Instability and "Pearling" States Produced in Tubular Membranes by Competition of Curvature and Tension
Abstract
We investigate the stability of tubular fluid membranes by perturbing them with optical tweezers. A peristaltic instability appears, with wavelength on the order of the tube circumference, characterized by tautness and suppression of curvature fluctuations in the membrane. We interpret this in terms of a model that includes a surface tension term in the elastic energy, and describes a transition to stable, finite amplitude peristaltic states. At high amplitudes the experiment reveals new dynamic states of "pearls" interconnected via thin tubes along which they travel and aggregate.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
