(American Institute of Mathematical Sciences, 2020-03)Ginzburg-Landau equation has a rich record of success in describing a vast variety of nonlinear phenomena such as liquid crystals, superfluidity, Bose-Einstein condensation and superconductivity to mention a few. Fractional ...
-
(Actuarial Society of South Africa, 2019)We analyse and discuss the use of an equal-weighted index as an alternative to the market capitalisation weighted (cap-weighted) index as a benchmark for active equity portfolios in the South African equity market. Our ...
-
(Actuarial Society of South Africa, 2019)It is now an accepted fact that the majority of financial markets worldwide are neither normal nor constant, and South Africa is no exception. One idea that can be used to understand such markets and has been gaining ...
-
(Elsevier, 2020)A graph property is a class of graphs which is closed under isomorphisms. Some properties are also closed under one or more specified constructions that extend any graph into a supergraph containing the original graph as ...
-
(Taylor and Francis, 2022)We derive a representation for dynamic capital allocation when the underlying asset price process includes extreme random price movements. Moreover, we consider the representation of dynamic risk measures defined under ...
-
(Elsevier, 2020-08)Cocoa mirid, Sahlbergella singularis, is known to be one of the major pests of cocoa in West Africa. In this paper, we consider a biological control method, based on mating disrupting, using artificial sex pheromones, and ...
-
(Springer, 2020-07)Recent dramatic declines in global malaria burden and mortality can be largely attributed to the large-scale deployment of insecticidal-based measures, namely long-lasting insecticidal nets (LLINs) and indoor residual ...
-
(Nature Research, 2019-07)Analytical and statistical stochastic approaches are used to model the dispersion of monogenic variants through large populations. These approaches are used to quantify the magnitude of the selective advantage of a monogenic ...
-
(University of Free State, 2019-11)Visual literacy is defined as competencies that enable an individual to understand, interpret, use, generate, and evaluate visual images or messages. The role of visual literacy in teaching mathematics is to enhance ...

(Elsevier, 2020-10)Please read abstract in the article.
-
(Elsevier, 2019-06)Although the widespread use of indoors residual spraying (IRS) and insecticides treated bednets (ITNs; later replaced by long-lasting insecticidal nets (LLINs)) has led to a dramatic reduction of malaria burden in endemic ...
-
(Springer, 2020-07)In this paper a full description of order isomorphisms between effect algebras of atomic JBW-algebras is given. We will derive a closed formula for the order isomorphisms on the effect algebra of type I factors by proving ...
-
(MDPI Open Access Journals, 2019)The purpose of this paper is to introduce af -proximal H-contraction of the first and second kind in the setup of complete fuzzy metric space and to obtain optimal coincidence point results. The obtained results unify, ...
-
(MDPI Open Access Journals, 2019)We present fixed points results of multivalued Prešić type k-step iterative mappings satisfying generalized weakly contraction conditions in metric spaces. An example is presented to support the main result proved herein. ...
-
(Cogent OA, 2019-11-01)Maximising returns is often the primary goal of asset management but managing and mitigating portfolio risk also plays a significant role. Successful active investing requires outperformance of a benchmark through skillful ...
-
(American Institute of Physics, 2019-07-24)The FitzHugh-Nagumo equation has various applications in the fields of flame propagation, logistic population growth, neurophysiology, autocatalytic chemical reaction and nuclear theory. In this work, we construct three ...
-
(Biomath Forum, 2019-01-23)Crop host-pathogen interaction have been a main issue for decades, in particular for food security. In this paper, we focus on the modeling and long term behavior of soil-borne pathogens. We first develop a new ...
-
(Ovidius University, Constanta, 2019)The aim of this paper is to introduce Ciric-Suzuki type quasi-contractive multivalued operators and to obtain the existence of fixed points of such mappings in the framework of b-metric spaces. Some examples are presented ...
-
(Elsevier, 2019-11)Please read abstract in the article.

(Taylor and Francis, 2019)A new deterministic mathematical model for the transmission dynamics of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is proposed and fully analyzed. The presented model exhibits a unique endemic equilibrium and ...
