Jin et al.: Fire Smoke Elevated the Carbonaceous PM2.5 Concentration and Mortality Burden in the Contiguous U.S. and Southern Canada

Zhihao Jin June 24, 2025 0 Comments
Read Full Text: https://pubs.acs.org/doi/full/10.1021/acs.est.5c01641 Despite emerging evidence on the health impacts of fine particulate matter (PM2.5) from wildland fire smoke, the specific effects of PM2.5 composition on health outcomes remain uncertain. We developed a three-level, chemical transport model-based framework to estimate daily full-coverage concentrations of smoke-derived...

Gupta et al.: Boosting for regression transfer via importance sampling

Yang Liu PhD July 28, 2023 0 Comments
Gupta S, Bi J, Liu Y, Wildani A. 2023. Boosting for regression transfer via importance sampling. Int J Data Sci Anal. https://doi.org/10.1007/s41060-023-00414-8. Instance transfer learning methodologies are extremely efficient for continuous-valued, regression datasets. However, these methodologies can suffer negative transfer due to distribution shifts between the training and test data as well...

Bi et al.: Combining Machine Learning and Numerical Simulation for High-Resolution PM2.5 Concentration Forecast

Yang Liu PhD January 13, 2022 0 Comments
Forecasting ambient PM2.5 concentrations with spatiotemporal coverage is key to alerting decision makers of pollution episodes and preventing detrimental public exposure. In this study, we developed a PM2.5 forecast framework by combining the robust Random Forest algorithm with a publicly accessible global CTM forecast product, NASA’s Goddard Earth Observing System “Composition...

Stowell et al.: Asthma exacerbation due to climate change-induced wildfire smoke in the Western US

Yang Liu PhD January 10, 2022 0 Comments
Climate change and human activities have drastically altered the natural wildfire balance in the Western US and increased population health risks due to exposure to pollutants from fire smoke. Using dynamically downscaled climate model projections, we estimated additional asthma emergency room visits and hospitalizations due to exposure to smoke fine particulate matter (PM2.5) in the Western US...
