Multiscale Fusion Network Based on Global Weighting for Hyperspectral Feature Selection
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Feature selection (FS) is an important way to achieve high-precision and efficient classification of hyperspectral remote sensing images. However, most existing FS methods use a fixed scale to extract features and the relationship between spatial and ...

Interference Pattern Caused by Bilateral Bone Conduction Stimulation Impairs Sound Localization
Advanced Science, EarlyView.This work explores how crosstalk‐induced wave interference affects bone conduction (BC) sound localization. Using a theoretical model, cadaveric vibrometry, and psychoacoustic tests, atypical BC lateralization patterns are revealed that contradict air conduction (AC) principles.
