By analyzing a century of data (1910 to 2010) in the American Film Institute Archive and the Internet Movie Database (IMDb), the researchers found that female representation in the film industry hit an all-time low during the so-called Golden Age.
A team of medical researchers and bioethicists at Oxford University has published results today in Science that furthers our understanding of coronavirus transmission. This evidence is enabling several international partners to assess the feasibility of developing mobile apps for instant contact tracing in record time. If rapidly and widely developed, these mobile apps could help to significantly slow the rate of transmission, and support countries to emerge from lockdowns safely, as restrictions are gradually eased.
Using the same technology that allows high-frequency signals to travel on regular phone lines, researchers tested sending extremely high-frequency, 200 GHz signals through a pair of copper wires. The result is a link that can move data at rates of terabits per second, significantly faster than currently available channels. In Applied Physics Letters, the scientists discuss their work using experimental measurements and mathematical modeling to characterize the input and output signals in a waveguide.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have used machine learning to study spin models, used in physics to study phase transitions. Previous work showed that image/handwriting classifying AI could be applied to distinguish states in the simplest models. The team showed the approach is applicable to more complex models and found that an AI trained on one model and applied to another could reveal key similarities between distinct phases in different systems.
Researchers have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health.
Scientists create model to measure how cells sense their surroundings.
Two Iowa State engineers, who announced the solution to a 50-year-old puzzle in signal processing last fall, have followed up with more research results. The engineers say their new algorithm is more useful and just as fast as the one previously used.
Usain Bolt's 200m record has not been beaten for ten years and Florence Griffith Joyner's for more than thirty years. And what about if the secret behind beating records was to use mathematics? Thanks to a mathematical model, french researchers have proved that the geometry of athletic tracks could be optimised to improve records. They recommend to build shorter straights and larger radii in the future.
New modelling research, published in The Lancet Public Health journal, suggests that school and workplace closures in Wuhan, China have reduced the number of COVID-19 cases and substantially delayed the epidemic peak -- giving the health system the time and opportunity to expand and respond.
Belying their slimy natures, the sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Now, researchers at Princeton University have combined expertise in molecular biology, mechanical engineering and mathematical modeling to unravel the physical processes underlying these curious crinkles.
