Manuscripts should be submitted by one of the authors of the manuscript, the manuscript submission system for our journals. Only electronic PDF (.pdf) or Word (.doc, .docx, .odt, .rtf, .txt) files can be submitted through the manuscript submission system, and there is no page limit. Special characters should not be included in the file name of the main manuscript file. Submissions by anyone other than one of the authors will not be accepted. The submitting author takes responsibility for the manuscript during submission and peer review.
