An outer membrane vesicle-associated two-track model for enterotoxigenic Bacteroides fragilis oncogenesis. [PDF]
Mol OncolEnterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

Performance-based track geometry and the track geometry interaction map
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2008 The track geometry interaction map (TGIM) is proposed as an effective way to evaluate the impact of multiple track geometry parameters on rail safety. Multi-body dynamics software has been used to simulate vehicle performance over tracks containing a large number of randomly generated lateral and vertical track geometry combinations.
