Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning
Advanced Intelligent Discovery, EarlyView.This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Hybrid Granular–Elastomer Jamming With Confinement‐Mediated Stiffening
Advanced Intelligent Systems, EarlyView.A granular–elastomer hybrid jamming medium enables isotropic, repeatable stiffness modulation by exploiting vacuum‐induced confinement of an elastomeric network rather than particle friction. The actuator supports large 3D deformations (bending, folding, and twisting), retains programmed shapes when unjammed, and achieves an ~8× stiffness increase and ...

Border harm and affective injustice: The politics of anger at the Melilla border, Spain
American Journal of Community Psychology, EarlyView.Abstract This article examines protests in a detention center in Melilla, Spain—a site where structural violence intersects with the everyday harms of confinement. Adopting a justice and dignity‐centered perspective, we analyze grassroots forms of resistance emerging at the border. The study focuses on the protests of Tunisian migrants and explores the
