Hurwitz loci have played a basic role in the study of themoduli space of curves at least since 1872 when Clebsch proved that Mg is irreducible by showing that a certain Hurwitz space is connected. Hurwitz cycles on Mg are essential in the work of Harris and Mumford [HM] on the Kodaira dimension of Mg and are expected to govern the length of minimal affine stratifications of Mg. Faber and Pandha...

The last fteen years have seen an explosion in work on explicit substitution, most of which is done in the style of the-calculus. In KR95a], we extended the-calculus with explicit substitutions by turning de Bruijn's meta-operators into object-operators ooering a style of explicit substitution that diiers from that of. The resulting calculus , s, remains as close as possible to the-calculus fro...

The Hamiltonian approach of the Pauli-Fierz model is studied by Derezinski and Jaksic (cf. [7]). In this paper, we give the Markovian description of this model. Using the weak coupling limit, we derive the quantum Markovian semigroup of the Pauli-Fierz system from its Hamiltonian description. Also, we give the explicit form of the associated Lindblad generator. As a consequence, we study the pr...

Data analyses and interpretation The information available as to the characteristics of the sample is limited: there are approximately 68% parents and 25% people with CF. Typically, this would be a problem, but it likely that clinical status, age, gender, country of residence etc. is of little importance as the message is generic and global. A useful variable would have been whether or not pare...

Introduction Conclusions References

Most of the traditional recommendation algorithms are based on TF-IDF, a term-based weighting method. This paper proposes a new method for recommending news items based on the weighting of the occurrences of references to concepts, which we call Concept Frequency-Inverse Document Frequency (CFIDF). In an experimental setup we apply CF-IDF to a set of newswires in which we detect 1, 167 instance...

cystic fibrosis (cf) is an inherited disease that primarily affects the lungs and the digestive system, however, it also affects a number of other organs and systems. more than 90% of mortality of  cf patients is due to lung complications.  healthy lungs are important for a long life for people with cf, we will discuss two important topics for maintaining respiratory health. chronic use of drug...
