UCLA researchers and colleagues who analyzed electronic health records found that there was a 50% increase in patients with coughs and acute respiratory failure at UCLA Health hospitals and clinics beginning in late December 2019 and continuing into February, suggesting that COVID-19 may have been circulating in the area months before the first definitive cases in the U.S. were identified.
HSE University economists analyzed two data sets for Russian regions in 2010-2016: the official statistics of the Russian Statistics Agency on alcohol sales and estimates of unregistered alcohol consumption modeled by the study's authors relying on the Ministry of Health's own methodology. It appeared to be that, despite a steady decline in alcohol consumption in the country, it varies greatly from region to region (from 1.1 up to 17-20+ liters of pure alcohol per adult).
In the paper, 'How directed is a directed network?', published today, the 9th September in the journal Royal Society Open Science, researchers from the University of Warwick and the University of Birmingham reveal a new method for analysing hierarchies in complex networks and illustrate it by applications to economics, language and gene expression.
A recent study by a team based at the University of Bologna, published in the Journal of Archaeological Science, has shed new light on the Minoan system of fractions, one of the outstanding enigmas tied to the ancient writing of numbers.
A recent study by sport analytics professors shows the Adjusted Plus-Minus (APM) statistic used to evaluate the performance of NBA players is sometimes misleading because it does not accurately account for the quality of a player's teammates.

When you only have fossils to go off of, it's hard to tell which dinosaur traits, like size and ornamentation, are related to the animals' sex, and which traits are related to other things like age. But a new kind of statistical analysis can often estimate the degree of sexual variation in a dataset of fossils.
CATONSVILLE, MD, August 11, 2020 - The Transportation Security Administration (TSA) has reported that it found 4,432 firearms in carry-on baggage at airport security checkpoints in 2019, and more than 20,000 firearms since 2014. New research published in the INFORMS Journal on Applied Analytics suggests that they could have found even more.
Consider this scenario: A vaccine for the novel coronavirus has been developed that is 91.27% effective. If public health officials present this information using the specific number, people are likely to think the vaccine is actually less effective than if it is presented as being 90% effective. This concept is a real-life application of recent findings from Gaurav Jain, an assistant professor of marketing in the Lally School of Management at Rensselaer Polytechnic Institute, published recently in Organizational Behavior and Human Decision Process.
For smokers who are better at math, the decision to quit just adds up, a new study suggests. Researchers found that smokers who scored higher on a test of math ability were more likely than others to say they intended to quit smoking.
