(Cambridge University Press, 2000-12)
Over a 14-year period (1984–97) the presence of rotavirus in stool samples from children under 15 years with acute gastroenteritis was studied by enzymoimmunoanalysis. Serotyping (G1–G4) was performed using monoclonal ...

The aim of this study was to determine changes in the epidemiology of hepatitis A virus (HAV) infection in the Basque Country, Spain, and to evaluate their implications for vaccination strategies. A total of 1356 persons ...
On the Characterization of Hankel and Toeplitz Operators Describing Switched Linear Dynamic Systems with Point Delays
(Hindawi Publishing Corporation, 2009)
This paper investigates the causality properties of a class of linear time-delay systems under constant point delays which possess a finite set of distinct linear time-invariant parameterizations (or configurations) which, ...
About K-Positivity Properties of Time-Invariant Linear Systems Subject to Point Delays
(Hindawi Publishing Corporation, 2007)
This paper discusses nonnegativity and positivity concepts and related properties for the state and output trajectory solutions of dynamic linear time-invariant systems described by functional differential equations subject ...

[EN]This work will focus on some aspects of descriptive names. The New Theory of Reference,
in line with Kripke, takes descriptive names to be proper names. I will argue in this paper that
descriptive names and certain ...
Constant mean curvature hypersurfaces with constant δ-invariant
(Hindawi Publishing Corporation, 2003)
We completely classify constant mean curvature hypersurfaces (CMC) with constant
δ-invariant in the unit 4-sphere S4 and in the Euclidean 4-space E4.

The Social Economy is a new phenomenon in the Czech Republic. It means the economy with its social effects that is being supported within public politics. Some analyses have been done at J.E:purkynI University in Ústí nad ...
Geometric multiplicity margin for a submatrix
(Elsevier, 2002-07)
Let G be a square complex matrix with less than k nonconstant invariant factors. We find a complex matrix that gives an optimal approximation to G among all possible matrices that have more than or equal to k invariant ...
Resumptive pronouns and Matching effects in Zurich German Relative clauses as distributed deletion
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2005)
Zurich German (ZG) relative clauses are remarkable from a Germanic point of view in that resumptive pronouns are employed instead of relative pronouns. Reconstruction effects and Strong Crossover violations show that ...
