The author is not allowed to withdraw submitted or published article (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 article and works invested by the publisher. Articles may only be withdrawn if they have not been formally published. To withdraw an article, the authors must write a clear and concise letter with an in-depth explanation as to why the article needs to be withdrawn to avoid fine or withdrawal fees. The letter must be signed by all authors. The journal also maintains the right to withdraw an article due to the presence of plagiarism, fraudulent use of data or violations of other ethical codes.
