The brain can efficiently receive and process weak signals, and reproducing signal
amplification is an important task. We investigate weak signal propagation in a coupled …

Many natural and artificial two-states signaling devices are connected forming networks. The
information-processing potential of these systems is usually related to the response to weak …

Disorder in parameters appears to influence the collective behavior of complex adaptive
networks in ways that might seem unconventional. For instance, heterogeneities may …

Emergent behavior in complex networks can be predicted and analyzed via the mechanism
of spontaneous symmetry-breaking bifurcation, in which solutions of related bifurcation …

This paper is focused on the exploitation of intrinsic nonlinear dynamics toward novel
measurement systems and readout methodologies. In particular, sensors that can be …

It is well known that overdamped unforced dynamical systems do not oscillate. However,
well-designed coupling schemes, together with the appropriate choice of initial conditions …

The occurrence of vibrational resonance is investigated in both classical and quantum
mechanical Morse oscillators driven by a biharmonic force. The biharmonic force consists of …

The rich dynamical behavior stemming from unidirectional coupling in a single array of
overdamped nonlinear elements has, recently, been extensively studied. By adjusting …

Unforced bistable dynamical systems having dynamics of the general form cannot oscillate
(ie switch between their stable attractors). However, a number of such systems subject to …

Dynamical systems that operate near the onset of coupling-induced oscillations can exhibit
enhanced sensitivity to external perturbations under suitable operating parameters. This …
