Sessions with less than 5 abstracts after the abstract deadline will automatically be cancelled, and abstracts in withdrawn sessions will be (re)assigned to sessions having a similar or close topic.

Sessions that receive more than 5, but less than 15 abstracts, or are very similar in scope can be merged. In such a case, conveners need to update the title, abstract, and list of conveners (max 6) of the new, resulting session.

The Scientific and Organizing Committees will schedule all sessions and conveners will be informed by email about the time and room assigned to their session. Conveners are encouraged to organize their sessions considering and promoting under-represented demographics, in particular including: (i) multiple countries and institutes, (ii) different career stages, with particular attention to the participation of early career scientists, and (iii) different genders and all other forms of diversity.

• Oral blocks (1 hr each) will be assigned depending on the number of abstracts received in the session.
• Oral presentations will be 15 min each (max 30 min. in case of keynote speakers), including questions (12-min-presentations +3 min for questions is suggested).
• Conveners can schedule no more than one keynote speaker per time block.
• If for some reason none of the conveners aim to be present, a chairperson needs to be appointed to act as a convener.
• Conveners are encouraged to avoid presenting their own work as a speaker in a session they convene.
