Fig. 4From: Multiplex flows in citation networksAn example of the ascending flow metric in an excerpt of 22 nodes (60 edges) of our dataset, rooted by a publication by Lorenzo Cornalba. The size of nodes corresponds to their ascending flow in this subgraph. The color of nodes and edges (from blue to red) is actually their ascending flow in the real global dataset — we can see that Hong Liu’s publication has probably been a seed for more knowledge than of its ancestor Lorenzo CornalbaBack to article page
