There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this paper we show a relation between entanglement entropy and the brick wall model: the brick wall model seeks the maximal value of the entanglement entropy. In other words, the entanglement approach reduces to the brick w...

There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this paper, first, we show that the entanglement approach reduces to the brick wall model when we seek the maximal entanglement entropy. After that, the stability of the brick wall model is analyzed in a rotating background...

According to the masonry standard the compressive strength is basically dependent on factors such as the mortar strength and the relative values of unit and mortar strength. However interlocking brick has none or less use of mortar. Therefore there is a need to investigate the behavior of masonry walls using interlocking bricks. In this study a series of tests have been conducted; physical prop...

Quantum field theory in the near-horizon region of a black hole predicts the existence of an infinite number of degenerate modes. Such a degeneracy is regulated in the brick wall model by the introduction of a short distance cutoff. In this Letter we show that states of the brick wall model with non zero energy admit a further degeneracy for any given finite value of the cutoff. The black hole ...

Sao Paulo Med J/Rev Paul Med 2002; 120(2):35. The history of lung cancer spans many years, and over recent decades excision of tumors has been considered as the only effective treatment. In 1933 Graham performed the first successful pneumonectomy due to lung cancer. In 1937 Ochsner and DeBakey first concluded that smoking is a cause of lung cancer. This important observation was confirmed by Do...

This paper proposes, for low buildings, an integrated wall structure of a brick-stem-insulating layer, which plays a major part in both heat preservation and force bearing. The research team has tested the thermal performance of the structure, the results of which are satisfying. To further study the force-bearing performance, the paper carries out compressive tests of specimens of different st...

We consider the thermodynamics of minimally coupled massive scalar field in 3+1 dimensional Taub-NUT background. The brick wall model of 't Hooft is used. When Schwarzschild like coordinates are used it is found that the usual radial brick wall cutoff parameter is required to regularize the solution. Free energy of the scalar field is obtained through explicit counting of states. It is found th...

(2) a. These blockages can grow instance by instance, cycle by cycle, stone after stone, lifetime after lifetime, until the body starts to manifest these issues as disease b. Brick upon brick, stone upon stone they grow. c. She laid book upon book and built a staircase long enough to climb up and look over the wall. d. This mystery offers puzzle within puzzle. e. The Wall of Tears is a very big...
