Deciduous tree species throughout the boreal forest of North America have lighter-coloured bark than do species restricted to more southern forests. We tested the hypothesis that light-coloured bark minimizes the thawing and freezing of cambium tissue during winter that could contribute to sunscald injury. During mid-winter, maximum midday cambium temperatures of south-exposed bark of white bir...

In this paper, we introduce two novel techniques for digital color halftoning with green-noise--stochastic dither patterns generated by homogeneously distributing minority pixel clusters. The first technique employs error diffusion with output-dependent feedback where, unlike monochrome image halftoning, an interference term is added such that the overlapping of pixels of different colors can b...

For centuries painters have predominantly painted portraits with the model’s left-cheek facing the viewer. This has been even more prevalent with females (:68%) than males (:56%). Numerous portraits painted by Rembrandt typify this unexplained phenomenon. In a preliminary experiment, subjects judged 24 emotional and social character traits in 20 portraits by Rembrandt. A factor analysis reveale...

Colorization is a computerized process of adding color to a black and white print, movie and TV program. The authors have proposed automatic colorization algorithms by giving a partial color to a monochrome image. This paper focuses on the colorization process which can produce a color image from a monochrome image with a small number of color pixels, and proposes a novel color image coding alg...

Aim: Our aim was to gain an idea about testicular injury by comparing the reduced volume, which is one of indirect indicators damage in undescended testes, and evaluating microvascular blood flow superb imaging, also determine whether imaging modes could detect more detail decreased volume testes. Material methods: We compared testes via conventional Doppler color monochrome techniques with con...

This paper considers the results of an examination painted pottery from prehistoric sites Prmor’ye region (Southern Russian Far East) in northwestern part Sea Japan basin. Red-painted and black-painted ceramic wares occur here only remains Yankovskaya archaeological culture dated to 1st mil. BCE. Red painting appears as a colored surface coating, black is represented by very simple drawn patter...

In this study, a culture-independent Illumina MiSeq sequencing strategy was applied to investigate the microbial communities colonizing the ancient painted sculptures of the Maijishan Grottoes, a famous World Cultural Heritage site listed by UNESCO in China. Four mixed samples were collected from Cave 4-4 of the Maijishan Grottoes, the so-called Upper Seven Buddha Pavilion, which was built duri...
