Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

open access: yesAdvanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom

open access: yesIEEE Access, 2019
In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...

Lactylation‐Mediated HER2 Stabilization Promotes Trastuzumab Resistance in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Warburg effect‐derived lactate drives HER2 lactylation and trastuzumab resistance. Mechanistically, AARS1‐mediated lactylation stabilizes HER2 by inhibiting USP11‐dependent degradation and concurrently promotes HER2‐EGFR interaction. Importantly, inhibiting HER2 lactylation resensitizes gastric cancer cells to trastuzumab.
