Aberration correction in fetal ultrasound: Clinical evaluation on image quality improvement

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Obstetric ultrasound is key for assessing fetal growth and detecting anomalies, with image quality critical for diagnostic accuracy. Maternal body mass index (BMI) and other factors can impair quality. Aberration correction (AC) aims to reduce image quality degradation.

Harnessing cracks in metal films: Design strategies for stretchable conductors

open access: yesInfoMat, EarlyView.
In stretchable electronics, metal film‐based components function either as strain‐insensitive interconnects/electrodes or as strain‐sensitive sensors, both of which are governed by crack‐induced electromechanical responses, yet these two roles have often been discussed separately in previous reviews.
