The focal mechanism provides seismological constraints on the geological faults that generate the earthquakes and thus is important for regional seismotectonic research. Focal mechanism calculation ...

The monoalkylation of acetonitrile by primary alcohols was achieved in a one-pot sequence in the presence of iridium catalysts. A diversity of nitriles has been obtained from aryl- and alkyl-methanols ...

Key points Research has identified a broad ideological polarity that cuts across politics, morality, aesthetics, educational theory, and psychology. The existing polarity in thought and feeling ...

The bit-channel selection algorithms for polar codes and PAC codes are proposed, which take both utilization of the polarization effect and the ML decoding performance as selection criteria.

In the stratosphere over Siberia, temperatures recently jumped nearly 100 degrees Fahrenheit, shoving the polar vortex off its North Pole perch.

The Fish and Wildlife Service updated rules governing how much Arctic oil drilling can bother the Beaufort Sea’s protected polar bears.

With a 497-foot home run, Roman Anthony hit the farthest (and hardest) ball in all of baseball Saturday night. Oh, and it was also a grand slam.

Solvent structure and dynamics of acetonitrile at its liquid−vapor (LV) interface and at the acetonitrile−silica (LS) interface are studied by means of molecular dynamics simulations. We set up the ...
