Journal of Biological Dynamics, 2016 In biochemical networks transient dynamics plays a fundamental role, since the activation of signalling pathways is determined by thresholds encountered during the transition from an initial state (e.g. an initial concentration of a certain protein) to a

Devaney chaos in non-autonomous discrete systems
, 2016 This paper is concerned with Devaney chaos in non-autonomous discrete systems. It is shown that in its definition, the two former conditions, i.e., transitivity and density of periodic points, in a set imply the last one, i.e., sensitivity, in the case ...

Continuous data assimilation for the Richards equation of unsaturated flow: A computational study
Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.Abstract Azouani–Olson–Titi data assimilation (often referred to as AOT, after its authors) is a computationally‐efficient algorithm that has been shown analytically and computationally to recover the true solution for a wide variety of regimes exponentially fast in time, in addition to being robust with respect to noisy data, stochastic forcing, and ...

The Ellis semigroup of a nonautonomous discrete dynamical system
, 2016 We introduce the {\it Ellis semigroup} of a nonautonomous discrete dynamical system $(X,f_{1,\infty})$ when $X$ is a metric compact space. The underlying set of this semigroup is the pointwise closure of $\{f\sp{n}_1 \, |\, n\in \mathbb{N}\}$ in the ...

Global φ-attractor for a modified 3D Bénard system on channel-like domains
Nonautonomous Dynamical Systems, 2014 In this paper we prove the existence of a global '-attractor in the weak topology of the natural phase space for the family of multi-valued processes generated by solutions of a nonautonomous modified 3D Bénard system in unbounded domains for which ...

Stimuli‐Responsive Chemical Systems That Mimic Biological Dynamics
Chemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.Chemists are designing synthetic systems that mimic life's dynamic behaviors, such as motion, sensing, adaptation, and compartmentalization, by integrating reaction networks with stimuli like light, pH, and chemical fuels. This mini‐review surveys molecular machines, responsive materials, nucleic acid networks, and artificial cells, highlighting how ...

Forecasting the forced van der Pol equation with frequent phase shifts using Reservoir Computing
Machine Learning with ApplicationsWe tested the performance of reservoir computing (RC) in predicting the dynamics of a specific nonautonomous dynamical system. Specifically, we considered a van der Pol oscillator subjected to a periodic external force with frequent phase shifts.
