Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Wall conditions in WEST during operations with a new ITER grade, actively cooled divertor

Nuclear Materials and Energy
Future fusion reactors like ITER and DEMO will have all-tungsten (W) walls and long pulses. These features will make wall conditioning more difficult than in most of the existing devices.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, Volume 4, Issue 2, May 2026.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Ionospheric Effects on Maximum Usable Frequency for a Cross‐Auroral and a Polar Cap HF Radio Link

Radio Science, Volume 61, Issue 5, May 2026.
Abstract Maximum usable frequency (MUF) is an important indicator of the ability of the ionosphere to support over‐the‐horizon propagation of high frequency (HF) radio waves. MUF depends on the location of the transmitter and receiver, and the structure of ionospheric electron density.

Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Statistical Auroral Absorption Model Parameterized by AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Energetic electron precipitation, often in association with enhanced geomagnetic activity, leads to increased D‐region ionization in the auroral region causing auroral absorption. A statistical auroral absorption model is presented for high‐latitudes (poleward of 50° magnetic latitude) based on data collected from 2010 to 2019 from 13 wide ...

DRFL: A Dual‐Encryption and Reputation Evaluation Defence Against Malicious Attacks on Federated Learning

IET Communications, Volume 20, Issue 1, January/December 2026.
Federated learning (FL) enables collaborative model training without collecting user data but faces security risks such as privacy breaches, poisoning, and free‐rider attacks. To address these challenges, we propose DRFL, a defense mechanism integrating dual encryption, reputation evaluation and blockchain to enhance security and transparency ...
