Fig. 1: Different network structures inhibit the spreading of failures in complex networks.
From: Network isolators inhibit failure spreading in complex networks
We simulate the impact of a single failing link (red) for different network structures; resulting flow changes are colour coded. a, b Both a weak and a strong interconnectivity can suppress the spreading of failures between two modules of a complex network. c Failure spreading is prevented completely by a network isolator (blue shading); flow changes on the grey links are exactly zero. d The Scandinavian power grid consists of three weakly connected modules, which suppresses failure spreading between the modules44. e The vascular network of a Bursera hollickii leaf contains a strong central vein47, which suppresses failure spreading between the two sides of the leaf. f Same as in (d) but with the addition of two links (blue shading) to create a network isolator. See Methods and caption of Fig. 2 for further information on the graphs used here.
