Type I pili are proteinaceous tethers that mediate bacterial adhesion of uropathogenic Escherichia coli to surfaces and are thought to help bacteria resist drag forces imparted by fluid flow via uncoiling of their quaternary structure. Uncoiling and recoiling have been observed in force spectroscopy experiments, but it is not clear if and how this process(More)
The free diffusion phenomena of water molecules occurs in the brain due to thermal energy, so we apply two magnetic field gradient pulses in brain tissue while it happens and we obtain a magnetic field signal associated to the statistical distribution displacement of the population of water molecules in the voxel. It allows the acquisition of a digital(More)
