We establish a coloring theorem for successors of a singular cardinals, and use it prove that for any such cardinal μ, we have μ+ 9 [μ+]2 μ+ if and only if μ+ 9 [μ]θ for arbitrarily large θ < μ.

DNATagger is a web-based tool for coloring and editing DNA, RNA and protein sequences and alignments. It is dedicated to the visualization of protein coding sequences and also protein sequence alignments to facilitate the comprehension of evolutionary processes in sequence analysis. The distinctive feature of DNATagger is the use of codons as informative units for coloring DNA and RNA sequences...

Reproducing skin colors pleasingly is essential for photographic color reproduction. Moving skin colors toward their preferred skin color center improves the skin color preference. Two main factors to successfully enhance skin colors are: a method to detect skin colors effectively and a method to morph skin colors toward a preferred skin color region properly. This paper starts with introducing...

Karger, Motwani and Sudan presented a graph coloring algorithm based on semidefinite programming, which colors any k-colorable graph with maximum degree ∆ using Õ(∆1−2/k) colors. This algorithm leads to an algorithm for k-colorable graph using Õ(n1−3/(k+1)) colors. This improved Wigderson’s algorithm, which uses O(n1−1/(k−1)) colors, containing as a subroutine an algorithm using (∆ + 1) colors ...

Introduction An important part of color reproduction is the rendering of colors onto display devices [1], where the colors may be spot colors (e.g., tints) or the colors of a digitized photograph. Display devices, such as monitors and printers, are capable of showing only a subset of all perceivable colors; this subset is called the device color gamut. Colors subjected to a reproduction system ...

It is a classical result from graph theory that the edges of an l{regular bipartite graph can be colored using exactly l colors so that edges that share an endpoint are assigned diierent colors. In this paper we study two constrained versions of the bipartite edge coloring problem. { Some of the edges adjacent to a pair of opposite vertices of an l-regular bipartite graph are already colored wi...

background: adverse effect of sun rays mainly uv ray on the human eye documented and protection of eyes is necessary using different methods such as, sun glasses. sunglasses are designed in different colors. the aim of this study was evaluation of the effect of different colors of sunglasses on the visual acuity, contrast sensitivity, stereopsis and color vision. methods: 81 normal subjects wer...

Results: need of the search of new ways of the increase of efficiency of the competitive activity of young handball players is proved theoretically. Psychological characteristics of handball players of 13–14 years old with a different force of the nervous system are provided. Practical recommendations about the organization of pregame warm-up of handball players of 13–14 years old taking into a...

The field of condensed matter physics had its genesis this century and it has had a remarkable evolution. A closer look at its growth reveals a hidden aim in the collective consciousness of the field a part of the development this century is a kind of warm up exercise to understand the nature of living condensed matter, namely the field of biology, by a growing new breed of scientists in the co...
