Convergence Results for Common Fixed Points of Nearly Nonexpansive Mappings
This paper aims to establish several convergence results for common fixed points of two nearly nonexpansive mappings by means of a modified S-iteration process. Specifically, we prove both strong and weak convergence theorems in uniformly convex Banach spaces.

A Digit-Based Discrete Dynamical System Generated by a Figure-Changing Transformation
Digit-based iterative processes often give rise to rich dynamical behavior despite being defined by simple arithmetic rules. In this paper, we investigate a figure-changing transformation acting on four-digit numbers, where each iteration is obtained by shifting digits and appending the digital…

Some remarks on G-nonexpansive and G-quasi nonexpansive mappings
Here, we discussed some relations between G-nonexpansive mappings and G−quasinonexpansive mappings and their structures. Further we obtained some convergence results of a sequence, defined by Schaefer iteration scheme for multi-valued Osilike-Berinde G-nonexpansive mapping in uniformly convex…

Nonlinear Contraction-Based Coupled Fixed Point Theorems in Partial b-Metric Spaces with Applications
In (Mediterr. J. Math. 11, 703–711, 2014), Shukla introduced the concept of partial b-metric spaces as a generalization of partial metric and b-metric spaces. The purpose of this article is to establish some coupled fixed point results for contractive mappings in a partial b-metric space. Examples…

Therapeutic Effects of Mangifera indica on Chronic Health Conditions: A Logistic Regression Analysis in Oyo State, Nigeria
In numerous developing nations, traditional medicine is one of the basics of health care due to limited access to conventional medical systems. Mangifera indica (Linn.) is an indigenous treatment for managing chronic illnesses. However, little quantitative evidence about the perceived effectiveness…

Fixed point approach for relation-theoretic contractive type mappings in F-metric spaces with application to boundary value problems
The aim of this article is to introduce the notion of F-metric spaces and establish some fixed point results for relation-theoretic contractive type mapping in a complete F-metric space. These contributions extend the existing literature on relation-theoretic mapping and fixed point theory. Through…

An Optimized hybrid one step method for numerical integration of second order initial value problems
This article presents an optimized hybrid one-step block method for the direct numerical integration of second-order initial value problems (IVPs) of the form y′′ = f (x,y,y′). The method is derived using a power series basis function through a collocation and interpolation technique, allowing for…

An Inventory Model for Non-Instantaneously Reasoned, Continuously Deteriorating Items under a Linear Demand Rate
This paper develops a deterministic economic order quantity (EOQ) model for a single deteriorating item under a linear, time-dependent demand rate D(t) = a+bt, where deterioration proceeds at a constant instantaneous rate θ applied to the on-hand inventory. Shortages are not permitted. The…

Classification of Injury Risk Among Basketball Players: A Statistical Perspective
Injuries are a major concern in basketball, often caused by fatigue, high training loads, and insufficient recovery. This study developed a predictive model using player data-including demographics, training intensity, recovery patterns, and fatigue levels-to assess injury risk. Among several…

Optimal fourth order iterative method for solving nonlinear equation
The principal objective of this work is to propose a fourth order scheme for solving a nonlinear equation. In terms of computational cost, per iteration, the fourth order method uses two evaluation of the function and one evaluation of first derivative. So the method has satisfied the Kung-Traub…

The basins of attraction for optimal fourth-eighth order methods
We developed a completely new, eighth- and fourth-order optimal approach for solving nonlinear equations in this study. With three function evaluations, the new methods’ convergence order is four; with four function evaluations, it is eight. Furthermore, according to the Kung-Traub hypothesis, it…

Trajectory Planning in Complex Environments for Static and Moving Obstacles
This paper presents a piecewise-linear approach for motion planning in uncertain environments punctured with static and moving obstacles. In such environments robots may encounter obstacles with unknown sizes, shapes, and locations. The probability of a robot colliding with an unknown obstacle…

A Mathematical Model for the Spread of Monkeypox in Uganda: An SIR Model with Demographic Effects
Monkeypox, a viral zoonotic disease caused by the monkeypox virus and primarily transmitted through close contact with infected animals and humans, poses a growing public health challenge, especially in endemic regions like Uganda. With its potential for human-tohuman transmission and an increasing…

Optimizing Control Measures for a Vector-Host Epidemic Model: A Mathematical Analysis
Malaria, Rift Valley Fever, Dengue Fever and West Nile Fever are vector-host infections that are endemic among most of the populations mainly across the tropical regions. As much as these diseases are treatable and preventable they have proved to be among the greatest attributes to mortality among…

Expanding the Horizons of Graph Theory: Rough Tree-Width, Hyperrough Structures, and Superhyperrough Generalizations
Rough set theory provides a formal framework for managing imprecise information by approximating subsets of a universe through lower and upper bounds derived from equivalence relations. This foundational idea has been extended to more expressive structures such as the Hyperrough Set and the…
