(Elsevier, 2022-05)Please read abstract in the article.
-
(MDPI, 2021-04-24)This paper deals with monic orthogonal polynomials orthogonal with a perturbation of classical Meixner–Pollaczek measure. These polynomials, called Perturbed Meixner–Pollaczek polynomials, are described by their weight ...
-
(NISC Pty (Ltd) and Informa Limited (trading as Taylor and Francis Group), 2021)This paper considers the recent underperformance of the equal weighted portfolio of South African Top 40 stocks relative to the market capitalisation weighted portfolio. It highlights the impact of the increased concentration ...

(Elsevier, 2021-11)Please read abstract in the article.
-
(Elsevier, 2021-04)A comparative performance analysis of two spectral methods on the hyperchaotic finance system (HCFS) and the cryptocurrency pricing problem (CPP) is proposed. The first approach uses a differentiation matrix, the second ...
-
(MDPI, 2021-06-10)In this paper, the Heston–Nandi futures option pricing model is applied to Bitcoin futures options. The model prices are compared to market prices to give an indication of the pricing performance. In addition, a multivariate ...
-
(Taylor and Francis Group, 2021-04-19)This article focuses on the unique contribution of the QT-clicker regarding formative and summative assessment in a large flipped first year statistics module. In this module, the flipped classroom as pedagogical model ...
-
(Sciendo, 2021-06)In this paper, authors establish a new identity for a differentiable function using generic integral operators. By applying it, some new integral inequalities of trapezium, Ostrowski and Simpson type are obtained. Moreover, ...

(Springer, 2021-01)Please read abstract in the article.
-
(Taylor and Francis, 2021)Although pneumococcal vaccines are quite effective in reducing disease burden, factors such as imperfect vaccine efficacy and serotype replacement present an important challenge against realizing direct and herd protection ...

(University of Isfahan, 2021-03)Please read abstract in the article.
-
(Springer, 2021-03)In this note we provide a new proof of the Tikhonov theorem for the infinite time interval and discuss some of its applications.
-
(Taylor and Francis, 2022)A classical theorem on character degrees states that if a finite group has fewer than four character degrees, then the group is solvable. We prove a corresponding result on character values by showing that if a finite group ...
-
(Institute of Electrical and Electronics Engineers, 2022-06)Recurrent neural networks (RNNs) are successfully employed in processing information from temporal data. Approaches to training such networks are varied and reservoir computing-based attainments, such as the echo state ...
-
(KeAi Communications, 2021-09-09)Multiple effective vaccines are currently being deployed to combat the COVID-19 pandemic, and are viewed as the major factor in marked reductions of disease burden in regions with moderate to high vaccination coverage. ...

It became the most important public health challenge facing ...
-
(Academy of Science of South Africa, 2022-03)An important topic for retirees is determining how much they can safely withdraw from their retirement savings: draw too much from their retirement fund and risk outliving their retirement savings, or draw too little and ...
-
(Cambridge University Press, 2022-04)In this paper, we study the structure of finite groups G=AB which are a weakly mutually sn -permutable product of the subgroups A and B, that is, A permutes with every subnormal subgroup of B containing A∩B and B permutes ...
