We introduce GenAI4UQ, a software package for forward and inverse uncertainty quantification in model calibration, parameter estimation, and ensemble forecasting. GenAI4UQ leverages a generative AI-based conditional modeling framework to address limitations of traditional inverse modeling techniques...

Abstract Accurate short‐to‐subseasonal streamflow forecasts are becoming crucial for effective water management in an increasingly variable climate. However, streamflow forecast remains challenging over extended lead times, uncertainty in meteorological inputs, and increased frequency and variabilit...

Conclusion: Abnormal changes in thyroid hormones during pregnancy may correlate with adverse events such as pregnancy-induced hypertension and placental abruption. Clinicians should prioritize routine third-trimester monitoring of FT4, TSH, and TPO-Ab levels in twin pregnancies, particularly for wom...

Reducing ammonia (NH3) and nitrous oxide (N2O) emissions have great effects on mitigating nitrogen (N) nutrient loss and greenhouse gas emissions. Controlled release urea (CRU) can control the N release rate, which reduces reactive N loss and increases nitrogen use efficiency relative to conventiona...

Abstract Noncompartmental analysis (NCA) is a model‐independent approach for assessing pharmacokinetics (PKs). Although the existing NCA algorithms are very well‐established and widely utilized, they suffer from low accuracies in the setting of sparse PK samples. In response, we developed Deep‐NCA,...

Currently, enhancers have key transcriptional regulatory roles in muscle development. Skeletal muscle formation involves various molecules, and in animals, enhancers are one of the main types of transcriptional regulatory regions that are of great importance to regulate myogenic gene expression. In...
