Is it possible to create properties on the fly, with a .NET dynamic object?

A continuous, injective function $f: \mathbb{R} \to \mathbb{R}$ is either strictly increasing or strictly decreasing.

Concurrent and Blocking Queue in Java How to properly install Java in OS X How to parse a time into a Date object from user input in JavaScript? I am working on a form widget for users to enter a time of day into a text input (for a calendar application). Using JavaScript (we are using jQuery FWIW), I want to find the best way to parse the text that the user enters into a JavaScript Date() object so I can easily perform comparisons and other things on it.  I tried the parse() method and it is a little too picky for my needs. I would expect it to be able to successfully parse the following example input times (in addition to other logically similar time formats) as the same Date() object:   1:00 pm 1:00 p.m. 1:00 p 1:00pm 1:00p.m. 1:00p 1 pm 1 p.m. 1 p 1pm 1p.m. 1p 13:00 13   I am thinking that I might use regular expressions to split up the input and extract the information I want to use to create my Date() object. What is the best way to do this? Unless I missed something key during Descent 1/2, how is it that the Borg are once again a collective?

Does adverb placement affect meaning? He swam slowly to the island.  He slowly swam to the island.    Some experts say that there is a “slight difference” in meaning. Would you please tell me that difference? build argument lists containing whitespace In bash one can escape arguments that contain whitespace.  foo "a string"   This also works for arguments to a command or function:  bar() {     foo "$@" }  bar "a string"   So far so good, but what if I want to manipulate the arguments before calling foo?  This does not work:  bar() {     for arg in "$@"     do         args="$args \"prefix $arg\""     done      # Everything looks good ...     echo $args      # ... but it isn't.     foo $args      # foo "$args" would just be silly }  bar a b c   So how do you build argument lists when the arguments contain whitespace? Is there any online resource that can tell me what visa rules are for passport holders of a specific country? When thinking about travelling, I often have to think about a place to visit, and then look up visa rules for that particular country. This can be a fairly painful process because official government sites can often be hard to find, and advice on (say) guidebooks or Wikitravel tends to be generic.  Is there any resource where I can enter my nationality/residency, and then look up a list of visa rules for various countries? Good 1st PDE book for self study I can't delete more than 5 of my own posts in a single day. Is this a bug, or intended behavior? I'm trying to clean up old, crappy posts of mine.    Similar-looking problem, but it claims to be : $X^n-Y^m$ is irreducible in $\Bbb{C}[X,Y]$ iff $\gcd(n,m)=1$ I am trying to show that $X^n-Y^m$ is irreducible in $\Bbb{C}[X,Y]$ iff $\gcd(n,m)=1$ where $n,m$ are positive integers.    I showed that if $\gcd(n,m)$ is not $1$, then $X^n-Y^m$ is reducible. How to show the other direction. Please help. It started happening today... all of a sudden, no apparent reason!

My parents are Indian Citizens. They hold a valid B2 Tourist Visa to USA. I'm planning to book a flight with Hyderabad (India) - Abu Dhabi (UAE) - Dublin (Ireland) - USA. The leg from Hyderabad to Dublin is operated by Etihad and I know there is no problem hopping at Abu Dhabi. The leg from Dublin to US is operated by Aer Lingus. I called Aer Lingus customer care agent told me a transit visa is required to land in Dublin. She did not care to ask for the citizenship of traveller or about the USA visa. I went through Irish immigration website - (), India is not in list of countries that require transit visa. I'm now confused. Can some one confirm if they traveled with the same itinerary recently  Update: I called Aer Lingus again. Another agent told as long as I don't exit the airport, a transit visa is not required. I think these people don't really understand trouble we go through when boarding is denied. I put this question because I read a person was denied boarding earlier - . His case mentions about denied because of different day. But I see his transit time is 12 hours only.
