"Perhaps one of the drawbacks of the paper is that they seem to have a pretty long timescale to collapse the ice sheet," he said.
The theory and a wormlike chain model for the unfolded states allows us to obtain the persistence length lp and the fQ-dependent relaxation time, giving us an estimate of collapse timescale at the single molecular level, in the coil states of the polypeptide chain.
During a SN event, the star collapses on a dynamical timescale, for which the secular approach is not valid.
Because neutrinos rarely interact with normal matter, they can escape from the core, carrying away energy and further accelerating the collapse, which proceeds over a timescale of milliseconds.
Collapsing in the sub-microsecond timescale might allow for rapid conformational turnovers of p531-39, necessary for its efficient transactivation activity and modulation.
The process of collapse, he says, occurs on a timescale of "no more than a few decades," when the complex structures created to deal with increasing problems generated by growing complexity begin to crumble under their own weight (p. 4).
As such, the data can be empirically approximated by the exponential expression (2) where is the final total porosity and τ b is the timescale of densification which is dominantly related to the bubble collapse and relaxation timescale.
Finally, we show that a simple model for welding can accurately forecast the welding timescales of the BAF deposit at Mount Meager (as reconstructed from the collapse of the Lillooet River valley dam) using our experimental data.
The dynamical timescale is the characteristic time that it would take for a star to collapse under its own gravitational attraction without the presence of internal pressure: tau_{mathrm{dyn}} = sqrt{frac{R^{3}}{Gm}}, (1) where R and m are the radius and mass of the star.
Less certain is the timescale, with onset of rapid (> 1 mm per year of sea-level rise) collapse for the different simulations within the range of two to nine centuries.
