Global bifurcation in a virus, defective genomes, satellite RNAs tripartite system: breakdown of a coexistence quasi-neutral curve
Oriol Llopis-Almela, J. Tomas Lazaro, Santiago F. Elena +1
The dynamics of wild-type (wt) RNA viruses and their defective viral genomes (DVGs) have been extensively studied both experimentally and theoretically. This research has paid spec…
Functional shift-induced degenerate transcritical Neimark-Sacker bifurcation in a discrete hypercycle
E. Fontich, A. Guillamon, J. Perona +1
In this article we investigate the impact of functional shifts in a time-discrete cross-catalytic system. We use the hypercycle model considering that one of the species shifts fro…
Host-virus evolutionary dynamics with specialist and generalist infection strategies: bifurcations, bistability and chaos
Anel Nurtay, Matthew G. Hennessy, Lluís Alsedà +2
In this work we have investigated the evolutionary dynamics of a generalist pathogen, e.g. a virus population, that evolves towards specialisation in an environment with multiple h…
Dynamics in a time-discrete food-chain model with strong pressure on preys
Lluís Alsedà, José Tomás Lázaro, Ricard Solé +2
Ecological systems are complex dynamical systems. Modelling efforts on ecosystems' dynamical stability have revealed that population dynamics, being highly nonlinear, can be govern…
Finite-time scaling in local bifurcations
Alvaro Corral, Lluis Alseda, Josep Sardanyes
Finite-size scaling is a key tool in statistical physics, used to infer critical behavior in finite systems. Here we use the analogous concept of finite-time scaling to describe th…
Population dynamics of synthetic Terraformation motifs
Ricard Sole, Raul Montanez, Salva Duran-Nebreda +3
Ecosystems are complex systems, currently experiencing several threats associated with global warming, intensive exploitation, and human-driven habitat degradation. Such threats ar…
Activation of effector immune cells promotes tumor stochastic extinction: A homotopy analysis approach
Josep Sardanyés, Carla Rodrigues, Cristina Januário +3
In this article we provide homotopy solutions of a cancer nonlinear model describing the dynamics of tumor cells in interaction with healthy and effector immune cells. We apply a s…
Dynamics and bifurcations in a simple quasispecies model of tumorigenesis
V. Castillo, J. Tomas Lazaro, J. Sardanyes
Cancer is a complex disease and thus is complicated to model. However, simple models that describe the main processes involved in tumoral dynamics, e.g., competition and mutation,…
Red Queen Coevolution on Fitness Landscapes
Ricard V. Sole, Josep Sardanyes
Species do not merely evolve, they also coevolve with other organisms. Coevolution is a major force driving interacting species to continuously evolve ex- ploring their fitness lan…
