I'm trying to write some substances with dopants in them, e. g. ”InO2:Sn.“ Although I could split up the formula every time it contained a dopant, this wasn't really smart to do and I'd also get in trouble with line endings/non-breaking spaces at some point. How to bring a colon (:) into \ce{}? MWE \documentclass{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{siunitx} \usepackage[version=4]{mhchem} \begin{document}     \ce{InO2}:\ce{Sn}     %\ce{InO2:Sn} \end{document}
Usually I use the package mhchem for writing chemical formulas, but until now I was not able to find a solution for writing crystals such as Nd^{3+}:YAG properly with this package. When simply writing   \ce{Nd^{3+}:YAG}   it results in an error. My current alternative solution is to write it as   \ce{Nd^{3+}}:\ce{YAG}   Is there a more elegant way to do that?
how to prevent cell color to cover table's borders? When I change the background color of a cell in a table, the color covers the borders, however I want the horizontal lines to remain.  I have a simple command \cellcolor[gray]{0.9} in my table. Can anybody help me with this problem? Running Windows 7  I'm trying to boost the startup speed of my computer and I'm going through "msconfig" and "services.msc" to disable some applications from starting up automatically when the computer turns on.  There are some good sites that document the entries found in the "Processes" tab of the task manager.  You can find out if they are safe to kill, who the manufacturer is, and what the process in question is used  for.  Are there any sites that list startup processes &amp;| services that are safe to kill?  For example, there is an entry in msconfig that just says "Computer Browser" - pretty vague, but seems like something to not kill.  On the other hand, there is an entry in msconfig that says "Extensible Authentication Protocol" - pretty specific and seems like it shouldn't be killed, but how can I know for sure?  Does anyone know if there are any websites documenting the "killable" items listed in both msconfig &amp; services.msc? Every time I render an image and try to save it, it just disappears. How do you exactly save a render? I am using a mac. I am not a administrator and I would like to find the administrator password. I would not like to reset it however. Is there anyway to find and not reset the administrator password? What is the mysterious stranger doing in my vault? Objective-C: Use singleton vs. use class as an object? I want to work on a small app that will use Telegram from within Ubuntu but wanted to first know if there was already a work in progress for this since I noticed that, for example, pidgin has support for WhatsApp. With this in mind, is there a messenger app that has support (even basic support) for Telegram from within Ubuntu. Short story collection about Transporter "Doors" I'm looking for a short story collection about different uses/inventions of transporter doors. I think it was just a single author collection, that I read in the early 2000s.  In each story these Transporter Doors exist, I seem to remember them being described as blank grey sheets. You step through them and come out somewhere else. The forward to the book talked about early Rocket stories where the launch of a spaceship would be the end of the tale.  Plots of the individual stories:  Two men one of whom's home is inside an asteroid are discussing the use of Base12 in their society and if it is because they have 12 fingers, one says that "people" used to use base10. The implication is that a different species arrived through the doors and replaced humans.  A man puts the code for his home into a door and is instead transported to prison where he's accused of murdering his wife, which he strongly denies.   Two scientists and a pilot take a probe ship deep into Jupiter's atmosphere, the will return to base via a door that they need to construct while they are down there. The scientists dislike each other and don't work well together. When they finish the door, the hamsters seem woosy out the other side, but the scientists insist it is ready. The pilot says he will go first as he can't fix it if it's wrong. When he arrives on the far side he's mentally damaged and the scientists have to get along without him acting as a buffer while the try to save themselves. Differential equation with resonance Installing PHP 5.3 in Ubuntu 14.04 I've just installed Ubuntu 14.04 and am trying to install php 5.3. But when I run   apt-get install php5    it's installing php 5.5.9-1ubuntu4. I need to use php 5.3 in the system because the application I'm working on is built with php 5.3.   How can I achieve this? When should I use \input vs. \include? Block apps from accessing the Internet on Android device In Android, is it possible to block apps from accessing the Internet? Many apps will often connect to remote servers in the background, including Google's own apps or system services. Over time this can eat away at a user's data limit set by a mobile carrier. Does Android allow an app to act as a firewall whereby the user can select which apps have access to the Internet? Or does the device have to be rooted to have that ability? There are Recurrent Neural Networks and Recursive Neural Networks. Both are usually denoted by the same acronym: RNN. According to , Recurrent NN are in fact Recursive NN, but I don't really understand the explanation.  Moreover, I don't seem to find which is better (with examples or so) for Natural Language Processing. The fact is that, although Socher uses Recursive NN for NLP in his , I can't find a good implementation of recursive neural networks, and when I search in Google, most of the answers are about Recurrent NN.  Besides that, is there another DNN which applies better for NLP, or it depends on the NLP task? Deep Belief Nets or Stacked Autoencoders? (I don't seem to find any particular util for ConvNets in NLP, and most of the implementations are with machine vision in mind).  Finally, I would really prefer DNN implementations for C++ (better yet if it has GPU support) or Scala (better if it has Spark support) rather than Python or Matlab/Octave.  I've tried Deeplearning4j, but it's under constant development and the documentation is a little outdated and I can't seem to make it work. Too bad because it has the "black box" like way of doing things, very much like scikit-learn or Weka, which is what I really want. Why can't I import "pygtk" with Python 3.2 from PyDev? Establishing a Basis for $F[x]/(f(x))$ Hypothesis:   $f(x) = a_0 + a_1 x + \ldots + a_n x^n \in F[x]$ s.t. $f(x)$ irreducible over field $F$. $deg(f(x)) = n \ge 1$. Let $V = (f(x)) \subset F[x]$.   Goal: Show that $\mathcal{B} = \{1 + V, x + V, x^2 + V, \ldots , x^{n-1} + V\}$ forms a basis for $E = F[x]/V$  Attempt:   Linear Independence: If this set weren't linearly independent, then a non-trivial $b_i \in F$ would satisfy  $$ b_0 + b_1x + \ldots + b_{n-1} x^{n-1} + V = 0 + V $$   But this would then imply that $b_0 + b_1x + \ldots + b_{n-1} x^{n-1}  \in 0 + V$. But this would contradict $V = (f(x))$ since it is impossible that $f(x)\,\,|\,\,b_0 + b_1x + \ldots + b_{n-1} x^{n-1}$ of strictly lower degree.  Now how would I show that this set spans $F[x]/V$? How can I remove a suggestion from the Chrome address bar? I've got a couple of URL autocomplete suggestions where Chrome suggests the wrong URL consistently.   How can I delete the incorrect entry from the address bar's suggestion list? The page I want shows up too but it's never the first result. Ways to get free and legal access to research papers as a researcher I’ve discovered that website like ResearchGate offer the possibility to ask the paper editor to provide his paper for free. Many are collaborating.  Are there any other ways for researchers to obtain free access to papers? Inequality ${n \choose k} \leq \left(\frac{en}{ k}\right)^k$ The probability of two dice summing to k is simple enough, make a diagram of the throws,  $$ \begin{array}{c}  &amp;|&amp;1&amp;2&amp;3&amp;4&amp;5&amp;6\\\hline 1&amp;|&amp;2&amp;3&amp;4&amp;5&amp;6&amp;7\\ 2&amp;|&amp;3&amp;4&amp;5&amp;6&amp;7&amp;8\\ 3&amp;|&amp;4&amp;5&amp;6&amp;7&amp;8&amp;9\\ 4&amp;|&amp;5&amp;6&amp;7&amp;8&amp;9&amp;\color{green}{10}\\ 5&amp;|&amp;6&amp;7&amp;8&amp;9&amp;\color{green}{10}&amp;11\\ 6&amp;|&amp;7&amp;8&amp;9&amp;\color{green}{10}&amp;11&amp;12\\ \end{array} $$  and the probability of a sum is just the length of the corresponding diagonal divided by $36$. For instance, $\mathrm{P}(\mathrm{sum} = 10) = \frac{3}{36} = \frac{1}{12}$. However, it's not as easy to draw a diagram for three dice or more, so how would a general formula look? Where do the regions of Westeros appear to align as of the season 6 finale? Based on , my understanding is that there are 9 regions of Westeros subject to the rule of the Iron Throne, from Dorne joining up to Cersei killing Robert.  With whom does [insert region] align in what appears to be Daenerys vs Cersei?   Kingdom of the North -- Daenerys probably but currently busy with White Walkers Kingdom of the Mountain and the Vale -- Daenerys probably but currently busy with White Walkers (supposedly; depends on what Littlefinger has in mind) Kingdom of the Isles and Rivers (Iron Islands) -- Daenerys Kingdom of the Isles and Rivers (Riverlands) -- Cersei because the Freys are with the Lannisters? Kingdom of the Rock -- Cersei because she is a Lannister Kingdom of the Stormlands -- Cersei? Kingdom of the Reach -- Daenerys after invitation of Varys and Ellaria Principality of Dorne -- Daenerys after invitation of Varys presumably Crownlands -- Cersei since Cersei is currently occupying the Iron Throne   Am I understanding this right? Anything wrong?
