Cette communication consistait en la formulation de quelques réflexions sur le rôle de l'image dans la propagation de la dévotion à la Trinité. Elle entendait apporter quelques éléments de réponses aux questions suivantes : les traités théologiques et les textes liturgiques ont-ils suscité les expériences mystiques ou bien les visions sont-elles l'expression de la perception intime du visionnaire ? L'iconographie trinitaire a-t-elle nourri l'imagination du visionnaire ou bien est-elle, au contraire, la traduction plastique d'une expérience mystique antérieure ? [less ▲]

This paper addresses the problem of frequency control for non-synchronous AC areas connected by a multi-terminal HVDC grid. It proposes a decentralized control scheme for the DC voltages of the HVDC converters aimed to make the AC areas collectively react to power imbalances. A theoretical study shows that, by using local information only, the control scheme allows to significantly reduce the impact of a power imbalance by distributing the associated frequency deviation over all areas. A secondary frequency control strategy that can be combined with this control scheme is also proposed so as to restore the frequencies and the power exchanges to their nominal values in the aftermath of a power imbalance. Simulation results on a benchmark system with five AC areas illustrate the good performance of the control scheme. [less ▲]

A different approach is proposed for the study of satellite relative motion in an axially-symmetric gravitational field. Instead of using the Keplerian motion as the generating nominal orbit for the absolute motion, another "unperturbed" orbit is proposed instead: An equatorial orbit about an oblate planet. Based on the superintegrability of such motion, closed-form solutions for the equatorial relative motion are obtained. Analytic conditions for the periodicity of the relative motion in a generic central force field are presented, and utilized to design long-term bounded relative motion under high-order even zonal perturbations.

Objective: Autonoetic awareness enables to mentally relive personal events in memory to be aware of one’s own experiences across subjective time and so to have a feeling of individuality and self-direction. It is intimately associated with our awareness of ourselves as persons with a past and a future. Autonoetic awareness thereof contributes to construction of our identity by the recovery of past events, particularly specific events, and the imagination of future events. According to Danion’s theoretical model (2001), autonoetic awareness impairment is at the heart of schizophrenia. This deficit should depend on defective associations between separate aspects of the events during the recall and therefore, it is associated with a reduction in accessing specific information in autobiographical memory (AM). This impairment should explain identity perturbation, cognitive deficits, negative and positive symptomatology present in schizophrenia. Supporting this model, the present study evaluates the effect of a cognitive and behavioural intervention called Self-Awareness Therapy (SAT) on autonoetic awareness, AM and the capacity to imagine oneself in the future, in schizophrenia patients. Method: Fifteen patients with schizophrenia participated to SAT and, 8 patients took part in the Integrative Program Therapy (IPT) of Brenner. Before and after therapy, patients were asked to complete questionnaires to evaluate the autonoetic awareness, AM, projection into the future as well as affective and symptomatology scales. Results: For SAT, the participants reported more specific past and future events after than before the remediation therapy. Furthermore, patients reported significantly less depressive and anxiety symptoms as well as less negative symptoms after compared before the SAT. For IPT, no significant differences emerged. Discussion: These results are in line with previous study (Blairy et al., 2008) and support the notion that, in schizophrenia the retrieving of past specifics memories and projection into the future can be improved. La conscience autonoétique (CA) nous permet de revivre mentalement des évènements personnellement vécus, d’en prendre conscience à travers un temps subjectif et de ressentir un sentiment d’individualité. Elle contribue à la construction de notre identité via la récupération d’évènements passés, particulièrement les évènements spécifiques, et l’imagination d’évènements futurs. Selon le modèle de Danion (2001), une perturbation au niveau de la CA serait au cœur de la schizophrénie. Celle-ci résulterait d’un relâchement des associations entre les différents éléments d’un évènement lors du rappel et dés lors, serait associée à une réduction de l’accès aux informations spécifiques en mémoire autobiographique. Cette perturbation pourrait expliquer les troubles de l’identité, les déficits cognitifs ainsi que la symptomatologie présents dans la schizophrénie. Afin de remédier à ces déficits, nous avons élaboré une intervention cognitive et comportementale, destinée à des patients schizophrènes, qui s’appuie sur ce modèle. Cette étude présente les résultats préliminaires de la SAT en la comparant au 1er module du programme IPT. [less ▲]

A zone with significant irreversible deformations and significant changes in flow and transport properties is expected to be formed around underground excavation in the deep geological layers considered for the high level radioactive waste disposal. The present study concerns the modeling of this phenomena by a micromechanical damage model, based on a Mori-Tanaka homogenization on a cracked media. This anisotropic model is derived from Eshelby homogenized scheme, on which a coupling between damage and friction is taking into account on cracks. Compared to elastoplastic model on tunnel drilling modeling, micromechanical modeling seems very promising: both approaches provide similar EDZ sizes and shapes even if they do not have the same effects on perturbed mechanical behavior; micromechanical model also overcomes the elastoplastic one by a realistic characterization of crack processes.

Lignin is a promising molecule constituting a renewable alternative to some petrochemical industry products. Lignin is an aromatic cross-linked heteropolymer composed of three phenylpropanoids (p-hydroxyphenyl, guaiacyl and syringyl units) linked together via radical coupling reactions by specific ether or carbon-carbon bonds. With this phenylpropanoid structure, lignin is a rich resource of biobased products that could find high-valued applications in a lot of different areas like petrochemical polymer reinforcement and replacement, antioxidants, stabilizers, resins and vanillin production... The first challenge of the valorization of lignins is their extraction from raw materials. Lignins can be found in different lignocellulosic substrates like grasses, softwood and hardwood. This extraction process needs the development of suitable biomass treatments, allowing efficient lignin recuperation without degradation. This one could lead to the loss of some interesting properties and so of some valorization possibilities. In this study, beech wood (Fagus sylvatica L.) was collected in the region of Gaume (Belgium). Beech wood particles were delignified at atmospheric pressure by a mixture of formic acid/acetic acid/water. A central composite design and response surface methodology were used for the optimization of treatment parameters for delignification. The optima of two independent variables, namely time (1h30, 3h, 4h30) and temperature (87°C, 97°C, 107°C), were determined on delignification yield, pulp yield, concentration of degradation products (furfural and hydroxymethylfurfural). Moreover, the impact of these two variables on the amount of residual linkages between phenylpropanoid units was evaluated by semi-quantitative bidimensional nuclear magnetic resonance spectroscopy (NMR-HSQC). Our results highlight that the delignification yields increase when cooking time and temperature are elevated. Nevertheless, under these conditions, pulp yield decreases as hydrolysis of hemicelluloses and cellulose occurs. The hydrolysates of carbohydrates (free sugars or oligosaccharides) are contained in the black liquor. At elevated temperature and time, the amount of degradation products in the black liquor is increased. [less ▲]

In the Continuous Casting process, products are sometimes rejected or called defective due to the presence of transversal cracks. This type of macroscopic damage is expected to be due to a ductility loss during cooling in the bending and unbending areas of the CC line. In order to study this damage, a 2D model has been developed to predict at the mesoscopic level the intergranular crack event taking into account the creep and diffusion of voids. Already validated for a microalloyed steel, the model is identified and used in this study to predict the crack formation for three different grades of peritectic steels. Results show encouraging predictions of the damage. [less ▲]

La spéculation bouddhique énumère quatre types de nourriture : 1.la nourriture matérielle courante comme le riz, 2.le contact nutritif, 3.la pensée opérant comme nourriture, 4.la conscience opérant comme nourriture. Des ouvrages comme l’Abhidharmakośa de Vasubandhu (5e s.de n.è.) ou le Visuddhimagga de Buddhaghosa (même époque) spéculent à ce sujet à partir des paroles concernant la nourriture repérées dans les sermons du Buddha. La nourriture matérielle n’est pas envisagée uniquement chez les êtres humains. On spécule sur la nourriture des habitants des sphères célestes, des moines parfaits, du spermatozoide transmigratoire appelé gandharva , des vers et des damnés. Les trois autres « nourritures » méritent leur nom parce qu’elles aident la vie à se développer et à se poursuivre. C’est le cas du toucher dans le cas du couvage chez les oiseaux, sans lequel les oisillons mourraient. La pensée est (symboliquement) une nourriture dans le cas des tortues de mer qui déposent leurs œufs dans le sable , puis, au lieu de les couver, retournent dans l’océan, mais n’arrêtent pas de penser à leur future progéniture de manière à la maintenir en vie. Ajoutons que la pensée sous forme de « vouloir vivre », c'est à dire l’espérance, est un secours évident pour lutter contre un environnement hostile. La dernière nourriture, la conscience (vijñāna), est ce qui tient lieu d’âme aux yeux du bouddhisme qui n’adhère pas à la notion gréco-judéochrétienne d’âme personnelle. Le vijñāna intervient dans la vie du moine parfait qui sombre parfois dans des états d’hypnose où on le croirait mort. Pour en sortir, il a besoin de la « conscience » qui ne le quitte jamais. Le vijñāna est aussi ce qui assure la continuité d’une vie à l’autre, en garantissant une renaissance, une « reconnection » (pratisaṃdhi) avec le courant vita.l [less ▲]

The dynamic systems theory is well-established for linear systems and can rely on mature tools such as the theories of linear operators and linear integral transforms. This is why theoretical and experimental modal analysis, i.e., the computation of vibration modes from a mathematical model and from experimental data, respectively, is really quite sophisticated and advanced. Even though linear modal analysis served, and is still serving, the structural dynamics community for applications ranging from bridges to satellites, it is commonly accepted that nonlinearity is a frequent occurrence in engineering structures. Because linear modal analysis fails in the presence of nonlinear dynamical phenomena, the development of a practical nonlinear analog of modal analysis would be an extremely timely contribution; it is clearly missing in the structural dynamics literature. A new framework for nonlinear modal analysis of real-world structures, which includes the computation of nonlinear modes from finite element models, is introduced in this paper. This framework will permit a rigorous, yet understandable by the practicing engineer, analysis of nonlinear dynamical phenomena. It will also provide solid theoretical foundations for extending finite element model validation to nonlinear aerospace structures. [less ▲]

Although cellulosic biomass offers a promising alternative as an abundant renewable resource in the production of biofuels and platform chemicals, so far only a few studies have reported its aqueous-phase conversion into glucose or sugar alcohols using solid chemocatalysts. The principal reason is that these polymeric biomolecules with semi-crystalline structure cannot penetrate the pores of conventional heterogeneous chemocatalysts. New advances in the conversion of cellulose thus require the design of efficient multifunctional catalytic systems with sterically accessible acid and metal sites. [less ▲]

Piano Key Weir is a cost effective solution for rehabilitation as well as for new dam project with a high level of constraints (space, flood discharge, reservoir level).If the efficiency of the Piano Key Weir has already been well demonstrated, the definition of its optimal geometry has been still poorly approached. In order to improve the design of the complex geometry of this structure, the study of the influence of the mean geometrical parameters on the discharge capacity is an essential stage. Following a former experimental study of the flow over Piano Key Weirs, highlighting the mean influence of three geometrical parameters, this paper presents the results of an experimental parametric study. These results highlight the influence of the alveoli bottom slopes on the Piano Key Weir release capacity. Comparisons with numerical and analytical results, as well as design advices are also provided. [less ▲]

In spite of recent detections of magnetic fields in a number of β Cephei and slowly pulsating B (SPB) stars, their impact on stellar rotation, pulsations, and element diffusion is not sufficiently studied yet. One reason for this is the lack of knowledge of rotation periods, magnetic field strength distribution and temporal variability, and field geometry. New longitudinal field measurements of four β Cephei and candidate β Cephei stars, and two SPB stars were acquired with the FORS2 at the VLT. These measurements allowed us to carry out a search for rotation periods and to constrain magnetic field geometry for a few stars in our sample. [less ▲]

Exponentially growing E. coli cells contain high amounts of thiamine diphosphate (ThDP), a well-known cofactor, but only ~20% is bound to apoenzymes. We showed that the abundant free ThDP is the precursor for two triphosphorylated derivatives, thiamine triphosphate (ThTP) and the newly discovered adenosine thiamine triphosphate (AThTP). Both compounds are produced under different conditions of stress. ThTP transiently accumulates in response to amino acid starvation, but, in contrast to AThTP, its synthesis requires the presence of a carbon source yielding pyruvate. Under such conditions, the amount of cellular ThTP may reach up to 20–60% of total thiamine, while it is generally a minor compound (0.1 to 1% of total thiamine). The biological role of ThTP remains uncertain until now, though in E. coli, it seems to be required for rapid adaptation to amino acid starvation. ThTP accumulation requires inorganic phosphate and is inhibited by anoxia and cyanide. It is also blocked by low concentrations of the protonophore CCCP and is inhibited by low concentrations of DCCD, an inhibitor of FoF1-ATP synthase. These results suggest that ThTP is synthesized by a mechanism similar to oxidative phosphorylation, i. e. the reaction ThDP + Pi  ThTP catalyzed by FoF1-ATP synthase and energized by respiration. This hypothesis is supported by the finding that E. coli with FoF1-ATP synthase mutated in various subunits are unable to synthesize ThTP in minimal medium in response to glucose exposure. Moreover, a strain in which the atp operon was deleted is unable to synthesize ThTP, but transformation with a plasmid encoding the atp operon totally restores this capacity. We recently demonstrated a similar chemiosmotic mechanism for ThTP synthesis in rat brain mitochondria suggesting a conserved mechanism for ThTP synthesis between bacteria and mammals. [less ▲]

Un bilan complet met en évidence une méningite à Streptocoque Agalactiae. Une antibiothérapie empirique à base d’Ampicilline 200mg/kg/j, Céfotaxime 100mg/kg/j et Amikacine 15mg/kg/j est initiée. Ce traitement est maintenu 5 jours ; ensuite, poursuite du Céfotaxime en monothérapie pour une durée totale de 14 jours. Les complications précoces (présentes dans 62% des cas) ne sont pas mises en évidence par les différentes explorations réalisées : mesure du périmètre crânien ; échographie transfontanellaire à la recherche d’une hydrocéphalie ou d’abcès cérébraux ; électroencéphalogramme pour exclure des phénomènes paroxystiques. A moyen et long terme, une surveillance clinique, iconographique, ophtalmologique et de l’audiogramme devra être faite afin d’exclure un retard développemental, des troubles sensoriels ainsi qu’une hydrocéphalie, une encéphalomalacie, une atrophie cérébrale ou une porencéphalie. L’incidence des infections précoces à streptocoques B a pu être réduite grâce au dépistage maternel anténatal et à une antibioprophylaxie en cas de positivité du test. Cependant, l’administration perpartale systématique d’antibiotiques ne permet pas de diminuer le nombre et la gravité des infections tardives, la contamination étant, dans ces cas, essentiellement horizontale. Le taux de complications à 5 ans des méningites à SGB est estimé à 49%, ce qui justifie, chez ces enfants, un suivi neuropédiatrique et sensoriel à long terme. [less ▲]

Finding an approximation of a Nash equilibria in matrix games is an important topic that reaches beyond the strict application to matrix games. A bandit algorithm commonly used to approximate a Nash equilibrium is EXP3. However, the solution to many problems is often sparse, yet EXP3 inherently fails to exploit this property. To the knowledge of the authors, there exist only an offline truncation to tackle such issue. In this paper, we propose a variation of EXP3 to exploit the fact that solution is sparse by dynamically removing arms; the resulting algorithm empirically performs better than previous versions. We apply the resulting algorithm to a MCTS program for the Urban Rivals card game. [less ▲]

In the field of structural health monitoring or machine condition monitoring, the activation of nonlinear dynamic behavior complicates the procedure of damage or fault detection. Blind source separation (BSS) techniques are known as efficient methods for damage diagnosis. However, most of BSS techniques repose on the assumption of the linearity of the system and the need of many sensors. This article presents some possible extensions of those techniques that may improve the damage detection, e.g. Enhanced-Principal Component Analysis (EPCA), Kernel PCA (KPCA) and Blind Modal Identification (BMID). The advantages of EPCA rely on its rapidity of use and its reliability. The KPCA method, through the use of nonlinear kernel functions, allows to introduce nonlinear dependences between variables. BMID is adequate to identify and to detect damage for generally damped systems. In this paper, damage is firstly examined by Stochastic Subspace Identification (SSI); then the detection is achieved by comparing subspace features between the reference and a current state through statistics and the concept of subspace angle. Industrial data are used as illustration of the methods. [less ▲]

In this paper we formulate the tracking problem of a translating mass in a polyhedral billiard as a stabilization problem for a suitable set. Due to the discontinuous dynamics arising from nonsmooth impacts, the tracking problem is formulated within a hybrid systems framework and a Lyapunov function is given, which decreases during flow (continuous motion) and remains constant across jumps (impacts of the masses). To guarantee non-increase of the Lyapunov function at jumps, we introduce a novel concept of mirrored images of the target mass and prove that, with this concept, local tracking is achieved. Several simulations illustrate the effectiveness of the proposed approach as compared to alternative solutions. In a companion paper [6] we address global results and generalize the local approach to curved billiards. [less ▲]

Two control results are described: 1) local tracking control for convex billiards with piecewise locally Lipschitz boundary, and 2) global tracking control for special polyhedral billiards, including rectangles and equilateral triangles. The controllers are based on Lyapunov functions and a mirroring concept introduced in a companion paper. The local results require the impacts to satisfy an average dwell-time condition with parameters that depend on the Lipschitz constant of the function that characterizes the boundary. For piecewise constant boundary, and for the global results, the average dwell-time parameters are arbitrary. Tools from stability analysis for hybrid systems are used to establish the results.

Model refinements of non-linear magnetic circuits are performed via a finite element subproblem method. A com- plete problem is split into subproblems to allow a progression from 1-D to 3-D including linear to non-linear model corrections. Its solution is then expressed as the sum of the subproblem solu- tions supported by different meshes. A convenient and robust correction procedure is proposed allowing independent overlapping meshes for both source and reaction fields. It simplifies both meshing and solving processes, and quantifies the gain given by each refinement on both local fields and global quantities. [less ▲]

In this work the performance of a traditional concrete modified by the addition of nanoparticles and of a hydrophobic resin were studied. In particular, water capillary suction, water absorption at atmospheric pressure and under vacuum, chloride diffusion, sulphates resistance and carbonation rate tests were carried out. The nanocomposite concrete (hydrophobic and not hydrophobic) shows efficacy in inhibiting the water absorption and CO2 transport thanks to the internal microstructure modification induced by the nanoparticles action which makes more difficult the passage of the substances. Hydrophobic concrete, instead, very effectively avoids the water inlet, but, because of its hydrophobic character, makes the pores of concrete unsatured of water and the CO2 can diffuse faster through the concrete bulk.
