Les champignons dans l’univers de Mario ; l’esthétique pixellisée de Minecraft ou d’Undertale ; le bleu azur dans Portal : autant de signes visuels qui, en tant que composantes d’un style ou d’une iconographie spécifique, signent l’identité esthétique d’une œuvre vidéoludique. Or, si les caractéristiques visuelles du jeu vidéo sont régulièrement évoquées, les réflexions qu’elles initient se limitent encore trop souvent à une évaluation des performances graphiques du jeu, voire à un commentaire sur l’appartenance ou non du médium au domaine artistique. Dans ce court article – qui marque une première étape, encore balbutiante, dans ce domaine de nos recherches –, nous souhaitons ouvrir un dialogue avec le lecteur sur le rôle de l’esthétique vidéoludique, à travers l’analyse d’une œuvre. Loin d’être anecdotique, la dimension esthétique d’un jeu joue un rôle essentiel dans la co- construction d’autres composantes du dispositif ludique, telles que la jouabilité ou la narration – le terme « esthétique » ne désignant donc pas ici le jugement de goût ou le beau, mais l’ensemble des caractéristiques formelles constituant l’identité visuelle du jeu. Inscrite au cœur de la structure des objets-jeux (du game), l’esthétique vidéoludique a également un impact tant sur l’expérience de jeu que sur la posture des joueurs (le play). Cet article se propose d’explorer ce rôle potentiel de l’esthétique à travers un cas d’étude : le jeu INSIDE (Playdead, 2015). Si notre analyse peut se déployer au sein de nombreuses œuvres vidéoludiques, l’exemple d’INSIDE se distingue par une particularité : son esthétique constitue un des piliers de la narration et d’une réflexivité qui marque profondément le gameplay du jeu – réflexivité qui a été étudiée dans un précédent article (Barnabé et Delbouille ; 2017). Plonger au cœur d’INSIDE permet donc non seulement d’illustrer la façon dont l’esthétique peut être mobilisée pour renforcer les autres dimensions du jeu, mais également la nécessité d’étudier l’esthétique propre au médium vidéoludique – au-delà de la simple qualité graphique ou du jugement de goût.

Hydrodistillation assisted by microwave (HDAM) and Head space solid phase micro-extraction (HSSPME) of Myristica fragrans houtt (MF) were investigated. A kinetic study was performed for MF seeds using two techniques (HDAM: Hydrodistillation assisted by microwave and SDAM: steam distillation assisted by microwave). The effect of the cryogenic grinding (CG) showed differences in yields and composition of volatile oils compared to the simple grinding (SG). HDAM–SG (3.4%) and SDAM–SG (2.55%) allowed extraction of substantial amounts of volatile oils in less time compared with HDAM–CG (4.75%) and SDAM–CG (3.8%). The kinetic study (differential and accumulated yields) of essential oil extraction was quantitatively and qualitatively performed showing a significant variation of composition with the extraction time, especially for accumulated yields such as sabinene (31.48–38.78%), α-pinene (12.74–14.09%) and β-pinene (10.01–12.11%). Similarly, the HS-SPME–GC–MS analysis showed also a significant variation of MF seeds volatile composition according some parameters as the type of fibre coating (PDMS: Polydimethylsiloxane and PDMS– DVB: Polydimethylsiloxane divenylbenzene), particle size, grinding mode and the mass used. The chemical groups (monoterpenoids, aliphatic and aromatic alcohols and esters) showed specific behaviour in SPME analysis. SPME sampling parameters were optimized for these components. [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.

Resolving population genetic structure is challenging, especially when dealing with closely related populations. Although Principal Component Analysis (PCA)-based methods and genomic var- iation with single nucleotide polymorphisms (SNPs) are widely used to describe shared genetic an- cestry, improvements can be made targeting fine-level population structure. This work presents an R package called IPCAPS, which uses SNP information for resolving possibly fine-level population structure. The IPCAPS routines are built on the iterative pruning Principal Component Analysis (ipP- CA) framework to systematically assign individuals to genetically similar subgroups. Our tool is able to detect and eliminate outliers in each iteration to avoid misclassification. It can be extended to de- tect subtle subgrouping in patients as well. In addition, IPCAPS supports different measurement scales for variables used to identify substructure. Hence, panels of gene expression and methylation data can be accommodated. [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 ▲]

Prosumers are households that are both producers and consumers of electricity. A prosumer has a grid-connected decentralized production unit (DPU) and makes two types of exchanges with the grid: energy imports when the local production is insufficient to match the local consumption and energy exports when local production exceeds it. There exists two systems to measure the exchanges : a net metering system that uses a single meter to measure the balance between exports and imports and a net purchasing system that uses two meters to measure separately power exports and imports. Both systems are currently used for residential consumption. We build a model to compare the two metering systems. Under net metering, the price of exports paid to prosumers is implicitly set at the price of the electricity that they import. We show that net metering leads to (1) too many prosumers, (2) a decrease in the bills of prosumers, compensated via a higher bill for traditional consumers, and (3) a lack of incentives to synchronize local production and consumption.

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.

Shallow reservoirs are used for multiple purposes, such as storm water retention and trapping of sediments. Reliable predictions of the flow fields are necessary to inform the design and operation of these structures. Using numerical simulations, we performed a systematic analysis of the influence of the location of the inlet and outlet on the flow fields developing in rectangular shallow reservoirs of various sizes. Depending on the relative location of the inlet and outlet with respect to the reservoir centreline, contrasting flow patterns are obtained, involving either no flow reattachment, or a jet reattached on either of the reservoir sidewalls. The results reveal also the occurrence of bi-stable flow configurations, i.e. different steady state flow fields are reached depending on the flow history. This is of high relevance for the design of shallow reservoirs as such configurations should certainly be avoided to achieve a robust hydraulic sizing of the reservoir. [less ▲]

This paper focuses on the interpolation of the kinematic fields describing the configuration of geometrically exact beams, namely, the position and rotation fields. Two kinematic representations are investigated: the classical approach that treats the displacement and rotation fields separately and the motion approach that treats those two fields as a unit. The latter approach is found to be more consistent with the kinematic description of beams. Then, two finite element interpolation strategies are presented and contrasted. The first interpolates the displacement and rotation fields separately, whereas the second interpolates both fields as a unit, in a manner consistent with the motion approach. The performance of both strategies is evaluated in light of the fundamental requirements for the convergence of the finite element method: the ability to represent rigid-body motions and constant strain states. It is shown that the traditional uncoupled interpolation scheme for the position field approximates that based on the motion approach and that the coupling induced by the interpolation of motion yields superior convergence rates for the representation of constant strain states. This property is known to lead to finite elements that are less prone to the locking phenomenon. [less ▲]

Comprehensive protocols have been developed for calibrating, testing, and converting Faraday rotation data to magnetic field maps.

A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations and finite fields variations. The multi-physics DG formulation is shown to satisfy the consistency condition, and the uniqueness and optimal convergence rate properties are derived under the assumption of small deformation. First the numerical properties are verified on a simple numerical example, and then the framework is applied to simulate the response of smart composite materials in which the shape memory effect of the matrix is triggered by the Joule effect.

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 ▲]

Dispersal (i.e., movement from a natal or breeding site to another breeding site) is a central process in ecology and evolution as it affects the eco-evolutionary dynamics of spatially structured populations. Dispersal evolution is regulated by the balance between costs and benefits, which is influenced by the individual phenotype (i.e., phenotype-dependent dispersal) and environmental factors (i.e., condition-dependent dispersal). Even though these processes have been extensively studied in species with simple life cycles, our knowledge about these mechanisms in organisms displaying complex life cycles remains fragmentary. In fact, little is specifically known about how the interplay between individual and environmental factors may lead to alternative dispersal strategies that, in turn, lead to the coexistence of contrasted site fidelity phenotypes. In this paper, we examined breeding dispersal in a pond-breeding amphibian, the great crested newt (Triturus cristatus), within usual walking distances for a newt. We took advantage of recent developments in multi-event capture-recapture models and used capture-recapture data (946 newts marked) collected in a spatially structured population occupying a large pond network (73 ponds). We showed a high rate of breeding site infidelity (i.e., pond use) and the coexistence of two dispersal phenotypes, namely, a highly pond faithful phenotype and a dispersing phenotype. Individuals that were site faithful at time t-1 were therefore more likely to remain site faithful at time t. Our results also demonstrated that the probability that individuals belong to one or the other dispersal phenotypes depended on environmental and individual factors. In particular, we highlighted the existence of a dispersal syndrome implying a covariation pattern among dispersal behavior, body size, and survival. Our work opens new research prospects in the evolution of dispersal in organisms displaying complex life cycles and raises interesting questions about the evolutionary pathways that contribute to the diversification of movement strategies in the wild.

In this case study, we study the generation of warning waves with prescribed characteristics in a mountain stream. We determine which dam release will generate the desired warning wave. We solve this inverse problem following a two-model approach. An analytical kinematic model is used for a preliminary design of the dam release and a detailed two-dimensional (2D) fully dynamic model is used to converge to the final solution. Although the presented case study is far from an idealized academic case, the analytical model performs well and, beyond its role for preliminary design, turns out to be of prime interest for both understanding and discussing the results of the detailed 2D model. The complex interactions between the release hydrograph, the geometry of the river and the friction formula are brought to light by the analytical model, which highlights the complementarity of both models and the usefulness of such a two-model approach.

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

The identification of a psychopathological structure results in a better understanding of Jeanne’s clinical situation and helps formulate psychotherapeutic and prophylactic recommendations. We suggest that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism pertaining to anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial consists in a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Aim: The Psychopathy Checklist-Revised (PCL-R) is the most studied and validated instrument to measure psychopathy. We aimed to explore its items content invariance to forensic schizophrenic subjects. Method: We examined the PCL-R protocol of 15 male forensic schizophrenic subjects and attributed a score of sensitivity to psychotic symptomatology to each item score. Results: Results suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. Some items more systematically positively influenced by psychotic symptoms (e.g. Shallow Affect, Lack of Remorse or Guilt), while others were negatively influenced (e.g. Promiscuous Sexual Behavior, Glib and Superficial Charm), or not influenced at all (e.g. Criminal Versatility). Conclusions: The current study suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. We discuss both psychometric and conceptual implications for the measurement of psychopathy when a diagnosis of schizophrenia has been established. [less ▲]

This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No pier effect or air venting is considered in the study. The velocity field is measured by Bubbles Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparison of measured velocities between both spillways indicates low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity calculated from the relative pressure considering a potential flow finally emphasizes that bottom pressure amplitudes seem overestimated for the larger spillway, while an averaging effect might operate for the pressure measurements on the smaller spillway.

Objectives: To examine beliefs about cracking sounds heard during highvelocity lowamplitude (HVLA) thrust spinal manipulation in individuals with and without personal experience of this technique. Methods: We included 100 individuals. Among them, 60 had no history of spinal manipulation, including 40whowereasymptomatic with or without a past history of spinal pain and 20whohad nonspecific spinal pain. The remaining 40 patients had a history of spinal manipulation;amongthem, 20 were asymptomatic and 20 had spinal pain. Participants attended a oneonone interview during which they completed a questionnaire about their history of spinal manipulation and their beliefs regarding sounds heard during spinal manipulation. Results: Mean age was 43.5±15.4 years. The sounds were ascribed to vertebral repositioning by 49% of participants and to friction between two vertebras by 23% of participants; only 9% of participants correctly ascribed the sound to the release of gas. The sound was mistakenly considered to indicate successful spinal manipulation by 40% of participants. No differences in beliefs were found between the groups with and without a history of spinal manipulation. Conclusions: Certain beliefs have documented adverse effects. This study showed a high prevalence of unfounded beliefs regarding spinal manipulation. These beliefs deserve greater attention from healthcare providers, particularly those who practice spinal manipulation. [less ▲]

Les troubles du spectre autistique comportent des comorbidités multiples, dont des altérations du sommeil. Ils sont importants à caractériser dans cette population, car ils peuvent avoir un impact négatif sur les comportements diurnes. Par ailleurs, ils entrainent souvent des difficultés au sein de la famille.

The principal aim of this study was to contribute more to the knowledge of the eastern Moroccan honey by means of the analysis of physicochemical characteristics with different flora of eastern Morocco. Thirty one honey samples were collected from beekeepers in different regions of eastern Morocco. In this study, pH, free acidity, electrical conductivity (EC), water content, diastase, hydroxymethylfurfural (HMF) and Protein content were all determined in different types of eight flora honey jujube, Multifloral, Citrus, Eucalyptus, thyme, carob, lavender and Rosemary. The moisture shows values of 15.39% and 19.37%, pH between 3.53 and 4.94, the free acidity ranges between 5.77 and 19.47 meq/kg, hydroxymethylfurfural (HMF) content shows values between 3.98 and 56.14mg/kg; diastase values were between 6.98 and 21.17 Gothe; electrical conductivity between 108 and 626 μs/cm and Saccharase content values range between 1.16-11.91 U.E/kg. A statistical analysis was carried out to classify eight types of honeys, and identified the most significant parameters, using analysis of variance, principal component analysis (PCA). PCA showed that the cumulative variance was 71.91%. The present study revealed that eastern Morocco honey is a good quality. [less ▲]

One of the main consequences of the Roman conquest was the diffusion of the Latin language and of Roman culture throughout the conquered countries. According to many texts of the imperial period, Latin became a universal language during the Imperium Romanum. But what is the reality? Did Rome develop any linguistic policies? There is some evidence to show that Rome’s response regarding the sociolinguistic problems that arose under its rule was to be flexible and willing to adapt to the specific requirements of each situation. Under the Republic and the early Principate, there was, in fact, a great flexibility in language use by the Romans in their dealings with the Greek world. Even though Latin-Greek bilingualism was widespread among the Romans of the Republic and the early Principate, in the public context, Latin maintained a high-level role because it represented the language of Rome’s power. In spite of this flexible approach to language use, a natural competition developed between the language of the dominant and the language of the dominated. In the Occident, Latin became the only vehicle of communication, both oral and written, whereas in the Orient, one notes a paradoxical situation: the Hellenization of the Romans due to the high cultural position of the Greek language. However, this dichotomy did not produce a division of the Roman Empire into two impenetrable parts, closed to mutual linguistic and cultural influences, but rather, it generated a more complicated situation, especially in the Oriental part of the Empire. It is this situation that will be analyzed in the present paper. [less ▲]

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 theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain. [less ▲]

The starting point of this article is the weak usage of rail freight in Belgium and Europe, both as a sustainable mode of land transportation in itself as well as a part of the intermodal chain. The results are obtained by transversal research on rail freight transport in Belgium, taking into account the European context. This interdisciplinary research develops a road map for the creation of three integrated scenarios: a best case, medium case and worst case scenario for rail freight development, based on a detailed SWOT (strength, weakness, opportunities, threats) analysis. It includes the most probable future developments for rail freight transport and hinterland connections. These developments are obtained from literature review and discussions with a heterogeneous panel of experts in the fields of (i) optimal corridor and hub development, (ii) macroeconomic impact, (iii) sustainability, (iv) effective market regulation and (v) governance and organization for a well-functioning intermodality. The Delphi approach is used in combination with a survey analysis. Frequency tables and the H-index allow defining a ranking and selection of SWOT elements. The obtained scenarios allow future research to quantify and measure the impact of future developments and decisions towards the Belgian rail freight market. [less ▲]

Understanding how the productivity of water can be increased is widely accepted to be a high priority where water resources are currently scarce and/or over-exploited in China. As the primary data source, MODIS remote sensing, statistics, meteorological data, crop growth period data and ground truth-data from Jan. 2011 to Dec. 2012 were used in actual evapotranspiration estimation, yields rasterizing, and water productivity calculation for winter wheat in the Huang-Huai-Hai Plain (3H Plain). The statistical data were synthesized to calculate district-state-level land productivity, which is then further extrapolated to pixel-level values using a MODIS NDVI image, based on a crop dominance map. Spatial variation of crop water productivity was investigated in order to reveal the key factors of crop water productivity. In addition, the relationship between water productivity and actual evapotranspiration and in subsequence yield for winter wheat was discussed in 3H Plain. The main results indicated that the SEBAL is suitable for estimating evapotranspiration in winter wheat based on the comparation between evapotranspiration measured by Yucheng (in Shandong province). The regional average value of water productivity for winter wheat was detected to be 1.21kg·m-3, with the higher value in Beijing, Tianjin, north part of Shandong province and south part of Hebei province. The pronounced relationship of spatial correlation of the yield and water productivity for winter wheat indicated that the increasing yield governed the increment of water productivity for winter wheat in the coastal land-farming-fishing area (zone1), low plain-hydropenia irrigable land and dry land zone (zone2) and basin- irrigable land and dry land (zone5). The increasing water productivity for winter wheat was recognized to be controlled by rather the increment of yield than the reduction of actual evapotranspiration for winter wheat in the piedmont plain-irrigable land (zone2). Whereas, the pronounced relationship of negative correlation of water productivity and actual evapotranspiration for winter wheat described that only the reduction of actual evapotranspiration was responsible for the increment of water productivity for winter wheat in hill-wet hot paddy-paddy field (zone6). The results is expected to provide a basis information for agricultural water management, improvement of crop water productivity and choice of adaptive mechanism under climate change in Huang-Huai-Hai plain.

Over the years, polymer analyses using ion mobility-mass spectrometry (IM-MS) measurements have been performed on different ion mobility spectrometry (IMS) setups. In order to be able to compare literature data taken on different IM(-MS) instruments, ion heating and ion temperature evaluations have already been explored. Nevertheless, extrapolations to other analytes are difficult and thus straightforward same-sample instrument comparisons seem to be the only reliable way to make sure that the different IM(-MS) setups do not greatly change the gas phase behavior. We used a large range of degrees of polymerization (DP) of poly(ethylene oxide) PEO homopolymers to measure IMS drift times on three different IM-MS setups: a homemade drift tube (DT), a trapped (TIMS) and a travelling wave (T-Wave) IMS setup. The drift time evolutions were followed for increasing polymer DPs (masses) and charge states and they are found to be comparable and reproducible on the three instruments. [less ▲]

In section 2 I present Brentano’s mereological solution and in section 3 I review his main pro-arguments. Eventually, in section 4 I consider some Jamesian objections to the mereological approach. I argue the notion of ‘mental parts’ can be given a rather innocuous meaning by being conceived of as the expression of conceptual distinctions grounded in similarity and contrast relations between total mental phenomena.

This work presents a biased random-key genetic algorithm (BRKGA) to solve the electric distribution network reconfiguration problem (DNR). The DNR is one of the most studied combinatorial optimization problems in power system analysis. Given a set of switches of an electric network that can be opened or closed, the objective is to select the best configuration of the switches to optimize a given network objective while at the same time satisfying a set of operational constraints. The good performance of BRKGAs on many combinatorial optimization problems and the fact that it has never been applied to solve DNR problems are the main motivation for this research. A BRKGA is a variant of random-key genetic algorithms, where one of the parents used for mating is biased to be of higher fitness than the other parent. Solutions are encoded by using random keys, which are represented as vectors of real numbers in the interval (0,1), thus enabling an indirect search of the solution inside a proprietary search space. The genetic operators do not need to be modified to generate only feasible solutions, which is an exclusive task of the decoder of the problem. Tests were performed on standard distribution systems used in DNR studies found in the technical literature and the performance and robustness of the BRKGA were compared with other GA implementations.

Even if insect pest populations can be reduced by increasing plant diversity through intercropping, natural enemies are not always favored in such systems. Alternatively, semiochemical substances have been tested to enhance biological control, with inconsistent results. Combining both strategies can be an interesting way to maximize pest control. In this work, a 2-year setup involving wheat–pea strip intercropping combined with the release of E-b-farnesene (EBF) or methyl salicylate (MeSA) was tested as a push–pull strategy to simultaneously repel aphids and attract beneficials. Two types of slow-release formulation (i.e., oil and alginate beads) containing EBF or MeSA were deployed with the intercropping. The abundance of aphids was significantly decreased, while hoverfly larvae and mummified aphids increased on both pea plants and wheat tillers by the release of oil-formulated EBF and MeSA. The proportion parasitism of the aphid-parasitism rate [mummies/(aphids + mummies)] was also increased by treating both crops in both years. Releasing EBF through oil rather than alginate beads proved significantly better for attracting natural enemies and reducing aphids. Aphids were negatively correlated with the density of hoverflies (both adults and larvae) and numbers of mummies. All these results showed that combining intercropping with the release of EBF or MeSA formulated in oil can significantly reduce aphid density and attract their natural enemies. Therefore, the combination of both strategies could help farmers reduce the use of insecticides. [less ▲]

Plant rennets hold an important position amongst various coagulants used in cheese technology. The selection of a suitable plant coagulant is important due to the increasing global demands of cheese alongside reduced supply of calf rennet. Thus, a literature synthesis is presented to investigate recent achievements on their functional properties and enzymatic role in cheese making. Efforts have also been done to compare certain rheological and sensory properties of final products, arising from some plant and animal based rennets. In fact, some coagulants such as actinidin or dubiumin produce cheeses with sensory qualities similar to those produced by animal rennet. Others, like ginger, cucumisin or hieronymain proteases contribute to develop very different textures and flavors, due to excessive proteolytic activity and production of bitter peptides. For milk-clotting enzymes with high non-specific action, several improvement strategies have been developed to produce cheeses with sensory properties close to those of animal rennet. For example, the mixture of coagulants (cardosins/chymosin), the selection of appropriate milk or its ultrafiltration, as well as the increase of salting time of cheese during ripening could be efficient ways to improve texture and reduce bitterness. Concerning cheeses with high yield loss, the whey could be used for a traditional production of whey cheese. To conclude, the selection of appropriate plant rennet with high MCA/PA ratio and the optimization of all coagulation parameters play a central role in manufacturing cheese with superior rheological and sensory properties.

INTRODUCTION: Vitamin D insufficiency, defined by a 25-hydroxyvitamin D (25OHD) serum concentration<20ng/mL, is highly frequent in the French general population, especially between November and April. The aim of this study was to evaluate whether 80,000 IU vitamin D3 every month during this period of the year was able to maintain a 25OHD level between 20 and 60ng/mL in apparently healthy subjects whatever their basal vitamin D status. METHODS: Ninety-eight subjects volunteered to receive an 80,000 IU vitamin D3 dose every month between November 2014 and April 2015. Serum 25OHD, calcemia and calciuria were measured just before the first dose (Month 0), just before the 4th dose (M4), and one month after the 6th dose (M7). RESULTS: At M0, 25OHD was 17.5+/-9.5ng/mL. Sixty subjects (61.2%) had a 25OHD<20ng/mL and 25 (25.5%) had a 25OHD<10ng/mL. 25OHD increased significantly at M4 (35.3+/-8.0ng/mL) and M7 (40.1+/-8.5) without change in calcemia and calciuria. At M4, 2 subjects had a 25OHD slightly below 20ng/mL (17.6 and 19.7ng/mL), and none had a concentration>60ng/mL. At M7, all had a serum 25OHD>20ng/mL and 2 subjects had a value slightly above 60ng/mL (62.1 and 63.2ng/mL). CONCLUSION: A monthly supplementation with 80,000 IU vitamin D3 between November and April corrected vitamin D insufficiency in subjects in whom it was initially very frequent, without overdosing. This protocol is simple, safe and costless, and can be easily implemented when physicians detect risk factors for hypovitaminosis D in patients for whom a 25OHD measurement is not indicated.

The study proposes a comparative analysis of the French-language and Flemish/Dutch versions of the international ballad deriving from the Danish 'Moderen under Mulde' (Dgf 89), and on this basis identifies three French-language texts recorded in North-east France and Wallonia yet showing closer affinities to the neighbouring Flemish tradition. In the light of both textual traditions, their unilateral adoption of Flemish motifs and their enhancing effect suggests deliberate selection rather than mere geographical proximity or bilingualism as explanation for their hybridization.

We study retirement incentives with an augmented reduced form option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentive and household composition.

A two-level real-time voltage control scheme is proposed to keep voltages within specified limits in distribution grids using Distributed Generation Units (DGUs). It combines a local and a centralized control of their reactive powers. The local control provides fast response after a disturbance, reducing its impact and enhancing voltage quality. The centralized control uses measurements collected throughout the network to bring the voltages inside tighter limits and balance the various DGU contributions. To this purpose, it adjusts in a coordinated way their reactive power set-points, taking into account the local controls. This discrete control solves at each time step a multi-time-step constrained optimization inspired of Model Predictive Control. The method effectiveness is demonstrated on a 75-bus test system hosting 22 DGUs. [less ▲]

¿Cómo el poeta de Las Flores del Mal paso de ser un autor proscrito, y en consecuencia sospechoso, al autor perseguido e incomprendido que ha inmortalizado la historia literaria? ¿Cómo Baudelaire pudo desviar a su favor una circunstancia que, a primera vista, era desafortunada? Baudelaire supo utilizar el escándalo que provocó la publicación de Las Flores del Mal para promover su figura pública. Un análisis de las posturas discursivas desplegadas por Baudelaire y por sus pares durante y después del proceso nos permitirá comprender mejor la inversión que el poeta hace de su condenación al transformar la sanción penal y moral, y la exclusión a la que ésta conduce, en un signo de su grandeza y de su gloria póstuma.

BACKGROUND: Adequate motor control is considered important for spinal stability and the prevention of low back pain in adulthood and in childhood. OBJECTIVE: Given that the sitting position can affect proprioception, this study aimed to evaluate the influence of using at school a triangular and dynamic cushion on schoolchildren’s trunk motor control. METHODS: Thirty 8-year-old schoolchildren were randomized into a control group (n=15) and a “cushion group” (n=15), in which the children used the cushion for one year and a half. At the end of this period, a 3D-analysis was used to assess lumbar spine proprioception by means of a trunk repositioning task performed blindfolded in a seated position in two conditions (on a stable and on an unstable surface). RESULTS: The schoolchildren in the cushion group performed better at the trunk repositioning task (p=0.02) and hold their lumbar lordosis (p=0.03) better than the control children, in both conditions (stable and unstable). CONCLUSIONS: This preliminary study suggests that daily use of a triangular dynamic cushion has a beneficial impact on children’s lumbar proprioception. Further studies are needed to confirm these results and investigate the effectiveness of its use to prevent low back pain in adulthood. [less ▲]

Structuring poly(ionic liquid)s (PILs) into porous materials or swelling PILs with free ionic liquids (ILs) has received specific attention recently and contributed to improve the performances of these materials used in a wide range of applications. The present work aims to take benefit of both approaches and produce macroporous PIL/IL gels in a single step through an innovative emulsion-templated polymerization method based on supercritical carbon dioxide (scCO2). More precisely, ILs vinyl monomers and crosslinkers were polymerized in the presence of non polymerizable ILs within the outer phase of a CO2-in-ILs high internal phase emulsion (HIPE). Specific macromolecular surfactants were synthesized by controlled radical polymerization techniques and tested for the stabilization of the CO2-in-ILs emulsions. While optimizing the polymerization conditions, we found that adding a limited amount of water in the medium was beneficial for the emulsion stability. Overall, this straightforward process gave access to macroporous polyHIPEs composed of poly(vinyl imidazolium) networks swollen by ‘free’ vinyl imidazolium-based ILs having interesting properties such as switchable polarity upon simple anion exchange reaction.

During the last years, chemistry was involved in the worldwide effort toward environmental problems leading to the birth of green chemistry. In this context, green analytical tools were developed as modern Supercritical Fluid Chromatography in the field of separative techniques. This chromatographic technique knew resurgence a few years ago, thanks to its high efficiency, fastness and robustness of new generation equipment. These advantages and its easy hyphenation to MS fulfill the requirements of bioanalysis regarding separation capacity and high throughput. In the present paper, the technical aspects focused on bioanalysis specifications will be detailed followed by a critical review of bioanalytical supercritical fluid chromatography methods published in the literature.

Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This multi-purpose high-contrast visible and near-infrared (R- to K-band) instrument is not only intended to serve as a VLT-class "planet-imager" instrument in the Northern hemisphere, but also to operate as a technology demonstration testbed ahead of the ELTs-era, with a particular emphasis on small inner-working angle (IWA) coronagraphic capabilities. The given priority to small-IWA imaging led to the early design choice to incorporate focal-plane phase-mask coronagraphs. In this context, a test H-band vector vortex liquid crystal polymer waveplate was provided to SCExAO, to allow a one-to-one comparison of different small-IWA techniques on the same telescope instrument, before considering further steps. Here we present a detailed overview of the vector vortex coronagraph, from its installation and performances on the SCExAO optical bench, to the on-sky results in the extreme AO regime, as of late 2016/early 2017. To this purpose, we also provide a few recent on-sky imaging examples, notably high-contrast ADI detection of the planetary-mass companion \kappa Andromedae b, with a signal-to-noise ratio above 100 reached in less than 10 mn exposure time.

Objective: We here aimed at characterizing heart–brain interactions in patients with disorders of consciousness. We tested how this information impacts data-driven classification between unresponsive and minimally conscious patients. Methods: A cohort of 127 patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS; n570) and minimally conscious state (MCS; n557) were presented with the local–global auditory oddball paradigm, which dis- tinguishes 2 levels of processing: short-term deviation of local auditory regularities and global long-term rule viola- tions. In addition to previously validated markers of consciousness extracted from electroencephalograms (EEG), we computed autonomic cardiac markers, such as heart rate (HR) and HR variability (HRV), and cardiac cycle phase shifts triggered by the processing of the auditory stimuli. Results: HR and HRV were similar in patients across groups. The cardiac cycle was not sensitive to the processing of local regularities in either the VS/UWS or MCS patients. In contrast, global regularities induced a phase shift of the cardiac cycle exclusively in the MCS group. The interval between the auditory stimulation and the following R peak was significantly shortened in MCS when the auditory rule was violated. When the information for the cardiac cycle modulations and other consciousness-related EEG markers were combined, single patient classification performance was enhanced compared to classification with solely EEG markers. Interpretation: Our work shows a link between residual cognitive processing and the modulation of autonomic somatic markers. These results open a new window to evaluate patients with disorders of consciousness via the embodied paradigm, according to which body–brain functions contribute to a holistic approach to conscious processing.
