Please do not submit revisions as new manuscripts. In addition, reviewers can access the manuscript online, which speeds up the review process. Revised manuscripts should be uploaded via the link provided in the editor's decision letter. Using this system, authors can upload manuscript files (text, figures, videos) directly to our office and check on the status of their manuscripts during the review process. Owing to the volume of manuscripts we receive, all submissions need to be made via our online submission system.
