The paper presents some specific applications of cubic equations of state (EOS) in Norak Hydro and points out some aspects of such equations that one should be aware of when using them or when developing new equations. Is is emphasized that the use of EOS to calculate vapor-liquid equilibrium is inherently empirical. Activity coefficients predicted’ for some systems by the Soave-Redlich-Kwong (...

We present calculations of quasiequilibrium sequences of irrotational binary neutron stars based on realistic equations of state (EOS) for the whole neutron star interior. Three realistic nuclear EOSs of various softness and based on different microscopic models have been joined with a recent realistic EOS of the crust, giving in this way three different EOSs of neutron-star interior. Computati...

We consider the influence of potential quark matter existing at high densities in neutron star interiors on gravitational waves (GW) emitted in a binary neutron star merger event. Two types of equations of state (EoS) at zero temperatures are used, one describing pure nuclear matter, the other nuclear matter with a phase transition to quark matter at very high densities. Binary equilibrium sequ...

BACKGROUND Severe and persistent mental illnesses in children and adolescents, such as early- onset schizophrenia spectrum (EOSS) disorders and pediatric bipolar disorder (pedBP), are increasingly recognized. Few treatments have demonstrated efficacy in rigorous clinical trials. Enduring response to current medications appears limited. Recently, olanzapine was approved for the treatment of adol...

Three parameterizations DOPS1, DOPS2, and DOPS3 (named after the Department of Physics Shimla) Relativistic Mean Field (RMF) model have been proposed with inclusion all possible self mixed interactions between scalar-isoscalar (\sigma), vector-isoscalar (\omega) vector-isovector (\rho) mesons up to quartic order. The generated parameter sets are in harmony finite bulk nuclear matter properties....

Two super cubic convergence methods to solve systems of nonlinear equations are presented. The first method is based on the Adomian decomposition method. We state and prove a theorem which shows the cubic convergence for this method. But numerical examples show super cubic convergence. The second method is based on a quadrature formulae to obtain the inverse of Jacobian matrix. Numerical exampl...

We study the effect of cosmological constant on radial oscillations and gravitational wave echoes (GWEs) non-rotating strange stars. To depict star configurations we used two forms equations state (EoSs), viz., MIT Bag model EoS linear EoS. By taking a range positive negative values constant, corresponding mass-radius relationships for these stars have been calculated. For this purpose, first s...

By applying finite difference formula to time discretization and the cubic B-splines for spatial variable, a numerical method for solving the inverse system of Burgers equations is presented. Also, the convergence analysis and stability for this problem are investigated and the order of convergence is obtained. By using two test problems, the accuracy of presented method is verified. Additional...
