So, there's this picture   Floating around on the internet for the standard model of physics in a relatively short form. I want to typeset this in LaTeX in order to print it. However, I can't find a way to typeset the crossed out D in the second line.  So far, I have this      \documentclass[a4paper,10pt]{scrartcl}       \usepackage{amsmath,amssymb}      \begin{document}     What part of      \begin{align*}     \mathcal{L} &amp;= - \frac{1}{4} F_{\mu \nu} F^{\mu \nu} \\         &amp;+ i \bar{\psi} D \psi + h.c. \\         &amp;+ \bar{\psi}_i y_{ij} \psi_j \phi + h.c. \\         &amp;+ |D_\mu \phi|^2 - V(\phi)     \end{align*}      didn't you understand?      \end{document}
How can I strike through an expression (e.g. "2x") obliquely, e.g. from bottom left to top right, so as to indicate cancellation? With the \sout command from the ulem package, I can only strike horizontally.
What I'm trying to understand is, to what degree does the status/rank of the University (where one completes his/her Ph.D) matter while shaping his/her career after graduation? I would like to know the weight given to one's school in both the following cases:   While applying for post-docs/faculty positions in academia While applying to industrial research labs   For instance, I've read on some forums (I can't locate the link now) that while considering prospective applications for tenure-track faculty positions, very few Universities accept a candidate who has completed his/her Ph.D from a lower ranked school having a lesser "brand" value, irrespective of the fact whether he/she has published equally original work as his/her counterpart from an Ivy league college. How much truth is in this statement? It would be really great if someone already in academia, either as a newly-accepted faculty or someone on the Faculty Hiring committee could share their experiences/statistics on this regard. I'm simply interested to know the answer, without commenting at all on whether such a practice is justifiable.  Similarly, what about recruitment to internationally acclaimed research labs (like  or ) - what importance do they place on the pedigree of a candidate's college, before taking into consideration what they published ?  I'm personally interested in answers related to the field of Computer Science (theory), but the question is applicable to any prospective grad student in any discipline in my opinion. Feel free to share your personal experiences post-Ph.D in detail, as that would give me (and future viewers of this question) about what its like to carve a career once you are out of school!

Edge won't connect to internet, Skype for business won't screen-share, Windows Store won't update apps after Windows 10 version 1809 installed I ran into a problem after upgrading Windows 10 October 2018 to version 1809. After the Windows update I noticed the following problems with Microsoft applications:   Microsoft Edge could no longer connect to the internet even though Chrome, Firefox and IE 11 still could. Skype for Business (formerly Lync) no longer allowed me to share my screen or view another person's shared screen. The Windows Store could not connect to the internet to update apps. The Microsoft Feedback portal could no longer connect to the internet.   How can I resolve these network issues that seemed to cooincide with an upgrade to Win10 ver 1809? How to only append to clipboard (but not overwrite current data)? I have a rather large file, I need to copy the entire contents somewhere, but when I scroll down the page all the data I have selected becomes unselected. I could just copy and paste block by block, but I would find it much easier as there is a lot of data, to just be able to append the contents to the end of the current clipboard data. Is that possible?  That is so that I can have a keyboard shortcut which will enable me to copy this to the clipboard:  I am some nice new text.   When this is what is already there:  I am the old text.   And have it look like this when pasted:  I am the old text. I am some nice new text.   So there are 3 things that I would really like from this (I would have 3 separate keyboard shortcuts to do this):   Append the data to the end of the clipboard and have it put in a RETURN before it (as shown in the example above). Append the data to the end of the clipboard but have it so that there is not RETURN before it so that it would continue on on the same line initially. Have all this but so that the data is put at the beginning of the clipboard before all the data which is currently there.   I am running Ubuntu GNOME 16.04 with GNOME 3.20.

I am using the QGIS expression builder for the label properties of my data.  Is it possible to put different parts of the label in different coordinates on the map?

I've just started using matlab-prettifier.    Since the line \begin{lstlisting}[style=Matlab-editor] is a lot to type, I created my own environment:  \newenvironment{myMP}      {\begin{samepage}\begin{lstlisting}[style=Matlab-editor]}      {\end{lstlisting}\end{samepage}}   I've used this syntax many times before, but in this case it doesn't work.  Is there any reason why I can't enclose the lstlisting inside my own one?  Here's sample code, illustrating the problem.  \documentclass{minimal} \usepackage[framed]{matlab-prettifier}%For matlab code \newenvironment{myMP}      {\begin{samepage} \begin{lstlisting}[style=Matlab-editor]}      {\end{lstlisting} \end{samepage}} \begin{document} \begin{myMP} matlab word \end{myMP} \end{document}   When I run this with pdflatex it returns a *, indicating that the environment wasn't closed properly.  Thanks! Sorry for asking such a basic question - but is there an actual term for the numbers that appear before and after the decimal point?  Example:  25.18  I know the 1 is in the tenths position, the 8 is in the hundredths position. are there singular terms which apply to all of the numbers that appear both before and after the decimal point?  I'm building a billing system, storing dollars and cents as integers (in separate columns), but for other currencies "dollars" and "cents" are not the correct terms = ).  Thanks! Embedded Prolog Interpreter/Compiler for Java I am currently in the process of learning how to prove statements by induction. For the most part, I understand but I am at most clueless when it comes to prove some inequalities.  For example, I am having a hard time proving that: $n &lt; 2^n$ is true. (Even if it's clear that it is indeed true!)  In the induction step, I am stuck with: $n + 1 &lt; 2^{n + 1}$  I don't know what would be the assumption I should make from this statement.  Anyone could point me in the right direction? Thanks! Details on how the Yearling badge works Jawa asked me this  and I didn't know the answer. So I present it to the meta SO community:     [To get the Yearling badge] Do you need to earn the 200 rep within that one year or is it enough to get 200 at some point after being a member for a year? And does 'a year' mean the very first 12 months or the last (sliding window of) 12 months?    I would assume that if you hit 200 reputation after you've already been around for a year, then you would get the Yearling badge. But I don't know. Where such a term would reference the location/time of an object, almost like it was of a property of the object. That is to say, if a duck is red, blue, yellow etc, we describe it has having a certain colour. If it's a nanometre, or 10km big, then it's property of size.  Now I know that where/when an object exists an object isn't a property of an object, but it is something unique to that object, so I think it would be useful to have a shorthand for 'geographical location', and 'time of existence'.  There are terms describing both time and location, such an event, or rendezvous (which I think is used to describe the when and where of a meeting between two humans) but I wan't a term that just describes one of each. KDB: apply dyadic function across two lists Plotting a function with an argument in degrees I want to plot a function. The function is, F is proportional to x/cos(x). Here x is rotation in degree and F is the force. I have to plot the graph where the x axis will be from 0 to 70 degree and the y axis will be linear value 0 to 5. I am not able to find any option to draw graphs where x axis is with rotational degree. Find angle UFO in the picture attached I sent this problem to Presh Talwalkar who suggested me to send it to this site. I tried many things but was not able to find the correct solution.   I made various segments trying to get an equilateral triangle similar to the Russian triangle problem, but no success.  I also tried to flip the triangle UFO over side NO but again no success.   I tried to find like triangles, but not enough.  Could you please give me a hint?   Thanks, R. de Souza How to use java.util.Scanner to correctly read user input from System.in and act on it?
