The aggregate occurrence of non-vaccine types, in particular those deemed to be high-risk, is more prevalent than the vaccine specific types and our results are comparable to those of other recent UK based studies [ 15, 17].
In the presence of a power law for the probability distribution of the aggregate size, the occurrence patterns are scale-free, indicating that the patterns are invariant at different scales of observations (Convertino et al. 2012).
This rule-based engine aggregates distribution information (including occurrence status data) for a given taxon and region, recursively using its subtaxa and subregions.
(2) Stable expression in Arabidopsis by the native promoter demonstrated for the first time the occurrence of aggregates inside the ER membranes ("boluses") and vesiculation of the ER during developmental and induced senescence.
Clinical and virological influenza surveillance systems have been established in the European member states [ 1, 2], and the European Centre for Disease Prevention and Control (ECDC) aggregates data regarding influenza occurrence from these systems to enhance monitoring and reporting of disease trends across Europe [ 3].
The occurrence of aggregates with a nucleus >500 μm found at distal sites from the vent was attributed to the increase in water vapor condensation during the horizontal spreading of PDCs, causing the greater amounts of water available to accrete coarser particles (Schumacher and Schmincke 1995).
Furthermore, histological studies demonstrate that the occurrence of thrombocyte aggregates and leukostasis trigger disseminated intravasal coagulation (Yan et al. 2009).
The occurrence of small aggregates near the critical micelle concentration with radii of 2.5 nm is supported by NMR self-diffusion data.
This approach is not only tedious but is also affected by varying cell morphologies and the occurrence of cell aggregates which renders cell counting less accurate than DNA-based techniques.
The analysis of the Raman band associated with the ν1 symmetric stretching mode of ClO4 anions shows the presence of "free-ions", contact ion pairs, higher aggregates and salt segregation, whose occurrence is dependent on the salt concentration, chain lengths and cation type.
