Families of cubic Thue equations with effective bounds for the solutions

Claude Levesque, Michel Waldschmidt

To each non totally real cubic extension $K$ of $\Q$ and to each generator $α$ of the cubic field $K$ , we attach a family of cubic Thue equations, indexed by the units of $K$ , and…

Symplectic approach to the amplification process in a nonlinear fiber

G. Ferrini, I. Fsaifes, T. Labidi +3

We analyze the amplification processes occurring in a nonlinear fiber, either driven with one or two pumps. After determining the solution for the signal and idler fields resulting…

RNA-based regulation: dynamics and response to perturbations of competing RNAs

Matteo Figliuzzi, Andrea De Martino, Enzo Marinari

The observation that, through a titration mechanism, microRNAs (miRNAs) can act as mediators of effective interactions among their common targets (competing endogenous RNAs or ceRN…

Growth Route Toward III-V Multispectral Solar Cells on Silicon

C. Renard, N. Cherkashin, A. Jaffré +8

To date, high efficiency multijunction solar cells have been developed on Ge or GaAs substrates for space applications, and terrestrial applications are hampered by high fabricatio…

Can one use Mueller-Navelet jets at LHC as a clean test of QCD resummation effects at high energy?

B. Ducloué, L. Szymanowski, S. Wallon

The measurement of azimuthal correlations of Mueller-Navelet jets is generally considered as a decisive test to reveal the effect of BFKL dynamics at hadron colliders. The first ex…

Solving Coupled Composite Monotone Inclusions by Successive Fejér Approximations of Their Kuhn-Tucker Set

Abdullah Alotaibi, Patrick L. Combettes, N. Shahzad

We propose a new class of primal-dual Fejer monotone algorithms for solving systems of com- posite monotone inclusions. Our construction is inspired by a framework used by Eckstein…

The Kardar-Parisi-Zhang equation with spatially correlated noise: a unified picture from nonperturbative renormalization group

Thomas Kloss, Léonie Canet, Bertrand Delamotte +1

We investigate the scaling regimes of the Kardar-Parisi-Zhang equation in the presence of spatially correlated noise with power law decay $D (p) \sim p^{- 2 ρ}$ in Fourier space, usin…

A Fake Split Supersymmetry Model for the 126 GeV Higgs

Karim Benakli, Luc Darmé, Mark D. Goodsell +1

We consider a scenario where supersymmetry is broken at a high energy scale, out of reach of the LHC, but leaves a few fermionic states at the TeV scale. The particle content of th…

Spectral distortions in the cosmic microwave background polarization

Sebastien Renaux-Petel, Christian Fidler, Cyril Pitrou +1

We compute the spectral distortions of the Cosmic Microwave Background (CMB) polarization induced by non-linear effects in the Compton interactions between CMB photons and cold int…

Cosmologically probing ultra-light particle dark matter using 21 cm signals

Kenji Kadota, Yi Mao, Kiyomoto Ichiki +1

There can arise ubiquitous ultra-light scalar fields in the Universe, such as the pseudo-Goldstone bosons from the spontaneous breaking of an approximate symmetry, which can make a…

Phase behavior under the averaging over disorder realizations

E. V. Vakarin, W. Dong, J. P. Badiali

Effects of the averaging over disorder realizations (samples) on the phase behavior are analyzed in terms of the mean field approximation for the random field Ising model with infi…

Turbulent spots in channel flow: an experimental study Large-scale flow, inner structure and low order model

Grégoire Lemoult, Konrad Gumowski, Jean-Luc Aider +1

We present new experimental results on the development of turbulent spots in channel flow. The internal structure of a turbulent spot is measured, with Time Resolved Stereoscopic P…

N=1 SUSY AdS4 vacua in IIB SUGRA on group manifolds

Gautier Solard

We study N=1 compactification of IIB supergravity to AdS4. The internal manifold must have SU(2)-structure. By putting some restrictions on the SU(2) torsion classes, we can perfor…

Topology beyond the horizon: how far can it be probed?

Ophélia Fabre, Simon Prunet, Jean-Philippe Uzan

The standard cosmological model does not determine the spatial topology of the universe. This article revisits the signature of a non-trivial topology on the properties of the cosm…

Transition densities for strongly degenerate time inhomogeneous random models

R. Höpfner, E. Löcherbach, M. Thieullen

In this paper we study the existence of densities for strongly degenerate stochastic differential equations whose coefficients depend on time and are not globally Lipschitz. In the…

Vehicular Inter-Networking via Named Data

Giulio Grassi, Davide Pesavento, Lucas Wang +4

In this paper we apply the Named Data Networking, a newly proposed Internet architecture, to networking vehicles on the run. Our initial design, dubbed V-NDN, illustrates NDN's pro…

The Super-Higgs Mechanism in Fluids

Karim Benakli, Yaron Oz, Giuseppe Policastro

Supersymmetry is spontaneously broken when the field theory stress-energy tensor has a non-zero vacuum expectation value. In local supersymmetric field theories the massless gravit…

Rayleigh-Taylor Instability at Ionization Fronts: Perturbation Analysis

Massimo Ricotti

The linear growth rate of the Rayleigh-Taylor instability (RTI) at ionization fronts is investigated via perturbation analysis in the limit of incompressible fluids. In agreement w…

On Lattices of Regular Sets of Natural Integers Closed under Decrementation

Patrick Cégielski, Serge Grigorieff, Irène Guessarian

We consider lattices of regular sets of non negative integers, i.e. of sets definable in Presbuger arithmetic. We prove that if such a lattice is closed under decrement then it is…

Photoluminescence decay of silicon nanocrystals and Lévy stable distributions

G. Dattoli, K. Gorska, A. Horzela +1

Recent experiments have shown that photoluminescence decay of silicon nanocrystals can be described by the stretched exponential function. We show here that the associated decay pr…
