description: A new approach for the development of thermoelectric materials, which focuses on a high-power factor instead of a large figure of merit zT, has drawn attention in recent years. In this context, the thermoelectric properties of Cu-Ni-based alloys with a very high electrical conductivity, a moderate Seebeck coefficient, and therefore a high power factor are presented as promising low-cost alternative materials for applications aiming to have a high electrical power output. The Cu-Ni-based alloys are prepared via an arc melting process of metallic nanopowders. The heavy elements tin and tungsten are chosen for alloying to further improve the power factor while simultaneously reducing the high thermal conductivity of the resulting metal alloy, which also has a positive effect on the zT value. Overall, the samples prepared with low amounts of Sn and W show an increase in the power factor and figure of merit zT compared to the pure Cu-Ni alloy. These results demonstrate the potential of these often overlooked metal alloys and the utilization of nanopowders for thermoelectric energy conversion.
title: Analyse préliminaire des risques appliquée au parcours du patient nécessitant un examen d’endoscopie digestive programmé sous anesthésie générale

description: L’endoscopie est une activité médicotechnique complexe, pluridisciplinaire et nécessitant une coordination importante entre les différents professionnels. Dans le contexte actuel de sécurisation des soins, un travail d’analyse préliminaire de risques a été réalisé dans un établissement de santé sur le parcours des patients nécessitant un examen endoscopique programmé sous anesthésie générale en hépato-gastroentérologie. Des observations dans les unités de soins et la synthèse des évènements indésirables signalés ont permis la définition du processus et des dangers génériques associés, ainsi que la construction de la cartographie des situations dangereuses et du tableau des scénarios. Ces différents éléments ont été analysés et validés par un groupe de travail pluriprofessionnel, et une criticité a été estimée pour chaque scénario afin d’identifier les risques prioritaires et déterminer des actions d’amélioration. La mise en œuvre de 5 axes d’amélioration a permis de maîtriser l’ensemble des risques jugés inacceptables. Une évaluation des risques résiduels ainsi que le suivi à moyen/long terme des actions mises en œuvre devront être mis en place. Cette étude a permis aux professionnels de santé d’identifier les risques liés à leur activité, à partir d’une démarche collective pluriprofessionnelle conforme aux exigences réglementaires d’amélioration de la qualité et de la sécurité des soins.

description: We continue the development of the homological theory of quantum general linear groups previously considered by the first author. The development is used to transfer information to the representation theory of quantised Schur algebras. The acyclicity of induction from some rank-one modules for quantised Borel-Schur subalgebras is deduced. This is used to prove the exactness of the complexes recently constructed by Boltje and Maisch, giving resolutions of the co-Specht modules for Hecke algebras.

description: Chronic antibody-mediated rejection (AMR) is a key limiting factor for the clinical outcome of a kidney transplantation (Ktx), where early diagnosis and therapeutic intervention is needed. This study describes the identification of the biomarker CXC-motif chemokine ligand (CXCL) 9 as an indicator for AMR and presents a new aptamer-antibody-hybrid lateral flow assay (hybrid-LFA) for detection in urine. Biomarker evaluation included two independent cohorts of kidney transplant recipients (KTRs) from a protocol biopsy program and used subgroup comparisons according to BANFF-classifications. Plasma, urine and biopsy lysate samples were analyzed with a Luminex-based multiplex assay. The CXCL9-specific hybrid-LFA was developed based upon a specific rat antibody immobilized on a nitrocellulose-membrane and the coupling of a CXCL9-binding aptamer to gold nanoparticles. LFA performance was assessed according to receiver operating characteristic (ROC) analysis. Among 15 high-scored biomarkers according to a neural network analysis, significantly higher levels of CXCL9 were found in plasma and urine and biopsy lysates of KTRs with biopsy-proven AMR. The newly developed hybrid-LFA reached a sensitivity and specificity of 71% and an AUC of 0.79 for CXCL9. This point-of-care-test (POCT) improves early diagnosis-making in AMR after Ktx, especially in KTRs with undetermined status of donor-specific HLA-antibodies.

description: We report pronounced modifications of electronic and vibrational properties induced in FeO by cation vacancies, obtained within density functional theory incorporating strong local Coulomb interactions at Fe atoms. The insulating gap of FeO is reduced by about 50% due to unoccupied electronic bands introduced by trivalent Fe ions stabilized by cation vacancies. The changes in the electronic structure along with atomic displacements induced by cation vacancies affect strongly phonon dispersions via modified force constants, including those at atoms beyond nearest neighbors of defects. We demonstrate that theoretical phonon dispersions and their densities of states reproduce the results of inelastic neutron and nuclear resonant x-ray scattering experiments \emph{only} when Fe vacancies and Coulomb interaction $U$ are both included explicitly in \emph{ab initio} simulations, which also suggests that the electron-phonon coupling in FeO is strong.

title: Sécurisation de l’administration des médicaments en psychiatrie : la tâche unique est-elle une solution ?
Creators: name: Motyka, Sabine
Publisher: name: Health & Co
Year: 2019

description: Introduction. L’administration des médicaments est une étape critique de la prise en charge médicamenteuse (PECM). La réduction des interruptions des tâches (IT) est donc un enjeu sécuritaire. Ainsi un protocole, dit de la tâche unique, a été mis en place dans une de nos unités de soins psychiatriques. Les objectifs de ce travail étaient d’établir un état des lieux des IT dans cette unité de soins et d’y évaluer l’impact de la tâche unique. Matériels et méthode. La tâche unique combine plusieurs méthodes visant à réduire les IT lors de l’administration des médicaments. Une étude prospective a été menée en deux périodes successives : 12 jours avant et 11 jours après la mise en place de la tâche unique. Durant celles-ci, un formulaire permettant de comptabiliser et de caractériser les IT a été rempli. Un mois après, un questionnaire de satisfaction a été complété par les infirmiers. Résultats. Au total, 100 IT ont été notifiées, dont 84 en première période. Au cours de cette dernière, le patient a été identifié comme première source d’IT. Entre les deux périodes, le nombre d’IT a été réduit par 5. D'après le questionnaire de satisfaction, 7 infirmiers sur 10 étaient satisfaits de la mise en place de la tâche unique. Conclusion. Cette étude a permis d’identifier le patient comme première source d’IT dans notre établissement. De plus, elle démontre l’impact positif de la tâche unique en matière de réduction des IT et de satisfaction des soignants, ce qui en fait un outil de sécurisation de la PECM en établissement psychiatrique.

description: La sécurisation de la prise en charge médicamenteuse est l’un des axes prioritaires inscrits dans le plan stratégique de l’Assistance publique-Hôpitaux de Paris (AP-HP). L’ensemble des types de prise en charge sont représentés dans ce centre hospitalier universitaire (CHU), avec environ 23 000 lits d’hospitalisation. Son département management qualité-risques a saisi l’opportunité de cette démarche institutionnelle pour tester un dispositif pédagogique auprès d’étudiants en formation initiale. Deux instituts de formation de l’AP-HP ont accepté de participer à cette expérimentation : le Centre de formation des préparateurs en pharmacie hospitalière (CFPPH) et l’institut de formation en soins infirmiers (Ifsi) de Picpus. Le dispositif pédagogique, combinant formation et mises en situation, a été évalué par les étudiants, via un questionnaire, afin d’apprécier leurs retours d’expérience. L’évaluation portait sur la perception du dispositif d’accompagnement mis en place, et cherchait à objectiver l’acquisition de connaissances sur les risques liés à la prise en charge médicamenteuse du patient, de l’identification des médicaments jusqu’à leur administration, ainsi que sur la méthodologie de l’audit interne. Sur les 59 étudiants préparateurs en pharmacie hospitalière (PPH), 44 ont répondu, et sur les 100 élèves en soins infirmiers (ESI), 56 ont répondu, soit 100 répondants. Les résultats montrent que près de 72% des répondants, étudiants PPH et ESI confondus, ont apprécié les contenus de ce dispositif pédagogique.

description: Contexte et objectif. La détection et le signalement des événements indésirables associés aux soins (EIAS) occupent une place primordiale dans la gestion des risques. Les programmes nationaux promeuvent les méthodes d’apprentissage par la simulation et le retour d’expérience pour faire progresser la sécurité et la qualité des soins. En ce sens, le centre hospitalier régional universitaire de Nancy a souhaité mettre en œuvre un outil ludique et pédagogique pour sensibiliser les étudiants à la gestion des risques : la chambre des erreurs (CDE) multivigilance. Méthode. Un groupe de travail avec des enseignants référents a été constitué pour élaborer un scénario regroupant 14 EIAS. La CDE a été déployée au sein de six écoles hospitalières paramédicales. Résultats. L’enquête au sein de la CDE a été menée par 131 étudiants et a été très appréciée (95% de satisfaction totale). En moyenne, ils ont découvert 54% des erreurs. Le pourcentage d’erreurs détectées n’était pas différent selon la formation initiale des étudiants. L’analyse des erreurs prévues et non prévues dans le scénario a fait émerger des perspectives d’action pour leur formation. Conclusion. La CDE est un outil riche qui permet de faire un état des lieux des connaissances des étudiants, et permet également l’acquisition de nouvelles connaissances et compétences concourant à améliorer la culture qualité et sécurité des soins.

description: We study circular nanomechanical graphene resonators by means of continuum elasticity theory, treating them as membranes. We derive dynamic equations for the flexural mode amplitudes. Due to geometrical nonlinearity these can be modeled by coupled Duffing equations. By solving the Airy stress problem we obtain analytic expressions for eigenfrequencies and nonlinear coefficients as functions of radius, suspension height, initial tension, back-gate voltage and elastic constants, which we compare with finite element simulations. Using perturbation theory, we show that it is necessary to include the effects of the non-uniform stress distribution for finite deflections. This correctly reproduces the spectrum and frequency tuning of the resonator, including frequency crossings.

description: We present an all-polymer optical humidity sensor, based on a 1 mm plastic optical fiber (POF) with a U-bend, cladded with poly(N,N-dimethylacrylamide) (PDMAA) in the sensing region. The cladding changes its scattering properties on absorption of environmental humidity, thus modulating the transmitted optical power through the sensor. We explain the working principle of the sensor and show experimental results regarding scattering behavior of the cladding material and sensitivity to sudden humidity changes. We also propose a planar layout suitable for application to a hot embossing or lamination process for large-scale fabrication.

description: The investigation of the Earth ionosphere both in a quiet and a disturbed states is still desirable. Despite recent progress in its modeling and in estimating the electron concentration along the line of sight by GPS signals, the impact of the disturbed ionosphere and magnetic field on the wave propagation still remains not sufficiently understood. This is due to lack of information on the polarization of GPS signals, and due to poorly conditioned models of the ionosphere at high altitudes and strong perturbations. In this article we consider a possibility of using the data of pulsar radio emission, along with the traditional GPS system data, for the vertical and oblique sounding of the ionosphere. This approach also allows to monitor parameters of the propagation medium, such as the dispersion measure and the rotation measure using changes of the polarization between pulses. By using a selected pulsar constellation it is possible to increase the number of directions in which parameters of the ionosphere and the magnetic field can be estimated.

Les revues de mortalité et de morbidité (RMM) et les comités de retour d’expérience (Crex) sont deux méthodes permettant de gérer la sécurité des patients dans les équipes soignantes. L’objectif de cette étude était de comparer les perceptions des professionnels de santé utilisant conjointement l’une et l’autre de ces deux méthodes et de déterminer l’impact de cette double utilisation. Méthodes. Nous avons réalisé une étude qualitative basée sur des entretiens semi-directifs auprès de 14 professionnels de santé exerçant dans des services hospitaliers disposant de RMM et de Crex. Résultats. Les deux outils étaient appréciés par les soignants et perçus comme complémentaires. Les Crex étaient perçus comme favorisant la pluridisciplinarité et encourageant la pratique de l’analyse systémique des événements indésirables, permettant d’améliorer l’organisation des équipes. Les RMM, plutôt tournées vers les médecins et à la méthodologie moins standardisée, semblaient plus centrées sur l’évaluation des pratiques professionnelles, encourageant la formation continue des professionnels. Il y avait peu de transfert méthodologique d’un outil à l’autre. Enfin, les soignants ont décrit des faiblesses similaires pour les deux outils (manque de temps, de valorisation et de communication autour des outils et des actions menées). Conclusions. Les Crex et les RMM sont deux outils complémentaires concourant à l’amélioration de l’organisation et des pratiques des équipes soignantes. Ces deux outils connaissent cependant des limites communes, inhérentes au manque de temps des professionnels et aux leviers d’action insuffisants dont disposent les équipes participant à ces dispositifs.

description: We performed Cathodoluminescence (CL) spectroscopy and imaging in a high resolution scanning electron microscope to locally and selectively excite and investigate the plasmonic property of a multibranched gold nanostar on silicon substrate. This method allows us to map the local density of optical states from the nanostar with a spatial resolution down to a few nanometers. We resolve both in spatial and spectral domain, different plasmon modes associated with the nanostar. Finite- difference time-domain (FDTD) numerical simulations are performed to support the experimental observations. We investigate the effect of substrate on the plasmonic property of these complex shaped nanostars. The powerful CL-FDTD combination helps us to understand the effect of the substrate on plasmonic response of branched nanoparticles.

description: Automated Fiber Placement (AFP) processes are commonly deployed in manufacturing of lightweight structures made of carbon fibre reinforced polymer. In general, AFP is connected to individual manufacturing knowledge during process planning and time consuming manual quality inspections. In both cases, automatic solutions provide a high economic potential. Therefore, a machine learning approach for planning, optimizing and inspection of AFP processes is presented. Process data from planning, CNC and online process monitoring is aggregated for the documentation of the part specific manufacturing history and the automated generation of manufacturing knowledge. Within this approach a complete automation of data capturing, data storing, modeling and optimizing is achieved.

Determining Heating Rates in Reconnection Formed Flare Loops of the M8.0 Flare on 2005 May 13

description: We analyze and model an M8.0 flare on 2005 May 13 observed by TRACE and RHESSI to determine the energy release rate from magnetic reconnection that forms and heats numerous flare loops. The flare exhibits two ribbons in UV 1600 Å emission. Analysis shows that the UV light curve at each flaring pixel rises impulsively within a few minutes, and decays slowly with a timescale >10 min. Since the lower atmosphere (transition region and chromosphere) responds to energy deposit nearly instantaneously, the rapid UV brightening is thought to reflect the energy release process in the newly formed flare loop rooted at the footpoint. We utilize spatially resolved (down to 1 arcsec) UV light curves and thick-target hard X-ray emission to construct heating functions of a few thousand flare loops anchored at UV foot points, and compute plasma evolution in these loops using the EBTEL model. The modeled coronal temperatures and densities of these flare loops are used to calculate synthetic soft X-ray spectra and light curves, which compare favorably with those observed by RHESSI and GOES/XRS. The time-dependent transition region DEM for each loop during its decay phase is also computed with a simplified model and used to calculate the optically-thin C IV line emission, which dominates the UV 1600 Å bandpass during the flare. The computed C IV line emission decays at the same rate as observed. This study presents a method to constrain heating of reconnection-formed flare loops using all available observables independently, and provides insight into the physics of energy release and plasma heating during the flare. With this method, the lower limit of the total energy used to heat the flare loops in this event is estimated to be 1.22e31 ergs, of which only 1.9e30 ergs is carried by beam-driven upflows during the impulsive phase, suggesting that the coronal plasmas are predominantly heated in situ.

description: Background: Among other causes the long-term result of hip prostheses in dogs is determined by aseptic loosening. A prevention of prosthesis complications can be achieved by an optimization of the tribological system which finally results in improved implant duration. In this context a computerized model for the calculation of hip joint loadings during different motions would be of benefit. In a first step in the development of such an inverse dynamic multi-body simulation (MBS-) model we here present the setup of a canine hind limb model applicable for the calculation of ground reaction forces. Methods: The anatomical geometries of the MBS-model have been established using computer tomography- (CT-) and magnetic resonance imaging- (MRI-) data. The CT-data were collected from the pelvis, femora, tibiae and pads of a mixed-breed adult dog. Geometric information about 22 muscles of the pelvic extremity of 4 mixed-breed adult dogs was determined using MRI. Kinematic and kinetic data obtained by motion analysis of a clinically healthy dog during a gait cycle (1 m/s) on an instrumented treadmill were used to drive the model in the multi-body simulation. Results and Discussion: As a result the vertical ground reaction forces (z-direction) calculated by the MBS-system show a maximum deviation of 1.75%BW for the left and 4.65%BW for the right hind limb from the treadmill measurements. The calculated peak ground reaction forces in z- and y-direction were found to be comparable to the treadmill measurements, whereas the curve characteristics of the forces in y-direction were not in complete alignment. Conclusion: In conclusion, it could be demonstrated that the developed MBS-model is suitable for simulating ground reaction forces of dogs during walking. In forthcoming investigations the model will be developed further for the calculation of forces and moments acting on the hip joint during different movements, which can be of help in context with the in silico development and testing of hip prostheses.

description: Background: Bioabsorbable implants are not widely used in spine surgery. This study investigated the clinical and radiological findings after anterior cervical discectomy and fusion (ACDF) in an ovine animal model with an experimental bioabsorbable cage consisting of magnesium and polymer (poly-ε-caprolactone, PCL) in comparison to a tricortical bone graft as the gold standard procedure. Materials and Methods: 24 full-grown sheep had ACDF of C3/4 and C5/6 with an experimental bioabsorbable implant (magnesium and PCL) in one level and an autologous tricortical bone graft in the second level. The sheep were divided into 4 groups (6 sheep each). After 3, 6, 12, or 24 weeks postoperatively, the cervical spines were harvested and conventional x-rays of each operated segment were conducted. The progress of interbody fusion was classified according to a three-point scoring system. Results: There were no operation related complications except for one intraoperative fracture of the anterior superior iliac spine and two cases of screw loosening and sinking, respectively. In particular, no vascular, neurologic, wound healing or infectious problems were observed. According to the time of follow-up, both interbody fusion devices showed similar behaviour with increasing intervertebral osseointegration and complete arthrodesis in 10 of 12 (83.3%) motion segments after 24 weeks. Conclusions: The bioabsorbable magnesium-PCL cage used in this experimental animal study showed clinically no signs of incompatibility such as infectious or wound healing problems. The radiographic results regarding the osseointegration are comparable between the cage and the bone graft group.

description: We conducted Very Long Baseline Array (VLBA) observations of seven nearby narrow-line Seyfert 1 (NLS1) galaxies at 1.7 GHz (18cm) with milli-arcsecond resolution. This is the first systematic very long baseline interferometry (VLBI) study focusing on the central parsec-scale regions of radio-quiet NLS1s. Five of the seven were detected at a brightness temperature of >~5x10^6 K and contain radio cores with high brightness temperatures of >6x10^7 K, indicating a nonthermal process driven by jet-producing central engines as is observed in radio-loud NLS1s and other active galactic nucleus (AGN) classes. VLBA images of MRK 1239, MRK 705, and MRK 766 exhibit parsec-scale jets with clear linear structures. A large portion of the radio power comes from diffuse emission components that are distributed within the nuclear regions (

description: We provide an algorithm based on weighted-ensemble (WE) methods, to accurately sample systems at steady state. Applying our method to different one- and two-dimensional models, we succeed to calculate steady state probabilities of order $10^{-300}$ and reproduce Arrhenius law for rates of order $10^{-280}$. Special attention is payed to the simulation of non-potential systems where no detailed balance assumption exists. For this large class of stochastic systems, the stationary probability distribution density is often unknown and cannot be used as preknowledge during the simulation. We compare the algorithms efficiency with standard Brownian dynamics simulations and other WE methods.

description: Background: Studying mechanical properties of canine trabecular bone is important for a better understanding of fracture mechanics or bone disorders and is also needed for numerical simulation of canine femora. No detailed data about elastic moduli and degrees of anisotropy of canine femoral trabecular bone has been published so far, hence the purpose of this study was to measure the elastic modulus of trabecular bone in canine femoral heads by ultrasound testing and to assess whether assuming isotropy of the cancellous bone in femoral heads in dogs is a valid simplification.

description: Background: The use of artificial endoprostheses has become a routine procedure for knee and hip joints while ankle arthritis has traditionally been treated by means of arthrodesis. Due to its advantages, the implantation of endoprostheses is constantly increasing. While finite element analyses (FEA) of strain-adaptive bone remodelling have been carried out for the hip joint in previous studies, to our knowledge there are no investigations that have considered remodelling processes of the ankle joint. In order to evaluate and optimise new generation implants of the ankle joint, as well as to gain additional knowledge regarding the biomechanics, strain-adaptive bone remodelling has been calculated separately for the tibia and the talus after providing them with an implant. Methods: FE models of the bone-implant assembly for both the tibia and the talus have been developed. Bone characteristics such as the density distribution have been applied corresponding to CT scans. A force of 5,200 N, which corresponds to the compression force during normal walking of a person with a weight of 100 kg according to Stauffer et al., has been used in the simulation. The bone adaptation law, previously developed by our research team, has been used for the calculation of the remodelling processes. Results: A total bone mass loss of 2% in the tibia and 13% in the talus was calculated. The greater decline of density in the talus is due to its smaller size compared to the relatively large implant dimensions causing remodelling processes in the whole bone tissue. In the tibia, bone remodelling processes are only calculated in areas adjacent to the implant. Thus, a smaller bone mass loss than in the talus can be expected. There is a high agreement between the simulation results in the distal tibia and the literature regarding. Conclusions: In this study, strain-adaptive bone remodelling processes are simulated using the FE method. The results contribute to a better understanding of the biomechanical behaviour of the ankle joint and hence are useful for the optimisation of the implant geometry in the future.

description: Background: There are several numerical investigations on bone remodelling after total hip arthroplasty (THA) on the basis of the finite element analysis (FEA). For such computations certain boundary conditions have to be defined. The authors chose a maximum of three static load situations, usually taken from the gait cycle because this is the most frequent dynamic activity of a patient after THA. Materials and methods: The numerical study presented here investigates whether it is useful to consider only one static load situation of the gait cycle in the FE calculation of the bone remodelling. For this purpose, 5 different loading cases were examined in order to determine their influence on the change in the physiological load distribution within the femur and on the resulting strain-adaptive bone remodelling. First, four different static loading cases at 25%, 45%, 65% and 85% of the gait cycle, respectively, and then the whole gait cycle in a loading regime were examined in order to regard all the different loadings of the cycle in the simulation. Results: The computed evolution of the apparent bone density (ABD) and the calculated mass losses in the periprosthetic femur show that the simulation results are highly dependent on the chosen boundary conditions. Conclusion: These numerical investigations prove that a static load situation is insufficient for representing the whole gait cycle. This causes severe deviations in the FE calculation of the bone remodelling. However, accompanying clinical examinations are necessary to calibrate the bone adaptation law and thus to validate the FE calculations.

description: We extend the recently introduced continuous matrix product state (cMPS) variational class to the setting of (1+1)-dimensional relativistic quantum field theories. This allows one to overcome the difficulties highlighted by Feynman concerning the variational procedure applied to relativistic theories, and provides a new way to regularize quantum field theories. A fermionic version of the continuous matrix product state is introduced which is manifestly free from fermion doubling and sign problems. We illustrate the power of the formalism with the simulation of free massive Dirac fermions, the Gross-Neveu model, and the Casimir effect. We find that cMPS can capture chiral symmetry breaking with absolute scaling of the chiral parameter, and that boundary effects can be accommodated with modest computational effort.
