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 ...

Researchers at Zhejiang University, University of Cambridge and other institutes recently showed that QLEDs exhibit an excitation-memory effect, which could help to improve their response speeds.

Fluorescence probes require external excitation light to shine. When external light shines on a tissue, every cell responds, creating a lot of background light that makes it harder to distinguish ...

As such, this neurotransmitter plays a crucial role in establishing the balance of excitation and inhibition in the brain. Any disruption in this balance can have a major impact on brain functions ...
