One of the major advantage of the synchrony alignment function is the ability to combine the network structure with the allocation of natural frequencies. The effect of frequency allocation on the synchrony of NoNs (N1 = N2 = 50) with different subnetwork topologies is shown in Figures 4D–G. Here the natural frequencies, ωi, are reallocated depending on the node degree, ki: ωi is sorted so that |ωi-ω¯| either ascends or descends with ki. In the former case, outlying frequencies are allocated at the hub nodes, the first three of which are the connector nodes of the NoN. Contrarily, in the latter case, ωi≈ω¯ for the hub nodes, and the outlying frequencies are allocated at the low-degree nodes. Analyses reveal that, in all subnetwork topologies, synchrony increases when outlying frequencies are allocated at the hubs (connector nodes). The direct interaction of outlying frequencies averages ωi and allows them to oscillate at near ω¯. In contrast, when the outliers are placed at low-degree nodes, the cancelation does not occur and a group of nodes that oscillate away from ω¯ is formed, resulting
