OBJECTIVE Citation analysis elucidates patterns of information consumption within professional communities. The aim of this study was to analyze the citations of 87 Spanish medical journals by calculating their impact factors and immediacy indices for 2001, and to estimate the importance of Archivos de Bronconeumología within the framework of Spanish medicine. MATERIAL AND METHOD Eighty-seven...

Les auteurs font une revue de la litterature a propos de deux cas de l'agenesie de l'artere renale, anomalie rare, dont les circonstances de decouverte varient selon les cas: infections recidiventes des voies urinaires, anomalie du Perinee, hypertension arterielle.  La premiere observation concerne une fillette a.gee de 7 ans, hospitalisee pour une insuffi­sance cardiaque severe avec hypertens...

BACKGROUND Existing instruments for measuring mobility are inadequate for accurately assessing older people across the broad spectrum of abilities. Like other indices that monitor critical aspects of health such as blood pressure tests, a mobility test for all older acute medical patients provides essential health data. We have developed and validated an instrument that captures essential infor...

Query languages for object bases became enriched by generalized path expressions that allow for attribute and path variables. Optimizing queries containing generalized path expressions attracted some interest. However, many interesting queries require still a full scan over the whole object base. This unbearable situation can be remedied best by utilizing index structures. However, traditional ...

ultrasound images suffer of multiplicative noise named speckle. different de-speckling algorithms run either in spatial domain or in transformed domain. in this paper, an adaptive filter in spatial domain according to assume the nakagami distribution as the statistic of log-compressed ultrasound images is used. for de-speckling in transformed domain, the non-sub sampled shearlet transform is us...

We compute the index of the Dirac operator on spin Riemannian manifolds with conical singularities, acting from L(Σ) to Lq(Σ−) with p, q > 1. When 1 + np − n q > 0 we obtain the usual Atiyah-Patodi-Singer formula, but with a spectral cut at n+1 2 − n q instead of 0 in the definition of the eta invariant. In particular we reprove Chou’s formula for the L index. For 1+ np − n q ≤ 0 the index form...

We study the sequences of numbers corresponding to lambda terms of given sizes, where the size is this of lambda terms with de Bruijn indices in a very natural model where all the operators have size 1. For plain lambda terms, the sequence corresponds to two families of binary trees for which we exhibit bijections. We study also the distribution of normal forms, head normal forms and strongly n...

Despite λ-calculus is now three quarters of a century old, no formula counting λ-terms has been proposed yet, and the combinatorics of λ-calculus is considered a hard problem. The difficulty lies in the fact that the recursive expression of the numbers of terms of size n with at most m free variables contains the number of terms of size n− 1 with at most m + 1 variables. This leads to complex r...
