3.1 Before you submit

·         Manuscripts are submitted only through the DergiPark system at dergipark.org.tr/en/pub/adenj. Submissions by e-mail are not processed.

·         The manuscript must be original, must not have been published previously, and must not be under consideration elsewhere. Preprints deposited on a recognised server (e.g. arXiv, TechRxiv) are acceptable and must be declared with their DOI.

·         All authors must have read and approved the submitted version and must meet the ICMJE authorship criteria.

·         ORCID iDs are mandatory for all authors.

·         Manuscripts derived from a thesis, dissertation, or conference paper must state this explicitly on the title page, including the institution, year, and — for conference papers — the extent of new material.

3.2 Language

·         The primary language of the journal is English. Manuscripts in Turkish are also accepted.

·         Every manuscript, in either language, must include an English title, English abstract, and English keywords. This is a condition of the journal’s international indexing strategy and is not waived.

·         Turkish-language manuscripts must additionally include a Turkish title, abstract, and keywords. Authors of English-language manuscripts who are able to supply a Turkish abstract are encouraged to do so.

·         English manuscripts may use British or American spelling, applied consistently. Authors who are not native speakers are strongly advised to have the text professionally edited before submission; manuscripts whose language impedes review may be returned without evaluation.

3.3 Manuscript preparation

·         Use the ADENJ manuscript template (.docx) available here. LaTeX submissions are accepted; submit the PDF for review and the source files upon acceptance.

·         A4 page, 2.5 cm margins, single column for review, Times New Roman 11 pt, 1.5 line spacing, continuous line numbers and page numbers.

·         Section headings numbered decimally (1., 1.1., 1.1.1.); maximum three levels.

Required structure

1.      Title page (separate file, not anonymised) — full title; all authors’ names, affiliations, ORCID iDs, and e-mail addresses; corresponding author’s postal address and telephone; acknowledgements; all declarations listed in §3.7.

2.      Main document (fully anonymised) — title; abstract; keywords; main text; nomenclature; declarations placeholder; references; appendices.

3.      Abstract — 150–250 words, unstructured, self-contained, no citations, no undefined abbreviations. It must state the problem, the method, the principal quantitative results, and the conclusion.

4.      Keywords — 4–6 terms, separated by semicolons, not repeating words in the title where avoidable.

5.      Main text — normally: Introduction (with an explicit statement of novelty and contribution at the end of the section); Materials and Methods / Theory; Results; Discussion; Conclusions. Technical notes and case studies may deviate where justified.

6.      Nomenclature — a symbol list is required for any manuscript using more than ten symbols; Latin symbols, Greek symbols, subscripts, superscripts, and abbreviations in separate groups.

3.4 Units, equations, figures and tables

·         SI units are mandatory. Non-SI units may appear in parentheses where operationally conventional (e.g. flight level, knots).

·         Equations are typed with a formula editor (not images), numbered consecutively in parentheses at the right margin, and referred to as “Eq. (1)”.

·         Figures: minimum 300 dpi for photographs, vector format (.pdf, .eps, .svg) preferred for plots; legible when reduced to a single column width; captions below the figure.

·         Tables: editable text, no images of tables; captions above the table; footnotes marked a, b, c.

·         All figures and tables must be cited in the text in order and must be referred to by number, never as “the figure above”.

·         Reproduced material requires written permission from the copyright holder, supplied at submission, and the source must be cited in the caption.

3.5 References

·         ADENJ uses a numbered (IEEE-style) citation system. Sources are numbered in order of first appearance and cited as [1], [2]–[4].

·         The reference list is ordered by citation number, not alphabetically.

·         DOIs must be supplied for every source that has one. References without DOIs must include a complete, verifiable citation.

·         Unpublished and non-retrievable sources (personal communications, internal reports without a public identifier) should be cited in the text or a footnote, not in the reference list.

·         Excessive self-citation and citations that do not support the accompanying statement will be queried by the editors and may be required to be removed.

3.6 Similarity screening

Every submission is screened with iThenticate. The overall similarity index, excluding the reference list and quotations, must be below 20 %, with no single source exceeding 5 %. Manuscripts above these thresholds are returned or rejected without review. Text recycled from the authors’ own earlier publications is treated as plagiarism unless properly quoted and cited.

3.7 Mandatory declarations

The following statements are required on the title page and are reproduced in the published article. A submission lacking any of them is returned as incomplete.

·         Author Contributions — using the CRediT taxonomy (conceptualisation, methodology, software, validation, formal analysis, investigation, resources, data curation, writing – original draft, writing – review and editing, visualisation, supervision, project administration, funding acquisition).

·         Conflict of Interest — all financial, institutional, and personal relationships that could be perceived as influencing the work, including defence-industry employment, consultancy, and shareholdings; or an explicit statement that none exist.

·         Funding — funder name, programme, and grant number; or a statement that no external funding was received.

·         Ethics Committee Approval — for any study collecting data from human participants (survey, interview, focus group, observation, experiment) or using animals: the name of the committee, the approval date, and the decision number, stated both in the Methods section and on the title page. Studies not requiring approval must say so and give the reason.

·         Data Availability — where the data supporting the findings can be obtained, or the legal, contractual, or security reason why they cannot be shared.

·         Use of Artificial Intelligence — any use of generative AI or AI-assisted tools in the preparation of the manuscript, with the tool, version, and purpose specified. AI tools cannot be listed as authors.

·         Classified and Export-Controlled Content — a statement that the manuscript contains no classified, restricted, or export-controlled information and that the authors have obtained any institutional release approval required (see the Ethical Principles and Publication Policy).

3.8 After submission

·         Manuscripts are first checked by the editorial office for scope, completeness, formatting, and similarity. This pre-check normally takes up to 10 days.

·         Manuscripts passing the pre-check are assigned to a Section Editor and sent to at least two independent external reviewers under double-blind review. A first decision is normally returned within [8] weeks.

·         Revisions must be returned within 30 days (minor) or 60 days (major), accompanied by a point-by-point response letter and a version with changes marked. Later resubmissions may be treated as new submissions.

·         Accepted manuscripts are copy-edited and typeset; authors receive proofs and must return corrections within 5 days. Only typographical corrections are possible at proof stage.

·         Accepted articles are published online as soon as they are ready (“online first”) and are then assigned to the next issue.

3.9 Copyright, licence and fees

·         Authors retain the copyright of their work.

·         Articles are published under the Creative Commons Attribution 4.0 International (CC BY-NC-ND 4.0) licence, permitting reuse with proper attribution.

·         Authors must sign and upload the Copyright and Licence Agreement Form at submission.

·         ADENJ charges no submission, processing, publication, page, or colour fees, and access is free for all readers.
