Black hole uniqueness is known to fail in higher dimensions, and the multiplicity of black hole phases leads to phase transitions physics in General Relativity. The black-hole black-string transition is a prime realization of such a system and its phase diagram has been the subject of considerable study in the last few years. The most surprising results seem to be the appearance of critical dim...

Local scour around a cylindrical pier in a channel with an erodible bed or natural bed is a common problems in bridge or pile supported structure. The highly unsteady complex flow field around a circular pier produces scour hole mainly for the presence of vortices. The main mechanism that drives the formation and evolution of the scour hole around bridge pier is horse shoe vortex motion. In the...

Background & Importance: Chronic subdural hematoma (CSH) is one of the most frequent intracranial hemorrhages in adults. However, gold standard treatment of CSH is not yet defined. Since the 80’s, closed drainage is a standard among techniques using drains because the open type has been incriminated in high rates of postoperative infections. However, closed drainage requires mat...

A brief review of recent research on soliton and black hole solutions of Einstein’s equations with nonlinear field sources is presented and some open questions are pointed out.

ABSTRACT A promising channel for producing binary black hole mergers is the Lidov–Kozai orbital resonance in hierarchical triple systems. While this mechanism has been studied isolation, distribution of such time and across star-forming environments not well characterized. In work, we explore Lidov–Kozai-induced open clusters, combining semi-analytical Monte Carlo methods to calculate merger ra...

One of the methods used to investigate the damaged zone in rock structure is the acoustic emission method. This method is based on receiving the elastic waves that are produced by deformation and cracking of the rock mass around the underground excavation. In this research, a study is conducted on the rock samples by a numerical method to investigate the damaged zone caused by the excavat...
