On Angels and Demons. Analysis of a sequence in the iconographic programme of the encyclopedic moralization of fin´amors in Matfré Ermengaud´s Brevia…
2017
En el present treball parem esment a 3 il·luminacions del Breviari d’Amor de Matfré Ermengaut que són ben eloqüents –valga la sinestèsia: imatges que són eloqüents— de la vocació d’Ermengaut en pro de la cristianització de la fin’amors. A més, estableixen una mena de seqüència en el concert de diàleg entre història natural, història sagrada i atenció a l’amor, als amadors, a fi i efecte que estableix qui és el receptor concret de l’obra, qui el model a seguir (els àngels) i qui a defugir (el dimoni), i quin és l’àmbit d’actuació del «maligne» : la societat cortés, ecosistema de la fin’amor. This paper analyzes three illuminations of Matfré Ermengaud´s Breviari d´Amor which represent the aut…

Efficient High-Order Iterative Methods for Solving Nonlinear Systems and Their Application on Heat Conduction Problems
2017
[EN] For solving nonlinear systems of big size, such as those obtained by applying finite differences for approximating the solution of diffusion problem and heat conduction equations, three-step iterative methods with eighth-order local convergence are presented. The computational efficiency of the new methods is compared with those of some known ones, obtaining good conclusions, due to the particular structure of the iterative expression of the proposed methods. Numerical comparisons are made with the same existing methods, on standard nonlinear systems and a nonlinear one-dimensional heat conduction equation by transforming it in a nonlinear system by using finite differences. From these…
Efficient Computation of Multiscale Entropy over Short Biomedical Time Series Based on Linear State-Space Models
2017
The most common approach to assess the dynamical complexity of a time series across multiple temporal scales makes use of the multiscale entropy (MSE) and refined MSE (RMSE) measures. In spite of their popularity, MSE and RMSE lack an analytical framework allowing their calculation for known dynamic processes and cannot be reliably computed over short time series. To overcome these limitations, we propose a method to assess RMSE for autoregressive (AR) stochastic processes. The method makes use of linear state-space (SS) models to provide the multiscale parametric representation of an AR process observed at different time scales and exploits the SS parameters to quantify analytically the co…
Studying the evolution of neural activation patterns during training of feed-forward ReLU networks
2021
The ability of deep neural networks to form powerful emergent representations of complex statistical patterns in data is as remarkable as imperfectly understood. For deep ReLU networks, these are encoded in the mixed discrete–continuous structure of linear weight matrices and non-linear binary activations. Our article develops a new technique for instrumenting such networks to efficiently record activation statistics, such as information content (entropy) and similarity of patterns, in real-world training runs. We then study the evolution of activation patterns during training for networks of different architecture using different training and initialization strategies. As a result, we see …
The Effect of Smoking on Long-term Gray Matter Atrophy and Clinical Disability in Patients with Relapsing-Remitting Multiple Sclerosis
2022
Background and ObjectivesThe relationship between smoking, long-term brain atrophy, and clinical disability in patients with multiple sclerosis (MS) is unclear. Here, we assessed long-term effects of smoking by evaluating MRI and clinical outcome measures after 10 years in smoking and nonsmoking patients with relapsing-remitting MS (RRMS).MethodsWe included 85 treatment-naive patients with RRMS with recent inflammatory disease activity who participated in a 10-year follow-up visit after a multicenter clinical trial of 24 months. Smoking status was decided for each patient by 2 separate definitions: by serum cotinine levels measured regularly for the first 2 years of the follow-up (during th…
The multivariate physical activity signature associated with metabolic health in children and youth: An International Children's Accelerometry Databa…
2020
There is solid evidence for an association between physical activity and metabolic health outcomes in children and youth, but for methodological reasons most studies describe the intensity spectrum using only a few summary measures. We aimed to determine the multivariate physical activity intensity signature associated with metabolic health in a large and diverse sample of children and youth, by investigating the association pattern for the entire physical intensity spectrum. We used pooled data from 11 studies and 11,853 participants aged 5.8–18.4 years included in the International Children's Accelerometry Database. We derived 14 accelerometry-derived (ActiGraph) physical activity variabl…
Multifunctionality: Epistemic diversity and concept oriented research clusters
2008
International audience; This paper provides a mapping of the different uses of the word multifunctionality. To explore the diversity of meanings and interpretations, a comparative analysis was conducted through five national case studies in France, the Netherlands, Poland, Spain and Switzerland. The analysis conducted at national level makes it possible to identify eight Concept Oriented Research Clusters (CORCs), based on a relative homogeneity in the research practices, in the research questions addressed, in the concepts used or discussed by scientists to lead their work and in the scientific disciplines, the stream of thought or possibly the epistemic community researchers belong to. Th…
