Statistical characteristics of secondary ozone density peak in the upper tropopause are analyzed from the 9-year ozonesonde measurements of density profiles at Pohang, Korea, combined with 11-year satellite measurements of the HALOE onboard the UARS.
Fig. 4. The secondary current density in the Y direction, j y2 (top), and the ratio of the secondary to primary current densities in the Y direction, j y2 /jy (bottom).
The secondary user density is ρSU.
These experiments address the issues of primary user presence, varying secondary user density, and varying total channel availability.
Addition of β-nucleation agent is interpreted as a secondary nucleation density with a coupled β-phase growth.
Distributed versions of the method are discussed and shown to outperform previously published work in a variety of simulation scenarios that study effects of primary user presence, varying secondary user density, varying total channel availability.

These hypothesis tests confirm the generally positive association between secondary structure density and the evolvability index observed in the local fit.
The evidence for a positive association between secondary structure density and the evolvability index is stronger when we analyze the subset of data consisting of helix-only proteins (fig. 4 B ).
Starting with this synthetic model, recent studies reveal that there is a strong relationship between leaf area and leaf properties such as primary and secondary vein density [ 18, 19].
