Dear Filippo,

I came to an agreement with the publishing company that we will remove the 
article from the library and will, instead, inform about the fact that the 
authors did use the work of others withing citing/marking it properly. The 
exact formulation will be done by the publishing company and I will let you 
know about it.

All the best!
Rainer
