Image de la menace par excellence, le Grand Méchant Loup est un adversaire dont on ne compte plus les apparitions, notamment dans les fictions destinées au jeune public. Dans Les Trois Petits Cochons, qui s’impose comme cas d’école parmi ces récits où surgit l’animal redouté, le loup devient l’ennemi du cochon, une créature traditionnellement associée à l’enfance. Ce tandem, qui repose sur un principe général d’opposition, brasse avec lui une série de représentations qui transparaissent en filigrane. Le détour opéré par l’histoire culturelle du cochon et quelques-uns de ses prolongements cinématographiques permet de dessiner progressivement les contours de la place occupée par le loup dans ce conte.

The strength of respiratory muscles is crucial for quality of life, especially for patients with lung or neurological disorders. Several methods can be used to assess them: i.e direct or indirect, voluntary or involuntary. The conventional spirometry method assesses indirectly the respiratory function by measuring maximum inspiratory and expiratory pressure, which reflects the coordination of all respiratory muscles. Techniques of magnetic and electrical stimulation can detect a specific muscle dysfunction, independently of the patient's motivation, however they are invasive methods as measurements are made in the esophagus and stomach. The voluntary techniques are generally non-invasive and require patient's cooperation. Measures of respiratory muscle strength, coupled to a conventional spirometry, can predict the development of ventilatory support in patients at risk, and may be useful during weaning from mechanical ventilation in intensive care units.

Of all the royal families of ancient or modern fame, few are as iconic as the eighteenth dynasty of pharaohs of the New Kingdom of Egypt, whose opulence and deeds we are still familiar to nearly 3,500 years after their time. Tenth pharaoh of this dynasty and father of Tutankhamun, Akhenaten (Amenhotep/Amenhotep IV) still fascinates Egyptologists and history lovers through the many questions surrounding his atypical rule. One of the most striking aspects of the so-called Amarna period concerns the representations of the pharaoh himself, very confusing compared to the traditional iconography of the New Kingdom. These intriguing portraits of Pharaoh raised a whole lot of medical assumptions, more or less substantiated. We review here the main theories developed throughout history. [less ▲]

Recent events such as natural catastrophes or terrorism attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional events. For more than 10 years, the University of Liege is strongly involved in researches investigating the response of structures further to such exceptional events ([1] and [2]). The present paper gives a global overview on recent or ongoing developments performed at the University of Liege in the field of robustness of steel building structures subjected to impact loading leading to the loss of a column. The conducted studies are founded on a combination of experimental, numerical and analytical approaches with the final aim to propose simplified procedures useful for practitioners and allowing ensuring an appropriate level of robustness to structures for the considered scenario [less ▲]

Au fil des siècles, le corpus latin des vitae sanctorum et des passiones martyrum s’est enrichi par l’introduction de nouveaux textes, par la réécriture et l’adaptation d’anciens remis au goût du jour, ainsi que par la traduction d’oeuvres issues du monde byzantin. Le phénomène de la réécriture hagiographique est bien connu et a fait l’objet de nombreux travaux. Celui de la traduction dans ce domaine reste en revanche peu exploité, tant il existe d’obstacles à son étude (absence de répertoire, manque d’éditions critiques, difficultés à identifier les traductions et les modèles grecs, etc.). Le présent travail propose une approche originale du phénomène, basée sur l’utilisation de la statistique linguistique. Cette approche consiste à étudier le latin utilisé par les traducteurs hagiographes pour rendre leur modèle grec et les techniques qu’ils ont adoptées pour le traduire en considérant les traductions non pas une à une, mais d’une manière comparative au moyen de l’analyse quantitative, dans le but de caractériser et de classer les traductions sur base de critères linguistiques, d’identifier et de qualifier des pratiques, des traditions localisées, des spécificités d’école ou de traducteur. La pratique de la traduction est examinée à travers un corpus de 35 textes représentatif des différentes phases de l’histoire de la traduction hagiographique latine au Moyen Âge et des différents foyers de traduction en Italie. Les analyses sont menées sur divers paramètres lexicaux et syntaxiques, en comparant d’abord le corpus, pris dans son ensemble, à un corpus de textes non traduits, puis en comparant entre eux les différents sous-corpus de traductions. Le premier type de comparaison (externe) a pour objectif de mettre en évidence les caractéristiques des traductions en général, le second (interne) de dégager les spécificités de chaque groupe de traductions.

This paper presents the modelling of the performance of small propellers used for Vertical Take Off and Landing Micro Aerial Vehicles (VTOL MAVs) operating at low Reynolds numbers and in oblique flow. Blade Element Momentum Theory (BEMT), Vortex Lattice Method (VLM) and momentum theory for oblique flow are used to predict propeller performance. For validation, the predictions for a commonly used propeller for VTOL MAVs are compared to a set of wind tunnel experiments. Both BEMT and VLM succeed in predicting correct trends of the forces and moments acting upon the propeller shaft, although accuracy decreases significantly in oblique flow. For the dataset analysed here, combining the available data of the propeller in purely axial flow with momentum theory for oblique flow and applying a correction factor for the wake skew angle results in more accurate performance estimates at all elevation angles.

Scientists in many fields of research have developed models, theories and concepts attempting to grasp and manage dangers that are often difficult to imagine. Among the different perspectives, the Science and Technology Studies (STS) Vulnerability Approach seems very promising. Relying on a constructivist paradigm, it is based on an inductive collection and analysis of a wide range of factors, with a particular focus on cultural factors and actual day-to-day practices. In this paper, we present the roots of this approach and we display findings based on three case studies exploring emergency planning in three different contexts (a city near a SEVESO plant, a school near a nuclear plant, and a city confronted to multiple catastrophic scenarios). The cases studies were realized by conducting three Focus Groups with different types of stakeholders (citizens, teachers, firemen, decision makers, etc.). After presenting the results of the case studies, we discuss how stakeholders’ participation can inform such type of vulnerability analysis in the context of emergency planning. We argue that participation fosters a deep understanding of actual safety governance practices which allows innovative results to emerge as well as it initiates a learning process among the participants. It contributes to questioning the relations between decision-makers, experts and citizens. It has the potential of bypassing the positivist and quantitative rationale of safety, and thus, of redefining the vulnerability governance. As a conclusion, we question the role of such STS vulnerability approach within the actual vulnerability governance. [less ▲]

In order to easily compare several populations on the basis of more than one feature, multivariate coefficients of variation (MCV) may be used as they allow to summarize relative dispersion in a single index. However, up to date, no test of equality of one or more MCV's has been developed in the literature. In this paper, several classical and robust Wald type tests are proposed and studied. The asymptotic distributions of the test statistics are derived under elliptical symmetry, and the asymptotic efficiency of the robust versions is compared to the classical tests. Robustness of the proposed procedures is examined through partial influence functions of the test statistic, as well as by means of power and level influence functions. A simulation study compares the performance of the classical and robust tests under uncontaminated and contaminated schemes, and the difference with the usual covariance homogeneity test is highlighted. As a by-product, these tests may also be considered in the univariate context where they yield procedures that are both robust and easy-to-use. They provide an interesting alternative to the numerous parametric tests of comparison of univariate coefficients of variation existing in the literature, which are, in most cases, unreliable in presence of outliers. The methods are illustrated on a real data set. [less ▲]

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

Mutualistic interactions between ant and aphid species have been the subject of considerable historical and contemporary investigations, the primary benefits being cleaning and protection for the aphids and carbohydrate-rich honeydew for the ants. Questions remained, however, as to the volatile semiochemical factor influencing this relationship. A recent study highlighted the role of bacterial honeydew volatile compounds in ant attraction. Here, ant’s ability to distantly discriminate two aphid species was investigated based on bacterial honeydew semiochemicals emissions using a two-way olfactometer. Both the mutualistic black bean aphid (Aphis fabae L.) and the non-myrmecophilous pea aphid (Acyrthosiphon pisum Harris) were found to be attractive for the black garden ant (Lasius niger L.). The level of attraction was similar in both assays (control versus one of the aphid species). However, when given a choice between these two aphid species, ants showed a significant preference for Aphis fabae. Honeydew volatiles, mostly from bacterial origins, are known to be a key element in ant attraction. Using the same olfactometry protocol, the relative attractiveness of volatiles emitted by honeydews collected from each aphid species and by bacteria isolated from each honeydew was in investigated. Again, ants significantly preferred volatiles released by Aphis fabae honeydew and bacteria. This information suggests that microbial honeydew volatiles enable ants to distantly discriminate aphid species. These results emphasize the importance of investigating the presence and potential effects of microbes in insect symbioses. [less ▲]

Introduction: The Attitudes to Aging Questionnaire (AAQ) was developed to measure attitudes toward the aging process as a personal experience from the perspective of older people. The present study aimed to validate the French version of the AAQ. Participants and methods: This study examined factor structure, acceptability, reliability and validity of the AAQ’s French version in 238 Belgian adults aged 60 years or older. In addition, participants provided information on demographics, self-perception of their mental and physical health (single items), quality of life (WHOQOL-OLD) and social desirability (DS-36). Results: Exploratory Factor Analysis produced a three-factor solution accounting for 36.9% of the variance. No floor or ceiling effects were found. The internal consistency, measured by Cronbach’s alpha coefficients for the AAQ subscales were 0.62 (Physical Change), 0.74 (Psychological Growth), and 0.75 (Psychosocial Loss). A priori expected associations were found between AAQ subscales, self-reported health and quality of life, indicating good convergent validity. The scale also showed a good ability to discriminate between people with lower and higher education levels, supporting adequate known-groups validity. Finally, we confirmed the need to control for social desirability biases when assessing self-reported attitudes toward one’s own aging. Conclusion: The data support the usefulness of the French version of the AAQ for the assessment of attitudes toward their own aging in older people. [less ▲]

Les mises en réseaux se développent de par le monde pour générer de l’innovation collaborative ; en France, elles prennent notamment la forme des « pôles de compétitivité ». La littérature a analysé le fonctionnement de ces réseaux territoriaux d’organisations. Mais alors que leur feuille de route consiste également à produire de l’innovation managériale, via des pratiques de gestion des ressources humaines qui se situent à l’interface d’organisations différentes, l’état des connaissances reste faible sur ce point. Les pôles de compétitivité français représentent-ils une forme organisationnelle innovant également en gestion des ressources humaines ? A l’aune d’une approche contextualiste, mais aussi d’un cadre théorique associant entrepreneuriat institutionnel et acteur-réseau, cet article interroge les modalités de l’innovation managériale dans douze pôles de compétitivité français. Il met en lumière la principale innovation managériale de ces réseaux territoriaux : l’innovation de processus. [less ▲]

WVO Quine questions the « myth » of an ideal realm of shared meanings which every national language would express in its own way. Against the hope of transparent translations, he insists on the necessity for building equivalences from one language to another through a strategy of reducing the differences in rationality among nations as much as possible. According to Quine, otherness is not insuperable impediment to meeting/encounter and mutual understanding ; by throwing our conceptual schemes on the other communities’ uses/practices – which of course involves some symbolic violence – gaps can always been narrowed. Similarly E. Laclau questions the traditional conception of political representation, which is seen as the transparent process of transmitting someone’s will or interests on another level. For this ideal conception of representation, Laclau substitutes a pragmatic conception which takes in account the irreducible gap between the actors as well as the constitutive opacity of the process of representation : the subject’s will is constituted within the process of representation and through the representative’s productive role. In order to be transposed at the decision-making level, the subject’s interests must be translated by the representative as well as be negotiated with the other represented interests. This implies that the initial will undergoes some identity transformations. [less ▲]

Intensive anchoring of leisure boats in seagrass meadows leads to mechanical damages. This anthropogenic impact creates bare mat patches that are not easily recolonized by the plant. Several tools are used to study human impacts on the structure of seagrass meadows but they are not able to assess the indirect and long term implication of mechanical destruction. We chose to investigate the possible changes in the substrate chemistry given contrasted boat impacts. Our observations show that hydrogen sulfide concentrations remain high at 15 and 20 m depth (42.6 µM and 18.8 µM) several months after the highest period of anchoring during the summer. Moreover, our multidisciplinary study reveals that anchoring impacts of large boats at 15 and 20 m depth can potentially change the seascape structure. By taking into account both structural and chemical assessments, different managing strategies must be applied for coastal areas under anthropogenic pressures. [less ▲]

We consider the multi-trip vehicle routing problem, in which each vehicle can perform several routes during the same working shift to serve a set of customers. The problem arises when customers are close to each other or when their demands are large. A common approach consists of solving this problem by combining vehicle routing heuristics with bin packing routines in order to assign routes to vehicles. We compare this approach with a heuristic that makes use of specific operators designed to tackle the routing and the assignment aspects of the problem simultaneously. Two large neighborhood search heuristics are proposed to perform the comparison. We provide insights into the configuration of the proposed algorithms by analyzing the behavior of several of their components. In particular, we question the impact of the roulette wheel mechanism. We also observe that guiding the search with an objective function designed for the multi-trip case is crucial even when exploring the solution space of the vehicle routing problem. We provide several best known solutions for benchmark instances. [less ▲]

In this paper, we present an optimized retrieval strategy for carbonyl sulfide (OCS), using Fourier transform infrared (FTIR) solar observations made at the high-altitude Jungfraujoch station in the Swiss Alps. More than 200 lines of the nu3 fundamental band of OCS have been systematically evaluated and we selected 4 microwindows on the basis of objective criteria minimizing the effect of interferences, mainly by solar features, carbon dioxide and water vapor absorption lines, while maximizing the information content. Implementation of this new retrieval strategy provided an extended time series of the OCS abundance spanning the 1995-2015 time period, for the study of the long-term trend and seasonal variation of OCS in the free troposphere and stratosphere. Three distinct periods characterize the evolution of the tropospheric partial columns: a first decreasing period (1995-2002), an intermediate increasing period (2002-2008), and the more recent period (2008-2015) which shows no significant trend. Our FTIR tropospheric and stratospheric time series are compared with new in situ gas chromatography mass spectrometry (GCMS) measurements performed by Empa (Laboratory for Air Pollution/Environmental Technology) at the Jungfraujoch since 2008, and with space-borne solar occultation observations by the ACE-FTS instrument on-board the SCISAT satellite, respectively, and they show good agreement. The OCS signal recorded above Jungfraujoch appears to be closely related to anthropogenic sulfur emissions. [less ▲]

The Unsteady Vortex Lattice Method (UVLM) is an approach widely used to estimate the aerodynamic loads in unsteady subsonic flows. It is based on modeling the camber surface of a lifting body by means of bound vortex rings. Even though this method has been known and used for several decades, there is little discussion of the modeling of the leading-edge suction in the literature. To address this concern, Simpson et al. [1] presented a comparison of two different ways to model this effect for the case of uncambered airfoils and wings in harmonic pitch or plunge motions. They concluded that the Joukowski method converges significantly faster than the Katz technique as the number of chorwise panels is increased. The present paper is an extension of the study by Simpson et al. to cambered lifting surfaces. It shows that the presence of camber can change radically the convergence performance of the two methods. For cambered wings, the Katz approach converges significantly faster than the Joukowski technique. [less ▲]

Incident reporting systems (IRSs) are used in many organisations as tools that promote safety by allowing to collectively learn from incidents. In this paper, we propose a social constructivist approach to learning from incidents, in which the focus is not purely on safety, but on the technology of incident reporting itself. We employ Wiebe Bijker’s work on the Social Construction of Technology to open up the analysis of a specific IRS in use at the Belgian Nuclear Research Center.

Such social constructivist perspective provides detailed insight into the practices of reporting and the meanings of learning from incidents.

Two experiments were conducted to reveal the effects of grain-induced subacute rumen acidosis (SARA) on thiamine status in blood and rumen fluid in dairy cows. In both experiments, 6 multiparous, rumen-fistulated Holstein dairy cows were used in a 2-treatment, 2-period crossover design. Each experimental period consisted of 21 d (total of 42 d). Experiment 1 was to investigate the effects of SARA on thiamine status in blood and rumen fluid. Treatments were either control (20% starch, dry matter basis) or SARA-inducing diet (SAID, 33.2% starch, dry matter basis). In experiment 2, the effects of dietary thiamine supplementation on attenuating SARA and ruminal fermentation characteristics in dairy cows were studied. All cows received the same SAID diet during the whole experimental period; treatments were with or without thiamine (180 mg of thiamine/kg of dry matter intake). In both experiments, rumen fluid samples were collected at 0, 3, 6, 9, and 12 h after morning feeding on d 21 and 42 of the experiments for measurement of pH, thiamine, volatile fatty acid, and lactate contents. Peripheral blood was also collected at 3 h after morning feeding on d 21 and 42 to measure thiamine, carbohydrate metabolites, and enzyme activities. In experiment 1, cows fed the SAID diet had lower ruminal and plasma thiamine concentrations and higher lactate than cows fed the control diet. The ruminal thiamine contents were positively related to pH and the concentrations of acetate in the rumen, and negatively correlated with the lactate contents. Experiment 2 demonstrated that ruminal pH and the concentrations of thiamine, acetate, and total volatile fatty acids in the rumen were increased, whereas ruminal lactate contents were reduced by thiamine supplementation. The concentrations of lactate and the activity of lactate dehydrogenase in blood were reduced in the thiamine supplemented group, and the opposite was true for the nonesterified fatty acids and α-ketoneglutarate dehydrogenase contents. In conclusion, the thiamine status was affected by SARA in dairy cows and ruminal infusion of thiamine could helpattenuate SARA by improving the proportions of ruminal volatile fatty acids and reducing lactate contents in rumen fluid and blood.

Objective: To investigate the relationship between psychological transition and adjustment to retirement and cognitive performances in older adults. Methods: The study’s sample was taken from the Approche Multidisciplinaire Int egr ee cohort, a French prospective study of retirees from agriculture, aged 65 and over, living in rural settings in southwestern France. The cross-sectional analyses were conducted on a sample of 590 elderly people without dementia at baseline and for whom information on perception of the work setting, experience of the retirement transition and adaptation to retirement life (nine variables) as well as neuropsychological measures (global cognitive functioning, episodic memory, verbal fluency, attention and psychomotor speed) were available at first visit. Results: Multivariable linear regression analyses, including nine variables related to retirement and adjusted for potential confounding factors, indicated that three of them positive consideration of former work situation, development of new activities during retirement and good adaptation to free time were associated with better cognitive performances. Conclusions: We found that several factors proved to be determinants of good cognitive functioning at retirement and could serve as a basis for the development of more efficient intervention programs aimed at helping retirees to maintain good cognitive functioning after retirement.

The famous Doignon-Bell-Scarf theorem is a Helly-type result about the existence of integer solutions to systems of linear inequalities. The purpose of this paper is to present the following quantitative generalization: Given an integer k, we prove that there exists a constant c(n,k), depending only on the dimension n and on the number k, such that if a bounded polyhedron {x in R^n : Ax <= b} contains exactly k integer points, then there exists a subset of the rows, of cardinality no more than c(n,k), defining a polyhedron that contains exactly the same k integer points. In this case c(n,0)=2^n as in the original case of Doignon-Bell-Scarf for infeasible systems of inequalities. We work on both upper and lower bounds for the constant c(n,k) and discuss some consequences, including a Clarkson-style algorithm to find the l-th best solution of an integer program with respect to the ordering induced by the objective function.

The dynamic behaviour of automotive drivetrains is significantly influenced by contacts occurring between the various parts. In this paper, a three-dimensional formulation is proposed to model unilateral and frictional contact conditions between two rigid planar rings. The magnitude of the contact force is determined by a penalty method. In a second step, a simple squeeze film model is developed to account for the damping effect produced by the lubricating oil filling the gap between the two contacting bodies. The relevance and the accuracy of these models are illustrated through the global multibody modelling of a TORSEN differential. [less ▲]

Allogeneic hematopoietic stem cell transplantation (alloHSCT) is a standard of care for patients with Philadelphia chromosome (Ph)–positive acute lymphoblastic leukemia (ALL). The introduction of tyrosine kinase inhibitors (TKIs) to first-line therapy has improved overall outcomes; however, a significant proportion of patients still relapse after alloHSCT. Posttransplant TKI maintenance was demonstrated to reduce the risk of relapse in a large retrospective study and, therefore, should be considered a valuable option. This consensus paper, written on behalf of the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation, presents an overview of clinical studies on the use of TKIs after alloHSCT and proposes practical recommendations regarding the choice of TKI, treatment timing, and dosage. It is hoped that these recommendations will become the state of art in this field and, more importantly, lead to a reduction of Ph-positive ALL relapse after alloHSCT. [less ▲]

Recent research suggests that sleepiness and mind-wandering—the experience of thoughts that are both stimulus-independent and task-unrelated—frequently co-occur and are both associated with poorer cognitive functioning. Whether these two phenomena have distinguishable effects on task performance remains unknown, however. To investigate this question, we employed the online experience sampling of mind-wandering episodes and subjective sleepiness during a laboratory task (the Sustained Attention to Response Task; SART), and also assessed mind-wandering frequency and sleep-related disturbances in daily life using self-report questionnaires. The results revealed that the tendency to experience mind-wandering episodes during the SART and daily life was associated with higher levels of daytime sleepiness and sleep-related disturbances. Importantly, however, mind-wandering and sleepiness were independent predictors of SART performance at both the within- and between-individuals levels. These findings demonstrate that, although mind-wandering and sleepiness frequently co-occur, these two phenomena have distinguishable and additive effects on task performance. [less ▲]

• Purpose This article aims at describing the evolution of scientific communication, largely represented by the publication process. It notes the disappearance of the traditional publication on paper and its progressive replacement by electronic publishing, a new paradigm implying radical changes in the whole mechanism. It aims also at warning the scientific community about the dangers of some new avenues and why, rather than subcontracting an essential part of its work, it must take back a full control of its production. • Design/methodology/approach The article reviews the emerging concepts in scholarly publication and aims to answer frequently asked questions concerning free access to scientific literature as well as to data, science and knowledge in general. • Findings The article provides new observations concerning the level of compliance to institutional open access mandates and the poor relevance of journal prestige for quality evaluation of research and researchers. The results of introducing an open access policy at the University of Liège are noted. • Social implications Open access is, for the first time in human history, an opportunity to provide free access to knowledge universally, regardless of either the wealth or the social status of the potentially interested readers. It is an essential breakthrough for developing countries. • Value Open access and Open Science in general must be considered as common values that should be shared freely. Free access to publicly generated knowledge should be explicitly included in universal human rights. There are still a number of obstacles hampering this goal, mostly the greed of intermediaries who persuade researchers to give their work for free, in exchange for prestige. The worldwide cause of Open Knowledge is thus a major universal issue for the 21st Century. [less ▲]

Co-simulation opens new opportunities to combine mature ElectroMagnetic Transients (EMT) and Phasor-Mode (PM) solvers, and take advantage of their respective high accuracy and execution speed. In this paper, a relaxation approach is presented, iterating between an EMT and a PM solver. This entails interpolating over time the phasors of the PM simulation, extracting phasors from the time evolutions of the EMT simulation, and representing each sub-system by a proper multiport equivalent when simulating the other sub-system. Various equivalents are reviewed and compared in terms of convergence of the PM-EMT iterations. The paper also considers the update with frequency of the Thévenin impedances involved in the EMT simulation, the possibility to compute the EMT solution only once per time step, and the acceleration of convergence through a prediction over time of the boundary variables. Results are presented on a 74-bus, 23-machine test system, split into one EMT and one PM sub-system with several interface buses. [less ▲]

The progress accomplished during the past decade in nonlinear system identi fication in structural dynamics is considerable. The objective of the present paper is to consolidate this progress by challenging the community through a new benchmark structure exhibiting complex nonlinear dynamics. The proposed structure consists of two o ffset cantilevered beams connected by a highly flexible element. For increasing forcing amplitudes, the system sequentially features linear behaviour, localised nonlinearity associated with the buckling of the connecting element, and distributed nonlinearity resulting from large elastic deformations across the structure. A finite element-based code with time integration capabilities is made available at http://sem.org/TDIV-Nonlin.asp. This code permits the numerical simulation of the benchmark dynamics in response to arbitrary excitation signals. [less ▲]

Purpose. To describe the gender, age, occupational status and diagnosis of dysphonic patients. Method. We retrospectively analyzed the medical records of 1079 patients examined at the Voice clinic of the University hospital of Liège in French-speaking Belgium. Results. Overall, seven out of 10 patients who attended the voice clinic for dysphonia were females. The patients’ ages ranged from 4 to 93 (mean=43.5). Females predominantly consulted at the age of 54 and males at the age of 9. Regarding the occupational status, workers represented more than half of our patients (53%), while 11.2% were unemployed, 15.4% were students, and 19.9% were retired. Regarding the diagnoses of the 1079 patients, nodules were the most common pathologies (n=182, 16.9% of the patients), prevailing in females (n=142, 18.8% of the females), encountered in 16.8% of the workers and 42.8% of the students consulting the voice clinic. Following nodules, laryngeal mobility disorders were diagnosed in 16.4% of the patients (n=177), mainly females (n=115), and was the most frequent diagnosis in retirees (n=75, 34.9%). Conclusions. The majority of the patients consulting the voice clinic for dysphonia were adult females, in their workforce, diagnosed with vocal nodules. The identification of the patients’ characteristics and diagnoses is important to develop treatments and prevention of dysphonia, estimate their costs, and allow comparisons across referral centers.

Novel chocolate spreads were enriched by soluble and insoluble dietary fibers from Tunisian Deglet Nour date seeds at 1, 2, 3, 4 and 5% levels in the conventional chocolate spread. Defatted Deglet Nour date seeds (DNDS), date seed soluble fiber concentrate (DSSFC) and date seed insoluble fiber concentrate (DSIFC) were characterized by high levels of dietary fibers (80 – 90%). Chocolate spread enriched with 5% of DSSFC presented the highest OBC (304.62%) compared to the control (102%). Whatever the DSIFC and DSSFC incorporation levels, no significant difference was recorded between the firmness, chewiness and adhesiveness of prepared chocolate spreads compared to the control (P<0.05). Sensory evaluation revealed that all prepared chocolate spreads enriched by DSIFC and DSSFC were accepted by panelists. These results indicated the value of date seeds as new source of dietary fibers to develop chocolate spread and could also improve health benefits and functional properties. [less ▲]

Partant de quelques textes dans lesquels S. Kracauer traite du rapport entre montage et réel, cet article tente de préciser et de problématiser l’ambivalence de Kracauer à l’égard de l’outil « montage », notamment dans le champ cinématographique, en ouvrant la réflexion par cette double question : comment définir un « mauvais usage » du montage et, à l’opposé, comment peuvent se mettre en place les conditions d’un « bon usage » du montage selon Kracauer ? Pour y répondre, les auteurs identifient d'abord, dans l’œuvre de Kracauer, les éléments explicites et implicites (montage textuel) qui permettent de saisir au plus près ce que serait, selon le philosophe et sociologue, le principe de réalité. Ensuite, une œuvre photographique, contemporaine des quelques textes évoqués, Menschen des 20. Jahrhunderts d’August Sander, permet de mieux circonscrire les possibles concrétisations de cette pensée en la mettant à l’épreuve d’une réalisation en images et en montage. [less ▲]

Three Earth-sized exoplanets were recently discovered close to the habitable zone of the nearby ultracool dwarf star TRAPPIST-1. The nature of these planets has yet to be determined, since their masses remain unmeasured and no observational constraint is available for the planetary population surrounding ultracool dwarfs, of which the TRAPPIST-1 planets are the first transiting example. Theoretical predictions span the entire atmospheric range from depleted to extended hydrogen-dominated atmospheres. Here, we report a space-based measurement of the combined transmission spectrum of the two inner planets made possible by a favorable alignment resulting in their simultaneous transits on 04 May 2016. The lack of features in the combined spectrum rules out cloud-free hydrogen-dominated atmospheres for each planet at 10-$\sigma$ levels; TRAPPIST-1 b and c are hence unlikely to harbor an extended gas envelope as they lie in a region of parameter space where high-altitude cloud/haze formation is not expected to be significant for hydrogen-dominated atmospheres. Many denser atmospheres remain consistent with the featureless transmission spectrum---from a cloud-free water vapour atmosphere to a Venus-like atmosphere. [less ▲]

Les Associations des Enfants et Jeunes Travailleurs du Burkina Faso (AEJT/BF) sont une représentation nationale du Mouvement Africain des Enfants et Jeunes Travailleurs (MAEJT), créé à la fin des années 1980. Le mouvement est fondé sur deux grands principes : les douze droits prioritaires des enfants et jeunes travailleurs et le principe du « protagonisme » (l’enfant travailleur comme acteur capable) . Ce chapitre présente et analyse le fonctionnement de ce mouvement au Burkina Faso, les changements qu’il a contribué à apporter à la question sociale du travail des enfants et les résultats de la mise en application des principes annoncés. S’appuyant sur une enquête ethnographique menée en son sein, le texte offre des données inédites sur les réalités d’un acteur collectif qui, en utilisant à son avantage la rhétorique de la « participation » des enfants (art.12, Convention des droits de l’enfant), a réussi à s’insérer dans l’arène nationale de la protection de l’enfance. Toutefois, la question de la place et du rôle des enfants ainsi que celle du “vieillissement” des membres sont quelques-uns des défis auxquels la section burkinabè du mouvement doit faire face.

The right dorsal premotor cortex (PMd) of humans has been reported to be involved in a broad range of motor and cognitive functions. We explored the basis of this behavioral heterogeneity by performing a connectivity-based parcellation using meta-analytic approach applied to PMd coactivations. We compared our CBP results to parcellations obtained through resting-state functional connectivity and probabilistic diffusion tractography,. Functional connectivity profiles and behavioral decoding of the resulting PMd subregions allowed characterizing their respective behavior profile. These procedures divided the right PMd into five distinct subregions that formed a cognitive-motor gradient along a rostro-caudal axis. In particular, we found (i) a rostral subregion functionally connected with prefrontal cortex, which likely supports high-level cognitive processes, such as working memory (ii) a central subregion showing a mixed behavioral profile and functional connectivity to parietal regions of the dorsal attention network, and (iii) a caudal subregion closely integrated with the motor system. Additionally, we found (iv) a dorsal subregion, preferentially related to hand movements and connected to both cognitive and motor regions, and (v) a ventral subregion, whose functional profile fits the concept of an eye-movement related field. In conclusion, right PMd may be considered as a functional mosaic formed by five subregions. [less ▲]

Estimation of glomerular filtration rate (eGFR) is essential to assess kidney function. Iodine containing contrast agents detection by HPLC has been proposed as a safe alternative for inulin or radioactive compounds. However, HPLC is a time-consuming and labour-intensive method. The aim of this study was to develop an assay for iohexol and iothalamate using capillary electrophoresis (CE). Iohexol and iothalamate were directly analysed by CE in serum and urine, using photometric detection (246 nm). Serum peak height was proportional to iohexol and iothalamate concentrations. Detection limits for iohexol and iothalamate were 10 mg/L and 5 mg/L. Limits of quantification were 13.0 mg/L and 15.0 mg/L. Within-run CVs were 4.9% and 6.5%; between-run CVs 3.1-9.9% and 3.8-13.7%. A good correlation was observed between CE and HPLC: y = 1.1703 x + 5.017 (iohexol) and y = 0.7807 x + 11.01 (iothalamate) [y = concentration obtained by CE (mg/L), x = concentration obtained by HPLC (mg/L)]. In addition, CE allowed to determine urinary iohexol concentration. Although the detection limit for CE was higher than for HPLC, CE can still be used for eGFR determination. Advantages of this high throughput method are the absence of sample pretreatment and a minimal sample volume requirement. This article is protected by copyright. All rights reserved. [less ▲]

n this paper, wee propose a model for regulatory capture that is based on information transmission and asymmetric information. In a three-tier model, a regulator is charged by a political principal to provide a signal for the type of a regulated firm. Only the firm can observe his type and the production of a correlated signal with a given accuracy is costly for the regulator. The firm can costlessly provide an alternative signal of lower accuracy that is presented to the regulator. In a self-enforcing equilibrium, the regulator transmits the firm-produced signal, internalizes its own savings in information cost and the firm enjoys higher information rents. The main feature of soft capture is that it is not based on a reciprocity of favors but on a congruence of interests between the firm and the regulator. [less ▲]
