Journal of Ultrasound in Medicine, EarlyView.Chorionic villus sampling (CVS) is a crucial prenatal diagnostic tool, but a declining number of procedures makes training a challenge. Here we describe a transcervical CVS simulator made from ballistic gelatin. Ninety‐three Maternal‐Fetal Medicine providers used the simulators during hands‐on workshops and completed surveys regarding their fidelity ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
Laser &Photonics Reviews, EarlyView.This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Modeling of Advanced Combat Helmet Under Ballistic Impact
Journal of Applied Mechanics, 2015 The use of combat helmets has greatly reduced penetrating injuries and saved lives of many soldiers. However, behind helmet blunt trauma (BHBT) has emerged as a serious injury type experienced by soldiers in battlefields. BHBT results from nonpenetrating ballistic impacts and is often associated with helmet back face deformation (BFD).
