(Tamkang University, 2025-02)The current work deals with initial boundary value parabolic problems with Preisach hysteresis whose the density functions are allowed to depend on the variable of space. The model contains nonlinear monotone operators in ...

Optimal monetary and fiscal policies to maximise non-parallel risk premia in sovereign bond markets (MDPI, 2024-11)In this paper, we analysed several emerging market (EM) and developed market (DM) sovereign yield curves to identify the proportion of parallel and non-parallel shifts over time. We found that non-parallel shifts are ...
-
(AIMS Press, 2024-07)A new mathematical model for the transmission dynamics and control of the Middle Eastern respiratory syndrome (MERS), a respiratory virus caused by MERS-CoV coronavirus (and primarily spread to humans by dromedary camels) ...
-
(Springer, 2024-08)This study focuses on students who are registered for the University of Pretoria’s academic development programme, the Four-year Programme (FYP). The programme was introduced as a gateway for students who are under-prepared ...
-
(Universidad de la Frontera, 2024-12)Please read abstract in the article.
-
(Springer, 2025-03)This study presents a wastewater-based mathematical model for assessing the transmission dynamics of the SARS-CoV-2 pandemic in Miami-Dade County, Florida. The model, which takes the form of a deterministic system of ...
-
(Springer, 2024-08-31)We present a Virtual Element MATLAB solver for elliptic and parabolic, linear and semilinear Partial Differential Equations (PDEs) in two and three space dimensions, which is coined VEMcomp. Such PDEs are widely applicable ...
-
(Elsevier, 2025-05)We study a system of coupled bulk-surface partial differential equations (BS-PDEs), describing changes in concentration of certain proteins (Rho GTPases) in a living cell. These proteins, when activated, are bound to the ...
-
(Oxford University Press, 2024-08)Please read abstract in article.
-
(MDPI, 2024-02)This note introduces a new class of preinvexity called (h1, h2)-Godunova-Levin preinvex functions that generalize earlier findings. Based on these notions, we developed Hermite-Hadamard, weighted Fejér, and trapezium ...

(MDPI, 2024-04)Please read abstract in the article.

(MDPI, 2024-12)We construct a new metapopulation model for the transmission dynamics and control of the Ebola Virus Disease (EVD) in an environment characterized by considerable migrations and travels of people. It is an extended ...
-
(MDPI, 2024-04-19)The aim of this paper is to introduce a new type of two-dimensional convexity by using totalorder relations. In the first part of this paper, we examine the Hyers–Ulam stability of two-dimensional convex mappings by using ...
-
(Springer, 2024-03)The vector or pest control is essential to reduce the risk of vector-borne diseases or crop losses. Among the available biological control tools, the sterile insect technique (SIT) is one of the most promising. However, ...
-
(Springer, 2025-03)A climate-based metapopulation malaria model is formulated by incorporating human travel between zones with varying climatic factors, effective and counterfeit drug treatments, and time-periodic parameters for the mosquito ...
-
(Elsevier, 2024-12)In this work, we present a mechanobiochemical model for two-dimensional cell migration which couples mechanical properties of the cell cytosol with biochemical processes taking place near or on the cell plasma membrane. ...
-
(Springer, 2024-10)We exhibit infinitely many semisimple varieties of semilinear De Morgan monoids (and likewise relevant algebras) that are not tabular, but which have only tabular proper subvarieties. Thus, the extension of relevance ...
-
(Elsevier, 2024-09)In this work, we study the dual effects of linear cross-diffusion and geometry on reaction–diffusion systems for pattern formation on rectangular domains. The spatiotemporal dynamics of the reaction–diffusion system with ...

(AOSIS, 2024-09-17)BACKGROUND : Many retirees in South Africa face the challenge of either outliving their retirement savings or living below their means. Studies suggest a ‘safe’ withdrawal rate of between 4% and 5%, which is below the ...
-
(AOSIS, 2024-05-31)BACKGROUND : This study focuses on diversifying fixed income attribution beyond yield and duration by identifying new risk premia applicable to various investment strategies. AIM : To identify cross-sectional bond risk ...
