Pebble flow in the HTR-PM reactor core by GPU-DEM simulation: Effect of friction

Nuclear Engineering and Technology
The high-temperature gas-cooled reactor (HTGR) with spherical fuel elements contains complex pebble flow. The flow behavior of pebbles is influenced by various factors, such as pebble density, friction coefficient, wall structure, and discharge port size.

Sex differences in neuromodulatory subcortical systems and their implications for Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...

Collection, Collation, and Comparison of Near‐Earth In Situ CME Boundaries

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Coronal mass ejections (CMEs) drive space weather throughout the heliosphere so knowledge of their internal properties is key to understanding and eventually forecasting their effects. Typically observations are limited to single‐spacecraft encounters sampling one path that may or may not be representative of the overall structure.

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...
