This paper outlines work on a novel programmable braking system, which is widely applicable to most passive haptic applications and benefits from a simple design, theoretically infinite positional resolution and the ability to generate stiff collision forces, without the need for any explicit force measurements.
These results suggest that cells combine auxiliary proteins with similar ability to crosslink filaments to generate stiff cytoskeletal structures, which are required for the production of internal propulsive forces for cell migration, and that these proteins do not have redundant mechanical functions.
The wide, green gorge where the majestic Columbia River begins its final push to the sea generates so many stiff breezes that windsurfers from around the world make their way to Hood River, not far from here, to ply their colorful sails atop the churning whitecaps.
For chemically reacting flow simulations, existing splitting methods often generate nonphysical waves at stiff reaction fronts.
Here, we first used the Surface Forces Apparatus to reveal that 3T3-L1 prexposedytos exposed tumor-secretedted factors generate a stiffer Fn matrix relative to control cells.
Since the stiffeners are generally much stiffer than the panels, under external/internal/acoustic loadings, the dynamic response of the stiffened panels as a whole can contain deformations of both long- and short-wavelength, generated by the stiff and flexible components, respectively, for quite a large frequency region.
This can be achieved by simulating the surface of the object as a stiff spring that generates forces perpendicular to the surface.
Finally, stiffer clutches generated stronger contractions, suggesting that force generation and stiffness may be coupled in the embryo.
The ionic conduction offers stiff resistance to the movement of ions which generates an heating effect on the irradiation medium (Abdurahman and Olalere 2016b).
