International audienceThis work is concerned with scaling decentralized content-based publish/subscribe (CBPS) networks for Internet-wide content distribution. A fundamental step for CBPS networks to reach the Internet-scale is to move from the exhaustive filtering service model, where a subscription selects every relevant publication, to a service model capturing the quantitative and qualitative heterogeneity of information consumers' requirements. In previous work, we described a service model allowing information consumers to express the maximum number of publications they would like to receive per service period and how to take advantage of such knowledge to pace the dissemination process. This paper extends by introducing a generic service model that seamlessly supports content-based information retrieval and dissemination and investigates through extensive simulations the performances of six caching policies in terms of consumers satisfaction and bandwidth usage
EVD is a major threat to child health, especially among children under 5 years of age. To date, none of demographic and clinical features, except younger age, have been consistently shown to affect mortality outcome in children infected with Ebola virus. What is Known: • The 2014-2015 West Africa Ebola epidemic is the largest and most widespread outbreak of Ebola virus disease (EVD) in history, with more than 11,000 deaths in Guinea, Liberia, and Sierra Leone. • During ongoing outbreak investigations, it is suggested that young children aged less than 5 years are particularly vulnerable and highly susceptible to death. What is New: • Demographic and clinical characteristics of the nationwide cohort of pediatric patients with laboratory-confirmed EVD in Guinea are reported. • The results confirm the high rate of death among EVD children under 5 years of age, while none of demographic and clinical features, except younger age, could serve as a predictor of mortality outcome in pediatric patients with EVD.
Education programs must focus on picking fruits and leaves in order to make them safe and prevent injuries related to these traditional or professional activities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
