ions, as has repeatedly been emphasised in the literature. Stumpf (1917, p. 8), for instance, insisted that a specification of colour attributes is based on the "ability and the conditions for an isolating abstraction"; and Burnham, Hanes & Bartleson (1963, p. 5), in a report on behalf of the Inter-Society Color Council, regarded these "visually abstractable dimensions" as representing "an abst...

The recent discovery of CDF anomaly suggest the existence of a new long-lived particle which means a dramatic deviation from standard model. This article summarizes the quantum model of CDF anomaly. The anomaly is interpreted in terms of production of τ -pions which can be regarded as pion like bound states of color octet excitations of τ -leptons and corresponding neutrinos. Colored leptons ar...

Mythili Menon and Roumyana Pancheva; University of Southern California We provide evidence for the ambiguity in color terms (e.g., green) between a gradable and nongradable reading, as proposed in [5]. The evidence comes from color terms in Malayalam. Expressions for color exhibit different morphosyntactic behavior in attributive and predicative positions, and in comparatives, as opposed to oth...

A growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables. The basic assumption of the model is that the timing of a consumer's initial purchase is related to the number of previous buyers. A behavioral rationale for the model is offered in terms of innovative and imitative behavior. The model yields good pred...

Recently, it has been demonstrated that people associate each of the basic tastes (e.g., sweet, sour, bitter, and salty) with specific colors (e.g., red, green, black, and white). In the present study, we investigated whether pairs of colors (both associated with a particular taste or taste word) would give rise to stronger associations relative to pairs of colors that were associated with diff...

Anthocyanin pigments have become a model trait for evolutionary ecology as they often provide adaptive benefits for plants. Anthocyanins have been traditionally quantified biochemically or more recently using spectral reflectance. However, both methods require destructive sampling and can be labor intensive and challenging with small samples. Recent advances in digital photography and image pro...

  Background: Equine chorionic gonadotropin (eCG) is commonly used in association with a progestagen treatment to synchronize estrus of goats and ewes during breeding and non-breeding seasons. Classical purification of the eCG from serum includes pH fractionation with metaphosphoric acid two ethanol precipitation steps as...

Color is one of the most prominent features of an image and used in many skin and face detection applications. Color space transformation is widely used by researchers to improve face and skin detection performance. Despite the substantial research efforts in this area, choosing a proper color space in terms of skin and face classification performance which can address issues like illumination ...
