An application of the Lovasz-Schrijver M(K,K) operator to the stable set problem [PDF]

open access: yes, 2009
Although the lift-and-project operators of Lovász and Schrijver have been the subject of intense study, their M(K, K) operator has received little attention. We consider an application of this operator to the stable set problem.

Collective Anti‐Mattering: Belief That One's Group Is Being Disregarded Fuels Collective Action and Authoritarian Leadership Support Among Both Advantaged and Disadvantaged Groups

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Groups are motivated not only by resources and status, but also by whether they matter to others. We introduce collective anti‐mattering, the belief that one's group does not count in the eyes of outgroups or society, and examine its emotional and political consequences.

Minimum Clique Number, Chromatic Number, and Ramsey Numbers [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
Let $Q(n,c)$ denote the minimum clique number over graphs with $n$ vertices and chromatic number $c$. We investigate the asymptotics of $Q(n,c)$ when $n/c$ is held constant. We show that when $n/c$ is an integer $\alpha$, $Q(n,c)$ has the same growth order as the inverse function of the Ramsey number $R(\alpha+1,t)$ (as a function of $t$). Furthermore,

Cultural Strength Mechanisms: Family Ethnic Socialization, Ethnic Identity, Familism Links to Rural US Latino/a Youth Prosocial Behaviors Across Time

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Cultural strength‐based models propose that family ethnic socialization promotes prosocial development in Latino/a youth through cultural values such as ethnic identity and familism. However, longitudinal research testing these serial pathways remains scarce, and prosocial behavior is understudied in rural, emerging immigrant ...

Intersection graphs associated with semigroup acts [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2019
< p>The intersection graph $\\mathbb{Int}(A)$ of an $S$-act $A$ over a semigroup $S$ is an undirected simple graph whose vertices are non-trivial subacts of $A$, and two distinct vertices are adjacent if and only if they have a non-empty intersection. In

Molecular Functions and Drug Prediction of MMP1 and TGFBR2 in Nasopharyngeal Carcinoma

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
MMP1 and TGFBR2 were validated by machine learning and external datasets as the candidate genes. Dexamethasone showed strong binding affinity to MMP1 (−7.72 kcal/mol) and TGFBR2 (−7.27 kcal/mol) in docking studies. Knockdown of MMP1 repressed the malignant phenotypes of NPC cells.

Recognition of Unipolar and Generalised Split Graphs

open access: yesAlgorithms, 2015
A graph is unipolar if it can be partitioned into a clique and a disjoint union of cliques, and a graph is a generalised split graph if it or its complement is unipolar.

The Use of an Exact Algorithm within a Tabu Search Maximum Clique Algorithm

open access: yesAlgorithms, 2020
Let G=(V,E) be an undirected graph with vertex set V and edge set E. A clique C of G is a subset of the vertices of V with every pair of vertices of C adjacent. A maximum clique is a clique with the maximum number of vertices. A tabu search algorithm for

Relative Clique Number of Planar Signed Graphs

open access: yes, 2016
A signed relative clique number of signed graph (where edges are assigned positive or negative signs) is the size of a largest subset X of vertices such that every two vertices are either adjacent or are part of a 4-cycle with an odd number of negative ...

Integrated Bioinformatics Analysis Identifies FCER1G, IL1R2, and BST1 as Diagnostic Biomarkers and Therapeutic Targets in Sepsis

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
Integrative bioinformatics and experimental validation of FCER1G, IL1R2, and BST1 as biomarkers and therapeutic targets in neonatal sepsis. ABSTRACT Background Sepsis remains difficult to diagnose since blood culture has low sensitivity and current biomarkers lack sufficient specificity.
