Biological rhythms generated by a single activator-repressor loop with heterogeneity and diffusion
Pablo Rojas, Oreste Piro, Martin E. Garcia
Common models of circadian rhythms are constructed as compartmental reactions of well mixed biochemicals involving a negative-feedback loop containing several intermediate reaction…
Intermittent chaotic spiking in the van der Pol-FitzHugh-Nagumo system with inertia
Marzena Ciszak, Salvador Balle, Oreste Piro +1
The three-dimensional (3D) Fitzhugh-Nagumo neuron model with inertia was shown to exhibit a chaotic mixed-mode dynamics composed of large-amplitude spikes separated by an irregular…
Geometric phase of spheroidal particles in a fluid flow and its control
Jorge Arrieta, Julyan H. E Cartwright, Oreste Piro +1
We investigate the dynamics of spheroids immersed in the journal bearing flow subject to a contractible non-reciprocal loop. We show how geometric phases appear not only in the pos…
The fluid mechanics of poohsticks
Julyan H. E. Cartwright, Oreste Piro
2019 is the bicentenary of George Gabriel Stokes, who in 1851 described the drag - Stokes drag - on a body moving immersed in a fluid, and 2020 is the centenary of Christopher Robi…
Dynamical systems, celestial mechanics, and music: Pythagoras revisited
Julyan H. E. Cartwright, Diego L. González, Oreste Piro
Gioseffo Zarlino reintroduced the Pythagorean paradigm into Renaissance musical theory. In a similar fashion, Nicolaus Copernicus, Galileo Galilei, Johannes Kepler, and Isaac Newto…
Bursting and excitability in neuromorphic resonant tunneling diodes
Ignacio Ortega, Oreste Piro, Bruno Romeira +1
We study in this paper the dynamics of quantum nanoelectronic resonant tunneling diodes (RTDs) as excitable neuromorphic spike generators. We disclose the mechanisms by which the R…
