野生动物学报, 2022 2020年全年，太原动物园对8只群养猎豹（Acinonyx jubatus）进行了系统的正强化训练。依据群养个体相容性，将每2只猎豹个体分隔在1个笼舍中，仅由1名训练员就可以在40 min内完成对8只猎豹的全部训练内容，并可以有效减少训练时的个体干扰及攻击行为。对猎豹的训练项目、行为要求、使用口令、训练进度、训练目的等内容进行了总结，并讨论了群养个体在训练时的空间分隔、时间安排、如何减少食物争抢等训练要点，为圈养猎豹及其他物种的群养动物训练提供参考借鉴。

Dizhen xuebao, 2022 为了探索地震加速度时程记录的震级信息，训练卷积神经网络基于地震震级大小对地震记录进行分类，将K-NET和KiK-net中将近12万个地震记录作为样本，对其进行信息筛选和归一化，之后将地震加速度时程记录用作输入，训练卷积神经网络模型以M5.5为分类界限来区分大震和小震。结果显示，在训练集中基于该模型的分类准确率为93.6％，在测试集中的准确率为92.3％，具有良好的分类效果，这表明大震记录与小震记录之间存在一些根本的区别，即可通过地震动加速度时程记录获取一定的震级信息。

Zhongshan Daxue xuebao. Yixue kexue ban, 2022 目的为了获得造模时间更短且症状维持时间更长的慢性强迫症小鼠模型，我们尝试对已有的喹吡罗诱导的慢性强迫症小鼠模型的造模方式进行优化。方法将22只小鼠随机分成实验组（n=11）和对照组（n=11），分别在其颈后皮下注射0.75 mg/kg的喹吡罗溶液或等量的生理盐水后放入强迫行为训练装置中训练，连续重复19 d，并记录两组小鼠训练期间的饮水行为及饮水量，评估喹吡罗对小鼠行为的影响。训练结束后通过进行旷场实验、高架十字迷宫实验、新物体识别等行为学实验，评估小鼠的焦虑状态和认知能力 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Developing advanced electrocatalysts for urea synthesis is pivotal to alleviating environmental burdens as well as advancing sustainability in the industrial and agricultural sectors, yet untargeted catalyst screening still suffers from the notorious drawbacks of being time‐consuming, labor‐intensive, and inefficient.

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Veterinary Dermatology, Volume 37, Issue 2, Page 236-246, April 2026.Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 4, December 2025.ABSTRACT Research examining the complexities and operational structures of civil–military coordination within large‐scale disaster response frameworks in Canada remains scant. This study addresses this gap by critically evaluating existing civil–military coordination mechanisms, identifying systemic deficiencies, and proposing evidence‐based strategic ...

野生动物学报, 2020 行为训练做一种丰容手段，在圈养野生动物管理中正逐渐运用。其目的是通过正强化刺激，让动物学会指令配合动物管理，从而减少胁迫。然而目前并没有合适的生理指标来评价训练对动物的影响。本实验对象是杭州动物园饲养的2只黑叶猴，通过对其中1只“大杭”个体进行持续30 d的正强化行为训练，训练目标为肌肉注射。通过GC-MS代谢组手段测定粪便所有代谢产物。模型显示，行为训练后大杭粪便代谢组与训练前具有显著的区别（PLS-DA：R2y=0.951，Q2=0.502；（O）PLS-DA：R2y=0.95，Q2=0.454 ...
