DOI: 10.1021/acsnano.2c08325 Many flexible fitness trackers can't be submerged in water because the coatings required to completely seal these devices would...

Credit: Pixabay/CC0 Public Domain Inertial sensors such as accelerometers and gyroscopes are used nearly everywhere, from smartwatches to submarines, drones, spacecraft, vacuum cleaners and even game controllers. The purpose of these sensors is to indicate the position, speed or direction of an object. Their drawback is their lack of precision,...

New US measures to limit China's access to high-end semiconductors have hammered the share prices of chip makers including Taiwan's TSMC. Chipmakers plunged in Asian trade Tuesday over new US measures to limit China's access to high-end semiconductors with military uses, a move that wiped billions from companies' valuations worldwide....

This revolutionary mouthguard – a first-of-its-kind bite-controlled optoelectronic system - invented by researchers from the National University of Singapore is affordable, light-weight, compact, and requires less training time compared to existing assistive technologies.

Qubit layout for implementing two Fermi-Hubbard instances. (a) 1 × 8 instance, (b) 2 × 4 instance. In each case two qubits are used to encode each site. Operations between qubits in variational layers occur in the following pattern. 1 × 8: blue (FSWAP), red (onsite), blue (FSWAP), red (vert1), green (vert2). 2 × 4: blue (FSWAP), red...
