Tracking the Evolution of A Coherent Magnetic Flux Rope Continuously from the Inner to the Outer Corona [PDF]
The magnetic flux rope (MFR) is believed to be the underlying magnetic structure of coronal mass ejections (CMEs). However, it remains unclear how an MFR evolves into and forms the multi-component structure of a CME.

Effects of discrete energy and helicity conservation in numerical simulations of helical turbulence
Helicity is the scalar product between velocity and vorticity and, just like energy, its integral is an in-viscid invariant of the three-dimensional incompressible Navier-Stokes equations.
