Factorizations of some lower triangular matrices and related combinatorial identities

, 2021
In this study, we investigate the connection between second order recurrence matrix and several combinatorial matrices such as generalized r-eliminated Pascal matrix, Stirling matrix of the first and of the second kind matrices.

Frequency-Dependent Competition Between Strains Imparts Persistence to Perturbations in a Model of Plasmodium falciparum Malaria Transmission

Frontiers in Ecology and Evolution, 2021
In high-transmission endemic regions, local populations of Plasmodium falciparum exhibit vast diversity of the var genes encoding its major surface antigen, with each parasite comprising multiple copies from this diverse gene pool. This strategy to evade

Tops as building blocks for G 2 manifolds

Journal of High Energy Physics, 2017
A large number of examples of compact G 2 manifolds, relevant to supersymmetric compactifications of M-Theory to four dimensions, can be constructed by forming a twisted connected sum of two building blocks times a circle.

Network conduciveness with application to the graph-coloring and independent-set optimization transitions. [PDF]

PLoS ONE, 2010
BACKGROUND: Given an undirected graph, we consider the two problems of combinatorial optimization, which ask that its chromatic and independence numbers be found.

Genomic Analysis of SARS-CoV-2 Alpha, Beta and Delta Variants of Concern Uncovers Signatures of Neutral and Non-Neutral Evolution

Viruses, 2022
Due to the emergence of new variants of the SARS-CoV-2 coronavirus, the question of how the viral genomes evolved, leading to the formation of highly infectious strains, becomes particularly important. Three major emergent strains, Alpha, Beta and Delta,

Applications of Combinatorial Analysis to the Calculation of the Partition Function of the Ising Model [PDF]

, 2009
The research work discussed in this thesis investigated the application of combinatorics and graph theory in the analysis of the partition function of the Ising Model. Chapter 1 gives a general introduction to the partition function of the Ising Model

ANALYTICAL APPROACH TO DESCRIPTION OF SOME C0MBINATORIAL AND NUMBER-THEORETIC COMPUTATIVE ALGORITHMS [PDF]

, 1999
We discuss the theme on translating different descriptions of computative algorithms into high-level programming languages, enumerate some advantages of analytical descriptions and demonstrate that logical functions may be used effectively to create ...
