Plasmodium falciparum parasite prevalence in East Africa: updating data for malaria stratification Institute of Tropical Medicine
The High Burden High Impact (HBHI) strategy for malaria encourages countries to use multiple sources of available data to define the sub-national vulnerabilities to malaria risk, including parasite prevalence. Here, a modelled estimate of Plasmodium falciparum from an updated assembly of community parasite survey data in Kenya, mainland Tanzania, and Uganda is presented and used to provide a more contemporary understanding of the sub-national ...
Optical dating and archaeological survey of an inland dune along the Lower Scheldt valley at 'Warandeduinen-Speelbos' (Wetteren, East Flanders, BE) Ghent University
A sand dune at the “Warandeduinen-Speelbos” in the municipality of Wetteren (province of East Flanders, BE) has been studied within the frame of a research project about the age and formation processes of inland dunes in the Scheldt basin (NW Belgium) and their potential for Late Glacial sites. First, Optically Stimulated Luminescence (OSL) dating was applied to determine the age of dune formation and enhance the chronological framework of the ...
High-resolution 14C dating of a 25,000-year lake-sediment record from equatorial East Africa Ghent University
A high resolution optical dating study of Mostistea (South East Romania) loess palaeosol sequence using quartz Ghent University
Radiocarbon dating reveals different past managements of adjacent forest soils in the Campine region, Belgium University of Antwerp
The soils of adjacent first generation monospecific stands of Scots pine (Pinus sylvestris L.) and pedunculate oak (Quercus robur L.) in the Campine region, Belgium, apparently developed under the same forming factors, were studied for carbon dynamics to disentangle eventual different past land uses. In fact, visual observations suggested that the soil under pine experienced substantial addition of organic matter and ploughing, such to be ...
Nonlinear Least Squares Updating of the Canonical Polyadic Decomposition KU Leuven
© 2017 EURASIP. Current batch tensor methods often struggle to keep up with fast-arriving data. Even storing the full tensors that have to be decomposed can be problematic. To alleviate these limitations, tensor updating methods modify a tensor decomposition using efficient updates instead of recomputing the entire decomposition when new data becomes available. In this paper, the structure of the decomposition is exploited to achieve fast ...
Improving the intra-fraction update efficiency of a correlation model used for internal motion estimation during real-time tumor tracking for SBRT patients: Fast update or no update? University of Antwerp Vrije Universiteit Brussel KU Leuven
Background and purpose: For tumor tracking, a correlation model is used to estimate internal tumor position based on external surrogate motion. When patients experience an internal/external surrogate drift, an update of the correlation model is required to continue tumor tracking. In this study, the accuracy of the internal tumor position estimation for both the clinical available update at discrete points in time (rebuild) and an in-house ...
