Influenza highlights the relevance of One Health, where experts in animal, human and environmental health combine to solve inter-related problems. Human disease due to pandemic (H1N1) 2009 influenza and avian and human disease due to influenza A/H5N1 are recent examples of new zoonoses with significant global impact. Management and prevention of influenza and other emerging infectious diseases ...

The one-loop effective action for a p brane embedded in a D = p+2 Minkowski spacetime in the static gauge is calculated. Rescaling the quantum fluctuation by −g0 evaluated on the background brane leads to the one-loop effective action expressed only in terms of infrared and ultraviolet divergent geometric scalars. After the infrared divergences are absorbed into the quantum fluctuation, there r...

We consider the nonlinear stability of the Kaluza-Klein monopole viewed as the static solution of the five-dimensional vacuum Einstein equations. Using both numerical and analytical methods, we give evidence that the Kaluza-Klein monopole is asymptotically stable within the cohomogeneity-two biaxial Bianchi type-IX ansatz recently introduced by Bizoń, Chmaj, and Schmidt. We also show that for s...

We study symmetry properties of quaternionic K\"ahler manifolds obtained by the HK/QK correspondence. To any Lie algebra $\mathfrak{g}$ infinitesimal automorphisms initial hyper-K\"ahler data we associate a central extension $\mathfrak{g}$, acting resulting manifold. More specifically, metrics one-loop deformation $c$-map construction, proving that projective special manifold gives rise to Kill...

We study the Lie algebra of infinitesimal isometries on compact Sasakian and K–contact manifolds. On a Sasakian manifold which is not a space form or 3– Sasakian, every Killing vector field is an infinitesimal automorphism of the Sasakian structure. For a manifold with K–contact structure, we prove that there exists a Killing vector field of constant length which is not an infinitesimal automor...
