China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

He jishu重离子碰撞实验结合输运模型模拟是提取核物质性质信息的重要手段之一。贝叶斯分析是一种能够从实验数据与理论计算的比较中提取信息的统计方法，因此得到广泛应用。在此过程中，通常需借助马尔可夫链蒙特卡罗方法在参数空间中进行采样，并随后开展输运模型模拟计算。然而，由于输运模型的计算复杂且耗时较长，为提高效率，可通过机器学习算法训练一个输运模型仿真器。本文采用高斯过程、多任务神经网络和随机森林三种机器学习算法，对极端相对论量子分子动力学（Ultra-relativistic Quantum Molecular ...

Landscape‐scale predictions of future grassland conversion to cropland or development
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Grassland conservation planning often focuses on high‐risk landscapes, but many grassland conversion models are not designed to optimize conservation planning because they lack multidimensional risk assessments and are misaligned with ecological and conservation delivery scales.

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 768-775, December 2024.Abstract Objective Lower urinary tract obstruction (LUTO) is a chronic condition with a spectrum of outcomes. It is usually suspected prenatally based on ultrasound features (USFs). Given the unknown postnatal trajectory and the potential for significant morbidity and mortality, many families choose termination of pregnancy (TOP), often based on USFs ...

Gaoya dianqi, 2019 高压断路器是电力系统的核心设备,其稳定可靠运行具有重要意义。高压断路器分合闸电流曲线能够很大程度上反映高压断路器分合闸机构的运行状态,因此文中研究了在几种典型故障条件下,断路器分合闸线圈电流的变化。随机森林算法由于算法实现过程中的两次随机过程,使得算法过拟合风险大大降低,模型泛化能力大大增强。提出了使用随机森林算法识别故障电流曲线,取得了很好的效果。
