An author should not in general publish manuscripts describing essentially the same research in more than one journal or primary publication. Elsevier does not view the following uses of a work as prior publication: publication in the form of an abstract; publication as an academic thesis; publication as an electronic preprint. Please note that Cell Press, The Lancet and some society-owned titles have different policies on prior publication. For further information go to: Policies and Ethics for Journal Authors (Multiple, redundant or concurrent publication). For any further clarifications, you can submit your query via our online form
