Publication Ethics and Publication Malpractice Statement
Our publication ethics and publication malpractice statement is based on Best Practice Guidelines for Journal Editors of the Committee on Publication Ethics (COPE). More details can be found here: https://publicationethics.org/.
Editors' responsibilities
Editorial Board
The Editorial board consists of the members of the Scientific Organizing Committee. Their names and affiliations as well as updated contact information are listed on the Workshop’s webpage.
Publication decisions
The editor is responsible for deciding which of the papers submitted to the proceedings will be published.
Peer review process
All of a proceedings’ content will be subjected to peer-review. Articles submitted for possible publication are reviewed by the editors. The editors will classify the papers as publishable immediately, publishable with amendments and improvements, or not publishable. The peer-reviewing process must serve the author in improving the paper.
Fair play
Reviews should be conducted objectively. Personal criticism of the author is inappropriate. The editors will evaluate manuscripts without regard to the authors' race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy. The decision will be based on the paper’s importance, originality and clarity, and the study’s validity and its relevance to the proceedings’ scope.
Confidentiality
Any manuscripts received for review must be treated as confidential documents. The editors must not disclose any information about a submitted manuscript to anyone other than the corresponding author, other editorial advisers, and the publisher, as appropriate.
Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted paper will not be used by the editors for their own research purposes without the author's explicit written consent. Editors should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions associated with the papers.
Authors' duties
Authorship of the paper
All listed authors must have made a significant scientific contribution to the study in the paper and approved all its claims. All those who have made significant contributions should be listed as co-authors. The corresponding author ensures that all contributing co-authors and no uninvolved persons are included in the author list. The corresponding author will also verify that all co-authors have approved the final version of the paper and have agreed to its submission for publication.
Originality, plagiarism and acknowledgement of sources
Authors will submit only entirely original works, and will appropriately cite or quote the work and/or words of others. If authors have used their own previously published study as the basis for a submitted manuscript, they are required to cite the previous paper and indicate how their submitted manuscript offers novel contributions beyond those of the previous work.
Disclosure and conflicts of interest
All authors should include a statement disclosing any financial or other substantive conflicts of interest that may be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed.
Open Access Policy
The proceedings are freely available online. Authors are required to agree with this open access policy which enables unrestricted access and reuse of all published articles.

Instructions for Authors
The author instructions are available in the Letters LaTeX Template.
- Authors must prepare their submissions using the provided LaTeX template, which follows the letters class format. Submissions that do not adhere to the template will be returned for revisions.
- Letters focus on concise, rapid communications and should adhere to strict page limits, typically not exceeding 4 pages, including references, figures, and tables. Exceptions may be considered for extraordinary events or groundbreaking results, where additional length is justified.
- Submissions should be sent as a zip file containing the following: the LaTeX (.tex) file, the bibliography (.bib) file, and all figures in high-resolution formats (e.g., .png, .jpg, .eps).
- Submissions should be made using the submission form below.
- Once accepted, letters will be published individually and each paper will receive a DOI number.
- The journal publishes two issues per year, and accepted letters will appear in the next scheduled issue.
- All submissions undergo a rigorous peer review process to ensure quality and relevance.
