Consumer stockpiling and hoarding took center stage in recent months as the COVID-19 virus has spread around the world, and with it, panic buying on the part of millions. News broadcasts and social media feeds have been filled with examples of the worst aspects of human nature.
Cryptocurrencies have been treated as a financial terra incognita -- they enjoyed growing interest but also raised concerns due to their virtuality. The use of statistical methods utilizing correlation matrices to analyze the hundred most-traded virtual currencies shows that the cryptocurrency market in the last two years is less and less different from the mature global currency market (Forex) and becomes independent of it. It means cryptocurrencies can be considered a serious and full-fledged financial instrument.
A joint research team from Toyohashi University of Technology has established a method to represent driving behaviors and their changes that differ among drivers in a single statistical model, taking into account the effect of various external factors such as road structure. This method was applied to measure the effectiveness of Intelligent Speed Adaptation (ISA), which controls excessive speed violations.
A precise statistical analysis reveals that on the Åland Islands a powdery mildew fungus that is a common parasite of the ribwort plantain primarily spreads via roadsides because traffic raises the spores found on roadsides efficiently into the air.
Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, Carnegie Mellon University researchers have pulled off the feat using video recorded on an ordinary smartphone. Shooting a continuous video of the front and sides of the face generates a dense cloud of data. A two-step process developed by CMU's Robotics Institute uses that data, with some help from deep learning algorithms, to build a digital reconstruction of the face.
By analyzing a century of data (1910 to 2010) in the American Film Institute Archive and the Internet Movie Database (IMDb), the researchers found that female representation in the film industry hit an all-time low during the so-called Golden Age.
A team of medical researchers and bioethicists at Oxford University has published results today in Science that furthers our understanding of coronavirus transmission. This evidence is enabling several international partners to assess the feasibility of developing mobile apps for instant contact tracing in record time. If rapidly and widely developed, these mobile apps could help to significantly slow the rate of transmission, and support countries to emerge from lockdowns safely, as restrictions are gradually eased.
With city contributions totaling $37 billion in 2018, or 6 percent of tax revenue, TRS has two important characteristics that distinguish it from most other public pension plans in the nation.
Using the same technology that allows high-frequency signals to travel on regular phone lines, researchers tested sending extremely high-frequency, 200 GHz signals through a pair of copper wires. The result is a link that can move data at rates of terabits per second, significantly faster than currently available channels. In Applied Physics Letters, the scientists discuss their work using experimental measurements and mathematical modeling to characterize the input and output signals in a waveguide.
The results suggest that sociologists and data scientists should use caution when using predictive modeling, especially in the criminal justice system and social programs.
