 \section{Introduction}
-\hypertarget{introduction}{}
+%\hypertarget{introduction}{}
 
 \file{elsarticle.cls} is a thoroughly re-written document class
 for formatting \LaTeX{} submissions to Elsevier journals.
 The class uses the environments and commands defined in \LaTeX{} kernel
-without change to the signature so that clashes with other
-contributed \LaTeX{} packages like \file{hyperref.sty},
+without any change in the signature so that clashes with other
+contributed \LaTeX{} packages such as \file{hyperref.sty},
 \file{preview-latex.sty}, etc., will be minimal.
 \file{elsarticle.cls} is primarily built upon the default
-\file{article.cls}.  The class depends on the following packages
-for its proper functionality:
-
-\begin{enumerate}[1.]
-
-\item \file{pifont.sty} for openstar in the title footnotes.
-\item \file{natbib.sty} for citation processing.
-\item \file{geometry.sty} for margin settings.
-\item \file{fleqn.clo} for left aligned equations.
-\item \file{graphicx.sty} for graphics inclusion.
-\item \file{txfonts.sty} optional font package, if document is to

-\item \file{hyperref.sty} optional packages if hyper linking is

+\item \file{hyperref.sty} optional packages if hyperlinking is
   required in the document.
 
 \end{enumerate}
 
 All the above packages are part of any standard \LaTeX{} installation.
 Therefore, the users need not be bothered about downloading any
-extra packages.  Further, users are free to make use of \textsc{ams}

-Many Elsevier journals print their text in two columns. Because
-the preprint layout uses a larger line width than such columns,
-the formulas are too wide for the line width in print. Here is an
-example of an equation  (see equation 6) which is perfect in
-single column preprint format:

-Therefore, authors may check their submissions for the incidence

-\section{Introduction}
-\hypertarget{introduction}{}
-
-\file{elsarticle.cls} is a thoroughly re-written document class
-for formatting \LaTeX{} submissions to Elsevier journals.
-The class uses the environments and commands defined in \LaTeX{} kernel
-without change to the signature so that clashes with other
-contributed \LaTeX{} packages like \file{hyperref.sty},
-\file{preview-latex.sty}, etc., will be minimal.
-\file{elsarticle.cls} is primarily built upon the default
-\file{article.cls}.  The class depends on the following packages
-for its proper functionality:
-
-\begin{enumerate}[1.]
-
-\item \file{pifont.sty} for openstar in the title footnotes.
-\item \file{natbib.sty} for citation processing.
-\item \file{geometry.sty} for margin settings.
-\item \file{fleqn.clo} for left aligned equations.
-\item \file{graphicx.sty} for graphics inclusion.
-\item \file{txfonts.sty} optional font package, if document is to
-  be formatted with Times and compatible math fonts.
-\item \file{hyperref.sty} optional packages if hyper linking is
-  required in the document.
-
-\end{enumerate}
-
-All the above packages are part of any standard \LaTeX{} installation.
-Therefore, the users need not be bothered about downloading any
-extra packages.  Further, users are free to make use of \textsc{ams}
-math packages like, \file{amsmath.sty}, \file{amsthm.sty},
-\file{amssymb.sty}, \file{amsfonts.sty}, etc., if they want.  All
-these packages work in tandem with \file{elsarticle.cls} without
-any problems.
-
-\section{Major Differences}
-\hypertarget{majordifferences}{}
-
-Following are the major differences between \file{elsarticle.cls}
-and its predecesor package, \file{elsart.cls}:
-
-\begin{enumerate}[\textbullet]
-
-\item \file{elsarticle.cls} is built upon \file{article.cls}
-	while \file{elsart.cls} is not. \file{elsart.cls} redefines
-	many of the commands in the \LaTeX{} classes/kernel, which can
-	possibly cause surprising clashes with other contributed
-	\LaTeX{} packages.
-
-\item Provides preprint document formatting by default, and
-	optionally formats the document as per the final
-	style of models $1+$, $3+$ and $5+$ of Elsevier journals.
-
-\item Some easier hooks for formatting \verb+list+ and
-	\verb+theorem+ environments are provided while people can still
-	use \file{amsthm.sty} package. 
-
-\item \file{natbib.sty} is the main citation processing package
-  which can comprehensively handle all kinds of citations and
-	works perfectly with \file{hyperref.sty} in combination with
-	\file{hypernat.sty}.
-
-\item Long title pages are processed correctly in preprint and
-  final formats.
-
-\end{enumerate}
-
-\section{Installation}
-\hypertarget{installation}{}
-
-The package is available at
-\url{http://www.elsevier.com/locate/latex}.
-It can also be found in any of the nodes of the Comprehensive
-\TeX{} Archive Network (\textsc{ctan}), one of the primary nodes
-being
-\url{http://www.ctan.org/tex-archive/macros/latex/contrib/elsevier/}.
-Please grab the \file{elsarticle.dtx} which is the composite
-class with documentation and \file{elsarticle.ins} which is the
-\LaTeX{} installer file. When we compile the
-\file{elsarticle.ins} with \LaTeX{} it provides the class file,
-\file{elsarticle.cls} by
-stripping off all the documentation from the \verb+*.dtx+ file.
-The class may be moved or copied to a place, usually,
-\texttt{\$TEXMF/tex/latex/elsevier/}, or a folder which will be read
-by \LaTeX{} during document compilation.  The \TeX{} file
-database needs updation after moving/copying class file.  Usually,
-we use commands like \verb+mktexlsr+ or \verb+texhash+ depending
-upon the distribution and operating system.
-
-%\newpage
-
-\section{Usage}\label{sec:usage}
-\hypertarget{usage}{}
-The class should be loaded with the command:
-
-\begin{vquote}
- \documentclass[<options>]{elsarticle}
-\end{vquote}
-
-where the \verb+options+ can be the following:
-
-\begin{enumerate}[(1)]
-
-\item \verb+preprint+ --- default options which formats the
-  document for submission to Elsevier journals.
-
-\item \verb+review+ --- similar to \verb+preprint+ option, but
-  increases the baselineskip to facilitate easier review process.
-
-\item \verb+1p+ --- formats to the look and feel of the final
-  format of model 1+ journals. This is always single column style.
-
-\item \verb+3p+ --- formats to the look and feel of the final
-  format of model 3+ journals. If the journal is a two column
-	model use \verb+twocolumn+ option in combination.
-
-\item \verb+5p+ --- formats for model 5+ journals. This is always
-  two column style.
-
-\item \verb+authoryear+ --- author-year citation style of
-  \file{natbib.sty}. If you want to add extra options of
-	\file{natbib.sty}, you may use the options as a comma delimited
-	strings as argument to \verb+\biboptions+ command. An example
-	would be:
-\end{enumerate}
-\begin{vquote}
- \biboptions{longnamesfirst,angle,semicolon}
-\end{vquote}
-
-\begin{enumerate}[(1)] \setcounter{enumi}{6}
-\item \verb+number+ --- numbered citation style. Extra options
-  can be loaded with \verb+\biboptions+ command.
-
-\item \verb+longtitle+ --- if front matter is unusually long, use
-  this option to split the title page across pages with correct
-	placing of title and author footnotes in the first page.
-
-\item \verb+times+ --- loads \file{txfonts.sty} if available in
-  the system to use Times and compatible math fonts.
-
-\item All options of \file{article.cls} can be used with this
-  document class.
-
-\item The default options loaded are \verb+a4paper+, \verb+10pt+,
-  \verb+oneside+, \verb+onecolumn+ and \verb+preprint+.
-
-\end{enumerate}
-
-\section{Preamble}
-\hypertarget{preamble}{}
-
-There are two types of preamble coding --- (1) each author is
-connected to an affiliation with a footnote marker; hence all
-authors are grouped together and affiliations follow;  (2) authors
-of same affiliations are grouped together and the relevant
-affiliation follows this group. An example coding of the first
-type is provided below:
-
-\begin{vquote}
- \title{This is a specimen title\tnoteref{t1,t2}}
- \tnotetext[t1]{This document is a collaborative effort.}
- \tnotetext[t2]{The second title footnote which is a longer 
-    longer than the first one and with an intention to fill
-    in up more than one line while formatting.} 
-\end{vquote}
-
-\begin{vquote}
- \author[rvt]{C.V.~Radhakrishnan\corref{cor1}\fnref{fn1}}
- \ead{cvr@river-valley.com}
-
- \author[rvt,focal]{K.~Bazargan\fnref{fn2}}
- \ead{kaveh@river-valley.com}
-
- \author[els]{S.~Pepping\corref{cor2}\fnref{fn1,fn3}}
- \ead[url]{http://www.elsevier.com}
-\end{vquote}
-
-\begin{vquote}
- \cortext[cor1]{Corresponding author}
- \cortext[cor2]{Principal corresponding author}
- \fntext[fn1]{This is the specimen author footnote.}
- \fntext[fn2]{Another author footnote, but a little more longer.}
- \fntext[fn3]{Yet another author footnote. Indeed, you can have
-    any number of author footnotes.}
-\end{vquote}
-
-\begin{vquote}
-
- \address[rvt]{River Valley Technologies, SJP Building,
-    Cotton Hills, Trivandrum, Kerala, India 695014}
- \address[focal]{River Valley Technologies, 9, Browns Court,
-    Kennford, Exeter, United Kingdom}
- \address[els]{Central Application Management,
-    Elsevier, Radarweg 29, 1043 NX\\
-    Amsterdam, Netherlands}

-
-Most of the commands like \verb+\title+, \verb+\author+,
-\verb+\address+ are self explanatory.  Various components are
-linked each other by a label--reference mechanism, for
-instance, title footnote is linked to the title with a footnote
-mark generated by referring to the \verb+\label+ string of
-the \verb=\tnotetext=.  We have used similar commands
-like \verb=\tnoteref= (to link title note to title);
-\verb=\corref= (to link corresponding author text to
-corresponding author); \verb=\fnref= (to link footnote text to
-the relevant author names).  \TeX{} needs two compilations to
-resolve the footnote marks in the preamble part.  Given below are
-the syntax of various note marks and note texts.
-
-\begin{vquote}
-  \tnoteref{<label(s)>}
-  \corref{<label(s)>}
-  \fnref{<label(s)>}
-  \tnotetext[<label>]{<title note text>}
-  \cortext[<label>]{<corresponding author note text>}
-  \fntext[<label>]{<author footnote text>}
-\end{vquote}
-
-\noindent where \verb=<label(s)>= can be either one or more comma
-delimited label strings. The optional arguments to the
-\verb=\author= command holds the ref label(s) of the address(es)
-to which the author is affiliated while each \verb=\address=
-command can have an optional argument of a label. In the same
-manner, \verb=\tnotetext=, \verb=\fntext=, \verb=\cortext= will
-have optional arguments as their respective labels and note text
-as their mandatory argument. 
-

-\section{Floats}
-\hypertarget{floats}{}
-\tooltip{Figures}{mytip6} may be included using the command,
-\verb+\includegraphics+ in combination with or without its
-several options to further control the graphic.
-\verb+\includegraphics+ is provided by \file{graphic[s,x].sty}
-which is part of any standard \LaTeX{} distribution.
-\file{graphicx.sty} is loaded by default. \LaTeX{} accepts
-figures in postscript format while pdf\LaTeX{} accepts
-\file{*.pdf}, \file{*.mps} (metapost), \file{*.jpg} and
-\file{*.png} formats.  pdf\LaTeX{} does not accept
-graphic files in postscript format.
-
-The \verb+table+ environment is handy for marking up tabular
-material. If users want to use \file{multirow.sty},
-\file{array.sty}, etc., to fine control/enhance the tables, they
-are welcome to load any package of their choice and
-\file{elsarticle.cls} will work in combination with all loaded
-packages.

-\section{Theorem and theorem like environments}
-\hypertarget{theorems}{}

-\file{elsarticle.cls} provides a few hooks to format theorems and
-theorem like environments with ease. All commands the options
-that are used with \verb+\newtheorem+ command will work exactly
-in the same manner.  \file{elsarticle.cls} provides three
-commands to format theorem or theorem like environments:
-
-\begin{vquote}
- \newtheorem{thm}{Theorem}
- \newtheorem{lem}[thm]{Lemma}
- \newdefinition{rmk}{Remark}
- \newproof{pf}{Proof}
- \newproof{pot}{Proof of Theorem \ref{thm2}}
-\end{vquote}

-\noindent\textbf{Remark 3.}\enspace
-We remark that; when the ratio $h/\la$ tends to 0, the expression $\la
-L(r,s)=-(s-r)/(4\left(\frac{h}{\la}\right)^2+(r-s)^2)$ tends to
-$1/(r-s)$ which is a singular function. This means that the expression
-$\la L(r,s)$ is not well behaved for the small values of
-$h/\la$. Consequently, for the solution to converge, the integrals of
-(10) and (11) must be evaluated with a large number of
-nodes. In our numerical applications (cf. section 5), we
-use 100 nodes to evaluate these integrals. With the smallest value of
-$h/\la=0.02$, the convergence is good with $N=20$.

-For system (8), consensus can be achieved with
-$\|T_{\omega z}(s)\|_{\infty}<\gamma$ if there exist a symmetric
-positive definite
- matrix $P\in \mathcal{R}^{(n-1)\times (n-1)}$ and a scalar $\mu>0$ satisfying
-\setcounter{equation}{9}
-\begin{eqnarray}\label{10}

-common Lyapunov function $V(\delta)=\delta^T(t)P\delta(t)$ (see
-the proof of Lemma 3 in Appendix A). \hfill$\square$
-\end{toolwrite}
-
-\tooltip{\ttfamily\bs newtheorem}{mytip2} command formats a
-theorem in \LaTeX's default style with italicized font, bold font
-for theorem heading, theorem number at the right hand side of the
-theorem heading.  It also optionally accepts an argument which
-will be printed as an extra heading in parentheses. You may roll
-over your \tooltip{mouse here}{mytip2} to see how some text
-enclosed between \verb+\begin{thm}+ \dots \verb+\end{thm}+ will
-look like.
-
-\tooltip{\ttfamily\bs newdefinition}{mytip1} command is same in
-all respects as its \verb+\newtheorem+ counterpart except that
-the font shape is roman instead of italic.  Both
-\verb+\newdefinition+ and \verb+\newtheorem+ commands
-automatically defines counters for the environments defined.
-\tooltip{See the output of}{mytip1} of \verb+\begin{rmk}+ \dots
-\verb+\end{rmk}+.
-
-\tooltip{\ttfamily\bs newproof}{mytip3} command is for defining
-proof environments with upright font shape.  No counters are
-defined. \tooltip{See the output of}{mytip3} \verb+\begin{pot}+
-\dots \verb+\end{pot}+. 
-
-Users can also make use of \verb+amsthm.sty+ which will override
-all the default definitions described above.
-
-\section{Enumerated and Itemized Lists}
-\hypertarget{lists}{}
-\file{elsarticle.cls} provides an extended list processing macros
-which makes the usage a bit more user friendly than the default
-\LaTeX{} list macros.   With an optional argument to the
-\verb+\begin{enumerate}+ command, you can change the list counter
-type and its attributes.
-
-\begin{vquote}
- \begin{enumerate}[1.]
- \item The enumerate environment starts with an optional
-   argument `1.' so that the item counter will be suffixed
-   by a period.
- \item If you provide a closing parenthesis to the number in the
-   optional argument, the output will have closing parenthesis
-   for all the item counters.  
- \item You can use `(a)' for alphabetical counter and '(i)' for
-   roman counter.
-\end{vquote}
-
-\begin{vquote}
-  \begin{enumerate}[a)]
-    \item Another level of list with alphabetical counter.
-    \item One more item before we start another.
-    \begin{enumerate}[(i)]
-     \item This item has roman numeral counter.
-     \item Another one before we close the third level.
-    \end{enumerate}
-    \item Third item in second level.
-  \end{enumerate}
- \item All list items conclude with this step.

-   counters.

-
-You can see the typeset copy of the above source code if you
-roll over \tooltip{your mouse here}{mytip4}.

-Further, the enhanced list environment allows one to prefix a
-string like `step' to all the item numbers.  Take a look at the
-example below:
-
-\begin{vquote}
- \begin{enumerate}[Step 1.]
-  \item This is the first step of the example list.

-\section{Cross-references}
-\hypertarget{crossreferences}{}
-
-In electronic publications articles may be internally
-hyperlinked. Hyperlinks are generated from proper
-cross-references in the article.  For example, the words
-\textcolor{black!80}{Fig.~1} will never be more than simple text,
-whereas the proper cross-reference \verb+\ref{tiger}+ may be
-turned into a hyperlink to the figure itself:
-\tooltip{Fig.~1}{mytip6}.  In the same way,
-the words \tooltip{Ref.~[1]}{mytip7} will fail to turn into a
-hyperlink; the proper cross-reference is \verb+\cite{Knuth96}+.
-Cross-referencing is possible in \LaTeX{} for sections,
-subsections, formulae, figures, tables, and literature
-references.
-
-
-\section{Mathematical symbols and formulae}
-\hypertarget{math}{}
-
-Many physical/mathematical sciences authors require more
-mathematical symbols than the few that are provided in standard
-\LaTeX. A useful package for additional symbols is the
-\file{amssymb} package, developed by the American Mathematical
-Society. This package includes such oft used symbols as
-\verb+\lesssim+ for $\lesssim$, \verb+\gtrsim+ for $\gtrsim$ or
-\verb+\hbar+ for $\hbar$. Note that your \TeX{} system should
-have the \file{msam} and \file{msbm} fonts installed. If you need
-only a few symbols, such as \verb+\Box+ for $\square$, you might
-try the package \file{latexsym}.
-
-Another point which would require authors' attention is the
-breaking of longer equations.  When you use
-\file{elsarticle.cls} for formatting your submissions in 
-\verb+preprint+ mode, the document is formatted in single column
-style with a text width of 384pt or 5.3in.  When this document is
-formatted for final print and if the journal happens to be a double column
-journal, the text width will be reduced to 224pt at for 3+
-double column and 5+ journals respectively. All the nifty fine
-tuning in equation breaking done by the author goes to waste in
-such cases.  Therefore, authors are requested to check this
-problem by typesetting their submissions in final format as well
-just to see if their equations are broken at appropriate places,
-by changing appropriate options in the document class loading
-command, which is explained in section~\ref{sec:usage},
-\nameref{sec:usage}. This allows authors to fix any equation breaking
-problem before submission for publication.
-\file{elsarticle.cls} supports formatting the author submission
-in different types of final format.  This is further discussed in
-section \ref{sec:final}, \nameref{sec:final}.
-
-
-\section{Bibliography}
-\hypertarget{bibliography}{}
-
-Three bibliographic style files (\verb+*.bst+) are provided ---
-\file{elsarticle-num.bst}, \file{elsarticle-num-names.bst} and
-\file{elsarticle-harv.bst} --- the first one for numbered scheme, the
-second for numbered with new options of \file{natbib.sty} and the
-last one for author year scheme.
-
-In \LaTeX{} literature references are listed in the
-thebibliography environment.  Each reference is a
-\verb+\bibitem+; each \verb+\bibitem+ is identified by a label,
-by which it can be cited in the text: 
-\verb+\bibitem[Elson et al.(1996)]{ESG96}+ is cited as 
-\verb+\citet{ESG96}+. In connection with cross-referencing and
-possible future hyperlinking it is not a good idea to collect
-more that one literature item in one \verb+\bibitem+.  The
-so-called Harvard or author-year style of referencing is enabled
-by the \LaTeX{} package \file{natbib}. With this package the
-literature can be cited as follows: 
-
-\begin{enumerate}[\textbullet]
-\item Parenthetical: \verb+\citep{WB96}+ produces (Wettig \&
-  Brown, 1996).
-\item Textual: \verb+\citet{ESG96}+ produces Elson et al. (1996).
-\item An affix and part of a reference:
-	\verb+\citep[e.g.][Ch. 2]{Gea97}+ produces (e.g. Governato et
-	al., 1997, Ch. 2).
-\end{enumerate}
-
-In the numbered scheme of citation, \verb+\cite{<label>}+ is used,
-since \verb+\citep+ or \verb+\citet+ has no relevance in numbered
-scheme.  \file{natbib} package is loaded by \file{elsarticle} with
-\verb+numbers+ as default option.  You can change this to author-year
-or harvard scheme by adding option \verb+authoryear+ in the class
-loading command.  If you want to use more options of the \file{natbib}
-package, you can do so with the \verb+\biboptions+ command, which is
-described in section \ref{sec:usage}, \nameref{sec:usage}.  For
-details of various options of the \file{natbib} package, please take a
-look at the \file{natbib} documentation, which is part of any standard
-\LaTeX{} installation.

-\section{Final print}\label{sec:final}
-\hypertarget{final}{}
-
-Authors can format their submission to the page size and margins
-of their preferred journal.  \file{elsarticle} provides four
-class options for the same:
-\lmrgn=3em
-\begin{enumerate}
-\item [\texttt{1p}:] $1+$ journals with a text area of
-384pt $\times$ 562pt or 13.5cm $\times$ 19.75cm or 5.3in $\times$
-7.78in, single column style only.
-
-\item [\texttt{3p}:] $3+$ journals with a text area of 468pt
-$\times$ 622pt or 16.45cm $\times$ 21.9cm or 6.5in $\times$
-8.6in, single column style.
-
-\item [\texttt{3pd}:] $3+$ with the same text area as above,
-double column style.
-
-\item [\texttt{5p}:] $5+$ with text area of 522pt $\times$
-682pt or 18.35cm $\times$ 24cm or 7.22in $\times$ 9.45in, 
-double column style only.
-\end{enumerate}
-
-Following pages have the clippings of different parts of 
-the first page of different journal models typeset in final
-format.

-Model $1+$ and $3+$  will have the same look and
-feel in the typeset copy when presented in this document. That is
-also the case with the double column $3+$ and $5+$ journal article
-pages. The only difference will be wider text width of 
-higher models.  Therefore we will look at the
-different portions of a typical single column journal page and
-that of a double column article in the final format.
-

-\includeclip{1}{60 93 536 600}{els-3pd.pdf}
-\def\rulecolor{orange}
-
-\subsection*{Displayed equations and double column journals}
-
-Many Elsevier journals print their text in two columns. Because
-the preprint layout uses a larger line width than such columns,
-the formulas are too wide for the line width in print. Here is an
-example of an equation  (see equation 6) which is perfect in
-single column preprint format:
-
-\bigskip
-\src{See equation (6)}
-\def\rulecolor{blue!70}
-\includeclip{4}{134 391 483 594}{els1.pdf}
-\def\rulecolor{orange}
-
-\bigskip
-\noindent When this document is typeset for publication in a
-model 3+ journal with double columns, the equation will overlap
-the second column text matter if the equation is not broken at
-the appropriate location.
-
-\newpage\vspace*{-18pt}
-\def\rulecolor{blue!70}
-\src{See equation (6) overprints into second column}
-\includeclip{3}{61 531 532 734}{els-3pd.pdf}
-\def\rulecolor{orange}
-
-\medskip
-
-\noindent The typesetter will try to break the equation which
-need not necessarily be to the liking of the author or as it
-happens, typesetter's break point may be semantically incorrect.
-Therefore, authors may check their submissions for the incidence
-of such long equations and break the equations at the correct
-places so that the final typeset copy will be as they wish.

- %% This bibliography style file is intended for texts in ENGLISH
- %% This is an author-year citation style bibliography. As such, it is
- %% non-standard LaTeX, and requires a special package file
- %% to function properly.
- %% Such a package is    natbib.sty   by Patrick W. Daly
- %% The form of the \bibitem entries is
- %%   \bibitem[Jones et al.(1990)]{key}...
- %%   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
- %% The essential feature is that the label (the part in brackets) consists
- %% of the author names, as they should appear in the citation, with the year
- %% in parentheses following. There must be no space before the opening
- %% parenthesis!
- %% With natbib v5.3, a full list of authors may also follow the year.
- %% In natbib.sty, it is possible to define the type of enclosures that is
- %% really wanted (brackets or parentheses), but in either case, there must
- %% be parentheses in the label.
- %% The \cite command functions as follows:
- %%   \citet{key} ==>>                Jones et al. (1990)
- %%   \citet*{key} ==>>               Jones, Baker, and Smith (1990)
- %%   \citep{key} ==>>                (Jones et al., 1990)
- %%   \citep*{key} ==>>               (Jones, Baker, and Smith, 1990)
- %%   \citep[chap. 2]{key} ==>>       (Jones et al., 1990, chap. 2)
- %%   \citep[e.g.][]{key} ==>>        (e.g. Jones et al., 1990)
- %%   \citep[e.g.][p. 32]{key} ==>>   (e.g. Jones et al., p. 32)
- %%   \citeauthor{key} ==>>           Jones et al.
- %%   \citeauthor*{key} ==>>          Jones, Baker, and Smith
- %%   \citeyear{key} ==>>             1990

-\section{Introduction}
-\hypertarget{introduction}{}
-
-\file{elsarticle.cls} is a thoroughly re-written document class
-for formatting \LaTeX{} submissions to Elsevier journals.
-The class uses the environments and commands defined in \LaTeX{} kernel
-without change to the signature so that clashes with other
-contributed \LaTeX{} packages like \file{hyperref.sty},
-\file{preview-latex.sty}, etc., will be minimal.
-\file{elsarticle.cls} is primarily built upon the default
-\file{article.cls}.  The class depends on the following packages
-for its proper functionality:
-
-\begin{enumerate}[1.]
-
-\item \file{pifont.sty} for openstar in the title footnotes.
-\item \file{natbib.sty} for citation processing.
-\item \file{geometry.sty} for margin settings.
-\item \file{fleqn.clo} for left aligned equations.
-\item \file{graphicx.sty} for graphics inclusion.
-\item \file{txfonts.sty} optional font package, if document is to
-  be formatted with Times and compatible math fonts.
-\item \file{hyperref.sty} optional packages if hyper linking is
-  required in the document.
-
-\end{enumerate}
-
-All the above packages are part of any standard \LaTeX{} installation.
-Therefore, the users need not be bothered about downloading any
-extra packages.  Further, users are free to make use of \textsc{ams}
-math packages like, \file{amsmath.sty}, \file{amsthm.sty},
-\file{amssymb.sty}, \file{amsfonts.sty}, etc., if they want.  All
-these packages work in tandem with \file{elsarticle.cls} without
-any problems.
-
-\section{Major Differences}
-\hypertarget{majordifferences}{}
-
-Following are the major differences between \file{elsarticle.cls}
-and its predecesor package, \file{elsart.cls}:
-
-\begin{enumerate}[\textbullet]
-
-\item \file{elsarticle.cls} is built upon \file{article.cls}
-while \file{elsart.cls} is not. \file{elsart.cls} redefines
-many of the commands in the \LaTeX{} classes/kernel, which can
-possibly cause surprising clashes with other contributed
-\LaTeX{} packages.
-
-\item Provides preprint document formatting by default, and
-optionally formats the document as per the final
-style of models $1+$, $3+$ and $5+$ of Elsevier journals.
-
-\item Some easier hooks for formatting \verb+list+ and
-\verb+theorem+ environments are provided while people can still
-use \file{amsthm.sty} package.
-
-\item \file{natbib.sty} is the main citation processing package
-  which can comprehensively handle all kinds of citations and
-works perfectly with \file{hyperref.sty} in combination with
-\file{hypernat.sty}.
-
-\item Long title pages are processed correctly in preprint and
-  final formats.
-
-\end{enumerate}
-
-\section{Installation}
-\hypertarget{installation}{}
-
-The package is available at
-\url{http://www.elsevier.com/locate/latex}.
-It can also be found in any of the nodes of the Comprehensive
-\TeX{} Archive Network (\textsc{ctan}), one of the primary nodes
-being
-\url{http://www.ctan.org/tex-archive/macros/latex/contrib/elsevier/}.
-Please grab the \file{elsarticle.dtx} which is the composite
-class with documentation and \file{elsarticle.ins} which is the
-\LaTeX{} installer file. When we compile the
-\file{elsarticle.ins} with \LaTeX{} it provides the class file,
-\file{elsarticle.cls} by
-stripping off all the documentation from the \verb+*.dtx+ file.
-The class may be moved or copied to a place, usually,
-\texttt{\$TEXMF/tex/latex/elsevier/}, or a folder which will be read
-by \LaTeX{} during document compilation.  The \TeX{} file
-database needs updation after moving/copying class file.  Usually,
-we use commands like \verb+mktexlsr+ or \verb+texhash+ depending
-upon the distribution and operating system.
-
-
-\section{Usage}\label{sec:usage}
-\hypertarget{usage}{}
-The class should be loaded with the command:
-
-\begin{vquote}
- \documentclass[<options>]{elsarticle}
-\end{vquote}
-
-where the \verb+options+ can be the following:
-
-\begin{enumerate}[(1)]
-
-\item \verb+preprint+ --- default options which formats the
-  document for submission to Elsevier journals.
-
-\item \verb+review+ --- similar to \verb+preprint+ option, but
-  increases the baselineskip to facilitate easier review process.
-
-\item \verb+1p+ --- formats to the look and feel of the final
-  format of model 1+ journals. This is always single column style.
-
-\item \verb+3p+ --- formats to the look and feel of the final
-  format of model 3+ journals. If the journal is a two column
-model use \verb+twocolumn+ option in combination.
-
-\item \verb+5p+ --- formats for model 5+ journals. This is always
-  two column style.
-
-\item \verb+authoryear+ --- author-year citation style of
-  \file{natbib.sty}. If you want to add extra options of
-\file{natbib.sty}, you may use the options as a comma delimited
-strings as argument to \verb+\biboptions+ command. An example
-would be:
-\end{enumerate}
-\begin{vquote}
- \biboptions{longnamesfirst,angle,semicolon}
-\end{vquote}
-
-\begin{enumerate}[(1)] \setcounter{enumi}{6}
-\item \verb+number+ --- numbered citation style. Extra options
-  can be loaded with \verb+\biboptions+ command.
-
-\item \verb+longtitle+ --- if front matter is unusually long, use
-  this option to split the title page across pages with correct
-placing of title and author footnotes in the first page.
-
-\item \verb+times+ --- loads \file{txfonts.sty} if available in
-  the system to use Times and compatible math fonts.
-
-\item All options of \file{article.cls} can be used with this
-  document class.
-
-\item The default options loaded are \verb+a4paper+, \verb+10pt+,
-  \verb+oneside+, \verb+onecolumn+ and \verb+preprint+.
-
-\end{enumerate}
-
-\section{Preamble}
-\hypertarget{preamble}{}
-
-There are two types of preamble coding --- (1) each author is
-connected to an affiliation with a footnote marker; hence all
-authors are grouped together and affiliations follow;  (2) authors
-of same affiliations are grouped together and the relevant
-affiliation follows this group. An example coding of the first
-type is provided below:
-
-\begin{vquote}
- \title{This is a specimen title\tnoteref{t1,t2}}
- \tnotetext[t1]{This document is a collaborative effort.}
- \tnotetext[t2]{The second title footnote which is a longer
-    longer than the first one and with an intention to fill
-    in up more than one line while formatting.}
-\end{vquote}
-
-\begin{vquote}
- \author[rvt]{C.V.~Radhakrishnan\corref{cor1}\fnref{fn1}}

- \cortext[cor2]{Principal corresponding author}
- \fntext[fn1]{This is the specimen author footnote.}
- \fntext[fn2]{Another author footnote, but a little more longer.}
- \fntext[fn3]{Yet another author footnote. Indeed, you can have
-    any number of author footnotes.}

-
-Most of the commands like \verb+\title+, \verb+\author+,
-\verb+\address+ are self explanatory.  Various components are
-linked each other by a label--reference mechanism, for
-instance, title footnote is linked to the title with a footnote
-mark generated by referring to the \verb+\label+ string of
-the \verb=\tnotetext=.  We have used similar commands
-like \verb=\tnoteref= (to link title note to title);
-\verb=\corref= (to link corresponding author text to
-corresponding author); \verb=\fnref= (to link footnote text to
-the relevant author names).  \TeX{} needs two compilations to
-resolve the footnote marks in the preamble part.  Given below are
-the syntax of various note marks and note texts.
-
-\begin{vquote}
-  \tnoteref{<label(s)>}
-  \corref{<label(s)>}
-  \fnref{<label(s)>}
-  \tnotetext[<label>]{<title note text>}
-  \cortext[<label>]{<corresponding author note text>}
-  \fntext[<label>]{<author footnote text>}
-\end{vquote}
-
-\noindent where \verb=<label(s)>= can be either one or more comma
-delimited label strings. The optional arguments to the
-\verb=\author= command holds the ref label(s) of the address(es)
-to which the author is affiliated while each \verb=\address=
-command can have an optional argument of a label. In the same
-manner, \verb=\tnotetext=, \verb=\fntext=, \verb=\cortext= will
-have optional arguments as their respective labels and note text
-as their mandatory argument.
-
-The following example code provides the markup of the second type
-of author-affiliation as seen in the output given in the
-box to the right.

-\end{vquote}
-
-The preamble part has further environments like
-\verb+\begin{abstract}+ \dots \linebreak \verb+\end{abstract}+ and
-\verb+\begin{keyword}+ \verb+...+ \verb+\end{keyword}+ which
-contain the abstract and keywords respectively. Keywords can be
-marked up in the following manner:
-
-\begin{vquote}
- \begin{keyword}
-  quadruple exiton \sep polariton \sep WGM
-
-  \PACS 71.35.-y \sep 71.35.Lk \sep 71.36.+c
- \end{keyworkd}
-\end{vquote}
-
-\noindent Each keyword shall be separated by \verb+\sep+ command.
-\textsc{pacs} and \textsc{msc} classifications shall be provided in
-the keyword environment with the commands \verb+\PACS+ and
-\verb+\MSC+ respectively.  \verb+\MSC+ accepts an optional
-argument to accommodae future revisions.
-eg., \verb=\MSC[2008]=. The default is 2000.

-\section{Floats}
-\hypertarget{floats}{}
-\tooltip{Figures}{mytip6} may be included using the command,
-\verb+\includegraphics+ in combination with or without its
-several options to further control the graphic.
-\verb+\includegraphics+ is provided by \file{graphic[s,x].sty}
-which is part of any standard \LaTeX{} distribution.
-\file{graphicx.sty} is loaded by default. \LaTeX{} accepts
-figures in postscript format while pdf\LaTeX{} accepts
-\file{*.pdf}, \file{*.mps} (metapost), \file{*.jpg} and
-\file{*.png} formats.  pdf\LaTeX{} does not accept
-graphic files in postscript format.
-
-The \verb+table+ environment is handy for marking up tabular
-material. If users want to use \file{multirow.sty},
-\file{array.sty}, etc., to fine control/enhance the tables, they
-are welcome to load any package of their choice and
-\file{elsarticle.cls} will work in combination with all loaded
-packages.
-
-\section{Theorem and theorem like environments}
-\hypertarget{theorems}{}
-1
-\file{elsarticle.cls} provides a few hooks to format theorems and
-theorem like environments with ease. All commands the options
-that are used with \verb+\newtheorem+ command will work exactly
-in the same manner.  \file{elsarticle.cls} provides three
-commands to format theorem or theorem like environments:
-
-\begin{vquote}
- \newtheorem{thm}{Theorem}
- \newtheorem{lem}[thm]{Lemma}
- \newdefinition{rmk}{Remark}
- \newproof{pf}{Proof}
- \newproof{pot}{Proof of Theorem \ref{thm2}}
-\end{vquote}
-

-\begin{toolwrite}{15cm}
-\let\la\lambda
-\noindent\textbf{Remark 3.}\enspace
-We remark that; when the ratio $h/\la$ tends to 0, the expression $\la
-L(r,s)=-(s-r)/(4\left(\frac{h}{\la}\right)^2+(r-s)^2)$ tends to
-$1/(r-s)$ which is a singular function. This means that the expression
-$\la L(r,s)$ is not well behaved for the small values of
-$h/\la$. Consequently, for the solution to converge, the integrals of
-(10) and (11) must be evaluated with a large number of
-nodes. In our numerical applications (cf. section 5), we
-use 100 nodes to evaluate these integrals. With the smallest value of
-$h/\la=0.02$, the convergence is good with $N=20$.

-the proof of Lemma 3 in Appendix A). \hfill$\square$
-\end{toolwrite}
-
-\tooltip{\ttfamily\bs newtheorem}{mytip2} command formats a
-theorem in \LaTeX's default style with italicized font, bold font
-for theorem heading, theorem number at the right hand side of the
-theorem heading.  It also optionally accepts an argument which
-will be printed as an extra heading in parentheses. You may roll
-over your \tooltip{mouse here}{mytip2} to see how some text
-enclosed between \verb+\begin{thm}+ \dots \verb+\end{thm}+ will
-look like.
-
-\tooltip{\ttfamily\bs newdefinition}{mytip1} command is same in
-all respects as its \verb+\newtheorem+ counterpart except that
-the font shape is roman instead of italic.  Both
-\verb+\newdefinition+ and \verb+\newtheorem+ commands
-automatically defines counters for the environments defined.
-\tooltip{See the output of}{mytip1} of \verb+\begin{rmk}+ \dots
-\verb+\end{rmk}+.
-
-\tooltip{\ttfamily\bs newproof}{mytip3} command is for defining
-proof environments with upright font shape.  No counters are
-defined. \tooltip{See the output of}{mytip3} \verb+\begin{pot}+
-\dots \verb+\end{pot}+.
-
-Users can also make use of \verb+amsthm.sty+ which will override
-all the default definitions described above.
-
-\section{Enumerated and Itemized Lists}
-\hypertarget{lists}{}
-\file{elsarticle.cls} provides an extended list processing macros
-which makes the usage a bit more user friendly than the default
-\LaTeX{} list macros.   With an optional argument to the
-\verb+\begin{enumerate}+ command, you can change the list counter
-type and its attributes.
-
-\begin{vquote}
- \begin{enumerate}[1.]
- \item The enumerate environment starts with an optional
-   argument `1.' so that the item counter will be suffixed
-   by a period.
- \item If you provide a closing parenthesis to the number in the
-   optional argument, the output will have closing parenthesis
-   for all the item counters.
- \item You can use `(a)' for alphabetical counter and '(i)' for
-   roman counter.
-\end{vquote}
-
-\begin{vquote}
-  \begin{enumerate}[a)]
-    \item Another level of list with alphabetical counter.
-    \item One more item before we start another.
-    \begin{enumerate}[(i)]
-     \item This item has roman numeral counter.
-     \item Another one before we close the third level.
-    \end{enumerate}
-    \item Third item in second level.
-  \end{enumerate}
- \item All list items conclude with this step.
- \end{enumerate}
-\end{vquote}
-%%
-%% Mytool 4
-%%
-\begin{toolwrite}{15cm}
- \begin{enumerate}[1.]
- \item The enumerate environment starts with an optional
-   argument `1.' so that the item counter will be suffixed
-   by a period.
- \item If you provide  parentheses to the number, the
-   output will have only one parentheses for all the item
-   counters.
- \item You can use `(a)' for alphabetical counter and '(i)' for
-   roman counter.
-  \begin{enumerate}[a)]
-    \item Another level of list with alphabetical counter.
-    \item One more item before we start another.
-    \begin{enumerate}[(i)]
-     \item This item has roman numeral counter.
-     \item Another one before we close the third level.
-    \end{enumerate}
-    \item Third item in second level.
-  \end{enumerate}
- \item All list items conclude with this step.
-\end{enumerate}
-\end{toolwrite}
-
-You can see the typeset copy of the above source code if you
-roll over \tooltip{your mouse here}{mytip4}.
-
-Further, the enhanced list environment allows one to prefix a
-string like `step' to all the item numbers.  Take a look at the
-example below:
-
-\begin{vquote}
- \begin{enumerate}[Step 1.]
-  \item This is the first step of the example list.
-  \item Obviously this is the second step.
-  \item The final step to wind up this example.

-
-\tooltip{Here is the typeset output}{mytip5} of the above example code.

-\section{Cross-references}
-\hypertarget{crossreferences}{}
-
-In electronic publications articles may be internally
-hyperlinked. Hyperlinks are generated from proper
-cross-references in the article.  For example, the words
-\textcolor{black!80}{Fig.~1} will never be more than simple text,
-whereas the proper cross-reference \verb+\ref{tiger}+ may be
-turned into a hyperlink to the figure itself:
-\tooltip{Fig.~1}{mytip6}.  In the same way,
-the words \tooltip{Ref.~[1]}{mytip7} will fail to turn into a
-hyperlink; the proper cross-reference is \verb+\cite{Knuth96}+.
-Cross-referencing is possible in \LaTeX{} for sections,
-subsections, formulae, figures, tables, and literature
-references.
-
-\section{Mathematical symbols and formulae}
-\hypertarget{math}{}
-
-Many physical/mathematical sciences authors require more
-mathematical symbols than the few that are provided in standard
-\LaTeX. A useful package for additional symbols is the
-\file{amssymb} package, developed by the American Mathematical
-Society. This package includes such oft used symbols as
-\verb+\lesssim+ for $\lesssim$, \verb+\gtrsim+ for $\gtrsim$ or
-\verb+\hbar+ for $\hbar$. Note that your \TeX{} system should
-have the \file{msam} and \file{msbm} fonts installed. If you need
-only a few symbols, such as \verb+\Box+ for $\square$, you might
-try the package \file{latexsym}.
-
-Another point which would require authors' attention is the
-breaking of longer equations.  When you use
-\file{elsarticle.cls} for formatting your submissions in
-\verb+preprint+ mode, the document is formatted in single column
-style with a text width of 384pt or 5.3in.  When this document is
-formatted for final print and if the journal happens to be a double column
-journal, the text width will be reduced to 224pt at for 3+
-double column and 5+ journals respectively. All the nifty fine
-tuning in equation breaking done by the author goes to waste in
-such cases.  Therefore, authors are requested to check this
-problem by typesetting their submissions in final format as well
-just to see if their equations are broken at appropriate places,
-by changing appropriate options in the document class loading
-command, which is explained in section~\ref{sec:usage},
-\nameref{sec:usage}. This allows authors to fix any equation breaking
-problem before submission for publication.
-\file{elsarticle.cls} supports formatting the author submission
-in different types of final format.  This is further discussed in
-section \ref{sec:final}, \nameref{sec:final}.
-
-\section{Bibliography}
-\hypertarget{bibliography}{}
-
-Three bibliographic style files (\verb+*.bst+) are provided ---
-\file{elsarticle-num.bst}, \file{elsarticle-num-names.bst} and
-\file{elsarticle-harv.bst} --- the first one for numbered scheme, the
-second for numbered with new options of \file{natbib.sty} and the
-last one for author year scheme.
-
-In \LaTeX{} literature references are listed in the
-thebibliography environment.  Each reference is a
-\verb+\bibitem+; each \verb+\bibitem+ is identified by a label,
-by which it can be cited in the text:
-\verb+\bibitem[Elson et al.(1996)]{ESG96}+ is cited as
-\verb+\citet{ESG96}+. In connection with cross-referencing and
-possible future hyperlinking it is not a good idea to collect
-more that one literature item in one \verb+\bibitem+.  The
-so-called Harvard or author-year style of referencing is enabled
-by the \LaTeX{} package \file{natbib}. With this package the
-literature can be cited as follows:
-
-\begin{enumerate}[\textbullet]
-\item Parenthetical: \verb+\citep{WB96}+ produces (Wettig \&
-  Brown, 1996).
-\item Textual: \verb+\citet{ESG96}+ produces Elson et al. (1996).
-\item An affix and part of a reference:
-\verb+\citep[e.g.][Ch. 2]{Gea97}+ produces (e.g. Governato et
-al., 1997, Ch. 2).
-\end{enumerate}
-
-In the numbered scheme of citation, \verb+\cite{<label>}+ is used,
-since \verb+\citep+ or \verb+\citet+ has no relevance in numbered
-scheme.  \file{natbib} package is loaded by \file{elsarticle} with
-\verb+numbers+ as default option.  You can change this to author-year
-or harvard scheme by adding option \verb+authoryear+ in the class
-loading command.  If you want to use more options of the \file{natbib}
-package, you can do so with the \verb+\biboptions+ command, which is
-described in section \ref{sec:usage}, \nameref{sec:usage}.  For
-details of various options of the \file{natbib} package, please take a
-look at the \file{natbib} documentation, which is part of any standard

-\section{Final print}\label{sec:final}
-\hypertarget{final}{}
-
-Authors can format their submission to the page size and margins
-of their preferred journal.  \file{elsarticle} provides four
-class options for the same:
-\lmrgn=3em
-\begin{enumerate}
-\item [\texttt{1p}:] $1+$ journals with a text area of
-384pt $\times$ 562pt or 13.5cm $\times$ 19.75cm or 5.3in $\times$
-7.78in, single column style only.
-
-\item [\texttt{3p}:] $3+$ journals with a text area of 468pt
-$\times$ 622pt or 16.45cm $\times$ 21.9cm or 6.5in $\times$
-8.6in, single column style.
-
-\item [\texttt{3pd}:] $3+$ with the same text area as above,
-double column style.
-
-\item [\texttt{5p}:] $5+$ with text area of 522pt $\times$
-682pt or 18.35cm $\times$ 24cm or 7.22in $\times$ 9.45in,
-double column style only.
-\end{enumerate}
-
-Following pages have the clippings of different parts of
-the first page of different journal models typeset in final
-format.
-
-\bigskip
-\mywidth=14cm
-\def\rulecolor{blue!70}
-\src{Upper part of first page of a single column article}
-\includeclip{1}{104 510 492 712}{els-1p.pdf}
-\def\rulecolor{orange}

-\def\rulecolor{orange}

-\medskip
-
-\noindent
-Model $1+$ and $3+$  will have the same look and
-feel in the typeset copy when presented in this document. That is
-also the case with the double column $3+$ and $5+$ journal article
-pages. The only difference will be wider text width of
-higher models.  Therefore we will look at the
-different portions of a typical single column journal page and
-that of a double column article in the final format.
-
-\newpage
-\vspace*{-18pt}
-\def\rulecolor{blue!70}

-\includeclip{1}{60 93 536 600}{els-3pd.pdf}
-\def\rulecolor{orange}
-
-\subsection*{Displayed equations and double column journals}
-
-Many Elsevier journals print their text in two columns. Because
-the preprint layout uses a larger line width than such columns,
-the formulas are too wide for the line width in print. Here is an
-example of an equation  (see equation 6) which is perfect in
-single column preprint format:
-
-\bigskip
-\src{See equation (6)}
-\def\rulecolor{blue!70}
-\includeclip{4}{134 391 483 594}{els1.pdf}
-\def\rulecolor{orange}
-
-\bigskip
-\noindent When this document is typeset for publication in a
-model 3+ journal with double columns, the equation will overlap
-the second column text matter if the equation is not broken at
-the appropriate location.
-
-\newpage\vspace*{-18pt}
-\def\rulecolor{blue!70}
-\src{See equation (6) overprints into second column}
-\includeclip{3}{61 531 532 734}{els-3pd.pdf}
-\def\rulecolor{orange}
-
-\medskip
-
-\noindent The typesetter will try to break the equation which
-need not necessarily be to the liking of the author or as it
-happens, typesetter's break point may be semantically incorrect.
-Therefore, authors may check their submissions for the incidence
-of such long equations and break the equations at the correct
-places so that the final typeset copy will be as they wish.
