A Self‐Evolving Agentic Framework for Metasurface Inverse Design
ABSTRACT Metasurface inverse design can realize complex optical functionality, but turning a target optical response into executable optimization code still requires substantial expertise in computational electromagnetics and solver‐specific software engineering. We present a sel...

Self-supervised graph attention networks for community-engaged lead contamination risk assessment
Lead contamination in residential water infrastructure poses a persistent public health risk, yet current assessment approaches rely on sparse homeowner sampling and tabular models that do not explicitly capture spatial dependencies in shared urban systems. Here we present a self...

Abstract In this work, high-quality Ge-doped (2̅01) β-Ga2O3 thin films were heteroepitaxially grown on c-plane sapphire substrates with offcut angles of 0°, 2°, 6°, and 8° using low-pressure chemical vapor deposition (LPCVD). Increasing the sapphire offcut promoted step-flow grow...

A Systematic Review of Cybercrime in Hybrid Cyber–Physical Space
Abstract Cybercrime increasingly extends beyond purely digital environments into hybrid cyber-physical spaces, creating new risks for urban infrastructure, mobility systems, and everyday socioeconomic activities. While criminology has long emphasized the importance of place in sh...

Abstract Background Dietary choices influence both risk and development of type 2 diabetes (T2D), but the precise mechanisms remain incompletely described. Dietary intake and lifestyle behaviors can alter epigenetic states with subsequent modulations on gene expression which then...

Abstract: A practitioner who runs a test of independence, a goodness-of-fit test, a likelihood-ratio test, or an analysis of variance reads a single p-value against a chi-square or F reference as calibrated. In large samples it is, because each is asymptotically chi-square. But w...
