Dynamical Analysis of an HIV Infection Model Including Quiescent Cells and Immune Response

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This research gives a thorough examination of a human immunodeficiency virus (HIV) infection model that includes quiescent cells and immune response dynamics in the host. The model, represented by a system of ordinary differential equations, captures the complex interaction between the host's immune response and viral infection.

Meta‐Metamodelling of Engineering Systems by Help of Abstract Mathematics

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The growing trend of automation in engineering significantly increases the complexity of engineering systems and necessitates a deeper understanding of the coupling of physical and cyber components interacting within the systems. A typical example of such a highly coupled system is an autonomous construction site, where robotic systems aim to ...

Superquadric Motion and Superquadric Hyperbolic Split Quaternion Algebra Via Gielis Formula

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Superquadrics are one of the most suitable geometric tools for modeling many complex shapes in nature. It is possible to model many objects, human figures, and living creatures in nature in a suitable way by means of superquadrics. On the other hand, quaternions are useful in mathematics, especially for computations involving three‐dimensional

Nonlinear Sequential Fractional Integro‐Differential Systems: Caputo‐Type Derivatives and Boundary Constraints

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In recent years, the study of sequential fractional differential equations (SFDEs) has become increasingly important in multiple domains of science and engineering. This work investigates a new class of boundary value problems (BVPs) characterized by nonlocal closed boundary conditions involving SFDEs with Caputo fractional integral operators.
