Enumeration of convex polyominoes using the ECO method [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 ECO is a method for the enumeration of classes of combinatorial objects based on recursive constructions of such classes. In the first part of this paper we present a construction for the class of convex polyominoes based on the ECO method.

Feedback Control Theory in Stochastic Dynamical Systems [PDF]
, 2016 A stochastic dynamical system is a system composed of many interacting components which includes stochastic behavior. Feedback control theory is designed to use information from the current state of the system in order to temper the final state toward ...

Evidence for intermittency in a granular medium: experiments and simulations. [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 We present the first experimental demonstration of intermittency in a granular medium. The medium consists of magnets embedded within spheres. These spheres are placed in a horizontal Petri dish where they roll by virtue of an alternating, homogenous ...

On the set of Fixed Points of the Parallel Symmetric Sand Pile Model [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 Sand Pile Models are discrete dynamical systems emphasizing the phenomenon of $\textit{Self-Organized Criticality}$. From a configuration composed of a finite number of stacked grains, we apply on every possible positions (in parallel) two grain moving ...

Projective subdynamics and universal shifts [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We study the projective subdynamics of two-dimensional shifts of finite type, which is the set of one-dimensional configurations that appear as columns in them.

Optimal Nonlinear Prediction of Random Fields on Networks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 It is increasingly common to encounter time-varying random fields on networks (metabolic networks, sensor arrays, distributed computing, etc.).This paper considers the problem of optimal, nonlinear prediction of these fields, showing from an information ...

A fixed point theorem for Boolean networks expressed in terms of forbidden subnetworks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We are interested in fixed points in Boolean networks, $\textit{i.e.}$ functions $f$ from $\{0,1\}^n$ to itself. We define the subnetworks of $f$ as the restrictions of $f$ to the hypercubes contained in $\{0,1\}^n$, and we exhibit a class $\mathcal{F ...

Bifurcations in Boolean Networks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 This paper characterizes the attractor structure of synchronous and asynchronous Boolean networks induced by bi-threshold functions. Bi-threshold functions are generalizations of standard threshold functions and have separate threshold values for the ...

Interacting active particles and cellular automata: microscopic models of stochastic nonequilibrium systems [PDF]
The broad focus of this thesis is the statistical physics of nonequilibrium systems -- systems which violate the condition of detailed balance. Detailed balance is the property that the probability fluxes between all pairs of states of a system cancel ...

What Is a Macrostate? Subjective Observations and Objective Dynamics [PDF]
, 2003 We consider the question of whether thermodynamic macrostates are objective consequences of dynamics, or subjective reflections of our ignorance of a physical system.
