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.

智能科学与技术学报, 2020 污水处理过程入水干扰严重，不确定性强，因而对溶解氧浓度进行实时控制与精确控制比较困难。为了提高溶解氧浓度的控制精度和控制器的鲁棒性，提出一种基于相关熵模糊神经网络（CFNN）的溶解氧浓度在线控制方法。首先，建立了基于跟踪误差相关熵的性能准则，以抑制较大的异常值。其次，基于在线梯度下降算法调整控制器的参数，并分析了系统的稳定性。最后，基于基准仿真 1 号模型（BSM1）进行实验。结果表明，提出的CFNN控制器能够实时精准地跟踪溶解氧浓度，相比其他基于均方误差准则的神经网络控制器 ...

Production of top Quark pair at the large hadron collider(大型强子对撞机中顶夸克对的产生)
Zhejiang Daxue xuebao. Lixue ban, 2018 通过分析质心能量为8 TeV的质子-质子对撞实验，对大型强子对撞机上的ATLAS探测器，测量了顶夸克对产生过程pp→t的归一化微分散射截面，该实验数据对胶子部分子分布函数的确定非常重要.采用蒙特卡罗数值计算程序MadGraph以及CT10NNLO和CT14NNLO部分子分布函数，分别计算此过程的归一化微分散射截面，得到了与ATLAS实验相符的结果.进一步，用ATLAS实验数据和本文的理论计算结果，更新CT14NNLO部分子分布函数.结果显示，顶夸克对归一化微分散射截面对部分子分布函数不敏感 ...

Observation of Spin Splitting in Room‐Temperature Metallic Antiferromagnet CrSb
Advanced Science, Volume 11, Issue 43, November 20, 2024.A substantial antiferromagnetism‐induced momentum‐dependent band splitting is observed in room‐temperature metallic antiferromagnet CrSb. Using high‐resolution angle‐resolved photoemission spectroscopy measurements, clear evolution of band splitting along both out‐of‐plane and in‐plane directions is realized.
