A Retraction is a notice that the paper should not be regarded as part of the scientific literature. Retractions are issued if there is clear evidence that the findings are unreliable, this can be as a result of misconduct or honest error; if the findings have previously been published elsewhere without proper referencing, permission or justification; if the work is plagiarized; or if the work reports unethical research. To protect the integrity of the record, the retracted article is not removed from the online journal, but notice of retraction is given, is made freely available to all readers, and is linked to the retracted article. Retractions can be published by the authors when they have discovered substantial scientific errors; in other cases, the Editors or Publisher may conclude that retraction is appropriate. In all cases, the retraction indicates the reason for the action and who is responsible for the decision. If a retraction is made without the unanimous agreement of the authors, that is also noted. In rare and extreme cases involving legal infringement, the Publisher may redact or remove an article. Bibliographic information about the article will be retained to ensure the integrity of the scientific record.
The author is not allowed to withdraw submitted or published manuscripts (unless there are compelling reasons), because the withdrawal is a waste of valuable resources that editors and reviewers spent a great deal of time processing submitted manuscripts and works invested by the publisher.

If the author still requests withdrawal of his/her manuscript the author will be asked to submit an "Article Withdrawal Form" signed by all authors (or) the corresponding author of the manuscript stating the reasons for manuscript withdrawal. Authors must not assume that their manuscript has been withdrawn until they have received appropriate notification to this effect from the editorial office.

Please contact the journal editor by email and download the "Article Withdrawal form".

However, it is unethical for authors to withdraw a submitted or published manuscript from one journal if it is accepted by another journal.
