Please write your abstracts using a size 12 font and limit the abstract to no more than one full page. Since the selection of oral and poster presentations is extremely selective, we strongly encourage you to make your abstract sufficiently detailed and to include enough results to enable the session chairs to accurately determine the novelty and importance of your contribution. If you would like to put a placeholder abstract into the system while you are refining your abstract please do so (note: the web site enables editing of submitted abstracts).
