Fibronectin fiber creep under constant force loading

Stability of adhesion clusters under constant force.

We solve the stochastic equations for a cluster of parallel bonds with shared constant loading, rebinding, and the completely dissociated state as an absorbing boundary. In the small force regime, cluster lifetime grows only logarithmically with bond number for weak rebinding, but exponentially for strong rebinding. Therefore rebinding is essential to ensure physiological lifetimes. The number ...

Creep Analysis of Bamboo High-Density Polyethylene Composites: Effect of Interfacial Treatment and Fiber Loading Level

The effect of chemical treatment at fiber–plastic interface and fiber loading level on creep property of bamboo fiber high-density polyethylene (BF/HDPE) composites was investigated. For single modifier systems, the use of maleic anhydride grafted polyethylene (PE-g-MA) as a coupling agent helped reduce the creep and achieved the optimum effect at the 5.7% loading level. The addition of either ...

Investigation of the Fiber/Matrix Interphase Under High Loading Rates

DNA unzipped under a constant force exhibits multiple metastable intermediates.

Single molecule studies, at constant force, of the separation of double-stranded DNA into two separated single strands may provide information relevant to the dynamics of DNA replication. At constant applied force, theory predicts that the unzipped length as a function of time is characterized by jumps during which the strands separate rapidly, followed by long pauses where the number of separa...

Two - sided Bounds for Ruin Probability under Constant Interest Force

In this paper we investigate the ruin probability in the classical risk model under a positive constant interest force. We restrict ourselves to the case where the claim size is heavy-tailed, i.e. the equilibrium distribution function (e.d.f.) of the claim size belongs to a wide subclass (denoted A) of subexponential distributions. Two-sided estimates for the ruin probability are developed by r...
