A statistical method (cross-validation) for bone loss region detection after spaceflight. [PDF]

open access: yes, 2010
Astronauts experience bone loss after the long spaceflight missions. Identifying specific regions that undergo the greatest losses (e.g. the proximal femur) could reveal information about the processes of bone loss in disuse and disease.

A combined sensitivity analysis and kriging surrogate modeling for early validation of health indicators [PDF]

open access: yes, 2014
To increase the dependability of complex systems, one solution is to assess their state of health continuously through the monitoring of variables sensitive to potential degradation modes. When computed in an operating environment, these variables, known
