Ethics in Publishing

For information on Ethics in publishing and Ethical guidelines for journal publication see and

Animal experiments
Does your research involve experimentation on animals? If so, please provide name of the ethical committee approving these experiments and confirm authors' compliance with all relevant ethical regulations.

Human subjects
Does your study include human subjects? If so, please provide name of the ethical committee approving these experiments, confirm authors' compliance with all relevant ethical regulations, and confirm that written consent has been obtained from all patients.

Informed Consent
If your manuscript related to clinical study, please provide following pieces of information and state them in your manuscript: 1) date of IRB approval and the approval number, 2) status of informed consent (IC); [e.g. Was written IC required? Was your clinical study approved without IC? If so, the reason why?]

I confirm that I have obtained all consents required by applicable law for the publication of any personal details or images of patients, research subjects or other individuals that are used in the materials submitted to Elsevier. I have retained a written copy of all such consents and I agree to provide Elsevier with copies of the consents or evidence that such consents have been obtained if requested by Elsevier.

Clinical research must include IRB approval and patient consent forms.

Declaration of Competing Interest

All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. More information.

Role of the Funding Source

You are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the paper for publication. If the funding source(s) had no such involvement then this should be stated.

Submission Declaration

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see Multiple, redundant or concurrent publication section of our ethics policy for more information), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection service CrossCheck.

Use of Inclusive Language

Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Content should make no assumptions about the beliefs or commitments of any reader; contain nothing which might imply that one individual is superior to another on the grounds of age, gender, race, ethnicity, culture, sexual orientation, disability or health condition; and use inclusive language throughout. Authors should ensure that writing is free from bias, stereotypes, slang, reference to dominant culture and/or cultural assumptions. We advise to seek gender neutrality by using plural nouns ("clinicians, patients/clients") as default/wherever possible to avoid using "he, she," or "he/she." We recommend avoiding the use of descriptors that refer to personal attributes such as age, gender, race, ethnicity, culture, sexual orientation, disability or health condition unless they are relevant and valid. These guidelines are meant as a point of reference to help identify appropriate language but are by no means exhaustive or definitive.

Review of manuscripts
Upon submission to Animal Nutrition, a manuscript is assigned to an editor, who enlists reviewers to assist in the evaluation of the manuscript. The review process is confidential, which infers a bond of trust among the authors, editor, and reviewers. The editor is trustee of the manuscript until the review process is completed and ensures that the review process is fair, thorough, and confidential. Reviewers are asked not to share the contents of the manuscript with anyone, except that they may ask a colleague to assist with the review with approval of the editor. Communication with authors should only be through the editor. Reviewers should notify the editor of conflicts of interest that may compromise their ability to provide a fair and unbiased review. Moreover, they must recognize their responsibility in maintaining the confidential nature of the review. Authors should suggest names of appropriate reviewers when submitting the manuscript to streamline the review process and may list reviewers whom they consider unacceptable because of potential bias. These recommendations will be considered by the editor when assigning reviewers. Authors will generally be notified of acceptance, rejection, or need for revision within 2 months of receipt.

The acceptance of a paper implies that it has been reviewed and recommended by at least two peer reviewers. The Editor-in-Chief's decision is final.

Rejected manuscripts
If a manuscript is rejected, the corresponding author may discuss the matter with the section or senior editor assigned to the manuscript. If the author believes a rejection decision was erroneous or biased, he/she may appeal the decision directly, in writing, to the editor-in-chief. The editor-in-chief will review the author's reasons, as well as all materials related to the manuscript, and will accept or deny the appeal. A rejected manuscript may be resubmitted for publication only if this course of action has been specifically recommended by the Editor-in-Chief.

Time limit of manuscript revision
A reviewed paper returned to authors for revision must be returned to the editor within 6 wk. If not, the paper may be treated as a new submission. Under unusual circumstances, editors may extend the revision deadline beyond 6 wk.
If authors do not revise manuscripts and resubmit over 3 months from the date on which they are invited to revise, and has not obtained the delay of modification by the Editorial Office (subject to the major revision of the trial, agree to postpone the revision), they are deemed to have abandoned the amendment and the manuscript is treated as withdrawn.


Animal Nutrition recommends that authorship be based on the following 4 criteria:

  1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  2. Drafting the work or revising it critically for important intellectual content; AND
  3. Final approval of the version to be published; AND
  4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
To satisfy the requirement for authorship, each contributor must meet all four criteria above. Contributors meeting fewer than the four criteria listed here should be listed in the Acknowledgments section of an article.

More details and an example

Changes to Authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission.

Before the manuscript has been accepted: Requests to add or remove an author, or to rearrange the author names, must be stated in the cover letter by the corresponding author and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) authors agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded to the corresponding author, who must follow the procedure as described above. Note that: processing of the manuscript is suspended until authorship has been agreed.
After the manuscript has been accepted: authorship generally cannot be changed after a manuscript has been accepted. Only in exceptional circumstances will the request for the addition, deletion or rearrangement of authors be considered.


Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.

Poorly written and/or presented manuscripts may be returned to authors for upgrading by Editorial Office, prior to a review for scientific merit.

Use of word processing software

Please prepare manuscripts in Microsoft Word (.doc or .docx format). It is important that the file be saved in the native format of the word processor used. The text should be in single-column format, aligned to the left, typed double-spaced, with all lines and pages numbered consecutively, using Times New Roman font at 12 points. Tables should be typed single-spaced at 12 or smaller points. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier). Note that source files of figures, tables and text graphics will be required. See also the section on Electronic artwork.
To avoid unnecessary errors, you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.


If the LaTeX file is suitable, proofs will be produced without rekeying the text. The article should preferably be written using Elsevier's document class 'elsarticle', or alternatively any of the other recognized classes and formats supported in Elsevier's electronic submissions system, for further information visit our Support Center.
The Elsevier 'elsarticle' LaTeX style file package (including detailed instructions for LaTeX preparation) can be obtained from the Quickguide: It consists of the file: elsarticle.cls, complete user documentation for the class file, bibliographic style files in various styles, and template files for a quick start.

Article Structure

Manuscripts should be organized in the following order:

  • Title page
  • Abstract and keywords
  • Introduction
  • Materials and methods
  • Results
  • Discussion
  • Conclusions
  • Acknowledgements (optional)
  • References
  • Figures
  • Tables
  • Appendix (optional)

Title Page

Title: Concise (preferably 10 to 20 words) and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible. Only widely accepted and well-established abbreviations can appear in the title. Avoid using the word "effect" in the title where possible. If there is a (treatment) effect and it is of significance, this information should be made clear in the title.
Author names and affiliations: Under the title, names of authors should be typed (first name, middle initial, last name). Ensure all names are spelled accurately. If a family name includes more than one word, please underline the family name. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter after the author's name and in front of the appropriate address. Provide the full post address of each affiliation, including 1) affiliated institution, 2) city, 3) country. If available, provide the e-mail address of each author.
Corresponding author: Please use an asterisk (*) to indicate the corresponding author, who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author. If there is more than one corresponding author, use "(author's name)" and a comma to separate the corresponding authors' e-mail addresses. Maximum 2 corresponding authors.
Present/permanent address: If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
• Maximum 3 authors who contributed equally to the work.


The Abstract disseminates scientific information through abstracting journals and through convenience for the readers. The Abstract, consisting of no more than 350 words (around one double-spaced page), is a single paragraph. Go for shorter rather than longer. The ideal length is 250 words for Animal Nutrition. It usually begins with a clear statement of the objective, briefly states the principal methods including trial information such as number of animals and number of replicates, states main findings or results with statistical evidence, i.e., P-value, and ends with main implications or conclusions with no references cited. It must be able to stand alone. Use complete sentences and standard terms. Avoid the use of references, math formulae, symbols, tables or figures.

Graphical Abstract

Although a graphical abstract is optional, its use is encouraged as it draws more attention to the online article. The graphical abstract should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership. Graphical abstracts should be submitted as a separate file in the online submission system. Image size: Please provide an image with a minimum of 531 pixels × 1328 pixels (h × w) or proportionally more. The image should be readable at a size of 5 cm × 13 cm using a regular screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. You can view Example Graphical Abstracts on our information site. Authors can make use of Elsevier's Illustration Services to ensure the best presentation of their images and to confirm that their submitted images are presented in accordance with all technical requirements.


The Abstract is followed by 2 to 6 keywords or phrases to be used for subject indexing. These should include important words from the title and should be singular, not plural, terms (e.g., “pig” not “pigs”). Avoid multiple concepts (e.g., “and”, “of”). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. Keywords should be capitalized and separated by colons (e.g., Feed efficiency; Greenhouse gas emission; Methanogenesis; Tannin Ruminant).


The Introduction states the objectives of the work and provide an adequate background. It contains a brief justification for conducting the research, the hypotheses to be tested, and the objective(s). Extensive discussion of relevant literature should be included in Discussion, not in Introduction.

Materials and Methods

The institutional animal care and use committee statement should appear as the first item in the section of materials and methods in manuscripts, and authors should specify which publicly available animal care and use standards were followed.

This section must contain a clear description of how the experiment was conducted and how the data were analyzed. It should provide sufficient detail to allow the work to be reproduced. Diets, periods of experimental activities if appropriate, animals (breed, sex, age, body weight, and weighing conditions), surgical techniques, measurements, additives (do not just give product names or trademark names), and statistical models should be described clearly and fully.

Manufacturer information must be provided at the first mention of each proprietary product used in the research. The generic term for all drugs and chemicals should be used, unless the specific trade name of a drug is directly relevant to the discussion. Methods already published should be indicated by a reference: only relevant modifications should be described.


Results should be clear and concise, which explain or elaborate on data presented in the tables. Sufficient data, all with some index of variation attached, including significance level (i.e., P-value) should be presented to allow readers to interpret the results of the experiment.

One of the hallmarks for experimental evidence is repeatability. Care should be taken to ensure that experiments are adequately replicated. The results of experiments must be replicated, either by replicating treatments within experiments or by repeating experiments.

The terms significant and highly significant traditionally have been reserved for P < 0.05 and P < 0.01, respectively. When available, the observed significance level (e.g., P = 0.027) should be presented rather than merely P < 0.05 or P < 0.01. Do not report P-values to more than 3 places after the decimal.


Discussion should explore the significance of the results of the work. Discussion integrates the research findings with the body of previously published literature to provide the reader with a broad base on which to accept or reject the hypotheses tested. Avoid extensive citations and discussion of published literature.

Results and discussion may be combined into a single section. If not, the Results section should not contain discussion of previously published work. Results and references to tables and figures already described in the Results section should not be repeated in the Discussion section.


The main finding or conclusions of the study may be summarized in a brief paragraph, which may stand alone or form a subsection of Discussion.

Authors may submit a short (maximum 100 words) biography of each author, along with a passport-type photograph accompanying the other figures, in an editable format (e.g. Word).


An Acknowledgments section, if desired, should follow the Conflict of Interest section. List sources of financial support with grant numbers, experiment station, and those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.) in a succinct and appropriate manner but not as a long list of tributes and accolades.


All publications cited in the text should be presented in a list of references following the text of the manuscript. The manuscript should be carefully checked to ensure that the spelling of authors' names and dates are exactly the same in the text as in the reference list. The accuracy of the references is the responsibility of the author(s).

References published in other than the English language should be avoided, but are acceptable if they include an English language 'Abstract' and the number of non-English language references cited are reasonable (in the view of the handling Editor) relative to the total number of references cited.

Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Unpublished results and personal communications are not permitted in the reference list, but may be mentioned in the text.

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references are included in the reference list, not listed separately.

References in a Special Issue
Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

Citations in text

All citations in the text should refer to:

  1. Single author: the author's name (without initials, unless there is ambiguity) and the year of publication;
  2. Two authors: both authors' names and the year of publication;
  3. Three or more authors: first author's name followed by 'et al.' and the year of publication.
Citations may be made directly or parenthetically. Groups of references should be listed first alphabetically, then chronologically.
Examples: 'as demonstrated (Allan, 1996a, 1996b, 1999; Allan and Jones, 1995). Kramer et al. (2000) have recently shown ...'

Reference list

References should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters 'a', 'b', 'c', etc., placed after the year of publication.

Animal Nutrition is a fully electronic publication. Authors are encouraged to use color to enhance figures. However, please only use color when absolutely necessary because many people are color blind. Number figures according to their sequence in the text. Keep text in the figures themselves to a minimum. Provide sufficient information in captions so that figures can be understood without excessive reference to the text.

Figure captions
Figure captions should comprise a brief title (not on the figure itself), a description of the figure, and abbreviation definitions. Place figure captions beneath figures.
It is permissible to use an abbreviation for the axis description as long as it is a common abbreviation or identified in the caption. Units of measures, when needed, follow the axis description, separated by a comma.

Electronic artwork

General points
• Make sure you use uniform lettering and sizing of your original artwork.
• Save text in illustrations as “graphics” or enclose the font.
• Only use the following fonts in your illustrations: Arial, Courier, Times, Symbol.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Produce images near to the desired size of the printed version.
A detailed guide on electronic artwork is available.
You are urged to visit this site; some excerpts from the detailed information are given here.
Regardless of the application used, when your electronic artwork is finalized, please “save as” or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save the text as “graphics”
TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1,000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is'.
Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Color Artwork

Please make sure that artwork files are in an acceptable format (TIFF or JPEG, EPS or PDF, or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version.


Please submit tables as editable text and not as images. Number tables consecutively in accordance with their appearance in the text. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Limit the data field to the minimum needed for meaningful comparison within the accuracy of the methods. For example, results should not be presented to 5 digits when the instrument used only reads to 2 digits. Specify the basis (i.e., as-is, as-fed or dry matter basis) for dietary ingredient and chemical composition data listed in text or in tables. Similarly, specify the basis for tissue composition data (e.g., wet or dry basis). Papers with several tables must use consistent format. Abbreviations must match those used in the text. Units of measure for each variable must be indicated. Commas should be used to separate items or headings from the units of measure. Footnotes to tables must be marked by superscript numbers, and superscript letters should be used for statistical comparisons. Each footnote begins a new line.


A technical appendix, if desired, shall follow the Tables section. The appendix may contain supplementary material, explanations, and elaborations that are not essential to other major sections but are helpful to the reader. Tables and figures are formatted as follows: Appendix Table 1, Appendix Table 2. Appendix Fig. 1 and so on.


For an unabbreviated term that is long or complex, use of an abbreviation may be helpful. Where such a term is continually referred to, it must be written in full when it first appears in the abstract, in text and in tables and figures, followed by the subsequent abbreviation in parentheses; thereafter, the abbreviation may always be used. Widely accepted and well–established abbreviations are allowed to appear without definition. However, the intended meaning must be unambiguous from the context.

Excessive use of abbreviations can confuse the reader. If an abbreviation is not needed more than 3 times in the following text, it should not be used; the term it represents should be spell out, or the text in which it appears should be rewritten to eliminate the need for the abbreviation.

  • The abstract, text, each table, and each figure must be understood independently of each other. Therefore, abbreviations should be defined within each of these units of the manuscript.
  • Abbreviations should not be used in the title, key words, or to begin sentences, except when they are widely known and well-established throughout science (e.g., DNA, RNA) or are terms better known by their abbreviation (e.g., IgG).
  • Chemical symbols and three-letter abbreviations for amino acids do not need definition (e.g., Na, Pa, Ala, Cys).
  • Do not use single-letter abbreviations that could be confused with chemical elements (e.g., P, C, S).
  • Plural abbreviations do not require "s."
  • Do use abbreviated unit "s", "min", "h", "d", "wk", "mo", "y" rather than full words when it is used after a number, e.g. 2 h, 3 min, 20 s, 5 d.
  • P (probability) is always a capital letter P in italics.
  • Liter or Litre is always a capital letter "L", e.g. mL, dL.
  • "Table" is always capitalized and never abbreviated.
  • "Figure" is abbreviated to "Fig.", except at the beginning of a sentence.
  • Except at the beginning of a sentence, "experiment" and "equation" preceding a numeral is abbreviated to "Exp." and "Eq.", e.g. Exp. 1, Eq. 1.

Miscellaneous Usage Notes

  • Use numerals rather than words to express numbers in text, titles, headings, tables, and figure captions except when they begin a sentence.
  • Use thousand separators in numbers greater than 999 (e.g., 1,200).
  • Insert spaces around all signs (except slant lines) of operation (=, –, +, ±, ×, ≥, >, ≤, or <) when these signs occur between 2 items.
  • Units of measure not preceded by numbers must be written out rather than abbreviated (e.g., provide the following in milligrams per kilogram of diet) unless used parenthetically.
  • The use of names of commercial products should be minimized. Only generic names should be used in article titles.
  • Registered (®) and trademark (©, ™) symbols should not be used, unless as part of an article title in the References section. Trademarked product names should be capitalized.
  • Non-English words in common usage will not appear in italics (e.g., in vitro, in vivo, ad libitum, in situ, a priori, i.e., et al., etc.).
  • Avoid jargon unfamiliar to scientists from other disciplines. Do not use the term "head" to refer to an animal or group of animals. Instead, use "animal, sow, ewe, steer, heifer, cattle", etc.
  • Restrict the use of "while" and "since" to meanings related to time. Appropriate substitutes include "and ", "but" or "whereas" for "while" and "because" "even though" or "although" for "since".

Units of Measure

Follow internationally accepted rules and conventions: use the international system of units (SI)and SI derived units that are widely used in conjunction with SI units. The following site (National Institute of Standards and Technology) provides a comprehensive guide to SI units and usage:

Centrifugal force

Centrifugal force should be provided in × g with the duration, temperature, and type of centrifugation, e.g. "centrifuged at 3,000 × g at 4 °C for 15 min". Centrifugation expression using "rpm" or "r/min" should be converted to centrifugal force, because g force depends on radius of the rotor and the speed of revolution. The following website gives a list of conversions:


Current standard international nomenclature for genes should be adhered to. Authors are required to use only approved gene and protein names and symbols. In general, full gene names should not be italicized and gene symbols should be in italics. A protein symbol should be in the same format as its gene except the protein symbol should not be in italics. For human genes, use genetic notation and symbols approved by the HUGO Gene Nomenclature Committee ( or refer to PubMed ( entrez). The Human Genome Variation Society also has a useful site that provides guidance in naming mutations at

Math Formulae

Please submit math equations as editable text and not as images.
Present simple formulae in the line of text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y.
Display complex formulae separately from the text, and use MathType to enter complex formulae. If they are referred to explicitly in the text, number them consecutively.

Research Data

This journal encourages and enables you to share data that supports your research publication where appropriate, and enables you to interlink the data with your published articles. Research data refers to the results of observations or experimentation that validate research findings. To facilitate reproducibility and data reuse, this journal also encourages you to share your software, code, models, algorithms, protocols, methods and other useful materials related to the project.

Below are a number of ways in which you can associate data with your article or make a statement about the availability of your data when submitting your manuscript. If you are sharing data in one of these ways, you are encouraged to cite the data in your manuscript and reference list. Please refer to the "References" section for more information about data citation. For more information on depositing, sharing and using research data and other relevant research materials, visit the research data page.

Data Linking

If you have made your research data available in a data repository, you can link your article directly to the dataset. Elsevier collaborates with a number of repositories to link articles on ScienceDirect with relevant repositories, giving readers access to underlying data that give them a better understanding of the research described.

There are different ways to link your datasets to your article. When available, you can directly link your dataset to your article by providing the relevant information in the submission system. For more information, visit the database linking page.

For supported data repositories a repository banner will automatically appear next to your published article on ScienceDirect.

In addition, you can link to relevant data or entities through identifiers within the text of your manuscript, using the following format: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).

Mendeley Data

This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols, and methods) associated with your manuscript in a free-to-use, open access repository. During the submission process, after uploading your manuscript, you will have the opportunity to upload your relevant datasets directly to Mendeley Data. The datasets will be listed and directly accessible to readers next to your published article online.

For more information, visit the Mendeley Data for journals page.

Data statement

To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.


Use of the Digital Object Identifier

The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal Physics Letters B):

When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.


One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or a link will be provided in the e-mail so that authors can download the files themselves. To ensure a fast publication process of the article, we kindly ask authors to provide us with their proof corrections within two days. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download the free Adobe Reader, version 9 (or higher). Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and scan the pages and return via e-mail. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.
