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, \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{
