Ex vivo thermoacoustic imaging over large fields of view with 108 MHz irradiation.

Thermoacoustic signals are generated over a large field of view by 900 ns TE10 pulses with 108 MHz carrier frequency. Test specimens selectively absorb the TE10 pulse energy producing rapid thermal expansions that generate ultrasonic pulses. 108 MHz irradiation provides excellent depth penetration in soft tissue, allowing blood and physiologic saline to generate strong signals.

Converging technologies in higher education: paradigm for the "new" liberal arts?

This article discusses the historic relationship between the practical arts (technology) and the mental (liberal) arts, suggesting that Converging Technologies is a new higher education paradigm that integrates the arts, humanities, and sciences with modern technology. It explains that the paradigm really includes all fields in higher education from philosophy to art to music to modern languages and beyond. To implement a transformation of this magnitude, it is necessary to understand the psychology of change in academia.
