In this paper a new MultiOBjective Evolution Strategy (MOBES) for solving multi-objective optimization problems subject to linear and nonlinear constraints is presented. MOBES is based on the new concept of C-, F-and N-tness, which allows systematically to handle constraints and (in)feasible individuals. The existence of niche infeasible individuals in(More)
In the few last years, among other tools a multiobjective evolutionary algorithm (MOBEA) for successfully solving many multicriteria optimization problems (MOPs) was proposed. However, there is a lack of the systematically testing our approach with other benchmark MOPs that may cause the algorithm very diicult to achieve its performance: robustness of the(More)
BACKGROUND Continuous outbreaks of the highly pathogenic H5N1 avian influenza A in Asia has resulted in an urgent effort to improve current diagnostics to aid containment of the virus and lower the threat of a influenza pandemic. We report here the development of a PCR-based assay that is highly specific for the H5N1 avian influenza A virus. METHODS A(More)
This paper represents a multivariable controller design methodology which is based on the solution of the multiobjective optimization problem using a multiob-jective evolution strategy with dynamical constraints boundaries. The evolution strategy allows to handle simultaneously all the types of multiple design objectives and constraints (hard and soft), and(More)
Newcastle disease virus (NDV) causes significant economic losses to the poultry industry in Southeast Asia. In the present study, 12 field isolates of NDV were recovered from dead village chickens in Vietnam between 2007 and 2012, and were characterized. All the field isolates were classified as velogenic. Based on the sequence analysis of the F variable(More)
Many post-secondary academic institutions in the United States have a First-Year Seminar Program. These seminars are designed to support the success of new incoming first-year students by combining writing, research and active discussion among small groups of students. At Dickinson College, students are required to select six seminars they find interesting(More)
Despite their classification as low pathogenicity avian influenza viruses (LPAIV), A/H9N2 viruses cause significant losses in poultry in many countries throughout Asia, the Middle East and North Africa. To date, poultry surveillance in Vietnam has focused on detection of influenza H5 viruses, and there is limited understanding of influenza H9 epidemiology(More)
BACKGROUND Influenza A viruses of swine (IAV-S) cause acute and subclinical respiratory disease. To increase our understanding of the etiology of the subclinical form and thus help prevent the persistence of IAV-S in pig populations, we conducted active virologic surveillance in Vietnam, the second-largest pig-producing country in Asia, from February 2010(More)
The complete genome sequence of a foot-and-mouth disease virus (FMDV) found in an isolate collected in northern Vietnam in 2013 appears to be closely related to a genetic cluster formed with isolates from China, Mongolia, and Russia in 2013. All of these are classified to fall within the Sea-97 lineage, for which little complete genome data are available.
