Once the corresponding author has confirmed to withdraw the submitted article, the author has to communicate with the Editor in Chief via e-mail. A manuscript withdrawal form will be sent to the author’s email following which all the respective authors should sign and express their interest for withdrawal. Upon receiving the completed form from the corresponding author, further processing of the article will be stopped. No processing charges will be collected if the article is withdrawn within 7 days of submission. After this period, if the author requests for withdrawal, the article processing charges (APC) need to be paid by the author.
