Preliminary version of the Scientific Program, at the 
    time of the release of the II announcement on May 1st.  
    Only the tentative actual speaker is listed, the full 
    list of authors for each contribution will be finalized 
    later and will appear in full (with affiliations and 
    e-mails) both on this page and in the abstract book
    when the registration process will be completed.
