The Effectiveness of Local‐Level Food Environment Policies in Improving Diet Quality of Socioeconomically Disadvantaged Population Groups. A Systematic Literature Review

open access: yesObesity Reviews, EarlyView.
ABSTRACT Socioeconomically disadvantaged populations consistently tend to have poorer diet quality, with food environments being a key factor underlying these disparities. Food environment‐oriented local government policies may constitute a positive solution for improvement.

High Dynamic Range Turbo‐FLASH B1 Mapping for Characterizing Multi‐Transmit Multi‐Receive RF Arrays, Validated at 7 T and 11.7 T

open access: yesMagnetic Resonance in Medicine, Volume 97, Issue 1, Page 240-249, January 2027.
ABSTRACT Purpose Transmit (B1+) and receive (B1−) sensitivities of parallel‐transmit/receive RF array are a prerequisite for modern ultra‐high‐field MRI. Their accurate mapping remains challenging for coils with high transmit dynamic range, particularly in regions with low combined‐mode B1+ magnitude, where standard reconstruction is impaired by noise.

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

open access: yesAdvanced Materials Technologies, Volume 11, Issue 21, 6 November 2026.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the
