when the wireless signal weakens. The new technology called streamloading could make spotty streaming and data-hogging downloads a thing of the past.
In the simplest terms streamloading makes use of a video format that splits the video into two layers#a base layer
Traditional streaming involves downloading 30 to 60 seconds of video ahead of time with the video quality and speed varying depending on wireless signal strength.
Streamloading allows users to pre-download the enhancement layer onto their devices in a location where wireless signal is strong#at home for example#and stream only the base layer at the time of viewing.
Shivendra S. Panwar professor of electrical and computer engineering the Polytechnic institute of New york University and the lead developer of streamloading estimates that the technique could remove as much as 75 percent of the streaming content from increasingly overloaded cellular wireless networks
while at the same time reducing high data usage charges for consumers Panwar explains that#in the best-case scenario we ll at the same time relieve some of the bandwidth crunch for wireless carriers
Although users will technically be downloading and saving content on their devices#something that s prohibited by streaming content services like Netflix#Panwar explains that
The National Science Foundation and the Center for Advanced Technology in Telecommunications (CATT) at NYU-Poly support the work.
#Computer picks emotion based on brain scan CARNEGIE MELLON (US) For the first time, scientists have identified which emotion a person is experiencing based on brain activity.
combines functional magnetic resonance imaging (fmri) and machine learning to measure brain signals to accurately read emotions in individuals.
because the impact of film clips diminishes with repeated display. The researchers solved the problem by recruiting actors from the School of Drama. ur big breakthrough was my colleague Karim Kassam idea of testing actors,
The computer model, constructed from using statistical information to analyze the fmri activation patterns gathered for 18 emotional words
The computer model achieved a rank accuracy of 0. 84. Rank accuracy refers to the percentile rank of the correct emotion in an ordered list of the computer model guesses;
random guessing would result in a rank accuracy of 0. 50. Next, the team took the machine learning analysis of the self-induced emotions to guess which emotion the subjects were experiencing
when they were exposed to the disgusting photographs. The computer model achieved a rank accuracy of 0. 91.
With nine emotions to choose from, the model listed disgust as the most likely emotion 60 percent of the time and as one of its top two guesses 80 percent of the time.
Finally, they applied machine learning analysis of neural activation patterns from all but one of the participants to predict the emotions experienced by the hold out participant.
when the computer model made use of activation patterns in only one of a number of different subsections of the human brain. his suggests that emotion signatures aren limited to specific brain regions,
but produce characteristic patterns throughout a number of brain regions, says Vladimir Cherkassky, senior research programmer in the psychology department.
for Agricultural research for Development or CIRAD in France scrutinized the available field and laboratory data to test predictions about resistance.
and with the data accumulated over that period we have a better scientific understanding of how fast the insects evolve resistance and why.#
#Analyzing data from 77 studies of 13 pest species in eight countries on five continents the researchers found well-documented cases of field-evolved resistance to Bt crops in five major pests
#Computer models showed that refuges should be especially good for delaying resistance when inheritance of resistance in the pest is recessive#explains Carri##re.
#If the data indicate that the pest s resistance is likely to be recessive and resistance is rare initially the risk of rapid resistance evolution is low#Tabashnik says.
Although the new report is the most comprehensive evaluation of pest resistance to Bt crops so far Tabashnik emphasizes that it represents only the beginning of using systematic data analyses to enhance understanding and management of resistance.#
The progress made provides motivation to collect more data and to incorporate it in planning future crop deployments.#

Some of the photons are allowed to escape from the device to serve a purpose such as reading data off a CD or etching a circuit board.
#Stanford researchers are already using the polariton laser to develop quantum computers and quantum simulators. Kim believes similar lasers will be available to those outside the scientific community within the next five to 10 years.
Researchers conducted the work in collaboration with the National Institute of Informatics in Tokyo Japan and a team from the University of W##rzburg in Germany led by physicist Alfred Forchel.
The dynamo was developed through simulations using the high-performance computing facilities located at the University of Leeds.#The fact that it took 50 years

#Engineers have created a smartphone HIV test that costs $35 to make Let s be honest: Smartphones aren thought#t necessarily of as devices that help to slow the spread of sexually transmitted diseases.
In fact research has found that transmission rates go up when hookup sites#even ones on the tamer end like Craigslist#come to town.
But smartphones are also capable of transforming into competitive diagnostic tools as a team of biomedical engineers out of Columbia University is showing with their new attachment that can detect both HIV and syphilis in a single 15-minute test.
The dongle as the team writes in the journal Science Translational Medicine costs just $34 to make (an amount that could drop further if mass produced.
It uses the phone#s power and data collection and incorporates simple optics and fluid control to process a finger prick of blood.

#Autodesk is now selling an open-source 3d printer Autodesk first foray into hardware is here: The Ember 3d printer is now available for anyone to order.
At $5, 995, the printer isn exactly a steal. Autodesk more so built it to be the perfect exhibitor for its open-source Spark 3d printing software,
which is currently in beta. People married to Autodesk suite of software might find that pairing of interest,
but the greater 3d printing industry might buy Ember because Autodesk plans to release exactly how it is built
and operates. Makerbot, the best known desktop 3d printer brand, gave rise to an entire class of printers
because its first machines were similarly open source. Ember could do the same for a different desktop technology.
I had the chance to see Ember in action at Autodesk Pier 9 manufacturing space in San francisco. It a digital light processing machine,
which means it uses a projector similar to those found in those bulky classroom machines.
Light hits a shallow tank of liquid plastic and cures it one layer at a time, slowly building up an entire 3d object.
Unlike most desktop machines, which print layers of melted plastic that then hardens, DLP machines print upside down.
a necessary step in DLP printing. The Ember printer handles that last step in an unusual way.
The tank is shaped like a cashew; a half-instead of the square shape used by every other DLP printer.
After each layer is printed, the print platform raises slightly and the tank whips around the curve of the machine before returning to its home position.
Autodesk chose the unusual tank design because it requires the machine to use a lot less force, according to Autodesk 3d printing research scientist Andreas Bastian.
Each time the projector cures a layer, it creates a huge amount of suction between the 3d printed object and the bottom of the resin tank.
pending approval from the FCC. Autodesk has yet to release the actual open-source documentation for the machine,
but my personal run-in with the printer at Pier 9 was welcome confirmation that Ember really exists,

and can mill about with virtual versions of your high school class or family members who live on the other side of the world.
This virtual world could give a whole new meaning to the moniker virtual town square. Speaking of Second life the past-its-prime virtual world is already trying to get a jump on this by integrating Oculus Rift DK2 support into its social sandbox.
If autonomous cars become mainstream that would free us up to focus on other things while in the car.
