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…
Accurate exchange-rate forecasting is important for financial planning, international trade, investment decisions and macroeconomic management. This study develops and compares three time-series forecasting approaches f…
This study presents a stochastic SEIARV model for analysing COVID-19 transmission and vaccination intervention. The model incorporates symptomatic and asymptomatic infectious individuals, demographic recruitment and mor…
A commensurate Caputo model of HIV infection of CD4+ T cells is analysed by separating biologically admissible equilibria from algebraic roots. Building on the fractional model of Okeke et al. [1] and the hybrid activat…
The recovery of biological parameters from fractional HIV trajectories is examined alongside the mathematical properties of hybrid neural activations. Using the model of Okeke et al. [1] and the five-component activatio…
Programme accreditation by the National Universities Commission (NUC) is the main external quality assurance mechanism in Nigerian universities, but it is periodic and retrospective: weaknesses are usually discovered du…
The conjugacy decision problem is fundamental in combinatorial group theory and has applications in algebraic cryptography. Previous machine-learning studies demonstrated that conjugacy can be classified in selected non…
Missing values in rainfall datasets reduce the reliability of statistical inference and undermine decision-making in agriculture, climate studies, and environmental management. This study evaluated the performance of fi…
Let $q$ be a prime power and let $T_m(q)$ be the monoid of order-$(2m-1)$ Rhotrix arrays whose row–column multiplication corresponds to componentwise multiplication in $M_m(\mathbb F_q)\times M_{m-1}(\mathbb F_q)$. The …
A Markov model that allows a vulnerable cryptographic deployment to return to a safe state can inadvertently erase risk accumulated before remediation. We formulate a cumulative-exposure threshold model for post-quantum…
Ransomware poses an escalating threat to healthcare institutions, where attacks disrupt clinical workflows, compromise patient data, and directly endanger patient safety. Existing detection systems are reactive, binary …
This paper applies an exponential-decay geometric Brownian motion (GBM) model to illustrate how shocks and sustained downward pressure may affect Nigerian bank stock prices. The standard GBM drift is adjusted from $\mu$…
This study investigates the dynamics of Nigerian bank stock prices using an exponential-growth geometric Brownian motion framework. The model extends the classical geometric Brownian motion (GBM) by incorporating a grow…
Leadership is widely known to be the key to organizational effectiveness and firm financial performance, but the situation is complicated by the fact that leadership style, leadership behavior, employee experience, orga…
Ordinary differential equations provide a common language for representing rates of change in chemical, biological, epidemiological, and financial systems. This study develops and computationally examines four model fam…
The specification and implementation of teachers’ professional responsibilities are increasingly recognised as factors associated with student success. This study examined the relationship between the dimensions o…
Conformal mapping is one of the central geometric techniques of complex analysis because it permits a complicated planar domain to be represented by a simpler one while preserving local angles. This paper develops the a…
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 $p_1+p_2=2n$…
