When results generated within the K-ALFAA are included within a conference presentation or journal publication, we require that all users to provide a copy of that publication to a member of the laboratory staff, who will include the reference in this publications list. A PDF copy of the paper after it appears in publication is sufficient. We require this in order to keep track of the diversity of research that occurs in the facility as well as the number of publications.
