We construct a class of nuclear equations of state based on a schematic potential model, that originates from the work of Prakash et. al. [1], which reproduce the results of most microscopic calculations. The equations of state are used as input for solving the Tolman-Oppenheimer-Volkov equations for corresponding neutron stars. The potential part contribution of the symmetry energy to the tota...

PURPOSE Aortic Customize is a new concept for endovascular aortic aneurysm repair in which a non polymerized elastomer is injected to fill the aneurysm sac around a balloon catheter. The aim of this in vitro study was to investigate the extent of aneurysm wall stress reduction by the presence of a noncompliant elastomer cuff. METHODS A thin-walled latex aneurysm (inner radius sac 18 mm, inner...

Abstract In this work, we study the influence of f ( R , T ) gravity on rapidly rotating neutron stars. First discuss main aspects modified theory where gravitational Lagrangian is an arbitrary function Ricci scalar and trace energy–momentum tensor . Then present basic equations for stars including state used in work to describe hadronic matter. Some physical quantities interest are calculated ...

We study the magnon modes in the presence of a topological soliton in a two-dimensional Heisenberg easy-axis ferromagnet. The problem of magnon scattering on the soliton with arbitrary relation between the soliton radius R and the ‘‘magnetic length’’ D0 is investigated for partial modes with different values of the azimuthal quantum numbers m. Truly local modes are shown to be present for all v...

 In this research, the effect of the uniform electric field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot was studied using infinite potential model. In presence of strong electric field, due to the stark effect (perturbing electric field), the ground state energy would increase linearly. In presence of weak electric fields, the normalized bind...

conclusions the outside diameter/inside diameter ratio at the metaphyseal/diaphyseal junction of the distal radius on ap radiographs is suitable for use as a predictor of distal-radius bone density. further studies should be performed, and clinical utility evaluated. results the mean bmd was 0.559 (sd = 0.236) g / cm2. the mean outside diameter/inside diameter ratio was 1.24 (sd = 0.013); the r...

By applying the Edwards self-consistent field theory, we calculate the polymer density and free energy excesses caused by the presence of nanocolloids in the excluded volume polymer system. Using the obtained results, we have calculated the depletion potential U as a function of the separation between colloids, colloid radius, polymer volume fraction, and polymer gyration radius. Upon analyzing...
