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.

Reconnection of magnetic flux ropes driven by two-color Laguerre–Gaussian laser pulses in plasma

Matter and Radiation at Extremes
The generation and reconnection of magnetic flux ropes in a plasma irradiated by two Laguerre–Gaussian laser pulses with different frequencies and opposite topological charges are investigated numerically by particle-in-cell simulations. It is shown that

Psychological Safety, Medical Trauma and Adaptive Functioning in Long‐Term Conditions: A Multidisciplinary Integrative Approach

MultiPsych, Volume 1, Issue 3, September 2026.
ABSTRACT Living with a chronic health condition (CHC) can involve sustained exposure to uncertainty, bodily threat and disruption to identity, relationships and anticipated life trajectories. Although a substantial evidence base exists for psychological interventions in long‐term illness, theoretical accounts remain fragmented across modalities and ...

Magnetosonic Mach number dependence of the efficiency of reconnection between planetary and interplanetary magnetic fields [PDF]

, 2009
We present a statistical investigation into the magnetosonic Mach number dependence of the efficiency of reconnection at the Earth's dayside magnetopause.

Statistical Study of Betatron and Fermi Electron Acceleration at Dipolarization Fronts

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetic reconnection jets in Earth's magnetotail are regions of electron heating and acceleration. They are often associated with dipolarization fronts (DFs), which are characterized by sharp increases in the northward magnetic field component Bz ${B}_{z}$.

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]

, 2012
We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Discrete Energy Bands Beyond Galilean Moons: Bounce‐Phase Structuring of Jovian Magnetospheric Particles

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Discrete energy bands of ion fluxes, typically organized in velocity with equal separations, have been frequently observed in Jupiter's magnetosphere either in association with Galilean moons or in regions far from their influence. Here, we focus on the latter type and propose that these bands are manifestations of bounce‐phase structuring ...

Cross‐Vendor Validation of Proton Density Fat Fraction and T1 Mapping Using a Combined Proton Density Fat Fraction—T1 Phantom

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 482-492, August 2026.
ABSTRACT Background In chronic liver disease, fat and fibroinflammatory changes often coexist. However, their biomarkers, proton density fat fraction (PDFF) and T1, are typically assessed separately. Their reproducibility under mutual confounding remains unclear.

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.

Lymphatic Endothelial Cells in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Lymphatic endothelial cells (LECs) are dynamic regulators of tissue homeostasis and disease remodeling. In the healthy state, LECs coordinate interstitial fluid drainage, intestinal lipid transport, and immune trafficking and tolerance. Across disease settings, however, these same programs become maladaptively reprogrammed, contributing to barrier ...
