Wildlife Letters, Volume 1, Issue 2, Page 71-78, June 2023., 2023 Oaks are often removed as part of longleaf pine restoration; however, it is unclear if oak patches produce important resources for native wildlife. We studied wildlife use of the transition between longleaf pine woodlands and hardwood hammocks. We found these areas support a variety of wildlife species and future management and restoration of longleaf ...

Conservation Biology, Volume 35, Issue 6, Page 1715-1724, December 2021., 2021 Abstract Despite its successes, the U.S. Endangered Species Act (ESA) has proven challenging to implement due to funding limitations, workload backlog, and other problems. As threats to species survival intensify and as more species come under threat, the need for the ESA and similar conservation laws and policies in other countries to function ...

Journal of Advanced Nursing, Volume 77, Issue 4, Page 1825-1838, April 2021., 2021 Abstract Aim To analyse the interactions of associated factors with post stroke fatigue (PSF) after discharge home and determine the predictors of PSF and their impact on stroke survivors. Design A prospective observational study. Methods A total of 94 patients with acute stroke were recruited between May 2019 ‐July 2020. The main outcomes were fatigue,

智能科学与技术学报, 2023 传统的物料传输设备存在工作方式单一、传输路径柔性调整困难等问题，智能化物料传输系统已逐渐成为物流传输领域的研究热点之一。面向模块化物料传输平台，提出了一种基于A*与动态窗口法的路径规划算法，以期通过柔性调整物料传输路径提高传输过程中的避障能力。在全局路径规划中通过改进A*权值函数，融合Bezier曲线与矩阵干涉理论，实现了传输路径的平滑与静态避障；通过引入动态窗口法并提取全局路径关键点作为过渡点对传输目标进行局部路径指引，在避免路径陷入局部最优的同时，实现了传输目标的动态避障。研究结果表明，基于A ...

Shuitu Baochi Xuebao, 2002 生物圈保护区通常从内向外划分为核心区、缓冲区和过渡区 (或者外向空间扩张过渡区 ) ;核心区与缓冲区必须明确划定边界 ;过渡区不必划定外围边界 ,被赋予外向空间扩张性。博格达生物圈保护区从内向外划分为过渡区、缓冲区和核心区 ,定义为逆序组织模式。缓冲区边界为内部过渡区设置了空间边界 ,使常规组织模式外围过渡区的外向空间连续扩张性失去意义 ,内部过渡区的空间发展只能采取向内的内部加密方式和向外的跨越空间方式。研究表明 ,内部过渡区跨越外围缓冲区限制的新途径是建立岛国经济外向发展模式 ;经营过渡区要遵循生态

Ecology and Evolution, Volume 16, Issue 5, May 2026.This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Magnesium (Mg)‐based composites are regarded as promising lightweight materials with significant potential for structural applications. The structure–property relationships of bionic Mg‐based composites remain unclear. Herein, three honeycomb‐like Mg‐Fe composites are fabricated to uncover the underlying strengthening mechanisms.

, 2008 利用控制加热电压和加热面平均温度两种方法，实验研究了常压（0．1MPa）、室温（16℃）条件下除气后的R113在直径60μm细铂丝表面的池沸腾传热现象，观测了单相对流、核态沸腾、双模态过渡沸腾和膜态沸腾4种传热模式中的汽相分布及其传热特征，发现充分发展的核态沸腾传热曲线、膜态沸腾传热曲线及临界热流的数值分别与文献中常用关联式的预测一致，而核态沸腾和膜态沸腾共存的稳定双模态过渡沸腾曲线被一极小值点分为两个连续分支，邻近膜态沸腾的右支上热流与过热度成正比，而邻近核态沸腾的左支上热流则随过热度增长而下降 ...
