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.

TRANSNATIONAL GENTRIFICATION IN NISEKO, JAPAN: A Model of Displacement Led by Linked Migration
International Journal of Urban and Regional Research, EarlyView.Abstract Transnational gentrification scholarship has provided insights into how transnational migration reshapes urban areas, yet its analytical lens has rarely extended to peripheral rural contexts outside Euro‐American settings, where distinct actors and mechanisms may emerge.
