How to add citations in style [xx-yy] in LyX?
How to display citations in text grouped as [1-3] in stead of [1,2,3]
Two blue arrows at top right of icons On some icons I am seeing a two blue arrows at the top the right pointing towards each other. I first noticed it on the icons on folders which I archived which happened randomly. I archived the folder and the text went blue as expected, then when I went to the folder again the text was black and the folder icon has these arrows. When I just recently installed Office 2007, I noticed the same arrows on the icons for the programs. OS: Windows 10 Pro 64-bit (the latest update: 1115) Application: Microsoft Office 2007 suite and file explorer Is it possible to assign numbers generated in an Error-Message? When does Thread.CurrentThread.Join() make sense? I'm in the market for a new Smartphone. Except for iPhone's, I'm new in the field and probably have some misconceptions.  My first choice was the Google Nexus S, but I was offered a great deal on the Samsung S Galaxy II (i9100). The only issue is that I read that it came with an "enhanced" version of Android. Being familiar with PC's, I know that these enhancements are almost always bloatware: I always do a clean install of Windows to get rid of it.  My question is fairly simple: is this possible to use the stock Google Android OS on the Samsung S Galaxy II (i9100)? That was the killer feature of the Nexus S for me: coming directly from Google, easily upgradable. Would that be possible and if yes, how?  Thank you for enlightening me. Forgotten iOS Restrictions Password/Passcode Cannot move file to trash warning when trying to delete a file in Nautilus I am trying to delete files in Nautilus and every time I try to delete one it always gives me this message:     Cannot move file to trash, do you want to delete immediately?   Then it gives me several questions. All I want is that when I press Delete in the keyboard, it sends it automatically to the trash can. Not to ask me every time.  The problem relates to NTFS partitions, external drives but also include Linux filesystems.  What are the reasons for nautilus beeing not able to move to trash? If $2^p-1$ is a prime, (thus $p$ is a prime, too) then $p\mid 2^p-2=\phi(2^p-1).$  But I find $n\mid \phi(2^n-1)$ is always hold, no matter what $n$ is. Such as $4\mid \phi(2^4-1)=8.$  If we denote $a_n=\dfrac{\phi(2^n-1)}{n}$, then $a_n$ is , but how to prove it is always integer?  Thanks in advance! Is there a deb package to install Firefox ESR?

The characteristic and minimal polynomial of a companion matrix of a monic polynomial $f \in \mathbb F\left[x\right]$ in $1$ variable $x$ over a field $\mathbb F$ plays an important role in understanding the structure of finite dimensional $\mathbb F[x]$-modules.  It is an important fact that the characteristic polynomial and the minimal polynomial of $C(f)$ are both equal to $f$. This can be seen quite easily by induction on the degree of $f$.  Does anyone know a different proof of this fact? I would love to see a graph theoretic proof or a non inductive algebraic proof, but I would be happy with anything that makes it seem like more than a coincidence! Apple Loops Copyright How do you clear a stringstream variable? I've tried several things already,  std::stringstream m; m.empty(); m.clear();   both of which don't work. Minimum safe spacing between lava and flamable materials? It seems that containing lava in solid glass, stone and iron blocks may not be sufficient to prevent wool from burning, even if the lava is completely encased.         After some delay, it seems that fire will jump onto the wool above the iron.   Are solid blocks more effective than airspace, or not? If so, Does it matter whether the corner block is filled in? What are the exact rules on distance that I need, and how can I prevent flammable blocks from being eliminated by nearby lava? Bonus: Does a flowing lava block behave differently than a lava source block when it comes to fire creation? Why is my attempt at downloading Big Sur failing? I am currently using a MacBook Pro 13&quot; Mid 2018 with Touch Bar. Today macOS Big Sur was released and I tried to download it but it's getting stuck at 484.4 MB. Initially, it shows 16-17 minutes left, but as soon as it reaches 484.4 MB it's stuck and the timer goes till 10 hours! My Wi-Fi is totally stable with a speed of 100 Mbps. I tried to restart my Mac but it still gets stuck. Earlier there were similar issues in the App Store (even now they are). The issue was I was not able to download an app unless I connect to the US VPN. I even contacted support but they were not able to help out. It wasn't a big deal as a VPN could be used. But now even with VPN, it gets stuck. Proving that $G$ is a group if $a*x=b$ and $y*a=b$ have solutions. Makeindex error when ! used in \index in align environment See MWE below. The symbol ! in the \index causes an error. This is only the case in align environments (not in equation). So it seems to have to do something with amsmath. If ! is put in an \mbox there is no error. But then of course the font size is not adjusted to subindices. Curiously enough, \index{$C_{K!!}$} (two exclamation marks) doesn't cause any error.    \documentclass{article} \usepackage{amsmath} \usepackage{imakeidx} \makeindex \begin{document} \begin{align} y\index{$C_{K!}$} \end{align} \printindex \end{document}     Any solutions suggested? I have a file with ANSI colors.  test.txt: \e[0;31mExample\e[0m  I would like to display the content of this file in a terminal, like cat does, but I would like to display the colors as well.
