Figure 6.

Synchronization patterns in the Karate club network for different values of parameters. The edges of the Karate club network are shown by solid grey connections. Remote and direct synchrony links with $r_{ij}\mathrm{>0.75}$ are shown by dashed green and red lines, respectively. Clusters of synchronized nodes are indicated by different colors of the full circles. For ω _x = 0.7, δ = 0.2π clusters of remote synchrony start to emerge (panel a). For larger values of the hubs’ natural frequencies ω _x = 1, δ = 0.2π, a large cluster of remotely synchronized nodes appears, as the leaf oscillators of hubs 33 and 34 become synchronized (panel b). Remote synchrony is hardly observed when δ = 0, ω _x = 1 (panel c).
