Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Methods in Ecology and Evolution, EarlyView.Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

Conservation Biology, EarlyView.Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Research and Design of Data Warehouse Model in Bank Based on Teradata [PDF]
, 2015 企业数据仓库的建立对于企业管理具有重要的意义。不同企业须根据其自身特点和现实环境来选择建设数据仓库的路线和方法。 企业级数据仓库发展至今，已经进入一个全面发展阶段。以银行业的企业级数据仓库为例，一个成熟的企业级数据仓库需要具备至少海量数据存储能力(PB级)、数据模型能力(数据按业务主题进行归类如：客户、帐户、会计、交易明细）、大数据量分区能力、大批量处理的计算能力、数据质量的控制能力、高并发处理能力、报表数据存储能力和非结构化数据管理能力等特点。 本文着眼于数据仓库数据模型的研究 ...

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

The redesign research of neighborhoods space in contemporary urban community [PDF]
, 2016 居住社区是构成城市生活的最关键要素，是与我们每个人的日常活动紧密相连的重要场所，它影响着我们的生活方式与习惯。在当代中国城市发展的大环境下，中国居住社区的开发建设形成了特定的小区模式，空间活力逐渐丧失，在邻里空间中产生出各种的问题和矛盾。 本文从这样的现象入手，展开了对社区邻里空间的再设计研究。该研究主要包括三个部分。首先，本文分析了中国当代城市居住社区邻里空间的三个主要模式：“大街区”、“大院式”以及“建筑点状分布”，并追根溯源分别探寻了这些特征的形成原因以及演变过程。其次 ...

Using incentive payments to promote human–carnivore coexistence
Conservation 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

Jianzhu Gangjiegou Jinzhan, 2002 本文提出了实际工程结构的非线性理论设计和分析方法(NIDA),并以澳门回归纪念馆的设计为例,展示了本方法的优越性。在设计过程中,设计者无需假设K系数和有效长度,在结构分析完成后便可迅速完成设计,因此本文提出的方法既经济又便利。尽管对于钢框架在往复荷载及动力荷载作用下的弹塑性大位移分析已经非常成熟,但本文的方法开创了结构的非线性分析及设计的新纪元 ...

Numerical Simulation and Performance Analysis of a Scramjet Based on Three Dimensional Design [PDF]
, 2015 本文以超燃冲压发动机为研究对象，将其中的各部件置于整个发动机的大环境下进行了设计与性能分析。 以流线追踪三维Busemann型面作为进气道，研究了其不启动时的流场特征以及非设计点下的性能。随后将该进气道与隔离段模型相结合进行了数值模拟，结果表明增加隔离段长度可提升极限反压，但长度越长，反压比提升的幅度越小；进气道来流的影响使隔离段在反压作用下的流场呈现不均匀性，反压越高，不均匀性越强，进气道所受的压阻也越大。 在燃烧室设计过程中，以均匀来流为条件分别考察了边界层厚度、狭缝抽吸 ...
