description: Clays and micas are receiving attention as materials that, in their atomically thin form, could allow for novel proton conductive, ion selective, osmotic power generation, or solvent filtration membranes. The interest arises from the possibility of controlling their properties by exchanging ions in the crystal lattice. However, the ion exchange process itself remains largely unexplored in atomically thin materials. Here we use atomic-resolution scanning transmission electron microscopy to study the dynamics of the process and reveal the binding sites of individual ions in atomically thin and artificially restacked clays and micas. Imaging ion exchange after different exposure time and for different crystal thicknesses, we find that the ion diffusion constant, D, for the interlayer space of atomically thin samples is up to 10^4 times larger than in bulk crystals and approaches its value in free water. Surprisingly, samples where no bulk exchange is expected display fast exchange if the mica layers are twisted and restacked; but in this case, the exchanged ions arrange in islands controlled by the moiré superlattice dimensions. We attribute the fast ion diffusion to enhanced interlayer expandability resulting from weaker interlayer binding forces in both atomically thin and restacked materials. Finally, we demonstrate images of individual surface cations for these materials, which had remained elusive in previous studies. This work provides atomic scale insights into ion diffusion in highly confined spaces and suggests strategies to design novel exfoliated clays membranes.

description: Convolutional beamformers integrate the multichannel linear prediction model into beamformers, which provide good performance and optimality for joint dereverberation and noise reduction tasks. While longer filters are required to model long reverberation times, the computational burden of current online solutions grows fast with the filter length and number of microphones. In this work, we propose a low complexity convolutional beamformer using a Kalman filter derived affine projection algorithm to solve the adaptive filtering problem. The proposed solution is several orders of magnitude less complex than comparable existing solutions while slightly outperforming them on the REVERB challenge dataset.

description: Mapping a truncated optimization method into a deep neural network, deep unfolding network (DUN) has attracted growing attention in compressive sensing (CS) due to its good interpretability and high performance. Each stage in DUNs corresponds to one iteration in optimization. By understanding DUNs from the perspective of the human brain's memory processing, we find there exists two issues in existing DUNs. One is the information between every two adjacent stages, which can be regarded as short-term memory, is usually lost seriously. The other is no explicit mechanism to ensure that the previous stages affect the current stage, which means memory is easily forgotten. To solve these issues, in this paper, a novel DUN with persistent memory for CS is proposed, dubbed Memory-Augmented Deep Unfolding Network (MADUN). We design a memory-augmented proximal mapping module (MAPMM) by combining two types of memory augmentation mechanisms, namely High-throughput Short-term Memory (HSM) and Cross-stage Long-term Memory (CLM). HSM is exploited to allow DUNs to transmit multi-channel short-term memory, which greatly reduces information loss between adjacent stages. CLM is utilized to develop the dependency of deep information across cascading stages, which greatly enhances network representation capability. Extensive CS experiments on natural and MR images show that with the strong ability to maintain and balance information our MADUN outperforms existing state-of-the-art methods by a large margin.

description: In this work, we experimentally and numerically investigate the propagation and attenuation of vertically polarized surface waves in an unconsolidated granular medium equipped with small-scale metabarriers of different depths, i.e., arrays composed of one, two, and three embedded layers of sub-wavelength resonators. Our findings reveal how such a multi-layer arrangement strongly affects the attenuation of the surface wave motion within and after the barrier. When the surface waves collide with the barriers, the wavefront is back-scattered and steered downward underneath the oscillators. Due to the stiffness gradient of the granular medium, part of the wavefield is then rerouted to the surface level after overcoming the resonant array. Overall, the in-depth insertion of additional layers of resonators leads to a greater and broader band wave attenuation when compared to the single layer case.

description: Fast and reliable trajectory planning is a key requirement of autonomous vehicles. In this paper we introduce a novel technique for planning the route of an autonomous vehicle on a straight rural road using the Spin model checker. We show how we can combine Spins ability to identify paths violating temporal properties with sensor information from a 3D Unity simulation of an autonomous vehicle, to plan and perform consecutive overtaking manoeuvres on a traffic heavy road. This involves discretising the sensory information and combining multiple sequential Spin models with a Linear Time Temporal Logic specification to generate an error path. This path provides the autonomous vehicle with an action plan. The entire process takes place in close to realtime using no precomputed data and the action plan is specifically tailored for individual scenarios. Our experiments demonstrate that the simulated autonomous vehicle implementing our approach can drive on average at least 40km and overtake 214 vehicles before experiencing a collision, which is usually caused by inaccuracies in the sensory system. While the proposed system has some drawbacks, we believe that our novel approach demonstrates a potentially powerful future tool for efficient trajectory planning for autonomous vehicles.

description: The applicability of bosonization and the Anderson-Yuval (AY) approach at strong coupling is investigated by considering two generic impurity models: the multichannel interacting resonant-level and the anisotropic Kondo models. The two methods differ in the renormalization of the conduction-electron density of states (DoS) near the impurity site. Reduction of the DoS, absent in bosonization but accounted for in the AY approach, is shown to be vital in some models yet redundant in others. The criterion being the stability of the strong-coupling fixed point. Renormalization of the DoS is essential for an unstable fixed point, but redundant when a decoupled entity with local dynamics is formed. This rule can be used to boost the accuracy of both methods at strong coupling.

description: We propose and describe a magnetic NanoFabric which provides a route to building reconfigurable spin-based logic circuits compatible with conventional electron-based devices. A distinctive feature of the proposed NanoFabric is that a bit of information is encoded into the phase of the spin wave signal. It makes possible to transmit information without the use of electric current and utilize wave interference for useful logic functionality. The basic elements include voltage-to-spin wave and wave-to-voltage converters, spin waveguides, a modulator, and a magnetoelectric cell. As an example of a magnetoelectric cell, we consider a two-phase piezoelectric-piezomagnetic system, where the spin wave signal modulation is due to the stress-induced anisotropy caused by the applied electric field. The performance of the basic elements is illustrated by experimental data and results of numerical modeling. The combination of the basic elements let us construct magnetic circuits for NOT and Majority logic gates. Logic gates AND, OR, NAND and NOR are shown to be constructed as the combination of NOT and a reconfigurable Majority gates. The examples of computational architectures such as Cellular Automata, Cellular Nonlinear Network and Field Programmable Gate Array are described. The main advantage of the proposed NanoFabric is in the ability to realize logic gates with less number of devices than it required for CMOS-based circuits. Potentially, the area of the elementary reconfigurable Majority gate can be scaled down to 0.1um2. The disadvantages and limitations of the proposed NanoFabric are discussed.

description: In this paper we consider three classes of interacting particle systems on $\mathbb Z$: independent random walks, the exclusion process, and the inclusion process. We allow particles to switch their jump rate (the rate identifies the type of particle) between $1$ (fast particles) and $ε\in[0,1]$ (slow particles). The switch between the two jump rates happens at rate $γ\in(0,\infty)$. In the exclusion process, the interaction is such that each site can be occupied by at most one particle of each type. In the inclusion process, the interaction takes places between particles of the same type at different sites and between particles of different type at the same site. We derive the macroscopic limit equations for the three systems, obtained after scaling space by $N^{-1}$, time by $N^2$, the switching rate by $N^{-2}$, and letting $N\to\infty$. The limit equations for the macroscopic densities associated to the fast and slow particles is the well-studied double diffusivity model. This system of reaction-diffusion equations was introduced to model polycrystal diffusion and dislocation pipe diffusion, with the goal to overcome the limitations imposed by Fick's law. In order to investigate the microscopic out-of-equilibrium properties, we analyse the system on $[N]=\{1,\ldots,N\}$, adding boundary reservoirs at sites $1$ and $N$ of fast and slow particles, respectively. Inside $[N]$ particles move as before, but now particles are injected and absorbed at sites $1$ and $N$ with prescribed rates that depend on the particle type. We compute the steady-state density profile and the steady-state current. It turns out that uphill diffusion is possible, i.e., the total flow can be in the direction of increasing total density. This phenomenon, which cannot occur in a single-type particle system, is a violation of Fick's law made possible by the switching between types.

description: We analyze analytically the asymptotic regions of the quasinormal mode frequency spectra with infinitely large overtone numbers for $D$-dimensional Schwarzschild black holes in anti de Sitter spacetimes. In this limit, we confirm the analytic results obtained previously in the literature using different methods. In addition, we show that in certain spacetime dimensions these techniques imply the existence of other regions of the asymptotic quasinormal mode frequency spectrum which have not previously appeared in the literature. For large black holes, some of these modes have a damping rate of $1.2T_H$, where $T_H$ is the Hawking temperature. This is less than the damping rate of the lowest overtone quasinormal mode calculated by other authors. It is not completely clear whether these modes actually exist or are an artifact of an unknown flaw in the analytic techniques being used. We discuss the possibility of the existence of these modes and explore some of the consequences. We also examine the possible connection between the asymptotic quasinormal modes of Schwarzschild-anti de Sitter black holes and the quantum level spacing of their horizon area spectrum.

description: Although railway dispatching on large national networks is gradually becoming more computerized, there are still major obstacles to retrofitting (semi-)autonomous control systems. In addition to requiring extensive and detailed digitalization of infrastructure models and information systems, exact optimization for railway dispatching is computationally hard. Heuristic algorithms and manual overrides are likely to be required for semi-autonomous railway operations for the foreseeable future. In this context, being able to detect problems such as deadlocks can be a valuable part of a runtime verification system. If bound-for-deadlock situations are correctly recognized as early as possible, human operators will have more time to better plan for recovery operations. Deadlock detection may also be useful for verification in a feedback loop with a heuristic or semi-autonomous dispatching algorithm if the dispatching algorithm cannot itself guarantee a deadlock-free plan. We describe a SAT-based planning algorithm for online detection of bound-for-deadlock situations. The algorithm exploits parallel updates of train positions and a partial order reduction technique to significantly reduce the number of state transitions (and correspondingly, the sizes of the formulas) in the SAT instances needed to prove whether a deadlock situation is bound to happen in the future. Implementation source code and benchmark instances are supplied, and a direct comparison against another recent study demonstrates significant performance gains.

title: Operando characterisation of oxide-supported bimetallic Pd-Pt nanocatalysts for methane oxidation
Creators: name: Large, Alexander Ian
Publisher: name: University of Reading
Year: 2021

description: Near-ambient pressure x-ray photoelectron spectroscopy (NAP-XPS) was utilised to understand the relationship between the surface chemistry and reactivity of catalysts for the complete oxidation of methane. This reaction is of interest for removing unburnt methane in vehicle exhausts, due to the high global warming potential of methane. A wide range of palladium, platinum, and palladium-platinum catalysts - both real powder catalysts and model systems - were studied for complete methane oxidation. Powder catalyst studies showed that palladium was significantly better than platinum in all relevant tested conditions. Exchanging palladium for platinum showed some benefits, most importantly decreasing the deactivation suffered in wet conditions - a key negative of palladium catalysts. NAP-XPS was utilised to investigate whether understanding the surface states could aid the development of catalysts. This showed some correlations between activity and palladium oxidation state for alumina-supported samples, with benefits seen to retaining significant amounts of Pd(0) on the surface. Pd-Pt catalysts consistently had a higher presence of reduced palladium, compared to Pd catalysts. An increased platinum presence ensures more Pd(0) is present on the catalyst, partially explaining the increased activity of bimetallic catalysts under select conditions. Support effect studies compared silica, alumina and silica-alumina supported catalysts of equivalent loading. A mixed silica-alumina support (90Al2O3-10SiO2) typically performed best, though the margins between this, silica and alumina were often very small for a given condition. NAP-XPS showed a less direct correlation between oxidation of palladium and catalytic activity, with other effects of support variation (grain size, particle size) having greater impacts. Issues with charging and signal in NAP-XPS experiments prompted the development of thin film model catalysts, utilising thin layers of alumina with nanoparticles of palladium deposited onto the surface using a cluster source. This method allowed for the production of samples with similar surface loadings, which were superior in regards to sample charging for XPS. Additionally, they were shown to behave in similar ways under methane oxidation conditions by NAP-XPS, with dynamic reduction and oxidation of palladium. Temperature-programmed NAP-XPS work on palladium foils under reaction conditions showed that a lower oxygen concentration or higher water concentration in the gas feed caused the oxidation of palladium to be inhibited. Pd-Pt foils were studied, with even greater inhibition of Pd oxidation seen with higher Pt loading. Where palladium was oxidised, platinum was typically migrating into the bulk of the foil. Platinum migrating to the bulk of Pd-Pt systems was also seen in thin film studies. Combined with the powder results, this is a clear sign that platinum presence aids palladium retaining a reduced state.

description: Forests are asked to provide a multitude of ecosystem services and forest managers need to ensure in their daily work these are well balanced. This is a demanding task and requires best available knowledge and continuous training. To serve such needs the software package ‘I+’ was developed jointly by research and software developers and tested by practitioners. It runs on handheld devices and is used for training exercises in designated forest sites, so called marteloscopes. I+ allows to perform virtual tree selections and directly displays the outcomes of silvicultural interventions on site. Having intervention results readily available stimulatesfactbased interaction and discussion among exercise participants. The software is currently tailored to address impacts and trade-offs of biodiversity conservation in commercially managed forests.Due to its modular design, it can easily be expanded to cover other highly relevant forest management topics such as carbon balancing. Through data export functions, exercise results can be utilized in more sophisticated tools such as forest growth simulators. The paper presents the key parameters used for training and the corresponding software solution. The I+ software components are then illustrated along examples. The software is freely available for download at the ‘Iplus’ website.

Flavonoid systematics of North American Lupinus species (Leguminosae)
Creators: name: Nicholls, Kevin William
Publisher: name: University of British Columbia
Year: 2010

description: This study was an assessment of the usefulness of flavonoids as taxonomic markers in the genus Lupinus (Leguminosae). The genus itself is readily recognizable, but, in North America, specific boundaries are poorly defined. This is probably the result of a combination of considerable morphological plasticity and hybridization (particularly amongst the outcrossing perennial taxa). At the outset, a detailed analysis of Lupinus flavonoids was made. Fifty-six compounds were identified, the majority being flavones based on apigenin, luteolin and less commonly acacetin and chrysoeriol. Glucose was the only sugar attached to flavonoids but was found C-bonded at the 6- or 8- positions and 0-bonded at the 5,7,3' or 4'-positions. Some flavonols and isoflavones were also identified. The reliability of flavonoids as specific characters was next tested. Fresh or dried plant material had identical flavonoid content, and plants of varying ages were chemically identical. Geographically, quantitative variation in flavonoid content was noted in an analysis of Lupinus sericeus by high pressure liquid chromatography. A sharp discontinuity in orientin levels was seen between populations north and south of Great Salt Lake, Utah, lending support to the subspecific ranking of the southerly population by Fleak (1971). Subsequent analysis of plants grown in uniform conditions showed the flavonoid differences to have been a phenotypic response. Since flavonoids appeared to be infraspecifically stable characters, an interspecific study of 73 taxa was made. Principal components analysis exposed 7 chemical groups. Six of these accumulated some novel flavonoids peculiar to each group. The seventh group had profiles containing no unusual compounds. One species (L. diffusus) had a very complex profile and was classed as a monospecific group. Using.the literature and personal observations it was seen that in 5 groups the chemical affinities paralleled morphological affinities thereby strengthening the integrity of the groups as natural units. Group C, however, was divided into two on the basis of morphological discontinuities as was the seventh group (F).which contained a collection of lupines with doubtful affinities (chemical or morphological). Overall, it is concluded that flavonoids are good specific characters in Lupinus. Their distribution, interspecifically, lends support to the recognition of some previously described subgeneric groupings that were based on morphology. In other cases, flavonoid data suggests affinities between some taxa that hitherto were considered unrelated.

description: In this paper new exact solutions in eight dimensional Lovelock theory will be presented. These solutions are vacuum static wormhole, black hole and generalized Bertotti-Robinson space-times with nontrivial torsion. All the solutions have a cross product structure of the type $M_{5}\times Σ_{3} $ where $M_{5}$ is a five dimensional manifold and $Σ_{3}$ a compact constant curvature manifold. The wormhole is the first example of a smooth vacuum static Lovelock wormhole which is neither Chern-Simons nor Born-Infeld. It will be also discussed how the presence of torsion affects the "navigableness" of the wormhole for scalar and spinning particles. It will be shown that the wormhole with torsion may act as "geometrical filter": a very large torsion may "increase the traversability" for scalars while acting as a "polarizator" on spinning particles. This may have interesting phenomenological consequences.

The research emphasizes the advantages of incorporating technology 4.0 to streamline the hiring process, but it also draws attention to the potential for prejudice brought about by the misuse of AI. It was also emphasized how crucial it is to approach the hiring process with consideration for gender. The investigation's findings are displayed according to the respondents' unique attributes, such as their age, gender, occupation, years of experience, and the length of the interviews, stated in minutes. to gain a sense of how gender discrimination in the workplace is affected by digitizing recruitment.
Die Wahrheit liegt auf dem Platz
Creators: name: Modrey, Eva
Publisher: name: KULT_online
Year: 2008

description: "Die Wahrheit liegt auf dem Platz." Diese bekannte Aussage von Otto Rehagel verrät bei näherem Hinsehen mehr, als beim ersten Hören assoziiert werden kann. Denn nur auf den "Platz" beschränkt sich das Spiel mit dem Fußball nicht. Vielmehr laufen hier die unterschiedlichen Stränge von Wirtschaft, Politik und Gesellschaft zusammen, und "auf dem Platz" spiegeln sich gesellschaftliche Prozesse. So lautet die Erkenntnis der vor allem in den letzten Jahren florierenden kulturwissenschaftlichen Fußball-Forschung, die die verschiedenen Beiträge des 592 Seiten schweren Sammelbandes, herausgegeben von dem Bochumer Historiker Jürgen Mittag und seinem Bochumer Kollegen, dem Politologen Jörg Uwe Nieland, prägnant zusammenfassen. Es gelingt ihnen nicht nur die Wechselwirkung der unterschiedlichen Teilbereiche von Politik über Kultur, bis hin zu Ökonomie und Medien mit dem so beliebten Volkssport Fußball darzustellen, sondern dies auch theoretisch unterfüttern.

Wie Religion Frieden stiftet
Creators: name: Laszlo, Stefan
Publisher: name: KULT_online
Year: 2008

description: Der von Manfred Brocker und Mathias Hildebrandt herausgegebene Band stellt die Frage nach dem friedensstiftenden Potential von Religion. Dieses wurde angesichts der von Samuel Huntington entfachten Diskussion vom religionsimprägnierten "Kampf der Kulturen" und insbesondere nach dem 11. September 2001 kaum noch wahrgenommen. Mit der vorliegenden Publikation, hervorgegangen aus der bereits 2004 zum Thema durchgeführten Jahrestagung des Arbeitskreises ‚Politik und Religion’ der Deutschen Vereinigung für Politische Wissenschaft, setzten die Herausgeber bei diesem Manko an. Die interdisziplinär angelegten Beiträge des Bandes analysieren das Befriedungspotential religiöser Akteure aus theologischer, historischer, philosophischer und politikwissenschaftlicher Perspektive und lösen das Ziel des Bandes, durch eine erste Bestandsaufnahme zum Thema zu weiteren Studien anzuregen, konstruktiv ein. Im Kern besteht die Beantwortung der titelgebenden Ausgangsfrage aus einem "Ja, wenn", wobei diese vermeintlich simple Schlussfolgerung in ihrer Komplexität entfaltet wird und neben erforderlichen Bedingungen gute Gründe und Möglichkeiten aufgezeigt werden, warum es notwendig und gewinnbringend ist, Religion mit wohlwollender Offenheit zu begegnen.

Геометрия и физика двумерных алгебр как язык причинности и свития
Creators: name: Басаргин, Олег Сергеевич
Publisher: name: Zenodo
Year: 2025

description: Двумерные алгебры, рассмотренные С.С. Кокаревым и Д. Павловым, раскрываются как особый класс структур, в которых причинность и порядок следования событий определяются не внешними параметрами, а внутренними законами самой алгебры. В данной статье предложено прочтение этих алгебр через концепцию Сфирали — геометрического устройства, в котором витки, петли и узлы реализуют алгебраические операции, ритм времени и смену полюсов. Такая интерпретация позволяет говорить о свитии как о фундаментальном механизме упорядочивания, противоположном линейному "развитию".

description: V současnosti se problematikou kvality zelených prostranství zabývá široké spektrum architektonické obce, které reaguje na podněty samospráv měst a obcí, ale i soukromých investorů. V důsledku masivní suburbanizace se společenský život lidí pře- souvá za hranice měst a soukromé prostory začínají být popu- lárnější než veřejná prostranství, na jejichž hodnotu se však za- tím stále nezapomíná. S důrazem na zlepšení aktuálního stavu a vzhledem k aktuálnosti tématu, jakož i chybějících regulací, nekoncepčních přístupů a nejednotnosti, je nutné spoléhat se primárně na odborná řešení. Ta mají za úkol řešit jak krátkodobé, tak především dlouhodobé cíle v horizontu několika let. Projekt, který samosprávě představili Ing. Markéta Zajíčková a Ing. Michal Pôbiš, tyto nároky splňuje, zatímco současná aktivita skupiny místních obyvatel představuje spíše zmiňované řešení bez jasné koncepce.
Observable and Attention-Directing BDI Agents for Human-Autonomy Teaming

description: Human-autonomy teaming (HAT) scenarios feature humans and autonomous agents collaborating to meet a shared goal. For effective collaboration, the agents must be transparent and able to share important information about their operation with human teammates. We address the challenge of transparency for Belief-Desire-Intention agents defined in the Conceptual Agent Notation (CAN) language. We extend the semantics to model agents that are observable (i.e. the internal state of tasks is available), and attention-directing (i.e. specific states can be flagged to users), and provide an executable semantics via an encoding in Milner's bigraphs. Using an example of unmanned aerial vehicles, the BigraphER tool, and PRISM, we show and verify how the extensions work in practice.

Dialoge zwischen Text und Fotografie
Creators: name: Hillenbach, Anne
Publisher: name: KULT_online
Year: 2008

description: Thomas von Steinaecker untersucht in seiner Dissertationsschrift literarische Werke, die reproduzierte Fotografien enthalten und in denen ein dialogisches Verhältnis zwischen Text und Bild zu verzeichnen ist. Aus vornehmlich literaturwissenschaftlicher Perspektive dokumentiert er die historische Entwicklung der Gattung Foto-Text von den Anfängen bis zum Gegenwartsroman und wirft einen intensiven und innovativen Blick auf das Wechselverhältnis zwischen Literatur und den in ihr enthaltenen Fotografien. Der in der Forschung bislang weniger beachtete Einfluss der Fotografien auf die Poetologie der Autoren Rolf Dieter Brinkmann, Alexander Kluge und W.G. Sebald wird von ihm deutlich gemacht und in klar verständlicher Form anhand eines großen Textkorpus, der sich im Wesentlichen auf die Werke der genannten drei Autoren erstreckt, erläutert.

Reference-less detection, astrometry, and photometry of faint companions with adaptive optics
Creators: name: Gladysz, Szymon

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms exploit the difference in statistics between the on-axis and off-axis intensity. Using moderate-Strehl ratio data obtained with the natural guide star adaptive optics system on the Lick Observatory's 3-m Shane Telescope, we compare these methods to the standard approach of PSF fitting. We give detection limits for the Lick system, as well as a first guide to expected accuracy of differential photometry and astrometry with the new techniques. The proposed approach to detection offers a new way of determining dynamic range, while the new algorithms for differential photometry and astrometry yield accurate results for very faint and close-in companions where PSF fitting fails. All three proposed algorithms are self-calibrating, i.e. they do not require observation of a calibration star thus improving the observing efficiency.

Textwissenschaft als Kulturwissenschaft
Creators: name: Schanze, Christoph
Publisher: name: KULT_online
Year: 2008

description: Der Münchner Mediävist und Kulturwissenschaftler Jan-Dirk Müller beschreibt in seinem Buch Höfische Kompromisse den Zusammenhang zwischen zentralen Themen der höfischen Epik und dem Fundus an Imaginärem, den die höfische Kultur bereitstellt. Dabei geht es um die "Konstitution des Helden in mittelalterlicher Epik [...] als Mitglied eines Kollektivs ([Kapitel] 1 und 2), als einzelne(r) (3 und 4), eingespannt zwischen der Öffentlichkeit des Hofs und der Verschlossenheit des Inneren (5 und 6) und als Liebender (7 und 8)" (S. 41). Der Verfasser verfolgt einen literaturwissenschaftlichen Ansatz, der unter Verwendung von Konzepten und Modellen der Kulturwissenschaften, zum Beispiel ,Herkunft/Genealogie‘, ,Ich-Welt-Bezug‘ oder ,Liebe und Gesellschaft‘, einen thematisch angelegten breiten Überblick über die höfische Epik ergibt.
