Distribution of Purines and Pyrimidines over miRNAs of Human, Gorilla and Chimpanzee
, 2017 Meaningful words in English need vowels to break up the sounds that consonants make. The Nature has encoded her messages in RNA molecules using only four alphabets A, U, C and G in which the nine member double-ring bases (adenine (A) and Guanine (G)) are

Journal of Mathematics, Volume 2026, Issue 1, 2026.This study presents the SEIAR epidemic model within the Caputo time‐fractional derivative of order α and a diffusion operator in one dimension. The modified formulation also contains two measures of effort; u1, which concerns the adoption of infection prevention measures, such as taking health precautions in gatherings and working to decrease social ...

Global properties of virus dynamics with B-cell impairment
Open Mathematics, 2019 In this paper we construct a class of virus dynamics models with impairment of B-cell functions. Two forms of the incidence rate have been considered, saturated and general. The well-posedness of the models is justified.

Evaluation of TB elimination strategies in Canadian Inuit populations: Nunavut as a case study
Infectious Disease Modelling, 2022 Tuberculosis (TB) continues to disproportionately affect Inuit populations in Canada with some communities having over 300 times higher rate of active TB than Canadian-born, non-Indigenous people. Inuit Tuberculosis Elimination Framework has set the goal

Discrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.This work will study an optimal control problem describing the two‐strain SEIR epidemic model. The model studied is in the form of six nonlinear differential equations illustrating the dynamics of the susceptible and the exposed, the infected, and the recovered individuals.

Stability property of the prey free equilibrium point
Open Mathematics, 2019 We revisit a prey-predator model with stage structure for predator, which was proposed by Tapan Kumar Kar. By using the differential inequality theory and the comparison theorem of the differential equation, we show that the prey free equilibrium is ...

Growth rate, evolutionary entropy and ageing across the tree of life
Journal of Biological Dynamics, 2023 The growth rate of a population serves as a measure of its Darwinian fitness, while its sensitivity indicates the intensity of selection. Generally, the sensitivity of r decreases with age, resulting in an expected increase in population mortality over ...

Journal of Mathematics, Volume 2025, Issue 1, 2025.In this study, we develop a compartmental mathematical model to offer a thorough understanding of the dynamics of monkeypox viral transmission. We examine the sensitivity of the epidemic model to the fundamental reproduction number (R0). We also utilize an expanded Euler technique to scrutinize the dynamics of monkeypox transmission between humans and ...
