Fig. 7From: Multiplex flows in citation networksComparison of direct citations of four publications with h-index=6. The top node is one original publication, and all other nodes its citing nodes. a Comparison of the general ascending flows with two extreme values: left ID9204026 (flow=425.4), right ID9201019 (flow=11.2). b Comparison of 2−flows with two extreme values: left ID9201079 (2−flow=2.3), right ID9201058 (2−flow=21.6). Relative node size (between couples of pictures) corresponds to h-index values for each node. Node color, from blue to red, corresponds to, a ascending flow, b 2-flowBack to article page
