The increasing shift to digital banking in Nigeria has accelerated cyber fraud losses, prompting banks to adopt proactive forensic readiness measures. Recent industry reports show that Nigerian banks lost more than N300 billion ($833 million) in a single quarter of 2023, a 534% increase year-on-year. Digital Forensic Readiness (DFR) is a proactive cybersecurity strategy that ensures digital evidence is preserved and ready for analysis before a breach occurs. This paper reviews leading forensic readiness models, including Locard’s Exchange Principle, the Diamond Intrusion Model, and the NIST Risk Management Framework, and compares their applicability to Nigerian banking. We integrate these theories into a proposed DFR framework tailored for Nigeria’s banking sector, drawing on local and global studies. Key components of DFR (such as policies, technology, people, and legal compliance) are discussed with illustrations. Current challenges, notably reactive culture, evidentiary gaps, and regulatory compliance, are highlighted. Finally, best practices and a synthesis framework are presented to guide Nigerian banks toward a more resilient forensic posture.

Intestinal helminth infections remain a major public health concern in tropical regions, with nomadic populations such as the Fulani in Adamawa State, Nigeria, facing heightened risk due to limited access to sanitation, clean water, and health education. This study assessed the prevalence and associated risk factors of intestinal helminth infections among two nomadic Fulani settlements in Hong Local Government Area (LGA). A community-based cross-sectional study was conducted from July to September 2025 in Warchirashan and Fa’a Fulani settlements. Stool samples (n = 220) were collected from randomly selected participants and analyzed using the concentration method, while socio-demographic data and risk factors for soil-transmitted helminths were obtained via structured questionnaires. Data were analyzed using SPSS v26.0, and associations between infection status and risk factors were assessed using Chi-square tests (p < 0.05). The overall prevalence of intestinal helminth infections was 34.5%, with similar rates in Warchirashan (33.6%) and Fa’a (35.5%). The most prevalent parasites were Ascaris lumbricoides (11.4%), Trichuris trichiura (12.3%), and Schistosoma mansoni (11.4%). Single-species infections predominated, although polyparasitism occurred in 33–38% of infected individuals. Age-specific prevalence was highest among 18–30-year-olds, consistent with greater occupational exposure, and infection rates were higher in males than females (39.6% vs 25.9%), although this difference was not statistically significant. Significant risk factors included source of drinking water, open/bush defecation, and inconsistent handwashing practices. The study concludes that a moderate prevalence of intestinal helminth infections persists among nomadic Fulani communities in Hong LGA, driven by environmental and behavioral determinants, and recommends integrated control strategies—combining improved sanitation, safe water access, regular deworming, and targeted health education—to reduce the infection burden across all age groups.

Nonlinear differential equations pose significant challenges for conventional analytical and numerical techniques, particularly in efficiently handling complex nonlinear terms while maintaining solution accuracy and stability. This paper presents a novel computational framework for solving such equations using the Modified Laplace–Adomian Polynomial Method (LAPM), which integrates the Laplace transform with an enhanced form of the Adomian Decomposition Method. In the proposed approach, nonlinear terms are systematically decomposed into rapidly convergent Adomian polynomials, simplifying the solution process and reducing computational complexity without compromising precision. The performance of LAPM is evaluated using several benchmark nonlinear and linear differential equations, where it exhibits superior convergence speed, accuracy, and stability when compared with traditional methods. These results demonstrate that the Modified Laplace–Adomian Polynomial Method is a reliable and efficient tool for addressing a wide class of nonlinear differential equations in applied mathematics, physics, and engineering, and contributes to the growing repertoire of semi-analytical techniques for nonlinear problem solving.

This paper, titled A Theoretical Exploration of Paraletrix Calculus as an Extension of Rhotrix Mathematics, builds upon earlier studies in generalized matrix theory by extending the structural and operational framework of non-standard matrix-like objects. Atanassov and Shannon [1] first introduced matrix-tertions and matrix-ngittrets as entities that interpolate between 2-dimensional vectors and 2×2 matrices, thereby enriching the conceptual landscape of generalized matrices. Ajibade [2] subsequently advanced the field by proposing thotrices as intermediates between 2×2 and 3×3 matrices, while further developments in rhotrix theory have established various multiplication techniques, such as heart-oriented and row–column multiplications—and yielded several important results. Recognizing the diversity of both rectangular and square matrices, the paraletrix structure was formulated as a generalization of the thotrix, allowing unequal numbers of rows and columns and thus providing a more flexible algebraic setting. This study extends the mathematical framework by introducing differentiation and integration within paraletrix calculus, defining these operations for paraletrix-valued functions with respect to an independent variable. In doing so, it lays the groundwork for a coherent calculus on paraletrices as a theoretical extension of rhotrix mathematics and generalized matrix theory.

This study examines public relations strategies adopted by the Nigeria Police Force (NPF) in managing its institutional image, with particular attention to how these strategies shape public perceptions and mitigate negative publicity. Using a descriptive survey design, questionnaires were distributed to a randomly selected sample of respondents through simple random sampling to assess the relationship between public relations practice and image management within the NPF. The findings indicate a significant positive impact of public relations strategies on improving the public image of the Nigeria Police Force, confirming that well-crafted and consistently implemented communication efforts contribute to enhanced public perception. At the same time, the study identifies persistent impediments that constrain the effectiveness of these strategies, including structural and operational challenges within the organization. The study concludes that prioritizing media relations, adopting a more strategic and evidence-informed approach to addressing the identified constraints, and conducting a comprehensive review of existing public relations strategies—grounded in open and transparent communication and stakeholder feedback—are critical for strengthening image management. These conclusions underscore the need for the Nigeria Police Force to institutionalize responsive, dialogic public relations practices as part of broader efforts to rebuild public trust.

This study presents an extended fractional-order mathematical model for blood flow through a stenosed artery under the combined effects of a magnetic field, porous medium, chemical reaction, and nanoparticle diffusion. The study aims to provide a more accurate and physiologically relevant representation of nanoparticle transport in pathological arterial flow conditions. The governing nonlinear equations for momentum and mass transfer were formulated and solved using a semi-analytical approach involving modified Bessel and Mittag–Leffler functions. Model validation through comparison with existing results showed excellent agreement, confirming the reliability of the proposed formulation. The parametric analysis revealed that increasing the chemical reaction parameter and Schmidt number reduced nanoparticle concentration, whereas a higher fractional order enhanced mass transport by weakening memory effects. The study concludes that the fractional-order framework offers an improved description of nanoparticle transport in stenosed arterial blood flow and contributes to the advancement of mathematical modeling for physiologically realistic hemodynamic analysis.

Adolescents in Nigeria are increasingly exposed to HIV/AIDS risk behaviors due to socio-economic challenges, peer influence, and limited access to sexual health education, with secondary school students in Adamawa State particularly vulnerable to early sexual debut, multiple sexual partnerships, and inconsistent condom use. This study aimed to assess the prevalence of HIV/AIDS risk behaviors among secondary school students in Adamawa State, examine the socio-demographic factors associated with these behaviors, and evaluate students’ knowledge and perceptions of HIV/AIDS transmission and prevention. A cross-sectional survey design was employed involving 300 secondary school students selected through stratified random sampling. Data were collected using a structured questionnaire covering demographic characteristics, sexual behavior, substance use, and HIV/AIDS knowledge, and were analyzed using descriptive statistics and chi-square tests. The findings showed that 30% of students experienced peer pressure to engage in sex, 28% had already had sexual intercourse, 19% reported multiple sexual partners, 18.3% admitted inconsistent condom use, 14% used substances before sex, and 12% engaged in transactional sex. Knowledge gaps were also evident, as only 70% recognized condom use as a preventive measure and 25% incorrectly believed that HIV is curable. Socio-demographic factors, including age (18–19 years), male gender, senior class level, and single-parent family structure, were significantly associated with risky sexual behavior (p < .05). These findings underscore the urgent need for comprehensive sexual education, peer mentorship programs, and improved access to sexual health resources in secondary schools. The study contributes contextual evidence on adolescent HIV vulnerability in Adamawa State and highlights the importance of addressing socio-demographic risk factors and misconceptions about HIV/AIDS to reduce risky behaviors and promote adolescent health.

Catfish production has emerged as a potentially important livelihood and food security enterprise in Taraba State; however, its productivity and sustainability remain shaped by farmer characteristics, input use, and persistent structural constraints. This study examined the economics of catfish production in Taraba State by describing the socioeconomic characteristics of fish farmers, analyzing profitability, identifying the factors influencing production output, and determining the major constraints affecting producers. Primary data were collected from 120 fish farmers across 14 local government areas using purposive sampling. The data were analyzed using descriptive statistics, gross margin analysis, and regression modeling. The findings showed that 65% of the farmers were male, 93% were below 50 years of age, 59% were married, 95% had formal education, 92% had 10 years or less of fish-farming experience, 65% belonged to cooperative societies, and 95% operated with a stocking density of 1,500 or less. Catfish farming was found to be economically viable, with a benefit–cost ratio of 1.51, although feed accounted for 54.42% of variable costs. The multiple regression model produced an R² of 0.889 and a high F-value of 823.110, significant at the 1% level, indicating strong explanatory power. Feed, labor, and water exerted positive and significant effects on output, whereas pond size had a negative and significant effect. The major constraints identified were lack of subsidies, insufficient capital, poor government support, and high feed costs. The study concludes that catfish production in Taraba State is profitable but constrained by high input costs and limited institutional support. These findings imply that targeted subsidies, improved access to credit, policy reforms to reduce production costs, infrastructure development, and farmer training are essential to enhance productivity, strengthen livelihoods, and expand the contribution of aquaculture to the state economy.

Robotic arms are widely employed in applications that require smooth motion and energy-efficient operation, particularly in tasks such as object throwing and liquid dispensing, where movement often follows a curved path toward a target point. However, conventional trajectory planning methods that rely on predefined mathematical equations may not accurately represent real-world robotic systems due to uncertainties and payload variations. This study aims to optimize the trajectory of a robotic arm moving along a parabolic path using reinforcement learning and to evaluate whether this approach can successfully learn improved trajectory patterns during motion. The research integrates initial classical physics principles for curved motion with a reinforcement learning framework to enhance trajectory following toward a desired point. The findings indicate that reinforcement learning can effectively learn optimized trajectory paths and improve the motion performance of the robotic arm. The study concludes that reinforcement learning offers a promising approach for achieving smoother robotic motion with satisfactory energy efficiency under dynamic conditions. This work contributes to the advancement of intelligent motion planning by demonstrating the potential of reinforcement learning to improve trajectory optimization in robotic systems operating under practical uncertainties.

Quadratic Riccati Differential Equations (QRDEs) are important in control theory, optimal stabilization, and nonlinear dynamics, thereby requiring numerical methods that are both accurate and computationally reliable. This study introduces a new numerical scheme (NNS) for solving QRDEs using an eighth-order power series basis function combined with interpolation and collocation techniques to approximate the exact solutions over a one-step integration interval. Through this procedure, the continuous differential equation is transformed into a system of nonlinear algebraic equations, which is then solved using the Gauss elimination method. A detailed analysis of the proposed scheme establishes its high order of accuracy, zero stability, consistency, convergence, and absolute stability, confirming its suitability for practical computation. The method was implemented on four different QRDE problems, and the results showed that the approximate solutions were in excellent agreement with the exact solutions throughout the integration interval. The study concludes that the proposed NNS is a robust, accurate, and broadly applicable approach for the numerical solution of QRDEs, offering a reliable contribution to computational methods for nonlinear differential equations.
