Forest and agricultural land use affects the concentration and composition of dissolved organic carbon (DOC) in streams and rivers. To elucidate the impacts of forest and agricultural land use on stream DOC during storm events, we investigated DOC concentration ([DOC]), optical properties of dissolved organic matter (DOM), and ΔC-DOC in both forest- and agriculture-dominated headwater streams in South Korea in the summer of 2012. One forested and five agricultural streams were investigated.

- The study aims to create a patient-specific model to predict lung tumor motion during normal breathing, which can enhance radiation therapy for lung cancer patients.
- The researchers faced challenges with existing lung geometry models that overly smoothed surfaces and neglected important respiratory mechanics, so they developed a new method that maintains detail and accurately simulates actual breathing dynamics using a hyperelastic model for lung tissue.
- Validation of the model showed it accurately predicted tumor motion, with average position errors of less than 3 mm, indicating it is a reliable tool for respiratory motion management in radiation therapy.

Prediction of respiratory motion has the potential to substantially improve cancer radiation therapy. A nonlinear finite element (FE) model of respiratory motion during full breathing cycle has been developed based on patient specific pressure-volume relationship and 4D Computed Tomography (CT) data. For geometric modeling of lungs and ribcage we have constructed intermediate CAD surface which avoids multiple geometric smoothing procedures.
