A thick cloud of Neptune Trojans and their colors.
The dynamical and physical properties of asteroids offer one of the few constraints on the formation, evolution, and migration of the giant planets. Trojan asteroids share a planet's semimajor axis but lead or follow it by about 60 degrees near the two triangular Lagrangian points of gravitational equilibrium. Here we report the discovery of a high-inclination Neptune Trojan, 2005 TN(53). This ...
متن کاملLuminance contours can gate afterimage colors and "real" colors.
It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test contours presented after the colored image. The color of the afterimage depends on two adapting colors, those both inside and outside the test. He...
متن کاملWatermarking Spot Colors Osama
Watermarking of printed materials has usually focused on process inks of cyan, magenta, yellow and black (CMYK). In packaging, almost three out of four printed materials include spot colors. Spot colors are special premixed inks, which can be produced in a vibrant range of colors, often outside the CMYK color gamut. In embedding a watermark into printed material, a common approach is to modify ...

Bruce Thacker never took an art class. He never even took a computer class. His degree is in geology, and he fi rst bought a computer in 1990 to track stock investments. Somewhere in the convoluted melange of his linear history, he owned a contemporary art gallery, invested in stocks and real estate, owned a custom photo lab, and was a professional photographer. “Other things that I’ve never ha...
متن کاملTiles and Colors
Tiling models are classical statistical models in which different geometric shapes, the tiles, are packed together such that they cover space completely. In this paper we discuss a class of two-dimensional tiling models in which the tiles are rectangles and isosceles triangles. Some of these models have been solved recently by means of Bethe Ansatz. We discuss the question why only these models...
