Revamped crew scheduling model cuts airline delays by as much as 30%

Delays and disruptions in airline operations annually result in billions of dollars of additional costs to airlines, passengers and the economy. Airlines strive to mitigate these costs by creating schedules that are less likely to get disrupted or schedules that are easy to repair when there are disruptions — new research has found a solution using a mathematical optimization model.

Machine learning predicts behavior of biological circuits

Biomedical engineers have devised a machine learning approach to modeling the interactions between complex variables in engineered bacteria that would otherwise be too cumbersome to predict. Their algorithms are generalizable to many kinds of biological systems.

Why multipartite viruses infect plants rather than animals

Being in between living and non-living, viruses are, in general, strange. Among viruses, multipartite viruses are among the most peculiar — their genome is not packed into one, but many, particles. Multipartite viruses primarily infect plants rather than animals. A recent article uses mathematical and computational models to explain this observation.

Scientists finally find superconductivity in place they have been looking for decades

Scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern – as if hopping to the atom diagonally across the street rather than to the one next door.

Virtual human hand simulation holds promise for prosthetics

Animating human hands has long been considered one of the most challenging problems in computer graphics. That's because it has been impossible to capture the internal movement of the hand in motion — until now. Using magnetic resonance imaging (MRI) and a technique inspired by the visual effects industry, researchers have developed the world's most realistic model of the human hand's musculoskeletal system in motion. Applications include computer graphics, prosthetics, medical education, robotics, virtual reality.
