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,
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 author names rearranged and (b) written confirmation (e-mail, fax,
letter) from all authors that they 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
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.
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 as noted above and result in a corrigendum.
Copyright
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement'
(for more information on this and 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 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 and credit the source(s) in the article. 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 then 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.
Language and language services
Please write your text in good English (American or British usage is accepted,
but not a mixture of these). 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.
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, these 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 removing the need for
a paper trail.
Referees
Please submit, with the manuscript, the names,
addresses and e-mail addresses of three potential referees. Note that the editor retains the sole right to decide whether or not the
suggested reviewers are used.
Use of wordprocessing software
It is important that the file be saved in the native format of the wordprocessor
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 on processing the article. In particular, do not use the wordprocessor'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. 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.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check'
functions of your wordprocessor.
LaTeX
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
see
http://www.elsevier.com/wps/find/authorsview.authors/latex-ees-supported.
The Elsevier 'elsarticle' LaTeX style
file package (including detailed instructions for LaTeX preparation) can be obtained from the Quickguide:
http://www.elsevier.com/latex.
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
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, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also
for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. 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.
Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which
may stand alone or form a subsection of a Discussion or Results and Discussion section.
Vitae
Include in the manuscript a short (maximum 100 words) biography of each author.
Essential title page information
•
Title.
Concise and informative. Titles are often
used in information-retrieval systems. Avoid abbreviations and formulae 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 lower-case 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 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.
•
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.
Abstract
A concise and factual
abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An
abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided,
but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential
they must be defined at their first mention in the abstract itself.
Graphical abstract
A Graphical abstract is optional and should summarize the contents of the article in a concise, pictorial form designed to capture
the attention of a wide readership online. Authors must provide images that clearly represent the work described in the article. 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 × 1328 pixels (h × w) or proportionally more. The image should be readable at a size of 5 × 13 cm using a regular
screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. See
http://www.elsevier.com/graphicalabstracts
for examples.
Authors can make use of Elsevier's Illustration and Enhancement service to ensure the best presentation of their images
also in accordance with all technical requirements:
Illustration
Service.
Highlights
Highlights are mandatory for this journal.
They consist of a short collection of bullet points that convey the core findings of the article and should be submitted in a separate
file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters,
including spaces, per bullet point). See
http://www.elsevier.com/highlights for examples.
Abbreviations
Define abbreviations that are not standard in this field in a footnote to be placed on the
first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well
as in the footnote. Ensure consistency of abbreviations throughout the article.
Acknowledgements
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, 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 the article, etc.).
Nomenclature
and units
Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities
are mentioned, give their equivalent in SI. You are urged to consult IUPAC: Nomenclature of Organic Chemistry:
http://www.iupac.org/
for further information.
Math formulae
Present simple formulae in the
line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle,
variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations
that have to be displayed separately from the text (if referred to explicitly in the text).
Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic
numbers. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position
of footnotes in the text and present the footnotes themselves 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
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.
• 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 finalised, 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 (Word, PowerPoint, Excel)
then please supply 'as is'.
Please do not:
• Supply files that are optimised 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, EPS 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.
For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article.
Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork,
please see
http://www.elsevier.com/artworkinstructions.
Please note: Because of technical complications which can arise
by converting color figures to 'gray scale' (for the printed version should you not opt for color in print) please submit in addition
usable black and white versions of all the color illustrations.
Figure captions
Ensure that each illustration has a caption. Supply captions separately, 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.
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
Please ensure that every reference cited in the text is also 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 as 'in press' implies that the item has been accepted for publication.
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 can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in
the reference list.
Reference style
Text: Indicate references
by number(s) in square brackets in line 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.

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.
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:

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):
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.
Proofs
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. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe
Reader version 7 (or higher) available free from
http://get.adobe.com/reader. Instructions on how to annotate PDF files
will accompany the proofs (also given online). The exact system requirements are given at the Adobe site:
http://www.adobe.com/products/reader/tech-specs.html.
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 return by fax, or scan the
pages and e-mail, or by post. 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 – please let us have all 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 PDF file of the article via e-mail. For an extra
charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. 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 homepage. Contact details for questions arising
after acceptance of an article, especially those relating to proofs, will be provided by the publisher. You can track accepted articles
