Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 4, Page 1524-1533, April 2026.Abstract Purpose This study aims to test whether week‐long wrist accelerometry combined with deep learning can (i) distinguish healthy individuals from people with knee osteoarthritis (KOA), (ii) separate prodromal KOA from established KOA, and (iii) identify individuals who will receive a KOA diagnosis within 5 years.

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...

European Journal of Neuroscience, Volume 63, Issue 7, April 2026.Wearable systems using inertial sensors can misclassify voluntary standing as freezing of gait (right). Adding eye‐gaze kinematics to a deep learning model reduces this error (left): standing misclassified as freezing decreases from 59.1% to 13.6%, standing recall more than doubles from 36.4% to 81.8%, and macro‐averaged F1 improves significantly from ...

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...

Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems
Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2456-2462, 15 March 2026.ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.
