Complementary cumulative distribution function (CCDF) of activities. At the top CCDF of the empirical firm activities, measured for two representative industrial sectors (from the SDC data set, [19] Supplementary information). At the bottom CCDF of the empirical author activities, measured for two representative co-authorship networks (from the APS-MSAS data sets). We considered for 4 different time windows Δt of 1, 5, 10 and 26 years.
