Abstract: We obtain the characteristic polynomials and a number of spectral-based indices such as the Riemann-Zeta functional indices and spectral entropies of n-dimensional hypercubes using recursive Hadamard transforms....

While the square root of Dirac's δ is not defined in any standard mathematical formalism, postulating its existence with some further assumptions defines a generalized function called γ ( x ) which permits a quasi-classical treat...

In this work, a new version of Rényi's divergence is presented. The expression obtained is used as a tool to identify molecules that could share some chemical or structural properties, and a data basis set of 1641 molecules is used in this...
Biochemical and phylogenetic networks-II: X-trees and phylogenetic trees [0.03%]

The present study, which is a continuation of the previous paper, augments a recent work on the use of phylogenetic networks. We develop techniques to characterize the topology of various X-trees and binary trees of biological and phylogene...

We have obtained graph-theoretically based topological indices for the characterization of certain graph theoretical networks of biochemical interest. We have derived certain distance, degree and eccentricity based topological indices for v...

A new tool of the classification of DNA sequences is introduced. The method is based on 2D-dynamic graphs and their descriptors. Using the descriptors created by centers of masses, moments of inertia, angles between the x axis and the princ...

New approaches aiming at a detailed similarity/dissimilarity analysis of DNA sequences are formulated. Several corrections that enrich the information which may be derived from the alignment methods are proposed. The corrections take into a...
A complexity-based measure and its application to phylogenetic analysis [0.03%]

In this article, we propose two well-defined distance metrics of biological sequences based on a universal complexity profile. To illustrate our metrics, phylogenetic trees of 18 Eutherian mammals from comparison of their mtDNA sequences an...
Phylogenetic inference from binary sequences reduced by primary DNA sequences [0.03%]
由初级DNA序列减少的二进制序列推断系谱基因组关系

Given a bi-classification of nucleotides, we can obtain a reduced binary sequence of a primary DNA sequence. This binary sequence will undoubtedly retain some biological information and lose the rest. Here we want to know what kind of and h...

Recent studies have found an unusual way of dissociation in formaldehyde. It can be characterized by a hydrogen atom that separates from the molecule, but instead of dissociating immediately it roams around the molecule for a considerable a...
