New research in the INFORMS journal Operations Research has found a way to identify extremists, such as those associated with the terrorist group ISIS, by monitoring their social media accounts, and can identify them even before they post threatening content.
Semiautomatic rifles, which have been used in some of the largest shootings by individuals in US history, were banned in 1994 under the federal assault weapons ban, but that expired in 2004. This study compared the number of people wounded and killed during active shooter incidents (defined by the FBI as an individual killing or attempting to kill people in a confined or populated area) with, and without, semiautomatic rifles from 2000 through 2017.
New plume dispersal model alerts authorities how much time people have to flee after an attack.
According to new study of Syrian War in INFORMS journal Operations Research, unless there is a player so strong it can guarantee a win regardless of what others do, the likely outcome of multilateral war is a gradual stalemate that leads to mutual annihilation of all players.
First responders to major chemical exposure incidents in the United States can improve treatment protocols for at-risk casualties with better communication strategies, according to new analysis in Annals of Emergency Medicine.
New estimates published in The Lancet suggest that armed conflicts across the continent of Africa may have resulted in the deaths of as many as 5 million children aged under 5 years between 1995 and 2015, and claimed the lives of over 3 million infants aged one year or younger -- a burden several times higher than previous estimates.
Writing in advance of the Sept. 15 issue of Neural Computation, Beatrice Golomb, M.D., Ph.D., professor of medicine at University of California San Diego School of Medicine, says publicly reported symptoms and experiences of a 'mystery illness' afflicting American and Canadian diplomats in Cuba and China strongly match known effects of pulsed radiofrequency/microwave electromagnetic (RF/MW) radiation.
Researchers from the University of Texas at San Antonio used computer models on the Stampede2 supercomputer to replicate the dispersal of gases from the April 4, 2017 chemical weapons attack in northwest Syria. The simulations were able to capture real world conditions despite a scarcity of information. Recently, the team developed a coarse model that uses seasonal conditions as background information to speed up calculations, reducing forecasting time from days to minutes.
Once in the territory of science fiction, 'nanobots' are closer than ever to becoming a reality, with possible applications in medicine, manufacturing, robotics and fluidics. Today, scientists report progress in developing the tiny machines: They have made nanobot pumps that destroy nerve agents, while simultaneously administering an antidote. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Army researchers have designed a computer model that more effectively calculates the behavior of atmospheric turbulence in complex environments, including cities, forests, deserts and mountainous regions.
