Notes

The organizers have chosen to allow for a large number of presentations, therefore:
The speakers are requested to aim at a presentation of 20 minutes (i.e., 10-15 slides, max.), allowing for questions to be posed at the end of the presentation.
The session chairs are kindly requested to keep a strict time schedule
^*Posters are on display throughout the whole conference, but the authors are assumed to attend their poster on Tuesday between 14:45 and 15:30h.
