Entropy measures of distance matrix [PDF]
Discrete Mathematics Letters, 2022 Bonchev and Trinajstic defined two distance based entropy measures to measure the molecular branching of molecular graphs in 1977 [Information theory, distance matrix, and molecular branching, J. Chem. Phys., 38 (1977), 4517–4533]. In this paper we use these entropy measures which are based on distance matrices of graphs.

Ergodicity of project management system
Trudy Odesskogo Politehničeskogo Universiteta, 2015 The structures effectiveness of project management depends on two factors: parametric properties that reflect the properties of separate elements (or processes), structural properties of system that reflect the influence of elements interconnections on ...

ON DETERMINING THE DISTANCE SPECTRUM OF A CLASS OF DISTANCE INTEGRAL GRAPHS [PDF]
Journal of Algebraic Systems, 2023 The distance eigenvalues of a connected graph $G$ are the eigenvalues of its distance matrix$D(G)$. A graph is called distance integral if all of itsdistance eigenvalues are integers.Let $n$ and $k$ be integers with $n>2k, k\geq1$.

Analysis of amino acids network based on transition and transversion mutation of codons [PDF]
Network Biology, 2021 In this paper, we have developed a network of 20 amino acids based on a distance matrix of amino acids. This distance matrix is obtained by considering the transition and transversion mutation of codons.

Squared distance matrices of trees with matrix weights
AKCE International Journal of Graphs and Combinatorics, 2023 Let T be a tree on n vertices whose edge weights are positive definite matrices of order s. The squared distance matrix of T, denoted by Δ, is the ns × ns block matrix with [Formula: see text], where d(i, j) is the sum of the weights of the edges in the ...

Algebraic structures and distance based analysis of genetic code [PDF]
Network Biology, 2023 This paper explores the genetic code's algebraic structures associated with the four mRNA (or DNA) bases A, G, C, and U. We have obtained quotient group structures of codons by considering the transition and substitution mutation. In these quotient group

On the distance energy of k-uniform hypergraphs
Special Matrices, 2023 In this article, we extend the concept of distance energy for hypergraphs. We first establish a relation between the distance energy and the distance spectral radius.
