Figure 6

Scientists’ h-index versus tie strength. In this figure, we present a more detailed analysis of the relationship from Fig. 5a, which shows the data averaged over all scientists in the studied collaboration network, regardless of the stage of their scientific career. Here we divide scientists into groups in which everyone has the same number of total publications and the same number of co-authors (see the colour map in the figure). The more homogeneous conditions thus established allow us to clearly confirm earlier findings. In particular, as one can see in the small graphs on the right side of the colour map, regardless of the choice of the homogeneous group of scientists their h-index always decreases with increasing average asymmetric tie strength.
