Anti-Ramsey Number of Hanoi Graphs

Discussiones Mathematicae Graph Theory, 2019
Let ar(G,H) be the largest number of colors such that there exists an edge coloring of G with ar(G,H) colors such that each subgraph isomorphic to H has at least two edges in the same color. We call ar(G,H) the anti- Ramsey number for a pair of graphs (G,

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

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 ...

Singular Ramsey and Turán numbers

Theory and Applications of Graphs, 2019
We say that a subgraph F of a graph G is singular if the degrees d_G(v) are all equal or all distinct for the vertices v of F. The singular Ramsey number Rs(F) is the smallest positive integer n such that, for every m at least n, in every edge 2-coloring

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.

On the Restricted Size Ramsey Number Involving a Path P3

Discussiones Mathematicae Graph Theory, 2019
For any pair of graphs G and H, both the size Ramsey number ̂r(G,H) and the restricted size Ramsey number r*(G,H) are bounded above by the size of the complete graph with order equals to the Ramsey number r(G,H), and bounded below by e(G) + e(H) − 1 ...

Gallai-Ramsey number of an 8-cycle

AKCE International Journal of Graphs and Combinatorics, 2020
Given graphs G and H and a positive integer k, the Gallai-Ramsey number is the minimum integer N such that for any integer every k-edge-coloring of Kn contains either a rainbow copy of G or a monochromatic copy of H.

Experimental Determination of Ramsey Numbers [PDF]

Physical Review Letters, 2013
Ramsey theory is a highly active research area in mathematics that studies the emergence of order in large disordered structures. Ramsey numbers mark the threshold at which order first appears and are extremely difficult to calculate due to their explosive rate of growth.

Household Consumption Intentions by Income Group During Monetary Policy Easing and Tightening

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate how the monetary policy interest rate affects Brazilian households' consumption intentions under two distinct regimes: monetary easing and tightening cycles. Using data from low‐ and high‐income households, we assess both the magnitude and the dynamics of this relationship.

Risk return of forward contracting corn with crop insurance

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Forward contracting is a common pre‐harvest marketing strategy for row crops, with evidence suggesting higher prices during summer months due to embedded weather risk premiums. While aggressive forward contracting increases farmers' yield risk and potential non‐delivery penalties, crop revenue protection can help offset these financial burdens.
