Synchronization Dynamics in the Presence of Coupling Delays and Phase Shifts
David J. Jörg, Luis G. Morelli, Saúl Ares +1
In systems of coupled oscillators, the effects of complex signaling can be captured by time delays and phase shifts. Here, we show how time delays and phase shifts lead to differen…
Mobility-induced persistent chimera states
Gabriela Petrungaro, Koichiro Uriu, Luis G. Morelli
We study the dynamics of mobile, locally coupled identical oscillators in the presence of coupling delays. We find different kinds of chimera states, in which coherent in-phase and…
Nonlinearity arising from noncooperative transcription factor binding enhances negative feedback and promotes genetic oscillations
Iván M. Lengyel, Daniele Soroldoni, Andrew C. Oates +1
We study the effects of multiple binding sites in the promoter of a genetic oscillator. We evaluate the regulatory function of a promoter with multiple binding sites in the absence…
Associative memory on a small-world neural network
Luis G. Morelli, Guillermo Abramson, Marcelo N. Kuperman
We study a model of associative memory based on a neural network with small-world structure. The efficacy of the network to retrieve one of the stored patterns exhibits a phase tra…
Synchronization of Kauffman networks
Luis G. Morelli, Damian H. Zanette
We analyze the synchronization transition for a pair of coupled identical Kauffman networks in the chaotic phase. The annealed model for Kauffman networks shows that synchronizatio…
