A wild population of Drosophila melanogaster was subjected to selection for high and low female receptivity. Selection was only applied in females on the basis of the mating times observed in a 30-min period. We applied a selection paradigm that allowed us to conclude that females unmated after 30 min correspond to the truncated upper tail of the(More)
From a critical review of the literature on mating speed in Drosophila, the importance of fast mating in male fitness is questioned. The genetic architecture of male mating speed (MMS) has been evaluated in D. melanogaster through a populational analysis and a full 5 x 5 diallel cross between inbred lines. The results emphasize the fundamental role of the(More)
Females of Drosophila melanogaster and males of D. simulans hybridizing in a nonchoice condition were artificially selected for 12 generations. The frequency of hybridization increased from 10% to 79%. Response to selection occurred in both species, particularly in D. melanogaster. Female receptivity was the primary sexual trait that accounted for breaking(More)

In this paper, we describe the compilation and structure of two linguistic resources, a corpus and a dictionary of terms of the field of economy, developed for Galician. Together with this, we describe the use of these resources for the automatical extraction of multi-word terms by means of a combination of linguistic and statistical techniques. While doing(More)
Sentence word segmentation and Part-Of-Speech (POS) tagging are common pre-processing tasks for many Natural Language Processing (NLP) applications. This paper presents a practical application for POS tagging and segmentation disambiguation using an extension of the one-pass Viterbi algorithm called Viterbi-N. We introduce the internals of the developed(More)
Receptivity of sexually mature, virgin females, measured as the time to copulation, has been investigated. Two independent 5 x 5 diallel crosses were carried out, each one with a different male tester genotype. Interactions between male and female genotypes were detected because some lines appeared as dominant in one diallel and recessive in the other. The(More)
Direct artificial selection for a specific pattern, in the number and position of extra bristles, was carried out in a wild-type population of Drosophila melanogaster to canalize (estimated by probit width) the selected phenotypes. From the same population, independent lines were selected for extra dorsocentral bristles (lines D3 and D4) and for extra(More)
From 10 isofemale lines of D. melanogaster, the D2 line was established with the aim of obtaining an invariant phenotype at two extra dorsocentral bristles. Line D2 was also subdivided into two other lines, SA and ASD, based on their different bristle patterns. The SA line was selected for two symmetrical anterior extra bristles, and the ASD line was(More)
In this paper, we introduce a tagger environment for Galician, the native language of Galicia. Galician belongs to the group of Romance languages which developed from the Latin imposed on the northwest of the Iberian Peninsula by the Romans, with additions from the languages of peoples living here before the colonization, as well as contributions from other(More)
