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 membership funct…
Read article →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, applicable at ordi…
Read article →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 communicative…
Read article →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 stochastic sy…
Read article →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 for estima…
Read article →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 increasin…
Read article →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, and side-cha…
Read article →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 settings. Althou…
Read article →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 responses within …
Read article →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' communication practi…
Read article →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 determinants…
Read article →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 nonlinear mathe…
Read article →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 $p_1+p_2=2n$, and the …
Read article →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 satisfies on…
Read article →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 framework f…
Read article →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' learning ou…
Read article →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 quasi-exper…
