Defining Contractile And Age-Specific Remodeling In Atrial Fibrillation, Hannah Cizauskas

Dissertations

Atrial fibrillation (AFib) is the most common cardiac arrythmia worldwide and is characterized by hallmarks including electrical, fibrotic, and hemodynamic remodeling, each of which can cause or be caused by alterations in the contractile apparatus. However, there is little known about contractile remodeling in AFib. While our current understanding of AFib lacks contractile remodeling, it also largely ignores the contribution of aging-induced remodeling. Aging is the strongest risk factor for AFib development, with most patients diagnosed with AFib over the age of 70, and aging also involves the three molecular hallmarks of AFib, which could explain increased susceptibility of AFib …

Monitoring And Short-Term Forecasting Of Atmospheric Air Pollutants Using Deep Neural Networks, Prasanjit Dey

Dissertations

Accurate forecasting of near-surface atmospheric air pollutants such as PM2.5, NO2, SO2, CO, and O3 remains a critical scientific and societal challenge. This difficulty arises from several factors, including nonlinear pollutant dynamics, sparse ground monitoring net works, heterogeneous satellite observations, and strong cross-pollutant interdependencies. Substantial advances have been achieved in temporal deep learning, probabilistic modeling, satellite-based estimation, physics-informed methods, and foundation models. However, these paradigms have largely evolved in isolation. As a result, existing systems are often station-dependent or pollutant-specific and optimized for a single forecasting task. This limits their robustness and generalizability across regions and heterogeneous data regimes.
