When the adaptation level is not high enough, the maximum adaptation stimulus is not equal with the plot of illuminant. This property is accepted in this paper. Using this property, we propose a chromatic adaptation model for the level of adapting luminance and chromaticity in various surrounding illuminants. In this model, we calculate the maximum adapting responses using adapting degree for v...

In the near future... Imagine a businessman preparing for a trip to some western metropolis to meet a customer. As usually, he organizes his trip via the World Wide Web checking how to get to his destination, finding reasonable accommodation and investigating things to do in his free time. To keep himself occupied during his journey, he might listen to his music collection while surfing the mob...

This paper investigates the processes used by an evolved, embodied simulated agent to adapt to large disruptive changes in its sensor morphology, whilst maintaining performance in a phototaxis task. By avoiding the imposition of separate mechanisms for the fast sensorimotor dynamics and the relatively slow adaptive processes, we are able to comment on the forms of adaptivity which emerge within...

Adapting to change has always been one of the basic requirements of life. In the long run, the price of not adapting is failure to survive. Change has, of course, been getting faster in every way since the industrial revolution began. But it now presents a psychological threat to almost everyone. This threat comes from the clash between the increasing need to adapt and those strong forces, both...

We report a new type of orientation-contingent color aftereffect in which the color aftereffect is opposite to the classical McCollough effect, i.e., the perceived color of the aftereffect is the same as the inducer's color. Interleaved exposure to red, horizontal and achromatic (gray), horizontal gratings led to a long-lasting aftereffect in which achromatic horizontal gratings appeared reddis...

We describe our experience in adapting an existing high-quality, interlingual, unidirectional machine translation system to a new domain and bidirectional translation for a new language pair (English and Italian). We focus on the interlingua design changes which were necessary to achieve high quality output in view of the language mismatches between English and Italian. The representation we pr...

The time course of recovery of spatial resolution following adaptation to a uniform field was measured for test probes presented at lower illuminance than the adapting field. Six observers were tested in a Maxwellian-view system using 20 degrees adapting fields of 1.6-2.6 log photopic trolands. Test stimuli were 7 degrees, 250 ms Gabor patches (1 and 6 cpd) of mean retinal illuminance 2-3 log u...

Recordings from the rat optic tract fibers were used to assess changes in sensitivity under various conditions of adaptation. An adapting background which excites only a small fraction of the rods can yet cause a several-fold change in sensitivity. A small adapting spot much more effectively decreases the cell’s sensitivity to a superimposed test than to test spots in positions far from the ada...

In this paper, we investigated the effect of chromaticity and luminance of surround to decide subject neutral white, and conducted a mathematical model of adapting degree for environment. Factors for adapting degree consist of two parts, adapting degree of ambient chromaticity and color saturation. These can be applied to color appearance models (CAM), actually improve the performance of color ...

uring meiosis I, some mechanism must allow homologous chromosomes to separate while keeping sister chromatids paired until meiosis II. How does a cell make this distinction? On page 219, Rogers et al. propose that in C. elegans the aurora-B kinase AIR-2 is largely responsible for ensuring that cohesion between chromosomes breaks down at the proper place and time. The authors also identified add...
