Bovine fasciolosis, caused by Fasciola hepatica, is widespread in Switzerland. The risk regions were modelled in 2008 by an interactive map, showing the monthly potential risk of transmission of F. hepatica in Switzerland. As this map is based on a mathematical model, the aim of the present study was to evaluate the interactive map by means of a field survey taking different data sources into a...

BACKGROUND The objective of this study was to identify associations between the concentration of Mycobacterium avium subsp. paratuberculosis (MAP) antibodies in bulk milk and potential risk factors in herd management and herd characteristics, explaining high MAP antibody titers in milk. An extensive questionnaire was administered to 292 organic and conventional dairy farms from New York, Wiscon...

The cartogram, or value-by-area map, is a popular technique for cartographically representing social data. Such maps visually equalize a basemap prior to mapping a social variable by adjusting the size of each enumeration unit by a second, related variable. However, to scale the basemap units according to an equalizing variable, cartograms must distort the shape and/or topology of the original ...

The behavior of several landscape pattern metrics were tested against various pattern scenarios generated by neutral landscape models, including number of classes, scale-map extent, scale-resolution, class proportion, aggregation level—RULE, and aggregation level—SimMap. The results demonstrate that most of the metrics are sensitive to certain pattern scenarios, yet are not sensitive to others;...

We give the best possible upper bound on the number of exceptional values and totally ramified value number of the hyperbolic Gauss map for pseudo-algebraic Bryant surfaces and some partial results on the Osserman problem for algebraic Bryant surfaces. Moreover, we study the value distribution of the hyperbolic Gauss map for complete constant mean curvature one faces in de Sitter three-space.

1. Introduction. In the last decade, one-dimensional dynamical systems have been studied intensely from different points of view. One of the reasons for this interest is that the results about one-dimensional systems prove to be useful when studying multidimensional systems which act contractively in all but one direction. We shall call such systems near to one-dimensional. In this paper we pre...

We give a Pontryagin-Thom-Szűcs type construction for non-positive codimensional singular maps, and obtain results about cobordism and bordism groups of −1 codimensional stable maps with prescribed singular fibers.

During product design, the design office defines dimensional and geometrical parameters according to the use criteria and product functionality. The manufacturing department must integrate the manufacturing and the workpiece position dispersions during the choice of tools and the machine operating modes and parameter values to respect the functional constraints. In this article, the authors sug...

We define the notion of valuation on simplicial maps between geometric realizations of simplicial complexes in R. Valuations on simplicial maps are analogous to valuations on sets. In particular, we define the Lefschetz volumes, which are analogous to the intrinsic volumes of subsets of R. Our definition not only provides a generalization of the Lefschetz number, but also yields a Hadwigerstyle...

This paper proposes the use of cognitive schemata to model metacognitive social phenomena, characterizing the reciprocity between micro and macro dimensions in an organization. The main idea that rationalizes this research is that explicit modeling of social cognitive constructs might improve the understanding of organizational culture and learning processes. In this sense, organizational actor...
