Is there an easy way to put a box around a theorem in LaTeX? For example to state an important theorem. I tried using page 20 of the ntheorem , but I do not know how to use the package.

Detection of the Electric Charge of a Black Hole Remove specific duplicates (all but latest) When removing duplicate rows, using the below query from  tutorial, how would I go about forcing which of the found duplicates to remove?  DELETE FROM dbo.ATTENDANCE      WHERE AUTOID NOT IN (SELECT MIN(AUTOID) _ FROM dbo.ATTENDANCE      GROUP BY EMPLOYEE_ID,ATTENDANCE_DATE)    And this works great. The reason why I am using this one is because the only unique id available is one in the IDENTITY column. And to determine if there are duplicate rows I have to look at a combination of multiple columns.    But if I have a set of duplicate rows how do I / how does SQL Server decide which to remove? And how would I force it to remove all but the one with the highest IDENTITY value?  EMPLOYEE_ID     ATTENDANCE_DATE     AUTOID A001            2011-01-01          1 A001            2011-01-01          2   If I would run the query now it happens to remove the second one, with AUTOID 2. But I am trying to remove all but this one (because this is the one latest added). I have a script that updates my desktop background every day with the NASA APOD. Since upgrading to 11.10, that script stopped working, presumably because I'm using gconftool-2 to actually update the desktop background.

I want to be a stockholder on record for a dividend. So lets assume I bought stock before the ex dividend date. Can I immediately sell the stock after the ex-dividend date to collect the dividend, or do I need to hold for a few weeks to collect the dividend?  Lets say the ex-dividend date is the 15th of the month. I buy stock on the 14th (I think this is soon enough to be a shareholder on record) and then I sell on the 15th. Do I get the dividend in my account when it is distributed?  Don't worry &ndash; I have a proprietary way of hedging the stock's post-dividend price adjustment, and it costs less than the actual dividend so all is well.  I just don't know what the shortest time I can hold a position is. I'd like to know the shortest theoretical time possible in order to get the dividend.  Insight appreciated. Converting Older United States Dollar Bills Ridge & LASSO norms This post follows this one:   Here is my question:  As far as I know, ridge regularization uses a $\ell_2$-norm (euclidean distance). But why do we use the square of this norm ? (a direct application of $\ell_2$ would result with the square root of the sum of beta squared).  As a comparison, we don't do this for the LASSO, which uses a $\ell_1$-norm to regularize. But here it's the "real" $\ell_1$ norm (just sum of the square of the beta absolute values, and not square of this sum).  Can someone help me to clarify?

According to the , Yachiru disappeared leaving her belongings after the fight with Gremmy. She is said to be "gone" by Kenpachi in the penultimate chapter of the original series.

How to make password-less login work I generated a key and copied it to my target:  ssh-keygen ssh-copy-id username@hostname   I left the the location of the key as default and did not set any passphrase.

How to implement Unit Test at Unity3D.   I wonder if it would be possible to extend the Unity editor to have some sort of testing framework in it.    Is there any guideline to implement it? Any reference like book, blog? Any working example or project? I was confused initially about what the pins mean next to a topic in the new help center.  "those articles are "featured" articles; they are meant to draw attention to the most important site policies or most frequently encountered issues."   If the pin is used to denote an important topic, it should at least be noted as such. Also a pin generally means to me that this is something that I personally selected.  Could their meaning be clarified somehow?
