Recently, there has been a case in which authors who submitted to our journal were asked to provide monetary payment as a condition for publication during the review process. This journal selects and publishes high quality manuscripts through a fair and transparent review process. There will never be an instance in which the authors are required to provide payment, other than the official publication fee. Please be careful and do not comply with these illegal requests. If you receive any such communication, please inform the editor or secretariat office immediately.
