The residue of imidacloprid in the nectar and pollens of the plants is toxic not only to adult honeybees but also the larvae. Our understanding of the risk of imidacloprid to larvae of the honeybees is still in a very early stage. In this study, the capped-brood, pupation and eclosion rates of the honeybee larvae were recorded after treating them directly(More)
The problem of placing wireless transmitters to meet particular objectives, such as coverage and cost, has proven to be NP-hard. Furthermore, the heterogeneity of wireless networks makes the problem more intractable to deal with. This paper presents a novel multiobjective variable-length genetic algorithm to solve this problem. One does not need to(More)
OBJECTIVE To investigate the concordance between novel and conventional surveillance paradigms for ventilator-associated pneumonia (VAP). METHODS This study was conducted at a regional teaching hospital in southern Taiwan with 5 acute intensive care units. To assess the validity of novel ventilator-associated event (VAE) surveillance, we retrospectively(More)
To the Editor—We read with great interest the article by Klompas et al that described the epidemiology and attributable morbidity of ventilator-associated events (VAEs). In the study, they showed that the incidence of possible and probable ventilator-associated pneumonia (VAP) according to the new surveillance definition was 1.5 and 0.7 per 1,000(More)
