Are you referring to this paper ?

The authors didn't mention any numerical difficulties. Maybe it would have been worth contacting one of them for help--assuming you're not one of them.

I saw no mention of the EPA in the article.

However, were it not a troll, the "Try again." comment would bother me. Someone may have little to contribute to the thread except for a link to a journal article. Let them post it! It still gives information to a non-negligible subset of the slashdot readership.

The American cars are apparently more reliable than you remember.

I search for "amazon blu ray" because I want to buy a blu ray player on amazon.com. In my opinion amazon.com requires no advertising when a query asks specifically for them. The top hit is the relevant page on amazon.com. However, I automatically click on the ad instead because it's equally relevant and it sits higher on the page.

Maybe if Amazon hadn't paid for that ad, a competitor would have and the sale would be stolen some small percentage of the time. If that chance is small, then companies are paying for a lot clicks they would have had for free. Regardless, I've clicked on many google ads without even realizing what I had done.

That could be why dermatology is one of the most competitive residency programs to get into.

I do know how much medical school costs; it's outrageous and there's no doubt it turns off qualified people. You might say that the most passionate should be undeterred, but I don't think that's realistic.

I wouldn't be surprised if the amount of debt accumulated in professional programs selects for the type who are fixated on the pot of gold at the end.

x = vector(mode="list")
x[["joe"]] = y
x[["bob"]] = z #z can be a function!

x = list(joe=y)
x$bob = z

x = 1:10 #integers from 1 to 10

#set all even elts of x that are less than 7

x[(x < 7)&(x %% 2 == 0)] = -1

#y is some big array with several dimensions

#I and J are vectors of integers

z = y[I,,J,,, drop = F]

#'z' is now a sub array

z = y[I,2,J,1,]

#now z is a subarray with fewer dimensions
