I'm trying to write \overset{\circ}{W}_2^{1,1} so that the circle lies on top of W AND the {1,1} superscript is not spaced differently due to putting the circle on W. So effectively I want the superscript {1,1} to appear as it would appear if I did not write the circle on top of W. Suggestions?
When I type $\overset{\circ}{Z}^\lambda$ the lambda is placed slightly above and to the right of the circle. Is there a way to make it appear as a superscript on the Z? I tried $\overset{\circ}{Z^\lambda}$, but then the circle is too high and to the right.  As a bizarre aside: a friend uses the exact same code with no problem. However, when I type it into MathOverflow it looks the same as in my compiler (i.e. bad).

Currently, the nominee's comments on his/her own post are not highlights, unless you click "add / show more comments"  When the page is loaded it looks like:    AfterI click "add / show more comments", it becomes:    Could we have the blue highlighting on the post owner's comments there all the time?

Using PTSerif-TLF for Cyrillic with TeX Gyre Pagella Why exactly do sometimes universal covers, and sometimes central extensions feature in the application of a symmetry group to quantum physics? There seem to be two different things one must consider when representing a symmetry group in quantum mechanics:   The universal cover: For instance, when representing the rotation group $\mathrm{SO}(3)$, it turns out that one must allow also $\mathrm{SU}(2)$ representations, since the negative sign a "$2\pi$ rotation" induces in $\mathrm{SU}(2)$ is an overall phase that doesn't change the physics. Equivalently, all representations of the Lie algebra are what we seek. ($\mathfrak{so}(3) = \mathfrak{su}(2)$, but although every representation of the algebra is one of the universal cover, not every representation of the algebra is one of $\mathrm{SO}(3)$.) Central extensions: In conformal field theory, one has classically the  of infinitesimal conformal transformations. From the universal cover treatment one is used to in most other cases, one would expect nothing changes in the quantum case, since we are already seeking only representation of an algebra. Nevertheless, in the quantization process, a  appears, which is often interpreted to arise as an "ordering constant" for the now no longer commuting fields, and we have to consider the  instead.   The question is: What is going on here? Is there a way to explain both the appearence of universal covers and central extensions in a unified way? I've tried several things already,  std::stringstream m; m.empty(); m.clear();   both of which don't work. Page returns 404 with POST variables, but not without I have a problem with my page. I'm trying to make a "Contact Us" page. It's working perfectly fine design-wise. But when I try to send the form to the same page as origin. It returns 404 error.  It only happens when I'm sending the form. I've tried both with GET and POST requests. Nothing seems to work.  I've even commented out the PHPMailer part. It's caused entirely by the extra variables.  If it helps anything, they're "name", "email" and "message". I'm interested in understanding which neural network architecture is currently the state of the art (sometimes abbreviated "SOTA") with respect to standard image classification tasks such as MNIST, STLN-10 and CIFAR. This is challenging because new results are published frequently, and it can be hard to keep up. Is there a resource or website which tracks the best results for these tasks? Do's and Don't's of Undergraduate Research I was fortunate enough to get a position as a researcher for the Mayo Clinic's SURF Program this year. My PI's lab focus is on the the immune system's role in CNS axonal and neuronal injury, specifically through the lens of how innate and adaptive immune effectors interact w/ infected neurons.  Although I do research under a professor at my college and I volunteered for a state university lab during the previous summer, this is my first REU/SURF opportunity, and I REALLY want to make a good impression. Here are my questions:  What are the do's and don't's in terms of being a skilled and efficient researcher?  Since I am still an undergrad, I know that I will be a less useful asset to the lab than a grad student or post-doc, but what can I do as an undergrad to not burden my colleagues and PI?  Thank you all for your help! Wishing you all the very best! Is it "I" or "me" in "Keep Tom and I/me updated"? Is there a way to replicate Nikon D3100 live view on my laptop screen? I own a Nikon D3100 and I need a way to see the live view of my camera on my laptop screen.  There must definitely be a way (I am not just aware of it). I have searched all around the web sites... I could not get a solution.  The Nikon Camera Control Pro 2 does not support D3100, and "Camera Control 5.1" connects and shoots remotely from a laptop but does not show live-view nor shoot in RAW.  There is a way of connecting my camera to a TV or monitor directly via an HDMI cable and getting the live view, but I want it displayed to my laptop screen.

You pick a   door, say No. 1, and the host, who   knows what's behind the doors, opens   another door, say No. 3, which has a   goat. He then says to you, "Do you   want to pick door No. 2?" Is it to   your advantage to switch your choice?   The answer is, of course, yes - but it's incredibly un-inituitive. What misunderstanding do most people have about probability that leads to us scratching our heads -- or better put; what general rule can we take away from this puzzle to better train our intuition in the future? Given the following data:  972, 975, 985, 993, 993, 995, 998, 1001, 1004, 1007, 1008, 1009, 1011, 1015, 1016, 1020, 1022, 1032  I calculate the lower quartile as follows:  Number of values: 18, Number of 'gaps': 17.  Lower quartile is at 17/4 + 1 = 5.25th value. 5.25th value is 993 + (995 - 993) x 0.25 = 993.5  Upper quartile is at 3 x 17/4 + 1 = 13.75th value. 13.75th value is 1011 + (1015 - 1011) x 0.75 = 1014  Both the Excel QUARTILE function and the R quantile function agree with me. However the book I am using (Understanding Statistics by Graham Upton and Ian Cook) give different answers (993 and 1015 respectively). I'm confused. Which is correct?

I'm looking for a word which describes a task which I think is poorly designed and will lead to either mediocre results or failure, but which I have to do anyway, especially in a work setting.   The word "Dilbertian" comes to mind, however this word is obviously made up and is only meaningful to someone who is familiar with the Dilbert comic strip, so I'm looking for something which captures both the futility and compulsory nature of the task in a way which is meaningful to a broader audience. There is a question I have based on the fact: If you take a quadratic polynomial with integer coefficients, take the set $\{1,2,3,4,5,6,7,8\}$, make a partition $A=\{1,4,6,7\}$, $B=\{2,3,5,8\}$, and then evaluate the polynomial with the elements of each set you got an equality.  If now with a cubic polynomial and the set $\{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16\}$, how to pick a suitable partition that accomplish the same fact? I mean is there a general formula for bigger degree?
