World Medical &Health Policy, Volume 18, Issue 3, September 2026.ABSTRACT This study examines the association between catastrophic health expenditure (CHE) and distress financing among India's uninsured “missing middle,” a population largely excluded from public insurance schemes and private coverage. While healthcare‐induced financial hardship is well documented, evidence on subsequent coping strategies among this ...

Inferring alternative ecosystem states with field survey data
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Light‐activated gas sensors hold significant potential in environmental monitoring and smart Internet of Things (IoT) owing to their advantage in room temperature operation. Nevertheless, due to a narrow light absorption range, high photocarrier recombination rate, and weak redox activity of the sensing material, the performance enhancement of

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Through grain boundary segregation engineering, a crack‐free high‐strength CoCrNi medium‐entropy alloy (MEA) can be successfully fabricated via laser powder bed fusion (PBF‐LB). The influence of micron‐sized TiC particles on microstructural evolution, grain boundary segregation behavior, and mechanical properties was systematically ...
