Crenelated fast oscillatory outputs of a twodelay electrooptic oscillator.
Physical Review E 85(22):026206 (2012) PMID 23003847
We investigate both experimentally and theoretically. Of particular physical interest are the transitions to various crenelated fast timeperiodic oscillations, prior to the onset of chaotic regimes. The twodelay problem is described mathematically by two coupled delaydifferential equations, which... 
Distinguishing dynamics using recurrencetime statistics.
Physical Review E 85(22):026217 (2012) PMID 23003857
The probability densities of the mean recurrence time, which is the average time needed for a system to recur to a previously visited neighborhood, are investigated in various dynamical regimes and are found to be in agreement with those of the finitetime Lyapunov exponents. The imp... 
Stochastic tipping points in climate dynamics.
Physical Review E 85(22):027101 (2012) PMID 23003906
A crucial question recently raised in climate dynamics concerns abrupt climate transitions: Are they due to a tipping point (TP) being exceeded, or is fast noisy dynamics the cause of their excitation? In this respect, a case study based on a loworder ocean model is developed to sho... 
Diffusional screening in treelike spaces: An exactly solvable diffusionreaction model.
Physical Review E 85(11):011115 (2012) PMID 23003370
We provide analytic conditions for the emergence of a plateau in the currenta region of maximum insensitivity of the current to variations in either the reaction rate (membrane permeability) or the diffusivity. The occurrence of such a plateau is associated with a partial screening regime wherein m... 
Nonequilibrium densitymatrix description of steadystate quantum transport.
Physical Review E 85(11):011126 (2012) PMID 23003381
We investigate the stationary nonequilibrium density matrix of current carrying nonequilibrium steady states of inbetween quantum systems that are connected to reservoirs. We describe the analytical procedure to obtain the explicit result for the reduced density matrix of quantum transport when the... 
Powerlaw behavior in a cascade process with stopping events: A solvable model.
Physical Review E 85(11):011145 (2012) PMID 23003400
The present paper proposes a stochastic model to be solved analytically, and a powerlawlike distribution is derived. This model is formulated based on a cascade fracture with the additional effect that each fragment at each stage of a cascade ceases fracture with a certain probabil... 
Corticothalamic dynamics: Structure of parameter space, spectra, instabilities, and reduced model.
Physical Review E 85(11):011910 (2012) PMID 23003444
Linear instabilities are analyzed in a physiologically based meanfield corticothalamic model and a reducedparameter model derived from it. In both models, the stable zone corresponding to normal arousal states is bounded by a series of surfaces demarcating the onsets of instabiliti... 
Statistical physics approach to dendritic computation: The excitablewave meanfield approximation.
Physical Review E 85(11):011911 (2012) PMID 23003445
We analytically study the inputoutput properties of a neuron whose active dendritic tree, modeled as a Cayley tree of excitable elements, is subjected to Poisson stimulus. Both singlesite and twosite meanfield approximations incorrectly predict a nonequilibrium phase transition which is not allo... 
Leasteffort trajectories lead to emergent crowd behaviors.
Physical Review E 85(12):016110 (2012) PMID 23003478
We propose a simple and intuitive formulation of these rules based on biomechanical measurements and the principle of least effort. We present a constrained optimization method to compute collisionfree paths of minimum caloric energy for each agent, from which collective crowd behaviors can be repr... 
Competition of strength and stress disorder in creep rupture.
Physical Review E 85(12):016116 (2012) PMID 23003484
We show that the interplay of threshold disorder and the inhomogeneous stress field gives rise to a rich dynamics with intriguing aspects. In the model, fibers fail either due to immediate breaking or to a slow damage process. When the disorder is strong, a large amount of damage occurs, which is ra...
