Xosen

When a post is published or updated, this plugin will send a backup email to the administrator of the WordPress 
blog with an attachment file that contains the post in XML format. The XML follows the format used when WordPress 
exports blog contents so that it can be easily used to restore the post.
The general idea of this plugin is to never loose any of your posts. If you have scheduled a backup of your 
blog once a week, its possible that you will loose the new posts published during that last week. With this 
plugin you will have a backup of all your new published posts in your email account.

Put your plain text <a href="https://www.biophysicslab.com/wp-content/plugins/wpmathpub/phpmathpublisher/doc/help.html" rel="nofollow ugc">mathematical expressions</a> between [pmath size=xx]…[/pmath] shortcode tags. Useful xx-size integer values range from 8 to 24 (default is 12).

<h3>How To</h3>
To toggle to the math mode within your blog’s content, you must use the [pmath size=xx]…[/pmath] markdown tag. The plugin automatically replaces your math text commands into HTML image tags that look sort of like this: 
<img src=”MathFileName.png” style=”vertical-align:-xxpx; display: inline-block ;” alt=”your math text command” title=”your math text command”/>.
Use the shortcode block to enter math equations from the Gutenberg WordPress block editor.
The math commands must be separated by a space character or surrounded by {}.
Examples:
<ul>
<li>[pmath size=12]S(f)(t)=a_{0}+sum{n=1}{+infty}{a_{n} cos(n omega t)+b_{n} sin(n omega t)}[/pmath] </li>
<li>[pmath size=24]delim{lbrace}{matrix{3}{1}{{3x-5y+z=0} {sqrt{2}x-7y+8z=0} {x-8y+9z=0}}}{ }[/pmath] </li>
<li>[pmath]delim{|}{{1/N} sum{n=1}{N}{gamma(u_n)} – 1/{2 pi} int{0}{2 pi}{gamma(t) dt}}{|} le epsilon/3[/pmath]</li>
<li>[pmath size=16]vec{Del}f(x,y) ~ = ~ {partial{f}}/{partial{x}}hat{i} ~ + ~ {partial{f}}/{partial{y}} hat{j}[/pmath]</li>
<li>[pmath size=16]{Del}f(x,y) ~ = ~ {partial{f}}/{partial{x}}i ~ + ~ {partial{f}}/{partial{y}} j[/pmath]</li>
</ul>
