Let G be a simple graph of n vertices. We consider the problem ISil of deciding whether there exists an induced subtree with exactly i ≤ n vertices and l leaves in G. We also study the associated optimization problem, that consists in computing the maximal number of leaves, denoted by L_G(i), realized by an induced subtree with i vertices, for 2 ≤ i ≤ n. We compute the values of the map L_G for some classical families of graphs and in particular for the d-dimensional hypercubic graphs Q_d , d ≤ 6. Then we prove that the ISil problem is in general NP-complete. We also describe a nontrivial branch and bound algorithm that computes the function L_G for any simple graph G. In the special case where G is a tree, we provide a O(δn^3) time and O(n^2) space algorithm, where δ is the maximum degree of G. Finally, we exhibit a bijection between the set of discrete derivative of the sequences L_G (i) where G is caterpillar, and the set of prefix normal words. [less ▲]

Over the past decade, in vitro methods have been developed to study intestinal fermentation in pigs and its influence on the digestive physiology and health. In these methods, ingredients are fermented by a bacterial inoculum diluted in a mineral buffer solution. Generally, a reducing agent such as Na2S or cysteine-HCl generates the required anaerobic environment by releasing metabolites similar to those produced when protein is fermented, possibly inducing a dysbiosis. An experiment was conducted to study the impact of two reducing agents on results yielded by such in vitro fermentation models. Protein (soybean proteins, casein) and carbohydrate (potato starch, cellulose) ingredients were fermented in vitro by bacteria isolated from fresh feces obtained from three sows in three carbonate-based incubation media differing in reducing agent: (i) Na2S, (ii) cysteine-HCl and (iii) control with a mere saturation with CO2 and devoid of reducing agent. The gas production during fermentation was recorded over 72 h. Short chain fatty acids (SCFA) production after 24 and 72 h and microbial composition of the fermentation broth after 24 h were compared between ingredients and between reducing agents. The fermentation residues after 24 h were also evaluated in terms of cytotoxicity using Caco-2 cell monolayers. Results showed that the effect of the ingredient induced higher differences than the reducing agent. Among the latter, cysteine-HCl induced the strongest differences compared with the control, whereas Na2S was similar to the control for most parameters. For all ingredients, final gas produced per g of substrate was similar ( P>0.10) for the three reducing agents whereas the maximum rate of gas production ( Rmax) was reduced ( P<0.05) when carbohydrate ingredients were fermented with cysteine-HCl in comparison to Na2S and the control. For all ingredients, total SCFA production was similar ( P>0.10) after 24 h of fermentation with Na2S and in the control without reducing agent. Molar ratios of branched chain-fatty acids were higher ( P<0.05) for protein (36.5% and 9.7% for casein and soybean proteins, respectively) than for carbohydrate (<4%) ingredients. Only fermentation residues of casein showed a possible cytotoxic effect regardless of the reducing agent ( P<0.05). Concerning the microbial composition of the fermentation broth, most significant differences in phyla and in genera ascribable to the reducing agent were found with potato starch and casein. In conclusion, saturating the incubation media with CO2 seems sufficient to generate a suitable anaerobic environment for intestinal microbes and the use of a reducing agent can be omitted. [less ▲]

La confrontation de la version anonyme en vers de Barlaam et Josaphat avec sa mise en prose, produite au XIIIe siècle, offre un point de vue privilégié sur la langue littéraire en prose, à l’aube de son épanouissement. Parallèlement au retranchement d’épisodes entiers, le remanieur s’applique à conserver une étroite proximité avec la lettre de son modèle francien, et semble tendre vers un compromis entre fidélité au texte-source et intelligibilité du texte-cible. Ainsi, à côté de l’importation massive du matériau lexical et des structures syntaxiques du texte versifié, toutes ses interventions sont observables. Notre communication s’est focalisée sur un échantillon de neuf substitutions lexicales dont nous avons mesuré la fréquence et dont il s’agissait d’identifier les implications. En tant que témoins de l’actualisation linguistique du texte-source, ces variations (diachroniques et/ou diaphasiques) permettent d’améliorer la connaissance du vocabulaire de la mise en prose de Barlaam et Josaphat et de cerner avec plus de précision la sensibilité du remanieur à l’égard du lexique de sa source.

The purpose of this paper is to provide a comprehensive state of the art of fatigue and cyclic loading of natural rock materials. Papers published in the literature are classified and listed in order to ease bibliographical review, to gather data (sometimes contradictory) on classical experimental results and to analyse the main interpretation concepts. Their advantages and limitations are discussed, and perspectives for further work are highlighted. The first section summarises and defines the different experimental set-ups (type of loading, type of experiment) already applied to cyclic/fatigue investigation of rock materials. The papers are then listed based on these different definitions. Typical results are highlighted in next section. Fatigue/cyclic loading mainly results in accumulation of plastic deformation and/or damage cycle after cycle. A sample cyclically loaded at constant amplitude finally leads to failure even if the peak load is lower than its monotonic strength. This subcritical crack is due to a diffuse microfracturing and decohesion of the rock structure. The third section reviews and comments the concepts used to interpret the results. The fatigue limit and S–N curves are the most common concepts used to describe fatigue experiments. Results published from all papers are gathered into a single figure to highlight the tendency. Predicting the monotonic peak strength of a sample is found to be critical in order to compute accurate S–N curves. Finally, open questions are listed to provide a state of the art of grey areas in the understanding of fatigue mechanisms and challenges for the future. [less ▲]

This chapter deals with the characterization of the magnetic properties of superconductors which are subjected to magnetic fields that have been applied along two orthogonal directions, which is commonly referred to as a “crossed” magnetic field configuration. The purpose of this chapter is to describe the techniques that are useful to perform crossed field experiments, with an emphasis placed on practical aspects that are useful for designing the system and for understanding the measured data. This chapter is organized as follows. In Section 2, the key terms involved in the literature dealing with crossed field effects are defined. Section 3 deals with experimental methods and some key parameters will be outlined. In Section 4, practical conclusions will be drawn and next challenges in this area will be discussed. [less ▲]

Ce texte entend réévaluer l'idée de "pure synthèse intellectuelle" que l'on trouve chez Kant. Celle-ci cadre avec la pratique mathématique et métamathématique postérieure à Kant. Elle permet de dépasser l'alternative entre l'intuitionnisme développé dans la Critique de la raison pure et la fondation de la mathématique sur une logique formelle analytique. Je montre que cette idée convient à Bolzano et à Dedekind, dont je soutiens que les projets sont irréductibles à du logicisme et qui sont dès lors bien plus "kantiens" qu'il n'y paraît. [less ▲]

The production of cassava, the most important staple root crop in the world, is constrained by the short shelf life of the cassava storage roots that are undergoing post-harvest physiological deterioration (PPD) shortly after harvest. PPD reduces starch quality and renders the roots unpalatable and unmarketable. PPD is a complex process involving enzymatic stress responses to wounding, changes in gene expression and protein synthesis as well as accumulation of secondary metabolites. PPD can be strongly influenced by environmental factors making the identification of genotypes with delayed PPD trait difficult. In the present review, we propose an integrative presentation of PPD phenomenon based on a comprehensive analysis of several key PPD studies. We discuss recent progress in the standardization of methods to assess and score PPD tolerance in cassava roots. Traditional and improved storage techniques to extend cassava shelf-life are presented and prospects of transgenic approaches to delay PPD are discussed. [less ▲]

This article aims to identify the contributions of Steve Reich's music to sociology. His music reveals three main characteristics: it is made out of empirical material collected on the field; it is a theory of processes; it is a political and cultural act. Steve Reich's music affects sociology on these three points: it reminds the sociologist the nature of his craft and his commitment to the social world, questions his methods and practice; it even sheds light on his own concepts (in particular that of “process”). The author proposes to extract from Steve Reich’s compositional work some useful elements for the profession of sociologist. [less ▲]
