Stochastic analysis of dimerization systems [PDF]
Physical Review E, 2009 The process of dimerization, in which two monomers bind to each other and form a dimer, is common in nature. This process can be modeled using rate equations, from which the average copy numbers of the reacting monomers and of the product dimers can then be obtained. However, the rate equations apply only when these copy numbers are large. In the limit

Optimal Maintenance Policy for a Technical System Subject to Hidden Faults and Randomly Occurring Hazards [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 The paper presents a method of finding the optimal time between inspections for a system subject to degradation-related faults which make the system vulnerable to randomly occurring external hazards that may cause its damage.

Mathematical and Experimental Model of Neuronal Oscillator Based on Memristor-Based Nonlinearity
Mathematics, 2023 This article presents a mathematical and experimental model of a neuronal oscillator with memristor-based nonlinearity. The mathematical model describes the dynamics of an electronic circuit implementing the FitzHugh–Nagumo neuron model.

Stochastic Port-Hamiltonian Systems
Journal of Nonlinear Science, 2022 AbstractIn the present work we formally extend the theory of port-Hamiltonian systems to include random perturbations. In particular, suitably choosing the space of flow and effort variables we will show how several elements coming from possibly different physical domains can be interconnected in order to describe a dynamic system perturbed by general ...

Equivalences between stochastic systems [PDF]
Journal of Physics A: Mathematical and General, 1995 Time-dependent correlation functions of (unstable) particles undergoing biased or unbiased diffusion, coagulation and annihilation are calculated. This is achieved by similarity transformations between different stochastic models and between stochastic and soluble {\em non-stochastic} models.

On the Theory of Unsteady-State Operation of Bulk Continuous Crystallization
Crystals, 2022 Motivated by an important application in the chemical and pharmaceutical industries, we consider the non-stationary growth of a polydisperse ensemble of crystals in a continuous crystallizer.
