+cas-sc.cls and cas-dc.cls are the two new class files created
+for typesetting Elsevier's journal articles which go through
+Complex Article Service (CAS) workflow. These are now accepted for
+submitting articles, both in Elsevier's electronic submission system
+and elsewhere.
+
+Bugs and problems with elsarticle.cls may be reported to the
+developers of the class via elsarticle@stmdocs.in.
+
+The file manifest.txt provides a list of the files in the
+elsarticle-cas bundle.  The following are the main files available:
+
+- cas-sc-template.tex, template file for single column journals
+- cas-dc-template.tex, template file for double column journals
+- cas-sc-template.pdf, PDF of the cas-sc-template.tex 
+- cas-dc-template.pdf, PDF of the cas-ddc-template.tex
+- cas-common.sty, additional macro package for formatting
+  model2-names.bst, BibTeX style file
+- twitter.jpeg, linkedin.jpeg, url.jpeg, gplus.jpeg, facebook.jpeg,
+  email.jpeg - thumbnail images of social networking sites
+
+The documentation file is elsdoc-cas.tex in the doc directory.  To
+compile it:
+
+1. pdflatex elsdoc-cas
+2. pdflatex elsdoc-cas
+3. pdflatex elsdoc-cas
+
+or
+
+use the makefile. Use the target `all' (eg: make all) in doc
+directory.
+
+The above procedure will create a print version, namely elsdoc-cas.pdf.
+
+Copyright 2019, Elsevier. Bugs, feature requests, suggestions and
+comments may be mailed to elsarticle@stmdocs.in. elsarticle.cls,
+related documentation and supporting packages are released under the
+LATEX Project Public Licence, either version 1.3 or any later
+version. This work has the LPPL maintenance status
+'author-maintained'.

+\section{Introduction}
+
+The Elsevier cas-dc class is based on the
+standard article class and supports almost all of the functionality of
+that class. In addition, it features commands and options to format the
+\begin{itemize} \item document style \item baselineskip \item front
+matter \item keywords and MSC codes \item theorems, definitions and
+proofs \item lables of enumerations \item citation style and labeling.
+\end{itemize}
+
+This class depends on the following packages
+for its proper functioning:
+
+\begin{enumerate}
+\itemsep=0pt
+\item {natbib.sty} for citation processing;
+\item {geometry.sty} for margin settings;
+\item {fleqn.clo} for left aligned equations;
+\item {graphicx.sty} for graphics inclusion;
+\item {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.
+
+\section{Installation}
+
+The package is available at author resources page at Elsevier
+(\url{http://www.elsevier.com/locate/latex}).
+The class may be moved or copied to a place, usually,\linebreak
+\verb+$TEXMF/tex/latex/elsevier/+, %$%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+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{Front matter}
+
+The author names and affiliations could be formatted in two ways:
+\begin{enumerate}[(1)]
+\item Group the authors per affiliation.
+\item Use footnotes to indicate the affiliations.
+\end{enumerate}
+See the front matter of this document for examples. 
+You are recommended to conform your choice to the journal you 
+are submitting to.
+
+\section{Bibliography styles}
+
+There are various bibliography styles available. You can select the
+style of your choice in the preamble of this document. These styles are
+Elsevier styles based on standard styles like Harvard and Vancouver.
+Please use Bib\TeX\ to generate your bibliography and include DOIs
+whenever available.
+
+Here are two sample references: 
+\cite{Fortunato2010}
+\cite{Fortunato2010,NewmanGirvan2004}
+\cite{Fortunato2010,Vehlowetal2013}
+
+\section{Floats}
+{Figures} may be included using the command,\linebreak 
+\verb+\includegraphics+ in
+combination with or without its several options to further control
+graphic. \verb+\includegraphics+ is provided by {graphic[s,x].sty}
+which is part of any standard \LaTeX{} distribution.
+{graphicx.sty} is loaded by default. \LaTeX{} accepts figures in
+the postscript format while pdf\LaTeX{} accepts {*.pdf},
+{*.mps} (metapost), {*.jpg} and {*.png} formats. 
+pdf\LaTeX{} does not accept graphic files in the postscript format. 
+
+\begin{figure}
+	\centering
+		\includegraphics[scale=.75]{figs/Fig1.pdf}
+	\caption{The evanescent light - $1S$ quadrupole coupling
+	($g_{1,l}$) scaled to the bulk exciton-photon coupling
+	($g_{1,2}$). The size parameter $kr_{0}$ is denoted as $x$ and
+	the \PMS is placed directly on the cuprous oxide sample ($\delta
+	r=0$, See also Table \protect\ref{tbl1}).}
+	\label{FIG:1}
+\end{figure}
+
+
+The \verb+table+ environment is handy for marking up tabular
+material. If users want to use {multirow.sty},
+{array.sty}, etc., to fine control/enhance the tables, they
+are welcome to load any package of their choice and
+{cas-dc.cls} will work in combination with all loaded
+packages.
+
+\begin{table}[width=.9\linewidth,cols=4,pos=h]
+\caption{This is a test caption. This is a test caption. This is a test
+caption. This is a test caption.}\label{tbl1}
+\begin{tabular*}{\tblwidth}{@{} LLLL@{} }
+\toprule
+Col 1 & Col 2 & Col 3 & Col4\\
+\midrule
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+\bottomrule
+\end{tabular*}
+\end{table}
+
+\section[Theorem and ...]{Theorem and theorem like environments}
+
+{cas-dc.cls} provides a few shortcuts to format theorems and
+theorem-like environments with ease. In all commands the options that
+are used with the \verb+\newtheorem+ command will work exactly in the same
+manner. {cas-dc.cls} provides three commands to format theorem or
+theorem-like environments: 
+
+\begin{verbatim}
+ \newtheorem{theorem}{Theorem}
+ \newtheorem{lemma}[theorem]{Lemma}
+ \newdefinition{rmk}{Remark}
+ \newproof{pf}{Proof}
+ \newproof{pot}{Proof of Theorem \ref{thm2}}
+\end{verbatim}
+
+
+The \verb+\newtheorem+ command formats a
+theorem in \LaTeX's default style with italicized font, bold font
+for theorem heading and 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. 
+
+\begin{verbatim}
+  \begin{theorem} 
+   For system (8), consensus can be achieved with 
+   $\|T_{\omega z}$ ...
+     \begin{eqnarray}\label{10}
+     ....
+     \end{eqnarray}
+  \end{theorem}
+\end{verbatim}  
+
+
+\newtheorem{theorem}{Theorem}
+
+\begin{theorem}
+For system (8), consensus can be achieved with 
+$\|T_{\omega z}$ ...
+\begin{eqnarray}\label{10}
+....
+\end{eqnarray}
+\end{theorem}
+
+The \verb+\newdefinition+ command is the 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 define counters for the environments defined.
+
+The \verb+\newproof+ command defines proof environments with
+upright font shape.  No counters are defined. 
+
+
+\section[Enumerated ...]{Enumerated and Itemized Lists}
+{cas-dc.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{verbatim}
+ \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 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.
+    \item One more item before we start another.
+    \item One more item before we start another.
+    \item One more item before we start another.
+\end{verbatim}
+
+Further, the enhanced list environment allows one to prefix a
+string like `step' to all the item numbers.  
+
+\begin{verbatim}
+ \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.
+ \end{enumerate}
+\end{verbatim}
+
+\section{Cross-references}
+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:
+\textcolor{blue}{Fig.~1}.  In the same way,
+the words \textcolor{blue}{Ref.~[1]} 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{Bibliography}
+
+Two bibliographic style files (\verb+*.bst+) are provided ---
+{model1-num-names.bst} and {model2-names.bst} --- the first one can be
+used for the numbered scheme. This can also be used for the numbered
+with new options of {natbib.sty}. The second one is for the author year
+scheme. When  you use model2-names.bst, the citation commands will be
+like \verb+\citep+,  \verb+\citet+, \verb+\citealt+ etc. However when
+you use model1-num-names.bst, you may use only \verb+\cite+ command.
+
+\verb+thebibliography+ environment.  Each reference is a\linebreak
+\verb+\bibitem+ and each \verb+\bibitem+ is identified by a label,
+by which it can be cited in the text:
+
+\noindent 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 {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:\break
+\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 the numbered
+scheme.  {natbib} package is loaded by {cas-dc} 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 {natbib}
+package, you can do so with the \verb+\biboptions+ command.  For
+details of various options of the {natbib} package, please take a
+look at the {natbib} documentation, which is part of any standard
+\LaTeX{} installation.
+
+\appendix
+\section{My Appendix}
+Appendix sections are coded under \verb+\appendix+.
+
+\verb+\printcredits+ command is used after appendix sections to list 
+author credit taxonomy contribution roles tagged using \verb+\credit+ 
+in frontmatter.

+\begin{itemize} \item document style \item baselineskip \item front
+matter \item keywords and MSC codes \item theorems, definitions and
+proofs \item lables of enumerations \item citation style and labeling.
+\end{itemize}
+
+This class depends on the following packages
+for its proper functioning:
+
+\begin{enumerate}
+\itemsep=0pt
+\item {natbib.sty} for citation processing;
+\item {geometry.sty} for margin settings;
+\item {fleqn.clo} for left aligned equations;
+\item {graphicx.sty} for graphics inclusion;
+\item {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.
+
+\section{Installation}
+
+The package is available at author resources page at Elsevier
+(\url{http://www.elsevier.com/locate/latex}).
+The class may be moved or copied to a place, usually,
+\verb+$TEXMF/tex/latex/elsevier/+, %$%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+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{Front matter}
+
+The author names and affiliations could be formatted in two ways:
+\begin{enumerate}[(1)]
+\item Group the authors per affiliation.
+\item Use footnotes to indicate the affiliations.
+\end{enumerate}
+See the front matter of this document for examples. 
+You are recommended to conform your choice to the journal you 
+are submitting to.
+
+\section{Bibliography styles}
+
+There are various bibliography styles available. You can select the
+style of your choice in the preamble of this document. These styles are
+Elsevier styles based on standard styles like Harvard and Vancouver.
+Please use Bib\TeX\ to generate your bibliography and include DOIs
+whenever available.
+
+Here are two sample references: 
+See \citet{Fortunato2010}. Also refer \citet{Fortunato2010,NewmanGirvan2004}.
+More citations are here \citep{Fortunato2010,Vehlowetal2013}.
+
+\section{Floats}
+{Figures} may be included using the command, \verb+\includegraphics+ in
+combination with or without its several options to further control
+graphic. \verb+\includegraphics+ is provided by {graphic[s,x].sty}
+which is part of any standard \LaTeX{} distribution.
+{graphicx.sty} is loaded by default. \LaTeX{} accepts figures in
+the postscript format while pdf\LaTeX{} accepts {*.pdf},
+{*.mps} (metapost), {*.jpg} and {*.png} formats. 
+pdf\LaTeX{} does not accept graphic files in the postscript format. 
+
+\begin{figure}
+	\centering
+		\includegraphics[scale=.75]{figs/Fig1.pdf}
+	\caption{The evanescent light - $1S$ quadrupole coupling
+	($g_{1,l}$) scaled to the bulk exciton-photon coupling
+	($g_{1,2}$). The size parameter $kr_{0}$ is denoted as $x$ and
+	the \PMS is placed directly on the cuprous oxide sample ($\delta
+	r=0$, See also Table \protect\ref{tbl1}).}
+	\label{FIG:1}
+\end{figure}
+
+
+The \verb+table+ environment is handy for marking up tabular
+material. If users want to use {multirow.sty},
+{array.sty}, etc., to fine control/enhance the tables, they
+are welcome to load any package of their choice and
+{cas-sc.cls} will work in combination with all loaded
+packages.
+
+\begin{table}[width=.9\linewidth,cols=4,pos=h]
+\caption{This is a test caption. This is a test caption. This is a test
+caption. This is a test caption.}\label{tbl1}
+\begin{tabular*}{\tblwidth}{@{} LLLL@{} }
+\toprule
+Col 1 & Col 2 & Col 3 & Col4\\
+\midrule
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+12345 & 12345 & 123 & 12345 \\
+\bottomrule
+\end{tabular*}
+\end{table}
+
+\section[Theorem and ...]{Theorem and theorem like environments}
+
+{cas-sc.cls} provides a few shortcuts to format theorems and
+theorem-like environments with ease. In all commands the options that
+are used with the \verb+\newtheorem+ command will work exactly in the same
+manner. {cas-sc.cls} provides three commands to format theorem or
+theorem-like environments: 
+
+\begin{verbatim}
+ \newtheorem{theorem}{Theorem}
+ \newtheorem{lemma}[theorem]{Lemma}
+ \newdefinition{rmk}{Remark}
+ \newproof{pf}{Proof}
+ \newproof{pot}{Proof of Theorem \ref{thm2}}
+\end{verbatim}
+
+
+The \verb+\newtheorem+ command formats a
+theorem in \LaTeX's default style with italicized font, bold font
+for theorem heading and 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. 
+
+\begin{verbatim}
+  \begin{theorem} 
+   For system (8), consensus can be achieved with 
+   $\|T_{\omega z}$ ...
+     \begin{eqnarray}\label{10}
+     ....
+     \end{eqnarray}
+  \end{theorem}
+\end{verbatim}  
+
+\newtheorem{theorem}{Theorem}
+
+\begin{theorem}
+For system (8), consensus can be achieved with 
+$\|T_{\omega z}$ ...
+\begin{eqnarray}\label{10}
+....
+\end{eqnarray}
+\end{theorem}
+
+The \verb+\newdefinition+ command is the 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 define counters for the environments defined.
+
+The \verb+\newproof+ command defines proof environments with
+upright font shape.  No counters are defined. 
+
+
+\section[Enumerated ...]{Enumerated and Itemized Lists}
+{cas-sc.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{verbatim}
+ \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 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.
+    \item One more item before we start another.
+    \item One more item before we start another.
+    \item One more item before we start another.
+\end{verbatim}
+
+Further, the enhanced list environment allows one to prefix a
+string like `step' to all the item numbers.  
+
+%\pagebreak
+\begin{verbatim}
+ \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.
+ \end{enumerate}
+\end{verbatim}
+
+\section{Cross-references}
+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:
+\textcolor{blue}{Fig.~1}.  In the same way,
+the words \textcolor{blue}{Ref.~[1]} 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{Bibliography}
+
+Two bibliographic style files (\verb+*.bst+) are provided ---
+{model1-num-names.bst} and {model2-names.bst} --- the first one can be
+used for the numbered scheme. This can also be used for the numbered
+with new options of {natbib.sty}. The second one is for the author year
+scheme. When  you use model2-names.bst, the citation commands will be
+like \verb+\citep+,  \verb+\citet+, \verb+\citealt+ etc. However when
+you use model1-num-names.bst, you may use only \verb+\cite+ command.
+
+\verb+thebibliography+ environment.  Each reference is a
+\verb+\bibitem+ and each \verb+\bibitem+ is identified by a label,
+by which it can be cited in the text:
+
+\noindent 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 {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 the numbered
+scheme.  {natbib} package is loaded by {cas-sc} 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 {natbib}
+package, you can do so with the \verb+\biboptions+ command.  For
+details of various options of the {natbib} package, please take a
+look at the {natbib} documentation, which is part of any standard
+\LaTeX{} installation.
+
+\appendix
+\section{My Appendix}
+Appendix sections are coded under \verb+\appendix+.
+
+\verb+\printcredits+ command is used after appendix sections to list 
+author credit taxonomy contribution roles tagged using \verb+\credit+ 
+in frontmatter.
+

+
+\subsection{Various Marks in the Front Matter}
+
+The front matter becomes complicated due to various kinds
+of notes and marks to the title and author names. Marks in
+the title will be denoted by a star ($\star$) mark;
+footnotes are denoted by super scripted Arabic numerals,
+corresponding author by of an Conformal asterisk (*) mark.
+
+\subsubsection{Title marks}
+
+Title mark can be entered by the command, \verb+\tnotemark[<num>]+
+and the corresponding text can be entered with the command
+\verb+\tnotetext[<num>]+ \verb+{<text>}+. An example will be:
+
+\begin{vquote}
+\title[mode=title]{Leveraging social media news to predict
+                      stock index movement using RNN-boost}
+
+\tnotemark[1,2]
+
+\tnotetext[1]{This document is the results of the research
+   project funded by the National Science Foundation.}
+
+\tnotetext[2]{The second title footnote which is a longer 
+   text matter to fill through the whole text width and 
+   overflow into another line in the footnotes area of 
+   the first page.}
+\end{vquote}
+
+\verb+\tnotetext+ and \verb+\tnotemark+ can be anywhere in
+the front matter, but shall be before \verb+\maketitle+ command.
+
+\subsubsection{Author marks}
+
+Author names can have many kinds of marks and notes:
+
+\begin{vquote}
+    footnote mark : \fnmark[<num>]
+    footnote text : \fntext[<num>]{<text>}
+    affiliation mark : \author[<num>]
+    email : \ead{<emailid>}
+    url : \ead[url]{<url>}
+    corresponding author mark : \cormark[<num>]
+    corresponding author text : \cortext[<num>]{<text>}
+\end{vquote}
+
+\subsubsection{Other marks}
+
+At times, authors want footnotes which leave no marks in
+the author names. The note text shall be listed as part of
+the front matter notes. Class files provides
+\verb+\nonumnote+ for this purpose. The usage
+
+\begin{vquote}
+\nonumnote{<text>}
+\end{vquote}
+
+\noindent and should be entered anywhere before the \verb+\maketitle+
+command for this to take effect. 
+
+\subsection{Abstract and Keywords}
+
+Abstract shall be entered in an environment that starts
+with \verb+\begin{abstract}+ and ends with
+\verb+\end{abstract}+. Longer abstracts spanning more than
+one page is also possible in Class file even in double
+column mode. We need to invoke longmktitle option in the
+class loading line for this to happen smoothly.
+
+The key words are enclosed in a \verb+{keyword}+
+environment.
+
+\begin{vquote}
+\begin{abstract}
+ This is a abstract. \lipsum[3]
+\end{abstract}
+
+\begin{keywords}
+ First keyword \sep Second keyword \sep Third 
+    keyword \sep Fourth keyword
+\end{keywords}
+\end{vquote}
+
+\section{Main Matter}
+\subsection{Tables}
+\subsubsection{Normal tables}
+
+\begin{vquote}
+\begin{table}
+  \caption{This is a test caption.}
+  \begin{tabular*}{\tblwidth}{@{} LLLL@{} }
+   \toprule
+    Col 1 & Col 2\\
+   \midrule

+    12345 & 12345\\
+   \bottomrule
+  \end{tabular*}
+\end{table}

+\subsection{Theorem and theorem like environments}
+
+CAS class file 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. Class file provides three
+commands to format theorem or theorem like environments:
+
+\begin{enumerate}
+\item \verb+\newtheorem+ command formats a theorem in
+\LaTeX's default style with italicized font for theorem
+statement, bold weight for theorem heading and theorem
+number typeset at the right of theorem heading. It also
+optionally accepts an argument which will be printed as an
+extra heading in parentheses. Here is an example coding and
+output:
+
+\begin{vquote}
+\newtheorem{theorem}{Theorem}
+\begin{theorem}\label{thm}
+ The \WGM evanescent field penetration depth into the 
+ cuprous oxide adjacent crystal is much larger than the 
+ \QE radius: 
+ \begin{equation*}
+  \lambda_{1S}/2 \pi \left({\epsilon_{Cu2O}-1}
+    \right)^{1/2} = 414 \mbox{ \AA} \gg a_B = 4.6 
+    \mbox{ \AA}  
+ \end{equation*}
+\end{theorem}
+\end{vquote}
+
+\item \verb+\newdefinition+ command does exactly the same
+thing as with except that the body font is up-shape instead
+of italic. See the example below:
+
+\begin{vquote}
+\newdefinition{definition}{Definition}
+\begin{definition}
+ The bulk and evanescent polaritons in cuprous oxide
+ are formed through the quadrupole part of the light-matter
+ interaction:
+ \begin{equation*}
+  H_{int} = \frac{i e }{m \omega_{1S}} {\bf E}_{i,s} 
+    \cdot {\bf p}
+ \end{equation*}
+\end{definition}
+\end{vquote}
+
+\item \verb+\newproof+ command helps to define proof and
+custom proof environments without counters as provided in
+the example code. Given below is an example of proof of
+theorem kind.
+
+\begin{vquote}
+\newproof{pot}{Proof of Theorem \ref{thm}}
+\begin{pot}
+ The photon part of the polariton trapped inside the \PMS
+ moves as it would move in a micro-cavity of the effective
+ modal volume $V \ll 4 \pi r_{0}^{3} /3$. Consequently, it
+ can escape through the evanescent field. This evanescent
+ field essentially has a quantum origin and is due to
+ tunneling through the potential caused by dielectric
+ mismatch on the \PMS surface. Therefore, we define the
+ \emph{evanescent} polariton (\EP) as an evanescent light -
+ \QE coherent superposition.
+\end{pot}
+\end{vquote}
+
+\end{enumerate}
+
+\subsection{Enumerated and Itemized Lists}
+
+CAS class files 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. You can see the coding and
+typeset copy. 
+
+\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 as in the optional argument.
+  \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.
+  \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.
+\end{vquote}
+
+\begin{vquote}
+      \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}
+
+\section{Biography}
+
+\verb+\bio+ command have the below options:
+\begin{enumerate}
+ \item \verb+width:+ Width of the author photo (default is 1in).
+ \item \verb+pos:+ Position of author photo.
+\end{enumerate}
+
+\begin{vquote}
+\bio[width=10mm,pos=l]{tuglogo.jpg}
+ \textbf{Another Biography:}
+  Recent experimental \cite{HARA:2005} and theoretical
+  \cite{DEYCH:2006} studies have shown that the \WGM can travel
+  along the chain as "heavy photons". Therefore the \WGM 
+  acquires the spatial dispersion, and the evanescent 
+  quadrupole polariton has the form (See Fig.\ref{FIG:3}):
+\endbio

+\section{Bibliography}
+
+For CAS categories, two reference models are recommended.
+They are \file{model1-num-names.bst} and \file{model2-names.bst}.
+Former will format the reference list and their citations according to
+numbered scheme whereas the latter will format according name-date or
+author-year style. Authors are requested to choose any one of these
+according to the journal style. You may download these from 
+
+The above bsts are available in the following location for you to
+download:
+
