Programmable van der Waals Heterojunction for Multifunctional Integration

SmartMat, Volume 7, Issue 4, August 2026.
A MoS2/MAPbBr3 van der Waals heterostructure is programmed by gate bias to switch among photodetector, synaptic transistor, and gate‐bias‐assisted optical‐memory modes. Gate‐controlled carrier trapping tunes the response timescale, enabling mode reconfiguration in a single device.

Self‐management in gestational diabetes mellitus in Bangladesh: Determinants from women and caregivers' perspectives employed a cross‐sectional study

Journal of Diabetes Investigation, Volume 17, Issue 8, Page 1409-1418, August 2026.
This prevalence study evaluated 251 patient‐caregiver dyads across four tertiary hospitals in Dhaka, Bangladesh to identify the determinants of gestational diabetes mellitus (GDM) self‐management practice. Suboptimal self‐management was found highly prevalent at 68.5% of patients, driven by critical gaps in glycemic monitoring, dietary control, and ...

Corporate Quasi‐Sovereignty: Big Tech and the Politics of Sovereign Authority in the Digital Age

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT As private technology firms expand their control over critical infrastructures, questions of sovereignty and governance are increasingly displaced from states to corporate actors. Existing scholarship on sovereignty assumes that authority is either monopolized by states or shared through institutionalized public–private arrangements.
