  Quenching of oscillations, namely amplitude and oscillations death, is an
emerging phenomenon exhibited by many real-world complex systems. Here, we
introduce a scheme that combines dissimilar couplings and repulsive feedback
links for the interactions of Stuart Landau oscillators and analytically
derives the conditions required for the amplitude death. Importantly, this
analysis is independent of the network size, presents a generalized approach to
calculate the stability conditions for various different coupling schemes, and
befits for non-identical oscillators as well. Last, we discuss the similarities
of the quenching of oscillations phenomenon with the postictal generalized EEG
suppression in convulsive seizures.
