The 3-Rainbow Index of a Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2015
Let G be a nontrivial connected graph with an edge-coloring c : E(G) → {1, 2, . . . , q}, q ∈ ℕ, where adjacent edges may be colored the same. A tree T in G is a rainbow tree if no two edges of T receive the same color.

Rainbow Coloring Hardness via Low Sensitivity Polymorphisms [PDF]

open access: yes, 2019
A k-uniform hypergraph is said to be r-rainbow colorable if there is an r-coloring of its vertices such that every hyperedge intersects all r color classes.

Effects of cerium dioxide nanoparticles in Oncorhynchus mykiss gills after an acute exposure: assessment of oxidative stress, genotoxicity and histological alterations

open access: yesFrontiers in Marine Science, 2015
Data about the toxicological effects of cerium dioxide nanoparticles (CeO2 NP) in fish are scarce. This work aimed to assess the CeO2 NP possible deleterious effects on the gills of Oncorhynchus mykiss.

Effects of organic plant oils and role of oxidation on nutrient utilization in juvenile rainbow trout (Oncorhynchus mykiss) [PDF]

open access: yes, 2012
The study compared the effect of four either fresh or force oxidized organic plant oils in diets for juvenile rainbow trout (Oncorhynchus mykiss) in which 47% of conventional LT fish meal protein was substituted by a mixture of 3 organic plant protein ...

Ontogenesis Evolution of Body Size Indices in Rainbow Trout (Oncorhynchus Mykiss) Reared in Different Growth Systems

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Experiments were conducted throughout 2009 and 2010. At the beginning of experiments, both in 2009 and in 2010, were formed two groups (M-control group; E-experimental group), each group far 600 rainbow trout (Oncorhynchus mykiss).

Rainbow domination and related problems on some classes of perfect graphs [PDF]

open access: yes, 2015
Let $k \in \mathbb{N}$ and let $G$ be a graph. A function $f: V(G) \rightarrow 2^{[k]}$ is a rainbow function if, for every vertex $x$ with $f(x)=\emptyset$, $f(N(x)) =[k]$.

Inflation from $f(R)$ theories in gravity's rainbow

open access: yes, 2020
In this work, we study the $f(R)$ models of inflation in the context of gravity's rainbow theory. We choose three types of $f(R)$ models: $f(R)=R+\alpha (R/M)^{n},\,f(R)=R+\alpha R^{2}+\beta R^{2}\log(R/M^{2})$ and the Einstein-Hu-Sawicki model with $n,\,

Semi-quantum approach for fast atom diffraction: solving the rainbow divergence [PDF]

open access: yes, 2014
In this work we introduce a distorted wave method, based on the Initial Value Representation (IVR) approach of the quantum evolution operator, in order to improve the semiclassical description of rainbow effects in diffraction patterns produced by ...
