Integrated optimization techniques for mechatronic systems aim at designing simultaneously the trajectory, the control system and the mechanical structure in order to minimize a performance index. The key advantage of such an integrated approach is the capability to search in a wide design space, to account for many dynamic couplings in an early design stage and to avoid simplifying assumptions which would induce a suboptimal design. This work considers that technique for robotic manipulators with flexible links. It is known that a exible multibody system is often non-minimum phase, here, no restriction is imposed to avoid it. This allows a free choice of the optimization process to select a lighter weight controlled system. Furthermore, the amplitudes of the non-actuated degrees-of-freedom should be reduced in order to limit bodies deformation. The mechanical model is derived using a nonlinear finite element method, which is a useful approach to represent systems with elastic bodies. An optimal control problem is considered to perform that integrated analysis and its time dicretization relies the direct transcription method. [less ▲]

Two-dimensional speckle tracking (2DST) is a non-invasive technique used in many species to evaluate global and regional left ventricular (LV) function; however it received little attention in the bovine species. The aim of this study was to assess the feasibility and reliability of 2DST for the evaluation of circumferential and radial LV wall motions in calves. Fourteen Holstein black calves (age: 62 11.6 days; body weight: 75.25 5.4 kg) were used in this observational study. Right parasternal short axis views at the level of the papillary muscles were recorded and subsequently analysed by 2DST for global and regional radial and circumferential strains and strain rates, radial displacement, rotation and rotation rate. Echocardiographic examinations were performed in unsedated, standing calves by two different observers to evaluate intra- and interobserver repeatability and variability. 2DST was feasible in all calves but 2 were excluded from analyses (ventricular septum defect and resting heart rate above 120 bpm, respectively). Automated tracking was better in systole than in diastole. Intraobserver repeatability was good to moderate for most systolic global and segmental peak values. Systolic peak values for radial strain and strain rate were more repeatable than for circumferential strain, circumferential train rate and diastolic measurements. Variability of the interobserver measurements was greater than the intraobserver measurements. Two-dimensional speckle tracking is feasible in calves and as in other species systolic radial function can be more reliably evaluated than circumferential and diastolic function. [less ▲]

L’aménagement transsexuel comme solution à l’adolescence La transsexualité est souvent banalisée par les médias, séduits par l’idée facile à vendre d’une âme sexuée, donc du drame de la possible inadéquation entre le sexe psychique et le sexe corporel. L’observation clinique rigoureuse de son élaboration plaide cependant pour une architecture complexe, résultant d’une dynamique subtile entre le psychisme, l’histoire et l’environnement. En effet, dans l’analyse d’un cas clinique, nous constatons que, face au risque de l’effondrement identitaire d’une structure fragile le Moi tente de se renforcer par l’organisation de mécanismes de défense qui élabore une nouvelle identité étayée sur un physique transité vers l’autre sexe. Si l’on analyse les interactions précoces sous l’angle de la formation de l’identité sexuelle, le noyau « genré » du Moi peut subir une double attaque, par manque d’identification au même et par attaque mortifère du différent. Le Moi se trouve ainsi délié et persécuté par des objets partiels ou peu introjectés. A l’adolescence, moment potentiellement traumatique de la sexuation, le jeune se trouve confronté à l’interrogation sur son identité sexuelle, et lorsque le noyau « genré » s’est précisément trouvé fragilisé, l’angoisse surgit, avec le risque d’une bascule psychotique. Dans ces cas extrêmes, la recherche d’une nouvelle enveloppe, remodelage de la peau, permet de contenir l’éclosion du courant psychotique grâce à la disponibilité permanente de l’incorporation du différent, identification certes coûteuse en ressources mais peut-être, à même d’éviter l’effondrement narcissique complet.

Doxycycline (DOXY) is associated with left ventricular (LV) dysfunction in calves in accidental overdose but not in experimental models when evaluated with classical and Doppler echocardiography. Two-dimensional-speckle tracking (2DST) is used to evaluate LV dysfunction in numerous species but not in cattle. The aim of this study was to evaluate the cardiotoxic effects of an experimental overdose of DOXY using 2DST in calves. Ten healthy male Holstein calves. Group 1: 5 calves (mean age 58.0 +/- 16.3 days; mean body weight 72.2 +/- 13.0 kg) received 25 mg/kg of DOXY orally for 5 days. Group 2: 5 calves (mean age 56.4 +/- 15.7 days; mean body weight 73.4 +/- 7.0 kg) received a placebo. Electrocardiography (ECG) and 2DST echocardiography were performed at day 0 and day 8. ECG tracings were analysed for occurrence of arrhythmias. 2DST measurements included global and segmental, peak values for radial and circumferential strains (SR, SC), strain rates (SrR, SrC), rotation (Rot), rotation rates (RotR) and radial displacement (DR). All calves completed the study. ECG recordings were unremarkable in both groups. Heart rate was neither significantly different between groups nor before and after treatment. LV systolic function was affected in calves receiving an overdose of DOXY as shown by a significant decrease of segmental SR (P < 0.05), SC (P < 0.05) and DR (P < 0.05) in treated calves compared to the placebo group in several segments. The SrC in early diastole was also significantly decreased in 1 segment (<0.05). In calves, DOXY overdose induces a LV dysfunction in systole, and to a lesser extent, in diastole. A better comprehension of the pathophysiology involved in the DOXY overdose will help in the treatment of accidental cases. [less ▲]

In this work we study which are the minimal anomaly-free chiral fermion sets, beyond the standard model, that lead to vector-like particles with respect to SU(3) and U(1)em after symmetry breaking. We focus on fermion multiplets with SU(3) and SU(2) dimensions less than or equal to 10 and 5, respectively. Furthermore, we study whether the addition of such chiral fermions allows for gauge coupling unification, at some high scale compatible with proton decay limits. [less ▲]

Passive houses have, at design stage, to fulfill a number of performance criteria. One of them imposes the normalized theoretical heat demand to be limited to 15 kWh/m², year. In operation, it is very difficult to check, from simple observations or measurements, the real performance of such a house: different energy vectors may be used to meet the space heating as well as the domestic hot water demand, a storage tank may be used and fed by different energy sources (heat pump, direct electricity, solar thermal). The problem is still more complicated if the house is equipped with PV panels which naturally decrease the apparent electrical consumption. In the frame of the IEA Annex 58 project, a passive house was the object of a detailed analysis aiming at estimating the different terms of the energy balance. Some terms were results of direct in situ measurements and unmeasured terms such as solar and internal gains were estimated by dynamic simulation. The combination of measurements and simulation results allowed a reconstruction of a robust energy balance. The paper provides a detailed description of the approach and of each term of the rebuilt energy balance. [less ▲]

This paper deals with the initial development of a methodology for controlling real-life, multi-body dynamical systems in the presence of uncertainties in our knowledge of their exact physical nature as well as uncertainties in the ‘given’ forces acting on them. We assume that both these uncertainties can be time-varying, yet bounded. The methodology is developed in two steps. In the first step an exact control of the so-called nominal system—our best assessment of the real-life physical system and the forces acting on it—is developed. This control is inspired by results from analytical dynamics and involves no linearizations and/or approximations of the nonlinear, nonautonomous system. It also minimizes a suitable norm of the trajectory errors at each instant of time. In the second step, a continuous controller using a generalized sliding mode approach is developed that guarantees that the real-life system tracks, without any chatter and to within pre-specified error bounds, the control requirements that are imposed on the nominal system. Thus an explicit closed-form control for an uncertain, nonlinear, nonautonomous multi-body system that satisfies trajectory control requirements placed on the nominal system (to within pre-specified error bounds), is obtained. An example of a triple pendulum in which there are uncertainties both in the description of its physical parameters and in the description of the gravity field in which it moves is considered. The example demonstrates the simplicity and efficacy of the approach when there are uncertainties both in the description of a dynamical system and in the given forces to which it is subjected.

In this work the stability of TiN and TiC nanopowders in isopropyl alcohol as well as the fabrication of dense and well adhered thin coatings based on TiN and TiC by electrophoretic deposition (EPD) have been evaluated in terms of zeta potential and mass deposited when hydrazine is added. The surface of TiN and TiC nanoparticles has been modified to improve the dispersion in isopropyl alcohol adding a cationic polymer (polyethylenimine) as dispersant with two different molecular weights. The influence of acidic/basic character of the solvent also has been evaluated in order to reach the most efficient EPD process. It was found that the adsorption of polyethylenimine with higher molecular weight can preserve the homogeneity of TiC coatings. The surface of TiN nanoparticles can be tuned in order to achieve a similar polyethylenimine adsorption which also improves the deposition in basic media. [less ▲]

In last decades, farmland biodiversity came under large threat. To counteract farmland biodiversity loss and other environmental impacts of intensive agriculture, European farmers can apply Agri-environmental schemes. One of these is the creation of flower strips, a part of the cropping field where flowers are sown or naturally settled. Flower strips are known to increase biodiversity in the agricultural landscape, notably attracting specific insects groups, such as pollinators and natural enemies that can provide valuable pollination and biocontrol services to the crop. However, the plant species composition and management of the strips can have a large influence on the identity and amount of useful insects present in the strips, suggesting the need to develop tailored flower strips to maximize the services delivered. Functional diversity (FD) is sometimes proposed as a promising approach, focusing on plant functional traits rather than plant species itself. Yet, it is not certain that sowing a set of plant species results in the desired vegetation with the desired functional trait composition. Species from soil seed bank or dispersing from neighboring vegetation can settle in the strip, while sown species might not always be equally adapted to local conditions. To test this, we developed seed mixtures with four different levels of FD, based on flower traits, and sew them as flower strips in a conventional arable field. We monitored the vegetation to calculate the FD of the realized vegetation. While the absolute FD values of the realized vegetation were lower than the expected FD values, the realized vegetation showed the same FD gradient as expected from the sown mixtures, indicating that it is possible to manipulate FD in flower strips.

Insults, gossip, and slander are the origin of many conflicts during the Ancien Régime. They are used to hurt someone’s honour or reputation, which are essential values to keeping good relationships in society. People need to defend their honour when they are injured. They can seek reparations by taking legal action or opting for infrajudicial practices, such as contacting a notary. This possibility has attracted too little attention from historians whereas notarial records are a massive source of information related to conflicts affecting people's daily lives. Indeed, during the eighteenth century, inhabitants of Liège contacted a notary in order to find an agreement, clear their name of an insult, or to write their version of an aggression. [less ▲]

Reducing pesticide use is one the major issues of today’s agriculture. Among other possibilities, attracting and conserving pest natural enemies in agricultural landscapes by providing them habitats is promising. Wildflower strips (WFS) sown at field margins are one of these potential habitats. They are known to attract and conserve a large diversity of insects, as they provide them food resources such as pollen and nectar, as well as shelter and overwintering sites. However, the risk of attracting insect pests at field margins may represent an obstacle to their adoption by farmers. Conversely, it would be interesting if such WFS could play the role of pest trap crops. In an experimental field sown with WFS intercropped with oilseed rape (OSR) (Brassica napus L.), its coleopteran pests were trapped in both WFS and OSR using yellow pan traps between April and June 2014. More than 130 000 Meligethes spp., Ceutorhynchus spp. and Psylliodes chrysocephalla (L.) adults were trapped. Meligethes spp., Ceutorhynchus spp. were significantly more abundant in the OSR compared with WFS when adults emerged and populations reached their abundance peak. Before and between these periods, the few adults trapped were significantly more abundant in the WFS compared with the OSR. Concerning P. chrysocephala, too few individuals were caught for analysis. Results showed that OSR was more attractive than WFS when coleopteran pests were abundant. In this study, WFS sown for insect conservation may neither favour insect pest conservation at field margin, nor be considered as trap crops. [less ▲]

La question du traitement à réserver aux « erreurs » a donné lieu à des réponses très différentes au cours de l’histoire de la didactique des langues étrangères. Pour la méthode grammaire-traduction, les erreurs étaient des fautes qu’il fallait sanctionner (et donc exclure) pour qu’elles ne se produisent plus, tandis que l’approche structuro-behavioriste tentait de les prévenir à l’aide d’exercices qui devaient neutraliser les interférences de la langue-source vers la langue-cible. Aujourd’hui, l’erreur constitue une preuve que l’apprentissage est en progrès, puisque l’acquisition d’une langue suppose que l’apprenant élabore et vérifie des hypothèses sur son fonctionnement. C’est précisément au traitement des erreurs dans une approche communicative que nous avons choisi de nous intéresser ici. Nous nous proposons – en un premier stade – d’étudier les représentations d’enseignants de FLES et de leurs apprenants, interrogés sur leur conception et leur attitude concernant des erreurs commises ou rencontrées, et la/des norme(s) qui leur ser(ven)t de référence. À un second stade, nous verrons à quels niveaux se manifeste leur « conscience linguistique » en les exposant à une série d’énoncés considérés communément comme erronés, des « déviances-types », qu’ils devront repérer, identifier, évaluer. Par la même occasion, nous interrogerons la prégnance du clivage langue/communication chez nos témoins. [less ▲]

HD 93129A is a binary system including an O2 If+ and probably an O3.5 V-star orbiting at a distance of about 140 AU (55 mas given the distance of 2.5 kpc), which potentially makes the system the most massive one in the Galaxy, ahead of eta-Carina. Its non-thermal radio emission was proposed to be originated by the collision between the winds of both stars. HST/FGS data have been reanalyzed to derive an accurate absolute position of the stars to compare them with the radio emission. The analysis of ATCA radio observations along several years reveals a power-law spectrum with an increase on the radio flux density along time. We conducted an observation with the Australian Long Baseline Array (LBA) at 2.3 GHz in 2008 to resolve the radio source and its location within the stellar system. These radio data revealed a bow-shape extended emission located between both stars, as expected in a wind collision region. The observed structure allows us to roughly estimate the mass-loss rate ratio for the two stars in the system, concluding that it is about 0.7. The multiwavelength analysis points out that the detected radio emission is likely to be originated by one of the most massive collision wind binary in the Galaxy. [less ▲]

TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) is a 60-cm robotic telescope that has been installed in June 2010 at the ESO La Silla Observatory [1]. Operated from Liège (Belgium) it is devoted to the detection and characterisation of exoplanets and to the study of comets and other small bodies in the Solar System. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins filters. We describe here the hardware and the goals of the project. For relatively bright comets (V < 12) we measure several times a week the gaseous production rates (using a Haser model) and the spatial distribution of several species among which OH, NH, CN, C2 and C3 as well as ions like CO+. The dust production rates (Afrho) and color of the dust aredetermined through four dust continuum bands from the UV to the red (UC, BC, GC, RC filters). We will present the dust and gas production rates of the brightest comets observed in 2014: C/2012 K1 (PANSTARRS), C/2014 E2 (Jacques), C/2013 A1 (Siding Springs) and C/2013 V5 (Oukaimeden). Each of these comets have been observed at least once a week for several weeks to several months. Light curves with respect to the heliocentric distance will be presented and discussed.

C/2013 A1 (Siding Spring) is a long period comet discovered by Robert H McNaught at Siding Spring Observatory in Australia on January 3, 2013 at 7.2 au from the Sun. This comet will make a close encounter with Mars on October 19, 2014. At this occasion the comet will be extensively observed both from Earth and from several orbiters around Mars.On September 20, 2013 when the comet was around 5 au from the Sun, we started a monitoring with the TRAPPIST robotic telescope installed at La Silla observatory [1]. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins B, V, Rc, and Ic filters.We observed the comet continuously at least once a week from September 20, 2013 to April 6, 2014 with broad band filters. We then recovered the comet on May 20. At this time we could detect the gas and started the observations with narrow band filters until early November, covering the close approach to Mars and the perihelion passage.We present here our first results about comet Siding Springs. From the images in the broad band filters and in the dust continuum filters we derived A(θ)fρ values [3] and studied the evolution of the comet activity with the heliocentric distance from September 20, 2013 to early November 2014. We could also detect gas since May 20, 2014. We thus derived gas production rates using a Haser model [4]. We present the evolution of gas production rates and gas production rates ratios with the heliocentric distance.Finally, we discuss the dust and gas coma morphology. [less ▲]

Comet C/2012 S1 (ISON) was one of the Oort cloud comets and dynamically new. This comet was broken at its perihelion passage on UT 2013 November 28.1 (at Rh ~ 17 solar radius). We observed the comet C/2012 S1 (ISON) on UT 2013 November 15 with the High Dispersion Spectrograph (HDS) mounted on the Subaru Telescope atop Mauna Kea, Hawaii. Its heliocentric and geocentric distances were 0.601 and 0.898 AU, respectively. We selected the slit size of 0”.5 x 9”.0 on the sky to achieve the spectral resolution of R = 72,000 from 550 to 830 nm. The total exposure time of comet C/2012 S1 (ISON) was 1200 seconds. We detected many emission lines caused from radicals (e.g., CN, C2, NH2), ions (H2O+), atoms ([OI] and Na I) and also many unidentified lines in the spectra. We report the (1) the ortho-to-para abundance ratios (OPRs) of water and ammonia estimated from the high-dispersion spectra of H2O+ and NH2, (2) the green-to-red line ratio of forbidden oxygen emissions, (3) the isotopic ratios of C2 (the carbon isotopic ratio from Swan band) and CN (the carbon and nitrogen isotopic ratios from red band), (4) the sodium-to-continuum ratio of comet C/2012 S1 (ISON). </PRE></BODY></HTML> [less ▲]

The aim of this study was to evaluate the physico-chemical stability of Belgian Blue beef packaged under high-oxygen atmosphere as a function of a previous aging technique (wet-aging in vacuum conditions vs. carcass-aging). Two muscles (longissimus dorsi vs. rectus femoris) were studied. After a seven-day wet- or carcass-aging step, muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. Each 14 days, part of these samples was repackaged under modified atmosphere (70 % O2:30 % CO2), and stored during 7 days at +4 °C. The following parameters were evaluated: color, metmyoglobin %, metmyoglobin reducing activity, fat content, fatty acid profile, lipid oxidation, antioxidant enzyme activities and alpha-tocopherol content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage.

Introduction Cancer is a major health problem widespread in elderly, which is inscribed in ageism context1. Negative influence of the vision that older people possess on aging on mental and physical health2 is well established within “normal” aging. Consequently, we can ask ourselves what consequences age stigmas have in the realm of oncogeriatry. Moreover, cancerous patients face pathology-related stigmas because nowadays cancer still conveys a lot of negative representations. Method A group of 120 patients aged of 65 years old and more suffering from cancer (lung, breast or gynecological) will be followed during one year (0-3-6-12 months). Different instruments measuring quality of life, depression, symptoms, etc. are used as well as questions about their vision of aging and of cancer. Clinical parameters (weight, biologicals values, comorbidity…) are recorded too. Currently, we have 63 patients (31 breast cancer, 14 gynecological cancer and 18 lung cancer with distinction between smokers and non-smokers). Our analysis is only on the baseline at this moment, without any distinction between kinds of cancers. Results Double ANOVAs were used to analyze the data. A positive vision of aging is linked to a lower level of depression in comparison to a negative vision of aging (p = .04). Vision of pathology approach significance: less depression when vision is positive (p = .077). Concerning daily functioning (physical, emotional, social...), a positive vision of aging is related to a better functioning (p = .03) whereas vision of pathology has no effect. Eventually, a positive vision of aging and of cancer is related to a better quality of life (respectively p=.02, p=.002). Concerning clinical parameters, no results are observed. Conclusion These first results suggest that the vision patients have themselves of the age and of cancer is in relation with subjective mental and physical health. As we observe influence on vision of aging as well as pathology, we can talk about “double stigmatization”. Needless to say, more studies are needed to analyze the direction of these observation and longitudinal data analysis could bring some answers: is stigmatization provoke a less good mental and physical health or is it because I have health problem that I have a negative vision of aging and of my disease? 1.

Background: Population based studies have shown evident benefit in terms of mortality from screening for Abdominal Aortic Aneurysm (AAA) among men aged over 65. However, recent studies from USA, UK and Sweden suggest a decrease in the prevalence of AAA in the general population. Whether these findings are generalizable for the rest of Europe is unknown. Thus we decided to set up a screening program in order to detect AAA in Liege, Belgium. Material and Methods: During our ongoing study, over a first 3-month period, abdominal aortic ultrasound was performed on 541 participants, (198 women 343 men) to measure the maximal suprarenal and infrarenal aortic outer-outer diameter as well as the maximal diameter of the common iliac arteries. Moreover, we have measured arm and ankle blood pressure in each subject and the clinical characteristics of the patients, were collected. Results: The overall AAA prevalence was 4.62% (n = 25). In female participants aged ≥ 74 years the AAA prevalence amounted 1.01 %. While in male patients aged ≥ 65 years, it rose to 6.71%. Statistical analysis showed that male gender, aging, history of ischemic heart diseases, hyperlipidemia and varicose veins were significantly associated with AAA. Conclusion: Despite a reported declining prevalence of AAA in some recent population-based studies, we found that the prevalence of AAA in Liège population remains high in men aged 65 years or more. The prevalence of AAA seems to vary in different geographical regions. However, we need a larger sample to confirm our preliminary findings. [less ▲]

In this contribution, the formability of sheet metal cut edges is investigated using damage model.Classical forming limit diagrams are known not to apply properly to the cut edges. However, with mild steels the sheet edges usually behave better than the Forming Limit Diagram prédictions, so this phenomenon has not been given sufficient attention. In contrast, for Advanced High Strengh Steels the cut edges exhibit reduced formability as compared to the plain sheet;this effect is very sensitive to the quality of the cutting process. The current investigation is aimed to evaluate the ability of available damage models to predict this effect on sample applications. The Gurson-Tvergaard-Needleman model is used and the material parameters for a Dual Phase are considered [1]. The effect of the cutting process is described by means of initial fields of equivalent plastic strain and porosity. The geometrical distribution and typical values for these two initial fields are devised based on literature . Numerical simulations of flat notched tensile tests are used within the FE code Abaqus/Explicit to illustrate the impact of the initial fields on the moment and the location of the failure initiation. The influence of the mesh size in the cutting-affected area is also investigated. The hole expansion test and a flat bending test are further simulated to investigate the influence of the cut edge.

Purpose: Successful downstaging of hepatocellular carcinoma (HCC) into the Milan criteria (MC) remains a controversial indication for orthotopic liver transplantation (OLT). In Belgium, successful downstaging of HCC is an accepted non-standard- ized exception (NSE) for liver allocation. This NSE group rep- resents a unique cohort to analyse if OLT can be safely offered to patients with those extended allocation criteria. The aim of this study is to compare the overall and recurrence free survival after cadaveric OLT between patients with successful downstaging (MILDOWN) and patients always inside the MC (MILIN) from all Belgian transplant centres. Methods: We ret- rospectively analysed all patients listed for OLT with HCC and underlying cirrhosis between 12/2006 and 12/2011 from all Belgian liver transplant centres. Successful downstaging was defined as bringing a patient who was outside the MC into the MC after locoregional therapy (LRT). Results: Overall 381 patients were listed in Belgium during the study period. Of these, 320 received OLT. 248 were MILIN, 62 were MIL- DOWN and 10 were transplanted outside MC. Downstaging treatment included transarterial chemoembolization (TACE; n=26), radiofrequency (RF; n=9), transarterial radioembolisa- tion (TARE; n=4), resection (n=3), percutaneous ethanol injec- tion (n=2) and a combination of the above-mentioned therapies in 18 cases. In the MILIN group 67.3% received locoregional therapy before transplantation, with no significant differences in the distribution of treatment type compared to the MIL- DOWN group. At listing there were no significant differences between the MILIN and MILDOWN group for age, gender and underlying liver disease. Median time on waiting list between the two groups was similar (120 days vs. 115.5 days). Overall survival at 1 year was not significantly different between MILIN and MILDOWN (87.1% vs. 79%; p=0.120). 1.6% of patients were lost to follow-up in both groups. Although not significant, recurrence free survival at 1 year tended to be higher in the MILIN group than in the MILDOWN group (83.9% vs. 74.2%; p=0.073). Conclusion: In this large Belgian multicentre cohort, overall and recurrence free survival at 1 year are not signifi- cantly different between patients who have been downstaged successfully and patients who were always inside the Milan criteria. However, a longer follow up period will define, if the trend of lower survival in the successfully downstaged group becomes significant. Factors associated with HCC recurrence have to be identified.

Multi-Chromatic or spectral Analysis (MCA) of SAR images consists in splitting wide band SAR signals into sub-bands to generate several lower resolution images from a single acquisition. This splitting allows performing a spectral analysis of observed scatterers. Spectral coherence is derived by computing the coherence between sub-images issued from a single SAR acquisition. It was shown that in the presence of a random distribution of surface scatterers, spectral coherence is proportional to sub-band intersection of sub-images. This model is fully verified when observing spectral coherence on open seas areas. If the scatterers distribution departs from this distribution, like for manmade structures, spectral coherence may be preserved to a certain degree. We investigated the spectral coherence to perform vessel detection on a sea background by using spotlight images acquired on the Venice Lagoon. Sea background tends to lead to very low spectral coherence while this latter is preserved on the targeted vessels, even for very small ones. A first analysis shows that all vessels observable in intensity images are easily detected in the spectral coherence images which can be used as a complementary information channel to constrain vessel detection.

INTRODUCTION. Renal dysfunction often occurred after liver transplantation. OBJECTIVES. The aim of the study was to determine its incidence and its risk factors in a clinical series at the University Hospital of Liege, Belgium. METHODS. Orthotopic liver transplantations performed from January 2006 until Sep- tember 2012 were retrospectively reviewed (n = 187). Patients, with no renal replacement therapy (RRT) before transplantation were classified in four groups according to their highest creatinine plasma level during the first postoperative week. First group had a cre- atinine level below 12 mg/l, the second group between 12 and 20 mg/l, the third group between 20 and 35 mg/l, and the fourth above 35 mg/l. In addition, patients who needed RRT during the first week after transplantation were also classified in the fourth group. Preoperative and perioperative parameters were tested as risk factors: age, sex, body mass index (BMI), length of hospital preoperative stay, prior bacterial infection within one month, preoperative ascites, preoperative treatment with ß-blocker, converting enzyme inhibitor, or non steroidal antiinflammatory drugs, preoperative creatinine and bilirubine level, postop- erative lactate level, need for postoperative vasopressive drugs, surgical revision, mechanical ventilation for more than 24 h, postoperative peaks in bilirubine and transam- inase levels, postoperative hemoglobin level, amount of perioperative blood transfusions, type of immunosuppression. Univariate and multivariate analysis were performed using logistic ordinal regression method. RESULTS. There were 78 patients in group 1 (41.7 %), 46 in group 2 (24.6 %), 38 in group 3 (20.3 %) and 25 in group 4 (13.4 %). Eighteen patients required RRT: 13 (7 %) during the first week after transplantation (group 4), the 5 others after the first week after transplan- tation (2 in group 1 and 2, and 1 in group 3). There were 7 (3.7 %) early deaths within 28 days after transplantation. Using univariate analysis, the severity of renal dysfunction was correlated with presence of ascites and prior bacterial infection, preoperative bilirubin and creatinine level, need for surgical revision, use of vasopressor, postoperative mechanical ventilation, postoperative bilirubine, transaminase, and hemoglobin levels. The need for transfusion of each type of products also affected renal dysfunction. The ordinal logistic analysis pointed out the BMI (OR = 1.1, p = 0.004), preoperative creatinine level (OR = 11.1, p \ 0.0001), use of vasopressor (OR = 3.31, p = 0.0002), maximal postop- erative bilirubine level (OR = 1.44, p = 0.044) and minimal postoperative hemoglobin level (OR 0.059 p = 0.0005). CONCLUSIONS. More than half of liver transplanted patients experienced some degree of early renal dysfunction after transplantation. Risk factors are preoperative renal dysfunction, and mainly perioperative circulatory instability requiring the use of vasopressor and post- operative anemia. [less ▲]

Precision livestock farming is emerging in the wake of the technological developments in remote sensing and motion monitoring. Tools are developed to allow accurate real time monitoring of the individual cattle behaviour in a quest to improve the management of pastures. Studies have shown the relevancy of accelerometers in the analysis of behaviour using dedicated devices. Accelerometers are located either close to the mouth or jaw of the animal or on its forehead or neck. Records are usually performed at low frequency (<1Hz) and most studies classify behaviours using neuronal networks or multivariate statistical approaches, with little consideration to the animals’ actual movements. Inertial measurement units (IMU) in consumer mobile devices are specifically developed to record accurately user movements. Besides 3D-accelerometer, they can include 3-D rotational speed sensors, 3-D magnetometers and GPS. Optimised power consumption offers significant autonomy. Data directly acquired from the sensors and IMU signals from build-in proprietary algorithms can be recovered using user-friendly low-cost applications. Moreover, mobile devices can store or communicate information by wireless in real time at high frequency. As movements of cattle are in the same range as humans, this study investigates the relevancy of mobile devices IMU signals to discriminate main behaviours of cattle on pasture. [less ▲]

Medications often partially alleviate the symptoms of RLS patients, emphasizing the need for finding alternative treatments. Recent studies reported an efficacy of bright light therapy (BLT) in Parkinson disease. RLS pathogenesis involves the dopaminergic system and light has been shown to influence the dopaminergic tone. Therefore, the objective of our study was to determine the therapeutic value of three weeks of BLT on RLS symptoms severity, sleep quality, daytime somnolence, circadian rhythms and mood. [less ▲]

True hermaphroditism in horses, is a complex and poorly under- stood disorder of sexual development characterized by the presence of both male and female gonads as separate organs or in a combined structure called ovotestis. A 3-year-old Spanish nullipa- rous mare with a history of stallion behaviour and an abnormal reproductive exam was presented at the Equine Clinic of the University of Li ege. Externally, a small vulva with an enlarged clitoris was observed. Transrectal ultrasonography showed a thin (<1 cm) uterus, leading to a small heterogeneous structure in the normal place of the left ovary. No structure could be identified in the presumed location of the right ovary. Speculum exam was compatible with a vaginal agenesis, as the cervix opened craniad the urethral meatus. Oestradiol, progesterone and testosterone concen- trations were compatible with a stallion’s endocrinology. Gonads were laparoscopically found in the usual location of the ovaries in both flanks and excised. Histopathology of both gonads showed atrophic testicular tissue with hyperplastic Leydig cells. The left gonad also contained ovarian tissue with some scarce primordial follicles. Clitoral enlargement is the first symptom most commonly identified in animals with true hermaphroditism and can be explained by the production of testosterone by the gonads, however, the aetiology of the vaginal agenesis is unknown. True hermaph- roditism in horses is generally related to 64XX syndrome with or without SRY gene translocation (impending karyotyping analysis). After 5 days the mare was discharged from the clinic, and in absence of testosterone the stallion behaviour disappeared in a couple of months. [less ▲]

INTRODUCTION. Depression is a common psychopathology characterized by a decrease of the level of behavioural activation (BA) that is the level of engagement in activities. The relationship between depression and BA is well-established in the scientific literature. According to theoretical models of depression, psychopathology is also characterized by biases in five sets of psychological processes (PP): self-image (e.g. self-esteem), negative repetitive thoughts (e.g. ruminative thoughts), experiential avoidance (e.g. mindfulness), environmental satisfaction (e.g. environmental reward observation) and emotional regulation (e.g. distress tolerance). Therefore, the present study aims to identify PP mediating the relationship between depression and the level of BA. In order to reach this objective, a conceptual model is tested. METHOD. 361 adults (x ̅ age=36, σ=15), from clinical and non-clinical settings, fulfilled a series of questionnaires assessing several variables: sociodemographic data, depression, anxiety, level of BA and the above-cited five sets of PP. Covariance structure analysis will be conducted in order to test the conceptual model mentioned above. RESULTS. Some preliminary results are presented. As expected, a negative significant correlation between depression and BA (r=-.66, p<.01) have been highlighted. Negative significant correlation appeared between BA and the measured PP: self-esteem (r=-.27, p<.01), ruminative thinking (r=-.53, p<.01), environmental reward observation (=-.13, p<.05). Positive significant correlations appeared between BA and mindfulness (r=.49, p<.01) and distress tolerance (r=.26, p<.01). DISCUSSION. The preliminary results are in line with our hypotheses. Indeed, the level of BA is negatively linked to PP usually biased in depression such as self-esteem. The mediating role of these PP between depression and the level of BA will be discussed. [less ▲]

Investigations on steel thixoforming started in the early 90’s and many developments were carried out, mainly driven by the industrialization of the process. After a series of basic investigations on adapted steels and materials as well as near-net shaping investigations, the issue of mass production raised and thus induced some other challenges mainly on die life and process automation and cycling. High working temperatures and components complexity were then the main locks to mass productions. In most of reported literature, none of the involved research group reached or real production and industrialization criteria. The euro group holds most of these research investigations [1]. We have reported many of these results in previous communications and this paper presents a continuity of what have already been presented. Some advanced tooling materials and solutions are presented and applied to a real complex industrial component. © (2015) Trans Tech Publications, Switzerland. [less ▲]

Genetic selection programs aiming to mitigate methane (CH4) emissions require the estimation of genetic correlations with other production and economical traits and predicted selection response. CH4 intensity was predicted from Mid-infrared spectra of milk samples from Holstein cows. Genetic correlations between CH4 intensity and milk yield (MY) was -0.68, fat yield (FY) -0.13, protein yield (PY) -0.47, somatic cell score (SCS) 0.07, longevity 0.05, fertility 0.31, body condition score (BCS) 0.17. Adding 25% relative weight on CH4 intensity to the current Walloon selection index, the response to selection would reduce CH4 intensity by 24%, increase MY by 30%, FY by 17%, PY by 29%, SCS by -14%, longevity by 24% but also reduce fertility by 11% and BCS by 13%. In conclusion, environmental traits can be added without jeopardizing production traits, but energy balance related traits have to be protected. [less ▲]

We present the first observations obtained with the L'-band AGPM vortex coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase Mask) is a vector vortex coronagraph made from diamond subwavelength gratings. It is designed to improve the sensitivity and dynamic range of high-resolution imaging at very small inner working angles, down to 0.09 arcseconds in the case of LBTI/LMIRCam in the L' band. During the first hours on sky, we observed the young A5V star HR8799 with the goal to demonstrate the AGPM performance and assess its relevance for the ongoing LBTI planet survey (LEECH). Preliminary analyses of the data reveal the four known planets clearly at high SNR and provide unprecedented sensitivity limits in the inner planetary system (down to the diffraction limit of 0.09 arcseconds). © 2014 SPIE.

Introduction: The equine suspensory ligament (SL) injuries are an important cause of lameness in horses. Quantification of the relative abundance of the constitutive collagen types is essential to investigate the differences between normal and injured tissues. The aim of this original study was to precisely determine the different collagen ratios both in injured and normal SL. This approach is a rational step towards understanding the intimate mechanisms of SL repair and regeneration at the molecular and histological levels. Methods: Five Warmblood horses with visible signs of injury in only one forelimb SL were selected. Specimens were obtained from the central core of lesions in damaged SLs and from the corresponding regions in other healthy SLs. Collagen types I, III and V were purified by differential salt precipitation after collagen extraction with acetic acid containing pepsin and they were examined by transmission electron microscopy. The bands corresponding to types I, III, and V collagen were assessed by densitometry after SDS-PAGE. SAS software (SAS Institute 2001) was used for all statistical analyses. Results: Based on ultrastructural observations, purified fibers of types I, III, and V collagens have been identified. The relative proportions of type III and type V collagen were significantly higher in the specimens‎ from damaged tissue compared with specimens from normal tissue (P < 0.001). These changes were concomitant with significant decrease in type I collagen in the injured tissue (P < 0.001). Conclusions: Our study showed that after SL injury, the relative abundance of the different collagen types is modified. These changes are the molecular hallmark of a decrease in tissue quality and mechanical properties of the ligament. It lays down the bases of subsequent researches on the tissue regeneration that may lead to the development of new treatment strategies for damaged tissues, particularly in the equine SL injuries.

In market economies, homeownership is associated with positive ex- ternalities. Increasing the levels of homeownership has been an objective of governments for the last decades. The analysis of the determinants of tenure sta- tus provides information to this end. This paper proposes an econometric analysis of housing tenure in Belgium. We review the main variables that have been considered in the literature as influencing housing tenure, after what we estimate a logit model. We observe a strong influence of income and age on the probability of homeownership. Couple relationship and the presence of dependent children have a positive influence, but this influence is less significant. Urban location is associated with lower probability of homeownership, compared with other areas. Our observations follow the trends described for other countries in the literature. [less ▲]

Solar Orbiter EUI instrument was submitted to a high solar flux to correlate the thermal model of the instrument. EUI, the Extreme Ultraviolet Imager, is developed by a European consortium led by the Centre Spatial de Liège for the Solar Orbiter ESA M-class mission. The solar flux that it shall have to withstand will be as high as 13 solar constants when the spacecraft reaches its 0.28AU perihelion. It is essential to verify the thermal design of the instrument, especially the heat evacuation property and to assess the thermo-mechanical behavior of the instrument when submitted to high thermal load. Therefore, a thermal balance test under 13 solar constants was performed on the first model of EUI, the Structural and Thermal Model. The optical analyses and experiments performed to characterize accurately the thermal and divergence parameters of the flux are presented; the set-up of the test, and the correlation with the thermal model performed to deduce the unknown thermal parameters of the instrument and assess its temperature profile under real flight conditions are also presented.

This paper presents predictions of space radiation parameters for four space instruments performed by the Centre Spatial de Liège (ULg – Belgium); EUI, the Extreme Ultra-violet Instrument, on-board the Solar Orbiter platform; ESIO, Extreme-UV solar Imager for Operations, and JUDE, the Jupiter system Ultraviolet Dynamics Experiment, which was proposed for the JUICE platform. For Solar Orbiter platform, the radiation environment is defined by ESA environmental specification and the determination of the parameters is done through ray-trace analyses inside the EUI instrument. For ESIO instrument, the radiation environment of the geostationary orbit is defined through simulations of the trapped particles flux, the energetic solar protons flux and the galactic cosmic rays flux, taking the ECSS standard for space environment as a guideline. Then ray-trace analyses inside the instrument are performed to predict the particles fluxes at the level of the most radiation-sensitive elements of the instrument. For JUICE, the spacecraft trajectory is built from ephemeris files provided by ESA and the radiation environment is modeled through simulations by JOSE (Jovian Specification Environment model) then ray-trace analyses inside the instrument are performed to predict the particles fluxes at the level of the most radiation-sensitive elements of the instrument.
