For authors
How do I submit a manuscript?
Prepare your manuscript to the Author Guidelines, then submit it online through the submission system.
Is there a fee to publish?
For publication charges and waivers, write to the editorial office through Contact Us before you submit; the Author Guidelines give the current terms.
How long does peer review take?
The editors first check every manuscript for suitability; manuscripts found suitable are then sent for formal review. See the Peer Review Policy for each step.
What kind of peer review does the journal use?
Double-blind review: manuscripts found suitable are sent to two or more expert reviewers, and reviewers and authors do not know each other's identity, as described in the Peer Review Policy.
How can I follow my manuscript?
Sign in to the journal's submission system with the account you submitted from. It shows the status of your manuscript, and every decision is also sent by email.
Can I submit the same manuscript to more than one journal?
No. A manuscript must not be under consideration anywhere else while it is with the journal. See Publication Ethics.
Who owns the copyright, and how can my article be reused?
Articles are open access and published under the Creative Commons Attribution 4.0 License (CC BY 4.0); copyright stays with the authors. Anyone may share and adapt an article, provided the original work is properly cited. See the Open Access Policy.
