Localized patterns and hole solutions in one-dimension extended sytem
, 2005 The existence, stability properties, and bifurcation diagrams of localized patterns and hole solutions in one-dimensional extended systems is studied from the point of view of front interactions.

Stationary propagation of a wave segment along an inhomogeneous excitable stripe
New Journal of Physics, 2014 We report a numerical and theoretical study of an excitation wave propagating along an inhomogeneous stripe of an excitable medium. The stripe inhomogeneity is due to a jump of the propagation velocity in the direction transverse to the wave motion ...

The Grounds For Time Dependent Market Potentials From Dealers' Dynamics
, 2007 We apply the potential force estimation method to artificial time series of market price produced by a deterministic dealer model. We find that dealers' feedback of linear prediction of market price based on the latest mean price changes plays the ...

Nucleation of reaction-diffusion waves on curved surfaces
New Journal of Physics, 2014 We study reaction-diffusion waves on curved two-dimensional surfaces, and determine the influence of curvature upon the nucleation and propagation of spatially localized waves in an excitable medium modelled by the generic FitzHugh–Nagumo model.

The Bi-Hamiltonian Structure of the Short Pulse Equation
, 2006 We prove the integrability of the short pulse equation derived recently by Sch\"afer and Wayne from a hamiltonian point of view. We give its bi-hamiltonian structure and show how the recursion operator defined by the hamiltonian operators is connected ...

High intermodulation gain in a micromechanical Duffing resonator
, 2005 In this work we use a micromechanical resonator to experimentally study small signal amplification near the onset of Duffing bistability. The device consists of a PdAu beam serving as a micromechanical resonator excited by an adjacent gate electrode.

Advances in photonic reservoir computing
Nanophotonics, 2017 We review a novel paradigm that has emerged in analogue neuromorphic optical computing. The goal is to implement a reservoir computer in optics, where information is encoded in the intensity and phase of the optical field.

Chaotic diffusion of particles with finite mass in oscillating convection flows
, 2002 Deterministic diffusion in temporally oscillating convection is studied for particles with finite mass. The particles are assumed to obey a simple dissipative dynamical system and the particle diffusion is induced by the strange attractor.

Validity of the Brunet-Derrida formula for the speed of pulled fronts with a cutoff
, 2007 We establish rigorous upper and lower bounds for the speed of pulled fronts with a cutoff. We show that the Brunet-Derrida formula corresponds to the leading order expansion in the cut-off parameter of both the upper and lower bounds.
