Material under consideration in APP must be original and not submitted elsewhere for publication unless the corresponding author is provided with a rejection letter for the respective manuscript. We greatly encourage publishing a part of work from Ph.D. or thesis in APP.
If the author wishes to submit part of the contribution in APP that has already been published in another or is still under consideration, all such details must be specified within the cover letter. This manuscript can only be considered if the results and conclusions are not the same as the other published study. The author must provide complete copyright details from the previous publisher in case of re-using a figure that has already been published elsewhere.
