Discovering unbounded unions of regular pattern languages from positive examples
1996
The problem of learning unions of certain pattern languages from positive examples is considered. We restrict to the regular patterns, i.e., patterns where each variable symbol can appear only once, and to the substring patterns, which is a subclass of regular patterns of the type xαy, where x and y are variables and α is a string of constant symbols. We present an algorithm that, given a set of strings, finds a good collection of patterns covering this set. The notion of a ‘good covering’ is defined as the most probable collection of patterns likely to be present in the examples, assuming a simple probabilistic model, or equivalently using the Minimum Description Length (MDL) principle.

Efficient Online Laplacian Eigenmap Computation for Dimensionality Reduction in Molecular Phylogeny via Optimisation on the Sphere
2019
Reconstructing the phylogeny of large groups of large divergent genomes remains a difficult problem to solve, whatever the methods considered. Methods based on distance matrices are blocked due to the calculation of these matrices that is impossible in practice, when Bayesian inference or maximum likelihood methods presuppose multiple alignment of the genomes, which is itself difficult to achieve if precision is required. In this paper, we propose to calculate new distances for randomly selected couples of species over iterations, and then to map the biological sequences in a space of small dimension based on the partial knowledge of this genome similarity matrix. This mapping is then used …
Modelling the inhibitory effect of copper sulfate on the growth of Penicillium expansum and Botrytis cinerea
2011
Aims: This study aimed to investigate the effect of copper sulfate (from 0 to 8 mmol kg−1) on radial growth rate and lag time of two moulds responsible for vine grapes spoilage: Penicillium expansum strain 25·03 and Botrytis cinerea, strains BC1 and BC2. Methods and results: A new model was developed to describe tailing and shoulders in the inhibition curves. Because of tailing, the minimum inhibitory concentration (MIC), was not defined as the concentration at which no growth was observed, but as the concentration at which the lag time was infinite. The concentrations at which μ = μopt/2, (Cu50), were in the range of 2·2–2·6 mmol kg−1. Radial growth rate of P. expansum and the reciprocal…
Probabilistic cross-validation estimators for Gaussian process regression
2018
Gaussian Processes (GPs) are state-of-the-art tools for regression. Inference of GP hyperparameters is typically done by maximizing the marginal log-likelihood (ML). If the data truly follows the GP model, using the ML approach is optimal and computationally efficient. Unfortunately very often this is not case and suboptimal results are obtained in terms of prediction error. Alternative procedures such as cross-validation (CV) schemes are often employed instead, but they usually incur in high computational costs. We propose a probabilistic version of CV (PCV) based on two different model pieces in order to reduce the dependence on a specific model choice. PCV presents the benefits from both…
Evaluation in Political Discourse Addressed to Women: Appraisal Analysis of Cosmopolitan's Coverage of the 2014 US Midterm Elections
2017
Abstract Before the US midterm elections of November 2014, the well-known women’s magazine Cosmopolitan decided to include politics in its contents. The editorial board stated that their aim was to encourage readers to vote and to be engaged with women’s rights advocay in the election process. To that end, Cosmopolitan created a new website, CosmoVotes, with content ranging from discussion of political issues to endorsement of specific candidates who were believed to advance women’s issues. Topics include labour rights, abortion, contraception, health, minimum wage and social equity. This paper evaluates the discourse of this new section of the Cosmopolitan website, together with readers’ r…
Fiscality of couples in fact
2019
[ES] Las parejas de hecho son una unión alternativa al matrimonio y, como tal, el ordenamiento les dedica un régimen jurídico. El presente estudio trata sobre la fiscalidad que rodea a estas uniones partiendo siempre de su situación patrimonial y los acuerdos alcanzados entre los convivientes. Se analiza el encaje dentro del IRPF de la pareja de hecho y la aplicación de las circunstancias personales y familiares a los convivientes. Asimismo, se tratará la aportación de éstos a la comunidad de bienes formada por ambos y la adquisición de bienes una vez constituida la misma. Todo ello desde la aplicación de los impuestos que gravan la transmisión o adquisición de bienes, ya sea de forma onero…
Protection of the surviving spouse in French law
2021
While French inheritance law has recently sought to give everyone more freedom to anticipate the transmission of their estate, it still guarantees to the children a reserved portion in his estate. This guarantees the deceased?s children a minimum share in his/her estate. However, the mechanisms protecting this reserve are subject to legal adjustments when spouses wish to organize the protection of the couple?s survivor, either by submitting to a conventional matrimonial regime or by giving themselves gifts that improve the legal succession of the spouse. This ensures a balance between the protection of the spouse and that of the compulsory heirs. Not seeming to be satisfied, several famous …
Principal Poincar\'e Pontryagin Function associated to some families of Morse real polynomials
2014
It is known that the Principal Poincar\'e Pontryagin Function is generically an Abelian integral. We give a sufficient condition on monodromy to ensure that it is an Abelian integral also in non generic cases. In non generic cases it is an iterated integral. Uribe [17, 18] gives in a special case a precise description of the Principal Poincar\'e Pontryagin Function, an iterated integral of length at most 2, involving logarithmic functions with only one ramification at a point at infinity. We extend this result to some non isodromic families of real Morse polynomials.
A Community in Life and Death: The Late Neolithic Megalithic Tomb at Alto de Reinoso (Burgos, Spain)
2016
The analysis of the human remains from the megalithic tomb at Alto de Reinoso represents the widest integrative study of a Neolithic collective burial in Spain. Combining archaeology, osteology, molecular genetics and stable isotope analysis (87Sr/86Sr, δ15N, δ13C) it provides a wealth of information on the minimum number of individuals, age, sex, body height, pathologies, mitochondrial DNA profiles, kinship relations, mobility, and diet. The grave was in use for approximately one hundred years around 3700 cal BC, thus dating from the Late Neolithic of the Iberian chronology. At the bottom of the collective tomb, six complete and six partial skeletons lay in anatomically correct positions. …
Resident care needs and work stressors in special care units versus non-specialized long-term care units
2006
Differences in how elderly residents' care needs affect staff's experiences of work stressors between special care units (SCUs) for dementia and psychiatric residents and non-SCUs were investigated. The data were drawn from 390 staff members in 38 long-term care SCUs, and 587 staff in 53 non-SCUs in Finland. Residents' care needs were based on the Resident Assessment Instrument (RAI) system measured by the Minimum Data Set 2.0. Work stressors (time-pressure and role-conflicts) were assessed with a staff survey questionnaire. Multiple-group regression analysis showed that residents' dependency in activities of daily living (ADL) was related to increased work stressors only in SCUs. A high pr…
