BACKGROUND Recent outbreaks of avian influenza A (H5N1) in poultry throughout Asia have had major economic and health repercussions. Human infections with this virus were identified in Vietnam in January 2004. METHODS We report the clinical features and preliminary epidemiologic findings among 10 patients with confirmed cases of avian influenza A (H5N1)(More)
Exploration of an unknown environment is one of the major applications of Multi-Robot Systems. Many works have proposed multi-robot coordination algorithms to accomplish exploration missions based on multi-agent techniques. Some of these works focus on multi-robot exploration under communication constraints. In this paper, we propose an original way to(More)
In developing countries, from 80 to 90% of the people with active epilepsy do not have access to treatment. A multitude of factors such as nonavailability of antiepileptic drugs (AEDs) contributes to the treatment gap in epilepsy. Our study carried out in 2003 in southern Vietnam showed that 57% of pharmacies had AEDs. A majority of these pharmacies were(More)
The purpose of this research was to evaluate the quality of anti-epileptic drugs (AEDs) in a central city of South Vietnam. A cross-sectional study was conducted in all the outlets for AEDs. Out of 33 pharmacies 54% had AEDs. Where the drugs were available, 89% of the pharmacies, 10 units were purchased, choosing the cheapest ones. The information on the(More)
Maintaining the network connectivity in mobile Multi-Robot Systems (MRSs) is a key issue in many robotic applications. In our view, the solution to this problem consists of two main steps: (i) making robots aware of the network connectivity; and (ii), making use of this knowledge to plan robots tasks without compromising connectivity. In this paper, we view(More)
Maintaining the network connectivity during the mission of robots in Mobile MultiRobot Systems (MRSs) is a key issue in many robotics applications. In our view, the solution to this problem consists of two main steps: (i) making robots aware of the network connectivity; and (ii), making use of this knowledge in order to plan robots tasks without(More)
