A demonstration of a fire escape chute on the streets of Daegu, South Korea. An escape chute is a special kind of emergency exit, used where conventional fire escape stairways are impractical. The chute is a fabric (or occasionally metal) tube installed near a special exit on an upper floor or roof of a building, or a tall structure.
The narrow escape problem [1] [2] is a ubiquitous problem in biology, biophysics and cellular biology. The mathematical formulation is the following: 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.
Escape reflex, or escape behavior, is any kind of escape response found in an animal when it is presented with an unwanted stimulus. [1] It is a simple reflectory reaction in response to stimuli indicative of danger, that initiates an escape motion of an animal. The escape response has been found to be processed in the telencephalon. [2]
A C-start is a type of a very quick startle or escape reflex that is employed by fish and amphibians (including larval frogs and toads). There are two sequential stages in the C-start: first, the head rotates about the center of mass towards the direction of future escape, and the body of the animal exhibits a curvature that resembles a letter C; then, at the second stage, the animal is ...
Chute (gravity), a channel down which falling materials are guided; Chute (landform), a steep-sided passage through which water flows rapidly; Escape chute, an emergency exit utilized where conventional fire escapes are impractical; Mail chute, a letter collection device
RNA folding problem: Is it possible to accurately predict the secondary, tertiary and quaternary structure of a polyribonucleic acid sequence based on its sequence and environment? Protein design : Is it possible to design highly active enzymes de novo for any desired reaction?
For example, herbivores can develop an adaptation that allows for improved detoxification which allow to overcome plant defenses, thus causing escape and radiate coevolution to continue. Often the term "evolutionary arms race" is used to illustrate the idea that continuous evolution is needed to maintain the same relative fitness while the two ...
Escape response in Antarctic krill.. Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation.It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator.
