Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
Advanced Physics Research, EarlyView.This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Seeing the Speaker's Face Enhances Second Language Shadowing: Neural and Behavioral Evidence
Language Learning, EarlyView.Abstract This functional magnetic resonance imaging (fMRI) study investigated how facial cues influence second language (L2) shadowing among 42 Japanese learners of English. Participants completed four conditions that varied by task type (listening vs. shadowing) and visual input (face vs. mosaic).

Correction of the effects of acoustic heterogeneity on thermoacoustic tomography using transmission ultrasound tomography [PDF]
, 2006 The effects of acoustic heterogeneities on thermoacoustic tomography (TAT) are examined and corrected. One assumption made in the existing reconstruction algorithms for thermoacoustic tomography is that biological tissue is acoustically homogeneous.

Optoacoustic Neuromodulator by In Situ Photothermal Curing of Polydimethylsiloxane
Advanced Optical Materials, Volume 14, Issue 16, 24 April 2026.Photoacoustics provides a powerful tool for generating miniaturized and patterned ultrasound field. Here, we report a novel, highly versatile method for fabricating optoacoustic emitters via an in situ photothermal curing process of PDMS. This technique enables high‐precision deposition across diverse platforms, including programmed flat substrates and
