New technology will allow important metals to be made more efficiently
metallic oxide thin film electronic components
2021/8/9
Researchers have invented a cheaper, safer, and simpler technology that will allow a 'stubborn' group of metals, such as the Pt-group elements, to be transformed into thin films for various practical ...
How do birds breathe so efficiently? Looped airways facilitate air flows（图）
birds breathe efficiently Looped airways facilitate air flows
2021/4/9
Birds breathe with greater efficiency than humans because of the structure of their lungs --looped airways that facilitate air flows that go in one direction -- a team of researchers has found. The re...

We give the first algorithm that is both query-efficient and time-efficient for testing whether an unknown function f : {0, 1}n → {−1, 1} is an s-sparse
GF(2) polynomial versus -far from every...
