Toward a rational and ethical sociotechnical system of autonomous vehicles: A novel application of multi-criteria decision analysis.

The impacts of autonomous vehicles (AV) are widely anticipated to be socially, economically, and ethically significant. A reliable assessment of the harms and benefits of their large-scale deployment requires a multi-disciplinary approach. To that end, we employed Multi-Criteria Decision Analysis to make such an assessment.

A case of posttraumatic thigh defect reconstructed using tissue expansion by elastic tube.

Reconstruction of major defects of the thigh is generally achieved by means of pedicled or free musculocutaneous flaps, and for less extensive defects, local flaps or skin grafts are currently used. In this case report we present a posttraumatic thigh defect reconstructed using tissue expansion by elastic tube. The defect was closed relatively easily without further problems, and a good result was obtained.
