Age-specific seriousness of avian influenza A(H7N9) in the second-wave epidemic in China

Poster Presentations 2 - Diseases at the Interface of Humans, Wildlife and Other Animals: no. 23.049PURPOSE: In spring 2013, a novel avian influenza A(H7N9) emerged in China causing more than 130 human infections mostly in the eastern provinces. The hospital fatality risk of A(H7N9) were about 35% and caused severe illness especially in older patients. In winter 2013-14, a second wave of A(H7N9) began with higher burden in the southern provinces in China. We estimated the relative risk of serious illness of patients aged 65 or above in the second wave of A(H7N9) epidemic, accounting for potential age-specific differences in poultry exposure …published_or_final_versio

Allocation of Parallel Real-Time Tasks in Distributed Multi-core Architectures supported by an FTT-SE Network

Distributed real-time systems such as automotive applications are becoming larger and more complex, thus, requiring the use of more powerful hardware and software architectures. Furthermore, those distributed applications commonly have stringent real-time constraints. This implies that such applications would gain in flexibility if they were parallelized and distributed over the system. In this paper, we consider the problem of allocating fixed-priority fork-join Parallel/Distributed real-time tasks onto distributed multi-core nodes connected through a Flexible Time Triggered Switched Ethernet network. We analyze the system requirements and present a set of formulations based on a constraint programming approach. Constraint programming allows us to express the relations between variables in the form of constraints. Our approach is guaranteed to find a feasible solution, if one exists, in contrast to other approaches based on heuristics. Furthermore, approaches based on constraint programming have shown to obtain solutions for these type of formulations in reasonable time

A Note on Graph Balancing Problems with Restrictions

We consider the graph balancing problem of providing orientations to edges in an undirected multi-graph to minimize the maximum load. We first obtain an FPTAS when the multi-graph is restricted to a tree. We also obtain some additional results for other restricted cases by showing equivalencies with related combinatorial problems.
