Not sure if can give exact numbers off the bat, especially for those further back. The general ballpark was around 50. I cc. SOC which contains Francesca, Thorsten and Michael, who can fill in some of the blanks better maybe for more recent ones they hosted. I paste below my estimates for each. If anyone else in SOC has better recollections than me please correct the below. I can get more precise numbers further back with a bit of work and fishing, but would be effort and require me tracking down people no longer in field and/or working for me anymore. I will try and do so, as this information can be useful in future for presentations and applications (but not sure how quick I can get during this time in August) – will write Thomas, Daniele, Celia, Michaela & Anita in this regard. Let me know if these ballpark numbers are ok for you for now and for sake of this application? (maybe ok to give a range in each one, if it is an open text form, like e.g. 30-40 or 100-110). All the best, Kareem Meeting 1: closer to 30 (think was a little over) Meeting 2: Perugia was more than twice as large since also had non-BioBrillouin combined so closer >100 I would say Meeting 3: In Porto was I believe about 50 Meeting 4: was online via Exeter. Francesca do you have number here? Meeting 5: Online via Vienna. Maximum at any one time was 110 in room (attendance was higher because free and online) Meeting 6: I believe Thomas mentioned around 50 Meeting 7: Michael correct me if I am wrong, but I think this was also around 50? Meeting 8: Thorsten, I believe you mentioned around 70? From: Stephanie Möllmert <stephanie.moellmert@mpl.mpg.de> Date: Wednesday, 13.

However, the submission needs to be before the 15th of each month. Thank you!

Maybe I misunderstand, would Optica then not serve as a Silver/Gold/Platinum sponsor but something else? (if so, what would they potentially offer and want in return?)

Iâ•˙ve gone through it carefully, but Iâ•˙d appreciate it if you could give it a quick glance and let me know if you spot any typos or mistakes, or any design issues. Iâ•˙ll fix them, and we can add Optica if that works out. Thanks so much!
