Research on Sand Dumping Detection of Harbor Dredging Based on Empirical Mode Decomposition [PDF]
, 2014 港口疏浚工程作业是港口建设的重要组成部分，但是，由于疏浚驳船存在违规倾倒泥沙的现象，导致清理和养护港口航道的成本大幅增加、造成巨大的经济损失和严重的生态坏境破坏。目前普遍采用的GPS定位及在驳船上安装摄像头、吃水线检测装置等监控设备的方法，因其易受人为破坏和环境因素的影响而无法得到满意的应用效果。国内航道管理部门迫切需要一种非接触式的、稳定可靠的监控手段，来有效监管疏浚驳船的操作行为，从而保证疏浚工程作业的质量。 本文根据混浊海水声吸收的原理，提出利用水下通信技术和信号处理技术 ...

Systematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.

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.
