We consider a five-dimensional constant curvature black hole, which is constructed by identifying some points along a Killing vector in a five-dimensional AdS space. The black hole has the topology M4 × S, its exterior is not static and its boundary metric is of the form of a three-dimensional de Sitter space times a circle, which means that the dual conformal field theory resides on a dynamica...

OBJECTIVE Our study examined the prognostic factors involved in the outcome of patients with chronic subdural hematoma (CSDH) who had undergone burr hole drainage procedures, and investigated the association between outcome and traumatic head injury. In addition, we explored factors related to recurrence. METHODS This study enrolled 238 patients with CSDH who had undergone burr hole drainage....

Hawking radiation is viewed as a tunnelling process. In this way the effect of selfgravitation gives rise to semiclassical corrections to the entropy of the (2 + 1) BTZ black hole. The modified entropy, due to specific modelling of the self-gravitation effect, of the (2 + 1) BTZ black hole is evaluated. To first order in ω which is a shell of energy radiated outwards the event horizon of the BT...

We propose that for non-localizable energy distribution the relevant energy condition is determined by the gravitational field energy which is negative for positive non-gravitational energy. That is negativity of the non-localized energy is the ”positive” energy condition. This would have direct application and relevance for a black hole on the brane which would be sitting in a trace free stres...

2014 The relaxation of the electron energy distribution function (edf) in N2 post discharge regime has been studied by solving the Boltzmann equation without the term due to the electric field. The results have been obtained both in the presence and in the absence of superelastic vibrational collisions. In the first case the electron energy distribution function relaxes toward nearly time indep...

The sonic analogue of a gravitational black hole in dilute-gas Bose-Einstein condensates is investigated. It is shown that there exist both dynamically stable and unstable configurations which, in the hydrodynamic limit, exhibit a behavior completely analogous to that of gravitational black holes. The dynamical instabilities involve creation of quasiparticle pairs in positive and negative energ...

ABSTRACT In this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. A chemical kinetic model was developed to understand the reaction better. The modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (P×τ). The β value is trait of the energy cost, whatever this value was leeser indicated ...

A NBI heated discharge is modeled with TRANSP under the HL-2A condition. LH wave is injected into the target plasma heated by NBI with a nearly symmetric power spectrum to control the current profile. Due to the off-axis driven current and electron heating, an optimized q-profile, of which the magnetic shear is weak in the central region and negative in the mid-plasma region (x~0.5-0.65), is fo...

Abstrati-The transport properties of holes in Si, _ ,Ge, are studied with a Monte Carlo technique. If the strain is applied to the Si, _ ,Ge, channel, it raises the degeneracy of the heavy-hole and light-hole bands: for compressive strain, the heavy-hole band lies at a higher energy than the light-hole band, while for tensile strain, the order reverses, although it is technologically uncertain ...

The interaction energy between two black holes at large separation distance is calculated. The first term in the expansion corresponds to the Newtonian interaction between the masses. The second term corresponds to the spin-spin interaction. The calculation is based on the interaction energy defined on the two black holes initial data. No test particle approximation is used. The relation betwee...
