description: We present a unified approach for qualitative and quantitative analysis of stability and instability dynamics of positive bright solitons in multi-dimensional focusing nonlinear media with a potential (lattice), which can be periodic, periodic with defects, quasiperiodic, single waveguide, etc. We show that when the soliton is unstable, the type of instability dynamic that develops depends on which of two stability conditions is violated. Specifically, violation of the slope condition leads to an amplitude instability, whereas violation of the spectral condition leads to a drift instability. We also present a quantitative approach that allows to predict the stability and instability strength.

description: We characterize all random point measures which are in a certain sense stable under the action of branching. Denoting by $\circledast$ the branching convolution operation introduced by Bertoin and Mallein (2019), and by $\mathcal{Z}$ the law of a random point measure on the real line, we are interested in solutions to the fixed point equation \[ \mathcal E = \mathcal{Z} \circledast \mathcal E, \] with $\mathcal E$ a random point measure distribution. Under suitable assumptions, we characterize all solutions of this equation as shifted decorated Poisson point processes with a uniquely defined shift.

Swine waste odors : effects of gas stripping
Creators: name: Fattori, Michael
Publisher: name: University of British Columbia
Year: 2012

description: Liquid anaerobic waste collected from a swine finishing barn was chemically investigated. Various phenols, amines, sulfides and organic acids were identified in the waste and were shown to contribute to its odor. The rapid reduction in odor intensity brought about by short term aeration of the waste was studied with respect to these different compounds. The effectiveness of odor reduction by aeration was found to be contingent on the waste's pH. Reasons for this phenomenon are presented in terms of ionization constants for solutes, previously shown to be present in the waste.

description: We present a search for a Higgs boson decaying to two W bosons in ppbar collisions at sqrt(s)=1.96 TeV center-of-mass energy. The data sample corresponds to an integrated luminosity of 3.0 fb-1 collected with the CDF II detector. We find no evidence for production of a Higgs boson with mass between 110 and 200 GeV/c^2, and determine upper limits on the production cross section. For the mass of 160 GeV/c^2, where the analysis is most sensitive, the observed (expected) limit is 0.7 pb (0.9 pb) at 95% Bayesian credibility level which is 1.7 (2.2) times the standard model cross section.

The future smart grid features high penetration of renewables and more fast-moving power electronics inverters but raises challenges to the reliable frequency estimation. This article presents three methods to address these challenges.
The frequency estimated by the Phasor Measurement Unit (PMU) is a critical index of power system status and supports many smart grid applications. The future smart grid features high penetration of renewables and more fast-moving power electronics inverters but raises challenges to the reliable frequency estimation. This article presents three methods to address these challenges. First, an enhanced zero-crossing algorithm was developed to track the fast-changing frequency in system dynamics. Second, we propose a technology that can tolerate the system transient and suppress the outliers. Third, an algorithm was developed to export high time-resolution frequency estimations with minimum computational effort. All of the proposed methods are realized in hardware and compared with classical frequency estimation methods. The testing results indicate that the proposed methods have excellent performance. They can be used in future PMUs and provide reliable and high time resolution data for smart grid applications.

The insights and lessons from my lived-experiences within thepublic school system, first as a student and then as a parent of Indigenous students,propose a paradigm shift so that teacher candidates can understand Indigenous parentsand their lives better. Many Indigenous parents are influenced by severe life eventsthat inherently affect their participation or non-participation in public schools. It isimperative that Indigenous parents project their voices in the creation of responses andstrategies for parent-directed engagement and that teacher candidates are invited toconsider how they will understand parental engagement in their teaching practice. Todevelop positive strategies, parents, teachers, and administrators must be involved inthe educational planning process.

description: Die Zusammenstellung von Kurzerzählungen in Sammelhandschriften des 15. Jahrhunderts ist mehr als Kompilation. Durch Variation, durch Auswahl und Anordnung werden die Stoffe verglichen, verbunden oder kontrastiert. Titel und Schluss können markieren und kommentieren. In ihrer Gesamtheit determinieren diese Aspekte Rezeption und Interpretation der Geschichten im Einzelnen, sowie der Sammlung als Einheit. Trotzdem bleibt hier immer vieles offen, und die prüfende Lektüre weckt beim Lesenden ggf. zunehmende Unsicherheit anstatt Erkenntnis.
In der vorliegenden Arbeit wird eines der potentiell interpretativen Elemente herausgegriffen und auf seine Funktion geprüft: Die Schlussformeln der einzelnen Erzählungen einer Sammlung. Das sind stereotype Formulierungen, welche überwiegend auf das Ende der Texte verweisen, eine Gattungsbezeichnung sowie eine Bitte an Gott beinhalten.
Im Grunde ist es genau diese Bitte an Gott, die uns besonders interessiert, so stecken in den formelhaft anmutenden „Fürbitten“ oft sehr spezifische Wünsche. Was hier angeboten wird, sind subjektive, bisweilen „ungenaue“ oder aber auch irritierende bzw. provozierende Kurzdeutungen der Geschichten.
Die Analysekriterien der Gotteswünsche sind wie folgt gewählt: „positiv/negativ“, „formelhaft/spezifisch“. Liegt eine spezifische Formulierung vor, so wird diese auf ihre Kohärenz zur Moral der vorangehenden Erzählung geprüft. Unter Zuhilfenahme weiterer Bestandteile des Textes (z.B. Illustration und Überschrift) können sich dabei mitunter neue Perspektiven eröffnen.
Als Primärtext dient der Codex FB 32001 des Innsbrucker Museums Ferdinandeum (i) aus ~ 1456. Die Handschrift umfasst mit und ohne Autorangaben (u.a. Stricker, Konrad von Würzburg) 57 Kurzerzählungen im Versmaß, sowie zwei weitere, nachträglich hinzugefügte höfische Romanfragmente, die hier keine Bearbeitung finden.
Ziel der Analyse ist es, herauszuarbeiten, was die einzelnen Schlussformeln der Kurzerzählungen in Cod. 32001 verbindet oder unterscheidet, wie sie im Bezug zur jeweiligen Geschichte stehen und schließlich: welche Funktion sie als repetitives Element der Sammlung einnehmen.
Asynchronous Economic Dispatch for Combined Heat and Power Systems

Publisher: name: IEEE

In this article, the asynchronous dispatch method is proposed and instantiated by two different dispatch models featuring a short electric dispatch time scale and a long heat dispatch time scale.
In the day-ahead economic dispatch of combined heat and power systems, the electric power system is adjusted in minutes because of the short dynamic time and the requirement of real-time power balance, while the heating system is dispatched in hours due to its large inertia and long dynamic process. However, the different dispatch time scales of electricity and heat are ignored by existing synchronous dispatch methods, which limits the improvement of system efficiency. To address this challenge, in this article, the asynchronous dispatch method is proposed and instantiated by two different dispatch models featuring a short electric dispatch time scale and a long heat dispatch time scale. Case studies demonstrate the asynchronous dispatch method can overcome the efficiency and reliability problems caused by the existing synchronous dispatch methods.

description: Direct optimization of IR metrics has often been adopted as an approach to devise and develop ranking-based recommender systems. Most methods following this approach aim at optimizing the same metric being used for evaluation, under the assumption that this will lead to the best performance. A number of studies of this practice bring this assumption, however, into question. In this paper, we dig deeper into this issue in order to learn more about the effects of the choice of the metric to optimize on the performance of a ranking-based recommender system. We present an extensive experimental study conducted on different datasets in both pairwise and listwise learning-to-rank scenarios, to compare the relative merit of four popular IR metrics, namely RR, AP, nDCG and RBP, when used for optimization and assessment of recommender systems in various combinations. For the first three, we follow the practice of loss function formulation available in literature. For the fourth one, we propose novel loss functions inspired by RBP for both the pairwise and listwise scenario. Our results confirm that the best performance is indeed not necessarily achieved when optimizing the same metric being used for evaluation. In fact, we find that RBP-inspired losses perform at least as well as other metrics in a consistent way, and offer clear benefits in several cases. Interesting to see is that RBP-inspired losses, while improving the recommendation performance for all uses, may lead to an individual performance gain that is correlated with the activity level of a user in interacting with items. The more active the users, the more they benefit. Overall, our results challenge the assumption behind the current research practice of optimizing and evaluating the same metric, and point to RBP-based optimization instead as a promising alternative when learning to rank in the recommendation context.

description: We demonstrate the possibility of existence of meta-stable N-body Efimov states in trapped Bose systems with large scattering length. We calculate spectra of trapped systems of N=3,4,5,6, and 7 bosons using a stochastic variational method with a restricted correlated Gaussian basis. For each system the calculations reveal a series of Efimov states where the energy and the r.m.s. radius exhibit the characteristic exponential dependence upon the state number. We also estimate the contribution of these states to the recombination rate of Bose-Einstein condensates.

This webinar, "Fast Detection of Transformed Data Leaks," will discuss how the leak of sensitive data across secure network boundaries is becoming one of the most critical concerns for many industries in the move towards digitalization, building worldwide information portals, and the cloud. Due to the complex causes of data leaks, developers and researchers have created an umbrella of methods to identify, mitigate, and prevent leaks in different scenarios. This data leak detection webinar begins with a few distinct data leak cases and real-world countermeasures to inspire the audience to discover research problems. Then we pick up one set of detection problems regarding data comparison and dive into a string of detection approaches from simple to complex. Different design requirements regarding the deployment needs will be discussed, followed by existing solutions in the literature or commercial products. The last part of the webinar will generalize sensitive data into knowledge, connect data leak detection with other rapidly growing fields, and discuss potential research directions in the near future.

gegenübergestanden, zeigt die vorliegende Biografie, basierend auf zahlreichen
im Nachlass des Komponisten befindlichen Korrespondenzen, nicht nur einen
mit Behörden und Verlagen um Entschädigungen kämpfenden, sondern auch
einen konsequent um die Realisierung seiner zahlreichen Musikprojekte

description: The Walt Disney Company is one of the world's largest media groups, reaching millions of people across the globe every year. This aim of this thesis is to give an insight into how the Disney Movies Bambi 1, The Lion King 1 and Finding Nemo project the theme of violence. The first segment of this scientific work will illuminate a complex definition of the term “violence” in order to measure and analyse it using empirical methods. With thanks to a holistic methodological approach, using Philipp Mayring's content analysis along with a film analysis from Lothar Mikos, it will be shown that it is possible to answer the primary research questions. Basically, that each of the aforementioned movies contains a similar pattern of violence. This is mainly portrayed through acts of physical violence, which in most cases is connected to an intended target. It will also be shown that there are some creative aspects, such as music and color schemes, which are repeated constantly in all three movies.

This paper introduces a probabilistic approach to evaluate the reliability of wind power integrated power systems considering essential reliability services including frequency and voltage support, in conjunction with resource adequacy.
With the increasing penetration of renewable resources and the retirements of conventional coal-fired generation units, power systems are undergoing significant transformation with the instantaneous renewable generation penetration sometimes approaching over 50 percent of the demand. This transformation makes the need for comprehensive reliability assessment critical to properly account for the composite system adequacy and the sufficiency of essential reliability services (ERSs). This paper introduces a probabilistic approach to evaluate the reliability of wind power integrated power systems considering ERSs including frequency and voltage support, in conjunction with resource adequacy. To consider stochasticity in system operating conditions, the proposed approach utilizes sequential Monte-Carlo Simulation (SMCS) as the probabilistic analysis methodology and formulates probabilistic reliability metrics representing the composite system adequacy and the ERSs. The proposed approach and metrics are demonstrated on a synthetic test system. Simulation results illustrate the efficacy of the proposed approach and its importance in analyzing the impact of increasing wind power penetration as well as wind turbine generators (WTGs) providing ERSs on system reliability.

This article presents an overview of the challenges, implications, and potential strategies for wildfire risk mitigation in power systems, and introduces the vision for a wildfire-resilient power system.
Managing the risk of wildfires has been arguably the biggest recent challenge of electric utilities with infrastructure located in the wildland-urban interface. Utilities are deploying solutions for wildfire risk mitigation, such as public safety power shutoffs, which are counter-intuitive from a reliability-centric operation paradigm. This article presents an overview of the challenges, implications, and potential strategies for wildfire risk mitigation in power systems, and introduces the vision for a wildfire-resilient power system. The wildfire risk management strategies presented in this article range from fault prevention methods such as structural hardening, vegetation management and implementing advanced protection systems, to arc-suppression and ignition prevention methods. This article also identifies relevant research opportunities associated with implementing wildfire mitigation techniques on power systems.
What lead to the East Asian financial crisis?
Creators: name: Abdulgaleev, Niyaz

description: This master thesis uses a meta-analysis and systemic literature review approach aided with several digital citation services to analyse the various interpretations of the 1997 East Asian financial crisis conducted by the academic community. A ranking is created in order to find the most probable causes according to the views of economists and scholars. This thesis has found that a combination of hasty financial liberalisation with incompatible macroeconomic policies were responsible for building up vulnerabilities throughout the in in East-Asian economies. Although the vulnerabilities were present, the international market over-reacted through a self-fulfilling crisis and panic. A more specific analysis is repeated focusing only on the factors causing the crisis in South Korea and a ranking is created in the same manner. In the case of South Korea the causes have been similar to the general explanations in addition to focusing on the conglomerates known as chaebols and their growing inefficiencies and vulnerabilities.

description: Simple binary-state coordination models are widely used to study collective socio-economic phenomena such as the spread of innovations or the adoption of products on social networks. The common trait of these systems is the occurrence of large-scale coordination events taking place abruptly, in the form of a cascade process, as a consequence of small perturbations of an apparently stable state. The conditions for the occurrence of cascade instabilities have been largely analysed in the literature, however for the same coordination models no sufficient attention was given to the relation between structural properties of (Nash) equilibria and possible outcomes of dynamical equilibrium selection. Using methods from the statistical physics of disordered systems, the present work investigates both analytically and numerically, the statistical properties of such Nash equilibria on networks, focusing mostly on random graphs. We provide an accurate description of these properties, which is then exploited to shed light on the mechanisms behind the onset of coordination/miscoordination on large networks. This is done studying the most common processes of dynamical equilibrium selection, such as best response, bounded-rational dynamics and learning processes. In particular, we show that well beyond the instability region, full coordination is still globally stochastically stable, however equilibrium selection processes with low stochasticity (e.g. best response) or strong memory effects (e.g. reinforcement learning) can be prevented from achieving full coordination by being trapped into a large (exponentially in number of agents) set of locally stable Nash equilibria at low/medium coordination (inefficient equilibria). These results should be useful to allow a better understanding of general coordination problems on complex networks.

description: Institutional barriers resulting from structural components in low and middle-income countries (LMICs) may impede the governance of a public health insurance (PHI) system during its primary phases. This study reports a mixed-method case study on cost containment challenges related to institutional barriers in the expansion of PHI in China. The quantitative analysis reveals that migrant patients with PHI who sought obstetric care in different areas during the examined period were institutionally considered out-of-pocket (cash) payers and paid an additional 28% in expenses. The qualitative findings corroborate the quantitative results, suggesting that there is widespread institutional discrimination against migrant patients, which extends beyond just one hospital. The ineffectiveness of policies designed to regulate physician behaviour in other regions can be attributed to the absence of interregional collaborative governance, which is hindered by institutional structural constraints. China has provided useful insights to LMICs regarding how to circumvent the institutional barriers that may inevitably arise during the development of PHI.

Teacher education programs have begun to include required Indigenous education courses for all teacher candidates and new courses or approaches about Indigenous education based on Indigenous knowledge systems. We need to know more about how these courses are being received and what impact they have on teacher candidates.

description: Da es in den letzten Jahren zahlreiche Forderungen von Experten und Institutionen nach mehr finanzieller Allgemeinbildung gab, wurde in der vorliegenden Arbeit erörtert, inwiefern finanzmathematisches Grundwissen zu finanzieller Allgemeinbildung beiträgt. Darauf aufbauend wurden die Fragestellungen, ob auf finanzmathematische Themen in der Sekundarstufe 2 an allgemeinbildenden höheren Schulen intensiver eingegangen werden soll und ob die Einführung der standardisierten kompetenzorientierten Reifeprüfung diesbezüglich bereits Auswirkungen gezeigt hat, entwickelt. Eine genaue Betrachtung der aktuellen Lehrpläne, Kompetenzlisten für die standardisierten Reifeprüfungen und approbierten Schulbücher bestätigte, dass Schülerinnen und Schüler einer allgemeinbildenden höheren Schule im Vergleich zu bestimmten anderen Schulformen deutlich weniger finanzmathematische Aspekte im Unterricht bearbeiten. Zusätzlich brachte die Befragung von Mathematik-Lehrkräften an allgemeinbildenden höheren Schulen das Ergebnis, dass Finanzmathematik in der Schulbildung wichtig sei und eine intensivere Behandlung solcher Thematiken im Grunde wünschenswert wäre. Die Umfrageresultate zeigten sowohl positive als auch negative Auswirkungen auf das Unterrichtsverhalten der Lehrpersonen bezüglich Finanzmathematik durch die Einführung der standardisierten Reifeprüfung.

description: In this paper, we investigate the parameter identification problem in dynamical systems through a deep learning approach. Focusing mainly on second-order, linear time-invariant dynamical systems, the topic of damping factor identification is studied. By utilizing a six-layer deep neural network with different recurrent cells, namely GRUs, LSTMs or BiLSTMs; and by feeding input-output sequence pairs captured from a dynamical system simulator, we search for an effective deep recurrent architecture in order to resolve damping factor identification problem. Our study results show that, although previously not utilized for this task in the literature, bidirectional gated recurrent cells (BiLSTMs) provide better parameter identification results when compared to unidirectional gated recurrent memory cells such as GRUs and LSTM. Thus, indicating that an input-output sequence pair of finite length, collected from a dynamical system and when observed anachronistically, may carry information in both time directions for prediction of a dynamical systems parameter.

description: A method to produce a spin-dependent rotating potential using near-resonant circularly polarized laser beams is proposed. It is shown that half-quantum vortices are nucleated in a spinor Bose-Einstein condensate with an antiferromagnetic interaction. In contrast to the vortex nucleation in a scalar BEC, the spin-vortex nucleation occurs at a low rotation frequency ($\simeq 0.1 ω_\perp$ with $ω_\perp$ being the radial trap frequency) in a short nucleation time $\simeq 50$ ms without dissipation. A method for nondestructive measurement of half-quantum vortices is discussed.

This paper investigates the impact of different frequency control constraints on the unit commitment of power plants resulting from market simulations.
The whole interconnected European network is involved in the energy transition towards power systems based on renewable power electronics interfaced generation. In this context, the major concerns for both network planning and operation are the inertia reduction and the frequency control due to the progressive decommissioning of thermal power plants with synchronous generators. This paper investigates the impact of different frequency control constraints on the unit commitment of power plants resulting from market simulations. The market outputs are compared in terms of system costs, and of frequency stability performance evaluated on the basis of the rate of change of frequency and the maximum frequency excursion. The best compromise solution is found using a multiple-criteria decision analysis method, depending on the choice of the decision maker's weighting factors. The proposed approach is tested on a real case taken from one of the most relevant future scenarios of the Italian transmission system operator. The results show how the best compromise solution that can be found depends on the decision maker preference towards cost-based or frequency stability-based criteria.

This paper proposes model-based system-level design and maintenance strategies in Power Electronic-based Power Systems based on the reliability model of converters.
Power electronic converters will serve as the fundamental components of modern power systems. However, they may suffer from poorer reliability if not properly designed, consequently affecting the overall performance of power systems. Accordingly, the converter reliability should be taken into account in design and planning of Power Electronic-based Power Systems (PEPSs). Optimal decision-making in planning of PEPSs requires precise reliability modeling in converters from component up to system-level. This paper proposes model-based system-level design and maintenance strategies in PEPSs based on the reliability model of converters. This will yield a reliable and economic planning of PEPSs by proper sizing of converters, cost-effective design of converter components, identifying and strengthening the converter weakest links, as well as optimal maintenance scheduling of converters. Numerical case studies demonstrate the effectiveness of the proposed design and planning strategies for modern power systems.

description: The dependencies of the melting point and the lattice parameter of supported metal nanoclusters as functions of clusters height are theoretically investigated in the framework of the uniform approach. The vacancy mechanism describing the melting point and the lattice parameter shifts in nanoclusters with decrease of their size is proposed. It is shown that under the high vacuum conditions (p<10^-7 torr) the essential role in clusters melting point and lattice parameter shifts is played by the van der Waals forces of cluster-substrate interation. The proposed model satisfactorily accounts for the experimental data.

description: The Exascale Computing Project (ECP) is invested in co-design to assure that key applications are ready for exascale computing. Within ECP, the Co-design Center for Particle Applications (CoPA) is addressing challenges faced by particle-based applications across four sub-motifs: short-range particle-particle interactions (e.g., those which often dominate molecular dynamics (MD) and smoothed particle hydrodynamics (SPH) methods), long-range particle-particle interactions (e.g., electrostatic MD and gravitational N-body), particle-in-cell (PIC) methods, and linear-scaling electronic structure and quantum molecular dynamics (QMD) algorithms. Our crosscutting co-designed technologies fall into two categories: proxy applications (or apps) and libraries. Proxy apps are vehicles used to evaluate the viability of incorporating various types of algorithms, data structures, and architecture-specific optimizations and the associated trade-offs; examples include ExaMiniMD, CabanaMD, CabanaPIC, and ExaSP2. Libraries are modular instantiations that multiple applications can utilize or be built upon; CoPA has developed the Cabana particle library, PROGRESS/BML libraries for QMD, and the SWFFT and fftMPI parallel FFT libraries. Success is measured by identifiable lessons learned that are translated either directly into parent production application codes or into libraries, with demonstrated performance and/or productivity improvement. The libraries and their use in CoPA's ECP application partner codes are also addressed.

description: High-entropy metallic glasses (HEMGs), characterized by both compositional and structural disorders, serve as exemplary systems for exploring entropy effects. This study shows that a Fe25Co25Mn25Si10B15 HEMG significantly outperforms conventional Fe-based MGs and reduced iron in degrading azo dyes in a neutral environment. Through experiments and density functional theory calculations, it is identified that three entropy-related factors boost the reactivity: the high-entropy structure leading to an uneven charge distribution, the well-dispersed Fe atoms initiating the reaction, and the disordered structure activating otherwise inactive Co atoms. These factors collectively enhance the reactivity, highlighting how entropy can influence chemical properties of alloys. Through experiments and DFT calculations on a Fe25Co25Mn25Si10B15 high-entropy metallic glass, it is demonstrated that entropy can profoundly impact alloys’ chemical processes by modulating the electronic states and elemental reactivity.

description: Zu den „bevorteilt“ bearbeiteten Kapiteln der Weltkriegspsychiatrie zählt jedenfalls die Behandlung jener kriegstraumatisierten Soldaten, die unter dem Begriff „Kriegszitterer“ in die Geschichte eingingen und die Psychiatrie von 1914-1918 zu definieren scheinen. Eine Fokussierung auf die Behandlung der Kriegszitterer bedeutet aber oft auch eine Schwerpunktsetzung auf Feldlazarette, Garnisonsspitäler und andere militärische Krankenanstalten. Doch auch die Auseinandersetzung mit zivilen Spitälern fand oft im Hinblick auf dieses Phänomen statt. Es ist vor diesem Hintergrund daher zunächst nicht überraschend, dass die „Kaiser-Franz-Josef-Heil- und Pflegeanstalt Mauer-Öhling“ und ihre Entwicklung während der Zeit des Ersten Weltkrieges noch nicht bearbeitet wurden, denn Kriegszitterer sucht man in den Patientinnen- und Patientenlisten in der Tat vergebens. Im Vordergrund dieser Arbeit stehen die Pfleglinge. Um Erkenntnisse über den Einfluss des Ersten Weltkrieges auf diese zu gewinnen, wurde mithilfe von quantitativen geschichtswissenschaftlichen Methoden Erkenntnisse über Fragen nach der „Patientenbewegung“, den Diagnoseverteilungen, der Verweildauer und für den Ersten Weltkrieg typischer Phänomene gewonnen. Hierbei wurde im Allgemeinen und in Bezug auf bestehende Erkenntnisse der Psychiatrie- und Regionalgeschichte des Ersten Weltkrieges im Bezirk Amstetten diese um die in der Bearbeitung der Standesprotokolle gewonnenen Erkenntnisse ergänzt werden, und im Speziellen sich mit den genuin auf Mauer-Öhling bezogenen und der spitalseigenen Geschichte auseinandergesetzt und diese fortgesetzt werden.
Darüber hinaus lässt sich aufgrund des Archivmaterials die Frage stellen (und auch beantworten), welchen Einfluss der Erste Weltkrieg auf eine zivile österreichische Psychiatrie hatte. Wie machte er sich in der Patientinnen- und Patientenpopulation bemerkbar? Wie beeinflusste er die Diagnoseverteilung? Welche Rolle spielten „Kriegszitterer“ in einem zivilen Spital und welche Funktion hatte Mauer-Öhling in der Betreuung „kriegsbeschädigter“ Soldaten?
