General-Relativistic MHD for the Numerical Construction of Dynamical Spacetimes [PDF]

, 2002
We assemble the equations of general relativistic magnetohydrodynamics (MHD) in 3+1 form. These consist of the complete coupled set of Maxwell equations for the electromagnetic field, Einstein's equations for the gravitational field, and the equations of

Magnetothermodynamics: Measuring equations of state in a relaxed magnetohydrodynamic plasma [PDF]

, 2018
We report the first measurements of equations of state of a fully relaxed magnetohydrodynamic (MHD) laboratory plasma. Parcels of magnetized plasma, called Taylor states, are formed in a coaxial magnetized plasma gun, and are allowed to relax and drift ...

Generalized MHD equations

Journal of Differential Equations, 2003
The paper deals with the \(d\)-dimensional generalized MHD (GMHD) equations \[ \begin{aligned} &\partial_{t}u + u\cdot \nabla u =-\nabla P + b \cdot \nabla b - \nu (-\Delta)^{\alpha} u,\\ &\partial_{t}b + u \cdot \nabla b= b \cdot \nabla u - \eta (-\Delta)^{\beta} b, \end{aligned} \] where the fractional power \((-\Delta)^{\alpha}\) is defined via a ...

Comparison of spectral slopes of magnetohydrodynamic and hydrodynamic turbulence and measurements of alignment effects

, 2009
We performed a series of high-resolution (up to 1024^3) direct numerical simulations of hydro and MHD strong turbulence. We found that for simulations with normal viscosity the slopes for spectra of MHD are similar, although slightly more shallower than ...

Analytical Study of Certain Magnetohydrodynamic-alpha Models

, 2006
In this paper we present an analytical study of a subgrid scale turbulence model of the three-dimensional magnetohydrodynamic (MHD) equations, inspired by the Navier-Stokes-alpha (also known as the viscous Camassa-Holm equations or the Lagrangian ...

Kinetic formulation and global existence for the Hall-Magneto-hydrodynamics system [PDF]

, 2011
This paper deals with the derivation and analysis of the the Hall Magneto-Hydrodynamic equations. We first provide a derivation of this system from a two-fluids Euler-Maxwell system for electrons and ions, through a set of scaling limits. We also propose

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance

Advanced Science, EarlyView.
Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.
