Before revision:  In this manner, we discretize the amplitude of coupled time-series and investigate relative simultaneous locations of the corresponding amplitudes(nodes). The transmissions between simultaneous amplitudes are clarified by edges in the network.
After revision:  In this manner, we discretize the amplitude of coupled time-series and investigate relative simultaneous locations of those amplitudes. Each segment of a discretized amplitude is considered as a node. The simultaneity of the amplitudes of the two time-series is considered as the edges in the network.
