Narrow Escape
The Narrow escape problem is a ubiquitous problem in biology, biophysics and cellular biology which has the following formulation: a Brownian particle (ion, molecule, or protein) is confined to a bounded domain (a compartment or a cell) by a reflecting boundary, except for a small window through which it can escape. The narrow escape problem is that of calculating the mean escape time. This time diverges as the window shrinks, thus rendering the calculation a singular perturbation problem.

Famous quotes containing the words narrow and/or escape:
““All day long from mid-day
We have talked in the one place,
All day long from shadowless noon
We have gone round and round
In the narrow theme of love
Like an old horse in a pound.””
—William Butler Yeats (1865–1939)
“The omnipotence of evil has never resulted in anything but fruitless efforts. Our thoughts always escape from whoever tries to smother them.”
