The BTZ stationary black hole solution is considered and its mass and angular momentum are calculated by means of Nöther theorem. In particular, relative conserved quantities with respect to a suitably fixed background are discussed. Entropy is then computed in a geometric and macroscopic framework, so that it satisfies the first principle of thermodynamics. In order to compare this more genera...

The entropy of a BTZ black hole in the presence of gravitational Chern-Simons terms has previously been analyzed using Euclidean action formalism. In this paper we treat the BTZ solution as a two dimensional black hole by regarding the angular coordinate as a compact direction, and use Wald’s Noether charge method to calculate the entropy of this black hole in the presence of higher derivative ...

OBJECTIVES New data suggest that glioma stem-like cells (GSCs) and neural stem/progenitor cells (NSCs) may share common origins. GSCs drive tumor proliferation and appear to be resistant to classic chemotherapy, while the effects of chemotherapy on NSCs are not well studied. As the role of NSCs in learning and memory is increasingly recognized, we need to identify drugs that reduce neurotoxicit...

A bstract We go “back to basics”, studying accelerating systems in 2 + 1 AdS gravity ab initio . find three classes of geometry, which we interpret by holographically their physical parameters. From these, construct stationary, point particles; one-parameter extensions the BTZ family resembling an black hole; and new solutions including a novel “BTZ geometry” not continuously connected hole as ...

Although the introduction of bortezomib and immunomodulatory drugs has led to improved outcomes in patients with multiple myeloma, the disease remains incurable. In an effort to identify more potent and well-tolerated agents for myeloma, we have previously reported that 1'-acetoxychavicol acetate (ACA), a natural condiment from South-East Asia, induces apoptotic cell death of myeloma cells in v...

Whether or not system is unitary can be seen from the way it, if perturbed, relaxes back to equilibrium. The relaxation of semiclassical black hole can be described in terms of correlation function which exponentially decays with time. In the momentum space it is represented by infinite set of complex poles to be identified with the quasi-normal modes. This behavior is in sharp contrast to the ...

Submitted 5 Inactivating PSMB5 mutations and P-glyco-protein (MDR1/ ABCB1) mediate resistance to proteasome inhibitors: ex vivo efficacy of (immuno) proteasome inhibitors in mononuclear blood cells from rheumatoid arthritis patients 106 Abstract Bortezomib (BTZ), a registered proteasome inhibitor (PI) for multiple myeloma, has also been proposed as a potential anti-rheumatic agent. Its reported...

I review the classical and quantum properties of the (2+1)dimensional black hole of Bañados, Teitelboim, and Zanelli. This solution of the Einstein field equations in three spacetime dimensions shares many of the characteristics of the Kerr black hole: it has an event horizon, an inner horizon, and an ergosphere; it occurs as an endpoint of gravitational collapse; it exhibits mass inflation; an...

We derive an exact expression for the partition function of the Euclidean BTZ black hole. Using this, we show that for a black hole with large horizon area, the correction to the Bekenstein-Hawking entropy is −3/2 log(area), in agreement with that for the Schwarzschild black hole obtained in the four dimensional canonical gravity formalism and also in a Lorentzian computation of BTZ black hole ...
