 \section{模板介绍}
 
-此模板是基于 \LaTeX{} 的标准文档类设计，也即意味着你可以在在文类选项使用文档（article）类型的选项，比如 \lstinline{a4paper, 12pt} 等等。本模板支持 \lstinline{PDFLaTeX} 和 \lstinline{XeLaTeX} 两种编译方式。
+此模板是基于 \LaTeX{} 的标准文类 article设计，也即意味着你可以把 article 文类的选项传递给本模板，比如 \lstinline{a4paper, 10pt} 等等（推荐使用 \lstinline{11pt}）。本模板支持 \lstinline{PDFLaTeX} 和 \lstinline{XeLaTeX}\footnote{中文字体均使用 \lstinline{ctex} 包设置。} 两种编译方式。
+
+数学字体的效果如下：
+
+\begin{equation}
+(a+3b)^{n} = \sum_{k=0}^{n} C_{n}^{k} a^{n-k} (3b)^k\label{eq:binom}
+\end{equation}
       
 \subsection{全局选项}
 我在这个模板中定义了一个语言选项 \lstinline{lang}，可以选择英文模式 \lstinline{lang=en}（默认）或者中文模式 \lstinline{lang=cn}。当选择中文模式时，图表的标题引导词以及参考文献，定理引导词等信息会变成中文。你可以通过下面两种方式来选择语言模式：
-\begin{lstlisting}
-\documentclass[lang=cn]{elegantpaper}
-\documentclass{cn}{elegantpaper} % 两者皆可
-\end{lstlisting}
-
-\subsection{字体设置}
-\subsubsection[选择 PDFLaTeX 编译]{选择 \lstinline{PDFLaTeX} 编译}
-如果你使用 \lstinline{PDFLaTeX} 编译，默认的 Computer Modern 字体被换成了 \lstinline{newtx} 系列字体，默认的字体字号是 11 pt。关于字体设置的宏包主要用到了：
-\begin{itemize}
-	\item \lstinline{newtxtext} 用于文档正文字体，类似于 Times New Roman 字体。
-	\item \lstinline{newtxmath} 用于数学字体，搭配 \lstinline{newtx} 非常合适，类似于过时的 \lstinline{times} 宏包的效果。
-	\item \lstinline{FiraMono} 用于打字机字体，并使用了 \lstinline{scale=0.7} 选项。
-	\item \lstinline{ctex} 用于中文字体设置，并使用了 \lstinline{scheme=plain} 选项。
-\end{itemize}
-
-\subsubsection[选择 XeLaTeX 编译]{选择 \lstinline{XeLaTeX} 编译}
-如果你选择 \lstinline{XeLaTeX} 编译的话，那么设置字体的宏包为 \lstinline{fontspec} 和 \lstinline{xeCJK}。由于模板中使用的字体是 Windows 中的字体，所以如果你使用其他操作系统，比如 Linux 或者 Mac OS，那么你需要把所用字体替换为你系统中的字体。设置字体的命令：
 
 \begin{lstlisting}
-\RequirePackage{fontenc}
-\RequirePackage[no-math]{fontspec}
-\setmainfont{Times New Roman}[NFSSFamily=ntxtlf]
-\setsansfont{Arial}
-%\setmonofont[Scale=0.7]{Courier New}

-\setCJKmonofont[BoldFont={SimHei},ItalicFont={KaiTi},Scale=0.7]{Microsoft YaHei}
-\XeTeXlinebreaklocale "zh"
-\XeTeXlinebreakskip = 0pt plus 1pt minus 0.1pt
-\RequirePackage{newtxmath}
+\documentclass[lang=cn]{elegantpaper} % or
+\documentclass{cn}{elegantpaper} 
 \end{lstlisting}
 
-\subsubsection{其他设置}
-
-这几个包由于都是一个系列的，字体搭配起来非常合适，字体宽度非常契合！唯独数学字体中的大型运算符，比如求和符号和积分符号不是很好看，为此，我把它们又改回了原先的字体效果。公式~(\ref{eq:binom}) 展示了最终的数学字体的效果。
-\begin{equation}
-(a+3b)^{n} = \sum_{k=0}^{n} C_{n}^{k} a^{n-k} (3b)^k \label{eq:binom}
-\end{equation}
-
-我把行距设定为 1.3，并且使用了 \lstinline{microtype} 宏包调整字体的间距，为了去除字体字号，字形警告信息，我使用了 \lstinline{type1cm} 宏包。

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Peer-to-peer (P2P) lending, as a novel economic lending model, has triggered new challenges on making effective investment decisions. In a P2P lending platform, one lender can invest N loans and a loan may be accepted by M investors, thus forming a bipartite graph. Basing on the bipartite graph model, we built an iteration computation model to evaluate the unknown loans. To validate the proposed model, we perform extensive experiments on real-world data from the largest American P2P lending marketplace - Prosper. By comparing our experimental results with those obtained by Bayes and Logistic Regression, we show that our computation model can help borrowers select good loans and help lenders make good investment decisions. Experimental results also show that the Logistic classification model is a good complement to our iterative computation model, which motivates us to integrate the two classification models. The experimental results of the hybrid classification model demonstrate that the logistic classification model and our iteration computation model are complementary to each other. We conclude that the hybrid model (i.e., the integration of iterative computation model and Logistic classification model) is more efficient and stable than the individual model alone.},

-abstract = {Would consumer surplus increase if annuity rates were age-neutral? This paper characterizes the socially optimal contractibility of a given signal in markets with adverse selection. A signal (e.g., age) partitions consumers into subsets (e.g., young and old). A regulator restricts price-discrimination on the basis of the signal if the consumer subsets where the level of cost is higher are also the subsets where there is greater deadweight loss due to adverse selection. Such signals are empirically common. To illustrate the welfare benefit of price discrimination policy, I use a structural model to estimate its impact on the UK annuities market. The model is estimated using proprietary data that include the annuity seller's estimate of each individual's longevity. I find that restricting price discrimination can increase consumer surplus by the equivalent of about {\pounds}6.5 million per year.},

Controlling for variables of investor demographics, investor experience, and loan characteristics, we find that loans invested by female investors are more likely to default and have lower loan return in the future than loans invested by male investors. We define abnormal default or abnormal loan return as the part of the loan default or the part of loan return that is not explained by loan characteristics and find that the loans invested by female investors have higher abnormal default and lower abnormal loan return than the loans invested by male investors. Furthermore, female investors perform similarly to male investors in abnormal default or abnormal loan return when investors have high levels of education or income or when investors work in finance or information technology industries.},

-abstract = {The objective of our paper is to explore the role of P2P lending platforms through the prism of the theory of financial intermediation. P2P lending platforms perform the brokerage function of financial intermediaries by matching lenders' supply and borrowers' demand of funding, according to the risk and the maturity of their needs. Unlike banks, P2P lending platforms do not create money and do not perform risk and maturity transformation. However, they can organize secondary markets to trade loan contracts before maturity and some P2P lending platforms aim at providing a fixed income to lenders. To ensure efficient and sustainable financial intermediation, P2P lending platforms need to ensure that they are not subject to principal-agent problems and that their incentives coincide with those of lenders. The possibility of orderly resolution of P2P lending platforms failures might decrease moral hazard problems that are inherent in the modern financial intermediation.},
