Researchers have developed a new method -- 'Pixel Approximate Entropy' -- that measures the complexity of a data visualization and can be used to develop easier to read visualizations. 'In fast-paced settings, it is important to know if the visualization is going to be so complex that the signals may be obscured. The ability to quantify complexity is the first step towards automatically doing something about this.'
Through a collaborative research effort, an Army researcher has made a novel contribution to cloud security and the management of cyberspace risks.
Researchers at the University of Jyväskylä have taken part in an international British-Finnish-Chinese collaboration where the first molecule capable of remembering the direction of a magnetic above liquid nitrogen temperatures has been prepared and characterized. The results may be used in the future to massively increase the storage capacity of hard disks without increasing their physical size.
Based on an analysis of data leakages and opportunities to prevent the potential misuse of genetic information, researchers have developed a new file format for functional genomics data that enables data sharing while protecting the personal information of research participants. The findings were presented at the American Society of Human Genetics (ASHG) 2018 Annual Meeting in San Diego, Calif.
Researchers from MIT and Massachusetts General Hospital have developed an automated model that assesses dense breast tissue in mammograms -- which is an independent risk factor for breast cancer -- as reliably as expert radiologists. This marks the first time a deep-learning model of its kind has successfully been used in a clinic on real patients, according to the researchers. With broad implementation, the researchers hope the model can help bring greater reliability to breast density assessments across the nation.
New algorithms take advantage of multiple smart watch sensors to accurately monitor wearers' sleep patterns. As well as obtaining rich information on wearers' sleep, the software, called SleepGuard, can estimate sleep quality and provide users with practical advice to help them get a better night's snooze.
Scientists from EPFL and ETH Zurich have developed an ultra-light glove -- weighing less than 8 grams per finger- that enables users to feel and manipulate virtual objects. Their system provides extremely realistic haptic feedback and could run on a battery, allowing for unparalleled freedom of movement.
A battery-free energy harvester, a novel conductive system for smartwatches, and a prototype that extends body language to the human ear feature at new tech conference.
Engineers at MIT have developed an algorithm that quickly pinpoints the types of extreme events that are likely to occur in a complex system, such as an ocean environment, where waves of varying magnitudes, lengths, and heights can create stress and pressure on a ship or offshore platform. The researchers can simulate the forces and stresses that extreme events -- in the form of waves -- may generate on a particular structure.
Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) came closer to solving one of the key issues of offshore oil production, namely they developed a special method of nondestructive testing of drilling rig elements in the oil wells, which will ensure the efficient oil production and reduce the time and cost of equipment repair.
