的研究,成果颇丰。与此同时,海关对进出口环节中知识产权的保护水平也逐步提升,包括海关查处的案件以及与地方公安机关等部门联合协作的各类案件,打击侵犯知识产权的成效也日益显著。但目前,知识产权海关保护中也存在海关角色定位不清的问题 ...

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

open access: yesPolicy 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 ...
