Conservation Biology, Volume 39, Issue 3, June 2025.Abstract Successful long‐term conservation relies on strategic planning for pragmatic actions to mitigate threats. Prioritizing actions and areas to support conservation goals in the most cost‐effective scenario becomes crucial in resource‐limited environments. However, planning and management can be challenging in data‐limited contexts.

Kongjian kexue xuebao, 2023 极光受太阳风驱动的地磁亚暴等大尺度动力学影响，其形态及演化因不同的太阳风-磁层-电离层耦合作用可能表现不同。目前，极光卵及其形态的归类大多依据极光演化理论作主观定性分析，没有明确的分类标准，故难以借助统计分析方法和有监督分类模型开展客观定量研究。建立了基于深度表征学习的紫外极光卵图像聚类模型（MoCo-GMM），并利用空间环境参数设计了评估模型物理合理性的方法，在大规模POLAR卫星紫外极光卵图像数据上进行了实验，聚类结果不仅具有良好的簇内凝聚性和簇间分散性，且具备一定的物理可解释性 ...

Forest citizens and people‐centered conservation in the Brazilian Amazon
Conservation Biology, Volume 39, Issue 3, June 2025.Abstract Demands for territorial recognition are foundational to the claiming of rights by forest‐proximate people who attempt to conserve their forests. The rights of these often‐marginalized populations have been largely overlooked by conservationists, yet they are central to achieving people‐centered conservation. We further developed the concept of

DIAGNOSIS of FLOW CONTROL VALVE USING WAVELET PACKET [PDF]
, 2011 提出了一种利用小波包检测调速阀故障信号的方法。通过小波的小波包分析将信号按一定的尺度进行划分,不同频率的信号被划分到不同的频段中。由经过预处理的信号经过小波包分解与重构后,可以得到小波包重构图,由图中可以获得故障产生的时间点和频率,再对故障的严重程度进行了量化分析。实验结果表明用小波包理论进行故障检测是可行的。We propose the method of flow control valve fault diagnosis employing wavelet packet analysis.We ...

Solid in shape, shattered in practice? The ‘sentencing pyramid’ in China
Journal of Law and Society, Volume 52, Issue 2, Page 292-314, June 2025.Abstract In this article, I use a structural‐functionalist analysis to explain how the sentencing process in the People's Republic of China has morphed into what I call the ‘sentencing pyramid’, with largely discrete and separate praxis across various legal apparatuses. The base of this hierarchical composition encompasses a vast number of infractions,

Guangtongxin yanjiu, 2012 新型相位调制格式技术能够有效地减少光传输损伤,是光传输系统中的重要技术。从理论上分析了光MDPSK（M进制差分相移键控）的调制解调原理,构建了通用的调制解调结构,并首次推导出MDPSK的通式和解调公式,最后以基于CSRZ（载波抑制归零,占空比为67%）码的DQPSK（差分正交相移键控）、8DPSK（3阶差分相移键控）和16DPSK（4阶差分相移键控）为例,用MATLAB软件仿真得到了其调制后的频谱图和解调后的眼图。仿真结果表明,随着级数的增加,MDPSK调制格式的频谱宽度会逐渐变窄 ...

Dreaming Ubuntu: Jungian Studies, Forgiveness, and Jung’s Recalcitrant Fourth
Journal of Analytical Psychology, Volume 70, Issue 2, Page 235-256, April 2025.Abstract Jung’s recalcitrant fourth comes in from a place of opposition, demanding that what has been neglected be considered. It is in the spirit of the fourth that the author examines the use of Ubuntu in Jungian literature, cautioning against a decontextualized appropriation of the notion that overlooks its diverse interpretations and usages ...

Improvement on Performance Management System for A Mall [PDF]
, 2017 近几年新兴经济的发展和外部市场竞争的日趋激烈，对企业的适应能力提出了更高的要求，很多企业在产业转型升级时遭遇重重困难和危机，无法随着市场变化而制定与之匹配的战略，从而被社会所淘汰。绩效管理，作为实现企业战略目标的有效工具，不仅反映了企业对竞争环境变化的适应能力，更是个人与组织实现共赢的关键纽带。这个工具使用恰当，能让员工主动积极地开展工作，从而输出组织期望的结果；使用不当，也容易导致组织内不必要的纷争，大大消耗组织内部资源。因此，绩效管理的有效实施是企业增强核心竞争力的重要举措 ...

A social network analysis of an epistemic community studying neoliberal conservation
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Researchers typically operate in epistemic communities: groups that share common approaches to research agendas and sociopolitical action and define areas of debate. Although productive in their own spheres, a lack of understanding among these communities can undermine scientific progress. Thus, analyzing epistemic communities is important for
