Some authors have requested that articles be removed from the publication process after submission. In some cases, retraction requests are made the same day they are mailed, but in most cases, requests are made much later when the only day the letters are published is in the book. Withdrawing manuscripts from publications wastes valuable resources and the significant effort of editors, reviewers, and editorial staff to complete manuscripts.

In order to avoid withdrawal, we would like to thank authors, especially the first author and the corresponding author, on the following set of topics before submitting their articles to the Medwin Publisher’s journal.
