The accepted paper is the one that has been peer-reviewed. The material should be the same as the final published version, but no copy-editing, typesetting, or copyright marking from the publisher should be included. This is how the vast majority of approved papers appear. Sometimes, however, an author discovers problems with a paper after submitting it for review. In this case, the author has two options: they can either withdraw their paper from consideration by the journal or they can attempt to fix the issues identified by the reviewers. If the authors decide to withdraw their paper, they will send an email to the editor of the journal who will then remove it from further consideration. Authors cannot simply re-submit their paper once they have withdrawn it. If authors choose to work on fixing the issues raised by the reviewers, they will need to provide a detailed explanation of their changes in order to ensure that nothing important was lost during the editing process. For example, if a reviewer points out a problem with experimental results, the authors might want to provide additional data or analysis to support their claims. After making the necessary modifications, the authors will then submit a new version of their paper for evaluation by another set of reviewers. Once all the issues have been resolved to the satisfaction of the editors, the authors will be given the go-ahead to publish their paper.
