But the surface of a doughnut has complex, or nontrivial, topology (SN: 10/4/16). A loop that encircles the doughnut’s hole, for example, can’t be shrunk down, because the hole limits how far ...

We combine topology and active matter paradigms in an effort to achieve topology-dictated nonequilibrium self-assembly of topologically distinct active particles. Active colloids are a distinct ...

This effect stems from a nontrivial coupling between electron motion and spin within chiral structures, yet quantifying it remains challenging. To address this, researchers at the Institute for ...

Raja Krishnamoorthi (D-Ill.) weighed in on questions swirling around China’s potential use of drones against the U.S., claiming the chance was “nontrivial.” Krishnamoorthi, the top Democrat ...

Samuelson once regarded the principle of comparative advantage—the modern theory of the gains from trade—as nontrivial. I would go a little further and say it was the greatest gift that ...

Canada-based researchers have investigated the impact of transferring a COVID-19 vaccine manufacturing process between two similar-sized bioreactors. Juan Sebastian Reyes Davila, a PhD student ...
