Ramsey numbers for matchings

open access: yesDiscrete Mathematics, 1980
AbstractWe consider the Ramsey number r(sK2, G) where sK2(s⩾1) denotes a set of s disjoint edges and G is an arbitrary finite simple graph with no isolated vertices. We obtain upper and lower bounds in the general case. Exact results are obtained for certain classes of graphs.

Moderate Amylose Increases From SSIIa Mutations Modify Pasta Texture in Durum Wheat

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Durum wheat (Triticum turgidum L. subsp. durum) pasta quality depends on grain yellowness, gluten strength, and protein content, and can be modified by altering starch composition. High‐amylose null mutants improve nutritional traits but often reduce seed size, yield, and processing quality.

Characterization of NAT2 Using Long‐Read Sequencing: Allele, Diplotype, and Phenotype Call Accuracy Compared to Other Testing Strategies

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The NAT2 pharmacogene is essential in drug metabolism, particularly for aromatic amines and hydrazines. Genetic variations in NAT2 categorize individuals as rapid, intermediate, or poor metabolizers based on their acetylation capacity to inform dosing guidelines.

The bipartite Ramsey numbers $BR(C_8, C_{2n})$ [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
For the given bipartite graphs $G_1,G_2,\ldots,G_t$, the multicolor bipartite Ramsey number $BR(G_1,G_2,\ldots,G_t)$ is the smallest positive integer $b$ such that any $t$-edge-coloring of $K_{b,b}$ contains a monochromatic subgraph isomorphic to $G_i ...

On Ramsey numbers of fans

open access: yesDiscrete Applied Mathematics, 2009
The graph \(F_n = K_1 + nK_2\) is the Fan graph, and consists of \(n\) triangles sharing a single vertex. It was shown in [\textit{Y. Li} and \textit{C.C. Rousseau}, J. Graph Theory 23, No.\,4, 413--420 (1996; Zbl 0954.05031)] that the Ramsey number \(r(F_1, F_n) = 4n + 1\) for \(n \geq 2\), and this result is extended by showing that \(r(F_2, F_n ...

Negative learning emotions and learning goal orientation in teams: HRD implications

open access: yesHuman Resource Development Quarterly, Volume 36, Issue 1, Page 49-67, Spring 2025.
Abstract Utilizing insights from team regulation theory and social cognitive theory, this research conducted empirical testing through a field survey involving engineering teams. This research is significant as it inspires teams to effectively harness their learning capacity, thereby enhancing collective motivation for future success.

Another View of Bipartite Ramsey Numbers

open access: yesDiscussiones Mathematicae Graph Theory, 2018
For bipartite graphs F and H and a positive integer s, the s-bipartite Ramsey number BRs(F,H) of F and H is the smallest integer t with t ≥ s such that every red-blue coloring of Ks,t results in a red F or a blue H.

Bipartite Ramsey numbers involving stars, stripes and trees

open access: yesElectronic Journal of Graph Theory and Applications, 2013
The Ramsey number R(m, n) is the smallest integer p such that any blue-red colouring of the edges of the complete graph Kp forces the appearance of a blue Km or a red Kn.
