In poetry:

But though they roused up beast and bird
From many a nest and den,
No signal of success was heard
From all the hundred men.
"The Child and the Hind" by Thomas Campbell
And even tho' we're never quit
Of these sharp earthly thorns,
In black despair we'll never sit,
Till danger's signal warns.
"Temptation" by Thomas Frederick Young
In the first watch of the night,
Without a signal's sound,
Out of the sea, mysteriously,
The fleet of Death rose all around.
"By The Seaside : Sir Humphrey Gilbert" by Henry Wadsworth Longfellow
And I think of the hands that signal
The hours there in the gloom,
And wonder what angel watchers
Wait in the darkened room.
"In The Dark" by James Whitcomb Riley
The antients gloried to describe,
And held such wonders dear;
For of the Psylli's signal tribe,
'Twas their delight to hear.

Round the dark horizon sweep
With thine eye—stern vigil keep;
Fresh storm-signals flash and quiver,
War and blood foretelling ever.

In science:

Wavelet transformations that preserve the local characteristics of a sparse signal can be regarded as “almost” sparse in the “frequency ” domain; in general, for sparse signals, the more similar the transformation matrix is to an identity matrix, the sparser the signal is in the transform domain.
A Unified Approach to Sparse Signal Processing
It is always the case, indeed it’s a commonplace, that measurements in classical signal processing that determine frequency distributions of a signal at a given time are not possible even for deterministic signals, so that, for example, Wigner functions are frequently used as time–frequency distributions.
Lie random fields
Using only these basic rules of signal propagation and signal reflection from barrier walls, signal delay (Fig. 10) and signal swapping (Fig. 11) tiles can be constructed.
Intrinsically universal n-dimensional quantum cellular automata
This signal interaction which induces a global phase change allows the definition of both a two signal controlled-R( π 4 ) tile (Fig. 13) and a single signal R( π 4 ) operation tile (Fig. 14).
Intrinsically universal n-dimensional quantum cellular automata
From this map, we can clearly identify three strong signals with the time of coalescence within the observational time and one weak signal with time of coalescence about 3 months after the end of observations (signals are pointed by arrows).
