You might not yet have noticed that since last years the DVCon Europe (2023) has introduced a new category of papers: Research papers. Research papers complement the category of engineering papers. They make a clear contribution to science and research and are reviewed following the scientific standards: at least 3 (double blinded) reviews are made by a scientific program committee, and only papers with an excellent quality and a clear novelty are accepted in the research track.
Research papers is an interesting category for researchers like Ph.D. students that require high visibility of their work: these papers are, among others, indexed via IEEE Xplore. The proceedings of DVCon Europe 2023 are available here: https://ieeexplore.ieee.org/xpl/conhome/10461367/proceeding
