Radio-frequency exposure of the yellow fever mosquito (<em>A. aegypti</em>) from 2 to 240 GHz (Publications)
In this study, the influence of far field RF exposure on A. aegypti was examined between 2 and 240 GHz. Using Finite Difference Time Domain (FDTD) simulations, the distribution of the electric field in [...] with a partial shift to higher carrier frequencies, including wavelengths of insects. This may lead to higher absorption of radio frequency (RF) electromagnetic fields (EMF) by insects and could cause [...] causing possible dielectric heating, could have an influence on behavior,...

Reactivity to accelerometer measurement of children and adolescents (Publications)
PURPOSE: Awareness of being monitored can influence participants' habitual physical activity (PA) behavior. This reactivity effect may threaten the validity of PA assessment. Reports on reactivity when [...] measurement day, and whether the day of the week and the day on which measurement started influence these differences. METHODS: Accelerometer data (Counts per minute, cpm) of children and adolescents (n = 2081) [...] pooled from eight studies in Switzerland with at least 10 hours of daily...
Impact of changes in detection effort on control of visceral leishmaniasis in the Indian subcontinent (Publications)
is not a reliable indicator of the performance of case detection programs. Duration of symptoms in detected cases can be used as an additional marker of the performance of case detection programs. [...] BACKGROUND: Control of visceral leishmaniasis (VL) on the Indian subcontinent relies on prompt detection and treatment of symptomatic cases. Detection efforts influence the observed VL incidence and how [...] Using a mathematical model for transmission and control of VL, we predict the impact of...
A community-randomised evaluation of the effect of IPTi on anti-malarial drug resistance in southern Tanzania (Publications)
Treatment in infants (IPTi) is the administration of sulphadoxine-pyrimethamine (SP) at 2, 3 and 9 months of age to prevent malaria. We investigated the influence of IPTi on drug resistance.Methods. Twenty-four [...] household surveys at baseline, then after 15 and 27 months of implementation, was tested for SP and resistance markers.Results. The frequency of SP in blood was similar in IPTi and comparison areas at baseline [...] Introduction of artemether-lumefantrine was followed by an...
Assessment of parental perception of malaria vaccine in Tanzania (Publications)
engage communities to manage the introduction of malaria vaccine in Tanzania. METHODS: In November 2011, as part of a large cross-sectional study of all 23 regions of Tanzania (mainland Tanzania and Zanzibar) [...] variables of interests were awareness and willingness to use a malaria vaccine. The main outcome measure was willingness to use a malaria vaccine. Logistic regression was used to examine the influence of predictive [...] representative sample of 5502 (out of 6210) women, aged 18 years...
Molecular approaches to diversity of populations of apicomplexan parasites (Publications)
parasites of importance either for livestock or as causative agents of human diseases. The importance of these parasites has been recognised by the European Commission and resulted in support of the COST [...] order of parasites promote multifaceted discussions and comparison of epidemiological approaches and methodological tools. This fosters mutual learning and has the potential for cross-fertilisation of ideas [...] firmly established as an integral part of field studies and intervention...
