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.
