Stimulating resonance with two very different forces

Widely studied in many different fields, 'nonlinear' systems can display excessively dramatic responses when the forces which cause them to vibrate are changed. Some of these systems are sensitive to changes in the very parameters ...

Simple model captures almost 100 years of measles dynamics in London

A simple epidemiological model accurately captures long-term measles transmission dynamics in London, including major perturbations triggered by historical events. Alexander Becker of Princeton University in New Jersey, U.S., ...

Certifying attack resistance of convolutional neural networks

When shopping for a watch, you may notice its water resistance rating, which indicates that the watch is warranted to be waterproof to a certain level. What about your neural network? Can one ensure a neural network is "attack ...

Diamond capsules improve performance of laser fusion

Osaka University-led researchers demonstrated that the perturbation of laser imprinting on a capsule for nuclear fusion fuel made from stiff and heavy materials was mitigated. Using the latest chemical vapor deposition (CVD) ...

When deep learning mistakes a coffee maker for a cobra

Is this your sister?" That's the kind of question asked by image-recognition systems, which are becoming increasingly prevalent in our everyday devices. They may soon be used for tumor detection and genomics, too. These systems ...
