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, EarlyView.
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.

Interplay between magnetic reconnection and turbulence

, 2023
Shay, Michael A.Reconnection and turbulence frequently occur in plasmas, including laboratory, astrophysical and space plasmas. Over the past few decades, the interrelationship between turbulence and magnetic reconnection has been the focus of increasing

Dual‐Responsive Hydrogels Engineer Anisotropic Cellular Microenvironment to Modulate Stem Cell Organization and Fate

Small, EarlyView.
Collagen peptides hydrogels with tunable mechanical dynamics were developed by employing physical or chemical nanoparticle crosslinkers. Dual‐responsive hydrogels with magnetic‐driven alignment were fabricated under a low magnetic field and rapid UV exposure. The presence of biophysical anisotropy, enhanced biomechanical dynamics, and growth factors—as

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

Flare energy release by flux pile-up magnetic reconnection in a turbulent current sheet

, 2000
The power output of flux pile-up magnetic reconnection is known to be determined by the total hydromagnetic pressure outside the current sheet. The maximum energy-release rate is reached for optimized solutions that balance the maximum dynamic and ...

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 ...

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to
