Each single network or a subnetwork of a NoN is composed of N = 50 nodes in most analyses, while networks with N = 1,000 nodes are employed to discuss the generalizability of the findings. In either case, the nodes are interconnected with undirected links with an average degree of six (k = 6). K is sampled at intervals of 0.05 and 0.1 for the single network and NoN, respectively. For each K, 250 networks with different sets of the adjacency matrix Aij, initial phase ϕi(0), and natural frequency ωi are sampled.
