Spatiotemporal Computational Meta‐Imager for Broadband Dual‐Layer Optical Convolution

Advanced Science, EarlyView.
A single‐layer polarization‐multiplexed meta‐imager achieves factorized dual‐layer broadband convolution via spatiotemporal kernel decomposition. Fixed Bessel‐vortex bases and time‐sequential liquid‐crystal modulation deliver tunable signed weights and in‐situ fabrication‐error compensation. Experiments verify improved classification performance across

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

The Potential of Zero Charge: An Interfacial Descriptor Governing Hydrogen Evolution Reaction on Bulk Metal Electrodes

Advanced Science, EarlyView.
This work establishes a dual‐descriptor framework incorporating hydrogen adsorption free energy and potential of zero charge, constructing a corrected 3D HER volcano plot. It reveals that surface charge and interfacial proton concentration jointly govern activity, beyond conventional 2D thermodynamic scaling relations. ABSTRACT While the Sabatier‐based
