A family of spherically symmetric solutions with horizon in the model with multi-component anisotropic fluid (MCAF) is obtained. The metric of any solution contains (n − 1) Ricci-flat “internal space” metrics and for certain equations of state (pi = ±ρ) coincides with the metric of intersecting black brane solution in the model with antisymmetric forms. Examples of simulation of intersecting M2...

A general thermodynamic argument shows that multi-component matter in full chemical equilibrium, with uniform entropy per baryon, is generally stably stratified. This is particularly relevant for neutron stars, in which the effects of entropy are negligible compared to those of the equilibrium composition gradient established by weak interactions. It can therefore be asserted that, regardless o...

– A phenomenological model for the unbinding transition of multi-component fluid membranes is proposed, where the unbinding transition is described using a theory analogous to Flory-Huggins theory for polymers. The coupling between the lateral phase separation of inclusion molecules and the membrane-substrate distance explains the phase coexistence between two unbound phases as observed in rece...

Determining accurate velocity measurements from observations of the Sun is vital importance to solar physicists who are studying wave dynamics in atmosphere. Weak chromospheric absorption lines, due dynamic events atmosphere, often consist multiple spectral components. Isolating these components allows for field and quiescent regimes be studied independently. However, isolating such particularl...

Abstract A simple multi-physical system for the potential flow of a fluid through shroud, in which mechanical component, like turbine vane, is placed, modeled mathematically. We then consider multi-criteria shape optimization problem, where component allowed to vary under certain set second-order Hölder continuous differentiable transformations baseline with boundary same continuity class. As o...
