Torsional Directed Walks, Entropic Elasticity, and DNA Twist Stiffness
J. David Moroz, Philip Nelson
DNA and other biopolymers differ from classical polymers due to their torsional stiffness. This property changes the statistical character of their conformations under tension from…
Self-Avoiding Walks with Writhe
J. David Moroz, Randall D. Kamien
We map self-avoiding random walks with a chemical potential for writhe to the three-dimensional complex O(N) Chern-Simons theory as N -> 0. We argue that at the Wilson-Fisher fixed…
Spontaneous Expulsion of Giant Lipid Vesicles Induced by Laser Tweezers
Roy Bar-Ziv, J. David Moroz, Elisha Moses +1
Irradiation of a giant unilamellar lipid bilayer vesicle with a focused laser spot leads to a tense pressurized state which persists indefinitely after laser shutoff. If the vesicl…
Dynamically-Stabilized Pores in Bilayer Membranes
J. David Moroz, Philip Nelson
Zhelev and Needham have recently created large, quasi-stable pores in artificial lipid bilayer vesicles [Biochim. Biophys. Acta 1147 (1993) 89]. Initially created by electroporatio…
