Influenza virus A/Hong Kong/1774/99, isolated from a young child with mild influenza, was shown to be similar in its antigenic and genetic characteristics to H3N2 viruses circulating in pigs in Europe during the 1990s and in particular to be closely related to viruses isolated from two children in the Netherlands in 1993. Similar viruses had previously not been identified outside Europe. Althou...

In the current study of robust stability of infinite-dimensional systems, internal exponential stability is not necessarily guaranteed. This paper introduces a new class of impulse responses called R, in which the usual notion of L2-input/output stability guarantees not only external but also internal exponential stability. The result is applied to derive a closed-loop stability condition, and ...

Two decades after the first record of invasive mussel Corbicula fluminea (Müller, 1774) in Bulgaria 2001, it has been found many surface lotic and standing waters Bulgarian Danube River Basin.

We mainly investigate the global behavior to the family of higher-order nonautonomous recursive equations given by yn p ryn−s / q φn yn−1, yn−2, . . . , yn−m yn−s , n ∈ N0, with p ≥ 0, r, q > 0, s,m ∈ N and positive initial values, and present some sufficient conditions for the parameters andmaps φn : R m → R , n ∈ N0, under which every positive solution to the equation converges to zero or a u...

BOSTON – Coinfections with both respiratory syncytial virus and rhinovirus were common and associated with increased length of stay in a prospective multicenter study of more than 2,000 children under 2 years of age who were hospitalized with bronchiolitis. The clinical value of testing for an infectious etiology in a child with bronchiolitis is unclear. Indeed, the recommendation is not to tes...

Augustin Fresnel, who was born in Broglie (Eure, northern France) in 1788 and died in Ville-d’Avray (currently in the Hauts-de-Seine department) in 1827, began his education at the Ecole polytechnique in Paris at the age of 16. Five years later, he became a member of the Corps des ponts et chaussées [Corps of Bridges]. Unanimously elected as a member of the Academy of Sciences in 1823, he accom...
