First exit times of solutions of stochastic differential equations driven by multiplicative Levy noise with heavy tails [PDF]
, 2012 In this paper we study first exit times from a bounded domain of a gradient dynamical system $\dot Y_t=-\nabla U(Y_t)$ perturbed by a small multiplicative L\'evy noise with heavy tails.

Investigating stochastic solutions for fourth order dispersive NLSE with quantic nonlinearity
AIMS Mathematics, 2023 In this paper, the stochastic fourth order nonlinear Schrödinger equation with quantic nonlinearity and affected by multiplicative noise is considered. This model is used to mimic the wave propagation through optical fibers.

Noise removal from multiple MRI images [PDF]
Journal of Digital Imaging, 1994 We introduce a novel technique for magnetic resonance image (MRI) restoration, using a physical model (spin equation). We determine a set of three basis images (proton density and nuclear relaxation times) from the MRI data using a nonlinear optimization method, and use those images to obtain restorations of the original image.

Mesoscopic description of the annealed Ising model and Multiplicative noise
, 1998 A new type of Langevin equation exhibiting a non trivial phase transition associated with the presence of multiplicative noise is introduced. The equation is derived as a mesoscopic representation of the microscopic annealed Ising model (AIM) proposed by

Transient behavior of a population dynamical model [PDF]
, 2004 The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with the environment.

Multiplicative noise, fast convolution and pricing [PDF]
Quantitative Finance, 2012 In this work we detail the application of a fast convolution algorithm computing high dimensional integrals to the context of multiplicative noise stochastic processes. The algorithm provides a numerical solution to the problem of characterizing conditional probability density functions at arbitrary time, and we applied it successfully to quadratic and

Multiplicative Noise: Applications in Cosmology and Field Theory
, 1993 Physical situations involving multiplicative noise arise generically in cosmology and field theory. In this paper, the focus is first on exact nonlinear Langevin equations, appropriate in a cosmologica setting, for a system with one degree of freedom ...
