» New theory finds 'traffic jams' in jet stream cause abnormal weather patterns
Thu, 24 May 2018 14:16:47 EDT
A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.
» Dengue: Investigating antibodies to identify at-risk individuals
Wed, 23 May 2018 13:33:52 EDT
Using an original mathematical and statistical analysis method, scientists analyzed a Thai cohort in order to help identify individuals at risk of infection. By modeling changes in antibody levels after successive infections with the different dengue serotypes, the scientists were able to establish the profile of these individuals.
» Physicists with green fingers estimate tree spanning rate in random networks
Tue, 22 May 2018 12:32:55 EDT
Scientists calculate the total number of spanning trees in randomly expanding networks. This method can be applied to modelling scale-free network models, which, as it turns out, are characterized by small-world properties.
» Driverless cars change lanes more like humans do
Tue, 22 May 2018 11:48:29 EDT
Researchers 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.
