Journal of the Royal Anthropological Institute, EarlyView.This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.

International Journal of Urban and Regional Research, EarlyView.Abstract What happens when venture capitalists try to reinvent housing in their own image? Synonymous with the rise of Big Tech, venture capitalists (VCs) are asset managers that invest in early‐stage companies, pursuing aggressive growth and market domination. Since the 2008 financial crisis, VCs have poured huge sums into real estate start‐ups.

Cancer Science, EarlyView.Accurate pT staging in muscle‐invasive bladder cancer is essential for treatment and prognosis, but current methods rely on time‐consuming and variable microscopic evaluation. We developed a graph neural network–based model that integrates multi‐scale whole‐slide images to automate pT staging, achieving excellent performance with an AUC of 0.911 and ...
