An optimal control problem for mosaic disease via Caputo fractional derivative

Alexandria Engineering Journal, 2022
In this research article, we derive an optimal control problem for the mosaic disease model by using the Caputo fractional derivatives. The natural microbial biostimulants (MBs) are very useful to improve the plant performance and protect plants from ...

ANALISIS KESTABILAN LOKAL TITIK EKUILIBRIUM MODEL EPIDEMI SEIV DENGAN PERTUMBUHAN LOGISTIK

Majalah Ilmiah Matematika dan Statistika, 2022
The SEIV model uses population growth which is assumed to follow logistical growth. The model is studied then analyzed. The analysis shows that the non-endemic (disease-free) equilibrium point is locally asymptotically stable when the basic reproduction ...

Social heterogeneity and the COVID-19 lockdown in a multi-group SEIR model

Computational and Mathematical Biophysics, 2021
The goal of the lockdown is to mitigate and if possible prevent the spread of an epidemic. It consists in reducing social interactions. This is taken into account by the introduction of a factor of reduction of social interactions q, and by decreasing ...

A Classification System for Hospital‐Based Infection Outbreaks

Computational and Mathematical Methods in Medicine, Volume 11, Issue 4, Page 297-311, 2010., 2010
Outbreaks of infection within semi‐closed environments such as hospitals, whether inherent in the environment (such as Clostridium difficile (C.Diff) or Methicillinresistant Staphylococcus aureus (MRSA) or imported from the wider community (such as Norwalk‐like viruses (NLVs)), are difficult to manage.

Data from: Sex-biased gene expression in dioecious garden asparagus (Asparagus officinalis)

, 2015
Sex chromosomes have evolved independently in phylogenetically diverse flowering plant lineages. The genes governing sex determination in dioecious species remain unknown, but theory predicts that the linkage of genes influencing male and female function

Khalouta transform and applications to Caputo-fractional differential equations

Frontiers in Applied Mathematics and Statistics
The paper aims to utilize an integral transform, specifically the Khalouta transform, an abstraction of various integral transforms, to address fractional differential equations using both Riemann-Liouville and Caputo fractional derivative.

Analysis of a Data‐Driven Vector‐Borne Dengue Transmission Model for a Tropical Environment in Bangladesh

International Journal of Differential Equations, Volume 2024, Issue 1, 2024.
Dengue is the most prominent arboviral infection known to humans, especially in tropical regions of the world like Bangladesh. This is often a tricky outbreak to deal with, given its nature of seasonality, and due to the impact of climate change, variations in the length of its on‐season have been observed.

Improving adherence to a daily PrEP regimen is key when considering long-time partnerships

Journal of Biological Dynamics
A population model of HIV that includes susceptible individuals not taking the pre-exposure prophylaxis (PrEP), susceptible individuals taking daily PrEP, and infected individuals is developed for casual partnerships, as well as monogamous and non ...

Stochastic modeling of group testing with random total sample size

Scientific African
In the classical Dorfman group testing procedure Dorfman (1943), a fixed population of size N is divided into k pools of equal size n . Each pool is tested: a negative result clears all n individuals, whereas a positive result triggers individual testing
