The COVID-19 pandemic has made clear the importance of understanding precisely how diseases spread throughout networks of transportation. In a paper publishing on Thursday in the IAM Journal on Applied Mathematics, Stephen Kirkland (University of Manitoba), Zhisheng Shuai (University of Central Florida), P. van den Driessche (University of Victoria), and Xueying Wang (Washington State University) study the way in which changes in a network of multiple interconnected communities impact the ensuin...

This book explains general and specific types of subharmonic functions, related partial differential equations, mathematical proofs and extension results.

But how about civil engineering and city planning? How might machine- and deep-learning help us create safer, more sustainable, and resilient built envi...

Credit: Kazan Federal University Problems for eigenmodes of a two-layered dielectric microcavity have become widespread thanks to the research of A.I. Nosich, E.I. Smotrova, S.V. Boriskina and others since the beginning of the 21st century. The KFU team first tackled this topic in 2014; undergraduates started working under the guidance of Evgeny Karchevsky, Professor of the Department of Applied Mathematics of the Institute of Computational Mathematics and Information Technology. In this paper,...

Researchers at Chinas Qingdao University have developed a new multi-modal image fusion method based on supervised deep learning. It enhances image clarity, reduces redundant image features and supports batch processing, improving the accuracy of medical diagnoses.

 E-Mail CATONSVILLE, MD, May 4, 2021 - Paid video streaming services on your television, smart phone or other devices are increasingly replacing traditional video entertainment platforms of cable, satellite and broadcast TV. The growth of these services, known in the industry as over-the-top (OTT) media services, may be accompanied by a rise in pirated content, particularly where access to those services may be restricted, a group of researchers has found. The researchers studied the effects o...

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the vertical turbines increase each others performance by up to 15%.
