Abstract:

This study tests whether machine learning can forecast PM2.5 air pollution in Almaty 24 hours in advance. Three baseline methods and three ML models (Ridge, Random Forest, XGBoost) were compared on seven months of hourly sensor data. The simple 24-hour moving average outperformed every ML model — a seasonal shift between winter training data and summer test data meant the more complex models systematically overestimated. The practical takeaway: model complexity does not guarantee better forecasts.

My research examines whether giving local small-business owners a free sample of a market-research report makes them more likely to pay for a recurring service. I will compare businesses that receive a free competitive and foot-traffic report with those that receive only a direct sales pitch. The study will measure conversion rates, decision time, and owners’ reasons for accepting, declining, or delaying the offer.

Abstract:

This research paper explores how genetic, ethnic, cultural, and environmental variables intersect to influence the risk, prevalence, and progression of Alzheimer's disease (AD) globally.​It highlights notable health disparities among various ethnoracial groups (such as African Americans, Hispanics, and Asians) and evaluates lifestyle factors like diet, air pollution, and education level.Finally, the paper investigates music therapy as a non-pharmacological treatment approach, demonstrating how music stimulates multiple brain regions and engages preserved neural pathways (such as muscle and musical memory) in dementia patients.
