With the semiclassical Landau-Vlasov transport model we studied the stopping observable RE, the energy-based isotropy ratio, for the Xe129+Sn120 reaction at beam energies spanning 12A to 100A MeV. We investigated the impacts of the nonlocality of the nuclear mean field, of the in-medium modifi...
Gas-gun experiments are simulated and compared with experimental data for a material with 2Al, Fe(2)O(3), 20 wt % Epon 828, and voids, in which the reaction initiation threshold was not reached. The simulation integrates conservation equations and momentum balance using a second-order finite...
The equation of states obtained from these effective interactions are used to study liquid–gas phase transition in nuclear matter.关键词: Momentum and density dependence Mean field Equation of state Functional form Nuclear matter Finite-range effective interactions ...
In 1905 the Dutch physicist Hendrik Antoon Lorentz applied the kinetic equation for atoms (the formulation by the Austrian physicist Ludwig Eduard Boltzmann) to the behaviour of electrons in metals. Various physicists and mathematicians in the 1930s and ’40s further developed the plasma kinetic ...
Control equation Since the width-direction ratio of the suspension nozzle size to the slit is greater than 100, the edge effect can be disregarded, and the suspension nozzle's flow and heat transfer mode can be reduced to a two-dimensional flow that is represented using a two-dimensional Cart...
The equation of state (EOS) of hot, dense matter, is an important factor that characterizes the gravitational collapse of a star leading to a supernova explosion. This paper is aimed at providing a brief review of the EOS of hot, dense matter with particular reference to the treatment of ...
(or the entirety of) the governing equations using indirect observations. InMethods, we show that our approach outperforms state-of-the-art algorithms for governing-equation discovery, particularly in the low-data and high-noise regimes, and can be used in situations in which the entire state ...
I am trying to implement this equation ##−k∇^2 u = e^{-(x^2+y^2)}## using NDSolve in Mathematica. The idea is to solve for the temperature of a plate 10 x 10 units, with heat inputs as per the RHS. Here is my attempt: NDSolve[{ - Laplacian[u, {x, y}] == Exp...
In this paper, we apply Bayesian inference to constrain the nuclear equation of state parameters by using properties of neutron stars, including the maximum neutron star mass, radius, tidal deformability at 1.4 times the solar mass, and speed of sound. When the polytrope EOS parameter γ is fi...
