Abstract: Co-authorship networks of neighbouring scientific disciplines, 
i.e. granular (G) media and networks (N) are studied in order to observe 
drastic structural changes in evolving networks. The data is taken from 
arXives. The system is described as coupled networks. By considering the 
1995-2005 time interval and scanning the author-article network evolution 
with a mobile time window, we focus on the properties of the links, as well 
as on the time evolution of the nodes. They can be in three states, N, G or 
multi-disciplinary (M). This leads to drastic jumps in a so-called order 
parameter, i.e. the link proportion of a given type, forming the main 
island, that reminds of features appearing at percolation and during 
metastable (aggregation-desaggregation) processes. The data analysis also 
focuses on the way different kinds (N, G or M) of authors collaborate, and 
on the kind of the resulting collaboration.
