With revenue from college football at an unprecedented $3.4 billion annually, universities across the country invest millions each year in recruitment efforts for high school football players. But with talented players typically receiving multiple scholarship offers, team rosters are in limbo until student athletes commit to a university. However, a new study in the INFORMS journal Decision Analysis shares how social media can provide universities with valuable insight into the decision-making process of their recruits.
A group of mathematicians has proved László Fejes Tóth's zone conjecture. For more than 40 years, mathematicians in the field of discrete and combinatorial geometry were trying to prove the theorem. Finally, a Chinese-Russian tandem managed to do that. The proof, published in the journal Geometric and Functional Analysis, is important for discrete geometry and enables new problems to be formulated.
A study publishing Dec. 12 in the open-access journal PLOS Biology by Johanna Espin, Emilio Bruna, and colleagues at the University of Florida finds that while scientists from an increasing number of countries are represented in the scientific journals in which scientists report their results, the editors of these journals are a far less diverse group.
While a strong infrastructure is important for healthcare, measures of health facility infrastructure are poorly correlated with health system quality, according to a new study published this week in PLOS Medicine by Hannah Leslie from the Harvard T.H. Chan School of Public Health, USA, and colleagues.
Few people draw a parallel between bumblebees and travelling salesmen but that's what comes after months of tracking the flight paths of the foraging pollinators as they refine their routes around multiple destinations and, in the process, provide insights into analogous problems in logistics and robotics and into how land might be used more efficiently.
Researchers from the University of Texas at Austin and the City of Austin have developed a tool that uses artificial intelligence to recognize objects in raw traffic camera footage and characterize how those objects move and interact. This information can then be analyzed and queried by traffic engineers and officials to improve the safety and performance of the city's transportation network. The work will be presented at the IEEE Big Data conference this week.
As state voter identification (ID) laws across the country are being contested amid questions about the integrity of the voting process, researchers have developed a new statistical method that not only matches multiple records with precision, but can also identify the scope of discrimination when applied to voter ID laws.
The best decisions are made on the basis of the average of various estimates: this has been confirmed by the research of Dennie van Dolder and Martijn van den Assem, scientists at VU Amsterdam. Using data from Holland Casino promotional campaigns, they have researched whether it is true that when people make estimates, the average of their estimates is relatively close to reality. The results of the research are being published today in Nature Human Behaviour.
Three billion years ago, the sun shone weaker, but Earth stayed surprisingly warm. Carl Sagan thought a greenhouse effect must have been to thank. A model built on 359 chemical processes has finally arrived at scenarios with a reasonable chance of producing the needed methane on ancient Earth. The model has broad parameters in hope that it may someday be of use to interpret conditions on exoplanets.
University of Leeds researchers have mathematically examined plasma jets from supermassive black holes to determine why certain types of jets disintegrate into huge plumes.
