(1) This resembles the situation in mouse liver [E. Maser and K. J. Netter, Biochem Pharmacol 38: 3049-3054, 1989] where microsomal metyrapone reductase was inhibited by steroids and the purified enzyme was demonstrated to mediate androsterone oxidation.
(2) An equivalent electrical resonator can also be used to describe the active medium of masers.
(3) These findings lead to a new theory of static balance and the action of Corti's organ: the labyrinth functions as a traveling wave maser of which the cochlea is the slow wave structure.
(4) These results--together with previous findings, which have shown that there exist functional as well as structural relationships between microsomal mouse liver metyrapone reductase and 3 alpha-hydroxysteroid dehydrogenase from Pseudomonas testosteroni [E. Maser, U. Oppermann and K. J. Netter, Eur J Pharmacol 183:1366, 1990]--suggest that metyrapone reduction in human liver microsomes might be catalysed by a microsomal hydroxysteroid dehydrogenase.
(5) An AFL-1 helium-neon optical maser generation radiation at a wave of 632.8 mM and at an output power of 18-20 mW has been employed in the treatment of cystalgias in the past 5 years.
(6) Our experience utilizing a new design Lash-Maser silicone implant in the surgical management of impotence has been detailed.
Masker
Definition:
(n.) One who wears a mask; one who appears in disguise at a masquerade.
(v. t.) To confuse; to stupefy.
Example Sentences:
(1) Finally, three mechanisms are discussed that contribute to the absence of unmasking by masker fluctuations in hearing-impaired listeners.
(2) Detectability of a filtered probe tone (250, 500, or 1000 Hz) was measured in the presence of a narrow-band Gaussian masker centered at the signal frequency.
(3) For fixed delta T (delta T greater than 3 msec), the masking effect may actually increase for the longer, less intense noises despite the fact that, for long maskers, there is less masker energy near the signal in time.
(4) Results indicated that the MLD decreased in magnitude as the interaural phase shift of the masker increased.
(5) Forward masking, as measured behaviorally, is defined as an increase in a signal's detection threshold resulting from a preceding masker.
(6) Thus the overshoot effect was markedly reduced by aspirin because the drug partially counteracted the normally poor detectability for signals presented soon after masker onset.
(7) Masker and signal frequencies were the same as for the first experiment.
(8) The iso-forward masking contour near the threshold of the masking effect across masker frequencies approximates a fiber's frequency threshold curve (FTC).
(9) In part, the small threshold shifts can be attributed to the reduction in response variance following the masker, which is the result of the adaptation of spontaneous activity.
(10) Hence, one cannot predict masked threshold from the acoustic spectra of the maskers used here since they differ from their internal representations.
(11) The data support a spectrum-analyzer model of detection in which multiband filtering of the input smooths the masker energy in each spectral region to approximate the Gaussian case.
(12) Recent investigations of the masking-level difference (MLD) have often involved measurement of the MLD as a function of masker level.
(13) The masker with the largest amplitude fluctuations exhibited greater forward-masking ability than other stimuli; this effect was observed on the high-frequency branch and within the tip region of the tuning curve.
(14) The 20-ms signal was presented at the onset or at the temporal center of the 400-ms masker.
(15) A reaction time paradigm was used to estimate the sensitivity of four subjects to airpuffs without and during continuous vibration (masker) of low (30 Hz) or high (240 Hz) frequency.
(16) The data from all three experiments suggest that threshold signal levels in the presence of interaural differences in masker intensity depend principally on the ear with the higher signal-to-masker ratio at the output of its auditory filter, a finding consistent with the power-spectrum model of masking.
(17) Because maskers that are decorrelated yield small MLDs, the MLD is likewise small at low masker levels.
(18) For large masker separations, r greater than 0.4, no consistent effects of signal phase were observed.
(19) The IMD is dominated by the cubic component (2f1-f2) and arises from the interaction of the probe tone and the simultaneous masker.
(20) Masker duration was 20 or 400 ms; in the latter case, the signal was presented in one of three temporal positions within the masker.
