Endothelial YAP Signaling Promotes Blood‐Spinal Cord Barrier Repair in Mice After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Endothelial YAP is required for blood‐spinal cord barrier repair after spinal cord injury. YAP‐dependent vascular repair is associated with ANGPT1/PI3K/AKT signaling in vivo and may involve endothelial‐pericyte paracrine interactions. By supporting vascular remodeling, tight junction restoration, restored pericyte coverage, and astrocyte‐vascular ...

Tunable p–p Interactions Along Linear Chains Control Metavalent Bonding in Chalcogenide Heterostructures

open access: yesAdvanced Science, EarlyView.
Substitution of Sr at the Pb site within an atomic plane of PbTe perturbs the p–p hopping network. Since Sr does not support the p–p interaction key to metavalent bonding along (‐Pb‐Te‐) chains, long‐range electronic charge transfer in response to displacement of Pb is stalked at the Sr site.

Single‐Sensor Vibration Sensing in Anisotropic Composites Enabled by Disordered Metasurfaces

open access: yesAdvanced Science, EarlyView.
This work develops a single‐sensor vibration sensing (SSVS) framework that integrates disordered metasurfaces with compressive sensing. Comprehensive numerical and experimental validations demonstrate that, by manipulating anisotropic guided wave propagation through metasurfaces, the proposed SSVS framework enables high‐fidelity multi‐source vibration ...
