Stepwise Regulation of Cellular Oxidative Stress via Conductive‐Piezoelectric Integrated Microstructured Conduits for Enhanced Nerve Regeneration

Advanced Science, EarlyView.
This study presents a conductive‐piezoelectric integrated microstructured conduit for peripheral nerve regeneration. The conduit combines reduced graphene oxide with a piezoelectric nanofiber membrane, enhancing nerve repair through physical guidance, oxidative stress inhibition, and ultrasound‐activated electrical stimulation.

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,
