Helical and rod-shaped bacteria swim in helical trajectories with little additional propulsion from helical shape

It has frequently been hypothesized that the helical body shapes of flagellated bacteria may yield some advantage in swimming ability. In particular, the helical-shaped pathogen Helicobacter pylori is often claimed to swim like a corkscrew through its harsh gastric habitat, but there has been no direct confirmation or quantification of such claims. Using fast time-resolution and high-magnificat...

Cancellation exponents in helical and non-helical flows

Helicity is a quadratic invariant of the Euler equation in three dimensions. As the energy, when present helicity cascades to smaller scales where it dissipates. However, the role played by helicity in the energy cascade is still unclear. In non-helical flows, the velocity and the vorticity tend to align locally creating patches with opposite signs of helicity. Also in helical flows helicity ch...

Full thickness advancement flap to reconstruct large helical rim

Introduction: Auricular reconstruction of partial ear defects is usually challenging, especially in extended resections or traumas. Helical rim is the most noticeable part of ear with aesthetic significance, which demands detailed procedures. Helical rim advancement is a known procedure to reshape lacerated rim. In the original technique, a chondrocutaneous flap is raised in order to preserve t...
