RUNX1‐Mediated Hypoxic Signaling Impairs Myogenesis and Promotes Fibrosis in Myopathies

Advanced Science, EarlyView.
Myofiber overgrowth was associated with reduced blood flow and a potential hypoxic state in broiler breast muscle, accompanied by increased RUNX1 expression. Elevated RUNX1 impaired myogenic regeneration, promoted fibrosis, and disrupted the signaling niche required for efficient muscle repair, contributing to pathological degeneration in Wooden Breast

Hidden Giant Third‐Order Nonlinear Circular Dichroism in Chiral Two‐Dimensional Halide Perovskite

Advanced Science, EarlyView.
We demonstrate hidden giant third‐harmonic generation circular dichroism (THG‐CD) in chiral two‐dimensional halide perovskite. Although conventional polarization‐integrated THG measurement shows almost no chiral optical response, polarization‐resolved measurement reveals a hidden capability for nearly perfect discrimination of incident circularly ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
