The authors are required to pay the Article Processing Charge (APC) for publishing with the journal to cover the cost incurred in processing the manuscripts in order to ensure the contents are freely available and to maintain publishing quality. The manuscript processing includes peer review, copy-editing, typesetting, publishing, content depositing and archiving processes. An invoice of APC will be issued after a paper has been accepted, where authors are advised to pay the APC within one week to avoid delay in publication.

In the event that authors insist to withdraw a submission on unethical and unreasonable grounds, a submission withdrawal fee at 30% of the prevailing Article Processing Charge will be levied on the authors. In general, the editors of Bio-Byword Scientific consider the following *unethical and unreasonable reasons* of withdrawing a submission:

• Unaware of the Article Processing Charge payable after paper acceptance (or reluctant to pay Article Processing Charge). Authors are advised to find out the publication fees associated with the journal before making a decision to submit. It is unethical to submit and proceed with the editorial process for a submission under consideration for publication if authors do not have plans of paying the Article Processing Charge upon acceptance.
• Do not want to make all research data or findings available to the journal. Before a submission is made, authors are responsible to check whether the research data or findings presented in manuscript are compatible with their desired journal and/or type of submission they intend to make. There are no defined criteria as to how much data or findings should be published in a paper but it is our belief that studies in scientific and technological principles take sufficient data to make precise and accurate interpretation from experiments. Thus, it is in authors’ best interest to provide, present and publish all relevant data and findings.
• Wanting to submit to a higher- or lower-impact journal. It’s the authors’ responsibility to vet the journal background before making a decision to submit. Making a submission to the journal is comparable to admitting that the quality and standard of the submission match with that of the journal.
