New quantum effects in relativistic magnetohydrodynamics

, 2017
Chiral anomaly induces a new kind of macroscopic quantum behavior in relativistic magnetohydrodynamics, including the chiral magnetic effect. In this talk we present two new quantum effects present in fluids that contain charged chiral fermions: 1) the ...

Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

Heat Transfer, EarlyView.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

Quantitative Confounder Analysis of Electrocardiogram Signals in Cardiac Magnetic Resonance at 1.5, 3 and 7 T—Assessing Standardized Electrode Positions and Sequence Types—Towards Quality Assurance

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

MRI and Implant Safety at Low‐Field and Ultralow‐Field Strengths

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Despite its unequivocal value in radiological diagnosis, access to conventional high‐field MRI systems remains extremely uneven across the world. Access is particularly limited in underfunded and remote settings, due to the high cost and infrastructure requirements of MRI systems.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies

Rare Metals, EarlyView.
ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

Small, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

Extended Kelvin theorem in relativistic magnetohydrodynamics [PDF]

, 2000
We prove the existence of a generalization of Kelvin's circulation theorem in general relativity which is applicable to perfect isentropic magnetohydrodynamic flow. The argument is based on a new version of the Lagrangian for perfect magnetohydrodynamics.
