Authors should submit their manuscripts for the special issue by emailing them as an attachment to specialissue@hillpublish.com or by using the online submission system. The manuscript should be submitted by one of the authors, and submissions by anyone other than the authors will not be accepted. Additionally, the submitted manuscript should include a cover letter that specifies the special issue to which the manuscript is being submitted.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). The submitted papers should be properly formatted and written in fluent English. All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Guidelines page.
