A memory-based three-state model of competing technology adoption: substitution regimes, multi-homing, and churn
Stefano Scialla, Marco Patriarca, Els Heinsalu +1
Technologies, products, platforms, and behavioral routines often compete through gradual adoption, reinforcement-dependent use, and temporary multi-homing. We formulate a homogeneo…
Threshold model of language competition including the bilingual state
Mikhail V. Tamm, Els Heinsalu, Stefano Scialla +1
We propose a threshold model of language competition which includes intermediate bilingual state. The model is based on the Minett-Wang model but through the introduction of thresh…
Effect of diversity distribution symmetry on global oscillations of networks of excitable units
Stefano Scialla, Marco Patriarca, Els Heinsalu +2
We investigate the role of the degree of symmetry of the diversity distribution in shaping the collective dynamics of networks of coupled excitable units modeled by FitzHugh-Nagumo…
Dynamical equivalence between resonant translocation of a polymer chain and diversity-induced resonance
Marco Patriarca, Stefano Scialla, Els Heinsalu +2
Networks of heterogeneous oscillators are often seen to display collective synchronized oscillations, even when single elements of the network do not oscillate in isolation. It has…
Learning thresholds lead to stable language coexistence
Mikhail V. Tamm, Els Heinsalu, Stefano Scialla +1
We introduce a language competition model that is based on the Abrams-Strogatz model and incorporates the effects of memory and learning in the language shift dynamics. On a coarse…
Diversity-induced decoherence
Marius E. Yamakou, Els Heinsalu, Marco Patriarca +1
We analyze the effect of small-amplitude noise and heterogeneity in a network of coupled excitable oscillators with strong time scale separation. Using mean-field analysis, we unco…
The interplay between diversity and noise in an excitable cell network model
Stefano Scialla, Marco Patriarca, Els Heinsalu
We study the interplay between diversity and noise in a 3D network of FitzHugh-Nagumo elements, with topology and dimensions chosen to model a pancreatic beta-cell cluster, as an e…
Hubs, diversity, and synchronization in FitzHugh-Nagumo oscillator networks: Resonance effects and biophysical implications
Stefano Scialla, Alessandro Loppini, Marco Patriarca +1
Using the FitzHugh-Nagumo equations to represent the oscillatory electrical behavior of beta-cells, we develop a coupled oscillator network model with cubic lattice topology, showi…
