Oscillations in networks composed of Cyclic Negative Feedback systems (CNF systems) are widely used to mimic many periodic phenomena occurring in systems biology. In particular, the possible coexistence of different attractors permits to suitably describe the differentiating processes arising in living cells. The aim of the manuscript is to characterize, through a spectral based techniques, the complex...
Negative feedback control loops are widely used in numerous models of periodic phenomena occurring in systems biology, since they give rise to sustained oscillations. In particular, the possible coexistence of different attractors permits to suitably describe the differentiating processes arising in the cell. The aim of this work is to study coupled systems of such kind through spectral techniques,...
If we consider the regulatory networks used in systems biology, we observe certain regularities in their architecture, namely the occurrence of interaction motifs, i.e. of oriented sub-graphs relating their elements with the same interaction scheme. We propose to describe some of these universal motifs and to study their main dynamical properties especially concerning their robustness (called also...
