A modified HIV model with Beddington–DeAngelis incidence and cure rate [PDF]
Scientific ReportsThis study presents a refined within-host human immunodeficiency virus (HIV) dynamics model that integrates several biologically relevant mechanisms often treated in isolation. The model incorporates a Beddington–DeAngelis functional response to describe

Solution of Inhomogeneous Fractional Differential Equations with Polynomial Coefficients in Terms of the Green’s Function, in Nonstandard Analysis [PDF]
Mathematics, 2021 Discussions are presented by Morita and Sato in Mathematics 2017; 5, 62: 1–24, on the problem of obtaining the particular solution of an inhomogeneous ordinary differential equation with polynomial coefficients in terms of the Green’s function, in the framework of distribution theory.

Grilliot's trick in Nonstandard Analysis [PDF]
Logical Methods in Computer Science, 2017 The technique known as Grilliot's trick constitutes a template for explicitly defining the Turing jump functional $(\exists^2)$ in terms of a given effectively discontinuous type two functional. In this paper, we discuss the standard extensionality trick:

Describing limits of integrable functions as grid functions of nonstandard analysis [PDF]
Partial Differential Equations and Applications, 2021 AbstractIn functional analysis, there are different notions of limit for a bounded sequence of$$L^1$$L1functions. Besides the pointwise limit, that does not always exist, the behaviour of a bounded sequence of$$L^1$$L1functions can be described in terms of its weak-$$\star $$⋆limit or by introducing a measure-valued notion of limit in the sense of ...

Body response to primary joint replacement after proximal femur injuries in patients with an increased body mass index (preliminary study) [PDF]
Гений oртопедии, 2020 Introduction Injuries of the proximal femur remains a significant problem of management in the elderly persons. The traditional approach comprising osteosynthesis of bone fragments is a method of choice in standard situations but showed to be ...

Local analysis of nonstandard $C^∞$ functions of pre-distributional type [PDF]
Annales Polonici Mathematici, 1984 The authors define pre-distributions as equivalence classes of non- standard \(^*C^{\infty}\) functions, and analyze the classes of the so- called K-pre-distributions. Discrete oscillation, essential oscillation and other properties are defined in the monad of a standard point.

Time averaging for functional differential equations
Journal of Applied Mathematics, 2003 We present a result on the averaging for functional differential equations on finite time intervals. The result is formulated in both classical mathematics and nonstandard analysis; its proof uses some methods of nonstandard analysis.

On Some Types of Functions in Nonstandard Analysis
Science Journal of University of Zakho, 2016 In this paper, by using some nonstandard concepts given by Robinson and axiomatized by Nelson we study the behavior of functions defined on a discrete intervals, whose points are of infinitesimal distances. This study leads to introduce and define some new types of functions in nonstandard analysis and we get some nonstandard results for different ...
