A Dynamical Cosmological Term from the Verlinde's Maps
In this letter it is proposed another generalization of the Verlinde's maps
for the case . Thermodynamical arguments combined with this
proposal conduce to a inverse square-law cosmological term behavior.Comment: 7 pages, minor changes added. v3: Minor changes in title, content and

Corrections to the Entropy in Higher Order Gravity
Thermal corrections to the entropy of black holes in the Lovelock gravity are
calculated. As the thermodynamic behavior of the black holes of this theory
falls into two classes, the thermodynamic quantities are computed in each case.
Finally, the logarithmic prefactors are obtained in two different limits.Comment: 11 pages. Comments and references added.v3.Minor changes in content

VCS Experiment - Radiative corrections
In this note we summarise the set of radiative corrections in photon-electroproduction process experiments. Then we describe and compare the different ways to determine and apply those corrections in a particular kinematical setting of our VCS experiment
Quasinormal Modes of Bardeen Black Hole: Scalar Perturbations
The purpose of this paper is to study quasinormal modes (QNM) of the Bardeen
black hole due to scalar perturbations. We have done a thorough analysis of the
QNM frequencies by varying the charge , mass and the spherical harmonic
index . The unstable null geodesics are used to compute the QNM's in the
eikonal limit. Furthermore, massive scalar field modes are also studied by
varying the mass of the field. Comparisons are done with the QNM frequencies of
the Reissner-Nordstrom black hole.Comment: 25 figures, Published in Physical Review D. Reference numbers
