human neurite exchange imaging (NEXI) at 500 mT/m diffusion gradients.

Unlabelled: Evaluating tissue microstructure and membrane integrity in the living human brain through diffusion-water exchange imaging is challenging due to requirements for a high signal-to-noise ratio and short diffusion times dictated by relatively fast exchange processes. The goal of this work was to demonstrate the feasibility of imaging of tissue micro-geometries and water exchange within the brain gray matter using the state-of-the-art Connectome 2.0 scanner equipped with an ultra-high-performance gradient system (maximum gradient strength=500 mT/m, maximum slew rate=600 T/m/s).

3D-printed aberration-free terahertz metalens for ultra-broadband achromatic super-resolution wide-angle imaging with high numerical aperture.

Terahertz (THz) lens constitutes a vital component in the THz system. Metasurfaces-based THz metalenses and classical bulky lenses are severely constrained by chromatic/ spherical aberration and the diffraction limit. Consequently, achromatic super-resolution THz lenses are urgently needed.

The need for pediatric sleep education to enhance healthcare for children and adolescents: A global perspective from a survey of members of the international pediatric sleep association.

Introduction: Sleep concerns have become increasingly common over the past few decades. This study outlines the perceived needs and gaps in pediatric sleep education, drawing insights from a diverse international cohort of pediatric sleep health professionals.

Methods: International Pediatric Sleep Association (IPSA) members were invited to complete an online survey examining a variety of topics related to pediatric sleep education developed by the education committee.

Stratifying vascular disease patients into homogeneous subgroups using machine learning and FLAIR MRI biomarkers.

This study proposes a framework to stratify vascular disease patients based on brain health and cerebrovascular disease (CVD) risk using regional FLAIR biomarkers. Intensity and texture biomarkers were extracted from FLAIR volumes of 379 atherosclerosis patients. K-Means clustering identified five homogeneous subgroups.
