We can insert a tilde (sometimes called “twiddle”) in a LaTeX document by using \sim where sim refers to similar. When we would like to insert a tilde symbol on top of character(s), we can use \tilde{} instead.
\documentclass{article}
\begin{document}
The model contains $\sim3M$ parameters.
$\tilde{x}$ refers to the parameter of xxx.
\end{document}
Double-blind review is a reviewing process in academic conferences or journals for submitted papers where the ideintities of authors and reviewers should remain anonymous for each other. An alternative adopted instead of the double-blind review is single-blind review where the reviewers know the authors but the reviewers' identities remain anonymous for authors.
One of the most important thing for double-blind reiview is that, as an author, you should not reveal your identities in any manner, e.g., using "in our previous work [1]" in the Related Work or including your source code or dataset link with a URL might contain your identity information (e.g., link to your shared Drive with some of your information can be disclosed).
An interesting solution discovered recently is adding the link http://www.omitted.link/ for the reviewing process and simply replace the link later with actual link. For example, in the latex of your article:
\footnote{\url{http://www.omitted.link/}}
Specifically, the link will point to a dummy page with the following information:

One thing was not convinient when preparing slides for classroom or academic presentation is inserting equations if you are used to LaTex. Recently, I found that the equation feature in the latest Office is improved with the functionality of adding an equation with LaTex syntax, which can be achieved with the following steps:
1. Click the Insert option
2. Click the Equation, which will let you insert equations
3. Now you can write down the equation in LaTex syntax
4. Finally, click $e^x$ Professional highlighed below, then your writen equation in LaTex will be converted to the right format of equation in the slide
It is common when we inserting figures in the papers in LaTex where some of them can have a white border taking up a lot of space. The trim option in \includegraphics aims to crop the figures inside the LaTex environment, which makes manipulating figures easy. For example,
\begin{figure}[!bh]
\centering
\includegraphics[width=.8\linewidth,
trim=0cm 0cm 0cm .4cm, clip=true]
{images/user_difference.pdf}
\caption{The relationship between the number of favorites and retweets for two different users in a log scale.}
\label{fig:user_diff}
\end{figure}
Sometimes when we are writing articles with LaTex, thicker or thiner lines in the tables provide good and clear view on those tables. For instance, the one from the paper "aschern at SemEval-2020 Task 11: It Takes Three to Tango: RoBERTa, CRF, and Transfer Learning" at SemEval 2020 in the below, where the top and bottom lines are thicker than the middle line.
