The expansion will contribute...

 E-Mail Texas A&M University researchers have designed a reinforcement-based algorithm that automates the process of predicting the properties of the underground environment, facilitating the accurate forecasting of oil and gas reserves. Within the Earths crust, layers of rock hold bountiful reservoirs of groundwater, oil and natural gas. Now, using machine learning, researchers at Texas A&M University have developed an algorithm that automates the process of determining key features of the Ea...

Scientists will monitor areas in which these diseases are endemic to investigate the factors that trigger outbreaks view more  Credit: CREATE-NEO By Maria Fernanda Ziegler | Agência FAPESP – Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to an understanding of how epidemics happen and should be combated. It was introduced to the Americas in the seventeenth century, and...

 E-Mail Graphs -- data structures that show the relationship among objects -- are highly versatile. Its easy to imagine a graph depicting a social media networks web of connections. But graphs are also used in programs as diverse as content recommendation (what to watch next on Netflix?) and navigation (whats the quickest route to the beach?). As Ajay Brahmakshatriya summarizes: "graphs are basically everywhere." Brahmakshatriya has developed software to more efficiently run graph application...

 E-Mail IMAGE: The spatial intensity profile of a laser beam propagating in a nonlinear medium spontaneously becomes nonuniform due to the process of modulational instability. view more  Credit: Institute for Basic Science We are most familiar with the four conventional phases of matter: solid, liquid, gas, and plasma. Changes between two phases, known as phase transitions, are marked by abrupt changes in material properties such as density. In recent decades a wide body of physics re...

 E-Mail PITTSBURGH--"The Queens Gambit," the recent TV mini-series about a chess master, may have stirred increased interest in chess, but a word to the wise: social media talk about game-piece colors could lead to misunderstandings, at least for hate-speech detection software. Thats what a pair of Carnegie Mellon University researchers suspect happened to Antonio Radi?, or "agadmator," a Croatian chess player who hosts a popular YouTube channel. Last June, his account was blocked for "harmful...

The study, co-led by G...

 E-Mail IMAGE: The studys findings suggest that decreasing hemispheric temperatures and associated ecological changes were the primary drivers of the Late Quaternary megafauna extinctions in North America. view more  Credit: Hans Sell A new study published in Nature Communications suggests that the extinction of North Americas largest mammals was not driven by overhunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based o...
