As a generalization of the L-fuzzy contexts, we propose the study of the L-fuzzy hypercontexts where the relation R between the objects X and the attributes Y takes as values other L-fuzzy relations. In this work, we propose the study of these structures using OWA operators in different situations. Finally, the practical case that has motivated this paper is analyzed.

INTRODUCTION Urinary iodine concentrations were analyzed in the morning urine samples of patients with differentiated thyroid cancer (DTC). MATERIAL AND METHODS The analyzed group included 572 DTC patients who were treated with radioiodine or hospitalized for evaluation of radioiodine treatment effects in 2009 at the Institute of Oncology in Gliwice. Ioduria was analyzed by PAMM (Program Agai...

We present here a view on abstraction based on the relation between sentences in a partially ordered language L and truth values of these sentences on a set of instances W . In Formal Concept Analysis, this relation is materialized as a lattice denoted as G that relates L and the powerset P(W )). We show here that projections on a lattice (here either L or the powerset P(W )) that are known to ...

The band structure of the Lamé equation, viewed as a one-dimensional Schrödinger equation with a periodic potential, is studied. At integer values of the degree parameter l, the dispersion relation is reduced to the l = 1 dispersion relation, and a previously published l = 2 dispersion relation is shown to be partially incorrect. The Hermite–Krichever Ansatz, which expresses Lamé equation solut...

The infraspecific variability of the species Leishmania infantum is studied by using genetic markers generated by random amplified polymorphic DNA (RAPD). We have applied this technique, using 18 primers of arbitrary sequence, to 33 strains of the parasite belonging to 18 zymodemes isolated in different clinical forms and hosts. Other strains belonging to the species L. donovani, L. major, L. t...

The band structure of the Lamé equation, viewed as a one-dimensional Schrödinger equation with a periodic potential, is studied. At integer values of the degree parameter l, the dispersion relation is reduced to the l = 1 dispersion relation, and a previously published l = 2 dispersion relation is shown to be partly incorrect. The Hermite–Krichever Ansatz, which expresses Lamé equation solution...

Quite a few things. In particular, reverberation mapping of NGC 4395, the lowest luminosity type 1 Active Galactic Nucleus (AGN, Lbol ∼ 10 erg/s) revealed a size of only ≃ 1 light hour for the C IV broad line region (BLR), which is by far the smallest BLR. This, together with a similar determination of a size of ∼ 200 light days in a luminous quasar (Kaspi et al. 2007), suggests that the RBLR ∝...

Technological and safety-related properties were analyzed in lactic acid bacteria isolated from Spanish dry-cured sausages in order to select them as starter cultures. In relation to technological properties, all the strains showed significative nitrate reductase activity; Lactobacillus plantarum, Lactobacillus paracasei and 52% of the Enterococcus faecium strains showed lipolytic activity and ...
