An investigation was conducted on the green synthesis of gold nanoparticles (AuNPs) using aqueous Telfairia occidentalis leaf extract as both the reducing and stabilizing agent. Following preliminary …

The adverse effects associated with conventional cancer therapies have intensified the search for anticancer agents with fewer side effects. One approach involves the synthesis of organotin(IV) …

Three Schiff base ligands derived from condensation of ethylenediamine with benzaldehyde, salicylaldehyde, and vanillin, namely (1E,1'E)-N,N'-(ethane-1,2-diyl)bis(1-phenylmethanimine) (BBE), …

Conversational agents for low-resource languages (LRLs), such as Igbo, face major challenges, including limited annotated data, code-switching, and weak contextual coherence in multi-turn dialogue. This …

The Model Context Protocol (MCP) standardizes connections between large language model applications and external tools and data. Its capability negotiation, dynamic discovery, insertion of tool results …

Nigeria faces challenges in the accurate diagnosis of respiratory diseases such as tuberculosis (TB), pneumonia, and COVID-19 because of limited radiology resources and stringent patient-privacy …

This study evaluates an explainable ensemble in which Convolutional Neural Network and Bidirectional Long Short-Term Memory feature extractors feed a Random Forest classifier, applied under one …

Plant diseases threaten agricultural productivity, and automated image analysis can support early identification of visible disease symptoms. This study introduces HybOptic-CNN, a convolutional neural …

Reservoir development in the Niger Delta is affected by geological uncertainties arising from complex stratigraphic architecture, high-frequency sea-level changes, fault-controlled subsidence, and variable …

For a finite commutative ring R, the nil clean graph G_N(R) is the undirected simple graph with the  elements of R as its vertex set, where two distinct vertices x and y are …

Accurate forecasting of infectious disease spread is essential for public health decision-making. This study compares mechanistic susceptible-exposed-infectious-removed (SEIR) models, machine-learning …

Network-security planning frequently depends on judgments that are imprecise, incomplete, and sometimes internally conflicting. Conventional numerical decision models are effective when assessments are …

This paper proposes a new ranked set sampling (RSS) design, termed modified neoteric RSS (MNRSS), for efficient estimation of the population mean and variance. The proposed method extends the neoteric RSS …

A fresh class of hybrid special polynomials, termed the Bell-enriched Appell-lambda-polynomials, is constructed through the discrete convolution of Bell-based lambda-polynomials with the Appell sequence. A …

Artificial intelligence (AI)-enabled telemedicine platform selection involves multiple conflicting criteria and uncertain expert judgments. Conventional multi-criteria decision-making (MCDM) approaches …

The principal objective of this article is to establish new and refined variants of Hermite--Hadamard- and Fej'{e}r-type integral inequalities in the interval-valued setting by exploiting the auxiliary …

The spanning tree of a graph is obtained when all vertices of a graph are connected in such a way that no cycle is formed. This work proposes a new algorithm that, at each round, selects a maximal …

This article introduces a new concept of complex single-valued neutrosophic sets (CSVNS) and explores their basic set-theoretic characteristics. Based on this framework, an approach to visual analytics …

Skewed distributions have an additional shape parameter that represents the direction of the asymmetry in the density. If skewness in observations is ignored, statistical inferences based on symmetric …

With the ongoing expansion of healthcare services, the amount of medical waste (MW) has been rising steadily, placing increasing pressure on environmental systems and public health. Identifying an …

This study investigates the existence, uniqueness, and Ulam--Hyers stability of solutions to nonlinear fractional differential equations (NFDEs) involving the Caputo fractional derivative. We extend and …

This article develops a factorization-based operator framework for two-variable discrete Gould--Hopper--Appell polynomials within  Delta_(delta) -calculus. Following the Infeld--Hull factorization …

When strong causality fails, the Alexandrov topology of a spacetime is strictly coarser than the manifold topology. Since pathologies confined to sets of measure zero are routinely disregarded in …

In this study, we analyze a cosmological model based on Tsallis Holographic Dark Energy (THDE) in Kaluza--Klein (KK) spacetime within f(R,T) gravity. Exact solutions to the field …
