References

All articles submitted for publication in Comptes Rendus Mécanique must be supported by reliable scientific sources. Manuscripts without bibliographical references will be rejected without evaluation.

In the body of the text

The sources underlying your article must all be mentioned in the body of your article, regardless of :

• when they were written or published ;
• their target audience (general public, amateurs, professionals, scientific community, etc.) ;
• their type (web page, journal article, book, conference proceedings, encyclopedia entry, dataset, image, source code, manuscript, archive document, etc.);
• their publication status (preprint, published article, etc.):
  • if the cited document has not yet been accepted for publication, please cite the publicly available preprint,
  • if the cited document has several versions (e.g. arXiv manuscripts, datasets, etc.), please specify which version you consulted at the time of writing,
  • if your article is intended for inclusion in a special issue of Comptes Rendus, please wait until all your bibliographical references have been accepted for publication before citing them;
• the language in which they were written.

Please also mention the exact source of figures and illustrations (if not originals). For any photograph or image reproduction, please mention the original archive or publication, in addition to the source of the image itself.

Instructions for presenting references in the body of the text:

• Enter the number of your reference in right square brackets, listing them sequentially as they appear in the text (autotext, fields, bookmarks, captions, cross-references, etc.);
• If you wish to cite several references at the same time, assign a number to each, and separate them with a semicolon. E.g.: [25; 26];
• If necessary, specify the exact pagination of the passage/figure you are referring to, bearing in mind that the overall pagination of the journal article or book chapter cited will appear in the final bibliography. E.g.: [42, p. 283];
• If you wish to add a bibliographical comment to your reference, present it in the form of a footnote or endnote.

Final bibliography

All your article's primary and secondary sources must be included in a single final bibliography (not organized into subsets).

Your bibliography should be limited to the references mentioned throughout the text: any additional comments may appear in your manuscript as footnotes or endnotes, but not in the bibliography itself.

Instructions for presenting references in the final bibliography :

• Arrange your references in alphabetical order of the first author's surname, then in chronological order;
• Be sure to provide as much bibliographical information as possible: authors, title of article, title and number of journal, date of publication, pagination, publisher and city of publication for books, etc...;
• If you can, include the precise identifiers (DOI, handle, ARK...) of the documents cited, as well as their URLs;
• Don't worry about formatting (bold, italics, etc.): formatting will be done when you prepare the proofs;
• Ensure that all references cited in the text (including in the captions of illustrations, graphs and tables) are included in the bibliography.

If you use bibliographic management software such as Zotero, feel free to submit your bibliography in .bib or .ris format at the same time as your article. If your article is written with TeX, submitting your .bib file is mandatory.

NB: Your bibliographic references will be reformatted by our editorial teams, so the examples above are not identical to the references you might find in our already published articles.

Math formulæ

Please:

• Submit mathematical equations as editable text, not images, and number them;
• Submit simple formulas, in-line, with normal text whenever possible;
• Use solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y;
• Place exponents and subscripts carefully - so write x₁ and not x1;
• Avoid ambiguous expressions such as 1/2x - so write either 1/(2x), or (1/2)x;
• Make sure that a given quantity is always designated by the same symbol in the same typeface - for example, a length L (written in italics) will not be called L elsewhere;
• Italicize mathematical or physical quantities, such as the x-axis or a m mass - thus distinguishing x+1 from x+l, and the logarithm ln from the product of l by n ;
• Indicate the powers of e by exp.;
• No sentence should begin with a mathematical formula
• Each numbered formula must be cited in the text by its number.

Illustrations

Please:

• Integrate your illustrations directly into your text and PDF files, in the best possible resolution;
• Label all your illustrations as figures and/or diagrams;
• Number your illustrations in Arabic numerals, in the order they appear in the article;
• Use consistent units and symbols between all illustrations and with the text;
• Use consistent lettering and dimensions for all original illustrations;
• Use Helvetica as the preferred font (if not available, use Arial, Courier, Times New Roman, Symbol or similar fonts) for text appearing in figures;
• Check that your illustrations will be adapted to a resizing on 75 mm width (single column), 160 mm for illustrations straddling two columns;
• Make sure that none of your illustrations exceed A4 size (210 x 297 mm);
• Ensure that photographs and halftones have good contrast;
• Make sure that the characters integrated in your illustrations remain legible even after reducing the size of the illustrations by 70%;
• Integrate the fonts used directly into your illustrations if the design software you use allows it;
• Provide a caption for each of your illustrations;
• Specify the exact source of your illustrations if they are not original works (citing the original work and any secondary works in which you have consulted reproductions, if necessary);
• Check that your illustrations are all cited in the body of the text.

Please use only royalty-free illustrations in your manuscript. Please use only royalty-free illustrations in your manuscript. If you wish to re-use an illustration protected by copyright (which may be the case for all images found on the internet using a search engine), please find out who the copyright holders are and obtain written authorisation to re-use it under a Creative Commons CC BY 4.0 license (see below).

If you also provide illustrations as separate files, please send them in the best possible resolution and choose image formats (JPEG, PNG, EPS, ChemDraw, Adobe Illustrator... - note that EPS format is not suitable for images containing text). When enlarged to 400%, your illustrations should not become blurred or pixelated.

Tables

Please:

• Use only one grid for each individual table, not one grid for each row;
• Align columns using tabs (not spaces) if your table does not have a grid;
• Number your tables in Roman numerals, in the order they appear in the article;
• Avoid vertical lines within tables;
• Accompany each table with a caption;
• Group all your tables at the end of the manuscript, even if they appear in the text.

Conventions and abbreviations

Abbreviations should be defined in brackets the first time they are used in the text, with the exception of standard abbreviations. Units, symbols and nomenclature should follow international conventions (International System, IS). Standard units of measure and chemical symbols do not need to be defined in the text (the format m/s or m.s–1 are both acceptable, but should not be both used in the same article).

Open data policy

Source files

Authors wishing to publish in Comptes Rendus Mécanique are requested to provide all the files necessary for the formatting of their article in the most interoperable formats possible, in order to facilitate the work of the editors.

In order to encourage the free circulation of scientific knowledge, authors are strongly encouraged to accept the publication by Comptes Rendus Mécanique of these source files, together with the editorialized files. The dissemination of figures, in particular, especially when made available in an interoperable format and in high quality resolution, is a strong commitment to more open and robust science.

Underlying Data

Research data includes all "materials in digital form, other than scientific publications, that are collected or produced in the course of scientific research activities and used as evidence in the research process, or that are commonly accepted by the scientific community as necessary to validate research findings and results" (source: EU Directive 2019/1024).

Authors wishing to publish in the Comptes Rendus Mécanique are encouraged to make all data related to the research work they describe in their manuscripts, and in particular the data directly underlying the submitted articles, freely available.

To do so, Comptes Rendus Mécanique strongly recommends that authors deposit their data in warehouses, i.e. databases specifically dedicated to the permanent preservation, enrichment and valorization of the materials they host. Datasets deposited in repositories are scientific productions that can be cited (in particular when they have a permanent identifier such as DOI), in the same way as a traditional publication.

It is recommended that authors release their data without embargo or after the shortest possible delay, in a way that allows their reuse, with an explicit link between the data and the underlying publication (reciprocal mention of the DOI). The journal encourages the provision of data under open licenses that allow their free reuse. Authors must use the licenses recommended by the repository where the data were deposited.

Reviewers of submitted articles may at any time request from authors the data underlying the results described. Failure to provide this data will result in the rejection of the submission.

NB: Research data should be as open as possible, but as closed as necessary. The Academy of Sciences and the editorial team of Comptes Rendus Mécanique cannot be held responsible for any failure to respect the rights associated with the exploitation or dissemination of the data underlying the articles published by the journal. Authors are invited to inquire about any intellectual or industrial property issues that may arise with their data.

Data Repositories

To select a trusted repository appropriate for your data type or disciplinary area, consult the re3data directory. Check that the chosen repository meets quality criteria.

We should also mention Zenodo, a multidisciplinary data warehouse, supported by CERN and the European Commission. The data deposit is not moderated.

Supplementary material

Authors who wish to publish in the Comptes Rendus Mécanique may attach to the full text of their submission additional files or material, independent of the body of the article but essential to its understanding. As this material is subject to the peer review process, it must be included and clearly marked as "Supporting Information for Electronic Publication" when the article is submitted. To ensure that your material is directly usable, please make sure that each file does not exceed 50 MB.

However, for reasons of technical constraints, valuation, preservation and reuse, authors are strongly advised to deposit this additional material in dedicated repositories, rather than publishing it as an appendix to the articles.
