Sentences with phrase «vibrational signal»

A stop signal is a 300 — 400 Hz vibrational signal with a duration of approximately 150 ms [20,22] that a worker usually delivers while butting its head into the body of the receiver, causing the receiver to momentarily freeze [12,19,23,24].

Appel and Cocroft say future research will focus on how vibrations are sensed by the plants, what features of the complex vibrational signal are important, and how the mechanical vibrations interact with other forms of plant information to generate protective responses to pests.

By looking at the responses of closely related crickets, the scientists found the most likely origin for the female vibrational signal was a startle reflex seen in other crickets in response to loud high frequency sounds.

Instead, the females shake their whole body to produce a vibrational signal after each male call.

We call these vibrational signals «stop signals» because their general physical characteristics, fundamental frequency and duration, are similar to the stop signal of A. mellifera and because they elicited the same immediate response: receivers froze during signal delivery.

Not exact matches

In surface plasmon - enhanced vibrational spectroscopy, the recorded optical signals result from the interaction between molecular and plasmonic states.

The stop signal consists of a brief vibrational pulse that encodes information about the danger level in signal frequency and the danger context in signal duration.
