Welcome to Issue 2 of DFI’s Journal Vol. 15. We are happy to introduce six publications which span a wide mix of manuscript types and technical content. While most published papers in the DFI Journal have historically been research papers and technical case histories, this issue introduces a forum paper and a book review in addition to valuable research publications. Forum papers, a new type of paper to the DFI Journal, encompass a much shorter manuscript style, and can include commentaries, opinions, research highlights (e.g., of work currently underway), and responses to previously published papers. Forum papers do not require a response from the author if they discuss another author’s manuscript. However, should the forum paper be closer to a discussion, and should the author of the discussed manuscript desire to provide a response, the submission will be converted into a formal “discussion.” Forum papers and book reviews first undergo a review within the editorial board, and are only subject to external peer review if the content is found to be technically controversial and/or should the area of expertise discussed in the manuscript lie outside the capacities of the editorial board. Hence the Forum Paper is a unique outlet with much technical and editorial flexibility and will, along with the newly introduced book review, enrich the palette of products offered by the DFI Journal.
