Regular expression to extract text between square brackets
I was reading a  where the author mentions: "The coefficient of variation is primarily a descriptive statistic, but it is amenable to statistical inferences such as null hypothesis testing or confidence intervals. Standard procedures are often very dependent of the normality assumption and current work is exploring alternative procedures which are less dependent on this normality assumption."  The paper is from 2010. So my question is: has there been any recent "advancements" in terms of a coefficient of variation statistic that is not dependent upon the normality assumption? And, is this what one may call a non-parametric CV? Comparison between integrals Let's say - $F(x) &gt; G(x)$ for all $x$ in $E$.  So is it true that ?  $$\int F(x)\,dx  &gt; \int G(x)\,dx$$ or I can use this statement only when the two functions are non-negative functions.  Thanks! I've been taking photographs for a while, and have started to think about moving to full-frame. I'm on a very limited budget, but I currently have a good macro lens and am quite willing to buy something like a EF 50mm f/1.8 to start off with. I could possibly stretch my budget as far as a 70-200 f/4 L or 24-105 f/4 L.  Primarily, I'm interested in taking photos of small wildlife like reptiles, amphibians and insects, but I have a healthy interest in landscapes, birds and street photography.   I currently have an EOS 30D, and I love the way the camera handles, especially with the dual control dials. For this reason, I think shooting with a Rebel would be a significant step down.   However, I have seen 5Ds and occasionally 1Ds Mark IIs on ebay for roughly the same price as an EOS 650D. I'm sure these cameras have better IQ than my 30D, since they are pro-level bodies from around the same time, and full-frame besides. The question is, are these cameras now so old that the image quality from them is a substantial step down from current Rebels?   I realise I'll be giving up continuous shooting speed and some amount of low-light performance, and that I'd also need to get an external flash, but besides these, are there any substantial caveats I need to be aware of before I go ahead and take the plunge? How do you remove the ability for a user to make a comment or post on a page? I am building a new website on Wordpress, and all my pages have the add comment box at the bottom. I wish fo rthis to be removed from pages such as Home, Contact Us, About etc etc, but want it to remain on the blogs and galleries.  I have read  but do not really understand what this means to do. is there an easier way to do it. I do not have  under Settings -> Discussions. I see an equation like this:  $$y\frac{\textrm{d}y}{\textrm{d}x} = e^x$$  and solve it by "separating variables" like this:  $$y\textrm{d}y = e^x\textrm{d}x$$ $$\int y\textrm{d}y = \int e^x\textrm{d}x$$ $$y^2/2  = e^x + c$$  What am I doing when I solve an equation this way?  Because $\textrm{d}y/\textrm{d}x$ actually means  $$\lim_{\Delta x \to 0} \frac{\Delta y}{\Delta x}$$  they are not really separate entities I can multiply around algebraically.    I can check the solution when I'm done this procedure, and I've never run into problems with it.  Nonetheless, what is the justification behind it?  What I thought of to do in this particular case is write  $$\int y \frac{\textrm{d}y}{\textrm{d}x}\textrm{d}x = \int e^x\textrm{d}x$$ $$\int \frac{\textrm{d}}{\textrm{d}x}(y^2/2)\textrm{d}x = e^x + c$$  then by the fundamental theorem of calculus  $$y^2/2 = e^x + c$$  Is this correct?  Will such a procedure work every time I can find a way to separate variables? How to set AUTO-SCROLLING of JTextArea in Java GUI? Personal Hotspot not working over Wi-Fi on iOS 13 After upgrade to iOS 13 from 12.4, I noticed that personal hotspot isn't working anymore over Wi-Fi (via USB is ok).  Tested on two computers with Win7. The PC can connect to Wi-Fi, but no valid IP (IPv4) is assigned and no connection is working to internet. Java's Virtual Machine and CLR As a sort of follow up to the question called , what is the (major) differences or similarity in how the Java Virtual Machine works versus how the .NET Framework Common Language Runtime (CLR) works?  Also, is the .NET framework CLR a "virtual machine" or does it not have the attributes of a virtual machine? I need to repair my Windows 10 installation. Where can I get a clean ISO (with install.wim, no Install.ESD, so that I can run DISM against the WIM) of the specific Windows 10 build required for this?  In my case, I need the Anniversary update (Build 14393), Creators Update (Build 15063) or Fall Creators Update (Build 16299.15). Accelerating particles to speeds infinitesimally close to the speed of light? Some examples include:     We fear the damned.   He honored our fallen.   This is a given.   You are the chosen.   The lost were among us.   They obey the venerated.   My beloved kissed me. (TIL “beloved” is a verb thanks to RegDwight АΑA)   Is there a word to describe the past participle used as a noun? I’m hesitant to refer to it as a gerund, since it doesn’t end in -ing. Another possibility is adjectival noun, if you originally treat the word as a participle (e.g. “the damned man”) that has given up its modified noun.  Also, why does English tend to preface such nouns with the? Could gravity accelerate light? Gravity causes anything with energy to accelerate toward the source. Black holes, for example, have such strong gravity that they pull in light and don't let any escape. But can acceleration still apply to light? The speed of light is constant, of course, but why are photons affected by gravity yet aren't accelerated by it?  Edit: My main question is why photons aren't affected in the same way as most other particles. I'm perfectly aware that it cannot surpass lightspeed, but I want to know what makes it unaffected by acceleration while other particles are affected. I see people say statement as question while speaking by raising their voice at the of it to mean it's a question.   For example consider followings.         You want to stay here? ==> Is used to mean "Do you want to stay here?"   You guys spoke to anyone? ==> Is used to mean "Did you guys speak to anyone?"      Are these really used by native speaker in casual speech? And can I write them in the same way while writing them as dialogue by putting them between quotes? Are there any special grammar rules for these kind of questions? Please explain the meaning of "otherwise than" in this sentence Please explain the meaning of the second part and explain "otherwise than" in part b     a person’s UK property business consists of:      (a) every business which the person carries on for generating income from land in the United Kingdom; and      (b) every transaction which the person enters into for that purpose otherwise than in the course of such a business. Display date/time in user's locale format and time offset I want the server to always serve dates in UTC in the HTML, and have JavaScript on the client site convert it to the user's local timezone.  Bonus if I can output in the user's locale date format. I understand Big-O notation, but I don't know how to calculate it for many functions. In particular, I've been trying to figure out the computational complexity of the naive version of the Fibonacci sequence:  int Fibonacci(int n) {     if (n &lt;= 1)         return n;     else         return Fibonacci(n - 1) + Fibonacci(n - 2); }   What is the computational complexity of the Fibonacci sequence and how is it calculated? I have put a bounty on , however I don't see it appear in the  (also not when I'm not logged in).  Why is this. Aren't all bounty questions supposed to be visible there? What does "65" mean? K-2SO beats up the troopers easily. Up in the sky, the bombers are preparing to attack. Just as they start the attack run, TIE fighters come in from the shield and swarm the rebel fleet.  JON VANDER (GOLD LEADER): Red Leader, this is Gold Leader, we’re starting our attack run on the  shield gate. Keep it tight and watch out for those towers. GOLD PILOT: More fighters. Form up, at 65.  What does &quot;65&quot; mean? If a warlock's invocation states that they can use a spell without a slot does that mean they can cast the spell as often as they want? On page 111 of the 5E hand book the invocations Misty Visions, Mask of Many Faces, Master of Myriad Forms, and Otherworldly Leap all they that you can cast them without expending a spell slot. Does this mean the spells essentially become cantrips and I can cast them as often as I want? Are there rules about using "that" to join two clauses?
