Bayesian Spatiotemporal Small-Area Estimation of HIV Testing Uptake in Ghana, 2008-2022: Integrating Machine-Learning-Derived Geospatial Covariates with District-Level BYM2-RW1 Modelling of the Ghana Demographic and Health Surveys

Background: HIV testing is the entry point into the diagnosis, treatment and viral suppression cascade, yet in many low and middle income countries the household surveys used to monitor testing coverage are not powered for estimation below the regional level. We produced calibrated district level estimates of HIV testing uptake among women in Ghana across three Demographic and Health Survey (DHS) ...

Combining Machine Learning and Directed Evolution for Optimization of a Monooxygenase

L-3,4-dihydroxyphenylalanine (L-Dopa) is an important pharmaceutical for the treatment of Parkinson's disease and a precursor to numerous catechol-containing compounds. The flavin-dependent monooxygenase HpaBC is a promising biocatalyst for microbial L-Dopa production but exhibits limited native activity toward L-tyrosine. Although structure-based machine learning (ML) models have become increasin...

Few-Shot Concept Prompt Learning for Segmentation Foundation Models via Visual Grounding
