On the Way AGN's Turn Off

Bacterial Pathogenesis: When a turn off is a turn on

Pathogenic bacteria express distinct sets of genes at different stages in their life cycles; inappropriate expression of normally repressed genes during host colonization can interfere with bacterial survival.

Which Way to Turn? Guide Orientation in Virtual Way Finding

In this paper we describe an experiment aimed at determining the most effective and natural orientation of a virtual guide that gives route directions in a 3D virtual environment. We hypothesized that, due to the presence of mirrored gestures, having the route provider directly face the route seeker would result in a less effective and less natural route description than having the route provid...
