Electrically connected spin-torque oscillators array for 2.4 GHz WiFi band transmission and energy harvesting


Researchers at the National University of Singapore and Tohoku University developed a device that uses spin-torque oscillators (STOs) to harvest energy from 2.4GHz Wi-Fi signals and wirelessly power an LED without need for a battery.   Technical Paper Link: Abstract "The mutual synchronization of spin-torque oscillators (STOs) is critical for communication, energy harvesting ... » read more

Emergent magnetic monopoles isolated using quantum-annealing computer


Using D-Wave’s quantum-annealing computer, Los Alamos National Laboratory has shown that it’s possible to isolate magnetic monopoles. This research could one day enable future nanomagnets.   Abstract: "Artificial spin ices are frustrated spin systems that can be engineered, wherein fine tuning of geometry and topology has allowed the design and characterization of exotic eme... » read more

Improving the Performance Of Deep Neural Networks


Source: North Carolina State University. Authors: Xilai Li, Wei Sun, and Tianfu Wu Abstract: "In state-of-the-art deep neural networks, both feature normalization and feature attention have become ubiquitous. They are usually studied as separate modules, however. In this paper, we propose a light-weight integration between the two schema and present Attentive Normalization (AN). Instead of l... » read more
