Active Oscillations of Elastic Membranes Arising from the Coupling with a Catalytic Reaction

open access: yesAdvanced Science, EarlyView.
Coupling an elastic membrane to a catalytic reaction produces active oscillations that self‐sustain for hours: the membrane cyclically inflates and deflates as the reaction spontaneously activates and deactivates, without external power. Energy release is directly embodied in the oscillation dynamics, opening elasto‐chemical strategies for the physical

Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

open access: yesAdvanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Transparent and Flexible Broadband Microwave Absorber Based on a Nested Open‐Ring Metallic Mesh Architecture

open access: yesAdvanced Electronic Materials, EarlyView.
A flexible transparent microwave absorber is developed using a nested open‐ring metallic‐mesh structure, achieving over 90% absorption from 4.9 to 12.3 GHz with 75.8% visible transmittance. The device also maintains stable broadband absorption under bending, demonstrating its potential for flexible transparent electromagnetic protection.

Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability

open access: yesAdvanced Energy Materials, EarlyView.
Earth‐abundant single‐crystalline Mn‐rich DRX material faces a synthetic limit in particle‐size reduction. Our automated TEM workflow reveals interparticle compositional heterogeneity in early‐stage DRX, which forms minor orthorhombic impurities during cooling and necessitates prolonged annealing.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...
