Phys. Rev. Lett. 109, 074501 (2012): Revival of Classical Vortex Generators Now for Transition Delay

Without logging in, I just get what seems like a synopsis. Is that what you're getting?

The Abstract is an advert for the $25 product.

"Our experimental results show that these devices are really effective in delaying transition, but we also reveal their Achilles’ heel." ...oooh!

If this research was paid for with public money, then it's the sort of thing that protesting it got Aaron Swartz dead. I think that's grammatical. :)
