Neuron circuit may enable pitch perception applications

The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit operates according ...

2012 Great Plains drought not caused by climate change

From May to July 2012, the Great Plains region of the western United States faced a powerful and unpredicted drought. Following 7 months of normal rainfall, the drought was one of the largest deviations from seasonal precipitation ...

Founder of US-based Bose audio firm dies at 83

Acoustics pioneer Amar Bose, founder and chairman of the audio technology company Bose Corp., known for the rich sound of its small tabletop radios and its noise-canceling headphones popular among frequent fliers, has died ...

Random noise helps make signals clearer

Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), ...

Explained: Linear and nonlinear systems

Much scientific research across a range of disciplines tries to find linear approximations of nonlinear behaviors. But what does that mean?

Nonlinear thinker: Making sense of previously insoluble problems

If an airplane is cruising along and raises the flaps on its wings a degree or two, it will tilt upward. If it raises the flaps twice as much, it will tilt upward about twice as much. But if it tilts upward too far — generally ...

New Law of Physics Could Explain Quantum Mysteries

(PhysOrg.com) -- Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the observer’s role in measurements, ...
