Worm Colorings

open access: yesDiscussiones Mathematicae Graph Theory, 2015
Given a coloring of the vertices, we say subgraph H is monochromatic if every vertex of H is assigned the same color, and rainbow if no pair of vertices of H are assigned the same color. Given a graph G and a graph F, we define an F-WORM coloring of G as

Color on color, what color is it?

open access: yesMammalogy Notes, 2023
Leucism is expressed as the almost total decoloration of certain or whole parts of the body, but preserving the typical color of eyes, nails, and skin. We show the first known case of leucism in a three-striped palm squirrel in Telangana, India. On 12th December 2022, we observed a white-coloured juvenile three-striped palm squirrel along with its ...

Colorful Image Colorization [PDF]

open access: yes, 2016
Given a grayscale photograph as input, this paper attacks the problem of hallucinating a plausible color version of the photograph. This problem is clearly underconstrained, so previous approaches have either relied on significant user interaction or resulted in desaturated colorizations.

Local edge coloring of graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let be a graph. A local edge coloring of G is a proper edge coloring such that for each subset S of E(G) with there exist edges such that where ns is the number of copies of P3 in the edge induced subgraph The maximum color assigned by a local edge ...

La photopeinture en quête de définition (1860-1900)

open access: yesPhotographica, 2023
While photography was initially condemned to monochromy, the 19th century rapidly asserted itself as a century on a quest for color. Overpainting, as one of the solutions to this limitation of the medium, developed and oscillated between retouching and ...

Influence of the natural dyes bixin and curcumin in the shelf life of eggs from laying hens in the second production cycle - doi: 10.4025/actascianimsci.v34i2.12096

open access: yesActa Scientiarum: Animal Sciences, 2011
This study was developed to evaluate the effect of adding natural pigments on the storage of eggs from laying hens in the second production cycle submitted to diets based on corn and low-tannin sorghum.

Effects of Color and Glitter on the Removable Space Maintainer [PDF]

open access: yesJournal of Dental Materials and Techniques, 2020
Introduction: It may be necessary to make some modifications to the removable space maintainers for the persuasion of children to use this device. However, modification of the polymethyl methacrylate (PMMA) may affect its mechanical properties as well ...

Between coloring and list-coloring: μ-coloring

open access: yesElectronic Notes in Discrete Mathematics, 2005
A new variation of the coloring problem, μ-coloring, is defined in this paper. A coloring of a graph G = (V,E) is a function f : V → N such that f(v) 6= f(w) if v is adjacent to w. Given a graph G = (V,E) and a function μ : V → N, G is μ-colorable if it admits a coloring f with f(v) ≤ μ(v) for each v ∈ V .

Color Portraits [PDF]

open access: yesProceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015
Although ubiquitous, color pickers have remained largely unchanged for 25 years. Based on contextual interviews with artists and designers, we created the Color Portraits design space to characterize five key color manipulation activities: sampling and tweaking individual colors, manipulating color relationships, combining colors with other elements ...
