Bond behavior during rolling. (A) Slip-bond lifetimes (triangles) go down as bond force (diamonds) ramps up with increasing shear. (B) As shear increases, the average height between the surface and the bottom of the cell goes down (triangles), allowing the average number of fimbriae touching the surface (diamonds) and the average number of bonds (squares) to go up. Error bars are mean ± SE.
