In the previous paper, it was shown that the graph U. ÷ 1 obtained from the wheel W n ÷ 1 by deleting a spoke is uniquely determined by its chromatic polynomial if n >i 3 is odd. In this paper, we show that the result is also true for even n >~ 4 except when n = 6 in which case, the graph W given in the paper is the only graph having the same chromatic polynomial as that of U 7. The relevant to...

In visual search experiments we examined whether targets that are distinguished from distracting items solely by a contrary change in color can be sought spatially in parallel. Targets under time-varying illumination pop out if they present a contrary luminance signal; targets under space-varying illumination can be detected in parallel when they are isoluminant. The results suggest that neuron...

Abstract Carillons are a diverse and global form of musical civic heritage: instruments comprised series 23 or more bells, typically hung in tower-like structure, tuned chromatically played from touch-sensitive manual pedal console using an elaborate mechanical action. Carillon bells have distinct overtones which should be accurately to one another with other they sound alongside. Although thes...

The question of whether a species matches the colour of its natural background in the perspective of the correct receiver is complex to address for several reasons; however, the answer to this question may provide invaluable support for functional interpretations of colour. In most cases, little is known about the identity and visual sensory abilities of the correct receiver and the precise loc...

Color discrimination is influenced by chromatic distributions such as they appear on differently illuminated 3D surfaces (T. Hansen, M. Giesel, & K. R. Gegenfurtner, 2008). Here, we measured discrimination thresholds for chromatically variegated stimuli and modeled the data employing a model with multiple chromatic mechanisms. Each mechanism has a differently tuned half-wave-rectified cosine-sh...

The hitherto unknown male of the widespread and tramp species, Calliscelioelegans (Hymenoptera, Platygastridae) is hereby reported for the first time, from India. The two sexes are chromatically quite similar. The male has the same conspicuous banding pattern in the forewing as that of the female. The status of Caloteleatanugatra Narendran (Hymenoptera, Platygastridae) from India is reviewed an...

Color visualization of the DNA diverse living beings can help in exploration issue chromatic differentiation functional mappings nucleotide composition molecules. By “chromatic differentiation”, we mean coloring these mappings. Algorithms for genetic representations improve perception complex information using color. Methodologically, to build DNA, employed system Walsh functions and Chaos Game...
