Scaling laws of the plasma velocity in visco-resistive magnetohydrodynamic systems
Autor: A. Krupka, M.-C. Firpo
Publikováno v: Fundamental Plasma Physics, Vol 10, Iss , Pp 100044- (2024)
We consider a visco-resistive magnetohydrodynamic modelling of a steady-state incompressible tokamak plasma with a prescribed toroidal current drive, featuring constant resistivity η and viscosity ν. It is shown that the plasma velocity root-mean-s

Coexisting crystal and liquid-like properties in a 2D long-range self-consistent model
Autor: J. M. Maciel, M. A. Amato, M. -C. Firpo
Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-10 (2018)
Abstract A two-dimensional class of mean-field models serving as a minimal frame to study long-range interaction in two space dimensions is considered. In the case of an anisotropic mixed attractive-repulsive interaction, an initially spatially homog

Breaking up-down symmetry with magnetic perturbations in tokamak plasmas: increase of axisymmetric steady-state velocities
Autor: M.-C. Firpo, H. Oueslati

Physics of Plasmas, American Institute of Physics, 2020, 27 (10), pp.102501. ⟨10.1063/5.0016566⟩
International audience; Plasma rotation plays a crucial role on heat and particle confinement in tokamaks. To consider this issue, we numerically compute the axisymmetric steady states of the visco-resistive magnetohydrodynamic equations including th

EARLY OUT-OF-EQUILIBRIUM BEAM-PLASMA EVOLUTION: POSSIBLE FORMATION OF A BEAM RING STRUCTURE
Autor: M. C. Firpo, Agustin Lifschitz
Publikováno v: International Journal of Modern Physics B. 21:633-636
We solve analytically the out-of-equilibrium initial stage that follows the injection of a radially finite electron beam into a plasma at rest and test it against particle-in-cell simulations. For initial large beam edge gradients and not too large b

Many physical systems may be considered as isolated assemblies of N bodies interacting via long-range pair interactions. This is the case for systems ranging from charged particles interacting via Coulomb interaction to self-gravitating massive objec

Bone marrow transplantation with interleukin-1 plus kit-ligand ex vivo expanded bone marrow accelerates hematopoietic reconstitution in mice without the loss of stem cell lineage and proliferative potential
Autor: M O, Muench, M T, Firpo, M A, Moore

Cytokine combinations were tested for their ability to expand murine bone marrow (BM) progenitors in short-term suspension cultures (delta- cultures) with the aim of providing an enriched source of progenitors for BM transplantation (BMT). In a compa
