Hypertension has continued to significantly affect morbidity and mortality rate, especially in developing countries like Nigeria. This study assessed Awareness and Behavioral Responses to Public Health Interventions for…
Soft set theory is a parameterized framework for the representation of uncertainty in situations where the available information is incomplete, qualitative, or difficult to encode by a probability distribution or member…
This paper presents a unified coefficient-recurrence framework for obtaining series solutions of second-order linear ordinary differential equations with variable coefficients. The standard power-series method, applicab…
Loanwords are an integral part of language development, particularly in multilingual societies where speakers are in constant contact with other languages. As languages evolve, lexical items are borrowed to meet new com…
Financial-market dynamics are inherently uncertain, and stochastic differential equations provide a natural framework for assessing the evolution of investment wealth under such conditions. This study formulates two sto…
Uncertainty in stock-market conditions makes the quantitative assessment of corporate investment portfolios an important problem in financial modelling. This study develops a system of stochastic differential equations …
Contraceptive access and informed use are essential components of reproductive health, enabling women to prevent unintended pregnancies, achieve desired birth spacing, and exercise informed reproductive choices. Despite…
The transition to post-quantum cryptography creates a mathematical decision problem in which security strength, algebraic structure, key and ciphertext sizes, execution time, memory demand, implementation complexity, an…
Prostate cancer remains an important cause of cancer-related morbidity and mortality among men, while late presentation continues to undermine early detection and treatment outcomes in many low- and middle-income settin…
Plasmodium falciparum</em>, the most virulent human malaria parasite, possesses a highly regulated genome that supports survival, adaptation, virulence, drug resistance, developmental switching, and stress respons…
The quality of school leadership and the precision with which teaching responsibilities are widely acknowledged as determinants of educational success. This research explored the interplay between principals' communicat…
To assess immune recovery among HIV patients undergoing antiretroviral therapy (ART), it is essential to monitor the CD4 cell count. Optimizing patient management is critical for understanding CD4 progression and its de…
The 2024 #EndBadGovernance protests in Nigeria emerged amid severe economic hardship, rising food prices, currency depreciation, unemployment, and declining confidence in public institutions. This paper develops a nonli…
This paper develops a substantially expanded computational and visual study of symmetric prime-pair distributions around even integers. For an even integer $2n$, a symmetric prime pair $(p_1,p_2)$ satisfies $p_1+p_2=2n$…
Nonlinear Volterra integral equations (VIEs) of the second kind arise in numerous physical contexts, including nonlinear heat conduction with memory, viscoelasticity, and population dynamics. However, when the kernel sa…
Free inverse semigroups constitute one of the fundamental structures in modern semigroup theory, providing the universal inverse-semigroup analogue of free groups and free semigroups while offering a natural algebraic f…
The increasing digitalisation of primary education has created new opportunities for instructional improvement while also exposing teachers to technology-related pressures that may weaken classroom control and pupils' l…
This study compared the effects of cooperative and problem-based teaching methods on students’ psychomotor skills performance in Motor Vehicle Mechanics Works in technical colleges in Akwa Ibom State, Nigeria. A q…
We study nonlinear Volterra integral equations in uniformly convex Banach spaces $L^p(\Omega)$ $(1
Dengue fever is a mosquito-borne viral disease that remains a major public health concern in tropical and subtropical regions. This study presents a seven-compartment nonlinear differential equation model comprising fou…
Accurate data-driven models for molecular dynamics must generate stable long-horizon predictions while providing uncertainty estimates that remain consistent with the principles of statistical mechanics. Motivated by th…
This study develops and compares three mathematical frameworks for modelling monthly inflation dynamics in Nigeria: an autoregressive integrated moving-average model, a Prophet additive forecasting model, and a finite-s…
Option pricing models are central to financial risk management and derivatives trading. The Black-Scholes-Merton (BSM) model provides closed-form solutions but relies on constant parameters, while numerical methods such…
This study develops a new, reproducible framework for analysing a transformed monthly price scenario associated with Lafarge Africa Plc. Unlike polynomial-trend and simple present-value approaches, the proposed methodol…
In this paper, the Black-Scholes model of put option were investigated on the share prices of Fidelity, Access and Merged Banks; which paved way to obtain put option close form prices. The table results were presented o…
Crude oil pollution reduces soil fertility, suppresses beneficial microbial activity, and limits crop productivity in oil-producing agricultural areas. This study evaluated the capacity of Vetiveria zizanioides and Pani…
This study investigates the sensitivity of European call option prices to volatility under the Black-Scholes framework for deep in-the-money contracts. Using the stock quantity parameter values to compute, the results s…
We model daily price dynamics of BUA Cement and BZU Cement on the Nigerian Group Exchange (NGX) as three-state Continuous-Time Markov Chains (CTMCs) representing Low, Mid, and High regimes. Using nine months of data, es…
Hypertension remains one of the leading causes of cardiovascular morbidity and mortality worldwide, with increasing prevalence in low- and middle-income countries, including Nigeria. Nurses play a pivotal role in hypert…
This study presents a nonlinear mathematical model for investigating the impact of antimalarial drug intervention on the transmission dynamics of malaria in a coupled human–mosquito population. The total population is d…
