Solving Graph Coloring Problems with Abstraction and Symmetry [PDF]

, 2015
This paper introduces a general methodology, based on abstraction and symmetry, that applies to solve hard graph edge-coloring problems and demonstrates its use to provide further evidence that the Ramsey number $R(4,3,3)=30$.

Spectral entropy variability of intraoperative electrocorticography predicts outcome after epilepsy surgery in people with focal cortical dysplasia

Epilepsia, EarlyView.
Abstract Objective Epilepsy surgery in people with focal cortical dysplasia (FCD) requires accurate removal of all epileptogenic tissue, and outcome is difficult to predict. We explored whether spectral entropy, a fast computable electroencephalographic (EEG) feature, could estimate epileptic activity in intraoperative electrocorticography (ioECoG) and

On the Ramsey-Tur\'an number with small $s$-independence number [PDF]

, 2015
Let $s$ be an integer, $f=f(n)$ a function, and $H$ a graph. Define the Ramsey-Tur\'an number $RT_s(n,H, f)$ as the maximum number of edges in an $H$-free graph $G$ of order $n$ with $\alpha_s(G) < f$, where $\alpha_s(G)$ is the maximum number of ...

Enhancing Volatility Prediction: A Wavelet‐Based Hierarchical Forecast Reconciliation Approach

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting realized volatility (RV) has been widely studied, with numerous techniques developed to enhance predictive accuracy. Among these techniques, the use of RV decompositions based on intraday asset returns has been applied. However, the use of a frequency‐based decomposition, which provides unique insights into the dynamics of RV ...

Medicare Part D and Hospital Admissions due to Antimicrobial Resistance

Health Economics, EarlyView.
ABSTRACT Antimicrobial resistance (AMR) has been increasing rapidly in the United States despite government efforts to contain its spread. Both under‐utilization and overuse of prescribed antimicrobials contribute to rising resistance. The introduction of Medicare Part D in 2006 expanded prescription drug coverage for the elderly, including coverage ...

The k-Ramsey number of two five cycles

AKCE International Journal of Graphs and Combinatorics
Given any two graphs F and H, the Ramsey number R(F, H) is defined as the smallest positive integer n such that every red-blue coloring of the edges of the complete graph Kn of order n, there will be a subgraph of Kn isomorphic to F whose edges are all ...

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

Human 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.

Hedgehogs are not colour blind [PDF]

, 2015
We exhibit a family of $3$-uniform hypergraphs with the property that their $2$-colour Ramsey numbers grow polynomially in the number of vertices, while their $4$-colour Ramsey numbers grow exponentially.

Material ESG Performance and Bid Premium in Merger and Acquisition Deals

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the firm‐level and country‐level environmental, social, and governance (ESG) performance on bid premiums in cross‐border mergers and acquisitions (M&A) transactions. We document considerable variations in bid premiums. Higher carbon emissions are associated with higher bid premiums, suggesting that acquirers may perceive ...

On Monochromatic Subgraphs of Edge-Colored Complete Graphs

Discussiones Mathematicae Graph Theory, 2014
In a red-blue coloring of a nonempty graph, every edge is colored red or blue. If the resulting edge-colored graph contains a nonempty subgraph G without isolated vertices every edge of which is colored the same, then G is said to be monochromatic.
