Quantifying transient spreading dynamics on networks [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2018 Spreading phenomena on networks are essential for the collective dynamics of various natural and technological systems, from information spreading in gene regulatory networks to neural circuits and from epidemics to supply networks experiencing perturbations.

Influence of aggregation on benthic coral reef spatio-temporal dynamics [PDF]
Royal Society Open Science, 2019 Spatial patterning of coral reef sessile benthic organisms can constrain competitive and demographic rates, with implications for dynamics over a range of time scales. However, techniques for quantifying and analysing reefscape behaviour, particularly at

Non-normal parameter blowout bifurcation: an example in a truncated mean field dynamo model [PDF]
, 1997 We examine global dynamics and bifurcations occurring in a truncated model of a stellar mean field dynamo. This model has symmetry-forced invariant subspaces for the dynamics and we find examples of transient type I intermittency and blowout bifurcations

Aggregation and Emergence in Agent-Based Models: A Markov Chain Approach [PDF]
, 2012 We analyze the dynamics of agent--based models (ABMs) from a Markovian perspective and derive explicit statements about the possibility of linking a microscopic agent model to the dynamical processes of macroscopic observables that are useful for a ...

Transient power dynamics in nematic electroconvection
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023 We have observed the transient dynamics in nematic electroconvection during a sudden change in the driving voltage. The steady state dynamics of nematic electroconvection during a constant driving voltage are well characterized examples of spatiotemporal chaos, and thus are useful for the study of chaotic transients.

Journal of Biological Dynamics, 2016 In many existing predator–prey or plant–herbivore models, the numerical response is assumed to be proportional to the functional response. In this paper, without such an assumption, we consider a diffusive plant–herbivore system with Neumann boundary ...

Transient Anomalous Diffusion in Run-and-Tumble Dynamics
Frontiers in Physics, 2019 We study the stochastic dynamics of a particle with two distinct motility states. Each one is characterized by two parameters: one represents the average speed and the other represents the persistence quantifying the tendency to maintain the current ...

Ultrafast Hole Trapping and Relaxation Dynamics in p-Type CuS Nanodisks [PDF]
, 2015 CuS nanocrystals are potential materials for developing low-cost solar energy conversion devices. Understanding the underlying dynamics of photoinduced carriers in CuS nanocrystals is essential to improve their performance in these devices. In this work,
