This assumption leads to the design of a model with a truncated integration interval which requires storage of and integration over a much shorter period of the particle's history compared to other history force models.
Since α particles, by comparison with β particles, have a much shorter path length as well as a much higher LET, they are significantly more selective and potent in killing targeted cells (McDevitt and Scheinberg, 2002).
If the drifting timescale of dust particles due to the P-R drag tPR is much shorter than the timescale of their mutual, destructive collisions tcol, the particles can get out of the dust source region by the P-R drag.
The temporal lifetimes of the LIF signals are found to be much longer than that expected for molecules at the same temperature, yet much shorter and spectrally different than that of soot particles.
On the other hand, consistent with the much shorter range of Auger electrons compared with α-particles, the cytotoxicity of 125I]SGMIB-MNT was much more specific with a 60- to >3,500-fold >3,500-foldtoxicity thigherat seen for nonspecytotoxicityodoBSA, compared withan specificithatactor of about 7 for the α-emitter.
Our results show that the time scale proposed for a dust particle to leave the ring is much shorter than predicted before even in the presence of a coorbital moonlet.
On the other side, UHE neutrinos, like the extragalactic component, may only cross much shorter distances and thus can be used to probe superficial structures (Earth-skimming particles).
For a much shorter pulse length, τ = 1 ms, the general trend of size distribution is the same, but particles are much smaller and the uniform size distribution lasts to longer immersion times.
This is much shorter as compared to 24 h that are in general required for CDV to produce free viral particles that can subsequently re-infect a new cell [ 12].
(The \ \ce{K1^0}\) meson has a much shorter lifetime than the \ \ce{K2^0}\) meson, so that if we start with a beam containing both types of particles, after a time only the \ \ce{K2^0}\) mesons will remain).
