\section*{Title Page}

{\label{265740}}

\textbf{Title:} Concise and informative. Titles are often used in
information-retrieval systems. Avoid abbreviations and formulae where
possible.

\textbf{Author names and affiliations:} Please clearly indicate the
given name(s) and family name(s) of each author and check that all names
are accurately spelled. 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.

\textbf{Corresponding author:} Clearly indicate who will handle
correspondence at all stages of refereeing and publication, also
post-publication. Ensure that the e-mail address is given and that
contact details are kept up to date by the corresponding author.

\textbf{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.

\section*{Abstract}

{\label{986821}}

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.

\section*{Keywords}

{\label{307856}}

Immediately after the abstract, provide a maximum of 6 keywords, using
American spelling and avoiding general and plural terms and multiple
concepts (avoid, for example, `and', `of'). Be sparing with
abbreviations: only abbreviations firmly established in the field may be
eligible. These keywords will be used for indexing purposes.

\section*{Introduction}

{\label{375419}}

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

\section*{Material and methods}

{\label{349013}}

Provide sufficient detail to allow the work to be reproduced. Methods
already published should be indicated by a reference: only relevant
modifications should be described.

Theory/calculation A Theory section should extend, not repeat, the
background to the article already dealt with in the Introduction and lay
the foundation for further work. In contrast, a Calculation section
represents a practical development from a theoretical basis.

\section*{Results}

{\label{673180}}

Results should be clear and concise. Example citation\hyperref[csl:1]{[1]}

\section*{Discussion}

{\label{222414}}

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

\section*{Conclusions}

{\label{465935}}

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.
