Dynamic range of hypercubic stochastic excitable media [PDF]

open access: yes, 2008
We study the response properties of d-dimensional hypercubic excitable networks to a stochastic stimulus. Each site, modelled either by a three-state stochastic susceptible-infected-recovered-susceptible system or by the probabilistic Greenberg-Hastings ...

Speckle noise reduction techniques for high-dynamic range imaging [PDF]

open access: yes, 2007
High-dynamic range imaging from space in the visible, aiming in particular at the detection of terrestrial exoplanets, necessitates not only the use of a coronagraph, but also of adaptive optics to correct optical defects in real time.

Dynamic fluctuations in a Short-Range Spin Glass model [PDF]

open access: yes, 1995
We study the dynamic fluctuations of the soft-spin version of the Edwards-Anderson model in the critical region for $T\rightarrow T_{c}^{+}$. First we solve the infinite-range limit of the model using the random matrix method.
