In addition, we co-estimate the static external field B e upto n=2 in the solar magnetic reference frame and assume a time-dependent component of degree n=1 parameterized by the D st index split into its external and internal contributions (Maus and Weidelt 2004; Olsen et al. 2006); consult http://www.ngdc.noaa.gov/stp/geomag/est_ist.html for the provisional indices.
These models include a static field described by a degree 2 spherical harmonic expansion, and a time-varying field described by a dipole parameterized using the Dst index split into its external (Est) and induced (Ist) parts (Maus and Weidelt, 2004; Olsen et al., 2005).
We co-estimated the static external magnetic field up to SH degree 2 and assumed a temporally varying component of degree 1 parameterized by the Dst index split into its external Est and internal Ist counterpart (Maus and Weidelt, 2004; Olsen et al., 2005a).
Musk, 47, has a $24.6-billion fortune, according to the Bloomberg Billionaires Index, split roughly between his stakes in Tesla and SpaceX.
Three power-type fitting equations are deduced in the optimum range to quantify the relationships between separation indexes (split ratio, pressure drop and cut size) and the flowrate.
To estimate the relative importance of age and AMH, we calculated the total decrease in node impurities (measured by the Gini index) from splitting on each variable, averaged over all trees.
This difference comes from the fact that splitting a sequence into subsequences is done naturally between two successive indices, whereas splitting a distance is naturally done by splitting at an individual position.
The silicon index was split mesiodistally using sharp scalpel into two halves.
First, individual variables that form the basis for the index are split into 12 topical areas.
A total of 898 contacts were subsequently identified and linked to the index case, split into 351 primary/secondary contacts and 547 tertiary/higher-order contacts.
