Role of low‐impact‐factor journals in conservation implementation
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Academic review, promotion, and tenure processes place a premium on frequent publication in high‐impact factor (IF) journals. However, conservation often relies on species‐specific information that is unlikely to have the broad appeal needed for high‐IF journals.

International Journal of Applied Linguistics, Volume 35, Issue 1, Page 274-290, February 2025.Abstract Metacognitive regulation refers to learners’ ability to use a repertoire of metacognitive strategies to guide, observe, and manage thoughts, actions, and emotions in learning activities. It has been widely acknowledged as a significant predictor of language learning success, including writing.

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs
Veterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...

Gaoya dianqi, 2020 随着GIS电压等级的升高及应用的普及,现场出现了越来越多的GIS异响振动问题。GIS现场的异响振动有装配不良造成的、也有高频信号入侵引起的,甚至存在随GIS运行方式的不同出现时强时弱的异响振动问题。文中旨在对时强时弱异响振动的成因进行剖析,以从源头上解决防振问题。从理论上分析了空载及负载时GIS导体与壳体间存在的电场力和电磁力,推导出电场力、电磁力与施加电压值、承载电流值及工频频率间的数学表达式。GIS空载运行时导体与壳体间仅有电场力的作用、且电压等级越高电场力越大 ...

Gaoya dianqi, 2019 文中提出了一种气体绝缘组合电器（gas insulated switchgear,GIS）超声波检测异常信号的时频特征计算与诊断方法。首先运用希尔伯特—黄变换（Hilbert-Huang transform,HHT）得到描述超声波信号包络线的时频特征的Hilbert幅值谱。在此基础上,给出了离散条件下Hilbert边际谱与平稳性指数的计算方法,分别表示信号中各频率成分的总强度和平稳性。然后将Hilbert边际谱与平稳性指数结合起来分析,可以直观读取信号的时频特征,进而推断出异常气室的故障原因 ...

Guangtongxin yanjiu, 2017 研究了基于OFDM（正交频分复用）的电力线与可见光融合通信系统中的信道估计技术,通过建立电力线与可见光信道模型,研究了梳状和块状导频结构下的LS（最小二乘）与SVD（奇异值分解）两种估计准则,以及线性插值与基于DFT（离散傅里叶变换）的插值两种内插方法,通过比较发现,块状导频下的SVD结合线性插值是性能较佳的信道估计算法,并且该算法对导频间隔不敏感。

基于ILPSO-LSSVM的GIS设备隔离开关机械异响振动识别方法研究
Gaoya dianqi, 2023 隔离开关正常运行对保证气体绝缘开关GIS(gas insulated equipment)设备安全极为重要。文中针对GIS设备隔离开关机械异响振动识别方法开展研究，采用真型GIS设备平台模拟了隔离开关触头接触不良的5个典型状态：正常接触（148μΩ）、轻微接触不良（221、298μΩ）、严重接触不良（433、550μΩ），检测并分析了GIS设备隔离开关机械振动特性，发现GIS设备正常振动的主频率为100 Hz，振动幅值随电流增大而增大；当隔离开关存在接触不良缺陷时，振动频谱100 Hz振动分量幅值增加 ...
