Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High Voltage, EarlyView.ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

Climate Change and (Mal)Adaptation in Tourism‐Intensive Alpine Regions
The Political Quarterly, EarlyView.Abstract Tourism, especially in winter, accounts for a large share of economic income in Alpine regions. At the same time, these regions are more severely affected by climate change, leading to shorter winter seasons and reduced snow cover. This presents a pressing issue for areas reliant on income from winter tourism through activities such as skiing.

Journal of the Royal Anthropological Institute, EarlyView.The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950
Gender &History, EarlyView.ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.
