The experiment shows that researchers can now accurately observe the type of neutrino oscillation that will need to be studied in detail in future experiments aiming to measure CP violation explains Steven Manly professor of physics at the University of Rochester and part of the collaboration.
For that reason the University of Rochester group has focused on understanding these other processes to ensure that what is measured is really the neutrino oscillation they have sought.

#iphone artists help solve#fat finger#problem CARNEGIE MELLON (US) Using the data amassed with an iphone drawing game,
researchers have built a tool that improves touchscreen art. The fingers of thousands of people who created sketches of Brad pitt
and Angelina jolie on their iphones can collectively guide and correct the drawing strokes of subsequent touchscreen users in an application created by researchers at Carnegie mellon University and Microsoft Research.
The app compensates for the at fingerproblem associated with touchscreens, automatically correcting a person drawing strokes
while preserving the user artistic style. ur goal was to make it invisible to the user, so people wouldn even be aware the correction is taking place,
says Alex Limpaecher, a Ph d. student in Carnegie mellon University computer science department. Adrien Treuille, associate professor of computer science and robotics, says the drawing assistance app is just one example of how Big data can be used to enhance drawing
and writing on touchscreens and even provide deep insights into art and perception. The trick has been to create drawing databases large enough to leveragen obstacle that he
and his research team surmounted with an iphone drawing game. The game they created, Drawafriend

#Online education Exploding at Campuses Across the country Like most other undergraduates, Anish Patel likes to sleep in. Even though his Principles of Microeconomics class at 9: 35 a m. is just a five-minute stroll from his dorm,
The floor was awash in the flotsam of three freshmen clothes, backpacks, homework, packages of Chips Ahoy and Cap Crunch Crunch Berries.
The University of Florida broadcasts and archives Dr. Rush lectures less for the convenience of sleepy students like Mr. Patel than for a simple principle of economics:
1, 500 undergraduates are enrolled and no lecture hall could possibly hold them. Dozens of popular courses in psychology, statistics, biology and other fields are offered also primarily online.
Students on this scenic campus of stately oaks rarely meet classmates in these courses. Online education is known best for serving older,
nontraditional students who can not travel to colleges because of jobs and family. But the same technologies of istance learningare now finding their way onto brick-and-mortar campuses,
especially public institutions hit hard by declining state funds. At the University of Florida, for example
resident students are earning 12 percent of their credit hours online this semester, a figure expected to grow to 25 percent in five years.
This may delight undergraduates who do not have to change out of pajamas to ttendclass.
But it also raises questions that go to the core of a college mission: Is it possible to learn as much
when your professor is a mass of pixels whom you never meet? How much of a student education and growth academic and personal depends on face-to-face contact with instructors and fellow students?
hen I look back, I think it took away from my freshman year, said Kaitlyn Hartsock,
a senior psychology major at Florida who was assigned to two online classes during her first semester in Gainesville. y mom was really upset about it.
She felt like she paying for me to go to college and not sit at home and watch through a computer.
Across the country, online education is exploding: 4. 6 million students took a college-level online course during fall 2008, up 17 percent from a year earlier, according to the Sloan Survey of Online learning.
A large majority about three million were enrolled simultaneously in face-to-face courses, belying the popular notion that most online students live far from campuses,
said Jeff Seaman, co-director of the survey. Many are in community colleges, he said. Very few attend private colleges;
families paying $53, 000 a year demand low student-faculty ratios. Colleges and universities that have plunged into the online field,
mostly public, cite their dual missions to serve as many students as possible while remaining affordable,
as well as a desire to exploit the latest technologies. At the University of Iowa, as many as 10 percent of 14,000 liberal arts undergraduates take an online course each semester,
including Classical mythology and Introduction to American Politics. At the University of North carolina at Chapel hill, first-year Spanish students are offered no longer a face-to-face class;
the university moved all instruction online, despite internal research showing that online students do slightly less well in grammar
and speaking. ou have X amount of money, what are you going to do with it? said Larry king, chairman of the Romance languages department,
where budget cuts have forced difficult choices. ou can be all things to all people. The University of Florida has faced sweeping budget cuts from the State Legislature totaling 25 percent over three years.
That is a main reason the university is moving aggressively to offer more online instruction. e see this as the future of higher education,
said Joe Glover, the university provost. uite honestly, the higher education industry in the United states has not been tremendously effective in the face-to-face mode
if you look at national graduation rates, he added. t the very least we should be experimenting with other modes of delivery of education.
A sampling of Florida professors teaching online found both enthusiasm and doubts. would prefer to teach classes of 50
and know every student name, but that not where we are financially and space-wise,
said Megan Mocko, who teaches statistics to 1, 650 students. She said an advantage of the Internet is that students can stop the lecture
and rewind when they do not understand something. Ilan Shrira, who teaches developmental psychology to 300,
said that he chose his field because of the passion of a professor who taught him as an undergraduate.
But he thought it unlikely that anyone could be inspired so by an online course Kristin Joos built interactivity into her Principles of Sociology course to keep students engaged.
There are small-group online discussions, and students join a virtual classroom once a week using a conferencing software called Wiziq. i, everyone, welcome to Week 9. Hello!
Dr. Joos said in a peppy voice recently to about 60 students who had logged on.
She sat at a desk in her home office; a live video feed she switched on at one point showed her in black librarian glasses and a tank top.
Ms. Hartsock, the senior psychology major, followed the class from her own off-campus home,
her laptop open on the dining room table. As Dr. Joos lectured, a chat box scrolled with studentscomments and questions.
The topic was sexual identity, which Dr. Joos defined as determination made through the application of socially agreed upon biological criteria for classifying persons as females and males.
She asked students for their own definitions. One, bringing an online-chat sensibility to an academic discussion
