Responsive Phase Gradient Metasurface for Laser Stealth and Dynamic Thermal Camouflage

open access: yesLaser &Photonics Reviews, EarlyView.
The graphical abstract depicts a phase‐gradient metasurface enabling directional scattering and emissivity‐controlled thermal radiation. The engineered phase profile redistributes the reflected optical momentum, suppressing specular reflection and generating non‐specular scattering.

Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

open access: yesLaser &Photonics Reviews, EarlyView.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Osteoarthritis: An Immuno‐Inflammatory Disease‐Mechanisms of Immune Cell Dysregulation and Potential Therapeutic Strategies

open access: yesMed Research, EarlyView.
This review summarizes the immuno‐inflammatory mechanisms driving the pathogenesis of osteoarthritis (OA), extending beyond the traditional view of OA as a purely degenerative disease to incorporate immune cell infiltration, inflammatory factor release, and the formation of a chronic low‐grade inflammatory microenvironment.

A Geometric Interpretation for the Algebraic Properties of Second‐Order Ordinary Differential Equations

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.
ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

The Mexico City Policy in US Development Policy and Its Backlash‐Frontlash‐Logic

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The Mexico City Policy provides for the discontinuation of U.S. government funding for foreign non‐governmental organizations (NGOs) that provide legal abortion services. While Republican administrations have repeatedly pushed for the introduction of the Mexico City Policy after their re‐election, those regulations have been rescinded by ...
