| gate-control hypothesis | A theory to explain the mechanism of pain; small fibre afferent stimuli, particularly pain, entering the substantia gelatinosa can be modulated by large fibre afferent stimuli and descending spinal pathways so that their transmission to ascending spinal pathways is blocked (gated). Synonym: gate-control hypothesis. (05 Mar 2000) |

| gate | 1. A way; a path; a road; a street (as in Highgate). "I was going to be an honest man; but the devil has this very day flung first a lawyer, and then a woman, in my gate." (Sir W. Scott) 2. Manner; gait. Origin: Icel. Gata; akin to SW. Gata street, lane, Dan. Gade, Goth. Gatwo, G. Gasse. Cf. Gate a door, Gait. 1. A large door or passageway in the wall of a city, of an inclosed field or place, or of a grand edifice, etc.; also, the movable structure of timber, metal, etc, by which the passage can be closed. 2. An opening for passage in any inclosing wall, fence, or barrier; or the suspended framework which closes or opens a passage. Also, figuratively, a means or way of entrance or of exit. "Knowest thou the way to Dover? Both stile and gate, horse way and footpath." (Shak) "Opening a gate for a long war." (Knolles) 3. A door, valve, or other device, for stopping the passage of water through a dam, lock, pipe, etc. 4. The places which command the entrances or access; hence, place of vantage; power; might. "The gates of hell shall not prevail against it." (Matt. Xvi. 18) 5. In a lock tumbler, the opening for the stump of the bolt to pass through or into. 6. The channel or opening through which metal is poured into the mold; the ingate. The waste piece of metal cast in the opening; a sprue or sullage piece. Alternative forms: geat and git] Gate chamber, a recess in the side wall of a canal lock, which receives the opened gate. Gate channel. See Gate. Gate hook, the hook-formed piece of a gate hinge. Gate money, entrance money for admission to an inclosure. Gate tender, one in charge of a gate, as at a railroad crossing. Gate valva, a stop valve for a pipe, having a sliding gate which affords a straight passageway when open. <anatomy> Gate vein, to enter a college inclosure after the hour to which a student has been restricted. To stand in the gate, or gates, to occupy places or advantage, power, or defense. Origin: OE. Et, eat, giat, gate, door, AS. Geat, gat, gate, door; akin to OS, D, & Icel. Gat opening, hole, and perh. To E. Gate a way, gait, and get, v. Cf. Gate a way in the wall, 3d Get. Source: Websters Dictionary (01 Mar 1998) |

| flap gate | <ecology, equipment> A device which allows water to flow in only one direction through a culvert, can be used to allow water to drain out of a wetland during low tide while preventing water from entering the wetland during high tide. (09 Oct 1997) |
| adaptor hypothesis | A hypothesis, proposed by F.H.C. Crick, that an adaptor molecule must be present between the information-containing DNA and the protein being synthesised. (05 Mar 2000) |
| altered self hypothesis | The hypothesis that the T-cell receptor in MHC mediated phenomena recognises a syngeneic MHC Class I or Class II molecule after modification by a virus or certain chemicals. See: MHC restriction. (18 Nov 1997) |
| alternative hypothesis | In Neyman-Pearson testing of a hypothesis, the hypothesis or family of hypotheses about the numerical value of a parameter if and only if the null hypothesis is rejected as untenable. (05 Mar 2000) |
| autocrine hypothesis | That tumour cells containing viral oncogenes may have encoded a growth factor, normally produced by other cell types, and thereby produce the factor autonomously, leading to uncontrolled proliferation. (05 Mar 2000) |
| Avogadro's hypothesis | <physics> The hypothesis that equal volumes of two different gases at the same temperature and pressure contain the same number of molecules. (02 Jan 1998) |
| Bayesian hypothesis | An array of surmised values of a parameter to be severally explored in the light of a current set of data, with logical symmetry being preserved among all. The merits of each hypothesis entertained are based on quantity, the prior probability. The probability of the data conditional on the hypothesis is computed as the conditional probability for each; the product of the two for each hypothesis is the joint probability, and the ratio of each joint probability to the sum of all the joint probabilities is the posterior probability for that hypothesis. Unlike the Neyman-Pearson test of hypotheses, the answer is a statement about the hypothesis, not about the sample conditional on the hypothesis. No hypothesis is preferred or prevails by default. The procedure may be applied recursively any number of times, as the data becomes available. (05 Mar 2000) |
| Makeham's hypothesis | A development of Gompertz' hypothesis as to the force of mortality following some mathematical law. Makeham assumed that death was the consequence of two generally coexisting causes: 1) chance; 2) a deterioration or increased inability to withstand destruction. The first of these is constant, the second is an increasing geometrical progression. (05 Mar 2000) |
| Gompertz' hypothesis | A theory that the force of mortality increases in geometrical progression, being based on the assumption that the average exhaustion of a person's power to avoid death is such that at the end of equal infinitely small intervals of time he loses equal proportions of the power to oppose destruction which he had at the commencement of each of these intervals. (05 Mar 2000) |
| chemiosmotic hypothesis | <biochemistry, cell biology> A theoretical mechanism (proposed by Mitchell) to explain energy transduction in the mitochondrion. As a general mechanism it is the coupling of one enzyme catalysed reaction to another using the transmembrane flow of an intermediate species. For example Cytochrome oxidase pumps protons across the mitochondrial inner membrane and ATP synthesis is driven by re entry of protons through the ATP synthesising protein complex. The alternative model is production of a chemical intermediate species, but no compound capable of coupling these reactions has ever been identified. (18 Nov 1997) |
| Michaelis-Menten hypothesis | <chemistry> That a complex is formed between an enzyme and its substrate (the O'Sullivan-Tompson hypothesis), which complex then decomposes to yield free enzyme and the reaction products (Brown hypothesis), the latter rate determining the overall rate of substrate-product conversion. See: Michaelis-Menten constant, Michaelis-Menten equation. (05 Mar 2000) |
| mnaemic hypothesis | The theory that stimuli or irritants leave definite traces (engrams) on the protoplasm of the animal or plant, and when these stimuli are regularly repeated they induce a habit which persists after the stimuli cease; assuming that the germ cells share with the nerve cells in the possession of engrams, acquired habits may thus be transmitted to the descendants. Synonym: mnaemic theory, mnemism, Semon-Hering theory. (05 Mar 2000) |
