Self Tuned Criticality: Controlling a neuron near its bifurcation point via temporal correlations
Juliane T. Moraes, Eyisto J. Aguilar Trejo, Sabrina Camargo +2
Previous work showed that the collective activity of large neuronal networks can be tamed to remain near its critical point by a feedback control that maximizes the temporal correl…
Importance sampling with imperfect cloning for the computation of generalized Lyapunov exponents
Celia Anteneodo, Sabrina Camargo, Raúl O. Vallejos
We revisit the numerical calculation of generalized Lyapunov exponents, (), in deterministic dynamical systems. The standard method consists of adding noise to the dynamics i…
Impact of rough potentials in rocked ratchet performance
S. Camargo, C. Anteneodo
We consider thermal ratchets modeled by overdamped Brownian motion in a spatially periodic potential with a tilting process, both unbiased on average. We investigate the impact of…
Sleep apnea-hypopnea quantification by cardiovascular data analysis
Sabrina Camargo, Maik Riedl, Celia Anteneodo +3
Sleep apnea is the most common sleep disturbance and it is an important risk factor for cardiovascular disorders. Its detection relies on a polysomnography, a combination of divers…
Bridging stylized facts in finance and data non-stationarities
Sabrina Camargo, Silvio M. Duarte Queiros, Celia Anteneodo
Employing a recent technique which allows the representation of nonstationary data by means of a juxtaposition of locally stationary patches of different length, we introduce a com…
Intermingled basins in coupled Lorenz systems
Sabrina Camargo, Ricardo L. Viana, Celia Anteneodo
We consider a system of two identical linearly coupled Lorenz oscillators, presenting synchro- nization of chaotic motion for a specified range of the coupling strength. We verify…
Non-parametric segmentation of non-stationary time series
S. Camargo, S. Duarte Queirós, C. Anteneodo
The non-stationary evolution of observable quantities in complex systems can frequently be described as a juxtaposition of quasi-stationary spells. Given that standard theoretical…
Periodic-orbit analysis and scaling laws of intermingled basins of attraction in an ecological dynamical system
Rodrigo Frehse Pereira, Sabrina Camargo, Sandro Ely de Souza Pinto +2
Chaotic dynamical systems with two or more attractors lying on invariant subspaces may, provided certain mathematical conditions are fulfilled, exhibit intermingled basins of attra…
