Topology of turbulence within collisionless plasma reconnection

Scientific Reports, 2023
In near-collisionless plasmas, which are ubiquitous in astrophysics, entropy production relies on fully-nonlinear processes such as turbulence and reconnection, which lead to particle acceleration.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Radiative Signatures of Magnetic Reconnection: An Approach to Remote Probing of Reconnection Dynamics

The Astrophysical Journal
Magnetic reconnection drives a wide range of astrophysical phenomena, including geomagnetic storms, solar flares, and activity in blazars. However, direct measurement of key reconnection observables remains challenging due to the remote and extreme ...

Visualizing and Quantifying microRNA‐Induced DNA Origami Separation at the Nanoscale

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
Clinically relevant miRNA biomarkers trigger the disassembly of DNA origami dimers into monomers through a toehold‐mediated strand displacement reaction. High‐speed AFM was used to visualize this reaction in real time, while solid‐state nanopore measurements quantified the populations of dimers and monomers, as well as the resulting miRNA concentration,

Intra‐Procedural Three‐Dimensional Rotational Angiography in Cryoballoon Ablation of Atrial Fibrillation: An RCT

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The impact of various imaging techniques on the safety and outcomes of atrial fibrillation (AF) ablation remains unclear. Intra‐procedural three‐dimensional rotational angiography (3DRA) is the least used imaging method despite some benefits.

Magnetohydrodynamics simulation of magnetic reconnection process based on the laser-driven Helmholtz capacitor-coil targets

Frontiers in Physics
Magnetic reconnection is an important rapid energy release mechanism in astrophysics. Magnetic energy can be effectively converted into plasma kinetic energy, thermal energy, and radiation energy.

Recent Progress in Understanding Solar Magnetic Reconnection [PDF]

Journal of Astronomy and Space Sciences, 2015
Magnetic reconnection is a fundamental process occurring in a wide range of astrophysical, heliospheric and laboratory plasmas. This process alters magnetic topology and triggers rapid conversion of magnetic energy into thermal heating and nonthermal ...

Explosive Turbulent Magnetic Reconnection [PDF]

Physical Review Letters, 2013
We report simulation results for turbulent magnetic reconnection obtained using a newly developed Reynolds-averaged magnetohydrodynamics model. We find that the initial Harris current sheet develops in three ways, depending on the strength of turbulence: laminar reconnection, turbulent reconnection, and turbulent diffusion.

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.
