A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication

Advanced Science, EarlyView.
A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.

BRD4 Signaling Maintains the Differentiated State of β Cells

Advanced Science, EarlyView.
The comprehensive exploration revealed the critical role of BRD4 in β cells. BRD4 plays a fundamental role in maintaining β cell differentiation because both long‐term and acute BRD4 deficiency result in a reduction in insulin secretion and downregulation of differentiation markers.

SGCD: High‐Resolution Spatial Domain Characterization via Data Interpolation and Cell‐Type Deconvolution

Advanced Science, EarlyView.
SGCD presents a novel approach for tissue spatial domain identification by employing interpolation to estimate inter‐spot gene expression and deconvolution to resolve cell‐type composition in both sampled and interstitial regions. By integrating gene expression, cell type, and spatial coordinates within a graph contrastive learning framework, SGCD ...
