Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?

Observation of Interchange Reconnection on Mars

The Astrophysical Journal, 2023
Without a global dipole magnetic field, Mars has magnetic anomalies, i.e., crustal fields, in the southern hemisphere and interesting flexible magnetic fields in the magnetotail.

Kinematics of relativistic magnetic reconnection [PDF]

Physical Review Letters, 1994
We study the relativistic generalizations of two-dimensional Sweet-Parker and Petschek reconnection models in the context of a relativistic pair plasma. The solutions show that if the outflow velocity from the resistive region approaches the relativistic Alfven speed, the outflow density increase from Lorentz contraction allows a much faster inflow and

Auroral Emissions on Ganymede: New Constraints on Their Electron Energy Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Auroral emissions on Ganymede provide critical insights into its magnetospheric dynamics and atmospheric composition. Using a physics‐based atmospheric model with recent atmospheric observations and laboratory measurements of electron‐impact cross‐sections, this study revisits and significantly refines the relationship between auroral emission

Laboratory observation of plasmoid-dominated magnetic reconnection in hybrid collisional-collisionless regime

Communications Physics, 2022
Magnetic reconnection drives the ejection of plasmas during solar flares through changes in the magnetic fields. Here, the authors use a laboratory-based experiment to create magnetic reconnection in a regime in which the plasma on one side of the ...

Flow-turbulence interaction in magnetic reconnection

, 2011
Roles of turbulence in the context of magnetic reconnection are investigated with special emphasis on the mutual interaction between flow (large-scale inhomogeneous structure) and turbulence. In order to evaluate the effective transport due to turbulence,

Finding Local Parallel Electric Fields in Magnetotail Reconnection Using a Two‐Spacecraft Method

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the use of a novel two‐spacecraft Liouville‐mapping method using data from the Magnetospheric Multiscale mission to determine local magnetic‐field‐aligned (parallel) electric fields in the Earth's magnetotail. The method detects the presence of local acceleration potentials by mapping phase‐space density between electron ...
