At the International Conference on Robotics and Automation, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) will present a new lane-change algorithm that splits the difference. It allows for more aggressive lane changes than the simple models do but relies only on immediate information about other vehicles' directions and velocities to make decisions.
It may sound like the stuff of fairy tales, but in the 1950s two numerical models initially developed as a pet project by physicists led to the birth of an entirely new field of physics: computational statistical mechanics. This story has recently appeared in a paper published in EPJ H, authored by Michel Mareschal, an Emeritus Professor of Physics at the Free University of Brussels, Belgium.
The tiniest of natural phenomena can have a big impact on our weather, but an international team of researchers have found that the most widely used system to model meteorological conditions doesn't account for environmental microphysics well at all scales.
Variation in expertise and risk-taking behaviors among investors regularly sends markets on roller-coaster rides. Researchers describe the intricate dynamics driving a financial markets model in this week's Chaos. Their model takes aim to simulate asset pricing when mixed groups of investors enter a market. By examining bifurcation conditions, they described transitions between different chaotic dynamical regimes. They showed that their model can reflect the nature of real markets by switching between bear and bull dynamics.
The blood of schizophrenia patients features genetic material from more types of microorganisms than that of people without the debilitating mental illness.
The hotter our body temperature, the more our bodies speed up a key defence system that fights against tumours, wounds or infections, new research by a multidisciplinary team of mathematicians and biologists from the Universities of Warwick and Manchester has found.
The study shows racial disparities in suicide rates are age-related. Specifically, suicide rates for black children aged 5-12 were roughly two times higher than those of similarly-aged white children. For older children, the trend reverses back to the national average. For youth aged 13-17 years, suicide was roughly 50 percent lower in black children than in white children.
A new algorithm developed by UCLA researchers more accurately predicts which people will survive heart failure, and for how long, whether or not they receive a heart transplant.
MIT engineers have developed a new virtual-reality training system for drones that enables a vehicle to 'see' a rich, virtual environment while flying in an empty physical space. The system, which the team has dubbed 'Flight Goggles,' could significantly reduce the number of crashes that drones experience in actual training sessions. It can also serve as a virtual testbed for any number of environments and conditions in which researchers might want to train fast-flying drones.
The sounds of amphibians are altered by the increase in ambient temperature, a phenomenon that, in addition to interfering with reproductive behaviour, serves as an indicator of global warming. Researchers at the University of Seville have resorted to artificial intelligence to create an automatic classifier of the thousands of frog and toad sounds that can be recorded in a natural environment.
