\section{Introduction}
Thanks for using Overleaf to write your article. Your introduction goes here! Some examples of commonly used commands and features are listed below, to help you get started.
\section{Material and Methods}
Guidelines can be included for standard research article sections, such as this one.
\subsection{Primary Publication}

\subsection{Some \LaTeX{} Examples}
\label{sec:examples}
Use section and subsection commands to organize your document. \LaTeX{} handles all the formatting and numbering automatically. Use \verb|\autoref| and \verb|\label| commands for cross-references, e.g.~\autoref{sec:examples}, \autoref{eq:sum}, \autoref{fig:view}, \autoref{tab:widgets}. You can still use the more common \verb|\ref|, but this will only generate the (sub)section/table/figure/equation number: \ref{tab:withnotes}.
\subsection{Figures and Tables}
Use the table and tabular commands for basic tables --- see \autoref{tab:widgets}, for example. \autoref{tab:withnotes} shows a larger example with \emph{table notes}. You can upload a figure (JPEG, PNG or PDF) using the project menu. To include it in your document, use the \verb|\includegraphics| command as in the code for \autoref{fig:view} below. Captions are always justified and start from the left; don't try to change the alignment.
If you prefer, you can place all your image files in a folder. Remember to include the folder path in your \verb|\includegraphics| command, or use `\verb|\graphicspath|` to specify the path to the folder in which all your image files can be found.
\begin{figure}[ht]\centering
\includegraphics[width=0.5\linewidth]{frog}
\caption{An example image of a frog.}
\label{fig:view}
\end{figure}
\begin{table}[ht]\centering
\caption{An example table.}\label{tab:widgets}
\begin{tabular}{l r}
\toprule
Item & Quantity \\\midrule
Candles & 4 \\
Fork handles & ?\\
\bottomrule
\end{tabular}
\end{table}
\begin{table}[hbt!]\centering
\begin{threeparttable}
\caption{An example table with tablenotes}\label{tab:withnotes}
\begin{tabular}{lccrr}
\toprule
Variables & JKL ($n=30$) & Control ($n=40$) & MN & $t$ (68)\\
\midrule
Age at testing & 38 & 58\tnote{1} & 504.48 & 58 ms\\
Age at testing & 38 & 58 & 504.48 & 58 ms\\
Age at testing & 38 & 58 & 504.48 & 58 ms\\

Age at testing & 38 & 58 & 504.48 & 58 ms\\
\bottomrule
\end{tabular}
\begin{tablenotes}
\item[1] JKL, just keep laughing.
\item[2] MN, merry noise.
\end{tablenotes}
\end{threeparttable}
\end{table}
\subsection{Citations}
LaTeX formats citations and references automatically using the bibliography records in your .bib file, which you can edit via the project menu. Use the \verb|\citet| command for a text citation, like \citet{lees2010theoretical}, and the \verb|\citep| command for a citation in parentheses \citep{McQuilton01012012}.\cite{Bloss029983}
\subsection{Mathematics}
\LaTeX{} is great at typesetting mathematics. Let $X_1, X_2, \ldots, X_n$ be a sequence of independent and identically distributed random variables with $\text{E}[X_i] = \mu$ and $\text{Var}[X_i] = \sigma^2 < \infty$, and let
\begin{equation}\label{eq:sum}
S_n = \frac{X_1 + X_2 + \cdots + X_n}{n}
= \frac{1}{n}\sum_{i}^{n} X_i
\end{equation}
denote their mean. Then as $n$ approaches infinity, the random variables $\sqrt{n}(S_n - \mu)$ converge in distribution to a normal $\mathcal{N}(0, \sigma^2)$.
\subsection{Lists}
You can make lists with automatic numbering \dots
\begin{enumerate}[noitemsep]
\item Like this,
\item and like this.
\end{enumerate}
\dots or bullet points \dots
\begin{itemize}[noitemsep]
\item Like this,
\item and like this.
\end{itemize}
\dots or with words and descriptions \dots
\begin{description}
\item[Word] Definition
\item[Concept] Explanation
\item[Idea] Text
\end{description}
