Biological molecules are subject to random fluctuations in the rates of their synthesis, distribution, activity and decay [1] [4].
The activity administered to a patient is a measured known quantity, however the absorbed radiation dose to any point depends on the distribution, elimination and decay of the radionuclide.
We systematically varied the proportion of observations drawn from each exponential distribution and its decay parameter, τ (the average duration of an observation), in order to determine the goodness of fit of the power law function over a spectrum of parameter values.
The effects of the Reynolds number, the pipe axial distance, and the inlet swirl profiles on the swirl velocity distribution and the swirl decay are analyzed.
On the other hand, the weight distribution is heterogeneous and decays approximately as a power law, with an exponential cut-off, as shown in Figure 5, panel B. Figure 4 Network of contacts between household members aggregated over the whole study duration.
A PD transgenic model via Thy-1 promoter mediated α-synuclein over-expression exhibited several circadian phenotypes in aging: a clear reduced wheel-running activity with altered period, altered temporal distribution of sleep, and decayed spontaneous neural activity in the SCN, suggested circadian rhythm is severely disrupted in the PD model (Kudo et al., 2011).
In Schoenberg and Sayers (1995); Schubnel and Gueguen (2003), plane wave propagation was studied in elastic media weakened by open fractures; this included problems on effects of anisotropy of open crack distribution at wave propagation speeds and decay characteristics.
We report field observations of an Upper Cretaceous submarine channel levee complex within the Rosario Formation, Baja California, Mexico, which provide high-resolution data of lithofacies and ichnofacies distribution, and levee depositional thickness decay along transects perpendicular to the channel axis.
Phosphorylation of TTP by MK2 has no effect on the binding affinity of TTP for the TNF-α ARE in EMSA assays, but promotes its interaction with 14 3 3 proteins thereby altering its subcellular distribution and inhibiting its mRNA decay activity.
Differently from what has been observed previously [1], [2], [3], [13], [19], however, the FB size distributions were not compatible with (and decay faster than) a power law.
