Full paper available upon request.
   We analyze data from men with and without HIV to assess how environmental factors contribute to aging. Our study employs causal machine-learning techniques, such as random forest and K-means clustering, to investigate the impact of air quality and weather factors on aging. The results indicate a significant impact of health on aging, with air quality and smoking having a minor effect.

   This study examines the effects of climate change and air pollution on aging, particularly in people living with HIV (PLWH). We use machine learning techniques to analyze existing data on aging rates and correlate these with historical air pollution and weather data. Our goal is to provide insights that inform climate and public health policies aimed at reducing the impact of climate change on aging in PLWH.

   This study investigates the relationship between West Nile virus (WNV) outbreaks and air quality indicators (PM₂.₅ and AQI) in California from 2016 to 2022. We employ Generalized Additive Models (GAM) and Causal Machine Learning (CML) to find a marginally significant link between PM₂.₅ levels and neuroinvasive WNV cases. Additionally, we use Poisson Event Weighted Moving Average (PEWMA) and Seasonal Autoregressive Integrated Moving Average (SARIMA) for forecasting, revealing seasonal trends in WNV outbreaks during warmer months. These findings underscore the importance of air quality in managing WNV transmission.

   This study explores the key risk factors for plastic surgery using the fuzzy forest algorithm, which is suitable for complex datasets with limited samples. We analyze NSQIP data from 2016 to 2018 and identify significant correlations in various health indicators, including renal and liver function, BMI, and anesthesia factors. Our results highlight critical factors for predicting complications and readmissions, offering valuable insights for improving risk prediction models in plastic surgery.

   This paper introduces a new tree-based machine learning algorithm to enhance the prediction of complications in plastic surgery using data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). We compare the performance of various models, including Random Forest (RF), Fuzzy Forest (FF), and a novel model called Fuzzy Forest GLM, to existing methods like the ACS-NSQIP surgical risk calculator. Our results demonstrate superior predictive accuracy of the machine learning models, particularly the Fuzzy Forest Group (FFG), in forecasting plastic surgery outcomes.
