There are currently more than three million people in the US with hepatitis C, a condition that can lead to serious and even deadly liver complications. In the US prison system, the prevalence of hepatitis C virus (HCV) infection is currently 10 times higher than the national average. However, new research in the INFORMS journal Operations Research, has identified new protocols that could substantially decrease HCV infection in the US prison system.
Scientists have known about the existence of the hydrated electron -- extra electrons solvated in liquid water -- for more than fifty years. They haven't been too sure of its structure though. MARVEL researchers at the University of Zurich, ETH and the Swiss National Supercomputing Center CSCS have now taken a huge step towards solving the mystery. Their paper, 'Dynamics of the Bulk Hydrated Electron from Many Body Wave Function Theory,' has been published as a Very Important Paper in Angewandte Chemie.
Researchers from Northwestern University and Facebook in March published new research in the INFORMS journal Marketing Science that sheds light on whether common approaches for online advertising measurement are as reliable and accurate as the 'gold standard' of large-scale, randomized experiments.
High performance computing has revealed in detail how liquid droplets combine, in a development with applications such as improving 3D printing technologies or the forecasting of thunderstorms.
Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems - but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories. An international collaboration from Japan and Massachusetts unveiled an improved algorithm to track motor performance and speed estimation. Experiments demonstrate the potential effectiveness and advantages of the proposed algorithm: fast speed estimation transient and ease of tuning.
A report out today examines the factors that influence 'math anxiety' among primary and secondary school students, showing that teachers and parents may inadvertently play a role in a child's development of the condition, and that girls tend to be more affected than boys.
EPFL scientists have developed a new image-processing method that can capture extremely rapid phenomena using any type of camera. Their method, called Virtual Frame Technique, delivers better performance than any commercial high-speed camera and is affordable and accessible to anyone.
An international collaboration including scientists at the Department of Energy's Oak Ridge National Laboratory solved a 50-year-old puzzle that explains why beta decays of atomic nuclei are slower than what is expected based on the beta decays of free neutrons. The findings, published in Nature Physics, fill a longstanding gap in physicists' understanding of beta decay, an important process stars use to create heavier elements, and emphasize the need to include subtle effects--or more realistic physics--when predicting certain nuclear processes.
Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review demonstrating it's possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.
New technology developed by a Washington State University scientist could help police officers predict where burglaries are likely to occur.
