title: Peut-on utiliser le système d’information hospitalier pour la surveillance des infections du site opératoire ?
Creators: name: Pina, Patrick
Publisher: name: Health & Co
Year: 2018

description: La surveillance des infections du site opératoire (ISO) est un axe important du contrôle des infections nosocomiales mais demande un investissement pluridisciplinaire coûteux en temps. Objectif. Le but de notre travail a été d’évaluer les performances du programme de médicalisation des systèmes d’information (PMSI) pour identifier les ISO et faciliter leur surveillance. Matériel et méthode. L’étude a porté sur les principales chirurgies digestives, orthopédiques et obstétricales. Les indices de performance de la détection des ISO par les codes PMSI (T814, T845, T846, T847, O85, O860 et O864) seuls ou combinés ont été mesurés par rapport à la méthode de référence. Résultats. Parmi les 3 488 interventions étudiées, 98 ISO ont été identifiées. Celles associées aux prothèses de hanche sont toutes détectées par le codage PMSI (valeur prédictive négative [VPN] de 100 % - valeur prédictive positive [VPP] de 100 %). Les ISO associées aux autres chirurgies sont moins constamment repérées (VPN de 98,6 %, 99,2 % et 98,8 % respectivement pour les chirurgies digestives, les ostéosynthèses et les césariennes). Dans ces chirurgies, les faux positifs sont des ISO survenues pour d’autres interventions chez des patients bénéficiant de chirurgies multiples. Les faux négatifs sont le plus souvent liés au diagnostic de l’ISO fait en consultation et donc non codé par le PMSI. Conclusion. Dans notre expérience, les données du PMSI ne peuvent pas être utilisées seules dans la surveillance des ISO mais peuvent servir à les repérer et à limiter le nombre de dossiers patients à examiner.

description: We report the observation of strong third harmonic generation from a macroscopic array of aligned ultralong single-wall carbon nanotubes (SWCNTs) with intense midinfrared radiation. Through power-dependent experiments, we determined the absolute value of the third-order nonlinear optical susceptibility, $χ^{(3)}$, of our SWCNT film to be 5.53 $\times$ 10$^{-12}$ esu, three orders of magnitude larger than that of the fused silica reference we used. Taking account of the filling factor of 8.75% for our SWCNT film, we estimate a $χ^{(3)}$ of 6.32 $\times$ 10$^{-11}$ esu for a fully dense film. Furthermore, through polarization-dependent experiments, we extracted all the nonzero elements of the $χ^{(3)}$ tensor, determining the magnitude of the weaker tensor elements to be $\sim$1/6 of that of the dominant $χ^{(3)}_{zzzz}$ component.

description: In recent years it has become clear that the vertical structure of disk galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure of extra-planar gas has been a focus of research. The Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) survey aims to provide a census on the rate of cold neutral gas accretion in nearby galaxies as well as a statistically significant set of galaxies that can be investigated for their extra-planar gas properties. In order to better understand the the vertical structure of the neutral hydrogen in the two edge-on HALOGAS galaxies NGC 5023 and UGC 2082 we construct detailed tilted ring models. The addition of distortions resembling arcs or spiral arms significantly improves the fit of the models to these galaxies. In the case of UGC 2082 no vertical gradient in rotational velocity is required in either symmetric models nor non-symmetric models to match the observations. The best fitting model features two arcs of large vertical extent that may be due to accretion. In the case of NGC 5023 a vertical gradient is required in symmetric models (dV/dz =$-14.9\pm3.8$ km s$^{-1}$ kpc$^{-1}$) and its magnitude is significantly lowered when non-symmetric models are considered (dV/dz =$-9.4\pm3.8$ km s$^{-1}$ kpc$^{-1}$). Additionally it is shown that the underlying disk of NGC 5023 can be made symmetric, in all parameters except the warp, in non-symmetric models. In comparison to the "classical" modeling these models fit the data significantly better with a limited addition of free parameters.

description: L’équipe opérationnelle d’hygiène (EOH) a travaillé avec le service d’information médicale (SIM) et la direction du système d’information, afin de créer un questionnaire « précautions complémentaires » (PC) dans le dossier informatisé patient et, à partir de cela, d’ajouter des codes dans le programme de médicalisation des systèmes d’information (PMSI). Objectifs. Il s’agit de décrire le recueil de ce questionnaire et de rapporter son impact sur la valorisation des séjours. Méthode. Le questionnaire est complété par l’EOH pour chaque indication de mise en place de PC. Le type de PC, son indication, le type de micro-organisme, la situation de portage sain ou d’infection et les résistances bactériennes sont recueillis ainsi que les codes Classification internationale des maladies 10e révision (CIM-10) correspondants pour le recueil dans le PMSI. Une analyse descriptive des questionnaires PC, du codage dans le PMSI et de la valorisation des séjours a été réalisée entre octobre 2015 et octobre 2016. Résultats. Au total, 2 598 questionnaires ont été remplis par l’EOH, dans 99,5 % des cas pour des PC contact. Le codage dans le PMSI des informations recueillies dans l’ensemble des questionnaires a permis d’augmenter la valorisation des séjours dans 62 cas. De plus, le médecin du SIM a pu repérer et corriger 24 séjours pour lesquels les codages proposés par l’EOH n’avaient pas été validés, soit un gain de valorisation de plus de 50 000 €. Conclusion. Au-delà de la collaboration avec le SIM, qui permet d’assurer une plus juste valorisation des séjours ; la création d’un questionnaire PC a plusieurs intérêts pour l’EOH, en particulier la traçabilité d’une partie de ses activités.

description: Class-D amplifiers are suiteble for amplification of audio signals. One argument is their high efficiency of 90% and more. Today most of the audio signals are stored or transmitted in digital form. A digitally controlled Class-D amplifier can be directly driven with coded (modulated) data. No separate D/A conversion is needed. Classical modulation schemes like Pulse-Width-Modulation (PWM) cause aliasing. So a very high switching rate is required to minimize the aliasing component within the signal band. This paper shows a first implementation of the new SB-ZePoC modulation scheme (Zero Position Coding with Separated Baseband), which allows the generation of a binary signal with separated baseband. Therefore Class-D amplifiers using SB-ZePoC can be run with very low switching rates. Some benefits and problems in the design process because of low switching rates will be discussed. Measurements of a real-time implementation will be presented.

description: By the rising complexity and miniaturisation of the device's dimensions, the density of the conductors increases considerably. Referring to this, locally transient interactions between single physical values become apparent. Therefore, for the investigation and optimisation of integrated circuits it is essential to develop suitable models and simulation surroundings which allow for memory and timeefficient calculation of the behaviour. By means of the dynamic reconstruction theory and the radial basis functions nets the so-called black box models are provided. The description of black box models is derived from the input and output behaviour or so-called time series of a dynamic system. Concerning the time series, the black box model adapts its parameters via the extended Kalman filter. This paper provides a modelling approach that enables fast and efficient simulations.
title: Antibioprophylaxie et césarienne : analyse des modalités d’administration dans 30 maternités
Creators: name: Valdeyron, Marie-Laure
Publisher: name: Health & Co
Year: 2018

description: Si l’antibioprophylaxie est largement recommandée pour les césariennes, ses modalités d’administration ne sont pas complètement consensuelles. Objectif. L’objectif de cette étude était de décrire les pratiques d’antibioprophylaxie dans un ensemble de maternités volontaires, avec un intérêt particulier pour la disponibilité d’un protocole, pour le moment de l’injection, et pour le doublement de la dose d’antibiotique lorsque l’indice de masse corporelle (IMC) est supérieur à 35 kg/m2. Méthode. Le recueil d’informations a été réalisé en 2015, par questionnaires. Résultats. Trente maternités et 282 anesthésistes ont participé à l’enquête. Les protocoles sont présents dans toutes ces maternités et 40 % d’entre eux mentionnent le doublement de la dose d’antibiotique si l’IMC de la patiente est > 35 kg/m2. La majorité des protocoles (93,3 %) préconisent l’injection de l’antibiotique après clampage du cordon, et la céfazoline est utilisée dans 29 maternités sur 30. Les anesthésistes déclarent réaliser l’injection après clampage du cordon pour 83,4 % d’entre eux, et plus rarement 15 à 60 min avant l’incision (10,5 %), ou à l’incision du site opératoire (7,9 %). Seule la moitié des anesthésistes déclarent doubler la dose si l’IMC de la patiente est > 35 kg/m2. Les résultats d’études publiées ne permettent pas de trancher sur le moment de l’antibioprophylaxie. Conclusion. Cette étude a montré que deux ajustements de pratiques sont nécessaires dans les maternités y ayant participé : le doublement de la dose d’antibiotique si la patiente est obèse, et son injection 30 min avant incision ; ils nécessiteraient une nouvelle enquête pour s’assurer qu’ils sont pris en compte.

description: Developing powerful hand-held drift tube ion mobility spectrometers (IMS) requires small, lightweight drift tubes with high analytical performance. In this work, we present an easy-to-manufacture, miniaturized drift tube ion mobility spectrometer, which is manufactured from polyether ether ketone, stainless steel foils and printed circuit boards. It is possible to operate the drift tube IMS with a radioactive 3H ionization source or a non-radioactive X-ray ionization source with 3 kV acceleration voltage. The drift tube design provides high resolving power of Rp = 63 at a drift length of just 40 mm, 15 mm × 15 mm in cross-section (outer dimensions) and a drift voltage of 2.5 kV. The limits of detection for less than one second of averaging are 40 pptv for dimethyl-methylphosphonate and 30 pptv for methyl salicylate. For demonstration, the miniaturized drift tube IMS is integrated into a stand-alone battery-powered mobile device, including a closed gas-loop, high performance driver electronics and wireless data transmission. In a proof-of-concept study, this device was tested in an international field evaluation exercise to detect the release of a volatile, hazardous substance inside a large entry hall.
Probing Two-Field Open Inflation by Resonant Signals in Correlation Functions

description: We derive oscillatory signals in correlation functions in two-field open inflation by means of the in-in formalism; such signatures are caused by resonances between oscillations in the tunnelling field and fluctuations in the inflaton during the curvature dominated, intermediate and subsequent inflationary regime. While amplitudes are model-dependent, we find distinct oscillations in the power and bi-spectrum that can act as a direct probe of the curvature dominated phase and thus, indirectly, strengthen the claim of the string landscape if they were observed. We comment on the prospects of detecting these tell-tale signs in current experiments, which is challenging, but not impossible. At the technical level, we pay special attention to the applicability conditions for truncation fluctuations to the light (inflaton) field and derive upper limits on the oscillation amplitude of the heavy field. A violation of these bounds requires a multi-field analysis at the perturbed level.

The field configurations of the theories considered may have the topology of skyrmions, vortices or monopoles, although we focus our detailed investigations on skyrmions. The resulting Lifshitz field theories have a BPS bound and exact soliton solutions saturating the bound, as well as time-dependent topological Q-ball solutions. Finally, we investigate the U(1) gauged versions of the Lifshitz field theories coupled to a Chern-Simons gauge field, where the BPS bound and soliton solutions saturating the bound continue to exist.

description: Due to growing challenges regarding crash-performance, CO2 emission as well as increasing demand for lightweight construction, hot metal forming of car body parts has risen to one of the most important technologies for saving weight of a car body. During hot forming shaped blanks of steel are heated and austenitized at around 950°C and subsequently quenched for martensitic formation. Currently the heating is realized in roller hearth furnaces which allow only a slow heating and, therefore, a limited production rate. Induction heating of the blanks offers a big potential to increase the production rate dramatically and also to improve the energy efficiency. Only due to the fact, that the heated blanks typically are already pre-shaped with holes and cut-outs induction heating becomes a very complex task. The paper compares different possible induction heating methods (longitudinal heating, transverse flux heating, single stage induction heating, hybrid heating by induction and conventional heating). For the case of single stage induction heating a detailed numerical and experimental investigation in the frame of a recently completed research project is presented.

description: By sheet metal forming processes the forming limits and part characteristics are defined through the process specific loads. In deep drawing processes the maximum deep draw ratios as well as the springback behaviour of the metal parts are depending on the stress distribution in the part material during the forming process. While exceeding the load limits, a failure in the material occurs, which can be avoided by additional force transmission activated in the deep drawing process before the forming limit of material is achieved. This contribution deals with numerical investigation of process effect caused by additional force transmission regarding the extension of the process limits. Here, the steel material HCT 600X+Z (1.0941) in thickness s 0 = 1.0 mm is analyzed numerically using the anisotropic model Hill48. This model is validated by the means of cup test by Swift. Both, the FEA of conventional and forming process with additional force transmission are carried out. The numerical results are compared with reference geometry of rectangle cup.

description: Detection of a signal hidden by noise within a time series is an important problem in many astronomical searches, i.e. for light curves containing the contributions of periodic/semi-periodic components due to rotating objects and all other astrophysical time-dependent phenomena. One of the most popular tools for use in such studies is the "periodogram", whose use in an astronomical context is often not trivial. The "optimal" statistical properties of the periodogram are lost in the case of irregular sampling of signals, which is a common situation in astronomical experiments. Parts of these properties are recovered by the "Lomb-Scargle" (LS) technique, but at the price of theoretical difficulties, that can make its use unclear, and of algorithms that require the development of dedicated software if a fast implementation is necessary. Such problems would be irrelevant if the LS periodogram could be used to significantly improve the results obtained by approximated but simpler techniques. In this work we show that in many astronomical applications simpler techniques provide results similar to those obtainable with the LS periodogram. The meaning of the "Nyquist frequency" is also discussed in the case of irregular sampling.
Anomalous g-Factors for Charged Leptons in a Fractional Coarse-Grained Approach

description: In this work, we investigate aspects of the electron, muon and tau gyromagnetic ratios (g-factor) in a fractional coarse-grained scenario, by adopting a Modified Riemann-Liouville (MRL) fractional calculus. We point out the possibility of mapping the experimental values of the specie's g-factors into a theoretical parameter which accounts for fractionality, without computing higher-order QED calculations. We wish to understand whether the value of (g-2) may be traced back to a fractionality of space-time.The justification for the difference between the experimental and the theoretical value g=2 stemming from the Dirac equation is given in the terms of the complexity of the interactions of the charged leptons, considered as pseudo-particles and "dressed" by the interactions and the medium. Stepwise, we build up a fractional Dirac equation from the fractional Weyl equation that, on the other hand, was formulated exclusively in terms of the helicity operator. From the fractional angular momentum algebra, in a coarse-grained scenario, we work out the eigenvalues of the spin operator. Based on the standard electromagnetic current, as an analogy case, we write down a fractional Lagrangian density, with the electromagnetic field minimally coupled to the particular charged lepton. We then study a fractional gauge-like invariance symmetry, formulate the covariant fractional derivative and propose the spinor field transformation. Finally, by taking the non-relativistic regime of the fractional Dirac equation, the fractional Pauli equation is obtained and, from that, an explicit expression for the fractional g-factor comes out that is compared with the experimental CODATA value. Our claim is that the different lepton species must probe space-time by experiencing different fractionalities, once the latter may be associated to the effective interactions of the different families with the medium.

description: Besides welding, high temperature vacuum repair-brazing is already established for nickel-based alloy turbine blades in the aerospace and power plant industries. After the worn turbine blade has been decoated to its substrate material, the filler metal is deposited as a paste, (melt-spin) foil or tape which also consists of a nickel-based alloy. Following this, the hot-gas corrosion protective coating (e.g. NiCoCrAlY) is applied using thermal spraying. The brazed turbine blade is ground or milled to size and subsequently aluminized to further increase its corrosion resistance. Using the current state of technology, a turbine blade can undergo approximately 3 to 4 repair cycles. In the present study, the development of a two-stage hybrid technology for repairing turbine blades is considered which incorporates, on the one hand, a process technology and manufacturing aspects and, on the other hand, considers material-technological mechanisms. During the first stage of this hybrid technology, the filler metal together with the hot-gas corrosion protective coating is applied using thermal spraying. The subsequent second stage combines the brazing and aluminizing processes. The technology developed here brings technical and economic advantages whilst enabling the current state-of-the-art's corresponding process chain for repairing turbine blades to be shortened.
High-Resolution Observations and the Physics of High-Velocity Cloud A0

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The neutral hydrogen structure of high-velocity cloud A0 (at about -180 km/s) has been mapped with a 9.1 arcmin resolution. Gaussian decomposition of the profiles is used to separately map families of components defined by similarities in center velocities and line widths. About 70% of the HI gas is in the form of a narrow, twisted filament whose typical line widths are of order 24 km/s. Many bright features with narrow line widths of order 6 km/s, clouds, are located in and near the filament. A third category with properties between those of the filament and clouds appears in the data. The clouds are not always co-located with the broader line width filament emission as seen projected on the sky. Under the assumption that magnetic fields underlie the presence of the filament, a theorem is developed for its stability in terms of a toroidal magnetic field generated by the flow of gas along field lines. It is suggested that the axial magnetic field strength may be derived from the excess line width of the HI emission over and above that due to kinetic temperature by invoking the role of Alfven waves that create what is in essence a form of magnetic turbulence. At a distance of 200 pc the axial and the derived toroidal magnetic field strengths in the filament are then about 6 microGauss while for the clouds they are about 4 microGauss. The dependence of the derived field strength on distance is discussed.

This paper presents a design approach of a rotary table with an active magnetic bearing. Opportunities in machining through employing magnetic guides are presented and discussed in the beginning. In the following, a workflow for the magnetic bearing design in swivel rotary tables is proposed. The mentioned steps are executed based on a presently under design rotary table.

description: De nombreuses flambées dues au Serratia marcescens chez les nouveau-nés sont décrites dans la littérature. Toutefois, leur source est rarement identifiée. Aux hôpitaux universitaires de Genève, 2 nouveau-nés en néonatologie et 2 nouveau-nés dans une unité de développement ont été découverts colonisés par S. marcescens à partir du 7 mars 2013. Lors d’une première enquête de prévalence le 23 avril, 8 autres cas ont été identifiés. Population et méthodes. L’origine de l’épidémie a été recherchée en néonatologie par une enquête environnementale et par quatre enquêtes de prévalence de portage (prélèvements nasopharyngés et rectaux) entre avril et juin 2013. Des audits d’hygiène des mains (n = 439) ainsi que des audits de soins ont également été effectués dans ce service. Résultats. Au total 232 dépistages ont été réalisés auprès des nouveau-nés dont 20 étaient positifs à S. marcescens avec une souche génotypiquement identique. Suite à un programme de formation, l’observance de l’hygiène des mains s’est améliorée, passant de 51 % à 79 %. La source du germe n’a pas été identifiée car les 231 prélèvements environnementaux réalisés étaient tous négatifs. Deux autres enquêtes de prévalence menées de juin à octobre n’ont démontré aucun portage. Conclusion. L’épidémie a pu être contrôlée grâce à l’amélioration des pratiques concernant notamment l’hygiène des mains, à l’isolement des enfants, aux mesures spécifiques instaurées, à la collaboration interprofessionnelle, et à l’éducation des parents.

description: Contemporaines du développement de la médecine, redoutées tant par les populations que par ceux qui les soignent, les infections associées aux soins (IAS) ont fait l’objet d’intuitions remarquables pendant des millénaires. Toutefois, c’est surtout à partir du milieu du XVIIIe siècle qu’elles ont commencé à être appréhendées scientifiquement. Pendant les deux siècles qui ont suivi, les idées se sont mises en place, et les conditions de sécurité nécessaires à un réel développement des techniques de soins modernes ont été créées. Par la suite, les antibiotiques se sont imposés comme une révolution thérapeutique. Dans une grande partie des établissements de soins français, des méthodes de travail nouvelles (protocolisation, évaluation, audit, surveillance, benchmarking, vigilance, programme qualité) ont progressivement été mises en œuvre sous l’impulsion des hygiénistes hospitaliers, de leurs collègues et des patients eux-mêmes, avec une efficacité encore partielle mais déjà solidement établie. Plus important peut-être, le développement de l’hygiène a conforté une culture partagée de la sécurité qui commence désormais à imprégner le système de santé, et à développer des pratiques de coopération interdisciplinaire indispensables pour traiter de problématiques si complexes.

description: Modulation photoreflectance spectroscopy and Raman spectroscopy have been applied to study the electronic- and band-structure evolution in (Ga,Mn)As epitaxial layers with increasing Mn doping in the range of low Mn content, up to 1.2%. Structural and magnetic properties of the layers were characterized with high-resolution X-ray diffractometry and SQUID magnetometery, respectively. The revealed results of decrease in the band-gap transition energy with increasing Mn content in very low-doped (Ga,Mn)As layers with n-type conductivity are interpreted as a result of merging the Mn-related impurity band with the host GaAs valence band. On the other hand, an increase in the band-gap-transition energy with increasing Mn content in (Ga,Mn)As layers with higher Mn content and p-type conductivity indicates the Moss-Burstein shift of the absorption edge due to the Fermi level location within the valence band, determined by the free-hole concentration. The experimental results are consistent with the valence-band origin of mobile holes mediated ferromagnetic ordering in the (Ga,Mn)As diluted ferromagnetic semiconductor.

description: Le développement de l’antisepsie a constitué une contribution majeure à la maîtrise des risques infectieux. Il a bénéficié du travail de précurseurs universellement connus tels que Ignàc Fülop Semmelweis, Oliver Wendell Holmes ou Joseph Lister, tandis que d’autres sont devenus des noms « presque » communs comme Lugol, Labarraque, Dakin, Credé, etc. Ils ont participé de façon magistrale à cette belle histoire de la prévention des maladies infectieuses. On peut citer également l’Écossais John Pringle, qui a utilisé pour la première fois au milieu du XVIIIe siècle le mot « antiseptique », mais aussi Herman Shelanski, le génial concepteur de la polyvinylpyrrolidone-iodée, le Britannique William Griffiths et le Suisse Didier Pittet, les deux artisans de la mise au point et de l’utilisation généralisée des solutés hydroalcooliques pour le lavage des mains, qui ont économisé plusieurs millions de vies humaines ces deux dernières décennies. Cette histoire a également été le témoin de drames, comme celui du « talc Morhange » en France en 1972 au cours duquel une quarantaine de nouveau-nés décédèrent. Cet article présente les grandes étapes de cette histoire de l’antisepsie depuis les temps anciens jusqu’à aujourd’hui.

description: Clamping errors in workpiece positioning decrease the production outcome of machine tools by causing rejects. An automated monitoring of these failures does not take place in practice, due to limited installation space for the sensor integration, especially in series production. Within the Collaborative Research Centre 653, the IFW develops and investigates a condition and process monitoring system based on sensing clamping elements in close cooperation with two industrial partners, the companies Roemheld GmbH (clamping technology manufacturer) and ReiKam GmbH (fixture construction service provider). It consists of hydraulic clamping elements with integrated sensors, decentral electronics for signal preprocessing, bus communication and a central processing unit. Measureable quantities are hydraulic pressure, the clamping stroke and the process forces. This article describes the prototypical realization and shows its usability in condition and process monitoring. Experimental results from measurements during milling operations and the comparison with a dynamometer demonstrate the performance of the sensory clamping system.

Zero-mode dynamics in supersymmetric Yang-Mills-Chern-Simons theory

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider minimally supersymmetric Yang-Mills theory with a Chern-Simons term on a flat spatial two-torus in the limit when the torus becomes small. The zero-modes of the fields then decouple from the non-zero modes and give rise to a spectrum of states with energies that are given by multiples of the square of the coupling constant. We discuss the determination of this low-energy spectrum, both for simply connected gauge groups and for gauge groups of adjoint type, with a few examples worked out in detail.

NLO Analysis of Small-$k_T$ Region in Drell-Yan Production with Parton Branching

description: The Parton-Branching Method (PB) facilitates the determination of Transverse Momentum Dependent (TMD) parton densities across a wide \kt range, spanning small to large transverse momentum scales. In the small $k_T$ region, both intrinsic parton motion and resummed ultra-soft gluons are significant contributors. Our analysis highlights their crucial role in shaping integrated and TMD parton densities. Using PB-derived TMD parton densities and a NLO calculation in MC@NLO style, we compute the transverse momentum spectrum of Drell-Yan pairs across a broad mass range. The spectrum's sensitivity to the intrinsic $k_T$ distribution allows us to fine-tune parametric parameters. Starting from the PB-NLO-HERAI+II-2018 set2 TMD parton distributions, we determine the intrinsic $k_T$ distribution width, resulting in a slightly wider profile than the default set. Importantly, this width remains independent of Drell-Yan pair mass and center-of-mass energy ($\sqrt{s}$), distinguishing our approach.

description: Variable resistors were constructed from epitaxial SrRuO3 (SRO), La0.67Sr0.33MnO3 (LSMO) and SrTiO3 layers with perovskite crystal structure. Each layer was patterned separately by lithographic methods. Optimized wet chemical etchants and several polishing steps in organic solvents allowed good epitaxy of subsequent layers, comparable to epitaxy on pristine substrates. Periodate as the oxidizing agent for SRO and iodide with ascorbic acid as the reducing agents for LSMO were used to attack these chemically resistant oxides. The final devices changed their conductance in a similar manner to previously described variable resistors that were defined with shadow masks.

description: Currently, prediction of crack initiation by corrosion pits is only possible by assuming regular geometrical shapes, such as semi-spheres or semi-ellipsoids. Moreover, typical fatigue life diagrams associate the crack initiation life with geometrical features, such as pit depth or aspect ratio, often leading to unsatisfactory correlations due to high pit shape variability and data scatter. In the context of blade-disc fixation in aero engine turbines, this limitation translates into highly conservative life estimations. Therefore, a new crack initiation predictor is formulated based on experimental testing and numerical analysis of 28 artificial corrosion pits. A low-cycle fatigue test campaign is conducted using three-point bending test specimens to simulate maximum takeoff operation conditions of the aero engine and the associated loading of the blade root designed as firtree. An artificial pit is located at the critical point of each test specimen, respectively. The prediction criterion is based on finite element analysis and is formulated as the lowest plastic strain of a plastic region with a certain volume in the corrosion pit. This reference volume is varied until an optimum correlation with experimental crack initiation life is obtained. The criterion shows a superior correlation with crack initiation life compared to pure geometrical parameters such as pit depth.

description: A search for $K^-pp$ bound state (the lightest kaonic nucleus) has been performed using the $γd \rightarrow K^+ π^- \rm{X}$ reaction at E$_γ$=1.5-2.4 GeV at LEPS/SPring-8. The differential cross section of $K^+ π^-$ photo-production off deuterium has been measured for the first time in this energy region, and a bump structure was searched for in the inclusive missing mass spectrum. A statistically significant bump structure was not observed in the region from 2.22 to 2.36 GeV/$c^2$, and the upper limits of the differential cross section for the $K^-pp$ bound state production were determined to be 0.1$-$0.7 $μ$ b (95$%$ confidence level) for a set of assumed binding energy and width values.
