The APC is payable if and when a manuscript is accepted for publication after peer review, but before it is published. Authors will be required to pay the mandatory Fee of $1249. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis. Taking into account the time and effort required for a detailed peer review we also reward our regular reviewers with the opportunity to publish without the Rapid Service Fee (pending peer review) for every three reviews completed per calendar year. All articles are published open access.
