We want to support all researchers to publish. To help those who are unable to meet some, or all, of the cost associated with publishing open access, we operate a transparent waiver policy.
A waiver or partial waiver of author fees may be decided by the editor in case of lack of funding, excessive length of a submitted manuscript or other reasonable reasons provided by the author during the submission.
The author should clearly declare that he asks for a waiver in the comments to the Editor box during their submission.
A waiver is most likely to be denied if it is not asked in this stage. The waiver will have no effect on the review result.
