I have a problem with the way my bibliographic references turn up in the text. I use JabRef to handle the bibliography. In my preamble, I use the option maxcitenames and mincitenames to make sure that multiple authors (more than 2) will only be cited as "Firstauthor et al." in the document itself, while all the authors are listed in the bibliography. However, I have encountered the following curious problem. Two different papers that I need to quote are both written by four different authors, the first of which is the same in both cases.   Concretely, the author "Wiklund" is the first author of both papers. What I want, is of course the first reference to appear in the text as (Wiklund et al. 2007), and the other as (Wiklund et al. 2009). But somehow, Biber (or perhaps the problem is JabRef) feels it has to cite the second author in both cases to distinguish between the two.   Here is a MWE and below is a picture of what it produces + the JABREF source of the two relevant entries. Notice that if I only reference one of these entries, everything works fine and only (Wiklund et al. 2007) or (Wiklund et al. 2009) appears. The problem is caused by the co-occurrence of these entries.   \documentclass[12]{article}  \usepackage[backend=biber, style=authoryear-comp, sortcites=false, maxcitenames=2, mincitenames=1, maxbibnames=4]{biblatex}  \addbibresource{flafla.bib}  \begin{document}  Some text\parencite{Wiklundetal2007}. Some more text \parencite{Wiklundetal2009}    \printbibliography  \end{document}     @Article{Wiklundetal2009,   author =  {Wiklund, Anna-Lena and Benzen, Kristine and Hrafnbjargarson, Gunnar Hrafn and Hróarsdóttir, Thorbjörg},   title =   {On the distribution and illocution of V2 in Scandinavian that-clauses},   journal = {Lingua},   year =    {2009},   volume =  {119},   number =  {2},   pages =   {1914-1938} }  @Article{Wiklundetal2007,   author =  {Wiklund, Anna-Lena and Hrafnbjargarson, Gunnar Hrafn and Hróarsdóttir, Thorbjörg and Bentzen, Kristine},   title =   {Rethinking Scandinavian Verb Movement},   journal = {Journal of Comparative Germanic Linguistics},   year =    {2007},   volume =  {10},   pages =   {203-233} }
In the header of my document I set the maximal author names to 2:  \usepackage[style=authoryear-icomp, maxbibnames=9, maxcitenames=2, backend=biber]{biblatex}   Now, when I cite texts with two authors, LaTeX gives me the following:     (Author_A/ Author_B 2012: 232)   When I have three authors or more, LaTeX makes it:     (Author_A/ Author_B et al. 2012: 232)   But I want LaTeX to just name the first author if there are more than two authors ... like this:     (Author_A et al. 2012: 232)   Any tips on how to achieve this ?

I have an Asus UL30JT. It has Nvidia Optimus technology which I am not really interested in. I currently rarely use this laptop with it being connected to power. And I want to be able to play video at high res, play games and do some OpenCL coding.  In the BIOS I switched it to NVIDIA only (non windows 7). Previously, this worked just fine, using the nvidia driver.  After upgrading everything was broken. I have added nomodeset and blacklist.nouveau=1 as kernel options. The nvidia drivers install without error. However they are not found/used.  jockey-text -l kmod:nvidia_310_updates - nvidia_310_updates (Proprietary, Enabled, Not in use) kmod:nvidia_304_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_313_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_310 - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use) kmod:nvidia_304 - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use)   Trying to load the module manually fails as well.  sudo modprobe nvidia FATAL: Module nvidia not found.

I verified that the kernel options are in the grub configuration. I have purged all nvidia packages and tried to reinstall (multiple times...)  Currently I am at a loss. I have checked the following question:  But nothing there worked for me. Is there a good word for a square-rectangle relationship? Any given square is always a rectangle, but a rectangle isn't necessarily a square, so squares and rectangles have a _ relationship. I've been noticing this sort of thing everywhere ever since I noticed that I didn't know a good word for it. I've been calling it a container relationship because one class of things is contained within a larger class of things. However, a "container" relationship doesn't sound very good and doesn't really convey the meaning on its own. A more elegant word would be helpful.  Edit: A specific definition would be something like: a is always b. b is sometimes a. I'm more of a math guy than a physics guy so bear with me....  In fractal geometry, fractals are considered to have fractional dimension. For instance an object such as the Koch curve has a fractal dimension of around $1.2$. You can also define a concept called fractal extent (which is the experimental version of hausdorff measure). This extent is a measure of how large a fractal is. It's even been used to more accurately model the distribution of coastline bird nesting.   Even though fractals work as an interpretation of geometrical units, I don't think they would describe things such as $kg^{1/2}$ very well. In addition, I've heard about white Gaussian noise that has square root time units.   What is the physical meaning of fractional units such as the above? (Since it obviously has little geometric meaning) For only my index pages, I am receiving this warning in Google Search Console:     Duplicate, submitted URL not selected as canonical   I know that this occurs because Google is attempting to track both the default landing "page" (i.e. www.domain.example/) and the page to which to which DirectoryIndex points (i.e. www.domain.example/index.html). They are, in fact, the same page, and so the warning is the result of a false positive.  Two questions for our community:   Why does Google not conflate these and count them as a single page? Alternately, is there something wrong with my set up if this has happened? I can easily force both pages to point to a single canonical URL. But which is preferable, "/" or "index.html"? This question pertains to L1 &amp; L2 regularization parameters in Light GBM. As per official documentation:  reg_alpha (float, optional (default=0.)) – L1 regularization term on weights.  reg_lambda (float, optional (default=0.)) – L2 regularization term on weights  I have seen data scientists using both of these parameters at the same time, ideally either you use L1 or L2 not both together.   While reading about tuning LGBM parameters I cam across one such case: Kaggle official GBDT Specification and Optimization Workshop in Paris where Instructors are ML experts. And these experts have used positive values of both L1 &amp; L2 params in LGBM model. Link below (Ctrl+F 'search_spaces' to directly reach parameter grid in this long kernel)      I have seen same in XGBoost implementations.  My question is why use both at the same time in LGBM/XGBoost.  Thanks. "He walks as if he is drunk." Grammatically correct ? Any difference in meaning from "...as if he were drunk."? Is it grammatically correct to use an indicative verb after "as if", or "as though" for that matter?        I've heard someone say: "He walks as if he is drunk."  Would there have been any difference if he had said "He walks as if he were drunk."?   A second example might be:        It looks as if it is going to rain.   It looks as if it were going to rain. I know that this question is a bit old or maybe overdone, but I'm running the latest edition of Blender and when I use the Cycles engine I get really fuzzy results and I can't find a simple, non-compromising solution to the quality.  I don't know exactly what I'm doing wrong here, but I'm sure others share my frustration.  Leaving everything in default settings, I started a new project and switched to the Cycles render.  I duplicated the cube and set colors for two Diffuse BSDF shaders, then went ahead and made walls and a floor all sharing the same diffuse shader.  I made two windows to emit blue light.  The screenshot has gaps between the walls because of the setup:  I'm aware that it's considered very incomplete and many have come to terms with some amount of noise, but is this normal?  Furthermore, with default settings or not, I can't change the amount of noise produced.  Supposedly, using "progressively refine" in the rendering tab should make it refine itself indefinitely, however Cycles only counts to 10 refines and then stops, creating a render which is a pixel-perfect match of the ordinary rendering method when it's completed.  I understand that there are tricks that can be used to reduce noise, but at the cost of extra processing time and usually small quality conflicts, like blurring.  My question essentially boils down to is this Cycles' current limit? How do I rename all folders and files to lowercase on Linux? Convergence of exponential Brownian martingale to zero almost surely Define the exponential Brownian martingale as $N_t = \exp\left\{a W_t - \frac12 a^2 t \right\}$ which is a martingale with respect to the natural filtration of $W$ which stands for a standard Brownian motion.  I now want to prove that $N_t \rightarrow 0$ a.s. for $t \rightarrow \infty$. As $N_t$ is a martingale it is by definition in $L^1$ hence Doob's martingale convergence theorem tells us that there exists a $N_\infty \in L^1$ such that $N_t \rightarrow N_\infty$ a.s., but how could I prove that $N_\infty \equiv 0$? Any help is greatly appreciated! Alignment of numbers on the individual bars Get the client IP address using PHP Answer turned to CW, votes pre-CW era doesn't count in tag specific stat My understanding is that if an answer becomes CW (one way or another), original author gets to keep the votes pre-CW.  Does this also keep the pre-CW vote count for the tag-specific stat? It doesn't look like it, because I checked recently and suddenly my number dropped. It looks like the tag-specific stat just counts votes for non-CW answers, and doesn't "discriminate" between the pre-CW and post-CW era. If it's eventually CW, then it simply contributes 0 votes.  I'm fine with the fact that my answer became CW (in this case, through the question having 30+ answers), but I would like to keep the votes I earned before it did for the tag stat.  Otherwise I think the system is "broken". Someone can go posting 30+ answers to questions where Jon Skeet answered, and all of Jon Skeet's answers would become CW, and he'd then be 0 at all tags.

How did Enrico Fermi calculate the classical Fermi Problem? From Wikipedia: Fermi was known for his ability to make good approximate calculations with little or no actual data, hence the name. One example is his estimate of the strength of the atomic bomb detonated at the Trinity test, based on the distance travelled by pieces of paper dropped from his hand during the blast. Fermi's estimate of 10 kilotons of TNT was remarkably close to the now-accepted value of around 20 kilotons, a difference of less than one order of magnitude.  I have not been able to find any references explaining how he made this calculation. Please provide a reference or an example calculation.
