Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.
  • The submission has not been previously published, nor is it before another journal for consideration (or an explanation has been provided in Comments to the Editor).
  • The submission file uses the template available on the website.
  • All manuscripts are the original work of authors and not evidence plagiarism.
  • The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines. Authors ensure that every manuscript submitted to the journal has been read and corrected for English clarity, grammar and spelling; this applies particularly to authors whose first language is not English.
  • The authors have prepared two versions of the manuscript – one containing the authors details, the other anonymized.


Please check complying with the requirements of this template.
