Bio-inspired patterns and discrete breathers in molecular networks

Cyclic Negative Feedback systems (CNF systems) are widely exploited in systems biology to model the sustaining oscillations present in several molecular networks. Furthermore, these systems can display a coexistence of different stable attractors, permitting to suitably describe the differentiating processes arising in living cells. The aim of the manuscript is to characterize, through a spectral based techniques, the localized complex spatio-temporal patterns, such as discrete breathers, occurring in arrays of diffusively coupled CNF systems.
