Defense scientists in China have discovered a way to make high-altitude drones more efficient using plasma excitation ...

The last decade has brought a new way to explore the universe. Gravitational wave astronomy, made possible by observatories ...

The light of someone's life might not be just another person, but light in the literal sense. According to a recent study by ...

To make a working nervous system, only two forces are necessary: excitation and inhibition. Excitatory signaling from one cell to the next makes the latter cell more likely to fire. Inhibitory ...

LIS Technologies (LIST), the US startup working on a novel laser-based approach to uranium enrichment, says it has raised another $12 million in funding - said to be its third consecutive ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

From this procedure we are able to see that the response of the building is dominated by the jth mode when the frequency of excitation is tuned to near the jth natural frequency. Shown below are ...
