The link between obesity and insulin resistance among children: Effects of key metabolites 儿童肥胖与胰岛素抵抗之间的联系:关键代谢产物的影响

open access: yesJournal of Diabetes, Volume 15, Issue 12, Page 1020-1028, December 2023., 2023
Highlights Childhood obesity was significantly associated with the increased risk of insulin resistance (IR). There were 12 metabolites co‐associated with childhood obesity and IR, including seven amino acid and five fatty acid metabolites. The combination of body mass index standard deviation score and key metabolites could effectively predict the ...

Identifying socioeconomic and biophysical factors driving forest loss in protected areas

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Protected areas (PAs) are a commonly used strategy to confront forest conversion and biodiversity loss. Although determining drivers of forest loss is central to conservation success, understanding of them is limited by conventional modeling assumptions.

Evaluating the determinants of support for police militarization among officers

open access: yesPolitics &Policy, Volume 51, Issue 4, Page 636-660, August 2023., 2023
Abstract We evaluate the determinants of officer support for their agency participating in the 1033 Program: a program that facilitates the flow of military hardware to local law enforcement agencies. In doing so, we provide insight into why officers demand such equipment, which, in turn, may partially explain patterns of program participation and ...

Development and validation of risk prediction models for large for gestational age infants using logistic regression and two machine learning algorithms 使用Logistic回归和两种机器学习算法开发和验证大于胎龄儿风险预测模型

open access: yesJournal of Diabetes, Volume 15, Issue 4, Page 338-348, April 2023., 2023
Highlights The logistic regression model consisted of seven commonly used clinical indicators (including lipid profile) and gestational diabetes mellitus subtypes, with an area under the curve (AUC) of 0.760 for the training set and 0.748 for the internal validation set.

Modelling past and future land‐use changes from mining, agriculture, industry and biodiversity in a rapidly developing Southeast Asian region 采矿、农业、工业和生物多样性保护影响下东南亚快速发展区域过去和未来土地利用变化模拟

open access: yesIntegrative Conservation, Volume 2, Issue 1, Page 43-61, March 2023., 2023
We apply an integrative perspective to modelling current and future land‐use change in Kuantan, Malaysia, a location with highly biodiverse forests, and also a hotspot of land‐use change. The region is representative of the types of development challenges faced by countries in Southeast Asia, which are also biodiversity hotspots.

PROTOCOL: Critical appraisal of methodological quality and reporting items of systematic reviews with meta‐analysis in evidence‐based social science in China: A systematic review

open access: yesCampbell Systematic Reviews, Volume 18, Issue 4, December 2022., 2022
Abstract This is the protocol for a Campbell systematic review. The objectives are as follows: (1) To evaluate the reporting quality of systematic reviews published in Chinese social science journals against the PRISMA and MOOSE standards; (2) To evaluate the methodology quality of systematic reviews published in Chinese social science journals against

Generalization of threats attributed to large carnivores in areas of high human–wildlife conflict

open access: yesConservation Biology, Volume 36, Issue 5, October 2022., 2022
Abstract Fear‐induced generalization of threats to noninimical stimuli is a behavioral tendency of humans to minimize exposure to potential threats. In human–carnivore conflict zones, people often generalize their fear of predation by obligate carnivores to nonobligate carnivores despite differences in species’ predation rates.

Improving protected area effectiveness through consideration of different human‐pressure baselines

open access: yesConservation Biology, Volume 36, Issue 4, August 2022., 2022
Abstract Previous assessments of the effectiveness of protected areas (PAs) focused primarily on changes in human pressure over time and did not consider the different human‐pressure baselines of PAs, thereby potentially over‐ or underestimating PA effectiveness.

基于最大奇异值能量熵和随机森林的真空快速开关机械故障诊断

open access: yesGaoya dianqi, 2023
针对电磁斥力机构真空快速开关的机械状态监测问题,提出了一种最大奇异值能量熵(energy entropy of maximum singular value,EEMSE)和随机森林的故障诊断方法。首先,在真空快速开关中采集振动信号,对振动信号进行改进S变换得到模矩阵,随后对该矩阵的子矩阵进行奇异值分解,再利用信息熵理论对最大奇异值求熵得到特征向量,最后将特征向量输入随机森林模型进行故障分类和诊断。与不同特征量和分类器比较后的结果表明,文中提出的真空快速开关机械故障诊断方法特征一致性好,模型诊断速度较快 ...

基于深度森林的高压断路器弹簧机构状态识别

open access: yesGaoya dianqi, 2023
系统的安全稳定运行与高压断路器的可靠性密切相关,合闸阶段的行程曲线可以反映出高压断路器的弹簧机构机械状态,是实现状态识别的重要判据,因此基于行程数据的弹簧机构状态辨识具有重要的研究意义。文中对合闸弹簧预压缩量减少10 mm或15 mm、分闸弹簧预压缩量减少10 mm或15 mm、油缓冲器抽油10 mL或30 m L、传动构件卡阻档位1或档位2以及正常状态下9种合闸特性曲线进行了采集,然后基于深度森林(deep forest,DF)算法构建辨识模型,最后将识别结果与主成分—支持向量机、随机森林算法进行对比。
