currently available non-invasive clinical methods for diagnosing osteoporosis are mainly associated with ionizing radiation. ultrasonic assessment of bone disease is a more recent technology. a theoretical explanation for the relationship between ultrasonic parameters and bone structure is necessary. thus, two types of bone samples of perspex (hap) and perspex-glass beads were produced. each ty...

Symmetrically dividing neuroepithelial cells may produce two daughters that are both proliferating or both postmitotic, as highlighted by Zigman et al. in this issue of Neuron and Sanada and Tsai in a recent issue of Cell.

Our understanding of the nature of student ideas informs our instructional and research agendas. In this paper, I characterize student ideas in terms of five observable properties (determinacy, coherence, context-dependence, variability, and malleability) and describe how those observable properties correspond to the “misconceptions” and “pieces” models of student reasoning. I then analyze inst...
