In our study, VCT-based testing was preferred by women who had higher income and considered themselves to be at a low risk of HIV acquisition (no perceived concurrency and no desire for additional children).
As mentioned previously, resampling is the main obstacle to the distributed implementation of PF algorithms since all the particles have to be involved in the resampling step, i.e., it bears no natural concurrency among iterations.
We used the measure of overlapping partners in each of the prior 6 months as a concurrency proxy, where respondents were classified as either having no concurrent partners (no partners or only one partner) or any concurrent partners (two or more partners) in the month.
After partner type was added to the model, a perception of concurrency was no longer associated with condom use and, consistent with prior studies, sex with a main partner was associated with greatly decreased odds of using a condom.
Since there is no specific optimized concurrency control strategy for segment tree, our segment tree-based buffer manager suffers from concurrent updates.
Instead, for data manipulations, we can see that our B-tree-based buffer manager does not incur performance drop and still outperforms other methods under parallel processing, while the segment tree-based method suffers from high concurrency no matter which concurrency control is adopted.
In the present study, it was not possible to apply this case definition of gastroenteritis because no information was collected on concurrency of symptoms.
However, the research work on conditional HTN planning mainly concentrates on the planning domain without temporal features and pays no attention to the handling of concurrency and uncertain durations.
We find small reductions in the percentage of the population reporting more than one sexual partner and in the point prevalence of concurrency for men, but no reductions in the proportion reporting a casual sexual partner in the past year.
