University of Rochester researcher Dr. Glenn Rechtine, whose findings are published in the Journal of Bone and Joint Surgery, said: "We know that nicotine increases pain. In this study, if you quit smoking during treatment, you got better. If you continued to smoke, there was statistically no improvement, regardless of the treatment you had."
University of Rochester graduate student Na Yang, who co-authored the research paper, has already developed a Windows Phone smartphone app, Listen-n-Feel, that functions as a "mobile emotion sensor" and allows the phone to detect a speaker's feeling, showing a smiley face or frown-y face depending on the speaker's tone. "We actually used recordings of actors reading out the date of the month -- it really doesn't matter what they say, it's how they're saying it that we're interested in," said Wendi Heinzelman, a professor of electrical and computer engineering at the University of Rochester, according to a press release issued by the university.
Radar and lidar systems bounce radio or light signals off an object and measure how long they take to return. That information can be used to determine the object's position and shape - identifying it as a war plane, say - or to calculate its speed. But both military and police systems can be fooled by devices that generate photons of the same frequency as in the outgoing beam. This is how the speed gun jammers installed in some cars work.
To reveal when returning photons have been faked, Mehul Malik and colleagues at the University of Rochester, New York, borrowed a trick from quantum cryptography, polarizing each outgoing photon in one of two ways according to a sequence.
