Van der Waals Template‐Assisted Growth of Two‐dimensional Sb2S3

Advanced Science, EarlyView.
Van der Waals (vdW) template‐assisted growth of atomically thin two‐dimensional (2D) Sb2S3 on monolayer MoS2 single crystals is demonstrated, overcoming its thermodynamically preferred one‐dimensional (1D) growth. The resulting sub‐8 nm nanosheets show uniform coverage, atomically sharp interfaces, and enhanced broadband optoelectronic performance as ...

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, EarlyView.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

Advanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Detecting Awareness in the Intensive Care Unit Using Functional Near‐Infrared Spectroscopy

Annals of Neurology, EarlyView.
Objective Signs of awareness after acute severe brain injury are critical for informing goals‐of‐care decisions, ranging from the continuation of aggressive life‐sustaining therapy to comfort‐focused end‐of‐life measures. However, awareness may go undetected in some critically ill patients when assessed using bedside behavioral neurological examination.

Optimized laser turrets for minimum phase distortion [PDF]

, 1980
An analysis and computer program which optimizes laser turret geometry to obtain minimum phase distortion is described. Phase distortion due to compressible, inviscid flow over small perturbation laser turrets in subsonic or supersonic flow is calculated.
