Reconstruction of Two‐Dimensional Magnetohydrodynamic and Hall Magnetohydrodynamic Equilibria in Space Using Physics‐Informed Neural Networks

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract We present a novel data analysis technique based on physics‐informed neural networks (PINNs) to reconstruct two‐dimensional (2D) magnetohydrodynamic (MHD) and Hall MHD equilibria in a space plasma from in situ spacecraft measurements. Our method incorporates the steady‐state MHD or Hall MHD equations—a set of partial differential equations ...

Why Coronal Mass Ejections Arrive Differently: Solar Cycle Modulation Through Solar Wind Structure

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract Coronal Mass Ejections (CMEs) are large structures of magnetized plasma ejected from the Sun's atmosphere into the heliosphere. The interaction of CMEs with the ambient solar wind during propagation affects arrival time and speed at Earth. Since the solar wind structure changes with the solar cycle, variability in the transit times and arrival

MIDAS and HIT‐6 Questionnaires Versus Headache Diaries for Monitoring Treatment Response to Erenumab in Migraine: A REFORM Study

open access: yesEuropean Journal of Neurology, Volume 33, Issue 4, April 2026.
Treatment response to anti‐CGRP medications for migraine is typically defined as a ≥ 50% reduction in monthly migraine days. However, the use of patient‐reported outcome measures (such as MIDAS and HIT‐6) has been proposed as alternative options.

Effectiveness and tolerability of galcanezumab for migraine prevention in patients ≥65 years: A real‐life multicenter study

open access: yesHeadache: The Journal of Head and Face Pain, Volume 66, Issue 4, Page 939-949, April 2026.
Plain Language Summary This study shows that galcanezumab is equally effective and well‐tolerated in patients aged 65 and older as in younger patients, with a higher proportion of excellent responders in older patients. Despite having more baseline headache days, older patients responded well to the treatment, with age being linked to better outcomes ...
