Bipartite rainbow Ramsey numbers

open access: yesDiscrete Mathematics, 2004
This article introduces, proves the existence of, and computes some values of a new Ramsey number. Given a graph \(G\), with a subgraph \(H\), call an edge-coloring of \(G\) {rainbow} on \(H\) if the coloring assigns every edge of \(H\) its own color.

Reduction of Ribonucleotide Reductase Subunit RRM2 Potentially Impairs Gut Function of Woody Breast Broilers

open access: yesAnimal Research and One Health, EarlyView.
Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...

RAMSEY NUMBERS FOR TREES [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2012
AbstractForn≥5, letT′ndenote the unique tree onnvertices with Δ(T′n)=n−2, and letT*n=(V,E) be the tree onnvertices withV={v0,v1,…,vn−1} andE={v0v1,…,v0vn−3,vn−3vn−2,vn−2vn−1}. In this paper, we evaluate the Ramsey numbersr(Gm,T′n) andr(Gm,T*n) , whereGmis a connected graph of orderm.

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

Anti-Ramsey numbers for disjoint copies of graphs [PDF]

open access: yesOpuscula Mathematica, 2017
A subgraph of an edge-colored graph is called rainbow if all of its edges have different colors. For a graph \(G\) and a positive integer \(n\), the anti-Ramsey number \(ar(n,G)\) is the maximum number of colors in an edge-coloring of \(K_n\) with no ...

Evaluating the Impact of a Dedicated Dissection Course on 3‐D Anatomical Understanding in Senior Medical Students

open access: yesClinical Anatomy, EarlyView.
ABSTRACT International changes in the focus of medical school education have led to a decrease in the time allocated to anatomy education, with human specimen dissection particularly affected. This study evaluates whether a dissection‐based course facilitates the retention of three‐dimensional (3‐D) anatomical relationships in senior medical students ...

Star-Critical Weakened Ramsey Numbers

open access: yesTheory and Applications of Graphs
The weakened Ramsey number $r^{s,t}(G)$ is defined to be the least $p\in \mathbb{N}$ such that every $t$-coloring of the edges of the complete graph $K_p$ contains a subgraph isomorphic to $G$ that is spanned by edges that use at most $s$ colors ($1\le s\
