The SOC will evaluate the abstracts and communicate to the authors whether they have an oral or poster contribution before April 20. Abstracts submitted after March 15 will be automatically designated as poster contributions. Total word count is limited to 3000 characters including spaces. Please take this into consideration when submitting your abstract. No exceptions will be made to the number of characters limit. Please send your abstract in plain text using LaTeX encoding.
