Deep learning-based delineation of whole-body organs at risk empowering adaptive radiotherapy [PDF]
BMC Medical Informatics and Decision MakingBackground Accurate delineation of organs at risk (OARs) is crucial for precision radiotherapy. Most previous autosegmentation models were only constructed for single anatomical region without evaluation of dosimetric impact.

Organizing Risk: Organization and Management Theory for the Risk Society [PDF]
Academy of Management Annals, 2020 Risk has become a crucial part of organizing, affecting a wide range of organizations in all sectors. We identify, review and integrate diverse literatures relevant to organizing risk, building on an existing framework that describes how risk is organized in three ‘modes’ – prospectively, in real-time, and retrospectively.
