Xenobiotic resistance in animals, plants, yeast, and bacteria is known to involve ATP binding cassette transporters that efflux invading toxins. We present data from yeast and a higher plant indicating that xenobiotic resistance also involves extracellular ATP degradation. Transgenic upregulation of ecto-ATPase alone confers resistance to organisms that(More)
Herbicide resistance is an important trait often introduced into crop plants. Mechanisms of resistance can involve a mutant target protein that is unaffected by the herbicide, or metabolic detoxification or degradation of the herbicide. Recently, we showed that overexpression in Arabidopsis thaliana of either psNTP9, the garden pea apyrase gene, or AtPgp1,(More)
Using the art of puppetry to create new and fascinating content is the basis of this paper. When puppetry combined with motion capture, one can create interesting work that is both easy to perform and has a unique sense of motion. There are several reasons to use this approach instead of traditional computer animation or motion capture such as spontaneous(More)
Typically motion capture data is used to drive characters. To accomplish this, the actor has to mimic the body shape of the targeted character via posture or using props. The actor also has to move with a predetermined style. A skeletal system is then applied to the point marker data, in order to attach movement to the model. This whole process is oriented(More)
Role-playing is an essential component to social skills training in early childhood education. However, current programs are either not interactive enough in role-playing, or through the process of interaction with adults, become confrontational and frightening. A combination of virtual reality and performance animation can provide an environment for a(More)
