In this paper we study the prevalence of unique entity identifiers on the Web. These are, e.g., ISBNs (for books), GTINs (for commercial products), DOIs (for documents), email addresses, and others. We show how these identifiers can be harvested systematically from Web pages, and how they can be associated with human-readable names for the entities at large scale. Starting with a simple extract...

The altitude distribution of the isotopic ratio between HD•60 and H•60 in the stratosphere is derived by retrieving the mixing ratio profiles (from 20 km to 38 km of altitude) of the two isotopic species from far-infrared emission spectra. The measurements were made with a balloon-borne Fourier Transform Spectrometer capable of 0.0025 cm -• spectral resolution during the IBEX 92 campaign. The r...

The type specimens of the bee genus Hylaeus Fabricius, 1793 described by Ferdinand Morawitz from Asia and deposited in the Zoological Museum of the Moscow State University and in the Zoological Institute, Russian Academy of Sciences St. Petersburg, are critically reviewed. Precise information with illustrations of types for 39 taxa is provided. New synonymy is established for Hylaeus incongruus...

As a follow-up of a recent study [1], we challenge the claim that the flow of interstellar helium through the solar system has changed substantially over the last decades. We argue that only the IBEX-Lo 2009/2010 measurements are discrepant with older consensus values. Then we show that the probability of the claimed variations of longitude and velocity are highly unlikely (≈1%), in view of the...

Studies on some enzymes involved in insecticide resistance in fenitrothion-resistant and susceptible strains of Musca domestica L. 2002. Prevalence of ectoparasites in a population of feral cats from north central Florida during the summer. Development of an automatic measuring system for recording the number of tail swishing against pest flies in grazing cattle. evaluation of the application o...

This paper analyses the behaviour of volatility for several international stock market indexes, namely the SP 500 (USA), the Nikkei (Japan), the PSI 20 (Portugal), the CAC 40 (France), the DAX 30 (Germany), the FTSE 100 (UK), the IBEX 35 (Spain) and the MIB 30 (Italy), in the context of non-stationarity. Our empirical results point to the evidence of the existence of integrated behaviour among ...
