Multiscaling in Models of Magnetohydrodynamic Turbulence [PDF]
, 1997 From a direct numerical simulation of the MHD equations we show, for the first time, that velocity and magnetic-field structure functions exhibit multiscaling, extended self similarity (ESS), and generalized extended self similarity (GESS).

Fluids, 2020 In order to ensure stable power exhaust and to protect the walls of fusion reactors, liquid metals that are fed to the wall surface through a capillary porous system (CPS) are considered as alternative plasma-facing components (PFCs).

Global well-posedness of the MHD equations in a homogeneous magnetic field [PDF]
, 2016 In this paper, we study the MHD equations with small viscosity and resistivity coefficients, which may be different. This is a typical setting in high temperature plasmas.

A three-dimensional reduced MHD model consistent with full MHD [PDF]
Physics of Plasmas, 2019 Within the context of a viscoresistive magnetohydrodynamic (MHD) model with anisotropic heat transport and cross field mass diffusion, we introduce novel three-term representations for the magnetic field (background vacuum field, field line bending, and field compression) and velocity (E→×B→ flow, field-aligned flow, and fluid compression), which are ...

Remarks on Liouville type theorems for the steady MHD and Hall-MHD equations [PDF]
, 2021 In this note we investigate Liouville type theorems for the steady three dimensional MHD and Hall-MHD equations, and show that the velocity field $u$ and the magnetic field $B$ are vanishing provided that $B\in L^{6,\infty}(\mathbb{R}^3)$ and $u\in BMO^{-1}(\mathbb{R}^3)$, which state that the velocity field plays an important role.

On the magnetohydrodynamic load and the magnetohydrodynamic metage [PDF]
Physics of Plasmas, 2008 In analogy with the load and the metage in hydrodynamics, this paper defines magnetohydrodynamic load and magnetohydrodynamic metage in the case of magnetofluids. They can be used to write the magnetic field in MHD in Clebsch’s form. It has been shown herein how these two concepts can be utilized to derive the magnetic analog of the Ertel’s theorem and

Nonlinear theory of non-axisymmetric resonant slow waves in straight magnetic flux tubes [PDF]
, 2000 Nonlinear resonant slow magnetohydrodynamic (MHD) waves are studied in weakly dissipative isotropic plasmas for a cylindrical equilibrium model. The equilibrium magnetic field lines are unidirectional and parallel with the z axis. The nonlinear governing

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Background Refractory chronic migraine (rCM) is a highly disabling condition for which novel safe and effective treatments are needed. Safety and long‐term efficacy of paresthesia‐free high cervical 10 kHz spinal cord stimulation (SCS) were here prospectively evaluated for the treatment of rCM.
