Researchers from Predictive Science Inc. used NASA and National Science Foundation-supported supercomputers to run highly-detailed forecasts of the Sun's corona -- the aura of plasma that surrounds the sun -- at the moment of the eclipse. The team combined data from NASA's Solar Dynamics Observatory, magnetic field maps, solar rotation rates and cutting-edge mathematical models to predict the state of the Sun's surface. The simulations are the largest produced by the group and include new physics.
A research team from Predictive Science Inc. (PSI) used the Stampede2 supercomputer at The University of Texas at Austin's Texas Advanced Computing Center (TACC) to forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.
An international team of scientists, led by mathematicians from the University of Exeter's Living Systems Institute, have developed a ground-breaking new method that can identify regions of brain tissue most likely to generate seizures in people with epilepsy.
Scientists have developed a new way to detect which areas of the brain contribute most greatly to epilepsy seizures, according to a PLOS Computational Biology study. The strategy, devised by Marinho Lopes of the University of Exeter and colleagues, could help surgeons select specific brain areas for removal to stop seizures.
Treatment of tuberculosis involves a combination of several drugs, sometimes including drugs from a class known as fluoroquinolones. Using computer simulations, scientists have shown that the fluoroquinolone known as moxifloxacin may be superior to two other commonly used fluoroquinolones, according to a new paper in PLOS Computational Biology.
A team of university researchers has devised the first automated techniques to identify ads potentially tied to human trafficking rings and link them to public information from Bitcoin -- the primary payment method for online sex ads. They found they could identify groups of ads with a common author. They then tested an automated system that utilizes publicly available information from the Bitcoin mempool and blockchain to find connections between ads.
A human being's psychological make-up depends on an array of emotional and motivational parameters. It includes spatial and temporal dimensions that also play a key role in rationalizing the decisions we make. Researchers from UNIGE, Texas, Paris and London joined forces to create a mathematical model of embodied consciousness. Their aim? To understand, study and predict human behavior. The model makes it possible to anticipate and explain a host of cognitive phenomena and behavioral reactions.
Small formats like Save-A-Lot and Aldi and neighborhood stores like Target Express have been growing recently in popularity in the US and around the world. For brands, the limited assortments mean greater competition for shelf-space, raising the question of whether it is worth expending marketing effort and slotting allowances to get on to their shelves. According to a forthcoming study in a leading INFORMS scholarly marketing journal, Marketing Science, the answer is 'yes.'
Hall thrusters are used in earth-orbiting satellites and show promise to propel robotic spacecraft long distances, and the plasma ejected from the exhaust end of the thruster can deliver great speeds. Cylindrical Hall thrusters lend themselves to miniaturization and have a smaller surface-to-volume ratio that prevents erosion of the thruster channel. Investigators in China have developed a new design for CHTs that significantly increases thrust; they report their work in this week's Physics of Plasmas.
A 'Frankenstein's monster' dinosaur may be the missing link between two major dinosaur groups, plugging what was previously a big gap between them.
