## Abstracts

Invited lectures are expected to be 40 minutes long, plus 5 minutes for a discussion. Contributed talks are expected to be 15-20 minutes long plus 5 minutes for questions.

NOTE: Due to limited capacity we might be forced to make a selection of contributed talks from the submitted abstracts. In case this situation occurs, the remaining abstracts will be offered a poster presentation.
