Practical Understanding of Cancer Model Identifiability in Clinical Applications

Life, 2023
Mathematical models are a core component in the foundation of cancer theory and have been developed as clinical tools in precision medicine. Modeling studies for clinical applications often assume an individual’s characteristics can be represented as ...

Synthetic radiance simulation and evaluation for a Joint Observing System Simulation Experiment [PDF]

Journal of Geophysical Research: Atmospheres, 2012
Since 2006, a Joint Observing System Simulation Experiment (OSSE) project has been established at the United States Joint Center for Satellite Data Assimilation. The work provided here documents the simulation of synthetic satellite observations from the OSSE Nature Run (NR) and the evaluation of the simulated results.

Assessment of predictability of the Loop Current in the Gulf of Mexico from observing system experiments and observing system simulation experiments

Frontiers in Marine Science, 2023
This study presents results from numerical model experiments with a high-resolution regional forecast system to evaluate model predictability of the Loop Current (LC) system and assess the added value of different types of observations. The experiments evaluate the impact of surface versus subsurface observations as well as different combinations and ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
