Ethics in publishing

For information on Ethics in publishing and Ethical guidelines for journal publication see http://www.elsevier.com/publishingethics and http://www.elsevier.com/journal-authors/ethics.

Policy and ethics

The work described in your article must have been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans http://www.wma.net/en/30publications/10policies/b3/index.html; EU Directive 2010/63/EU for animal experiments http://ec.europa.eu/environment/chemicals/lab_animals/legislation_en.htm; Uniform Requirements for manuscripts submitted to Biomedical journals http://www.icmje.org. This must be stated at an appropriate point in the article.

Conflict of interest

Authors are required to disclose all financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. See also http://www.elsevier.com/conflictsofinterest.

Submission declaration and verification

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), 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and tacitly or explicitly by the responsible authorities where the work was carried out, and that if accepted it will not be published elsewhere, including publication by electronic methods, in the same form, in English or in any other language, without written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection software iThenticate. See also http://www.elsevier.com/editors/plagdetect.

Authorship

All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting of the article or revising it critically for important intellectual content, (3) final approval of the version being submitted.

Changes to authorship

This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
Before the accepted manuscript is published in an online issue: Requests to add or remove an author's name or to rearrange the author names must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include (a) the reason the name should be added or removed or the reason the author names should be rearranged, and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the event of an addition or a removal of a name, this will include confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed on.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies noted above and result in a corrigendum.

Reporting clinical trials

Randomized controlled trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. The CONSORT checklist and template flow diagram can be found on http://www.consort-statement.org.

Observational studies should be presented according to the STROBE statement. At manuscript submission, authors must provide the STROBE checklist. The STROBE checklists can be found on http://www.strobe-statement.org.

Copyright

Upon acceptance of an article, authors will be asked to complete a "Journal Publishing Agreement" (for more information on this and on the copyright, see http://www.elsevier.com/copyright). Acceptance of the agreement will ensure the widest possible dissemination of information. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a "Journal Publishing Agreement" form or a link to the online version of this agreement.
Subscribers may reproduce tables of contents or prepare lists of articles, including their abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations (please consult http://www.elsevier.com/permissions). If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners of these works and credit the source(s) in the article. As for a commissioned article, please contact Editorial Office. Elsevier has preprinted forms for use by authors in these cases. Please consult http://www.elsevier.com/permissions.

Retained author rights

As an author you (or your employer or institution) retain certain rights; for details you are referred to http://www.elsevier.com/authorsrights.

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 article for publication. If the funding source(s) had no such involvement, this should be stated. Please see http://www.elsevier.com/funding.

Funding body agreements and policies

Elsevier has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier to comply with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements and policies please visit http://www.elsevier.com/fundingbodies.

Green open access

Authors can share their research in a variety of different ways and Elsevier has a number of green open access options available. We recommend authors see our green open access page for further information (http://elsevier.com/greenopenaccess). Authors can also self-archive their manuscripts immediately and enable public access from their institution's repository after an embargo period. This is the version that has been accepted for publication and which typically includes author-incorporated changes suggested during submission, peer review and in editor-author communications. Embargo period: For subscription articles, an appropriate amount of time is needed for journals to deliver value to subscribing customers before an article becomes freely available to the public. This is the embargo period and begins from the publication date of the issue your article appears in.

This journal has an embargo period of 12 months.

Language and language services

Please write your text in good English (consistent American or British usage is accepted, but not a mixture of these languages). Authors who require information about language editing and copyediting services pre and post submission, please visit http://webshop.elsevier.com/languageservices or our customer support site at http://support.elsevier.com for more information.

Patient details

Unless you have written permission from the subject patient (or, where applicable, the next of kin), the personal details and/or personal information of any patient included in any part of the article and in any supplementary materials (including all illustrations and videos) must be removed before submission. For further information, see http://www.elsevier.com/patientphotographs.

Submission

Submission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is used in the peer-review process. Please note that even though manuscript source files are converted to PDF files at submission for the review process, the source files are needed for further processing after acceptance. All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail, thus removing the need for a paper trail.

Submit your article

Please submit your article via http://ees.elsevier.com/jarr/

Use of word processing software

It is important that the file be saved in the native format of the word processor being used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced upon processing of 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, and other font variation when necessary. When preparing tables with a table grid, use only one grid for each individual table and not one for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). Note that source files of figures, tables, and text graphics will be required, whether or not you embed your figures in the text. See also the section on Electronic artwork artwork. To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your word processor.

Article structure

Subdivision-numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, etc.), 1.2, 1.3. etc. (the abstract is not included in section numbering). Use this numbering system also for internal cross-referencing: do not refer only to "the text". Any subsection may be given a brief heading and each heading should appear on its own separate line.

Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Material and methods
Provide sufficient details to allow reproduction the work. Methods already published should be indicated by a reference, and only relevant modifications should be described.

Results
The results should be clear and concise.

Discussion
A discussion should explore the significance of the work's results, not repeat them. A combined results and discussion section is often appropriate. Avoid extensive citations and discussions of published literature.

Conclusions
The main conclusions of the study may be represented in a short, conclusions section, which may stand alone or form a discussion section or a results and discussion section.

Appendixes
If there is more than one appendix, they should be identified as A, B, C, etc. Formulas and equations in appendixes should be given separate numberings: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. The same method should be used for tables and figures: Table A.1; Fig. A.1, etc.

Disclosures
All potential conflicts of interest must be identified in this section. Potential conflicts of interest that should be disclosed include: all financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding.

Essential title page information

Title. Concise and informative. Titles are often used in information retrieval systems. Avoid abbreviations and formulas where possible.
Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lowercase superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and if available, the e-mail address of each author.
Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also postpublication. 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.
Present/permanent address. If an author has moved since the work described in the article was done, or if the author 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.

Abstract

A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the methods, the principal results, and major conclusions. A structured abstract is required for the Original article and the format should consist of the sections, labeled "Background", "Methods", "Results", and "Conclusions". An abstract is often presented separate from the article: thus it must be able to stand alone. For this reason, References should be avoided, but if essential they must be defined at their first mention in the abstract itself. The length should be no more 100 words for a Short report. An abstract is not required for a Letter to editor and an ECG for Student and Associated Professionals, an EPS and related Devices for Resident Physicians and a Basic Science for Clinicians.

Keywords

Immediately after the abstract, provide a maximum of 5 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Use only a few abbreviations, and only abbreviations that are firmly established in the subject field may are allowed. These key words will be used for indexing purposes.

Abbreviations

Define abbreviations that are not standard in the subject field at first mention. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote(s). Ensure the consistency of abbreviations throughout the article.

Acknowledgments

Collate all acknowledgments in a separate section at the end of the article before the references, and therefore do not include them on the title page as a footnote to the title, or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance, or proof-reading, and other important contributors).

Nomenclature and units

Follow internationally accepted rules and conventions, and use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI units. You are urged to consult IUB: Biochemical Nomenclature and Related Documents: http://www.chem.qmw.ac.uk/iubmb/ for further information.

Database linking and Accession numbers

Elsevier aims at connecting online articles with external databases which are useful in their respective research communities. If your article contains relevant unique identifiers or accession numbers (bioinformatics) linking to information on entities (genes, proteins, diseases, etc.) or structures deposited in public databases, then please indicate those entities according to the standard explained below.
Authors should explicitly mention the database abbreviation (as mentioned below) together with the actual database number, bearing in mind that an error in a letter or number can result in a dead link in the online version of the article.
Please use the following format: Database ID: xxxx
Links can be provided in your online article to the following databases (examples of citations are given in parentheses):

GenBankhttp://www.ncbi.nlm.nih.gov/genbank/: Genetic sequence database at the National Center for Biotechnical Information (NCBI) (GenBank ID: BA123456)
PDBhttp://www.rcsb.org/pdb/home/home.do: Worldwide Protein Data Bank (PDB ID: 1TUP)

UniProthttp://www.uniprot.org/: Universal Protein Resource Knowledgebase (UniProt ID: Q9H0H5)

Footnotes

Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many word processors build footnotes into the text, and this feature may be used. Should this not be so, indicate the position of footnotes in the text and present them separately at the end of the article. Do not include footnotes in the Reference list.

Table footnotes
Indicate each footnote in a table with a superscript lowercase letter.

Artwork

Image manipulation
Whilst it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. For graphical images, this journal is applying the following policy: no specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Adjustments of brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Nonlinear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend.

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.
• Use only the following fonts in your illustrations: Arial, Courier, Times, Symbol.
• Number the illustrations according to their sequence in the text.
• Use only logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Produce images near to the desired size of the printed version.
• Submit each figure as a separate file.

A detailed guide on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions
You are urged to visit this site; some excerpts from the detailed information are given here.

Formats
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 1000 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, then please supply "as is"

Please do not:
• Supply files that are optimized for screen use (such a 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, EPS, or MS Office files) and with the correct resolution. If you submit usable color figures together with your accepted article, 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 these illustrations are reproduced in color in the printed version. For further information on the preparation of electronic artwork, see http://www.elsevier.com/artworkinstructions.

Please note: Because of technical complications that can arise by converting color figures to "gray scale" (for the printed version should you not opt for color in print), also submit in addition usable black-and-white versions of all the color illustrations.

Figure captions
Be sure that each illustration has a caption, supplied separately and not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Text graphics
Text graphics may be embedded in the text at the appropriate position. Further, high-resolution graphics files must be provided separately whether or not the graphics are embedded. See further under Electronic artwork.

Tables

Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body, and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables, and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

References

Citation in text
Every reference cited in the text must be present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either "Unpublished results" or "Personal communication". Citation of a reference, such as "in press" implies that the item has been accepted for publication and a copy of the relevant article's title page must be submitted.

Web references
As minimum reference information, the full URL should be given and also the date when it was last accessed. Any further information, if known (such as DOI, author name(s), dates, and reference to a source publication), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or they can be included in the reference list.

Reference style
Text: Indicate references by number(s) in square brackets in accordance with the text. The actual authors can be referred to, but the reference number(s) must always be given.

List: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.

Examples:

Reference to a journal publication:
[1] Van der Geer J, Hanraads JAJ, Lupton RA. The art of writing a scientific article. J Sci Commun 2010;163:51–9.
Reference to a book:

Note shortened form for last page number. e.g., 51–9, and that for more than 3 authors the first 3 should be listed followed by 'et al.' For further details you are referred to 'Uniform Requirements for Manuscripts submitted to Biomedical Journals' (J Am Med Assoc 1997;277:927–34) (see also http://www.nlm.nih.gov/bsd/uniform_requirements.html).

Journal abbreviations source
Journal names should be abbreviated according to
Index Medicus journal abbreviations: http://www.nlm.nih.gov/tsd/serials/lji.html; List of title word abbreviations: http://www.issn.org/2-22661-LTWA-online.php; CAS (Chemical Abstracts Service): http://www.cas.org/sent.html.

Video data

Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

The video data are especially emphasized for the following categories:
• Ablation
• MRI
• CTA echo
• Cardiograph

Supplementary data

Elsevier accepts electronic supplementary material to support and enhance your scientific research. Supplementary files offer the author additional possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier web products, including ScienceDirect: http://www.sciencedirect.com. To ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at http://www.elsevier.com/artworkinstructions.

Submission checklist

The following list will be useful during the final checking of an article prior to sending it to the journal for review. Please consult this Guide for Authors for further details of any item.

Ensure that the following items are present:

One Author has been designated as the corresponding author with contact details:
• E-mail address
• Full postal address
• Telephone and fax numbers
All necessary files have been uploaded, and contain:
• Keywords
• All figure captions
• All tables (including title, description, footnotes)
Further considerations
• Manuscript has been 'spell-checked' and 'grammar-checked'
• References are in the correct format for this journal
• All references mentioned in the Reference list are cited in the text, and vice versa
• Permission has been obtained for the use of copyrighted material from other sources (including the web).

As for a commissioned article, please contact Editorial Office.

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 alphanumeric character string that 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, especially "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):
doi:10.1016/j.physletb.2010.09.059
When you use the DOI to create URL hyperlinks to documents on the web, the DOIs are guaranteed never to change.

Online proof correction

Corresponding authors will receive an e-mail with a link to our ProofCentral system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF. We will do everything possible to get your article published quickly and accurately - please upload all of your corrections within 48 hours. 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. Note that Elsevier may proceed with the publication of your article if no response is received.

Offprints

The corresponding author, at no cost, will be provided with a personalized link providing 50 days free access to the final published version of the article on ScienceDirect. This link can also be used for sharing via email and social networks. For an extra charge, paper offprints can be ordered at http://webshop.elsevier.com. The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use.



For inquiries relating to the submission of articles (including electronic submission) please visit this journal's home page. Contact details for questions arising after acceptance of an article, especially those relating to proofs, will be provided by the publisher. Accepted articles may be tracked at http://www.elsevier.com/trackarticle. You can also check our Author FAQs (http://www.elsevier.com/authorFAQ) and/or contact Customer Support via http://support.elsevier.com.
