Stability analysis of a noise-induced Hopf bifurcation
Kirone Mallick, Philippe Marcq
We study analytically and numerically the noise-induced transition between an absorbing and an oscillatory state in a Duffing oscillator subject to multiplicative, Gaussian white n…
Homogeneous and Scalable Gene Expression Regulatory Networks with Random Layouts of Switching Parameters
D. Volchenkov, R. Lima
We consider a model of large regulatory gene expression networks where the thresholds activating the sigmoidal interactions between genes and the signs of these interactions are sh…
Combination of CDF and D0 Results on W Boson Mass and Width
V. M. Abazov
The results based on 1992-95 data (Run 1) from the CDF and DO experiments on the measurements of the W boson mass and width are presented, along with the combined results. We repor…
Preliminary results from a simulation of quenched QCD with overlap fermions on a large lattice
Federico Berruto, Nicolas Garron, Christian Hoelbling +3
We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at beta=6 on an 18^3x64 lattice. We calculate quark propagators for a single source p…
Integrability versus separability for the multi-centre metrics
Galliano Valent
The multi-centre metrics are a family of euclidean solutions of the empty space Einstein equations with self-dual curvature. For this full class, we determine which metrics do exhi…
Photo--assisted current and shot noise in the fractional quantum Hall effect
A. Crepieux, P. Devillard, T. Martin
The effect of an AC perturbation on the shot noise of a fractional quantum Hall fluid is studied both in the weak and the strong backscattering regimes. It is known that the zero-f…
On the noise-induced passage through an unstable periodic orbit I: Two-level model
Nils Berglund, Barbara Gentz
We consider the problem of stochastic exit from a planar domain, whose boundary is an unstable periodic orbit, and which contains a stable periodic orbit. This problem arises when…
Observation of Diffractively Produced W and Z Bosons in pbar-p Collisions at root-s = 1800 GeV
D0 collaboration, V. M. Abazov
Using the D0 detector, we have observed events produced in pbar-p collisions that contain W or Z bosons in conjunction with very little energy deposition (``rapidity gaps'') in lar…
Convergence to equilibrium for finite Markov processes, with application to the Random Energy Model
Pierre MATHIEU, Pierre PICCO
We estimate the distance in total variation between the law of a finite state Markov process at time t, starting from a given initial measure, and its unique invariant measure. We…
Tunneling effects between tori in double wells
Michel Rouleux
We consider tunneling between 2 symmetric potential wells for a 2-d Schrodinger operator, in the case of eigenvalues associated with quasi-modes supported on KAM or Birkhoff tori.
Vanishing of the conformal anomaly for strings in a gravitational wave
C. Duval, Z. Horvath, P. A. Horvathy
Using the non-symmetric-connection approach proposed by Osborn, we demonstrate that, for a bosonic string in a specially chosen plane-fronted gravitational wave and an axion backgr…
A "general boundary" formulation for quantum mechanics and quantum gravity
Robert Oeckl
I propose to formalize quantum theories as topological quantum field theories in a generalized sense, associating state spaces with boundaries of arbitrary (and possibly finite) re…
Schroedinger's cat and the clock: Lessons for quantum gravity
Robert Oeckl
I review basic principles of the quantum mechanical measurement process in view of their implications for a quantum theory of general relativity. It turns out that a clock as an ex…
Law of large numbers for the asymmetric simple exclusion process
E. Andjel, P. A. Ferrari, A. Siqueira
We consider simple exclusion processes on Z for which the underlying random walk has a finite first moment and a non-zero mean and whose initial distributions are product measures…
Poisson Hypothesis for information networks (A study in non-linear Markov processes)
Alexander Rybko, Senya Shlosman
In this paper we prove the Poisson Hypothesis for the limiting behavior of the large queueing systems in some simple ("mean-field") cases. We show in particular that the correspond…
Phase-Field Approach for Faceted Solidification
Jean-Marc Debierre, Alain Karma, Franck Celestini +1
We extend the phase-field approach to model the solidification of faceted materials. Our approach consists of using an approximate gamma-plot with rounded cusps that can approach a…
Isolated electrons and muons in events with missing transverse momentum at HERA
H1 Collaboration
A search for events with a high energy isolated electron or muon and missing transverse momentum has been performed at the electron-proton collider HERA using an integrated luminos…
Effects of parametric noise on a nonlinear oscillator
Kirone Mallick, Philippe Marcq
We study a model of a nonlinear oscillator with a random frequency and derive the asymptotic behavior of the probability distribution function when the noise is white. In the small…
Isoperimetry and heat kernel decay on percolation clusters
Pierre Mathieu, Elisabeth Remy
We prove that the heat kernel on the infinite Bernoulli percolation cluster in Z^d almost surely decays faster than t^{-d/2}. We also derive estimates on the mixing time for the ra…
