The rules of the railway still cover mechanical signals, which have all but disappeared.

They speculate that the channels convert a host of other mechanical signals as well.

Their primary function is mechano-transduction, or conversion between mechanical and neural signals.

Outer hair cells on the other hand boost the mechanical signal by using electromechanical feedback.

A major challenge in the field is understanding mechanotransduction-the molecular mechanism by which cells sense and respond to mechanical signals.

It took a second for her brain to process the mechanical signal.

Fixed mechanical signals began to replace hand signals from the 1830s.

It is well known that a wide-variety of cell types change their behavior to mechanical environmental signals.

What horrible sort of mechanical signal was that that dazzled a sense beyond sight?

It took Jason a moment to realize that it was a mechanical signal, not a human voice.
