| random walk | <cell biology> A description of the path followed by a cell or particle when there is no bias in movement. The direction of movement at any instant is not influenced by the direction of travel in the preceding period. If changes of direction are very frequent, then the displacement will be small, unless the speed is very great and the object will appear to vibrate on the spot. Although the behaviour of moving cells in a uniform environment can be described as a random walk in the long term, this is not true in the short term because of persistence. (18 Nov 1997) |

Manner of walking; gait; step; as, we often know a person at a distance by his walk. 4. That in or through which one walks; place or distance walked over; a place for walking; a path or avenue prepared for foot passengers, or for taking air and exercise; way; road; hence, a place or region in which animals may graze; place of wandering; range; as, a sheep walk.

To move along on foot; to advance by steps; to go on at a moderate pace; specifically, of two-legged creatures, to proceed at a slower or faster rate, but without running, or lifting one foot entirely before the other touches the ground. "At the end of twelve months, he walked in the palace of the kingdom of Babylon." (Dan. Iv. 29) "When Peter was come down out of the ship, he walked on the water, to go to Jesus." (Matt. Xiv. 29) In the walk of quadrupeds, there are always two, and for a brief space there are three, feet on the ground at once, but never four. 2. To move or go on the feet for exercise or amusement; to take one's exercise; to ramble. 3. To be stirring; to be abroad; to go restlessly about; said of things or persons expected to remain quiet, as a sleeping person, or the spirit of a dead person; to go about as a somnambulist or a specter. "I have heard, but not believed, the spirits of the dead May walk again." (Shak) "When was it she last walked?" (Shak) 4. To be in motion; to act; to move; to wag. "Her tongue did walk in foul reproach." "Do you think I'd walk in any plot?" (B. Jonson) "I heard a pen walking in the chimney behind the cloth." (Latimer) 5. To behave; to pursue a course of life; to conduct one's self. "We walk perversely with God, and he will walk crookedly toward us." (Jer. Taylor) 6. To move off; to depart. "He will make their cows and garrans to walk." (Spenser) To walk in, to go in; to enter, as into a house. To walk after the flesh, to live in obedience to his commands, and have communion with him. Origin: OE. Walken, probably from AS. Wealcan to roll, turn, revolve, akin to D. Walken to felt hats, to work a hat, G. Walken to full, OHG. Walchan to beat, to full, Icel. Valka to roll, to stamp, Sw. Valka to full, to roll, Dan. Valke to full; cf. Skr. Valg to spring; but cf. Also AS. Weallian to roam, ramble, G. Wallen. Source: Websters Dictionary (01 Mar 1998) |

| walk-through angina | A circumstance in which despite continuing activity, such as walking, the pain of angina pectoris diminishes or disappears. (05 Mar 2000) |
| random | 1. Force; violence. "For courageously the two kings newly fought with great random and force." (E. Hall) 2. A roving motion; course without definite direction; want of direction, rule, or method; hazard; chance; commonly used in the phrase at random, that is, without a settled point of direction; at hazard. "Counsels, when they fly At random, sometimes hit most happily." (Herrick) "O, many a shaft, at random sent, Finds mark the archer little meant !" (Sir W. Scott) 3. Distance to which a missile is cast; range; reach; as, the random of a rifle ball. 4. <chemical> The direction of a rake-vein. Origin: OE. Randon, OF. Randon force, violence, rapidity, a randon, de randon, violently, suddenly, rapidly, prob. Of German origin; cf. G. Rand edge, border, OHG. Rant shield, edge of a shield, akin to E. Rand, n. See Rand. Going at random or by chance; done or made at hazard, or without settled direction, aim, or purpose; hazarded without previous calculation; left to chance; haphazard; as, a random guess. "Some random truths he can impart." (Wordsworth) "So sharp a spur to the lazy, and so strong a bridle to the random."

| random allocation | A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects. (12 Dec 1998) |
| random amplification of polymorphic DNA | <molecular biology> A term originally invented by polymer chemists to describe a disordered tangle of a linear polymer chain with curved sections. In DNA parlance the random coil refers to the structure that results from melting or other forms of separation of the double helix, i.e. Helix coil transition. (18 Nov 1997) |
| random amplified polymorphic DNA technique | Technique that utilises low-stringency polymerase chain reaction (pcr) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. Rapd technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes. (12 Dec 1998) |
| random coil | A structure of a macromolecule (typically, a biopolymer) which changes with time. (05 Mar 2000) |
| random mating | Totally haphazard mating with no regard to the genetic makeup (genotype) of the mate so that any sperm has an equal chance of fertilizing any egg. This rarely, if ever, occurs but the concept is impoortant in population genetics. Also called panmixus. (12 Dec 1998) |
| random mating equilibrium | <genetics> In a population containing the genotypes of AA, aa, and Aa, the frequency of AA will be p2, the frequency of aa will be q2, and the frequency of Aa will be 2 pq at equilibrium, where p is the frequency of A and q is the frequency of a. By the Hardy-Weinberg law, a ramdonly-mating population will eventually reach these frequencies and be at this equilibrium as long as there are no selection pressures on the population. (09 Oct 1997) |
| random mechanism | A scheme for substrate binding and product release for a multisubstrate enzyme; for a two-substrate two-product enzyme with this mechanism, either substrate can bind first and, after the reaction has taken place, either product can be the first to dissociate from the enzyme. Brain hexokinase has a random mechanism. More complex random mechanisms exist for enzymes having more than two substrates. (05 Mar 2000) |
| random pattern flap | A flap in which the pedicle blood supply is derived randomly from the network of vessels in the area, rather than from a single longitudinal artery as in an axial pattern flap. (05 Mar 2000) |
| random sample | A group selected randomly, solely by chance. (12 Dec 1998) |
| random sampling | A selection of elements by a formal randomizing device for purposes of inference about a population of inference from that population in such a way that the probability of each possible outcome may be precisely specified in advance; the inferences are necessarily stochastic. (05 Mar 2000) |
| random variable | A variable that may assume a set of values, each with fixed probabilities or probability densities (its distribution), in such a way that the total probability assigned to the distribution is unity; the random variable may be discrete, continuous, or mixed discrete-continuous. (05 Mar 2000) |
| random waves | Wave's in the electroencephalogram which occur paroxysmally and asynchronously. (05 Mar 2000) |
