Policy lapse is a vital component in life insurance as it affects future pricing and impacts the solvency of the life insurer. Accurate prediction of lapse will help the insurers to implement personalised retention strategies ...
We propose a mathematical model for the transmission dynamics of enterovirus. We prove
that if the basic reproduction number R0 1, a suitable Lyapunov function is used to
establish the global stability of the disease ...
Lassa fever is an infectious and zoonotic disease with incidence ranging between a hundred
to three hundred thousand cases, with approximately ve thousand deaths reported yearly
in West Africa. This disease has become ...
The premise of this study is that price fluctuations amongst exchange rates, stock and
commodities markets are dynamically linked. The study models monthly price changes
amongst these markets in 20 highest World Bank ...
The original two-variable integrodifferential equation for few-body systems is mod ified by introducing boundary conditions in the radial and angular domains. The
accuracy of the adiabatic approximation in solving this ...
The underperforming agricultural sector in Sub-Saharan Africa (SSA) has left African countries with
insufficient food production in the face of challenges related to climate change, diseases and
increasing population ...
Nowadays human activities produce massive amounts of data everyday. It is estimated that 2.5
quintillions bytes of data are produced daily. The ability to analyse and interpret such data, usually
referred to as ‘big ...
Metal-organic frameworks (MOFs) are gaining popularity as a new electrode material for
supercapacitor applications, due to their large specific surface area, excellent tunability and unique
pore characteristics. Yet, ...
The physics of loosely-bound and halo nuclei is very important in the enhancement
of knowledge about the complete nature of strong interactions in general, and nuclear
forces in particular. Although such nuclei are widely ...
Abstract
Lassa fever is an infectious and zoonotic disease with incidence ranging between a hundred to three hundred thousand cases, with approximately five thousand deaths reported yearly in West Africa. ...
Substantial progress has been made in the studies of loosely-bound nuclei, however there are many issues about the properties of these nuclei that have not been resolved yet. For example nuclear decay, nuclear reactions ...
In this work we analyse fusion cross-section (σF ) in different projectile target systems.
Collision systems can result in different reactions such as elastic/ inelastic scattering, fu sion and fission reactions to name ...
HIV/AIDS continues to be a huge global burden having claimed million lives worldwide. It
targets the immune system and defence mechanisms against infections such as the human pa-
pillomavirus(HPV). HPV can be classifi ...
In this contribution the sinc basis functions are used to numerically solve the
Schrödinger equation in one and two dimensions for a number of potentials.
The calculations are done using the Python and Numpy modules. ...
Let L be a zero-dimensional frame and ZL be the ring of continuous integer-valued functions on L. We associate with each sublocale of L, the Banaschewski compacti cation of L, an ideal of ZL, and study the behaviour of ...
Multivariate longitudinal ordinal data are collected for studying the dependence between
multivariate ordinal outcomes, the changes over time and associated determinant factors. This
emanates from the interdependence ...
In this time of global health issues, there are out there many viruses that are shaking the world, including the
chikungunya virus, human immunodeficiency virus, corona virus, ebola virus and zika virus.
A metapopulation ...
Rural and urban learners from primary and secondary schools participate in science fairs all over the world, but their performance differs. To investigate the dynamics influencing the performance of rural and urban learners ...
The conventional approach in determining HIV risk factors fails to consider the influence behavioural and biological factors may have when modelled jointly. This study investigates the extent of influence behavioural and ...
Abstract
In this research, we study a general class of variable order integro-differential equations (VO-IDEs). We propose a numerical scheme based on the shifted fifth-kind Chebyshev polynomials (SFKCPs). ...
