Helical Buckling in Filopodia [PDF]
Biophysical Journal, 2015 Filopodia are thin actin rich membrane protrusion that allow cells to interactively probe their environment by periodic protrusion and shrinkage interrupted by occasional kinks. Filopodial actin is thought to play a pivotal role in filopodial force transduction, bending, and rotation.

Helical buckling of Skyrme–Faddeev solitons [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Abstract Solitons in the Skyrme–Faddeev model on are shown to undergo buckling transitions as the circumference of the S1 is varied. These results support a recent conjecture that solitons in this field theory are well-described by a much simpler model of elastic rods.
