For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology.
To walk or run with finesse, roaches and robots coordinate leg movements via signals sent through centralized systems. Though their moving parts are utterly divergent, researchers have devised handy principles and equations to assess how both beasts and bots locomote and to improve robotic gait.
Quantum mechanics boasts all sorts of strange features, one being quantum superposition -- the peculiar circumstance in which particles seem to be in two or more places or states at once. Now, an international group of physicists led by Stevens Institute of Technology flip that description on its head, showing that particles are not the only objects that can exist in a state of superposition -- so can time itself.
A team of scientists from School of Engineering at Far Eastern Federal University (FEFU), Institute of Automation and Control Processes, and Institute of Marine Technology Problems of the Far Eastern Department of the Russian Academy of Sciences developed a software module to automatically diagnose defects in sensors and electric drives in various kinds of robots. The system is able to compensate for the detected defects in real time.
By combining cutting-edge machine learning with 19th-century mathematics, a Worcester Polytechnic Institute (WPI) mathematician is working to make NASA spacecraft lighter and more damage tolerant by developing methods to detect imperfections in carbon nanomaterials used to make composite rocket fuel tanks and other spacecraft structures.
It is among the most spectacular events in the universe: a merger of neutron stars. An international team of researchers with strong representation from the Technical University of Munich (TUM) has completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.
A team of neuroscientists at the University of Tuebingen and MIT's Picower Institute for Learning and Memory shows how to distinguish four classes of brain cells by their spike waveforms. The advance offers brain researchers the chance to better understand how different kinds of neurons are contributing to behavior, perception and memory, and how they are malfunctioning in cases of psychiatric or neurological diseases.
Cultural processes are increasingly short-lived, showing in addition a growing tendency toward self-organisation. As a result, success is now governed by a universal law. This was discovered by the physicists Professor Claudius Gros and Lukas Schneider from Goethe University. Their object of research: 50 years of music charts.
Researchers at the George Washington University have developed a mapping model, the first of its kind, to track how hate spreads online.
Speeding is the riskiest kind of aggressive driving, according to a unique analysis of data from on-board devices in vehicles.
