Le projet STARECAPMED (STAtion of Reference and rEsearch on Change of local and global Anthropogenic Pressures on Mediterranean Ecosystems Drifts) a pour objectif (i) d’améliorer la compréhension du fonctionnement des différents écosystèmes marins côtiers présents en Méditerranée et (ii) de décrire l’influence des activités humaines sur les processus qui gouvernent ce fonctionnement. La baie de Calvi, par sa situation exceptionnelle, est un site de référence de la Directive Européenne Cadre sur l’Eau (DCE), du monitoring de l’eutrophisation et de la contamination par les éléments traces. La Station de recherches océanographiques STARESO, implantée dans la baie depuis près de 50 ans, possède un accès unique à la mer et de nombreuses facilités logistiques. Elle a développé au fil du temps une expertise scientifique reposant notamment sur l’acquisition de longues séries temporelles de données environnementales. Ensemble, Baie et Station s’intègrent en un site atelier dédié à l’évaluation de l’état de santé des écosystèmes marins côtiers de Méditerranée Nord-Occidentale. En particulier, différents indices et indicateurs y sont développés en collaboration avec de nombreux laboratoires partenaires. Ainsi, nous avons développé, d’une part, une version non destructive de l’indice PREI (Posidonia Rapid Easy Index) d’évaluation de la qualité des eaux côtières reposant sur le suivi des herbiers à Posidonia oceanica, et d’autre part, deux indices d’évaluation de l’impact des ancrages, puis testé   l’indice EBQI (Ecosystem Based Quality Index), une approche sur la diversité écologique. Les indices TEPI (Trace Element Pollution Index) et TESVI (Trace Element Spatial Variation Index) permettent d’évaluer la contamination par les éléments traces. Le BeMSI (BEnthic Methodology Simplification) est un nouvel indicateur de la qualité du milieu défini à partir de la composition des peuplements macrobenthiques des substrats meubles et plus généralement, l’indice LIMA traduit l’attrait paysager et la richesse patrimoniale du benthos méditerranéen entre 0 et –40 m. Quant à l’indice ICAR (Indice paysager CAulerpa Racemosa), il permet d’évaluer les niveaux de colonisation par l’algue invasive Caulerpa cylindracea. Enfin, une approche innovante reposant sur l’enregistrement des sons permet d’évaluer la qualité du milieu à partir d’un paysage acoustique sous-marin. En conclusion, le développement et l’application combinée de ces différents indices et indicateurs développés dans le cadre du programme pluridisciplinaire STARECAPMED fournissent une estimation globale des états du milieu côtier méditerranéen à différents niveaux d’organisation, depuis l’espèce jusqu’à l’écosystème. De plus, leur mise en œuvre dans ce même site atelier privilégié permet de les confronter, de les ajuster et de les intercalibrer pour à terme les proposer aux gestionnaires du milieu côtier.

This paper introduces an open implementation of DICOM for whole-slide microscopic imaging, following Supplement 145 of the DICOM standard. The software is divided into two parts: (a) a command-line tool to convert an whole-slide image to the DICOM format, and (b) a zero-footprint Web interface to display such DICOM images. The software architecture leverages the DICOM server Orthanc. The entire framework is available as free and open-source software. The existence of this software supports the development of digital pathology and telepathology in clinical environments, featuring a smooth integration with existing EHR and PACS solutions. [less ▲]

For several years, the number of Global Navigation Satellite Systems (GNSS) has been increasing, opening new perspectives in the field of precise positioning. Particularly, the European system, Galileo, is experiencing a prompt expansion with the launch, in 2015 and 2016, of 8 satellites belonging to the new Full Operational Capability (FOC) generation. Broadcasting new signals, with new modulations, the first studies addressing this system reveal promising level of precisions on both code and carrier phase observables. Yet, Galileo is far from being the only GNSS undergoing a noteworthy revolution. Alternatively, the Chinese program BeiDou, still in a developing phase, as well as the American GPS, currently undergoing a modernization of its signals, also knew major progress these last two years. Indeed, 7 new satellites have reached the initial BeiDou constellation, bringing to 20 the number of active satellites. Among them, 5 spacecraft inaugurated the Phase III generation, broadcasting the new B1, B2 and B3 signals. Regarding GPS, the block IIF, made of L5 signal broadcasting satellites, kept expanding but at a less steep rate than BeiDou or Galileo. In this study, we first estimated the individual precisions of each signals broadcast by the aforementioned GNSS. For this purpose, we created two short baselines of approximatively 5 meters between similar type receivers. We combined their measurements to form double differences, leaving in the position equations only multipath and receiver noise. The great expectations regarding Galileo’s quality turned into affirmations as long as we studied this system. As a matter of a fact, the code pseudoranges values of the 4 signals of Galileo we have considered (E1, E5a, E5b, E5a+b) presented outstanding precisions (from 5 to 17 centimetres on code pseudoranges with an elevation mask of 10 degrees) when compared to GPS (from 12 to 20 centimetres on codes pseudoranges) and BeiDou (from 26 to 40 centimetres for codes and for phases) in identical conditions. Even though the precision of Galileo observables is noticeable, the influence of the poor geometry of the satellite constellation degrades in a significant way the resulting precision of the position estimated, no matter the recent increase in the number of satellites. Indeed, in this incomplete constellation, the addition of new satellites results in longer visibility period but not in larger number of satellites observed at a single epoch. Combining Galileo with GPS or BeiDou is a way to solve this issue, as the three systems have been designed to be compatible. Therefore, multi-GNSS relative positioning based on overlapping frequencies should entail better accuracy and reliability in position estimations. However, the differences between satellite systems induce inter-system biases (ISBs) inside the multi-GNSS equations of observation. The overlapping frequencies of these GNSS are the L1 and L5 frequencies of GPS with the E1 and E5a signals of Galileo, respectively. As far as BeiDou is concerned, the B2 signal of emitted by the Phase II BeiDou satellites corresponds to the E5b frequency of Galileo. Regarding the new Phase III satellites, the B2 frequencies will correspond to the Galileo E5a+b signal and B1 of BeiDou will be compatible with E1 of Galileo and GPS. The combined use of these overlapping frequencies in zero baseline double differences (ZB DD) based on a unique pivot satellite is employed to resolve ISBs. This model removes all the satellite- and receiver-dependent error sources by differentiating and the zero baseline configuration allows atmospheric and multipath effects elimination. We conducted this study on the L1/E1, L5/E5a, B1(phase II)/E5b overlapping frequencies. Our receivers were not able to receive the phase III signals of BeiDou satellites. An analysis of the long-term stability of ISBs (GPS- Galileo and Galileo - BeiDou) was conducted on various pairs of receivers over large time spans. The possible influence of temperature variations inside the receivers over ISB values was also investigated. Our study is based on the 6 multi-GNSS receivers (2 Septentrio PolaRx4, 1 Septentrio PolaRxS, 1 Septentrio PolaRx5 and 2 Trimble NetR9) installed on the roof of our building in Liege. The estimated ISBs are then used as corrections in the multi- GNSS observation model and the resulting accuracy of multi-GNSS positioning is compared to GPS, Galileo and BeiDou standalone solutions.

Justification: Lors du traitement par surfactant dit moins invasif (Less invasive surfactant therapy- LIST), le produit est instillé dans la trachée par un cathéter fin alors que l’enfant respire spontanément sous CPAP. Différentes études ont donné des résultats variables mais encourageants. L’objectif de cette méta-analyse est de comparer le devenir respiratoire des prématurés traités par LIST avec celui de ceux traités par administration de surfactant par un tube endotrachéal. Méthodes : les études randomisées contrôlées (ERC) sont recherchées dans les bases de données et dans les références d’articles pertinents. Les devenirs respiratoires (dysplasie broncho-pulmonaire (DBP), décès ou DBP, échec précoce de CPAP, nécessité de ventilation invasive) et les morbidités classiques sont reprises de ces études. Pour chaque morbidité, le risque relatif (RR) des données mutualisées est calculé avec une analyse de Mantel-Haenszel à modèle d’effet aléatoire. Le RR est également calculé pour des sous-groupes établis selon l’intervention contrôle. Résultats : six ERC évaluent le LIST : 4 le comparent à l’INSURE (Intubation-Surfactant-Extubation), et les 2 autres à l’intubation (immédiate ou après maintient en CPAP) avec surfactant. Les méthodes LIST diminuent les risques de DBP (RR= 0,71 (0,52-0,99) ; nombre nécessaire à traiter NNT= 21), et de décès ou DBP (RR= 0,7 (0,58- 0,94) ; NNT= 15). L’échec précoce de CPAP et le recours à la ventilation invasive sont également réduits (RR= 0,67 (0,53-0,84) ; NNT= 8 et RR= 0,69 (0,53- 0,88) ; NNT= 6). Comparé à l’INSURE, le LIST diminue le risque combiné de décès ou DBP (RR= 0,63 (0,44-0,92) ; NNT= 11), et d’échec précoce de CPAP (RR=0,71 (0,53-0,96) ; NNT= 11). Les autres morbidités néonatales classiques sont similaires pour les différents groupes. Conclusions : une stratégie d’administration dite moins invasive de surfactant diminue les risques de morbidité respiratoire à moyen terme (DBP, décès ou DBP) et le recours à la ventilation invasive. Cette approche semble sure mais les données de suivi à long terme sont insuffisantes. [less ▲]

Introduction et objectifs : l’instillation trachéale de surfactant par un cathéter fin (Less invasive surfactant therapy- LIST) chez le prématuré sous CPAP permet de diminuer la morbidité respiratoire. Plusieurs cathéters sont décrits à cette fin : une sonde oro-gastrique insérée avec (LISA-Köln, K) ou sans pince de Maggil (Take Care- Ankara, A), un cathéter veineux de 13 cm (MIST- Hobart, H), un cathéter d’angiographie de 30 cm (Stockholm, S) ou un cathéter ombilical fixé à un stylet d’intubation utilisé localement (Liège, L). L’objectif de l’étude est d’évaluer l’efficacité de ces techniques en prenant l’INSURE (Intubation-Surfactant-Extubation) comme référence. Intervention : 20 néonatologues travaillant dans 4 services ayant des stratégies d’administration du surfactant différentes ont participé. Ils ont simulé ces 6 techniques sur deux têtes d’intubation de difficulté croissante. L’efficacité de l’intervention est évaluée par le taux d’échec et la durée de procédure mesurée sur vidéo. Chaque intervenant apprécie la facilité d’utilisation sur une échelle de 1 à 9 (Difficile> facile). Résultats : Pour le premier modèle, les durées médianes de procédure pour Köln et Ankara sont allongées [K: 21s (IQR 17-24); A: 23s (15-42); H: 10s (8-16); S: 12s (10-22); L (10-20); INSURE: 14s (11-21); p<.0001]. Pour le second modèle, seul Liège permet une durée de procédure similaire à l’INSURE [K: 32s (25-44); A: 39s (27-95); H: 34s (27-46); S: 37s (29-42); L: 24s (15-35); INSURE: 24s (17-32); p<.002]. Les taux d’échec des méthodes LIST sont similaires entre eux (de 3 à 8/ 40 essais), mais supérieurs à celui de l’INSURE (0/40). Köln et Ankara sont considérés comme plus difficiles [scores de facilité : K: 5 (4-6); A: 3 (2-4); H: 6,5 (6-7); S: 7 (4-8); L: 8 (6,5-8); INSURE: 7 (6-8); p<.001]. Conclusions : les cathéters plus rigides sont plus efficaces et perçus comme plus simples d’utilisation. L’insertion d’un cathéter guidé et incurvé pourrait être plus rapide dans les cas difficiles.

Introduction et objectifs: le positionnement adéquat d’un tube endotrachéal (TET) peut être difficile en raison de la marge de manœuvre limitée associée aux faibles distances laryngo-trachéales du prématuré. Les marqueurs distaux censés faciliter l’évaluation de ce positionnement ne sont pas standardisés entre les fabriquants, et le marquage généralement unique par taille de tube ne tient pas compte de la croissance associée à l’âge gestationnel. L’objectif de l’étude est de décrire les distances entre les cordes vocales (CV) et la moitié de la trachée en fonction de l’âge gestationnel et proposer des nouveaux marquages adaptés. Méthodes : la moitié de la longueur de la trachée ajoutée à la hauteur de la lame postérieure du cricoïde permet d’estimer la distance entre les CV et la moitié de la trachée (CV-MiTr). Ces longueurs sont issues à postériori d’une base de données prospective reprenant les distances détaillées du larynx et de la trachée mesurées lors d’autopsies de fœtus et nouveau-nés exempts de malformation des voies respiratoires (Fayoux et coll., Journal of anatomy 2008). Une corrélation est établie avec l’âge gestationnel. Résultats : les données proviennent de 121 patients. Il existe une corrélation linéaire entre la distance CV-MiTr et l’AG (r=0,91; y=2,6043+0,6275x; p<.0001). Des marqueurs d’insertion positionnés à 17,7; 18,9; 20,8; 22,7; 24,6 et 26,4 mm correspondraient à des AG de 24, 26, 29, 32, 35 et 38 semaines respectivement. Ils pourraient être indiqués par des lignes de couleurs contrastées. Conclusion : la relation linéaire entre la distance CV-mi-trachée et l’AG donne l’opportunité de revoir les marqueurs d’insertion des tubes endotrachéaux pour les patients les plus petits. Ces nouveaux marqueurs devraient être comparés cliniquement à ceux actuellement en usage avant d’être généralisés. [less ▲]

We describe a cortical desmoid lesion in a 13-year-old male football player. This case is the typical illustration of symptoms and radiological findings founded in cortical desmoid. Cortical desmoid is benign cortical fibro-osseous lesion that most frequently occurs in the medial supracondylar femur. A traumatic pathogenesis of this lesion is the most probable cause due to higher traction forces at the insertion site of gastrocnemius or the aponeurosis of adductor magnus. It’s usually diagnosed in 10-15-year-old male adolescent who present knee pain, tenderness or swelling. It also can be asymptomatic and incidental finding on radiological exam. Radiologic features depend on the shape and the stage of lesion evolution. It is important to make a correct diagnosis to avoid many additional tests and biopsy, thinking it is a malignant bone tumor. Despite no published therapeutic guideline exists in literature, symptomatic treatment can be considered efficient. [less ▲]

Neurinoma are slow growing encapsulated tumors, coming from Schwann cells. They are a rare cause of low back pain, possibly with a radiating pain in the inferior limb. This case report describes the managing of a patient with right cruralgia without strength lost. The CT- scan had failed to highlight a lesion corresponding to the symptoms of the patient. A MRI was therefore realized, and was able to show a lumbar intradural tumor. The MRI signal of neurinoma is usually typical. However, in this case, the histo-pathological analysis has been necessary to confirm the diagnosis. The patient underwent laminectomy and tumor resection with nearly complete resolution of symptoms, excepting a right perineal hemihypoesthesia, probably corresponding to the location of the concerned nervous root. The MRI is the best method to explore cruralgia or a sciatica not responding to treatment, and without precipitating factor such as disc herniation explaining the symptoms. [less ▲]

3D point clouds describe urban shape at different scales, precisions and resolutions depending on the underlying sensors and acquisition methodology. These factors influence the quality of the data, as well as its representativity. In this paper, we propose a multi-scale workflow to obtain a better description of the captured environment through a multi-scale representative point cloud, presenting an unlimited depth and multisensory data fusion. Our method is shown over a ''smart point cloud'' data structure and based on data fusion principles retaining higher description and precision on overlapping areas. The concept is illustrated through a use case on the castle of Jehay (Belgium), where aerial LiDAR data, terrestrial laser scanner point cloud and photogrammetrybased reconstruction are combined to obtain a multi-scale data structure.

The rural poultry in Algeria is a supplier of popular products. The aims of this study are to characterize local chickens in Kabylie in terms of the livestock practices, management, flock structures, uses, performance and phenotypes. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, and concerns 28 households raising poultry and a morpho - biometric description of 388 (290 females and 98 males) adult local chickens. The farming practices is characterized by a reduction in the time allocated for this activity and to deal with production costs which are aspects of an unproductive extensive livestock system considered as a secondary activity. The body weight is 2.03 ± 0.22 kg and 1.61 ± 0.19 kg respectively in the male and the female. The age at first egg, egg weight, egg production per hen per clutch, number of clutches per year, hatchability and number of chicks weaned are 28.00 ± 3.82 weeks, 49.03 ± 3.66 g, 13.57 ± 1.64, 3.82 ± 1.14, 89.29 ± 9.79% and 7.82 ±1.75 respectively. The comb type is mostly single (89.43%). Skin colours are principally white (39.18%) and yellow (39.43). The comb and wattles are mostly red (93.30). Shanks colours are principally yellow (49.74%) and white (24.23%). The most common plumage colours are salmon (14.43%), white (12.11%), black (17%), grey (9.54%) and gold (9.02%). The genetic improvement of local poultry breeds is also to consider, provided that the suitability of the animal with respect to the context of its breeding is preserved. [less ▲]

Despite increasing use of ANPR cameratechnology, especially in criminal investigations, literature and the experience of the police with whom we worked, seem to show that there is no systematic method to locate as adequately as possible these expensive facilities. Given a set of four categories of robberiesover one year localized within the province of Liège (Belgium), we propose a methodology based on a multi-criteria analysis, making use of density offenses, road density and the distance between the sites of the cameras. Multi-criteria approach can adjust the factorweightings for different types of offenses. In addition, the methodology is iterative, insofar cameras sites are located in successive phases. One result validation criteria is provided in the form of a territorial coverage rate considering the number of selected camera sites and the travel time from each of these sites. [less ▲]

This paper addresses the problem of efficiently operating the storage devices in an electricity microgrid featuring photovoltaic (PV) panels with both short- and long-term storage capacities. The problem of optimally activating the storage devices is formulated as a sequential decision making problem under uncertainty where, at every time-step, the uncertainty comes from the lack of knowledge about future electricity consumption and weather dependent PV production. This paper proposes to address this problem using deep reinforcement learning. To this purpose, a specific deep learning architecture has been designed in order to extract knowledge from past consumption and production time series as well as any available forecasts. The approach is empirically illustrated in the case of a residential customer located in Belgium. [less ▲]

We study the problem of predicting Internet path changes and path performance using traceroute and machine-learning techniques. Path changes are frequently linked to path inflation and performance degradation. Therefore, predicting their occurrence could improve the analysis of path dynamics using traceroute. By relying on neural networks and using empirical distribution based input features, we show that we are able to predict (i) the remaining life time of a path before it actually changes, and (ii) the number of path changes in a certain time slot with relatively high accuracy. We also show that it is possible to predict path performance in terms of latency, opening the door to novel, machine-learning-based approaches for RTT prediction. [less ▲]

In these times of global change, understanding how carbon flows through ecosystems is of primary importance. In coastal Mediterranean regions, Posidonia oceanica meadows produce and store a lot of carbon, but most of it is described as refractory. As a step in the understanding of how organic matter degradation/storage happens in this ecosystem, this study focus on small scale relationships between the microbenthic loop (organic matter, microphytobenthos, bacteria and meiofauna) and environmental parameters (grain size, P. oceanica density, vegetal fibre biomass, pore water nutrient content, sediment total carbon (TC), organic carbon (TOC), nitrogen (TN) and phosphorous (TP) contents, phaeopigments and bacterial production (FDC)). Thus, a 1.25 m x 1.25 m frame was put in a pristine P. oceanica meadow and twelve points were randomly sampled in May 2008 for all the studied parameters. At such a small scale, every component of the microbenthic loop presented a heterogeneity, which was the highest for the microphytobenthos biomass and the lowest for total meiofauna abundance (TMA). No relationship was found between the components of the microbenthic loop but the abundances of Turbellaria and Ciliophora were correlated with total organic matter in the sediment (TOM). None of the environmental parameter was linked with the microphytobenthos biomass, suggesting that the high spatial variability observed did not depend on the measured parameters. Relationships were found between TOM and ammonium, total bacteria abundance and biomass (TBA and TBB) and sediment phaeopigments, TMA and TC, TN and TP. TBB variability was however explained by a combination of FDC and nutrient contents in pore water and sediment. Taking the microbenthic loop as a whole, pore water ammonium and nitrites + nitrates, FDC and phaeopigments were able to explain the observed variability. So, at small scale the variability in the microbenthic loop of a P. oceanica meadow is related with parameters linked with degradation processes and bacteria activities (phaeopigments, FDC, ammonium, nitrites + nitrates), except for meiofauna, which is related with the nutrient content of the sediment, especially TC. Those results underline the importance of the relationship between the microbenthic loop and degradation processes, even at a small scale. [less ▲]

It has recently become possible to monitor patients’ voices outside the speech therapist’s office with a portable, easy-to-use tool: the voice dosimeter. This tool measures voice frequency and sound pressure level, as well as the duration of phonation, during a full day of regular activities. In addition to voice accumulation in an ecological context, the dosimeter used in this study (VoxLog, Sonvox) gives patients feedback on their voice use. In practice, the clinician configures the device so that it provides a vibratory signal in real time when the patient speaks above or below a predetermined frequency or sound pressure threshold. The feedback is intended to make patients aware of inappropriate vocal behavior and encourage them to change it. In this case study, we used biofeedback with the aim of reducing sound pressure level for a teacher suffering from vocal fold nodules. Our goal was to determine whether vibrotactile biofeedback applied in an ecological context for three consecutive weeks could reduce excess sound pressure. The feedback was activated every time the teacher spoke too loudly; its purpose was to help her avoid vocal abuse and (re)learn healthy vocal behaviors. This preliminary study generated encouraging results regarding the use of biofeedback in voice treatment. Nevertheless, it is important to investigate how this tool can best be implemented for patient management in speech language pathology. In addition, the method should be validated with randomized studies using a larger sample. [less ▲]

In this application paper we’ll explain the work flow we use to create immersive visualizations and spatial interaction for geophysical data with a head mounted device (HMD). The data that we analyze consists of two dimensional geographical map data and raw geophysical measurements with devices like seismometers, Electrical Resistivity Tomography (ERT) and seismic tomography profiles as well as other geophysical and geoscientific data. We show the tool chain that we use while explaining the choices that we made along the way. The technical description will be followed by a brief assessment of the added benefit of rendering our data in virtual reality (VR). After the technical description we conclude this paper with some outlook on the (likely) future use of VR in geosciences. [less ▲]

Estimating the stationary background of a video sequence is useful in many applications like surveillance, segmentation, compression, inpainting, privacy protection, and computational photography. To perform this task, we introduce the LaBGen-P method based on the principles of LaBGen and the conclusions drawn in the corresponding paper. It combines a pixel-wise median filter and a pixel selection mechanism based on a motion detection performed by the frame difference algorithm. By working with pixels instead of patches, as originally done in LaBGen, it avoids some discontinuities between different spatial areas and generates better visual results. In this paper, we describe the LaBGen-P method, study its performance on the sequences of the SBMnet dataset, and compare it to that of LaBGen and other methods on the same dataset. Both algorithms emerged as the best ones during the IEEE Scene Background Modeling Contest (SBMC) organized in 2016. However, as there is not yet a good understanding of the recommended metrics, and due to the small amount of video sequences provided with the corresponding ground truth, we have performed a subjective evaluation. More precisely, 35 human experts were asked to compare background images estimated by LaBGen-P and LaBGen, and select the best one. From these experiments, it turns out that the results of LaBGen-P are preferred for about two thirds of the video sequences. Note that we provide an open-source C++ implementation at http://www.telecom.ulg.ac.be/labgen. [less ▲]

Fiber reinforced polymer (FRP) reinforcement in deep beams has been proposed as an alternative to steel reinforcement to increase the durability of members in corrosive environments. Since FRP reinforcement has lower stiffness than steel reinforcement and typically exhibits higher tensile strength, there is a need for new models capable of capturing the effect of these properties on the shear strength of deep beams. This paper proposes such an approach for members without shear reinforcement, which is an extension of a two-parameter kinematic theory (2PKT) for steel-reinforced deep beams. The original approach is modified to account for the effect of large flexural strains on the shear capacity of the critical loading zones in deep beams where the concrete crushes at failure. It is shown that a simple modification based on test data can result in adequate shear strength predictions. It is also shown that the extended 2PKT captures well the effect of reinforcement stiffness, shear-span-to-depth ratio, and section depth on the shear capacity of deep beams with FRP reinforcement.

The assessment of adaptive facades presents a barrier in light of the fact that there is no settled assessment technique se to systematically reach this goal. Many of the available façade performance evaluation systems or frameworks have restricted applicability for such advanced building facades. The complexity of adaptive or dynamic facades evaluation is related to the performance evaluation of façade elements, systems and overall building performance coupled to occupant behavior and occupant satisfaction. In this context, we present\s a case study for an adaptive sunscreens façade and evaluate its performance and occupant behavior. The evaluation focuses mainly on pre and post construction phase of adaptive facades: The design assist phase (including the durability test, visual mockup, onsite mashrabiya mounting and weather stripping), the commissioning phase (field verification and performance testing) and the monitoring phase. The selected project is a 150 meters high twin tower that stands with honey-comb inspired structure and automated dynamic solar screen that responds to the sun’s movement. These solar screens respond dynamically and automatically to the angle of the sun which improves the control over energy consumption, solar radiation and glare with the ability to admit natural light into the building. The paper is part of the research activities of working group 3 of the European COST Action 1403 on “Adaptive Facades “. Different methods were used for evaluation, this include: interviews with the architect and façade engineer and technical control specialist, occupants, reviews of standard and codes, review of energy models and a systematic design process mapping. A documentation of the case study describing the post construction occupant comfort, and façade operation was prepared. This paper’s audience is mainly project managers, architects, building façade engineers together with facility managers concerned with the process of design, construction and operation of adaptive sunscreens facades. The outcome of this study identifies quantifiable performance indicators and effective strategies for the design and performance evaluation of optimal adaptive facades. [less ▲]

BRAIN-TRAINS is a project supported by the Belgian Federal Government that deals with the possible development of rail freight intermodality in Belgium, approaching this transport issue from an interdisciplinary perspective. Life Cycle Assessment (LCA) methodology is used to analyse the sustainability impact of rail freight intermodality. The rail freight system has been divided in three sub-systems: rail transport operation, rail infrastructure and rail transport equipment (locomotives and wagons). First, a SWOT analysis of the intermodal rail freight transport has been performed to identify internal characteristics and possible external trends of the intermodal rail freight transport. The most important elements identified in the SWOT analysis have been selected through a Delphi-technique with the collaboration of a panel of expert. Thirdly, the selected elements have been translated into clear and measurable parameters, defining for every parameter an input value to quantify the scenarios. The parameters are measured in “tonne-kilometre”. Finally, three divergent Belgian scenarios with a time horizon set in 2030 have been built for further analysis. These scenarios are directly linked to the third strategic goal of the European Commission’s White Paper on transport (2011), which aims to shift the 30% of road freight over 300 km to other modes such as rail transport by 2030. As a result, a best, worst and medium case scenarios have been developed, depending on whether the 30% shift has been successfully accomplished, the status quo has been maintained or the goal has not been completely reached by 2030, respectively. The direct transport emissions and energy consumption during the rail transport activity have been determined using the LCA methodology. These LCA results have been used to improve the accuracy of existing commercial databases as Ecoinvent for the Belgian situation. [less ▲]

Green Building movement has grown in Jordan for the last 10 year for environmental and financial reasons directly related to energy consumption and cost. Despite the few success stories, green design and green buildings are not yet the norm in the building sector in the country. One main concern for design engineers as well as investors and building owners is the extra cost green building will bring compared to traditional one. This assumption is wrong since a building cost should be analyzed through its life cycle, which not only include design and construction but also operation and maintenance costs as well. Since issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, Jordan opened a new era in the RE and EE, a changing point directly related to this law is the ability to sell electricity production to electricity companies and not only being consumers. The building sector is a direct winner if designers and engineers make right decisions. An ambitious but possible goal is to design and build Net Zero Buildings, which are buildings that produce energy as much as they consume. The aim of this paper is to provide real life cost-effective building strategies and design scenarios that will lead to a successful near Zero Energy Building in Jordan. The paper will use a representative residential apartment in the city of Amman (135- 155 m2) as the base case for the study. The design will be upgraded to include main green building strategies recommended for the climatic zone, provide loads for required systems, and test them all against performance and cost. Design scenarios will be tested and refined tell reach the best design formula that will be both functional and cost effective. The paper will provide a list of recommendations for best economically feasible design solutions and system selections that can lead to a near Zero Energy Building in Jordan for residential apartments.

Mitral and aortic regurgitations (MR and AR) are common in horses. Unlike mild valvular regurgitations, long-term prognosis of moderate or severe MR and AR is suspected to be guarded since they might induce congestive heart failure (CHF). The aim of this study is to perform a long-term follow-up of horses with moderate or severe MR and/or AR to confirm this prognosis. Firstly medical files of horses with moderate or severe MR and/or AR that had a follow-up, were retrospectively reviewed over a 15-years period (2000-2015). Clinical and echocardiographic data of 25 horses with moderate or severe MR (16/25) or AR (8/25) or both (1/25) were considered. All horses had undergone 2 or more echocardiographic exams 6 months to 10 years apart. Eight horses developed CHF (4 MR and 4 AR) and all died/were euthanized. Diastolic left ventricular internal diameter, left atrial diameter and pulmonary artery diameter were/became above reference values in 17/25 horses but no significant difference was observed between the first and the follow-up measurements (Student's t-test, p<0.05). Secondly follow-up data of additional horses with moderate or severe MR was collected by telephone survey. Owners of 27 horses agreed to answer the survey 1 to 6 years after diagnosis. Ten horses with CHF had died, 3/27 had developed CHF, 10/27 had remained clinically stable and 4/27 had died of non-cardiac causes. Results of this study confirm that moderate or severe MR and AR carry a guarded to poor long-term prognosis as 40% (21/52) of the studied horses developed CHF. [less ▲]

Traceroute is the most widely used Internet path analysis tool today to study the topology of the Internet and to diagnose routing failures as well as poor performance events. A major limitation of traceroute when the destination is not controllable by the user is its inability to measure reverse paths, i.e., the path from any given destination back to the source. This is a major drawback for ISPs, who need to understand the performance of the Internet paths connecting popular services (e.g., YouTube and Facebook) to their customers. Even if public servers and distributed measurement platforms can provide partial reverse path visibility through ad-hoc measurements, there is still a need for a structured approach capable of analyzing the performance of Internet paths connecting any pair of nodes (servers, routers, hosts, etc.). While the problem of reverse traceroute has been addressed in the past, proposed techniques rely on IP address spoofing – which might lead to security concerns, and assume the availability of certain route-tracking options –, which might not be available. In this paper, we introduce and evaluate DisNETPerf, a new tool which provides exactly the same type of information as traceroute, but for paths connecting arbitrarily selected nodes. DisNETPerf works by firstly locating probes (i.e., measurement points) that are the closest to a given target node, using them to perform traceroute measurements from the target point-of-view to a given destination for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path (from server to users) can be measured with very high accuracy in certain scenarios. We also analyze relevant characteristics of Internet paths and distributed measurement platforms, which reinforce the applicability and relevance of DisNETPerf in current Internet. [less ▲]

Belgium has fifteen structures included in the list of large dams of the International Committee on Large Dams. Six are managed by Engie Company, the other nine are owned by the Walloon regional public authority. The Belgian legislator has never enacted specific rules for large dams. However, managers have always been concerned with this issue. They developed procedures and methods that were subject to exchanges of experience with their counterparts, in particular through the Belgian Committee on Large Dams. In this ongoing research of security, the impact of multiple failure scenarios (dam break, quick emptying …) on the people and the environment downstream of dams is a particular focal point. An impact study has been conducted for the main plants. This study is based on a deterministic numerical method. The methodology, the assumptions regarding the failure mode or emptying and the lessons learned from the analyses are presented. These results are an important step in the assessment and the management of risks. Indeed, regulations were recently enacted for the management and the coordination of any activity likely to seriously impact public safety during crisis periods. These rules apply therefore for large dams. In this context, managers have established an emergency plan for each structure. This paper provides a broad overview on the issues of the evaluation and the management of dysfunction risks of Belgian dams, as well as on approaches and collaborations initiated between the private managers and public authority.

Land-use change models are used to explore the dynamics and drivers of land-use/landcover change and to inform policies affecting such change. A broad array of applications and modeling methods are available and each type has certain advantages and disadvantages depending on the objective of the research. This work presents an approach combining cellular automata (CA) model and supported vector machine (SVM) and binary logistic regression model (Logit) for simulating urban expansion in Wallonia (Belgium). This article emphasizes the interest in comparing combining CA with conventional Logit versus combining CA with SVM method as a base of CA model transition rule. Relative operating characteristic (ROC) and spatial matrices are used to validate the model. Model validation shows that the allocation performance of CA-SVM outperformed CALogit approach. [less ▲]

Nel 2011 l’UNESCO ha adottato la Raccomandazione sul Paesaggio Storico Urbano che mira al riconoscimento e all'identificazione della stratificazione e dell'interconnessione dei valori - naturali e culturali, materiali e immateriali, internazionali e locali – riscontrabili in qualsiasi città storica, concepita come un “patrimonio vivente” delle comunità. In tale visione il patrimonio culturale urbano è un elemento riconosciuto non solo dagli esperti, ma dalle intere società che ne valutano gli elementi identitari mirando a conservarli per le generazioni future. La Raccomandazione, in particolare, sostiene che per l'interpretazione e la conservazione del patrimonio culturale si può beneficiare di metodi di valutazione tradizionali e di metodi innovativi basati su dati geo-localizzati e sui dati digitali dei social media, come tweets geo-localizzati, impronte digitali e foto su Flickr. Il presente contributo illustra una metodologia basata sull’analisi delle immagini su Flickr. Dai risultati ottenuti si è evinto che proprio l’indagine dei social media può contribuire ad una comprensione significativa dei valori culturali del contesto urbano, fornendo così la possibilità di una migliore integrazione dei valori socio-culturali riconosciuti dalla collettività nei processi di conservazione e di pianificazione urbana.

Il presente contributo intende approfondire i caratteri iconografici delle realtà paesaggistiche urbane e naturali rappresentate nei disegni di alcune personalità della cultura belga di fine Ottocento. In particolare le immagini presenti nei tre volumi di Emile Bruylant, (La Belgique illustrée, editi nel 1892) – hanno registrato quei caratteri urbani e naturali che il Belgio vedeva dissolversi in favore di un preteso sviluppo politico ed economico del periodo di Leopoldo II. Nell’ultimo decennio del XIX secolo una grande opera di sensibilizzazione nei confronti della tutela del paesaggio belga urbano e naturale fu portata avanti in Belgio da numerosi artisti, i quali furono tra i primi a nutrire spiccata sensibilità verso i temi della conservazione e delle testimonianze storiche. Il contributo intende dunque analizzare il legame tra le immagini riportate nei volumi e lo sviluppo di talune posizioni conservative che nell’ambito belga è possibile riscontrare in alcune figure, tra cui quella di Charles Buls) e nell’ azione della Société Nationale pour la protection des sites et des monuments.

This communication is part of a larger research project that aims to develop and test a model about the collaboration practices of female entrepreneurs, through identifying antecedents and consequences for entrepreneurial success. The objective of our communication is to explore collaborative entrepreneurship, an emerging topic in the literature, from the perspective of female entrepreneurs in Luxembourg. We share here the first insights brought by our exploratory study on this relatively underinvestigated topic, in particular in the women’s entrepreneurship field. Through the analysis of an in-depth longitudinal case study with two women entrepreneurs who created and developed a business collaboration, completed by a set of qualitative interviews with other women entrepreneurs working in collaboration, we are able to propose a first understanding of this phenomenon and to establish the bases for a theoretical model.

Rab guanine nucleotide exchange factor (GEF)1 (Rabgef1) is a guanine nucleotide exchange factor for the endocytic GTPase Rab5, and also exhibits E3 ubiquitin ligase activity in vitro. In vivo functions of Rabgef1 remain largely unknown, but Rabgef1 is critical for health, as globally Rabgef1-deficient mice exhibit perinatal mortality and those surviving to adulthood spontaneously develop severe skin inflammation.This protein is highly expressed in murine intestinal epithelial cells (IECs). Objective: The aim of this study is to clarify the role of Rabgef1 in murine IECs Materials and methods: We performed conditional deletion of Rabgef1 using the cre-lox system to obtain mice lacking Rabgef1 specifically in IECs (Rabgef1IEC-KO). Results: Rabgef1IEC-KO mice did not develop spontaneous intestinal abnormalities but showed an increased susceptibility to inflammation in dextran sodium sulfate (DSS)-induced col itis model. Indeed, compared to littermate controls, mice lacking Rabgef1 in IECs exhibited shorter and highly inflamed colons and higher inflammatory scores in histopathological examination of colons, suggesting that Rabgef1 expression regulates IEC function and is critical in limiting DSS induced inflammation and damage. In addition, we also showed that mRNA expression of pro-inflammatory cytokines, such as Il1b and Tnfa, was upregulated in IECs isolated from Rabgef1IEC-KO mice compared to the ones isolated from littermate controls. Conclusion: Taken together, these results suggest that Rabgef1 acts as a regulator of intestinal homeostasis, and that dysregulated Rabgef1 expression could contribute to intestinal barrier dysfunction in inflammatory conditions of the gut.

Organic Rankine Cycle (ORC) technology has demonstrated to be a suitable tool for recovering waste heat at low temperatures. The fluctuating nature of the waste heat source (varying temperature and mass flow) makes of waste heat recovery applications a challenging task. In this contribution Model Predictive Control (MPC) and more classical PID-like controllers are investigated, where special attention is paid to the analysis of the control performance for heat source profiles coming from different applications. A dynamic model of a real regenerative ORC unit equipped with a single screw expander developed in the Modelica language is used to test and compare the PID and MPC based control strategies. Results show that for low amplitude variations PID and MPC can perform equally good, but in case of large variations MPC is a more effective control strategy as it allows a safer and more efficient operation, operating close to the boundary conditions where production is maximized.

Characterization of NEAs provides important inputs to models for atmospheric entry, risk assessment and mitigation. Diameter is a key parameter because diameter translates to kinetic energy in atmospheric entry. Diameters can be derived from the absolute magnitude, H(PA=0deg), and from thermal modeling of observed IR fluxes. For both methods, the albedo (pv) is important - high pv surfaces have cooler temperatures, larger diameters for a given Hmag, and shallower phase curves (larger slope parameter G). Thermal model parameters are coupled, however, so that a higher thermal inertia also results in a cooler surface temperature. Multiple parameters contribute to constraining the diameter.Observations made at multiple observing geometries can contribute to understanding the relationships between and potentially breaking some of the degeneracies between parameters. We present data and analyses on NEA 3691 Bede with the aim of best constraining the diameter and pv from a combination of thermal modeling and light curve analyses. We employ our UKIRT+Michelle mid-IR photometric observations of 3691 Bede's thermal emission at 2 phase angles (27&43 deg 2015-03-19 & 04-13), in addition to WISE data (33deg 2010-05-27, Mainzer+2011).Observing geometries differ by solar phase angles and by moderate changes in heliocentric distance (e.g., further distances produce somewhat cooler surface temperatures). With the NEATM model and for a constant IR beaming parameter (eta=constant), there is a family of solutions for (diameter, pv, G, eta) where G is the slope parameter from the H-G Relation. NEATM models employing Pravec+2012's choice of G=0.43, produce D=1.8 km and pv≈0.4, given that G=0.43 is assumed from studies of main belt asteroids (Warner+2009). We present an analysis of the light curve of 3691 Bede to constrain G from observations. We also investigate fitting thermophysical models (TPM, Rozitis+11) to constrain the coupled parameters of thermal inertia (Gamma) and surface roughness, which in turn affect diameter and pv. Surface composition can be related to pv. This study focuses on understanding and characterizing the dependency of parameters with the aim of constraining diameter, pv and thermal inertia for 3691 Bede. [less ▲]

(6) Hebe is a large main-belt asteroid, accounting for about half a percent of the mass of the asteroid belt. Its spectral characteristics and close proximity to dynamical resonances within the main-belt (the 3:1 Kirkwood gap and the nu6 resonance) make it a probable parent body of the H-chondrites and IIE iron meteorites found on Earth.We present new AO images of Hebe obtained with the high-contrast imager SPHERE (Beuzit et al. 2008) as part of the science verification of the instrument. Hebe was observed close to its opposition date and throughout its rotation in order to derive its 3-D shape, and to allow a study of its surface craters. Our observations reveal impact zones that witness a severe collisional disruption for this asteroid. When combined to previous AO images and available lightcurves (both from the literature and from recent optical observations by our team), these new observations allow us to derive a reliable shape model using our KOALA algorithm (Carry et al. 2010). We further derive an estimate of Hebe's density based on its known astrometric mass. [less ▲]

We analyze two multi-chord stellar occultations by the Trans-Neptunian Object (TNO) 2003 AZ84 observed on February 3, 2012 and November 15, 2014.They provide different elliptical limb fits that are consistent to within their respective error bars, but could also suggest a possible precession of the object (assumed here to be a Maclaurin spheroid). The derived equatorial radius and oblateness are R[SUB]e[/SUB] = 393 ± 7 km and ɛ = 0.057 in 2014 and R[SUB]e[/SUB] = 414 ± 13 km and ɛ = 0.165 in 2012, respectively. Those results are consistent with single-chord events observed in January 2011 and December 2013. The figures above provide geometric visual albedos of p[SUB]V(2014)[/SUB] = 0.112 ± 0.008 and p[SUB]V(2012)[/SUB] = 0.114 ± 0.020. Using the Maclaurin assumption, combined with possible rotational periods of 6.67 h and 10.56 h, we estimate density upper limits of 1.89 ± 0.16g/cm[SUP]3[/SUP] and 0.77 ± 0.07g/cm[SUP]3[/SUP] for the two dates, respectively.The 2014 event provides (for the first time during a TNO occultation) a grazing chord with a gradual disappearance of the star behind 2003[SUB]AZ[/SUB]84's limb that lasts for more than 10 seconds. We rule out the possibility of a localized dust concentration as it would imply very high optical depth for that cloud. We favor a local topographic feature (chasm) with minimum width and depth of 22 ± 2.5 km and 7 ± 2.0 km, respectively. Features with similar depths are in fact observed on Pluto's main satellite, Charon, which has a radius of about 605 km, comparable to that of 2003[SUB]AZ[/SUB]84. [less ▲]

We report the discovery of three short-period Earth-sized planets transiting a nearby ultracool dwarf star using data collected by the Liège TRAPPIST telescope, located in la Silla (Chile). TRAPPIST-1 is an isolated M8.0±0.5-type dwarf star at a distance of 12.0±0.4 parsecs as measured by its trigonometric parallax, with an age constrained to be > 500 Myr, and with a luminosity, mass, and radius of 0.05%, 8% and 11.5% those of the Sun, respectively. The small size of the host star, only slightly larger than Jupiter, translates into Earth-like radii for the three discovered planets, as deduced from their transit depths. The inner two planets receive four and two times the irradiation of Earth, respectively, placing them close to the inner edge of the habitable zone of the star. Several orbits remain possible for the third planet based on our current data. The infrared brightness of the host star combined with its Jupiter-like size offer the possibility of thoroughly characterizing the components of this nearby planetary system. [less ▲]

In northern winter, a broad distribution of ice aerosols appears in the north polar atmosphere of Mars, commonly referred to as the North Polar Hood (NPH). The NPH is thought to be formed as a result of condensation from lowered temperatures associated with both seasonal and diurnal variations in solar heating. The spatial extent and density of the NPH is highly variable, with a maximum latitudinal extent spanning 30-80°N, and a maximum density at 10-30 km altitude.The NPH has been extensively observed by both ground-based telescopes and instruments in orbit around Mars. However, the majority of these observations are nadir-pointing. This observation geometry has two significant limitations. Firstly, they poorly probe the vertical structure of the NPH. Secondly, column densities are determined by monitoring the intensity of various spectral features associated with the ice composing the NPH, against a strong background with similar features from the frost that has condensed on the surface in the winter season, resulting in low sensitivities. Limb observations removes both limitations, allowing us to study the vertical distribution of the aerosols that make up the NPH at high sensitivities.We present new limb observations of the NPH by IUVS (Imaging Ultraviolet Spectrograph) on the MAVEN (Mars Atmospheric and Volatile Evolution) spacecraft. These observations represent the first ultraviolet limb observations of the NPH, opening a new window for understanding the structure and composition of the NPH. The observations are also of the twilight limb, with sunlight being scattered from the dayside into the nightside over large solar zenith angles. This illumination geometry allows us to avoid the high dayside intensities that would drown out the signal from the thinner sections of the NPH. We determine the latitudinal extent of the NPH to be 30-60°N. We also find that an exponential altitude distribution of aerosols is able to reproduce the observed intensities, with a scale height similar to the atmospheric scale height. Finally, we observe an almost mutual exclusion of the NPH and nitric oxide nightglow emissions, an effect of the global circulation that drive both phenomena. [less ▲]

The Imaging Ultraviolet Spectrograph (IUVS) on NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission observed the Martian upper atmosphere in late 2015 (Ls ~ 70) and early 2016 (Ls ~ 150). Although designed to measure the dayglow between 90-200 km IUVS also scans the limb down to 60 km, where solar scattered light dominates the mid-ultraviolet (MUV) signal. Occasionally, this MUV light shows enhanced scattering between 60-90 km indicating the presence of aerosols in the mesosphere. We quantify the solar scattering for each daylight scan obtained between October and December, 2015 and between April and June, 2016. We then identify over 100 scans of enhanced scattering between 60-90 km and assemble them both geographically and diurnally. The geographical distribution of the enhancements in 2015 is preferentially located near the equator, consistent with previous observations of mesospheric clouds for this part of the season. A wave three pattern in equatorial cloud occurrence suggests forcing from a non-migrating tide, possibly linked to the longitudinal variation of Mars surface topography. At the same time, there are indications of a diurnal variation such that the clouds seen in 2015 and 2016 are preferentially observed in the early morning, between 0600-0900 local solar time. This suggests an important role for a migrating temperature tide controlling the formation of Martian mesospheric clouds. [less ▲]

Planetary upper atmosphere energetics is mainly governed by absorption of solar extreme ultraviolet (EUV) radiation. Understanding the response of planetary upper atmosphere to the daily, long and short term variation in solar flux is very important to quantify energy budget of upper atmosphere. We report a comprehensive study of Mars dayglow observations made by the IUVS instrument aboard the MAVEN spacecraft, focusing on upper atmospheric response to solar EUV flux. Our analysis shows both short and long term effect of solar EUV flux on Martian thermospheric temperature. We find a significant drop (> 100 K) in thermospheric temperature between Ls = 218° and Ls = 140°, attributed primarily to the decrease in solar activity and increase in heliocentric distance. IUVS has observed response of Martian thermosphere to the 27-day solar flux variation due to solar rotation.We also report effect of two solar flare events (19 Oct. 2014 and 24 March 2015) on Martian dayglow observations. IUVS observed about ~25% increase in observed brightness of major ultraviolet dayglow emissions below 120 km, where most of the high energy photons (< 10 nm) deposit their energy. The results presented in this talk will help us better understand the role of EUV flux in total heat budget of Martian thermosphere. [less ▲]

H escape oxidizes and dessicates the Mars atmosphere and surface, providing a key control on the present-day chemistry and long-term evolution of the planet. Recently, large variations in the escape rate of H as a function of season have been reported by several studies, making continued observation of the variation a high priority. We present escape rates derived from Mars Atmosphere and Volatile EvolutioN (MAVEN) mission Imaging UltraViolet Spectrograph (IUVS) observations of the extended atmosphere of Mars at H Lyman alpha (121.6 nm), which must be interpreted with a coupled density/radiative transfer model owing to the optically thick nature of the emission and the small fraction of H present in the corona on escaping trajectories. We recover densities, temperatures, and escape rates under the assumption of spherical symmetry for multiple periods across MAVEN's mission so far, beginning in December 2014 (escape rates ~4e8/cm2/s). We describe the observed variation and compare it with previously observed seasonal variation in retrieved H escape rates, providing a necessary input for future photochemical modeling studies and estimates of water loss from Mars over its history.

The broad capabilities of the Imaging UltraViolet Spectrograph on the MAVEN mission are enabling new science ranging from Mars' lower atmosphere up though the escaping corona. After two years in Mars orbit, the instrument has yielded insights on the Mars dayglow, season cycles, nightglow, aurora, meteor showers, clouds, solar-planetary interactions and atmospheric escape. In this presentation we will highlight several new discoveries. First, IUVS has observed a third type of aurora not previously seen at Mars, indicative of a new kind of solar-planet interaction for non-magnetized planets. Second, spatial mapping of nitric oxide nightglow reveals regions of atmospheric downwelling necessitating substantial changes to global atmospheric circulation models. Finally, a new high-spatial-resolution UV imaging mode allows unprecedented determinations of Mars' low-altitude ozone, as well as detection of clouds from nadir to limb. [less ▲]

The enhanced ratio of D/H in the martian atmosphere has long been interpreted to provide evidence for the historic loss rate of water into space, with the enhancement resulting from the mass ratio of the species. Understanding the dependence of the enrichment of D on the loss rate of water requires that one understand the controlling factors, including all sources of exospheric hydrogen and the present-day transport of D and H into the upper atmosphere. Toward this end the MAVEN mission has included an echelle channel in the IUVS instrument that resolves the D and H Lyman alpha emissions produced by resonant scattering of bright solar emission. In this mode it has now been possible to measure the upper atmospheric D and H abundances over most of a martian year. The results are surprising, with larger than expected changes in the D and H abundances and a changing ratio of D/H with a strong seasonal dependence. This talk will present the D and H data to date (Mars will be near perihelion by the time of the DPS meeting) and discuss the interpretation of the large changes that have been observed. [less ▲]

The Imaging Ultraviolet Spectrograph (IUVS) instrument on the Mars Atmosphere and Volatile EvolutionN (MAVEN) mission is designed to measure radiances of several of the most abundant species present in Mars' atmosphere. Many spectral features are associated with ions; one of the most prominent spectral features in the mid-ultraviolet region is the CO[SUB]2[/SUB][SUP]+[/SUP] Ultraviolet Doublet (UVD) at 289 nm. However this emission, and many others, results from several radiative processes, some of which originate from the ionization process and is therefore not diagnostic of the ion densities. Several other emissions are diagnostic of ion densities, especially at high altitudes, and therefore lend themselves to density retrievals based on inclusion of all radiative processes. The most promising of these is the Fox-Duffendack-Barker (FDB) (3,0) band at 314 nm, near the long-wavelength limit of the IUVS instrument. We report on a new process for performing density retrievals of CO[SUB]2[/SUB][SUP]+[/SUP] with particular attention to the credibility of high-altitude signal in the FDB bands as well as the associated uncertainties. We also investigate the feasibility of C[SUP]+[/SUP] and other ion density retrievals. [less ▲]

BACKGROUND Classification criteria are recommended for diseases that lack highly specific biomarkers in order to improve homogeneity in clinical research. Since imaging evidence of lumbar spinal stenosis (LSS) or lumbar disc herniations (LDH) may not be associated with symptoms, clinical classification criteria based upon patient symptoms and physical examination findings are required. This study sought to develop a set of criteria identifying patients with neurogenic claudication (NC) caused by LSS and patient with radicular pain (RP) caused by LDH. This abstract reports the results concerning NC caused by LSS. METHODS Phase 1: Nineteen spine specialists (clinicians and researchers) from 8 countries participated in a Delphi process, using an internet program, to rank symptoms and signs which suggest LSS as the cause of NC or DH as the cause of RP. Phase 2: Nineteen different spine specialists (surgeons and non-surgeons) from 5 countries recruited patients during office visits and classify them with a high degree of confidence as having with either: 1) NC caused by LSS 2) RP caused by LDH or 3) non-specific low back pain (NSLBP) with non-specific leg pain radiation. Patients completed survey items and specialists documented examination signs. Signs and symptoms present in ≥ 10 patients were analyzed by using Generalized Estimating Equations (GEE). Patients with NC caused by LSS or NSLBP served as controls. Items with p<0.1 in univariate analysis were entered in the multivariate analysis. A score to predict NC caused by LSS was developed based on the coefficient of the GEE, and used to obtain a ROC curve and the associated area under the curve (AUC). RESULTS A list of 46 clinical signs and 28 patient-reported symptoms were selected by the group of spine specialists during the 1st phase. For the 2nd phase, 209 patients with high confidence in the diagnosis were included 63 NC caused by LSS, 89 RP caused by DH, and 57 NSLBP with non-specific leg pain radiation. Items which predicted NC with a p-value <0.1 included age >60, bilateral leg pain, leg pain relieved by sitting, leg pain decreased by leaning or flexing, positive30 seconds extension test, negative straight leg raise test. The score had an AUC of 0.91, and the cutoff to obtain a specificity of 92.1% resulted in a sensitivity of 80.0%. CONCLUSION An international collaboration of surgeon and non-surgeon spine specialists produced a set of diagnostic criteria with high specificity and sensitivity for identifying patients with NC caused by LSS. Using this set could improve the quality of basic science and clinical research in this field by improving homogeneity within groups of patients. [less ▲]

BACKGROUND Classification criteria are recommended for diseases that lack highly specific biomarkers in order to improve homogeneity in clinical research. Since imaging evidence of lumbar spinal stenosis (LSS) or lumbar disc herniations (LDH) may not be associated with symptoms, clinical classification criteria based upon patient symptoms and physical examination findings are required. This study sought to develop a set of criteria identifying patients with neurogenic claudication (NC) caused by LSS and patient with radicular pain (RP) caused by LDH. This abstract reports the results concerning NC caused by LSS. METHODS Phase 1: Nineteen spine specialists (clinicians and researchers) from 8 countries participated in a Delphi process, using an internet program, to rank symptoms and signs which suggest LSS as the cause of NC or DH as the cause of RP. Phase 2: Nineteen different spine specialists (surgeons and non-surgeons) from 5 countries recruited patients during office visits and classify them with a high degree of confidence as having with either: 1) NC caused by LSS 2) RP caused by LDH or 3) non-specific low back pain (NSLBP) with non-specific leg pain radiation. Patients completed survey items and specialists documented examination signs. Signs and symptoms present in ≥ 10 patients were analyzed by using Generalized Estimating Equations (GEE). Patients with NC caused by LSS or NSLBP served as controls. Items with p<0.1 in univariate analysis were entered in the multivariate analysis. A score to predict NC caused by LSS was developed based on the coefficient of the GEE, and used to obtain a ROC curve and the associated area under the curve (AUC). RESULTS A list of 46 clinical signs and 28 patient-reported symptoms were selected by the group of spine specialists during the 1st phase. For the 2nd phase, 209 patients with high confidence in the diagnosis were included 63 NC caused by LSS, 89 RP caused by DH, and 57 NSLBP with non-specific leg pain radiation. Items which predicted NC with a p-value <0.1 included age >60, bilateral leg pain, leg pain relieved by sitting, leg pain decreased by leaning or flexing, positive30 seconds extension test, negative straight leg raise test. The score had an AUC of 0.91, and the cutoff to obtain a specificity of 92.1% resulted in a sensitivity of 80.0%. CONCLUSION An international collaboration of surgeon and non-surgeon spine specialists produced a set of diagnostic criteria with high specificity and sensitivity for identifying patients with NC caused by LSS. Using this set could improve the quality of basic science and clinical research in this field by improving homogeneity within groups of patients. [less ▲]

This paper deals with an innovative methodology dedicated to the study of historical mortars. Gathering macroscopic observation, petrography in thin sections, chemical analyses as well as physical and mechanical data namely obtained with non destructive technologies developed for the petroleum industry, it allows cross-interpretation that can effectively contribute to archaeological research through correlations with the age, the function, the technology and the provenance of each mortar sample collected on a studied site. Following a synthetic description of the proposed approach, a practical application is illustrated on the site of a mediaeval fortress located in Belgium. [less ▲]

The successful implementation of a high-efficient latent heat storage system necessitates an appropriate experimental approach to investigate and quantify the variations of the Phase Change Material (PCM) thermal properties caused by its aging, as well as its potential demixing induced by cyclic freezing and melting. In this paper, we present a concept for the PCM characterization. The proposed method is relatively simple to be implemented. It consists of a cyclic cooling and melting of the PCM sample placed into a tube and monitoring its temperature evolution with a set of temperature sensors. In our work, the temperature evolution of the sample, as well as its sensitivity to the thermal parameters have been numerically investigated using the COMSOL Multiphysics® software. [less ▲]

Ce travail entend examiner les rapports entre les représentations photographiques des corps des scientifiques dans la revue de vulgarisation savante La Recherche, tels les portraits, les scènes de travail collectif en laboratoire etc., et les conceptions de la science qui en sont valorisées. L’étude des relations entre les photographies et les textes qui les accompagnent ont ainsi pour objectif de déployer une réflexion non seulement sur les différents types de commensurabilité entre le langage verbal et le langage visuel mais aussi sur le fait que le langage visuel est à même de forger de manière tout à fait autonome des valeurs identitaires et des formes de vie identifiables via l’analyse sémiotique. Notre exploration se développera en deux volets : le premier vise à esquisser la méthodologie de la sémiotique visuelle pour pouvoir introduire les niveaux pertinents de l’analyse sémiotique, le deuxième consiste à analyser un corpus constitué de textes tirés de quelques numéros de la revue La Recherche en en distinguant les différents genres discursifs (entretien, présentation de travaux en cours, etc.) et les différents types de cadrage et de mise en scène photographique afin d’expliquer comment ils se combinent avec les prises de position épistémologiques valorisées.

In our text we examine image visualizations generated from big collections of archived images produced by Lev Manovich and his team in the field of Cultural Analytics. Our aim is to examine how these image visualizations function as analysis-images from two correlated perspectives of one semiotic approach: 1. Enunciation. What point of view is conveyed by the image visualizations about the computer-manipulated archive images? 2. Rhetorical/mereological composition: What is the mereological relation between the final visualization and the multitude of images that it contains, filters, or manipulates? [less ▲]

Les études cliniques sur les couronnes et les bridges en zircone Y-TZP ont indiqué des taux d'échecs élevés liés aux fractures cohésives de la céramique d’émaillage (chipping). Pour remédier à ce problème, les fabricants commercialisent des couronnes monolithiques, entièrement en zircone, qui sont simplement maquillées en surface. Cependant, ces restaurations sont suspectées d’être plus sensibles à la fatigue hydrique de la zircone, problème qui aboutit à une baisse des propriétés mécaniques et qui fut à l’origine de nombreux échecs avec les prothèses de hanche. En effet, l’absence de céramique d’émaillage sur les couronnes monolithiques les rend plus vulnérables vis à vis du milieu oral ; de plus, certaines zircones de haute translucidité, spécifiquement développées pour cette indication, sont réputées plus sensibles en raison d’une plus grande métastabilité. Enfin, le recul clinique sur ces restaurations est très faible et leur comportement général, notamment en terme d’usure des dents antagonistes, a besoin d’être étudié. Une étude clinique est actuellement menée à l’Université de Liège, en collaboration avec l’Université Paris Descartes, afin d’évaluer le comportement clinique de la zircone non émaillée en milieu buccal, et particulièrement la fatigue hydrique, sur une période de 5 ans. Les résultats à très court terme (6 mois) mettent en évidence le bon comportement clinique des restaurations monolithiques en zircone, avec cependant une usure rapide de la glaçure, ce qui pourrait promouvoir la fatigue hydrique. Les zones de transformation cristalline détectées soulignent la nécessité d’une cuisson de régénération de la zircone suite aux ajustements occlusaux par fraisage. [less ▲]
