Calibration of Tethered Particle Motion Experiments
L. Han, B. Lui, S. Blumberg +3
The Tethered Particle Motion (TPM) method has been used to observe and characterize a variety of protein-DNA interactions including DNA looping and transcription. TPM experiments e…
Hitchhiking Through the Cytoplasm
Igor M. Kulić, Philip C. Nelson
We propose an alternative mechanism for intracellular cargo transport which results from motor induced longitudinal fluctuations of cytoskeletal microtubules (MT). The longitudinal…
New Measurements of DNA Twist Elasticity
Philip Nelson
The symmetries of the DNA double helix require a new term in its linear response to stress: the coupling between twist and stretch. Recent experiments with torsionally-constrained…
Straightening of Thermal Fluctuations in Semi-Flexible Polymers by Applied Tension
Udo Seifert, Wolfgang Wintz, Philip Nelson
We investigate the propagation of a suddenly applied tension along a thermally excited semi-flexible polymer using analytical approximations, scaling arguments and numerical simula…
The Role of Bilayer Tilt Difference in Equilibrium Membrane Shapes
Udo Seifert, Julian Shillcock, Philip Nelson
Lipid bilayer membranes below their main transition have two tilt order parameters, corresponding to the two monolayers. These two tilts may be strongly coupled to membrane shape b…
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…
Front Propagation in the Pearling Instability of Tubular Vesicles
R. E. Goldstein, P. Nelson, T. Powers +1
Recently Bar-Ziv and Moses discovered a dynamical shape transformation induced in cylindrical lipid bilayer vesicles by the action of laser tweezers. We develop a hydrodynamic theo…
Dynamic Theory of Pearling Instability in Cylindrical Vesicles
Philip Nelson, Thomas Powers, Udo Seifert
We give a simple theory for recent experiments of Bar-Ziv and Moses% Phys. Rev. Lett. {\bf73} (1994) 1392, in which tubular vesicles are excited using laser tweezers to a ``perista…
Rigid Chiral Membranes
Philip Nelson, Thomas Powers
Statistical ensembles of flexible two-dimensional fluid membranes arise naturally in the description of many physical systems. Typically one encounters such systems in a regime of…
