1. Neuroplasticity Beyond Childhood: Evidence, Influences, & Limitations

This paper explores neuroplasticity in adults, focusing on scientific evidence that shows the adult brain can continue to change and adapt. It explains how neuroplasticity supports learning and cognitive function and may help protect against certain diseases. The paper also examines strategies to enhance neuroplasticity, while reviewing studies with negative results, thus offering a balanced perspective. In addition, the roles of social engagement and stress are discussed to show how the environment factors influence neuroplasticity. Finally, it reviews the modern advances as well as the current limitations in our understanding of the topic.

2. How Do Upcoming Digital Payment System Innovations Affect Consumer Spending and Saving Behavior, and How Does It Affect Overall Economic Growth?

By introducing tools that change saving behaviors and providing convenience that changes spending, the global transition to digital payment systems causes conflict. According to research, the "pain of paying" is lessened in digital transactions, which increases consumer spending by 40–48% and promotes impulsive purchases. On the other hand, automated digital budgeting tools successfully encourage financial resilience and savings. Macroeconomic research demonstrates that market formalization and GDP growth are positively correlated with digital adoption. According to this paper, new behaviorally-designed savings tools offer a necessary counterbalance to the convenience of payments, which drives consumption, but only if they are backed by robust financial literacy and regulatory oversight. Using case studies such as India's UPI and M-Pesa, this paper examines the relationship between payment convenience and spending, the dual impact of digital budgeting tools on saving, and the macroeconomic effects on growth. Innovations in digital payments will speed up formalities and economic activity, but their ability to serve as a strategic pillar for national development depends on how well they strike a balance between transactional convenience and instruments that encourage responsible consumer savings.

3. Empirical Atmospheric Attenuation Models for Free Space Optical Links using Nigerian Meteorological Data

Accurate prediction of atmospheric attenuation is critical for the reliable deployment of Free Space Optical (FSO) communication systems, particularly in regions with diverse climatic conditions. This paper presents a comparative validation of three widely used empirical attenuation models—Kruse, Kim, and Al Naboulsi—using real meteorological visibility data from Nigeria. Visibility records obtained from the Nigerian Meteorological Agency (NiMet) for Lagos, Port Harcourt, Abuja, Jos, and Kano were used to compute attenuation coefficients at an operating wavelength of 1550 nm. Simulation results were compared with attenuation values derived from measured visibility data using correlation and root mean square error (RMSE) metrics. Results show that the Kim model provides the highest correlation (0.93) and lowest RMSE (2.7 dB/km), demonstrating superior suitability for tropical atmospheric conditions. The findings offer validated guidelines for selecting appropriate attenuation models for FSO-based 5G backhaul and last-mile deployments in Nigeria.
