Majorization Inequalities for n-Convex Functions with Applications to 3-Convex Functions
MathematicsIn this paper, we study majorization-type inequalities for n-convex (specifically 3-convex) functions. Numerous papers deal with such integral inequalities, in which n-convex functions are defined on compact intervals and nonnegative measures are used in

Examining the relationship between corporate governance and bank performance in Bangladesh
South African Journal of Business Management, 2015 Previous research has studied the impact of corporate governance on bank performance, but only a few aspects of the impact were reported. The present study develops a unique corporate governance index to provide a comprehensive measure of corporate ...

Stable Community Detection in Signed Social Networks
, 2022 IEEE Community detection is one of the most fundamental problems in social network analysis, while most existing research focuses on unsigned graphs. In real applications, social networks involve not only positive relationships but also negative ones. It

Link prediction algorithm in signed networks based on clustering coefficient and sign influence
四川大学学报. 自然科学版, 2021 In order to achieve the dual goals of link prediction and sign prediction in signed social networks quickly and accurately, a link prediction algorithm is proposed based on the clustering coefficient of common neighbor nodes and the influence of the sign

On the Feynman–Kac semigroup for some Markov processes
Modern Stochastics: Theory and Applications, 2015 For a (non-symmetric) strong Markov process X, consider the Feynman–Kac semigroup \[{T_{t}^{A}}f(x):={\mathbb{E}}^{x}\big[{e}^{A_{t}}f(X_{t})\big],\hspace{1em}x\in {\mathbb{R}}^{n},\hspace{2.5pt}t>0,\] where A is a continuous additive functional of X ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Regularized spectral methods for clustering signed networks
, 2021 International audienceWe study the problem of k-way clustering in signed graphs. Considerable attention in recent years has been devoted to analyzing and modeling signed graphs, where the affinity measure betweennodes takes either positive or negative ...
