Researchers have investigated the fluid dynamics of Helicobacter pylori (H. pylori) moving through gastric mucus using a 3D model and a magnetic field. H. pylori uses its corkscrew-like tail to move ...
Yield stress fluids (YSFs) often have a complex, nonlinear response to stress. Below the yield transition they deform in a recoverable way, like a viscoelastic solid, but above it the transition is ...
