Osteoporosis is the most common disorder of bone metabolism. The main consequence of this disease is the increased risk of fracture. Osteoporotic fractures represent a serious problem in terms of social and economic costs. Then, there is a strong need for the assessment of the best practices in prevention and treatment of osteoporosis. Dual X-ray absorptiometry (DXA) represents the current “gol...

We would like to thank the DEXA 2002 Workshop General Chair (Professor Roland Wagner) and the organizing committee of the 13th International Conference on Database and Expert Systems Applications (DEXA 2002) for their support and their cooperation. Many thanks go to Ms. Gabriela Wagner for providing a great deal of assistance. We are very indebted to all program committee members and external r...

Faced with the increasingly serious energy and environmental crisis in the world nowadays, the development of renewable energy has attracted increasingly more attention of all countries. Solar energy as an abundant and cheap energy is one of the most promising renewable energy sources. While high-performance solar cells have been well developed in the last couple of decades, the high module cos...

This paper investigates the nutritional regulation of glycogen concentration in skeletal muscle of sheep and cattle following exercise, with particular emphasis on a comparison between these species. Four experiments are summarized, indicating a clear relationship between metabolizable energy (ME) intake and rate of muscle glycogen repletion following exercise. Sensitivity to ME intake appeared...

We derive the electromagnetic energy density in a chiral metamaterial consisting of uncoupled single-resonance helical resonators. Both the lossless and absorptive cases are studied, and the energy density is shown to be positively definite. The key relation making the derivation successful is the proportionality between the magnetization and the rate of change of the electric polarization of t...

We describe a method for automatic detection and localisation of vertebrae in clinical images that was designed to avoid making a-priori assumptions of how many vertebrae are visible. Multiple Random Forest regressors were trained to identify vertebral end-plates, providing estimates of both the location and pose of the vertebrae. The highest-weighted responses from each model were combined usi...
