Analysis of Temporal stability of IN (a) and OUT (b) role components. For each temporal snapshot we indicate with total the number of nodes, with lost the number of nodes that were present in the component during the previous temporal snapshot but are no longer present during the current snapshot, with gained the number of nodes that were not present in the component during the previous temporal snapshot and with stable the number of nodes present during both the previous and current snapshot. For the precise GMT time snapshot dates, see Di Francesco Maesa et al. (2018a)
