Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

We develop optimal sleeping and harvesting policies for radio frequency (RF) energy harvesting devices, formalizing the following intuition: when the ambient RF energy is low, devices consume more ...

Researchers at the University of California, Riverside, have uncovered how to manipulate electrical flow through crystalline ...

This paper proposes a coordinated ambient/ dedicated (CA/D) protocol where backscatter-enabled combination sensors are optimized to harvest energy from intended radio frequency (RF) sources when ...
