Articles in press that have been peer reviewed and accepted for publication by this journal's Editorial Board. The wording might potentially change before it is published. See also: Preprint, Proposal. Journal articles are published in "volume" issues at regular intervals; there may be one or more issues per year. An article will usually be included in these issues on a page by page basis; sometimes only part of an article is printed in a particular issue. An article that has been rejected by a journal can be reprinted with no further action other than removing its original submission date and possibly replacing it with that of the next available issue. This re-submission should be done directly through the journal to which it was originally submitted. It cannot be done through ECSite. The term "journal article" is generally used interchangeably with "research paper". However, their definitions include elements that research papers do not have (for example, abstract, introduction, conclusion, bibliography). "Preprint" is a commonly used term that refers to materials that have not yet been through the rigorous review process of a scientific journal. These materials may be presented in conference proceedings or as departmental or institutional reports. They may also be made available on arXiv or another preprint server.
