Psychologically pure colors are colors that exhibit a homogeneous appearance on some dimension of perceived color. Purity of appearance is closely tied up with theoretical understandings of the three canonical color attributes of hue, saturation, and lightness. According to the dominant Hering opponent color framework, the hues red, green, blue, and yellow are distinctive and fundamental to all...

We examine the spectra and infrared colors of the cool methane-dominated atmospheres at Teff ≤ 1400 K expected for young gas giant planets. We couple these spectral calculations to an updated version of the Marley et al. (2007) giant planet thermal evolution models that include formation by core accretion-gas capture. These relatively cool “young Jupiters” can be 1-6 magnitudes fainter than pre...

We present 70 m properties of submillimeter galaxies (SMGs) in the Great Observatories Origins Deep Survey (GOODS) North field. Out of 30 submillimeter galaxies (S850 > 2 mJy) in the central GOODS-N region, we find two with secure 70 m detections. These are the first 70 m detections of SMGs. One of the matched SMGs is at z 0:5, and has S70 /S850 and S70 /S24 ratios consistent with a cool galaxy...

the significance of mysticism can be traced in relying on illumination rather than logic and reasoning to discover the truth. theoretically speaking, mysticism means having belief in understanding the truth and practically speaking it means leaving superficial customs and resorting to suffering. mysticism among muslims is exclusive to mystics who have changed names over time. sufi is someone wh...

The star LHS 3250 is found to be a white dwarf at a distance of 30 pc. Its absolute magnitudes (MV = 15.72; Mbol = 16.2) put it among the least-luminous white dwarfs known. Its optical spectrum shows no features, indicating it has a DC classification, and it shows no detectable polarization, indicating it does not have a very strong magnetic field. However, its broadband colors show it to have ...

The term ‘cool’ is widely used expression in popular culture. This word is prefixed liberally with anything including people, behavior, place and brands. Notwithstanding ambiguity about what it stands there is complete clarity that it certainly adds value. ‘Cool’ in this perspective is precious resource which can be used in brand building. The authors’ exploration into its genesis and meaning r...

Grayscale images are fundamental to many image processing applications like data compression, feature extraction, printing and tone mapping. However, some information is lost when converting from color grayscale. In this paper, we propose a light-weight high-speed decolorization method based on human perception of temperatures. Chromatic aberration results differential refraction light dependin...

The present generation of rotating refrigerators, which are used for the study of quantized vorticity in helium superfluids, are often capable of cooling to mK temperatures and rotate up to ’ 1 rev/s. To achieve single-vortex resolution at all rotation velocities, smooth and stable rotation is required. This calls for low and stable rotational friction, sufficient axial alignment and lateral ba...
