August 5, 2026: PACT Registration Requirement
Each accepted paper requires one full conference registration, regardless of who presents
the paper. A full registration is required for each accepted paper. If an author has
multiple accepted papers, a separate full registration is required for each paper. If the
registered presenter is unable to attend (e.g., due to visa issues), the authors must
arrange for a substitute presenter. Papers that do not meet the registration requirement
or are not presented at the conference will be removed from the proceedings.
