A novel encryption method devised by MIT researchers secures data used in online neural networks, without dramatically slowing their runtimes. This approach holds promise for using cloud-based neural networks for medical-image analysis and other applications that use sensitive data.
University of Melbourne researchers have developed a software tool that uses applied mathematics and big data analytics to predict the boundary of where a landslide will occur, two weeks in advance.
It's nearly impossible to break a dry spaghetti noodle into only two pieces. A new MIT study shows how and why it can be done.
The number of people who died as a result of Hurricane Maria -- which hit Puerto Rico on Sept. 20, 2017 -- may be as high as 1,139, surpassing the official death count of 64, according to researchers.
Animals often rely on their sense of smell to locate food. It's a law of nature: the first one to reach a food source has a better chance of surviving than those who do not. But how exactly does their brain translate scent and then navigate towards it?
A group of data scientists conducted an in-depth analysis of major innovations and stock market bubbles from 1825 through 2000 and came away with novel takeaways of their own as they found some very distinctive patterns in the occurrence of bubbles over 175 years. The study, "Two Centuries of Innovations and Stock Market Bubbles," will be published in the INFORMS journal Marketing Science.
'The model we developed is richer than the classic theory because, among other reasons, it takes into account a more realistic treatment of financial markets in which various investors have different investment strategies,' the researchers say. 'Investors differ in the amount of risk they are willing to assume, and therefore choose different proportions of investments in risky assets, such as equities.'
The organization of our friendships is guided to a large degree by our cognitive capacity when it comes to managing them, that is, by the amount of time and mental effort we can devote to them. This is one of the conclusions of a study which was published by researchers from Universidad Carlos III de Madrid (UC3M) and the University of Oxford and which analyzed these relationships from a mathematical perspective. The study has been published in the latest issue of the PNAS journal.
Mathematicians at the University of Kent, with input from the University of Sheffield, have established that current restrictions on academics applying for research grants are causing major problems, harming smaller institutions and minorities in the process. To reduce the time and money spent evaluating applications, many funding bodies responded by restricting the number they receive.
An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has discovered that folding is an efficient strategy to incorporate large-area monolayer graphene films on polymer composites and that doing so improves mechanical reinforcement. Their work has been published in the prestigious journal, Advances Materials.
