Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Automatic vibration fault detection of coal mine explosion-proof electrical equipment based on One-Class Support Vector Machine [PDF]
The vibration generated by explosion-proof electrical equipment in coal mines during operation can compromise its mechanical integrity, leading to fastener loosening, component wear, and changes in the structure and vibration modes of the equipment. This

Gaoya dianqi, 2020 线路的信道模型是决定中压载波通信性能的关键因素,具有公共屏蔽的三芯中压电缆形成的信道复杂,互相耦合,传统解析计算困难且不易测量,文章首先利用模态分解方法简化三芯电缆通信信道,简化后的信道之间的信号完全解耦,有利于测量及分析;其次,通过有限元分析方法对三芯电缆的分布参数进行计算,基于文中提出的模态分解方法对计算结果进行变换,得到简化后的三芯电缆信道传输线参数。将得到的结果与实测结果对比,验证了模态分解方法以及分布参数有限元计算的正确性。
