Authors are not allowed to withdraw submitted manuscripts, because withdrawal is a waste of valuable resources that editors and referees 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 when the manuscript is still in the peer-reviewing process, the author will have to pay 40 USD per manuscript as a withdrawal penalty. However, it is unethical to withdraw a submitted manuscript from one journal if accepted by another journal.
The withdrawal of the manuscript after the manuscript is accepted for publication: the author will have to pay 60 USD per manuscript. Withdrawal of manuscript is only allowed after withdrawal penalty has been fully paid to the Publisher. If the author doesn't agree to pay the penalty, the author and his/her affiliation will be blacklisted for publication in this journal. Even, his/her previously published articles will be removed from our online system.
