In this paper, a cross-lingual pseudo relevance feedback (PRF) model based on weak relevant topic alignment (WRTA) is proposed for cross language query expansion on unparallel web pages. Topics in different languages are aligned on the basis of translation. Useful expansion terms are extracted from weak relevant topics according to the bilingual term similarity. Experiment results on web-derive...

In this paper, we describe our first participation in the ImageCLEF campaign. The SINAI research group participated in both the ad hoc task and the medical task. For the first task, we have used several translation schemas as well as experiments with and without pseudo relevance feedback (PRF). For the medical task, we have also submitted runs with and without PRF, and experiments using only te...

We analyze the rel leaf of the Arnoux-Yoccoz translation surface in genus 3. We show that the leaf is dense in the stratum Hp2, 2q but that the real-rel trajectory of the surface is divergent. On this real-rel trajectory, the vertical foliation of one surface is invariant under a pseudo-Anosov map (and in particular is uniquely ergodic), but the vertical foliations on all other surfaces are com...

The title compound, C10H8BrF3N2, crystallizes with two independent mol-ecules in the asymmetric unit, which can be considered as being related by a pseudo-inversion center, so their conformations are different; the corresponding N=C-N-C torsion angles are 54.6 (5) and -50.5 (5)°. In the crystal, mol-ecules related by translation in [001] inter-act through short inter-molecular Br⋯F contacts [3....

Two dependent examples are presented. 1. An example of two different convex 3D polytopes such that for each pair of their parallel facets, the facets are different, and there exists a unique translation putting one facet inside the other. 2. An example of a pointed tiling of S generated by a Laman-plus-one graph which can be regularly triangulated without adding new vertices. The paper explores...

BoolVar/pb v1.0 is an open source java library dedicated to the translation of pseudo-Boolean constraints into cnf formulae. Input constraints can be categorized with tags. Several encoding schemes are implemented in a way that each input constraint can be translated using one or several encoders, according to the related tags. The library can be easily extended by adding new encoders and / or ...

Three different algorithms, as implemented in three different computer programs, were put to the task of extracting direct space lattice parameters from four sets of synthetic images that were per design more or less periodic in two dimensions (2D). One of the test images in each set was per design free of noise and, therefore, genuinely 2D periodic so that it adhered perfectly to the constrain...
