Rising incidence, increased risk among migrants to higher risk regions, and poor prediction of individual risk have prompted a search for additional modifiable factors.
Structural optimization was performed in the high risk region of the die base, by which the stress magnitude was decreased and the load capacity was improved.
The high risk region S2 included 10% of the area with the highest incident density.
In the high risk region S2, locations with no incident happened in the previous year were still less likely to have a new incident.
For analytical purposes, the risk regions for miss detecting the PU are defined by (i) high risk region (light user); for and, (ii) medium risk region (average user); for and, (iii) low risk region (heavy user); for and. .
High Risk Region as the range of values for and, for all values of such that, Medium Risk Region as the range of values for and such that, Low Risk Region as the range of values for and such that.
high risk region (light user); for and, medium risk region (average user); for and, low risk region (heavy user); for and. Figure 2 Spectrum occupancy levels of the primary user based on the Poisson arrival process.
However our estimates of the reproductive number remain high until 24th March when the decision was taken to cull the whole high risk region.
Firstly, there is a significantly high risk region in northwest of the study area which is stable among all the 15 years.
Furthermore, active surveillance was undertaken in a High Risk Region (HRR, 5 km around the index case) and in flocks deemed dangerous contacts in a Surveillance Region (SR, 10km around index case).
