We developed a dengue epidemic model by considering hospitalized class and harmonic
mean incidence rate. A qualitative study of the proposed model was conducted. The Basic …

The aim of the present study is to consider a heroin epidemic model with age-structure only
in the active heroin users. The model was formulated with the help of available literature on …

A delay epidemic model is developed, with the susceptible population divided into three
subclasses. In the main model, the well-known “Michaelis Menten Equation” is utilized to …

This article deals with qualitative analysis of a smoking model and provides parametric
conditions for controlling diseases under the influence of smoking. The model is obtained by …

In this paper, a new kind of mathematical modeling is studied by providing a five-
compartmental system of differential equations with respect to new hybrid generalized fractal …

In this study, we aim to comprehensively investigate a drinking model connected to
immigration in terms of Atangana-Baleanu derivative in Caputo type. To do this, we firstly …

In this study, a smoking and heroin co-abuse model is proposed for the first time in the
literature. To research the dynamics and impacts of smoking-heroin co-morbidity in the …

In this paper, we focus on the study of the dynamics of a certain age structured epidemic
model. Our aim is to investigate the proposed model, which is based on the classical SIR …

Malaria is a typical mosquito borne disease and one of the oldest human diseases, which is
still one of the most serious threats to public health. In the process of prevention and control …

In this paper, we are concerned with a delayed smoking model in which the population is
divided into five classes. Sufficient conditions guaranteeing the local stability and existence …
