Paired photoreceptors function as an oceanic depth gauge

Divergence by depth in an oceanic fish

Despite the striking physical and environmental gradients associated with depth variation in the oceans, relatively little is known about their impact on population diversification, adaptation and speciation. Changes in light associated with increasing depth are likely to alter the visual environment of organisms, and adaptive changes in visual systems may be expected. The pelagic beaked redfis...

Depth Perception as a Function of Age

Binocular depth perception was investigated in 164 healthy Ss of the Normative Aging Study, in connection with a model of ocular aging which explains change in the dioptric media in the forties on the basis of mechanical change and later change in the retina on the basis of metabolic change. A modified Verhoeff stereopter was used. The results showed a marked diminution to make stereoptic judgm...

Don’t Be Depth Charged by the Depth Gauge

Dear Sir/Madam, The depth gauge is an essential device used while performing open plate or interosseous screw fixation of hand fractures allowing for anatomically accurate and safe insertion of screws. An efficient pass through the drilled path provides the best chance at accurate estimation of correct screw length. The most common error is inaccurate measurement of the length of the drilled ho...

Gauge federation as an alternative to unification

Depth Perception as a Function of Lighting, Time and Spatiality

Perceptual qualities of luminous environment change based on spatiality, time, and observer. This paper focuses on the complex interrelationships between architectural configurations, luminance distribution patterns, and the perception of spatial depth. A computational framework that draws from the recent developments in computer graphics (physically based renderings and perceptually based tone...
