Low Delay Noise Reduction and Dereverberation for Hearing Aids

EURASIP Journal on Advances in Signal Processing, 2009
A new system for single-channel speech enhancement is proposed which achieves a joint suppression of late reverberant speech and background noise with a low signal delay and low computational complexity.

The Hydrodynamic Noise Suppression of a Scaled Submarine Model by Leading-Edge Serrations

Journal of Marine Science and Engineering, 2019
High hydrodynamic noise is a threat to the survival of underwater vehicles. We investigated a noise suppression mechanism by putting leading-edge serrations on the sail hull of a scaled SUBOFF model, through numerical calculation and an experimental test.

HD‐tDCS Restores Perivascular AQP4 Polarization via PPARγ Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice

Advanced Science, EarlyView.
HD‐tDCS promotes recovery after intracerebral hemorrhage by enhancing PPARγ‐dependent astrocyte remodeling in a mouse model of ICH. This process suppresses proinflammatory astrocytic activation, restores perivascular AQP4 repolarization, and improves glymphatic influx and efflux, thereby facilitating hematoma and perihematomal edema clearance and ...

Targeted Degradation of Picornaviral 3C Protease via PROTACs Confers High Barrier to Viral Resistance and Broad‐Spectrum Antiviral Activity

Advanced Science, EarlyView.
This study reports D34 as the first PROTAC degrader that targets the 3C protease of picornaviruses. D34 effectively degrades EV71 3C protease via the ubiquitin‐proteasome pathway. More importantly, D34 exhibits a high resistance barrier and shows broad‐spectrum antiviral activity against multiple picornaviruses, highlighting its potential as a novel ...

Spatiotemporally Ultrasound‐Controlled Nanoparticles Reprogramming Immunostimulatory Antigen‐Presenting Cancer‐Associated Fibroblasts to Enhance Cancer Immunotherapy

Advanced Science, EarlyView.
We developed an ultrasound‐controlled biomimetic nanoplatform, mRNA/V@M NPs, to co‐deliver CD74 mRNA and V‐9302 for fibrotic TNBC therapy. CD74 mRNA reprograms myCAFs into antigen‐presenting apCAF cells through the CD74‐MHC II pathway, while V‐9302 induces ICD and activates MHC I‐CD8+ T cell immunity.
