(1) 16, 1419 (1976)] has been thought to imply neural mechanisms with unlimited constancy, but these researchers permitted differential adaptation to the brighter and dimmer targets, which were seen haploscopically (by different eyes).
(2) Ceramics can withstand natural light, unlike painting and other art works that have to be preserved in dimmer rooms.
(3) Within a certain range of ambient illumination b-waves elicited by red (695 nm) test flashes against dimmer background lights were smaller in size than against brighter ones.
(4) Stock traders shrugged off the Fed's dimmer outlook and focused on the prospect of continued stimulus.
(5) Four operations were repetitively applied to this positive pattern so that it moved fractionally to the right, grew dimmer, moved back to the left, and grew brighter again.
(6) Responses to dimmer stimuli are determined entirely by the rods.3.
(7) A steady light which hyperpolarizes the cone membrane by the same amount as high Ca2+ has an equal effect on the amplitude of responses to bright flashes but has an entirely different action on response kinetics and on the amplitude of responses to dimmer flashes.
(8) Animals raised in 800-lx cyclic light have a significant increase in the retinal activities of the three glutathione enzymes over activities measured in animals raised in the two dimmer regimes.
(9) Subjects exposed to 1000 lux ambient light maintained significantly higher levels of alertness across the 8-hour shift than did subjects exposed to the dimmer lighting conditions.
(10) When Macmillan and her colleagues at the Institute of Education compared IQs, they found today's younger cohort of professionals was, on average, slightly dimmer than the previous, poorer generation.
(11) In Experiment 1, which involved a discriminative reaction time (RT) task, chromatic and white stimuli of the same luminance were presented on a dimmer achromatic background.
(12) Also, titration with DTNB indicates that the enzyme is a much more asymmetric dimmer in the pyridoxamine-P conformation than in the pyridoxal-P conformation.
(13) Sending love to her family, friends, and community as we all struggle to make sense of the senseless in a world that is dimmer without her light.” Others praised her activist work and her creativity, saying they could hardly believe Louisiana had lost “ such a bright light ”.
(14) Nearly everywhere in the visual field, the visibility threshold with the Dicon instrument seems equivalent to that obtained with projection perimeters, but in the most sensitive retinal areas we found the threshold stimulus (Is) to be sometimes dimmer than the "background" (Ib), which surrounds the stimulus, making a negative differential threshold (delta L = Is - Ib).
(15) The prospects appear even dimmer in light of the Commonwealth bank ending its advisory role over financing the Carmichael project.
(16) "Sea walls have the potential to save lives wherever they are built, provided the tsunami does not exceed the simulated height and runup pressures," said Dimmer.
(17) They might not work properly with dimmers yet, but they are generally smaller, brighter and softer on the eye than they used to be.
(18) During rivalry, the same steep branch of the RT-luminance function appeared, but shifted as though the probe was about 0.25 log units dimmer.
(19) Steady or noise current injection during sinusoidal light stimulation showed that (a) the decrease in the spike threshold at a dimmer mean illuminance was due to the increase in the noise variance: the noise had facilitatory effects on the spike initiation; and (b) the change in the mean potential level had little effect on the spike threshold.
(20) Lucia’s retreats allow you to take more drastic action to calm the body and mind: a full-scale withdrawal from real life, or as one book I picked up put it: “turn on your dimmer switch.” It worked for me.
Rheostat
Definition:
(n.) A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will.
Example Sentences:
(1) Defects in this control system are best conceptualized in cybernetic terms rather than in terms of the current rheostat models.
(2) Chicks, 8 days of age, were housed in a wind tunnel at temperatures from 12 to 28 C in increments of 4 C. The tunnel was equipped with a microswitch, an infrared bulb located above the switch, and a small electric fan controlled by a rheostat.
(3) We propose a "rheostat" mechanism, which suggests that bone perfusion may set limits for bone growth and remodeling.
(4) Since the orifice is in series with an approximately 10 K ohm resistance generated by a gel-filled capillary and a displacement rheostat, it floats electrically, at virtual ground.
