Washington State University researchers have developed a new assessment tool to gauge the risk that someone with a mental illness will commit a crime. It could also speed up long-delayed competency evaluations for people awaiting trial.
New research challenges the belief that touchscreens are worse input devices because they lack physical buttons. The reason is that key press timing in touchscreen input is unpredictable. When timing is made more predictable, performance improves. A research group at Aalto University, Finland, propose a new theory of computer input explaining for example why serious gamers avoid touchscreens and why playing a piano on a touchscreen is so awkward.
Studying the way that solitary hunters such as tigers, bears or sea turtles chase down their prey turns out to be very useful in understanding the interaction between individual white blood cells and colonies of bacteria. Reporting their results in the Journal of Physics A: Mathematical and Theoretical, researchers in Europe have created a numerical model that explores this behavior in more detail.
In an article published this month in the SIAM Journal on Imaging Sciences, authors Jiulong Liu, Xiaoqun Zhang, Bin Dong, Zuowei Shen, and Lixu Gu propose a video segmentation model to recognize ROI in ultrasounds.
To bridge the gap between projections of future sea-level rise and the need to prepare for it, a Princeton University researcher and collaborators developed a method that consolidates climate models and the range of opinions that leading scientists have about them into a single, consistent set of probabilities.
A computer algorithm that can tell whether you are happy or sad, angry or expressing almost any other emotion would be a boon to the games industry. New research published in the International Journal of Computational Vision and Robotics describes such a system that is almost 99 percent accurate.
What if a map of the brain could help us decode people's inner thoughts? Scientists at the University of California, Berkeley, have taken a step in that direction by building a 'semantic atlas' that shows in vivid colors and multiple dimensions how the human brain organizes language.
Scientists are teaching computers to figure out why people accept or decline invitations to participate in clinical trials. Recruiting sufficient numbers of participants is a current challenge in medical research that can compromise results or stop some studies altogether. Researchers at Cincinnati Children's Hospital Medical Center report April 27 in the Journal of the American Medical Informatics Association they are using so-called 'machine learning' technologies to predict whether patients will participate.
A machine-learning algorithm created by a A research team has created an algorithm that improves the accuracy of dating past events by a factor of up to 300. The mathematical research, led by two UWM physicists, is featured in the journal Nature.
Using a new model, three Washington State University researchers predict that many forests across the US are ill-suited to withstand drought conditions likely to face the country in the coming century. Furthermore, in the Pacific Northwest, and across much of the US southern border, conditions may well require the development of new forest types not currently seen in the US.
