Researchers have proposed a strategic approach for information spreading via Facebook using cancer screenings as a health intervention. They use Facebook to identify social clusters and opinion leaders and mathematically determine the best way to spread information, using health information as the subject.
Do you remember the 3-D-display from 'Back to the Future 2'? On back to the future day (Oct. 21) these displays may not yet be seen in our streets as the movie predicted, but the basic science is there. Researchers are now presenting a prototype for 3-D displays that work without 3-D glasses.
Researchers have developed an automated 'debugging' approach called Adaptive Multimodal Bug Localisation (AML). AML gleans debugging hints from both bug reports and test cases, and it performs a statistical analysis to pinpoint program elements that are likely to contain bugs.
A single-electron transistor is an electrical device that takes advantage of a strange quantum phenomenon called tunneling to transport single electrons across a thin insulator. The device serves as an on/off switch on the tiniest scale and could play an important role in quantum computing.
What's the best time to tweet, to ensure maximum audience engagement? Researchers have demonstrated that an algorithm that takes into account the past activity of each of your followers -- and makes predictions about future tweeting -- can lead to more 'retweets' than other commonly used methods, such as posting at peak traffic times.
A new physical effect has been discovered: Researchers have found a change of electrical resistance in magnetic whirls. Tiny magnetic whirls – so called skyrmions – are being considered as promising candidates for bits in future robust and compact data storage devices. These exotic magnetic structures were recently found to exist in ultrathin magnetic layers and multilayers, similar to the ones used in current hard-disk drives and magnetic sensors. However, up to now an additional magnet was necessary for a read-out of skyrmions.
Flying cars, hoverboards and video chat – a very futuristic vision for the year 2015 was presented in the movie “Back to the Future Part II”, released in 1989. Now, shortly before “Back to the Future Day” on October 21st, 2015, it is time to check whether reality has indeed kept up with the daring predictions of the 80s.
As the push for thinner and faster electronics continues, a new finding could help inform the design of the next generation of cheaper, more efficient devices.
A new report shows that a machine learning model using Department of Defense and Army administrative records was able to identify in advance the 5 percent of US Army soldiers serving from 2004 to 2009 who later committed more than one-third of all major Army workplace violent crimes over that time period.
Scientists estimate that we are losing species at 1,000 times the natural background rate. New technologies are improving conservation efforts by making it easier, faster, and cheaper to monitor threatened species. But technologies alone cannot conserve biodiversity, a new multi-institutional study finds. The challenge is to use technology more wisely, connect different technologies, and get appropriate technologies into the hands of those than can use them more effectively.
A study probes how factors that affect how quickly people respond to email. The researchers are also able to predict when an email thread will fizzle out. When users first email each other, they mimic each other with regards to the length of emails, but as the email chain continues, this synchronicity drops off. In general, users are synchronized until the middle of the conversation. The researchers identify telltale signs that the person with whom you are emailing isn't going to respond again. A long delay in the final response signals to both parties that the conversation is probably over.
Smartphones are so ubiquitous, and text messaging and social media activities so common in public places, that no one questions what anyone does with their phone. That pervasiveness allows a phone application to be used in direct, concealed observations without alerting the people being observed.
The superconductivity effect has been revealed by researchers which, they say, will help to create future supercomputers. The researchers studied the interactions between superconductivity and magnetization in order to understand how to control electron spins (electron magnetic moments) and to create the new generation of electronics.
A team of engineers has built a quantum logic gate in silicon for the first time, making calculations between two qubits of information possible -- and thereby clearing the final hurdle to making silicon quantum computers a reality.
Using microfluidic passages cut directly into the backsides of production field-programmable gate array devices, researchers are putting liquid cooling right where it's needed the most -- a few hundred microns away from where the transistors are operating.
Researchers have reached striking results in their recently published paper Understanding the detection of fake view fraud in Video Content Portals. For the first time, it has been demonstrated that video portals are very vulnerable to fraud by fake views from robots (bots).
The world's first entirely light-based memory chip to store data permanently has been developed by material scientists. The device, which makes use of materials used in CDs and DVDs, could help dramatically improve the speed of modern computing.
The calibrated library of compact models will enable improved accuracy and reliability in photonic integrated circuit design and fabrication.
First introduced in the United States in 2007, electronic cigarettes have risen dramatically in part because they are popularly considered safer and more socially acceptable than combustible cigarettes and because there are fewer restrictions on their purchase and use. A study now points to aggressive online marketing tactics that make purchasing e-cigarettes easy for all ages.
A researcher surveyed video game players about their views of characters with unrealistic bodies and found that they objected to the exaggerated and highly sexualized physiques in the games.
