signaling

1. (American spelling) The sending of a signal (often with reference to a biochemical signal).Examples: "A lot of visual signaling happens on the deck of an aircraft carrier."; "The handkerchiefs were tied together, and ordering the men to stand between himself and the main body, he began a series of signalings, as if communicating with some one in the ravine, from whence they had just come."; "It arises as a consequence of the multiple interactions that occur after a ligand triggers a receptor to initiate a signaling cascade and it ensures that false signals do not propagate to completion."US
