Hamilton-Jacobi Quantization Of Continuous Systems With Higher-Order Lagrangian Density

Continuous systems with higher-order Lagrangian density are treated as first order Lagrangian density by using Hamilton-Jacobi method. An example is studied in details

Hamiltonian quantization of higher order effective lagrangian with massive vector fields

Hamilton-Jacobi approach for higher-order lagrangian density is discussed. The quantization of Yang-Mills theory with interaction term is obtained by this procedure after we converted it to the first order one

Genetic Diversity and New Lineages of Dengue Virus Serotypes 3 and 4 in Returning Travelers, Germany, 2006–2015

During 2006–2015, we analyzed 70 dengue virus (DENV) strains isolated from febrile travelers returning to Germany. High genetic diversity, including multiple co-circulating DENV lineages and emerging new lineages of DENV-3 and DENV-4, was demonstrated. Our passive surveillance system based on returning travelers yielded substantial information on DENV diversity
