A novel approach is described towards a microscopic understanding of the BekensteinHawking entropy of the simplest black hole – the Schwarzschild black hole. It is based at an intermediate step on the description of the black hole in terms of dual Euclidean brane/anti-brane pairs of type-IIB string-theory. By counting specific chain structures on the brane-complex one can reproduce the correct ...

In this paper the dynamic of a droplet on a surface with a hole is investigated under gravitational effect by using lattice Boltzmann method. Incompressible two-phase flow with high density ratio proposed by Lee is considered. Cahn’s theory is used to observe the wettability of the surface in contact with liquid and gas phases. Several parameters such as contact angle, surface tension and gravi...
