The purpose of the article is to reconstruct a fragment of K. Paustovsky’s coloristic picture of the world on the material of the story “Mescherskaya side”, which had not previously become the subject of special research carried out from the standpoint of linguistics of color, which determines the scientific novelty of this work. The research methodology is based on the descriptive and analytical method, the method of compatibility analysis, the method of contextual analysis, quantitative data processing. As the result of the research 1) the composition of color concepts, actualized by the writer in color chronotope creation, was revealed; only the color core of the story is represented by 24 color terms; 2) the dominants of the story color spectrum (black, green, gray) were determined; this color sequence is unique: it is recorded in Paustovsky’s works for the first time; 3) the color dominants denotative spheres (predominantly nature, artifacts, man) were established; 4) the functional potential of color terms was described; it includes the ontological function, the species function, the terminological function, as well as the function of temporal meaning transfer, the evaluative function, the aestheticization one; 5) the individual author’s specificity of artistic perception and reality coloristic visualization was revealed; among the significant color individual features are multicolor effect, non-stereotyped color characteristics, color associativity. The results obtained make it possible to create a comprehensive description of the story’s color conceptosphere.

We propose a practical image retrieval scheme to retrieve images efficiently. The proposed scheme transfers each image to a color sequence using straightforward 8 rules. Subsequently, using the color sequences to compare the images, namely color sequences comparison. We succeed in transferring the image retrieval problem to sequences comparison and subsequently using the color sequences comparison along with the texture feature of Edge Histogram Descriptor to compare the images of database. We succeed in transferring the image retrieval problem to quantized code comparison. Thus the computational complexity is decreased obviously. Our results illustrate it has virtues both of the content based image retrieval system and a text based image retrieval system.

Color Sequence

A sequence of symbols a1 , a2 … is called square-free if it does not contain a subsequence of consecutive terms of the form x1 , …, xm , x1 , …, xm . A century ago Thue showed that there exist arbitrarily long square-free sequences using only three symbols. Sequences can be thought of as colors on the vertices of a path. Following the paper of Alon, Grytczuk, Hałuszczak and Riordan, we examine graph colorings for which the color sequence is square-free on any path. The main result is that the vertices of any k -tree have a coloring of this kind using O ( ck ) colors if c > 6. Alon et al. conjectured that a fixed number of colors suffices for any planar graph. We support this conjecture by showing that this number is at most 12 for outerplanar graphs. On the other hand we prove that some outerplanar graphs require at least 7 colors. Using this latter we construct planar graphs, for which at least 10 colors are necessary.

Abstract Black spotting on a red or white background in pigs is determined by the EP allele at the MC1R/Extension locus. A previous comparison of partial MC1R sequences revealed that EP shares a missense mutation (D121N) with the ED2 allele for dominant black color. Sequence analysis of the entire coding region now reveals a second mutation in the form of a 2-bp insertion at codon 23 (nt67insCC). This mutation expands a tract of six C nucleotides to eight and introduces a premature stop codon at position 56. This frameshift mutation is expected to cause a recessive red color, which was in fact observed in some breeds with the EP allele present (Tamworth and Hereford). RT-PCR analyses were conducted using skin samples taken from both spotted and background areas of spotted pigs. The background red area had transcript only from the mutant nt67insCC MC1R allele, whereas the black spot also contained a transcript without the 2-bp insertion. This indicates that black spots are due to somatic reversion events that restore the frame and MC1R function. The phenotypic expression of the EP allele is highly variable and the associated coat color ranges from red, red with black spots, white with black spots, to almost completely solid black. In several breeds of pigs the phenotypic manifestation of this allele has been modified by selection for or against black spots.

The age distributions in the bar and disk of the Large Magellanic Cloud are studied using data for 262 clusters with known ages, of which 89 are located in the bar. The spatial distributions for clusters in different age groups are investigated. Epochs of active star formation are determined for the bar and disk of the LMC. The ages of the stellar populations in the bar differ from that for the galaxy as a whole: in the bar, there is a deficit of intermediate-age clusters (5 × 108–6 × 109 yr) and an excess of young clusters with ages 3 × 107–5 × 108 yr. This indicates that the star formation history in the bar differs from that in regions outside the bar at the same distances from the center of the galaxy. Data on the composition of the old stellar populations in the bar and the disk of the LMC and the spatial distribution of intermediate-age clusters in the galaxy suggest that the LMC bar formed (2–6) × 109 years ago. Deviation of colors of bars from the normal color sequence of galaxies on several two-color diagrams is found using multicolor surface photometry for eight barred galaxies. Using results of evolutionary synthesis modeling, I can model the abnormal colors of bars by an intermediate-age star (~ 109 yr) deficiency. I find that the deficiency of an intermediate-age stellar population is a general property of bars.
