A Study on the Nourishing Number of Graphs and Graph Powers

open access: yesMathematics, 2015
Let \(\mathbb{N}_{0}\) be the set of all non-negative integers and \(\mathcal{P}(\mathbb{N}_{0})\) be its power set. Then, an integer additive set-indexer (IASI) of a given graph \(G\) is defined as an injective function \(f:V(G)\to \mathcal{P}(\mathbb{N}

The Euclid Algorithm is totally gaussian [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We consider Euclid’s gcd algorithm for two integers $(p, q)$ with $1 \leq p \leq q \leq N$, with the uniform distribution on input pairs. We study the distribution of the total cost of execution of the algorithm for an additive cost function $d$ on the ...

Strong Integer Additive Set-valued Graphs: A Creative Review [PDF]

open access: yes, 2015
For a non-empty ground set $X$, finite or infinite, the {\em set-valuation} or {\em set-labeling} of a given graph $G$ is an injective function $f:V(G) \to \mathcal{P}(X)$, where $\mathcal{P}(X)$ is the power set of the set $X$. A set-indexer of a graph $

OASIS +: leveraging machine learning to improve the prognostic accuracy of OASIS severity score for predicting in-hospital mortality

open access: yesBMC Medical Informatics and Decision Making, 2021
Background Severity scores assess the acuity of critical illness by penalizing for the deviation of physiologic measurements from normal and aggregating these penalties (also called “weights” or “subscores”) into a final score (or probability) for ...

Additive energies on discrete cubes

open access: yesDiscrete Analysis, 2023
One definition of additive combinatorics is that it is the study of subsets of (usually Abelian) groups. Two much studied parameters associated with a subset $A$ are the size of its sumset $A+A=\{a+b:a,b\in A\}$ (or the product set $A.A=\{a.b:a,b\in A\}$

Approximate modularity: Kalton's constant is not smaller than 3 [PDF]

open access: yes, 2020
Kalton and Roberts [Trans. Amer. Math. Soc., 278 (1983), 803--816] proved that there exists a universal constant $K\leqslant 44.5$ such that for every set algebra $\mathcal{F}$ and every 1-additive function $f\colon \mathcal{F}\to \mathbb R$ there exists

Multifractal analysis of the irregular set for almost-additive sequences via large deviations [PDF]

open access: yes, 2015
In this paper we introduce a notion of free energy and large deviations rate function for asymptotically additive sequences of potentials via an approximation method by families of continuous potentials.

An alternative methodological approach to value analysis of regions, municipal corporations and clusters

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
The paper deals with theoretical conception of value analysis of regions, municipal corporations and clusters. The subject of this paper is heterodox approach to sensitivity analysis of finite set of variables based on non-additive measure.

Dieudonné's theorem for non-additive set functions

open access: yesJournal of Mathematical Analysis and Applications, 2010
\({\mathcal A}\) is an algebra of subsets of a set \(X\), with a join semilattice \({\mathcal F} \subseteq{\mathcal A}\) and a meet semilattice \({\mathcal G} \subseteq{\mathcal A}\), \({\mathbf S} = ({\mathcal S},{\mathcal U})\) is a complete Hausdorff uniform space with an arbitrarily fixed point \(e\) and \(\mathcal{U}[e]\) a fundamental system of \(

The association of lncRNA SNPs and SNPs‐environment interactions based on GWAS with HBV‐related HCC risk and progression

open access: yesMolecular Genetics & Genomic Medicine, 2021
Background Long non‐coding RNA (lncRNA) plays an essential role in hepatitis B virus‐related hepatocellular carcinoma (HBV‐related HCC) occurrence and development. Single nucleotide polymorphism (SNP) may affect HBV‐related HCC susceptibility by altering
