Avoiding healthy cells extinction in a cancer model

ÁG López, J Sabuco, JM Seoane, J Duarte… - Journal of theoretical …, 2014 - Elsevier
We consider a dynamical model of cancer growth including three interacting cell populations
of tumor cells, healthy host cells and immune effector cells. For certain parameter choice, the …

When less is more: Partial control to avoid extinction of predators in an ecological model

R Capeans, J Sabuco, MAF Sanjuan - Ecological Complexity, 2014 - Elsevier
Extinction of a species is one of the most dramatic processes in ecology. Here we use an
extended version of the McCann–Yodzis three-species food chain model proposed by …

[PDF][PDF] Controlling chaos of hybrid systems by variable threshold values

D Ito, T Ueta, T Kousaka, J Imura… - … Journal of Bifurcation …, 2014 - repo.lib.tokushima-u.ac.jp
We try to stabilize unstable periodic orbits embedded in a given chaotic hybrid dynamical
system by a perturbation of a threshold value. In conventional chaos control methods, a …

Forcing the escape: Partial control of escaping orbits from a transient chaotic region

G Alfaro, R Capeáns, MAF Sanjuán - Nonlinear Dynamics, 2021 - Springer
A new control algorithm based on the partial control method has been developed. The
general situation we are considering is an orbit starting in a certain phase space region Q …

Beyond partial control: controlling chaotic transients with the safety function

R Capeáns, MAF Sanjuán - Nonlinear Dynamics, 2022 - Springer
Partial control is a technique used in systems with transient chaos. The aim of this control
method is to avoid the escape of the orbits from a region Q of the phase space where the …

Partial control of chaotic transients using escape times

J Sabuco, S Zambrano, MAF Sanjuán - New Journal of Physics, 2010 - iopscience.iop.org
The partial control technique allows one to keep the trajectories of a dynamical system
inside a region where there is a chaotic saddle and from which nearly all the trajectories …

A general method to stabilize unstable periodic orbits for switched dynamical systems with a periodically moving threshold

Y Miino, D Ito, H Asahara, T Kousaka… - International Journal of …, 2018 - Wiley Online Library
In the previous study, a method to control chaos for switched dynamical systems with
constant threshold value has been proposed. In this paper, we extend this method to the …

Safe regions with partial control of a chaotic system in the presence of white Gaussian noise

V Agarwal, J Sabuco, B Balachandran - International Journal of Non-Linear …, 2017 - Elsevier
Noise is present in a wide variety of engineering systems, and it can play a significant role in
influencing system dynamics. Under the influence of noise, it has been shown that the …

Locating and stabilizing unstable periodic orbits embedded in the horseshoe map

Y Miino, D Ito, T Ueta, H Kawakami - International Journal of …, 2021 - World Scientific
Based on the theory of symbolic dynamical systems, we propose a novel computation
method to locate and stabilize the unstable periodic points (UPPs) in a two-dimensional …
