Wildlife Letters, EarlyView.This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Wildlife Letters, EarlyView.By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐

, 1994 加强劳动保护与职工安全意识中国科学院心理研究所博士研究生林泽炎工矿企业实施劳动保护，在某种意义上可以说是为了唤起并强化广大职工的安全意识。调查得知，许多工矿企业及安全管理部门制定劳动保护措施，一般是根据事故造成的后果制定的，很少顾及职工本身的生理、心..

Guangtongxin yanjiu, 2003 给出了 ADMH算法在无保护、有保护、1∶ 1保护 （保护波长不变和可变 ）、1∶ 1保护且调整 （保护波长不变和可变 ）等 5种不同保护策略下的应用 .通过计算机模拟仿真 ,得到了阻塞率在不同连接到达率时的数据 .结果表明 ,有保护会大大增加连接阻塞率 ,保护波长可变在复用波长数大时效果明显 ,保护调整大约能降低阻塞率 5 % .

Wildlife Letters, EarlyView.We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

, 2015 1振动对文物影响问题的提出 振动是自然界常见的一种物理现象，现代社会的生产活动和现代人们的生活活动都在产生振动，如轨道交通运行、爆破、振动冲击强夯加固地基、锤击破碎加工石料等。人们一方面要利用可能产生振动作用的功效，同时又在受到振动的伤害，如乘坐汽车跑的快了，却要遭受汽车颠簸振动的危害。在能高效达到一定施工目的同时，振动可能危及相邻近建筑物的安全和影响人们的正常生活。《中华人民共和国环境保护法》明确定义振动是一种公害。因此防止震动造成损害是许多工程建设设计和施工中要关心的重要问题 ...

全球能源互联网, 2019 电力巡检无人机提供大量的巡检图像，但由于电力设备故障稀少，其中只有少量的设备缺陷故障图像可供使用。为了提高设备缺陷故障识别精度并减少训练过拟合问题，首先介绍了基于迁移学习的小样本电力巡检图像处理方法，通过图像裁剪、翻转、旋转等数据增强技术对小样本图像进行扩充，同时采用生成对抗网络（GAN）来扩充基础样本；并使用迁移学习技术，将基于大规模图像数据的预训练深度卷积模型进行定制，调整该神经网络模型的输入层和最后两层参数，并对超参进行调优。实验结果表明，巡检设备故障（如导线断股和绝缘子串脱落等）准确匹配度近95%

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
