I am using Texmaker for my paper and I encounter a problem here and hope somebody can help me.    As you can see here, the titles are some in Italics and some are not. What cause this anyway? I don't use cite btw, only footnote.  \begin{thebibliography}{99}  \bibitem[Monopolkommision (1988)]{monopol1988} Monopolkommision (1988): \em{Siebentes Hauptgutachten der Monopolkommission 1986/1987}, In: Deutscher Bundestag Online, 19.07.1988 (http://dipbt.bundestag.de/doc/btd/11/026/1102677.pdf vom 16.08.2016). \bibitem[Monopolkommision (1992)]{monopol1992} Monopolkommision (1992): \em{Neuntes Hauptgutachten der Monopolkommission 1990/1991} (http://dipbt.bundestag.de/doc/btd/12/030/1203031.pdf vom 16.08.2016). \bibitem[Monopolkommision (2016)]{monopol2016} Monopolkommision (2016): \em{Wettbewerb 2016: Einundzwanzigstes Hauptgutachten der Monopolkommission gemäß § 44 Abs. 1 Satz 1 GWB} (http://www.monopolkommission.de/index.php/de/gutachten/hauptgutachten/liste-hauptgutachten vom 21.09.2016).  \end{thebibliography}   what is wrong here? these are the packages i used.  \documentclass[oneside,12pt,german , a4paper]{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage[backend=biber,style=authoryear]{biblatex} \usepackage{geometry} \usepackage[graphicx]{realboxes} \usepackage{lmodern} \usepackage{setspace} \usepackage{caption} \usepackage{eurosym} \usepackage{import} \usepackage{float} \usepackage{biblatex} \usepackage{pdflscape} \usepackage{multirow} \usepackage{pbox} \usepackage{filecontents} %\usepackage{acro} \usepackage[printonlyused]{acronym} \usepackage[bottom]{footmisc} \geometry{  a4paper,  total={210mm,297mm},  left=45mm,  right=15mm,  top=25mm,  bottom=15mm,  }  \graphicspath{ {images/} } \onehalfspacing \captionsetup{justification=raggedright,singlelinecheck=false} \nocite{*}   I did have some renewcommand, but I think this is not the cause.  \makeatletter %\renewcommand{\bibname}{Literaturen} \renewcommand{\contentsname}{Inhalt} %\renewcommand{\acronymname}{Abkürzungsverzeichnis} \renewcommand{\figurename}{\textbf{Abbildung}} \renewcommand\listfigurename{Abbildungsverzeichnis} \renewcommand\listtablename{Tabellenverzeichnis} \renewcommand\@biblabel[1]{} \renewcommand\footnotesize{%    \@setfontsize\footnotesize\@ixpt{10}%    \abovedisplayskip 8\p@ \@plus2\p@ \@minus4\p@    \abovedisplayshortskip \z@ \@plus\p@    \belowdisplayshortskip 4\p@ \@plus2\p@ \@minus2\p@    \def\@listi{\leftmargin\leftmargini                \topsep 4\p@ \@plus2\p@ \@minus2\p@                \parsep 2\p@ \@plus\p@ \@minus\p@                \itemsep \parsep}%    \belowdisplayskip \abovedisplayskip } \makeatother   I think I post in the wrong website since nobody answer me on Stackoverflow.

Equation of a rectangle I need to graph a rectangle on the Cartesian coordinate system. Is there an equation for a rectangle? I can't find it anywhere. I several days ago somewhere read that category and tag pages should be noindexed. But later on somewhere else, I read that, they only increase rank for search term, but overall traffic decreases- said one from his experience.  So, if I just concern about traffic, not about individual search term that much, should I make those category and tag pages as indexed to google? I am confused which is the best to do.  Thanks in advance.  Regards Rana I want to split a long equation in many lines I have a long line in equation. I want to split it properly in two or three lines. I've been using \begin{split} and \end{split}, but still it is not in good position. The equation's code is below.  \begin{equation} \begin{split} \frac{r(r-1)c_{0}}{z} + \\ &amp;  \sum_{0}^{\infty}[[(j+r)(j+r+1)c_{j+1} - [(j+r)(j+r-1) - l(l+1)]c_{j}] \\ &amp;= 0, \end{split} \end{equation} Intersecting overlapping polylines using ArcGIS for Desktop? I have 4 multipart polyline shapefiles (download a sample dataset ).   The geometries are identical, except for the length of segments in each shapefile. They represent 4 variables describing an identical shoreline. From these 4 overlapping polylines, I would like to create a resulting polyline that has segments for each unique set of the 4 input lines.    My approach was to use an intersect. This, however, breaks down when I try to run it on 4 huge feature classes.  My question is whether there is a more efficient way to combine polyline attributes stored in separate layers. I thought a union would be good, but it only works on polygons. Spatial Join seems inefficient, as I would end up with many to many joins for a single segment. Turning the segment end points into a point layer, then splitting the line at those points?  I have access to arcpy, PostGIS, and shapely.  Has anyone had experience doing this before on large datasets? Is there a more efficient way to store these variables?

An .mov video that is upside down in Windows appears right side up in OSX How do you convert CString and std::string std::wstring to each other? CString is quite handy, while std::string is more compatible with STL container. I am using hash_map. However, hash_map does not support CStrings as keys, so I want to convert the CString into a std::string. Writing a CString hash function seems to take a lot of time. CString -----&gt; std::string  How can I do this? std::string -----&gt; CString:  inline CString toCString(std::string const&amp; str) {     return CString(str.c_str());  }  Am I right?  EDIT: Here are more questions: How can I convert from wstring to CString and vice versa? // wstring -&gt; CString std::wstring src; CString result(src.c_str());  // CString -&gt; wstring CString src; std::wstring des(src.GetString());  Is there any problem with this? Additionally, how can I convert from std::wstring to std::string and vice versa? How to switch between tty and xorg session I know that it holds for $n=5$, so the first step is done.  For the second step, my IH is: $4^n &gt; n^4$, and I must show that $4^{n+1} &gt; (n+1)^4$. I did as follows:  $4^{n+1} = 4*4^n &gt; 4n^4$, and if I show that $4n^4 &gt; (n+1)^4$ holds for $n\geq 5$ I'm done, so I expand the right hand side and arrive to:  $$4n^4 &gt; n^4 + 4n^3 + 6n^2 + 4n + 1$$  And this holds iff: $$3n^4 - 4n^3 - 6n^2 - 4n - 1 &gt;0$$ And here I'm stuck, I don't really know how to show that the given inequality holds. Any hints? How to find sum of power series $\sum_{n=0}^\infty\frac{1}{n!(n+2)}$ by differentiation and integration? Let $$ S = \sum_{n=0}^\infty \frac{1}{n!(n+2)} $$  Integrate the Taylor Series of $xe^x$ to show that S = 1  Also, Differentiate the Taylor series of $\frac{e^x - 1}{x}$ to show that S = 1  For the integration one, I got $\int xe^x dx$ = $x^2\sum_{n=0}^\infty \frac{1}{n!(n+2)} x^n$ and pretty much stuck. I can see the S term but i have no idea how to move on from there Because of past conflicts, I don't believe my advisor will write me a good LOR for postdoc positions. What should I do? I was wondering how to create a theorem environment similar to the following example:   Specifically, the environment should resemble the box that contains "Claim -- The function g is linear".

What does it mean to colour separate the artwork for T-Shirt printing? It is normally suggested to use Pantone colours for T-Shirt printing. Is it the Pantone Coated or the Pantone Uncoated? The Uncoated one has more subtle colours and we can't choose brighter shades if the design requires that. What is more appropriate for printing? Can we use gradients in T-Shirt printing or is it suggested to stick to flat colours only?   The reason for asking if gradients were ok was to use it as an option for this design:    I was considering it an option, as it will be difficult to colour separate since the textures are clip masked inside the lion.
