Renormalization group flow of the Holst action
Abstract The renormalization group (RG) properties of quantum gravity are explored, using the vielbein and the spin connection as the fundamental field variables. The scale dependent effective action is required to be invariant both under spacetime...

First-order framework and domain-wall/brane-cosmology correspondence
Abstract We address the possibility of finding domain wall solutions from cosmological solutions in brane cosmology. We find first-order equations for corresponding cosmology/domain wall solutions induced on 3-branes. The quadratic term of energy...

New architecture for high efficiency DC-DC converter dedicated to photovoltaic conversion
Abstract The latest researches on photovoltaic energy conversion clearly show that the next generation systems will be both smarter and efficient, with insurance of greater security and modularity. They are clearly oriented nowadays on the...

Scale symmetry breaking from total derivative densities and the cosmological constant problem
Abstract The use in the action integral of totally divergent densities in generally coordinate invariant theories can lead to interesting mechanisms of spontaneous symmetry breaking of scale invariance. With dependence in the action on a metric...

Improved peak shape fitting in alpha spectra
Abstract Peak overlap is a recurrent issue in alpha-particle spectrometry, not only in routine analyses but also in the high-resolution spectra from which reference values for alpha emission probabilities are derived. In this work, improved peak...

Inhomogeneous dusty universes and their deceleration
Abstract Exact results stemming directly from Einstein equations imply that inhomogeneous universes endowed with vanishing pressure density can only decelerate, unless the energy density of the universe becomes negative. Recent proposals seem to...

Unified parametrization for quark and lepton mixing angles
Abstract We propose a new parametrization for the quark and lepton mixing matrices: the two 12-mixing angles (the Cabibbo angle and the angle responsible for solar neutrino oscillations) are at zeroth order π ...

BMN operators and string field theory
Abstract We extract from gauge theoretical calculations the matrix elements of the SYM dilatation operator. By the BMN correspondence this should coincide with the 3-string vertex of light cone string field theory in the pp-wave background. We find...

Fluctuations of strangeness and deconfinement phase transition in nucleus–nucleus collisions
Abstract We suggest that the fluctuations of strange hadron multiplicity could be sensitive to the equation of state and microscopic structure of strongly interacting matter created at the early stage of high energy nucleus–nucleus collisions. They...
