For each accepted paper, at least one author or 
					qualified proxy needs to register for attending the 
					conference, and present the paper in the assigned session, 
					either in an oral or as a poster. Publisher reserves the 
					right to exclude a paper from distribution after the 
					conference, if the paper is not presented by the author at 
					the conference. No refund of the paid fees may be claimed by 
					the no show author.
					
					For poster sessions, if the speaker is not present in front 
					of the poster for most of the time during the poster 
					session, this also implies the paper was not presented.
					
					The presenter should start all necessary procedures and 
					approvals (e.g., travel funding, visa application) after 
					receiving notification that the paper is accepted for the 
					conference.
					
					If the authors have, or anticipate, unforeseen circumstances 
					endangering or preventing the presentation, they should 
					notify the conference secretary as soon as possible with 
					proof of their restriction. Substitute presenters may be 
					possible or, depending on conference resources, other 
					accommodations may be available, such as a remote 
					presentation or pre-recorded video.
