High Voltage, EarlyView.ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)

Integrative Zoology, EarlyView.This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

Viewpoint: Optimising Cancer Treatment to Reduce Its Environmental Impact
Journal of Medical Imaging and Radiation Oncology, EarlyView.ABSTRACT It is widely accepted that treatment and care for patients with cancer must and should happen, as it is what everyone would want for themselves and their loved ones. Everyone wants the best possible care, but climate change and the extreme weather that it causes are increasingly affecting everyone including patients in negative ways.

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis
Acta Ophthalmologica, EarlyView.Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Boreas, EarlyView.We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

Gaoya dianqi, 2010 机械式SF6密度控制器在运行中时有误报警现象。对国内外已使用过的4类SF6密度控制器的不同结构、SF6温度、环温以及使用处海拔高度对监控特性的影响进行了分析。得出,Ⅳ型国产密度控制器质量稳定、监控精度较好;目前使用的SF6密度控制器对GCB/GIS的SF6密度具有一定的监控作用,但不能避免开关运行时出现的SF6密度示数"假高"现象,为消除密度示数"假高"、对环境温度的欠补偿和海拔影响,根本出路是开发新型智能化的SF6密度控制器。
