| A-mode | In diagnostic ultrasound, a one-dimensional presentation of a reflected sound wave in which echo amplitude (A) is displayed along the vertical axis and time of rebound (depth) along the horizontal axis; the echo information is presented from interfaces along a single line in the direction of the sound beam.

| ballooning mode | <radiobiology> A mode which is localised in regions of unfavorable magnetic field curvature (bad curvature) and which becomes unstable when the force due to pressure gradients (grad p) is greater than the mean magnetic pressure force (grad B^2)/(8pi) in cgs units. (09 Oct 1997) |
| Bernstein mode | <radiobiology> Type of mode which propagates perpendicular to the equilibrium magnetic field in a hot plasma. The waves have their electric field nearly parallel to the wave propagation vector (nearly longitudinal). The modes propagate in frequency ranges lying between integer harmonics of the electron cyclotron frequency. Named after Ira Bernstein. (09 Oct 1997) |
| B-mode | A two-dimensional diagnostic ultrasound presentation of echo-producing interfaces in a single plane; the intensity of the echo is represented by modulation of the brightness (B) of the spot, and the position of the echo is determined from the position of the transducer and the transit time of the acoustical pulse. (05 Mar 2000) |
| B-mode echocardiography | two-dimensional echocardiography |
| M-mode | A diagnostic ultrasound presentation of the temporal changes in echoes in which the depth of echo-producing interfaces is displayed along one axis with time (T) along the second axis; motion (M) of the interfaces toward and away from the transducer is displayed. Synonym: TM-mode. (05 Mar 2000) |
| mode | 1. Manner of doing or being; method; form; fashion; custom; way; style; as, the mode of speaking; the mode of dressing. "The duty of itself being resolved on, the mode of doing it may easily be found." (Jer. Taylor) "A table richly spread in regal mode." (Milton) 2. Prevailing popular custom; fashion, especially in the phrase the mode. "The easy, apathetic graces of a man of the mode." (Macaulay) 3. Variety; gradation; degree. 4. <psychology> Any combination of qualities or relations, considered apart from the substance to which they belong, and treated as entities; more generally, condition, or state of being; manner or form of arrangement or manifestation; form, as opposed to matter. "Modes I call such complex ideas, which, however compounded, contain not in them the supposition of subsisting by themselves, but are considered as dependencies on, or affections of, substances." (Locke) 5. <logic> The form in which the proposition connects the predicate and subject, whether by simple, contingent, or necessary assertion; the form of the syllogism, as determined by the quantity and quality of the constituent proposition; mood. 6. Same as Mood. 7. The scale as affected by the various positions in it of the minor intervals; as, the Dorian mode, the Ionic mode, etc, of ancient Greek music. In modern music, only the major and the minor mode, of whatever key, are recognised. 8. A kind of silk. See Alamode. Synonym: Method, manner. See Method. Origin: L. Modus a measure, due or proper measure, bound, manner, form; akin to E. Mete: cf. F. Mode. See Mete, and cf. Commodious, Mood in grammar, Modus. Source: Websters Dictionary (01 Mar 1998) |
| tearing mode | <radiobiology> A resistive magnetohydrodynamic instability which is spatially localised near a rational surface and which grows at a rate slower than the magnetohydrodynamic Alfven rate, but faster than the resistive skin diffusion rate. The instability tears magnetic field lines and reconnects them into a new state of lower magnetic energy. Synonym: tearing instability (09 Oct 1997) |
| edge-localised mode | Found often in H-mode plasmas, this is a temporary relaxation of the very high edge gradients found in H-modes. It may be a relaxation back to the L-mode. (09 Oct 1997) |
| TM-mode | A diagnostic ultrasound presentation of the temporal changes in echoes in which the depth of echo-producing interfaces is displayed along one axis with time (T) along the second axis; motion (M) of the interfaces toward and away from the transducer is displayed. Synonym: TM-mode. (05 Mar 2000) |
| assisted cephalic delivery | Extraction of a foetus that presents by the head. (05 Mar 2000) |
| assisted circulation | Pumping that aids the natural activity of the heart. (12 Dec 1998) |
| assisted mechanical ventilation | <anaesthetics> The use of a mechanical device to fill the lungs with oxygenated air then allow time for passive exhalation. (27 Sep 1997) |
| assisted reproductive technology | Originally, a range of techniques for manipulating eggs and sperm in order to overcome infertility. Encompasses drug treatments to stimulate ovulation; surgical methods for removing eggs (e.g., laparoscopy and ultrasound-guided transvaginal aspiration) and for reimplanting embryos (e.g., zygot intrafallopian transfer (or ZIFT); in vitro and in vivo fertilization (e.g., artificial insemination and gamete intrafallopian transfer (or GIFT); ex utero and in utero foetal surgery; as well as laboratory regimes for freezing and screening sperm and embryos, and micromanipulating and cloning embryos. The field's first major success came in 1978 with the birth of "test-tube baby" Louise Brown, engineered by Steptoe, Edwards, et al., of England. As the technologies spread, they increasingly are being employed for purposes beyond infertility, i.e., to reduce the risk of, or avoid passing on, hereditary disease and to select for infant sex. Further uses that would aim at improving the "quality" of offspring have been widely discussed and raise profound legal and ethical questions. See: eugenics. (05 Mar 2000) |
| assisted respiration | Application of mechanically or manually generated positive pressure to gas(es) in or about the airway during inhalation as a means of augmenting movement of gases into the lungs. Synonym: assisted respiration. (05 Mar 2000) |
