An analysis of attenuation and absorption lengths of the electron number using data of the KASCADE air shower experiment is presented. The following methods are used to determine these quantities: The method of constant intensity, the attenuation of the electron number at the knee with increasing atmospheric depth, the decrease of the flux at a constant electron number with increasing zenith an...

A growing number of social scientists fear that marriage may be on the rocks and few doubt that matrimony, as we have known it, has undergone a wrenching period of change in the past several decades. Andrew Cherlin, a leading sociologist of the family, speaks of "the de-institutionalization of marriage," conceding a point to conservative commentators who have argued that marriage and the family...

BACKGROUND Biomedical scientists need to access figures to validate research facts and to formulate or to test novel research hypotheses. However, figures are difficult to comprehend without associated text (e.g., figure legend and other reference text). We are developing automated systems to extract the relevant explanatory information along with figures extracted from full text articles. Such...

Although most philosophical accounts about model/world relations focus on structural mappings such as isomorphism, similarity has long been discussed as an alternative account. Despite its attractions, proponents of the similarity view have not provided detailed accounts of what it means that a model is similar to a realworld target system. This article gives the outlines of such an account, dr...

The light signal measured by fluorescence telescopes receives strongly depending on the shower geometry with respect to the detector a non-negligible contribution from additionally produced Cherenkov light. This Cherenkov contribution has to be accounted for to determine primary parameters properly. In comparison to the previous ansatz used by other experiments, the impact of a new analytical d...

Data taken during half a year of operation of 10 LOPES antennas (LOPES-10), triggered by EAS observed with KASCADE-Grande have been analysed. We report about the analysis of correlations of radio signals measured by LOPES-10 with extensive air shower events reconstructed by KASCADE-Grande, including shower cores at large distances. The efficiency of detecting radio signals induced by air shower...

Design, setting, participants, & measurements In this longitudinal study, GFR was measured serially over approximately 4.0 years in 195 Pima Indians with type 2 diabetes. Renal function decline (RFD) was defined during this initial period by an average GFR loss $3.3%/yr, as defined previously in type 1 diabetes. Subsequently, participants were followed for up to 17.8 years to ESRD onset, death,...

Tourism specialization on the one hand may be a successful tool to achieve fast economic growth, and, on the other hand, may be detrimental for natural resources. Finding the right balance between economic benefits and environmental costs is essential to reach sustainable development, ensuring that tourist numbers do not exceed the carrying capacity of the tourism destination. In this context, ...
