L’alexithymie, souvent considérée comme un trait de personnalité, serait-elle sensible aux traitements psychothérapeutiques dispensés en hôpital de jour ? Quelles en seraient les variables prédictives ? Notre recherche a porté sur un échantillon de 192 participants hospitalisés, majoritairement représenté par des patients présentant des troubles de l’humeur (64,6%). Plusieurs variables ont été prises en considération : le sexe, l’âge, la durée d’hospitalisation (M séjour = 6 semaines), la médication, les dix échelles cliniques de base du « Minnesota Multiphasic Personality Inventory-2 » (MMPI-2), l’indice de négativité au traitement du MMPI-2 (échelle TRT) et le support social perçu (PSS) mesuré par la « Multidimensional Scale of Perceived Social Support » (MSPSS). Les impacts positifs du support social perçu et les impacts négatifs de la non-adhésion au traitement se sont révélés être des prédicteurs particulièrement significatifs de l’alexithymie. [less ▲]

Almost a century ago, Presburger showed that the first order theory of the natural numbers with addition is decidable. Following the work of B\"uchi in 1960, this result still holds when adding a function $V_k$ to the structure, where $V_k(n)$ is the largest power of $k\ge 2$ diving $n$. In particular, this leads to a logical characterization of the $k$-automatic sequences. During the last few years, many applications of this result have been considered in combinatorics on words, mostly by J. Shallit and his coauthors. In this talk, we will present this theorem of B\"uchi where decidability relies on finite automata. Then we will review some results about automatic sequences or morphic words that can be proved automatically (i.e., the proof is carried on by an algorithm). Finally, we will sketch the limitation of this technique. With a single line formula, one can prove automatically that the Thue-Morse word has no overlap but, hopefully, not all the combinatorial properties of morphic words can be derived in this way. We will not assume any background in combinatorics on words from the audience. [less ▲]

Introduction For years, bad news delivery’s impact on patients or their relatives, as well as physicians’ stress has been a major concern. Based on studies claiming the efficacy of training courses to help physicians delivering such news, many protocols, like SPIKES, BREAKS or SHARE, have emerged worldwide. However, training to such protocol might be time-consuming and not suitable with junior doctors or trainees’ turnover. We hypothesised that a standardized 5-hours training program could improve bad news delivery practice. Participants and methods This preliminary study was conducted in the ED of a tertiary care academic hospital accounting for 90000 ED census per year, 16 attending physicians, 10 junior residents, and 5 trainees per month. Data were collected between November 2015 and April 2016. The study included 3 phases over 4 weeks. Video recorded single role-playing sessions happened the 1st (T1) and the 4th (T3) weeks. A 3-hour theory lesson happened the second week (T2), introducing the basics of therapeutic communication and delivering bad news. Each role-playing session lasted almost 1 hour (10 minutes briefing and medical case reading, 10 minutes role-plays and 40 minutes group debriefing). Bad news delivery performance was evaluated by a 14-points retrospective assessment tool (1). We collected data about the status and impact of a stressful event at 3-days using the French version of the IES-R scale (2). We applied Student t-tests for statistical analysis. Results 14 volunteers (10 trainees and 4 junior emergency physicians) were included in the study. On average, bad-news delivery process took 9’45’’ at T1 and 10’20’’ at T3. From T1 to T3, bad-news delivery performance increased significantly for both junior emergency physicians and trainees (p=0.0003 and p=0.0006, respectively). Further analysis revealed that most relevant increases involved the “situation” (p<0.001), “presentation” (p=0.009), “knowledge” (p=0.037), “emotions” (p=0.01) and “summary” (p=0.001) steps. We also found a significant decrease of the impact of bad-news delivery on trainee physicians’ stress (p=0.006). Discussion and conclusion These preliminary results indicate some potential for this new standardized course of bad news delivery. Apart from allowing physicians increase their communications skills, we believe that this simple 5-hour simulation-training program could alleviate physicians’ stress when they happen to break bad news.

Il y a peu, la voie de production de la toxine a été découverte : celle-ci met en oeuvre un double mécanisme de régulation génétique. Cependant, certains aspects de la perception de son hôte par le pathogène sont toujours inconnus. Dans ce poster, nous proposons plusieurs hypothèses pour expliquer comment quelques éléments subtiles peuvent être à l'origine de ce mécanisme de pathogénicité. [less ▲]

We introduce a generalization of Pascal triangle based on binomial coefficients of finite words.

Besides their entertainment value, serious games can have beneficial therapeutic effects for elderly people that improve their health and well-being. Games are likely to be accepted by elderly persons who have enjoyed games their lives, and because there are more and more of such elderly, it is important to investigate games as a therapeutic device. This research reviewed the literature focusing on the effects of games on elderly persons in three main types of effects: physical, cognitive, and social effects. The majority of reviewed papers focused on physical and cognitive effects, and were published in recent years, which emphasizes the relative novelty of this topic and suggests that future research will need to address social impact as well. In addition, while many papers claimed positive impacts as a result of using games, our review found that more attention should be given to research designs. [less ▲]

An anomaly in the Congress of Vienna: Neutral Moresnet or how to rethink the political and linguistic boundaries. Neutral-Moresnet was a 3.4 km² neutral territory near Aachen. Its history is the result of a misunderstanding. In Article 25 of the Vienna Final Act, Moresnet is annexed to Prussia, but in Article 66 this province is placed under Dutch sovereignty. In the site of "Vieille-Montagne” an important zinc mine is discovered. They decided to establish co-sovereignty. From then on, two commissioners oversee the area. Over time, Moresnet developed a national folklore, especially with the process of Nation-State at the end of the 19th century. This triangle is seen by foreign observers as the smallest country in the world and even as an "imaginary country" (vampires, new Eldorado). Some Esperantists hoped to make Moresnet the country of international languages ​​because in this tiny territory German, French and dialects are spoken. Moresnet rethinks the concept of border. After the Treaty of Versailles in 1919, this small state belongs to Belgium. [less ▲]

Introduction The development of motor skills competencies is critical during childhood should be considered as the central learning outcome in physical education. Assessing motor competencies of the children make sense for teachers, trainers and researchers. The MOBAK-1 testing battery has been recently developed with the aim of assessing a wide panel of motor skills in relationship with locomotion and object-control abilities (1). This battery is complete and easy to use but present a scoring system that is only based on the success or the failure of the task. The aim of the study was to collect descriptive data from Belgian children with MOBAK-1, and to do a critical analysis of the scoring system through the analysis of the failure reasons in the tests. Methods The MOBAK-1 testing battery (1) was addressed to 166 primary school pupils (7.2±0.6 YO) coming from the French speaking part of Belgium. For each test, children received a score from 0 to 2, according to the number of success and fails in the task. Additionally, the evaluator took notes of the failure reasons when it occurs. Results Results from our subjects were in accordance with a previous study (1) for all tests except rolling and jumping tasks. The analysis of the failure reasons revealed that some criteria were too severe as some children failed while they were almost able to do the test correctly. This appeared especially in the rolling and jumping tests where the score did not really reflect the level of the children. Conclusion MOBACK-1 testing battery was successful to assess children motor skills for 6 out of 8 tests. Critical analysis of children failures in the tests revealed that some criteria seemed to be severe. Scoring system should be improved in order to inform about the children level in each test.

A method is presented to model the incompressible, attached, unsteady lift and moment acting on a thin three-dimensional wing in the time domain. The model is based on the combination of Wagner theory and lifting line theory trough the unsteady Kutta-Joukowsky theorem. The result is a set of closed form linear ordinary di erential equations that can be solved analytically or using a Runge-Kutta-Fehlberg algorithm. The method is validated against numerical predictions from an unsteady Vortex Lattice method for rectangular and tapered wings undergoing step or oscillatory changes in plunge or pitch. As the aerodynamic loads are written in state space form in the proposed method, they can be easily included in aeroelastic and flight dynamic calculations. [less ▲]

Laser cladding is a metal deposition technique used to fabricate or repair components. In the present work Ti-6Al-4V deposits with a variable thickness are studied to assess the use of laser cladding as a repair technology [1]. Solidification following melting and partial remelting of pre-existing layers is coupled with heat treatment of the solidified material due to the repeated heating and cooling cycles during building. The effect of the building strategy on the metallurgical characteristics of the material for a decreasing track length (DTL) or a constant track length (CTL) strategy is analyzed. Depending on the possible heat accumulation, the nature of the phases are determined by metallography and hardness maps of the deposits. Optical Microscopy (OM), Stereo Microscopy (SM), and Scanning Electron Microscopy (SEM) were used in order to study the microstructure. The generation of the microstructure results from the material thermal history. This one is computed by Finite Element Method and a careful analysis establishes the link between the phase state and the detailed thermal history. [less ▲]

Introduction: Mesenchymal stromal cell (MSC) infusion could be a mean to establish donor-specific immunological tolerance in solid organ recipients. The aim of this phase 2 study was test the hypothesis of possible induction of operative tolerance by third-party MSC in liver transplant (LT) recipients. Methods: 10 stable and low-risk LT recipients under standard immunosup- pression (Tac-MMF- low dose steroids) received 1.5–3 9 106/kg third-party MSCs on post-operative day 3 ` 2. By protocol, progressive weaning of immunosuppression was attempted in patients who did not develop rejection and had normal graft function and month-6 graft biopsy. Tacrolimus was progressively tapered from day 180 to be discontinued by day 270. After day- 270 graft biopsy, MMF was progressively tapered and definitely discontinued by day 365 in the absence of rejection. Results: One patient from the MSC group was excluded from immunosup- pression withdrawal attempt due to HCC recurrence, and the 9 others met the necessary criteria. In one patient, tacrolimus and MMF withdrawal was performed without rejection. In two patients, MMF monotherapy was achieved at month 9, but graft rejection occurred during MMF withdrawal and was successfully treated by tacrolimus reintroduction. In 6 patients, the transam- inases significantly increased during tacrolimus withdrawal. In these cases, withdrawal was cancelled and liver tests normalised after increase of the tacrolimus dose. No graft was lost due to the withdrawal attempt. Conclusion: A single post transplant MSC injection is not sufficient to induce operative tolerance after LT. [less ▲]

Jointed interfaces are sources of the greatest amount of uncertainty in the dynamics of a structural assembly. In practice, jointed connections introduce nonlinearity into a system, which is often manifested as a softening response in frequency response, exhibiting amplitude dependent damping and stiffness. Additionally, standard joints are highly susceptible to unrepeatability and variability that make meaningful prediction of the performance of a system prohibitively difficult. This high degree of uncertainty in joint structure predictions is partly due to the physical design of the interface. This paper experimentally assesses the influence of the interface geometry on both the nonlinear and uncertain aspects of jointed connections. The considered structure is the Brake-Reuß beam, which possesses a lap joint with three bolted connections, and can exhibit several different interface configurations. Five configurations with different contact areas are tested, identified, and compared, namely joints with complete contact in the interface, contact only under the pressure cones, contact under an area twice that of the pressure cones, contact only away from the pressure cones and Hertzian contact. The contact only under the pressure cone and Hertzian contact are found to behave linearly in the range of excitation used in this work. The contact area twice that of the pressure cone behaves between the complete contact and contact only under the pressure cone cases. [less ▲]

Introduction: Donation after circulatory death (DCD) has been proposed to partially overcome the organ donor shortage. DCD-LT remains controversial, with reported increased risk of graft loss and retransplantation. The authors retrospectively reviewed a single centre experience with controlled DCD-LT in a 14-year period. Patients and Methods: 125 DCD-LT were consecutively performed between 2003 and 2016. All donation and procurement procedures were performed as controlled DCD in operative rooms. Data are presented as median (ranges). Median donor age was 56 years (16–84). Most grafts were flushed with HTK solution in the first part of experience, and more recently with IGL1. Allocation was centre-based. Median follow-up was 52 (1–164) months. No patient was lost to follow-up. Results: Median total DCD warm ischemia was 19 min (9–39). Median cold ischemia was 238 min (105–576). Patient survivals were 90.2%, 77.5% and 74.5 % at 1.3 and 5 years, respectively. Graft survivals were 87.7%, 76.3% and 73.2% at 1.3 and 5 years, respectively. Biliary complications included anas- tomotic strictures and extrahepatic main bile duct ischemic obstruction, that were managed either by endoscopy or hepatico-jejunostomy. No PNF was observed in this series and one graft was lost due to ischemic cholangiopathy. Discussion: In this series, DCD LT appears to provide results similar to classical LT. Short cold ischemia and recipient selection with low MELD score may be the keys to good results in DCD LT, in terms of graft survival and avoidance of ischemic cholangiopathy. [less ▲]

One of the major challenges in nonlinear system identification is the selection of appropriate mathematical functions to model the observed nonlinearities. In this context, piecewise polynomials, or splines, offer a simple and flexible representation basis requiring limited prior knowledge. The generally-adopted discretization for splines consists in an even distribution of their control points, termed knots. While this may prove successful for simple nonlinearities, a more advanced strategy is needed for nonlinear restoring forces with strong local variations. The present paper specifically introduces a two-step methodology to select automatically the location of the knots. It proposes to derive an initial model, using nonlinear subspace identification, and incorporating cubic spline basis functions with fixed and equally-spaced abscissas. In a second step, the location of the knots is optimized iteratively by minimizing a least-squares cost function. A single-degree-of-freedom system with a discontinuous stiffness characteristic is considered as a case study. [less ▲]

Introduction Since decades in Wallonia (French speaking part of Belgium), athletics competitions for children are miniaturized versions of adults’ competitions. Despite the fact that it has been pointed out that such kind of approach, based on performance, is not appropriated for motor learning and could result in an increased rate of dropout (1), no change has occurred since years. The International Association of Athletic Federation has developed and promoted a more appropriate model of competition for children under 10 years old: ‘Kids’Athletics’ (KA)(2). While this model is well known, it has not been selected by the Wallonian federation as the gold standard yet . This study aimed to analyze the perceived interest of a group of experts about KA, and to identify the strategies that could be considered for KA implementation in Wallonia. Methods Semi-structured interviews were conducted with 14 athletics or marketing experts (demographic presentation; knowledge about KA and personal experience with KA ; opinion about KA model in comparison with the traditional one, and ; strategies that could be helpful to implement KA in Wallonia). Results Findings showed that 12 experts knew the KA concept while 9 have experimented it in their own club. None mentioned an official competition between clubs. A list of KA’s advantages and disadvantages has been identified (organization, children needs, and development). All experts considered that KA was more adapted to children than traditional competition. Based on subjects’ proposals, a progressive strategy for KA implementation is suggested. It includes the support of the federation and recommends to start with the more convinced clubs. Conclusion This study confirms that KA should be implemented in Wallonia. In order to optimize the chances of success, it would be appropriate to multiply actions, taking into account the potential barriers identified by the experts.

From December 2006 through to the end of 2015, over 150,000 people were intentionally killed in Mexico. Accordingly, from 2006 to the present day, the number of murders and enforced disappearances related to organised crime in Mexico has skyrocketed. The United Nations Office of Drugs and Crime has indicated that from 2007 to 2010, Mexico was the country with the highest rate of increase in intentional homicides. The so-called “war” against organized crime has created a context of increasing insecurity and escalating violence, impunity and corruption across the entire country. Against the backdrop of the security crisis, members of Mexican society have organised national and transnational movements to denounce the government. For instance, some observers have hypothesised that the case of the 43 missing students of Ayotzinapa in September 2014 raised awareness amongst the Mexican population and bolstered their political engagement in both national territory and abroad. Mexicans living in the United States, Spain, France, Belgium, Australia, New Zealand and other places around the world have engaged politically to demonstrate their support for the victims and denounce the incapacity of the current State to govern. This paper looks at the political transnational movements organised by Mexican migrants living specifically in Brussels and Paris to answer the following question: Is political transnationalism a tool for peacebuilding for the Mexican on going security crisis? This paper evaluates how has transnational political activism changed the dynamics of the on-going conflict. [less ▲]

Le glioblastome multiforme (GBM) est un des cancers les plus fatal, avec une médiane de survie de 14 mois après traitement. Il est donc nécessaire de développer de nouvelles thérapies plus efficaces. La fonctionnalisation en surface de nanocapsules lipidiques (LNC) avec le peptide NFL-TBS.40-63 (NFL) a déjà montré une amélioration de leur internalisation dans des cellules de glioblastome murin. Le but de cette étude a été d’évaluer l’impact de la concentration en NFL présente en surface des LNC sur l’internalisation de ces dernières dans des cellules humaines de GBM U87MG. De plus, le mécanisme d’internalisation LNC-NFL a été étudié. Une sonde fluorescente (DiA) a été encapsulé dans : des LNC (F1), des LNC avec 0.86 % et 2.58 % (w/w) de NFL adsorbé à la surface (F2 et F3 respectivement). Des analyses par cytométrie en flux (FACS) ont révélé une internalisation cellulaire de F3 plus importante de 46.4 et 6.8 fois après 30 min, de 21.6 et 6.1 fois après 1 heure, de 31.5 et 1.6 fois après 6 heures et de 7.3 et 1.1 fois après 24 heures, comparés à F1 et F2 respectivement. L’internalisation de F3 dans les cellules U87MG s’est révélée être énergie-dépendant, avec comme mécanisme principal la macropinocytose. Les cinétiques de désorption du peptides (obtenues par dialyse de F3 dans du Tris-Buffer pH 7.4 à 37°C suivi par une HPLC analytique) ont montré que 66 % de NFL restaient à la surface des LNC après 6h de dialyse, montrant une désorption lente. De plus, les trois formulations ont montré une faible activation du complément. Du fait d’une internalisation significativement plus prononcée et rapide, F3 semble être prometteur pour améliorer l’efficacité des thérapies antiGBM. De plus, la lente désorption du NFL de la surface des LNC et la faible consommation du complément font de F3 une thérapie ciblé prometteuse contre le GBM. [less ▲]

Nappe oscillation may affect a variety of free overflow hydraulic structures operating at low heads such as crest gates and various types of weirs. This phenomenon produces oscillations in the thin nappe cascading downstream of the control structure. These oscillations can result in a high noise levels that may affect people and structures located nearby. With long linear and thin overtopping walls, piano key weirs might be subject to strong nappe oscillation risks, as a few documented cases with labyrinth weirs. However, the specific geometric features of piano key weirs, such as the outlet ramps or the limited width of the inlet apex, could perhaps prevent the development of nappe oscillation. In this paper, a prototype-scale linear weir is operated to assess the risk of nappe oscillations on a piano key weir like configuration (sidewall). In particular, the effect of the weir width and inclined apron is analyzed. The experimental results show that nappe oscillation development should not occur on piano key weir, contrary to what might be observed on a labyrinth weir with the same crest. [less ▲]

Peat based growing media are not sustainable and not easily colonized by biocontrol organisms. Plant fibers may allow for partially replacing peat in growing media and they may have the potential to carry biocontrol organisms. However, they may also carry plant pathogens and they may vary in their degree of biodegradability and their interaction with N, and thus they may affect the quality of growing media. Several defiberization techniques were tested for flax shives, miscanthus and reed straw for their ability to (1) kill plant pathogens present on the plant fibers, (2) reduce the N-fixation risk of the fibers and (3) provide fibers serving as carrier of biocontrol fungi. Flax shives obtained from various sources were colonized by viable microsclerotia of the plant pathogen Verticillium dahliae. However, when sufficiently high temperatures were reached during defiberization, this technique killed the plant pathogen on the shives, allowing the use of defiberized flax shives in growing media. Untreated flax shives, miscanthus or reed straw were characterized by high N immobilization. Using these plant fibers as peat replacement in growing media may thus reduce N availability for plants. According to the incubation trials results, extruding, retruding and applying disc refining significantly reduced the N immobilization for miscanthus straw without affecting the pH of the fiber, while steam explosion significantly reduced the pH and resulted in higher N immobilisation. Extruding and retruding the flas shives increased the N fixation. Defiberized pure miscanthus or reed straw and flax shives were easily colonized by fungal biocontrol strains, e.g. Trichoderma spp. . The effect of inoculation with fungi or acidification on N fixation was tested for extruded miscanthus fibers. Inoculation with shiitake (Lentinula edodes) or Agrocybe aegerita, i.e., 2 fungi without biocontrol properties was effective in reducing the N immobilization only in a specific pH range and at high colonization degree and/or for fungi with fast colonization, but never increased the N fixation when successfully inoculated. Inoculation of extruded Miscanthus fibers with different strains of biocontrol fungi did not increase nor decrease the N immobilization. Reducing the pH of the fibers between pH 2.5 and 4.7 was effective in reducing the microbial activity and the N fixation. Finetuning the conditions is necessary when applying acidification or inoculation for reducing the N fixation in plant fibers. N immobilization in growing media is related to biological activity. We compared 3 methods to determine the microbial biomass on plant fibers in growing media incubated with mineral N fertilizers, i.e., fumigation-extraction, plfa and Q-PCR, and used water-extractable C to measure the easily available C in the plant fibers. The extrusion of miscanthus straw with or without inoculation of a biocontrol organism reduced the N immobilization when compared with the pure fiber. In case of flax shives, defiberization of plant fibers kills plant pathogens that may be present on the fibers when sufficiently high temperatures are reached during defiberization. Inoculation of plant fibers with biocontrol fungi may be beneficial for increasing the disease resistance in growing media, and we found that inoculation of extruded Miscanthus fibers with biocontrol fungi did not increase nor decrease the N immobilization.

Introduction and Aims: Estrogens have a positive impact on the auditory function. Indeed, estradiol (E2) treatment in animals protects against acoustic trauma and aminoglycoside toxicity and its depletion can contribute to age-related hearing loss. However, estradiol is not suitable in clinical practice, given the increased risk of cancer and thromboembolic events. There is a need to find new treatments that present a higher benefit/risk ratio. In this work, we studied a new natural estrogen derivative, estetrol (E4), that was shown to act as a Selective Estrogen Receptor Modulator (SERM). Estetrol is thus able to display estrogen-like as well as antiestrogen activity depending on the target tissue. Interestingly, E4 allows the prevention of menopause symptoms such as osteoporosis or hot flushes through an agonistic action, whereas it exerts anti-estrogenic effects on the mammary gland. These preclinical data suggest that E4 presents a safer profile than E2. Material and Methods: To investigate whether this molecule presents otoprotective actions, we exposed P2 cultured organs of Corti to gentamicin, with or without estetrol (E4). After 48 hours of culture, hair cell survival was evaluated following anti-myosin VII Immunohistochemistry. We next moved on to in vivo studies using young zebrafish larvae (5dpf), since they constitute a highly effective model to determine the potential ototoxicity of drugs and to screen for candidates of hair cell protective agents. We monitored the survival of hair cells within neuromasts following chronic or acute exposure to gentamicin. Results: In cochlear culture, gentamicin-induced hair cell loss was significantly reduced by E4. Interestingly, the toxicity of aminoglycoside was also reduced in vivo upon treatment of zebrafish larvae with E4. Conclusion: The survival rate of hair cells was increased in the presence of estetrol both in vitro and in vivo indicating that estetrol constitutes an interesting protective drug against hearing loss.

Shrimp value chain in Vietnam functions with a large number of farmers. The stay in the weakest position in the chain due to their small individual scale with an average land of about 0.5 ha/farm, and low skills (Ho, 2012). As a leader and holding the strongest power in the shrimp value chain, the processors determine shrimp prices and set up requirements of shrimp quality and size in the market though quality control has not been completely implemented due to the limitations of financial capital, knowledge, awareness, as well as the quality of raw material supplied by collectors and farmers. In order to help the shrimp sector to work more efficiently, the Vietnamese government brought together shrimp farmers and plant processors through a farming contract. Two years after this application, the contract farming model failed due to the floor price mechanism, risk sharing, small scale of the model while there are excess suppliers in the market, administrative misconception and inefficient public management. As a result, farmers still stay at the weakest position and the shrimp sector could not improve its product safety to adapt to the requirement of import markets. The study results recommend necessarily a planning and projection of shrimp production zones, re-organizing shrimp farmers into legal teams or groups or coopératives to increase the size of the existing shrimp cultivation units in Vietnam.

The well-known de Vries duality, established by H. de Vries in 1962, states that the category of compact Hausdorff spaces is dually equivalent to that of de Vries algebras. The notion of Boolean contact algebra (BCA) was developed independently in the context of region-based theory of space. Düntsch and Winter established a representation theorem for BCAs, showing that every BCA is isomorphic to a dense subalgebra of the regular closed sets of a T_1 weakly regular space. It appears that BCAs are a direct generalization of de Vries algebras, and that the representation theorem for complete BCAs generalizes de Vries duality for objects. During a conference, Vakarelov raised the question of dualizing morphisms. We answer this question using concepts similar to those of modal logic's neighborhood semantics. [less ▲]

Although a key-concept in Art historical discourse and reasoning, creativity has almost always been avoided as an issue in the discussion of Ancient Egyptian Art, as if the notion was simply irrelevant in such a context. This surprising phenomenon has clearly deep roots in the history of the western vision of Ancient Egyptian Art (and civilization). Nonetheless, the investigation of some (actually quite rare) cases of true copies in Ancient Egyptian Art reveals that creativity operated within a process of reinterpretation of previous works and their tradition, a process that can be best described and analyzed, it seems, with the help of the conceptual frame of intericonicity (or interpictoriality). The paper also aims to defend the use of this notional tool in the analysis of Ancient Egyptian Art by attempting to define how creativity was conceived in Ancient Egyptian textual claims for innovation and originality [less ▲]

Les eaux souterraines des aquifères de socle cristallin de la partie centrale du Bénin (Département des Collines) présentent des concentrations élevées en fluorure, allant jusqu'à 7 mg/L alors que la norme recommandée par l'OMS est de 1.5 mg/L. La consommation de ces eaux à fortes teneurs en fluorure impacte la santé humaine. La population de la région est effectivement largement affectée par la fluorose dentaire. Les investigations hydrogéochimiques révèlent que l’origine de ces teneurs anormales est géogénique avec une forte contribution des minéraux ferromagnésiens, principalement la biotite. Ce travail se propose de réaliser une double cartographie à l'échelle du département des Collines: (i) une carte de l'estimation des teneurs en fluorure dans les eaux souterraines par krigeage ordinaire et (ii) une carte de la probabilité d'excéder la valeur guide de l’OMS (1.5 mg/L) en fluorure dans les eaux par krigeage d'indicatrices. Outre la cartographie en elle-même, l'analyse de la structure spatiale des données (teneurs en fluorure des eaux souterraines) à travers le calcul des variogrammes montre qu'il existe un lien fort entre celles-ci et les structures géologiques dominantes, confirmant l'origine géogénique du fluorure. Ces informations cartographiques serviront de support à la décision pour les décideurs et les gestionnaires de la ressource quant au choix judicieux des zones de captage d'eau potable pour minimiser/éviter les risques de fortes teneurs en fluorure.

From literature, it is clear that the discussion about the potential benefits and drawbacks of autonomous vehicles is not finished. In order to provide insight into this discussion, this paper investigates different attitudes with respect to different key factors for the deployment of system of autonomous taxis. To this end, a stated adaptation experiment was carried out in Belgium in March 2016. To investigate which factors influence the variables of interest, i.e. (i) the number of minutes one is prepared to wait before an autonomous taxi picks up the person, (ii) the ownership of a private car when autonomous taxis are available, (iii) the willigness to share an autonomous taxi, (iv) the permittance for the autonomous vehicle to take a detour when it is beneficial for the society, and (v) the willigness to share your private agenda to ensure a timely autonomous taxi, different regression models are constructed. The results show that the considered explanatory factors only capture a small part of the variability five variables of interest. This is as signal that market segmentation might be very challenging. Besides, this is an indication that a broader range of factors should be included such as life-style factors and psychological constructs. Finally, this acknowledges the need for some skepticism with regard to the potential benefits of autonomous vehicles. The results are interesting for providing realistic boundaries and cross-classification in further simulation studies that look at the benefits of autonomous vehicles. [less ▲]

Chez les patients atteints de maladie d’Alzheimer (MA), on observe dès les stades débutants d’une part un phénomène d’anosognosie, qui peut être considéré comme une altération de la conscience de soi, et d’autre part un dysfonctionnement des processus de monitoring mnésique [1]. En outre, l’interaction entre le soi et la mémoire (conférant un bénéfice mnésique pour les informations associées à soi), apparaît significativement altérée dans la MA. Dans la présente étude, nous avons examiné les relations entre l’anosognosie et le monitoring lors de la récupération en mémoire d’informations expérimentalement associées à soi. Nous avons évalué les processus de monitoring lors de la récupération en mémoire à l’aide d’une tâche expérimentale de 32 paires visage-prénom, ainsi que l’anosognosie à l’aide du questionnaire d’anosognosie dans la démence (AQD, [2]) chez 20 patients MA et 20 personnes âgées contrôles (AC). Durant la phase d’encodage, les paires visage-prénom ont été présentées aux participants soit comme des personnes faisant partie de leur famille (soi) soit comme des personnes faisant partie de la famille de l’expérimentateur (autrui). Ensuite, nous avons évalué les jugements de « sentiment de savoir » (FOK), les performances de rappel et de reconnaissance, ainsi que les jugements de confiance (JOC) des participants pour le nom de chaque personne lorsque son visage était présenté. Nos résultats ont confirmé l’altération de la conscience de soi (c’est-à-dire l’anosognosie mesurée par l’AQD), l’altération du bénéfice mnésique pour les informations associées à soi, ainsi que l’altération des processus de monitoring lors de la récupération en mémoire (FOK et JOC) chez les patients MA. Néanmoins, une modification de l’interaction entre le soi et les processus de monitoring chez ces patients a été observée uniquement au niveau des sentiments de confiance pour des souvenirs erronés. Nous avons également observé que l’anosognosie des troubles comportementaux était significativement corrélée à la proportion de sentiments de confiance pour des reconnaissances erronées sur les items associés à soi. En conclusion, notre étude suggère que l’altération de la conscience des troubles comportementaux chez les patients MA pourrait être liée à un déficit de monitoring des souvenirs liés à soi. C’est-à-dire que la conscience altérée du dysfonctionnement au quotidien pourrait s’appuyer sur des souvenirs personnels déformés. [less ▲]

Preliminary study of data blending of surface current for Sunda Strait-Indonesia has been done using the analysis scheme of the Ensemble Transform Kalman Filter (ETKF). The method is utilized to combine radial velocity from HF Radar and u and v component of velocity from Global Copernicus - Marine environment monitoring service (CMEMS) model. The initial ensemble is based on the time variability of the CMEMS model result. Data tested are from 2 CODAR Seasonde radar sites in Sunda Strait and 2 dates such as 09 September 2013 and 08 February 2016 at 12.00 UTC. The radial HF Radar data has a hourly temporal resolution, 20-60 km of spatial range, 3 km of range resolution, 5 degree of angular resolution and spatial resolution and 11.5-14 MHz of frequency range. The u and v component of the model velocity represents a daily mean with 1/12 degree spatial resolution. The radial data from one HF radar site is analyzed and the result compared to the equivalent radial velocity from CMEMS for the second HF radar site. Error checking is calculated by root mean squared error (RMSE). Calculation of ensemble analysis and ensemble mean is using Sangoma software package. The tested R which represents observation error covariance matrix, is a diagonal matrix with diagonal elements equal 0.05, 0.5 or 1.0 m 2 /s 2 . The initial ensemble members comes from a model simulation spanning a month (September 2013 or February 2016), one year (2013) or 4 years (2013-2016). The spatial distribution of the radial current are analyzed and the RMSE values obtained from independent HF radar station are optimized. It was verified that the analysis reproduces well the structure included in the analyzed HF radar data. More importantly, the analysis was also improved relative to the second independent HF radar site. RMSE of the improved analysis is better than first HF Radar site Analysis. The best result of the blending exercise was obtained for observation error variance equal to 0.05 m 2 /s 2 . This study is still preliminary step, but it gives promising result for bigger size of data, combining other model and further development [less ▲]
