Combination of Colour Favoured and Colour

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

Petal Width, Cm Petal Width, Cm

There are several reasons why this book might be of interest to a TEX user. First, LTEX has a prominent place in the book. Second, the book describes a very interesting offshoot of literate programming, a topic traditionally popular in the TEX community. Third, since a number of TEX users work with data analysis and statistics, R could be a useful tool for them. Since some TUGboat readers are l...

Violet/blue chrysanthemums--metabolic engineering of the anthocyanin biosynthetic pathway results in novel petal colors.

Chrysanthemums (Chrysanthemum×morifolium Ramat.) are an important cut-flower and potted plant crop in the horticultural industry world wide. Chrysanthemums express the flavonoid 3'-hydroxylase (F3'H) gene and thus accumulate anthocyanins derived from cyanidin in their inflorescences which appear pink/red. Delphinidin-based anthocyanins are lacking due to the deficiency of a flavonoid 3', 5'-hyd...

Colour vision impairment in migraine--out of the blue?

EDITORIAL Colour vision impairment in migraine – out of the blue? For many decades, clinicians and scientists have been particularly interested in those aspects of migraine that relate to the various components of the visual system. This is less surprising than it may seem, since many patients report prominent and at times incapacitating visual features. Among the most enigmatic of these one ma...

Action of Red-sensitive Colour Mechanism on Blue-sensitive Colour Mechanism in Visual Masking

In the visual masking effect, metacontrast, the perceived brightness, of a flash of light is reduced by the presentation of a second flash in an adjacent region of the visual field . A metacontrast masking interaction between different colour mechanisms is examined in the present study . The spectral compositions and intensities of the stimuli are chosen so that the first (test) flash preferent...
