description: Compared to technical infrastructure, nature-based solutions (NBS) strive to work with nature and to move beyond business-as-usual practices. Despite decades of research from various academia fields and a commencing mainstreaming of the term, a lack of cohesiveness and pertinent methods regarding the subject matter hinders further implementation. Using a functional landscape approach, this paper aims to identify the spatial extent of existing and potential NBS locations and applies it across a case study in Germany. Inspired by hydrological models, which work with delineated hydrological response units, this research instead defines hydromorphological landscape units (HLU) based on biophysical spatial criteria to identify the potential areas that could function as NBS. This approach was tested for floodplain-based NBS. The identified HLU were then compared with historical floodplain and land-use data to differentiate between active or potential NBS. The spatial delineation identified 3.6 million hectares of already active floodplains areas, for which we recommend continued or modified protection measures, and 0.4 million ha where the hydromorphological conditions are apt to support floodplains, yet are cut-off from the flooding regime and require rehabilitation measures. The identification of NBS through explicitly defined HLU serves as a spatial approach to support NBS implementation. Taken together, our research can provide an essential contribution to systemize the emerging scholarship on NBS in river landscapes and to help in selecting and planning appropriate NBS in practice.

description: We study a generalization of a Pais-Uhlenbeck oscillator for fermionic variables. Next, we consider an ensemble of these oscillators and we identify a particular case of the Myers-Pospelov model which is relevant for effective theories of quantum gravity. Finally, by taking the advantage of this connection, we analyze, for this model, the unitarity at one loop order in the low energy regime where no ghost states can be created on-shell. This energy regime is the relevant one when we consider the Myers-Pospelov model as a true effective theory coming from new space-time structure.

description: 23Na NMR studies of the Na-K eutectic alloy embedded into porous glass with 7 nm pores showed that melting of Na2K confined nanoparticles is a continuous process with smooth changes in the Knight shift of a narrow resonance line and nuclear spin relaxation between those in the crystalline and liquid states. The intermediate state which occurs upon melting is stable and more favorable than the liquid state. The inverse freezing transformation can be sharp as at a first order transition or continuous depending on the initial temperature of cooling. The results suggest revision of theoretical predictions for the melting and freezing transitions in confined geometry.

description: Changes of surface gravity on Earth are of great interest in geodesy, earth sciences and natural resource exploration. They are indicative of Earth system's mass redistributions and vertical surface motion, and are usually measured with falling corner-cube- and superconducting gravimeters (FCCG and SCG). Here we report on absolute gravity measurements with a mobile quantum gravimeter based on atom interferometry. The measurements were conducted in Germany and Sweden over periods of several days with simultaneous SCG and FCCG comparisons. They show the best-reported performance of mobile atomic gravimeters to date with an accuracy of 39nm/s2, long-term stability of 0.5nm/s2 and short-term noise of 96nm/s2/√Hz. These measurements highlight the unique properties of atomic sensors. The achieved level of performance in a transportable instrument enables new applications in geodesy and related fields, such as continuous absolute gravity monitoring with a single instrument under rough environmental conditions.

description: Objectif. Une enquête a été proposée à 9 établissements d’Ille-et-Vilaine ayant une activité de soins de suite et réadaptation ou de gériatrie, notamment afin d’identifier les freins à l’utilisation des produits hydro-alcooliques (PHA) des professionnels. Méthode. Un questionnaire comportant 24 propositions de freins a été transmis ; les professionnels pouvaient cocher la ou les propositions correspondant à leurs opinions. Résultats. Huit des 9 établissements ont participé à cette enquête. 470 questionnaires ont été recueillis, représentant 1 293 freins à l’utilisation des PHA. Les 4 freins les plus fréquemment retrouvés étaient : le PHA est irritant, desséchant (49 % des professionnels) ; je préfère me laver les mains (38 %) ; j’oublie de montrer au patient comment utiliser le PHA (35 %) ; le PHA est possiblement toxique pour ma santé (31 %). Sur l’ensemble des réponses, 9 % des salariés déclaraient n’avoir aucun frein à l’utilisation des PHA et le nombre moyen de freins par salarié était de 2,75. Ce nombre moyen variait cependant beaucoup suivant les établissements ainsi que le pourcentage de salariés n’ayant aucun frein, ce qui montre que la perception des PHA est aussi liée aux représentations individuelles et socioculturelles des salariés. Conclusion. Développer l’utilisation d’outils pédagogiques permettant de travailler sur les représentations, les comportements, la perception de l’hygiène des mains au cours des formations futures, devrait permettre d’améliorer l’hygiène des mains par friction au quotidien.

title: Sécurité et maîtrise du budget des dispositifs de prélèvement sanguin : une approche en coût complet

description: L’objectif était de déployer, au sein de notre établissement, des unités de prélèvement plus sécurisées pour réduire les accidents d’exposition au sang (AES) liés aux prélèvements sanguins, tout en optimisant le budget attribué aux dispositifs médicaux utilisés pour ceux-ci. L’analyse de ce budget, de 2003 à 2012, a montré une augmentation croissante du coût moyen de ce type de prélèvements, principalement liée à l’accroissement de l’utilisation des unités à ailettes pour ceux-ci. Dans les situations où cette utilisation était injustifiée, pour la stopper tout en maintenant la sécurité des prélèvements sanguins concernés, nous avons déployé des aiguilles droites avec visualisation du reflux veineux moins coûteuses que ces unités à ailettes. Dans les situations où l’utilisation de ces dernières était justifiée, nous avons pu les remplacer par leur modèle dernière génération, afin de mieux sécuriser nos prélèvements les plus à risque d’AES. Grâce à une approche en coût complet, nous avons donc introduit un matériel plus adapté à chaque situation de prélèvement sanguin. Enfin nous avons accompagné la mise en place de ces deux dispositifs médicaux d’une campagne de formation puis d’une évaluation des pratiques professionnelles. Entre 2013 et 2016 les pratiques de soins ont ainsi évolué positivement, la consommation des unités à ailettes ayant été réduite. Cette mise en place a été faite à budget constant, la baisse de la consommation des unités à ailettes ayant financé le surcoût lié à l’investissement dans leur modèle dernière génération.

description: We explore the consequences of heavy flavour, heavy quark spin and heavy antiquark-diquark symmetries for hadronic molecules within an effective field theory framework.. Owing to heavy antiquark-diquark symmetry, the doubly heavy baryons have approximately the same light-quark structure as the heavy antimesons. As a consequence, the existence of a heavy meson-antimeson molecule implies the possibility of a partner composed of a heavy meson and a doubly-heavy baryon. In this regard, the D\bar D* molecular nature of the X(3872) will hint at the existence of several baryonic partners with isospin I=0 and J^P = 5/2^- or 3/2^-. Moreover, if the Zb(10650) turns out to be a B*\bar B* bound state, we can be confident of the existence of \Xibb* \bar B* hadronic molecules with quantum numbers I(J^P) = 1(1/2^-) and I(J^P) = 1(3/2^-). These states are of special interest since they can be considered to be triply-heavy pentaquarks.

description: Boehmite nanoparticles show great potential in improving mechanical properties of fiber reinforced polymers. In order to predict the properties of nanocomposites, knowledge about the material parameters of the constituent phases, including the boehmite particles, is crucial. In this study, the mechanical behavior of boehmite is investigated using Atomic Force Microscopy (AFM) experiments and Molecular Dynamic Finite Element Method (MDFEM) simulations. Young's modulus of the perfect crystalline boehmite nanoparticles is derived from numerical AFM simulations. Results of AFM experiments on boehmite nanoparticles deviate significantly. Possible causes are identified by experiments on complementary types of boehmite, that is, geological and hydrothermally synthesized samples, and further simulations of imperfect crystals and combined boehmite/epoxymodels. Under certain circumstances, the mechanical behavior of boehmite was found to be dominated by inelastic effects that are discussed in detail in the present work. The studies are substantiated with accompanying X-ray diffraction and Raman experiments.

description: Results of a series of molecular dynamics simulations of cubic siliceous zeolites suggest that pressure-induced softening -- the phenomenon in which a material becomes progressively more compressible under pressure -- is likely to be a common feature of framework materials that show negative thermal expansion. The correlation between the negative thermal expansion and the pressure-induced softening is investigated on the basis of thermodynamics.
Cellular polarization: interaction between extrinsic bounded noises and wave-pinning mechanism

description: Cued and un-cued cell polarization is a fundamental mechanism in cell biology. As an alternative to the classical Turing bifurcation, it has been proposed that the cell polarity might onset by means of the well-known phenomenon of wave-pinning (Gamba et al, PNAS, 2005). A particularly simple and elegant model of wave-pinning has been proposed by Edelstein-Keshet and coworkers (Biop. J., 2008). However, biomolecular networks do communicate with other networks as well as with the external world. As such, their dynamics has to be considered as perturbed by extrinsic noises. These noises may have both a spatial and a temporal correlation, but any case they must be bounded to preserve the biological meaningfulness of the perturbed parameters. Here we numerically show that the inclusion of external spatio-temporal bounded perturbations may sometime destroy the polarized state. The polarization loss depends on both the extent of temporal and spatial correlations, and on the kind of adopted noise. Namely, independently of the specific model of noise, an increase of the spatial correlation induces an increase of the probability of polarization. However, if the noise is spatially homogeneous then the polarization is lost in the majority of cases. On the contrary, an increase of the temporal autocorrelation of the noise induces an effect that depends on the noise model.

description: Bridges are vulnerable to the fatigue damage accumulation caused by traffic loading over the service period. A continuous growth in both the vehicle weight and the traffic volume may cause a safety hazard to existing bridges. This study presented a computational framework for probabilistic modeling of the fatigue damage accumulation of short to medium span bridges under actual traffic loading. Stochastic truck-load models were simulated based on site-specific weigh-in-motion measurements. A response surface method was utilized to substitute the time-consuming finite element model for an efficient computation. A case study of a simply supported bridge demonstrated the effectiveness of the computational framework. Numerical results show that the simulated fatigue stress spectrum captures the probability density functions of the heavy traffic loading. The equivalent fatigue stress range increases mostly linearly in the good road roughness condition with the growth of the gross vehicle weight. The vehicle type and the road roughness condition affect the stress range. The influence of the driving speed on the equivalent stress range is non-monotonic. The bridge fatigue reliability has a considerable increase even under a relatively high overload limit. It is anticipated that the proposed computational framework can be applied for more types of bridges.

description: Citizen science is becoming increasingly popular as a format in environmental and sustainability education. Citizen science not only allows researchers to gather large amounts of biodiversity-related data, it also has the potential to engage the public in biodiversity research. Numerous citizen science projects have emerged that assume that participation in the project affects participants' knowledge, attitudes, and behavior. We investigated what evidence really exists about the outcomes of biodiversity citizen science projects on the side of the individual participants. For this purpose, we conducted a systematic review of peer-reviewed research articles published up to and including 2017. We found evidence for various individual participant outcomes. The outcome reported most often was a gain in knowledge. Other outcomes, found in several articles, referred to changes in behavior or attitudes. Outcomes reported less often were new skills, increased self-efficacy and interest, and a variety of other personal outcomes. We discuss the research design and methods used in the reviewed studies und formulate specific recommendations for future research. We conclude that citizen science is a promising option for environmental and sustainability education focusing on biodiversity. Partnerships between natural and social scientists in the design and evaluation of projects would allow future biodiversity citizen science projects to utilize their full educational potential.

description: Recent studies of dynamic self-assembly in ferromagnetic colloids suspended in liquid-air or liquid-liquid interfaces revealed a rich variety of dynamic structures ranging from linear snakes to axisymmetric asters, which exhibit novel morphology of the magnetic ordering accompanied by large-scale hydrodynamic flows. Based on controlled experiments and first principle theory, we argue that the transition from snakes to asters is governed by the viscosity of the suspending liquid where less viscous liquids favor snakes and more viscous, asters. By obtaining analytic solutions of the time-averaged Navier-Stokes equations, we gain insights into the role of mean hydrodynamic flows and an overall balance of forces governing the self-assembly. Our results illustrate that the viscosity can be used to control the outcome of the dynamic self-assembly in magnetic colloidal suspensions.

description: Citrus variegated chlorosis (CVC) is one of the most important diseases for Brazilian citriculture. It is caused by Xylella fastidiosa subsp. pauca, a xylem limited, cycadelid and budwood transmitted bacterium. In Bahia, the second most important citrus region in Brazil, CVC has been present since 1997. Our objectives were to characterize the regional spatial pattern of CVC and to establish a relationship between epidemiological variables and horticultural practices, as well as to evaluate whether control measures used so far have been effective and, based on that, to conceive suitable control measures. A series of surveys were performed in two regions of Bahia State (Recôncavo Baiano and Litoral Norte), along with a survey of horticultural and control practices associated with sampled groves. CVC was restricted to Litoral Norte region, especially to three municipalities along the border between Bahia and Sergipe States. The mean CVC incidence in these municipalities followed a gradient, higher in the countryside and decreasing along the coast. Presence and dissemination of CVC was related to poor nursery practices, a massive use of a susceptible orange variety, and an extreme concentration of orange groves in high incidence municipalities, as well as to the absence of specific CVC control. Considering that CVC was not found in Recôncavo Baiano, this region could be considered a "CVC free zone" by the local government. Copyright by the Brazilian Phytopathological Society.

description: A standard model for eruptive flares aims at describing observational 3D features of the reconnecting coronal magnetic field. Extensions to the 2D model require the physical understanding of 3D reconnection processes at the origin of the magnetic configuration evolution. However, the properties of 3D reconnection without null point and separatrices still need to be analyzed. We focus on magnetic reconnection associated with the growth and evolution of a flux rope and associated flare loops during an eruptive flare. We aim at understanding the intrinsic characteristics of 3D reconnection in the presence of quasi-separatrix layers (QSLs), how QSL properties are related to the slip-running reconnection mode in general, and how this applies to eruptive flares in particular. We studied the slip-running reconnection of field lines in a magnetohydrodynamic simulation of an eruptive flare associated with a torus-unstable flux rope. Field lines associated with the flux rope and the flare loops undergo a continuous series of magnetic reconnection, which results in their super-Alfvenic slipping motion. The time profile of their slippage speed and the space distribution of the mapping norm are shown to be strongly correlated. We find that the motion speed is proportional to the mapping norm. Moreover, this slip-running motion becomes faster as the flux rope expands, since the 3D current layer evolves toward a current sheet, and QSLs to separatrices. The present analysis extends our understanding of the 3D slip-running reconnection regime. We identified a controlling parameter of the apparent velocity of field lines while they slip-reconnect, enabling the interpretation of the evolution of post flare loops. This work completes the standard model for flares and eruptions by giving its 3D properties.

description: (Abridged) Far-infrared Herschel-PACS spectra of 18 low-mass protostars of various luminosities and evolutionary stages are studied. We quantify their far-infrared line emission and the contribution of different atomic and molecular species to the gas cooling budget during protostellar evolution. We also determine the spatial extent of the emission and investigate the underlying excitation conditions. Most of the protostars in our sample show strong atomic and molecular far-infrared emission. Water is detected in 17 objects, including 5 Class I sources. The high-excitation H2O line at 63.3 micron is detected in 7 sources. CO transitions from J=14-13 up to 49-48 are found and show two distinct temperature components on Boltzmann diagrams with rotational temperatures of ~350 K and ~700 K. H2O has typical excitation temperatures of ~150 K. Emission from both Class 0 and I sources is usually spatially extended along the outflow direction but with a pattern depending on the species and the transition. The H2O line fluxes correlate strongly with those of the high-J CO lines, as well as with the bolometric luminosity and envelope mass. They correlate less strongly with OH and not with [OI] fluxes. The PACS data probe at least two physical components. The H2O and CO emission likely arises in non-dissociative (irradiated) shocks along the outflow walls with a range of pre-shock densities. Some OH is also associated with this component, likely resulting from H2O photodissociation. UV-heated gas contributes only a minor fraction to the CO emission observed by PACS, based on the strong correlation between the shock-dominated CO 24-23 line and the CO 14-13 line. [OI] and some of the OH emission probe dissociative shocks in the inner envelope. The total far-infrared cooling is dominated by H2O and CO, with [OI] increasing for Class I sources.

description: When parameters are varied periodically, charge can be pumped through a mesoscopic conductor without applied bias. Here, we consider the inverse effect in which a transport current drives a periodic variation of an adiabatic degree of freedom. This provides a general operating principle for adiabatic quantum motors, for which we develop a comprehensive theory. We relate the work performed per cycle on the motor degree of freedom to characteristics of the underlying quantum pump and discuss the motor's efficiency. Quantum motors based on chaotic quantum dots operate solely due to quantum interference, motors based on Thouless pumps have ideal efficiency.

Traditionally, computer models are calibrated using deterministic procedures. However, different analysts produce different models based on different modelling approximations and assumptions. In addition, identically constructed structures and systems show different characteristic between each other. Hence, model updating needs to take account modelling and test-data variability. Stochastic model updating techniques such as sensitivity approach and Bayesian updating are now recognised as powerful approaches able to deal with unavoidable uncertainty and variability. This paper presents a high fidelity surrogate model that allows to significantly reduce the computational costs associated with the Bayesian model updating technique. A set of Artificial Neural Networks are proposed to replace multi non-linear input-output relationships of finite element (FE) models. An application for updating the model parameters of the FE model of the DRL-AIRMOD structure is presented. © 2017 The Authors. Published by Elsevier Ltd.

description: Transition metal oxide hetero-structure has great potential for multifunctional devices. However, the degraded physical properties at interface, known as dead-layer behavior, present a main obstacle for device applications. Here we present the systematic study of the dead-layer behavior in La0.67Sr0.33MnO3 thin film grown on SrTiO3 substrate with ozone assisted molecular beam epitaxy. We found that the evolution of electric and magnetic properties as a function of thickness shows a remarkable resemblance to the phase diagram as a function of doping for bulk materials, providing compelling evidences of the hole depletion in near interface layers that causes dead-layer. Detailed electronic and surface structure studies indicate that the hole depletion is due to the intrinsic oxygen vacancy formation. Furthermore, we show that oxygen vacancies are partly caused by interfacial electric dipolar field, and thus by doping-engineering at the single-atomic-layer level, we demonstrate the dead-layer reduction in films with higher interfacial hole concentration.

description: Objectifs. Décrire l’évolution du nombre de cas de grippe nosocomiale en gériatrie au CHU de Saint-Étienne entre 2012 et 2016 et la mettre en parallèle avec les mesures de contrôle mises en œuvre. Matériels et méthodes. Depuis 2012, un programme multifacette de gestion des épidémies de grippe a été mis en œuvre au sein de cet établissement. Il inclut, en complément des mesures classiques de prise en charge des patients grippés, la systématisation du port de masque par les personnels de santé et les visiteurs pendant la période épidémique, des campagnes de sensibilisation aux mesures barrières, à la vaccination, et la mise à disposition de vaccins antigrippaux dans les services. Un fichier informatique des diagnostics de grippe est envoyé quotidiennement par les virologues à l’unité de gestion du risque infectieux. Le caractère nosocomial ou communautaire est établi par l’équipe opérationnelle d’hygiène en lien avec les services cliniques. Il est vérifié que les patients sont bien placés en précautions complémentaires gouttelettes ou air selon le type de soin réalisé. Les données sont colligées dans un fichier Excel®. Résultats. Au sein du secteur gériatrique, 35 cas de grippe nosocomiale ont été recensés en 2012 (9 en court et moyen séjours et 26 en long séjour), 7 cas en 2013, 11 cas en 2014, 11 cas en 2015 et 3 cas en 2016, tous en court et moyen séjours. Une baisse du nombre de cas de grippe nosocomiale a été observée au fil des 5 ans en gériatrie (p < 0,001 par un test du χ2 de tendance) ; elle a été surtout patente en long séjour à la fin de la première année. Conclusion. La stratégie multifacette qui a été déployée a permis de mobiliser les différents intervenants autour d’une meilleure gestion de la grippe en gériatrie. Elle a certainement participé à la réduction des cas de grippe nosocomiale en long séjour.

description: Deformation monitoring of structures is a common application and one of the major tasks of engineering surveying. Terrestrial laser scanning (TLS) has become a popular method for detecting deformations due to high precision and spatial resolution in capturing a number of three-dimensional point clouds. Surface-based methodology plays a prominent role in rigorous deformation analysis. Consequently, it is of great importance to select an appropriate regression model that reflects the geometrical features of each state or epoch. This paper aims at providing the practitioner some guidance in this regard. Different from standard model selection procedures for surface models based on information criteria, we adopted the hypothesis tests from D.R. Cox and Q.H. Vuong to discriminate statistically between parametric models. The methodology was instantiated in two numerical examples by discriminating between widely used polynomial and B-spline surfaces as models of given TLS point clouds. According to the test decisions, the B-spline surface model showed a slight advantage when both surface types had few parameters in the first example, while it performed significantly better for larger numbers of parameters. Within B-spline surface models, the optimal one for the specific segment was fixed by Vuong's test whose result was quite consistent with the judgment of widely used Bayesian information criterion. The numerical instabilities of B-spline models due to data gap were clearly reflected by the model selection tests, which rejected inadequate B-spline models in another numerical example. © 2018 by the authors.

description: The increasing size and availability of web data make data quality a core challenge in many applications. Principles of data quality are recognized as essential to ensure that data fit for their intended use in operations, decision-making, and planning. However, with the rise of the Semantic Web, new data quality issues appear and require deeper consideration. In this paper, we propose to extend the data quality principles to the context of Semantic Web. Based on our extensive industrial experience in data integration, we identify five main classes suited for data quality in Semantic Web. For each class, we list the principles that are involved at all stages of the data management process. Following these principles will provide a sound basis for better decision-making within organizations and will maximize long-term data integration and interoperability.

title: Tests rapides à orientation diagnostique de la grippe en Ehpad : entre engouement initial et déception finale

description: Objectif. Entre 2012 et 2016, une expérimentation a été menée en Franche-Comté, afin de faciliter le diagnostic de la grippe dans les établissements d’hébergement pour personnes âgées dépendantes (Ehpad). Cette expérimentation reposait sur la mise à disposition gratuite de tests rapides à orientation diagnostique (Trod) de la grippe. L’objectif de cette étude est de dresser un bilan de ces 4 années d’expérimentation. Méthode. L’évaluation a reposé sur le suivi de l’utilisation des Trod mis à disposition de 115 Ehpad et sur les appréciations d’un échantillon aléatoire de ces établissements. Résultats. Au cours de la période, 147 (21 %) des 700 Trod distribués ont été utilisés. Cette utilisation a été maximale pour la saison 2014-2015 avec confirmation diagnostique de 18 cas. Seuls 15,5 % des Ehpad interrogés (n = 9) ont répondu au sondage, la majorité d’entre eux (n = 7) déclarant que l’expérimentation n’avait pas modifié la mise en place des mesures barrières et les prescriptions d’antiviraux. Conclusion. Du fait d’un faible recours aux Trod, il a été décidé de ne pas poursuivre l’expérimentation. Notre expérience ne plaide pas pour leur mise à disposition – même gratuite – dans les Ehpad. Les stratégies de prévention grippale doivent inclure principalement la promotion de la vaccination des résidents et des professionnels, et la mise en œuvre rapide des mesures barrières.

description: Driving autonomously requires highly accurate positioning. Therefore, alternative positioning systems to GPS are required especially to increase the accuracy, and to have a complementary data source in areas where GPS is not available. As more and more on-board sensors are used for safety reasons, information gathered about their environment can be used for positioning based on relative measurements to landmarks along the road. This paper investigates the accuracy potential of positioning using a stereo camera system and landmark maps. Therefore, we simulated several stereo camera systems with variable opening angle and base length to compute the positioning accuracy in a test area. In the first step, localization was calculated based on single positions, in the second step we used a Kalman filter additionally. While positioning in the first case was not successful along the entire trajectory, the Kalman filter led to far better results.

description: The role of the acoustic continuum associated with compact sources in the Sun's interior wave field is explored for a simple polytropic model. The continuum produces a near-field acoustic structure -- the so-called `acoustic jacket' -- that cannot be represented by a superposition of discrete normal modes. Particular attention is paid to monochromatic point sources of various frequency and depth, and to the surface velocity power that results, both in the discrete f- and p-mode spectrum and in the continuum. It is shown that a major effect of the continuum is to heal the surface wave field produced by compact sources, and therefore to hide them from view. It is found that the continuous spectrum is not a significant contributor to observable inter-ridge seismic power.
