Air filament contraction

چکیده
We investigate numerically the contraction dynamics of a long air filament surrounded by liquid for range Ohnesorge numbers Oh. The velocity rises to maximum value Umax and then decreases due hydrodynamic drag force from medium. follows capillary-inertial scaling low Oh while it shifts capillary-viscous with increasing Our simulations reveal that contracting filaments always first rupture via end-pinching mechanism before Rayleigh–Plateau instability can develop.

Phase transition in the sliding-filament model of muscular contraction.
It was pointed out some time ago' that a first-order phase transition would be particularly suitable in the mechanism of muscular contraction at the molecular level because such a transition could provide a very large change in length from a quite small alteration in the force, or in the concentration of a molecule or ion, or in some other condition (e.g., electric field). The primary object of...
متن کاملBirth of the Sliding Filament Model of Muscular Contraction: Proposal
The offi cial date of the “birth” of the sliding fi lament theory of muscular contraction is May 22, 1954. On this day the journal Nature published two papers consecutively under the general title: “Structural Changes in Muscle During Contraction”. The fi rst paper by Andrew F. Huxley 1 and Dr. Rolf Niedergerke was entitled: “Interference microscopy of living muscle fi bres”. The second paper b...
متن کاملOn the sliding-filament model of muscular contraction, II.
This paper is a continuation of a previous article (part II).1 Our object here, and in part IV (in preparation), is to illustrate, by explicit numerical calculation, two rather different aspects of the problem under discussion. In the present article, we will consider the rate ofspontaneous fluctuation in the length of a myosin cross-bridge, assuming that it must stretch by an a -, (or helixext...
متن کاملActin turnover maintains actin filament homeostasis during cytokinetic ring contraction
Cytokinesis in many eukaryotes involves a tension-generating actomyosin-based contractile ring. Many components of actomyosin rings turn over during contraction, although the significance of this turnover has remained enigmatic. Here, using Schizosaccharomyces japonicus, we investigate the role of turnover of actin and myosin II in its contraction. Actomyosin ring components self-organize into ...
متن کاملUltrabroad Terahertz Spectrum Generation from an Air-Based Filament Plasma.
We have solved the long-standing problem of the mechanism of terahertz (THz) generation by a two-color filament in air and found that both neutrals and plasma contribute to the radiation. We reveal that the contribution from neutrals by four-wave mixing is much weaker and higher in frequency than the distinctive plasma lower-frequency contribution. The former is in the forward direction while t...
