Researchers have developed a statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolutionary history of related languages. Their model gives researchers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors — potentially thousands of years further into prehistory than previous techniques.
Engineers at Oregon State University have completed one of the most precise evaluations yet done about the impact of a major tsunami event on the Columbia River, what forces are most important in controlling water flow and what areas might be inundated.
A new mathematical analysis tool has allowed a deeper understanding of the anatomy of the human head, describing the skull as an extended network structured in 10 modules. Researchers have developed a research methodology called Anatomical Network Analysis (AnNA), based on network analysis mathematical tools for studying anatomy.
To bring facts and clarity to the public debate about immunization in light of the recent measles outbreak, the University of Pittsburgh Graduate School of Public Health unveiled a computer simulation that explores the impact of measles outbreaks in cities across the U.S. Users can see how an outbreak would play out if their city had high or low vaccination rates.
During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions “driven primarily” by human-induced global warming, a new study predicts. The research says the drying would surpass in severity any of the decades-long “megadroughts” that occurred much earlier during the past 1,000 years.
Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.
A hurricane is heading toward the coast. Weather forecasters predict strong winds, massive waves and intense rainfall. But what does that mean for you? Will your neighborhood be flooded? Should you evacuate?
The author of this wonderful text delivers a brief, easy-to-absorb, yet very comprehensive text on modeling real-world data with Maple. Maple is software for performing mathematics, with a none-too-steep learning curve. In the introduction, the author is quick to point out that this is neither a detailed textbook of mathematical modeling, nor Maple. It is, however, a very well-written manual of introductory modeling and use of Maple.
A new online resource will help coastguards, meteorological organizations and scientific communities predict future storm surge patterns. The freely-accessible database has been compiled through the multi-partner, international eSurge project, which was launched in 2011 with the aim of making available observational data to improve the modeling and forecasting of storm surges around the world using advanced techniques and instruments.
For Paul Torrens, wintry weather is less about sledding and more about testing out models of human behavior. Torrens, a geographer at the University of Maryland, studies how snow and icy conditions affect human decisions about transportation. He also studies how these decisions ripple through other infrastructure systems.
Top researchers are using mathematical modelling and heavy computations to understand how the brain can both remember and learn. Ten years ago, when the team of Marianne Fyhn and Torkel Hafting Fyhn cooperated with the Nobel Prize winning team of May-Britt and Edvard Moser at NTNU, they discovered the sense of orientation in the brain.
Researchers have cracked a code that governs infections by a major group of viruses, including the common cold and polio. The unnoticed code had been hidden in plain sight in the sequence of the ribonucleic acid (RNA) that makes up this type of viral genome. But researchers have unlocked its meaning and demonstrated that jamming the code can disrupt virus assembly. Stopping a virus assembling can stop it functioning.
Farmers have long noted a correlation between rainstorms and disease outbreaks among plants. Fungal parasites known as “rust” can grow particularly rampant following rain events, eating away at the leaves of wheat and potentially depleting crop harvests. While historical weather records suggest that rainfall may scatter rust and other pathogens throughout a plant population, the mechanism by which this occurs has not been explored.
Researchers say they can predict the spread of flu a week into the future with as much accuracy as Google Flu Trends can display levels of infection right now. The study uses social network analysis and combines the power of Google Flu Trends’ big data with traditional flu monitoring data from the CDC.
If you were trying to forecast tomorrow's weather, you would probably look up at the sky rather than down at the ground. But if you live in the U.S. Midwest or someplace with a similar climate, one key to a better weather forecast may lie beneath your feet. Better soil moisture observations lead to better land-atmosphere interaction in weather forecasting models and ultimately to a better prediction of temperature and precipitation.
A new search engine outperforms current ones, and helps people to do searches more efficiently. The SciNet search engine is different because it changes Internet searches into recognition tasks, by showing keywords related to the user’s search in topic radar. People using SciNet can get relevant and diverse search results faster, especially when they do not know exactly what they are looking for or how to formulate a query to find it.
Researchers were able to predict the interactions of cancer cells using a part of game theory known as the public goods game, suggesting that work on the social interactions among cancer cells may provide insight into the dynamics of cancer. Researchers applied this model to the cooperation between producing and non-producing members of a cancer cell population, in order to examine if the model is also applicable to biological processes.
NASA and NOAA have provided nighttime and daytime views of the Blizzard of 2015. A combination of the day-night band and high-resolution infrared imagery showed the historic blizzard near peak intensity as it moves over the New York through Boston Metropolitan areas at 1:45 a.m. EST on January 27, 2015. Nighttime lights of the region were blurred by high cloud tops associated with the most intense parts of the storm.
Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future. This allows scientists to determine the age of large swaths of the second largest mass of ice on Earth.
Scientists have taken a new path in the research into causes of epilepsy: They determined the networks of the active genes and — like a dragnet — looked for the "main perpetrators" using a computer model. In doing so, they discovered the molecule sestrin-3 as a central switch. In animal models, the scientists were able to demonstrate that inhibition of sestrin-3 leads to a reduction in seizures.
A new virtual reality system allows architects to view 3-D models of buildings in their intended shape, precisely where the buildings will be constructed. This provides a much clearer, realistic impression of the design. Digitization is fundamentally changing the work processes in architectural design, planning and construction work. Increasingly, CAD drawings are transferred to a central 3-D Building Information Model...
Wave equations help describe waves of light, sound and water as they occur in physics. Also known as partial differential equations, they have valuable potential for predicting weather or earthquakes, or certain types of natural disasters. Tao is interested in the theoretical side of these equations, seeking to discover with computer algorithms whether they can behave in a way that typically is the opposite of what occurs in the real world.
Researchers have found that, based on enough Facebook Likes, computers can judge your personality traits better than your friends, family and even your partner. Using a new algorithm, researchers have calculated the average number of Likes artificial intelligence (AI) needs to draw personality inferences about you as accurately as your partner or parents.
This is not a text for the novice. However, for those math/statistics aficionados, there is much to be had. The book’s great strength lies in two areas: the first is Peter Congdon’s generation of an excellent bibliography of the most modern techniques available, and the other is his (slightly) more straightforward explanations of the strengths and weaknesses of these techniques and suggestions for optimizing the results.
