Innovation oder Wiederkehr? : Das Methodenspektrum im Kurzzeitgedächtnis der Literaturwissenschaft
(2011)
In recent years, a pronounced methodological self-reflexiveness has been established as a standard in studying language and literature. Methodological pluralism and a specific methodological adaptation to the objects of study are a characteristic feature of present-day literary and cultural studies. In keeping with this tendency, introductory textbooks on literary studies often provide an overview of the broad discussion and spectrum of methods and their seemingly boundless possible applications and the options for combining them. But this is not the first time that the boundaries of our discipline have undergone dissolution. Beginning with early examples of accounts of methodological variety and methodological reflection (Oscar Benda, Harry Maync, Emil Ermatinger, Julius Petersen), the present article discusses the ways in which an awareness of a surprisingly long tradition of discussions concerning methodological competence affects the present self-conception and identity of philology.
Based on the metaphor of “liminality” in literary studies, this paper examines two different approaches to the literary genre of travelogues, using the example of Adelbert von Chamisso‟s Voyage Around the World (1836). One approach, with the help of autobiographical research, sheds light on the author-specific key motifs of “omnipotent time” and the process of aging. In the second approach, the focus shifts to the relationship between literature and natural science, i.e. to Chamisso‟s transitional position in the context of the historicization and dynamization of the sciences and humanities in the 19th century. Rather than thinking of “philology” and “cultural studies” as opposing methods, this article thus suggests a more in-tercessory position for the purpose of a fruitful study of travel literature.
This paper examines the well-known practice of developing a conceptual frame-work for reading works of literature in such a way as to illuminate previously ignored aspects of those works. It investigates the nature or genre of such discoveries: Are they philological? Hermeneutic? Do they correspond to the discipline of the framework selected? This problem is considered in the case of an example of the deployment of a very specific philosophical framework, namely the problem of skepticism as glossed by the American philosopher Stanley Cavell. This framework brings to light a structural affinity between two seemingly disparate moments in the history of German lyric poetry: the Biedermeier period and the works of Konkrete Dichtung from the mid-twentieth century. The paper postulates this affinity as an exam-ple of the kind of “discovery” whose type, usefulness, or even existence as discovery might be called into question and perhaps not, ultimately, agreed on.
In works of Maghrebi authors like Tahar Ben Jelloun (Morocco), the body is the central medium that generates and constitutes the narration. The authors stand in the tradition of oral folk literature, which increasingly has been displaced by French written literature. Hence there is a tendency in postcolonial Maghrebi texts to reintegrate the performative act of narrating via the body into the literary structures of the novels. This becomes manifest in poly-phonic and poly-perspectival narrative experiments in which, with recourse to the halqa (the typical oral narrative situation), a re-territorialization (Deleuze/Guattari) of the body is performed.
In this context the body in literature plays a central role on the level of the metadiegesis: it is presented as the medium of narration. Using as an example Tahar Ben Jellouns novel L’enfant de sable (1985), the aim of this essay is to show how halqa elements and narrative influences from The Arabian Nights structure the text, which becomes a hybrid between medium and embodiment (Fischer-Lichte) by simulating eventfulness.
On the level of the diegesis, the body plays likewise a decisive role as subject of the storyline, becoming the most important medium for the expression of emotions, thoughts or attitudes. Body language is deliberately utilized by the authors to discuss ways of dealing with traditions, the negotiation of social relations and the (de-)construction of identity. Social order, power structures, hierarchies, existing values and norms are communicated and constituted via body language.
Is there something like a 'scientific' approach to the reading or interpretation of literary texts as is suggested by the German term 'Literaturwissenschaft'? This essay argues that genuinely scientific criteria such as the intersubjective verifiability of a given reading do not apply to the reading of literary texts. The reason is that such texts enable a quasi infinite range of different readings the preconceptions of which are contingent upon the individual readers, their previous experiences, literary as well as non-literary, and their expectations. — What, then, are the tasks of a scholarly reading of literary texts? Firstly, the theoretical reflection upon the status of such texts in comparison to pragmatic texts; secondly, the attempt at reconstructing their historical context (in terms of discursive history), and thirdly, a reading with regard to present-day problems. The 'quality' of a scholarly reading of a literary text would thus be dependent not on its 'objectivity', but rather on its capacity to produce resonances amongst other present-day readers, scholarly and non-scholarly.
This paper seeks to demonstrate the ways in which Bachmann's work constitutes a prime case for examining the scope and the boundaries of philological research. It does so by focusing on Bachmann‘s fragmentary and unfinished novel, "Das Buch Franza" [1965-1966], exploring the text and its author in an interdisciplinary light. Forming part of Bachmann's uncompleted "Todesarten"-Projekt, "Das Buch Franza" deals with the continuing legacy of fascism and its displaced forms in the post-war era. In its thematisation of the traumatic and necessarily belated after-effects of the Second World War and the Holocaust, Bachmann‘s text draws on various disciplines and discourses, namely geology, archaeology and psychoanalysis. I consider the ways in which the interdisciplinary ambitions of the text reflect Bachmann‘s struggle for a new form of representation, one that adequately mirrors the concerns of her society. Finally, drawing on Bachmann‘s own theoretical reflections on the field of literary study in her Frankfurt Lectures on poetics, I trace the ways in which the author's work repeatedly encourages us to adopt multiple disciplinary perspectives, as well as privileging literature with a utopian function that exceeds any generic or disciplinary boundaries.
The article engages in a close reading of Goethe's sonnet "Mächtiges Überraschen", published in the sonnet cycle of 1807. In it the poetic voice evokes a mountain river whose course is suddenly interrupted by the limiting force of a dam. Paradoxically, however, the effect of this is not stagnation, but the emergence and celebration of a "new life". This paradox will be illuminated by a discussion of Goethe's "Morphologie" as a universal scientific method. Morphology studies the infinite variety of (natural) forms while also insisting on their individual limitation. Goethe's understanding of life lingers on the co-presence of "coined form" and "living development" as he formulates it in "Urworte. Orphisch". "Mächtiges Überraschen" is read as a poem that embodies this fundamental polarity. The sonnet refers time and again to the borders and limitations of both the natural image it evokes and its own poetic properties. Simultaneously, it suggests the transgression of these limitations on both a formal (or structural) and a metaphorical level. As a poetological sonnet, "Mächtiges Überraschen" unifies the representation (of a natural event) with a reflection on representation as such. The announcement of a "new life" in the last stanza of the poem is thus read as an announcement of its own coming-into-being.
The essay raises the question of what it actually means to work with concepts of intermediality in literary studies. It uses as an example a Ph.D project which compares story-telling in literary texts and videographed testimonies by Shoah survivors. It soon becomes clear that that a strictly "intermedial" approach does not fully serve the purpose. Instead, one should try to maintain a literary studies perspective even on other forms of media. To illustrate this, the essay presents an analysis of videographed testimonies using categories taken from literary narratology. It thereby shows the problems as well as the merits of such an approach, at the limits of the discipline.
Friedrich August Wolf posits in his "Prolegomena ad Homerum" that, from the time of the first transcription of Homer's epics around 700 BC to the time of the Alexandrian editions, the Iliad and Odyssey underwent repeated revisions by a multitude of poets and critics. According to Wolf, the "unified" works that we know are the products of emendations by Alexandrian critics who attempted to homogenize the style of the epics and to return them to their "original" form. This paper argues that Wolf's narration of the history of these texts relies on and produces aesthetic claims, not historical ones. Wolf determines the dates and origins of passages based on intuitive judgments of style for which he cannot provide linguistic or historical evidence. And his conclusions that the "Iliad" and "Odyssey" were not written by Homer, but rather by a history of emendations and revisions, enthrones his work — the work of philologists — in place of the literary genius Homer. Thus philology becomes for Wolf an aesthetic discipline that produces canonical and beautiful works of literature. This aesthetic task is essential for philology to fulfill its educational and political responsibilities.
In response to the question "What is the nature of a philological practice that seeks to establish a spatial relationship between text and reader?" this essay compares the philologist Hans Ulrich Gumbrecht's contemporary account of aesthetic experience with the school of Empathy Aesthetics in the late nineteenth century with respect to the manner each emphasizes the spatial qualities of that relationship. Although employing different conceptual repertoires, both assert that the desire of an aesthetic recipient to be in the spatial vicinity of the object and experience the presence of the object with and upon his own body motivates an aesthetic experience, including the work of the philologist. Gumbrecht and the empathy aesthetician Robert Vischer characterize the desire to stand in a spatial relationship to the aesthetic object as the desire to be subsumed thereby, a characterization which entails the negation of the original philological standpoint.

Over the past two decades the “one drug – one target – one disease” concept became the prevalent paradigm in drug discovery. The main idea of this approach is the identification of a single protein target whose inhibition leads to a successful treatment of the examined disease. The predominant assumption is that highly selective ligands would avoid unwanted side effects caused by binding to secondary non-therapeutic targets. In recent years the results of post-genomic and network biology showed that proteins rarely act in isolated systems but rather as a part of a highly connected network [1]. In addition this connectivity leads to more robust systems that cannot be interfered by the inhibition of a single target of that network and consequently might not lead to the desired therapeutic effect [2]. Furthermore studies prove that robust systems are rather affected by weak inhibitions of several parts than by a complete inhibition of a single selected element of that system [3]. Therefore there is an increasing interest in developing drugs that take effect on multiple targets simultaneously but is concurrently a great challenge for medicinal chemists. There has to be a sufficient activity on each target as well as an adequate pharmacokinetic profile [4]. Early design strategies tried to link the pharmacophors of known inhibitors, however these methods often lead to high molecular weight and low ligand efficacy. We present a new rational approach based on a retrosynthetic combinatorial analysis procedure [5] on approved ligands of multiple targets. These RECAP fragments are used to design a large combinatorial library containing molecules featuring chemical properties of each ligand class. The molecules are further validated by machine learning models, like random forests and self-organizing maps, regarding their activity on the targets of interest.
The LANSCE linear accelerator at Los Alamos National Laboratory provides H− and H+ beams to several user facilities that support Isotope Production, NNSA Stockpile Stewardship, and Basic Energy Science programs. These beams are initially accelerated to 750 keV using Cockcroft-Walton (CW) based injectors that have been in operation for over 37 years. They have failure modes which can result in prolonged operational downtime due to the unavailability of replacement parts. To reduce long-term operational risks and to realize future beam performance goals in support of the Materials Test Station (MTS) and the Matter-Radiation Interactions in Extremes (MaRIE) Facility, plans are underway to develop a Radio-Frequency Quadrupole (RFQ) based front end as a modern injector replacement for the existing CW injectors. Our progress to date will be discussed.
Beam test of the direct plasma injection scheme (DPIS) is carried out successfully for the first time in China, by setting up a comprehensive test and research platform of RFQ and laser ion source. The C6+ beam is accelerated successfully, and the peak beam current reaches more than 6mA which is measured by a Faraday cup of unique structure. The RF power coupled into the RFQ cavity is also examined, and results reveal that it is the RF power of about 195kW that can produce the peak beam current.
Beam measurements with the new RFQ beam matching section at the Frankfurt Funneling Experiment
(2011)
Funneling is a method to increase low energy beam currents in multiple stages. The Frankfurt Funneling Experiment is a model of such a stage. The experiment is built up of two ion sources with electrostatic lens systems, a Two-Beam-RFQ accelerator, a funneling deflector and a beam diagnostic system. The two beams are bunched and accelerated in a Two-Beam RFQ. A funneling deflector combines the bunches to a common beam axis. A new beam transport system between RFQ accelerator and deflector has been constructed and mounted. With these extended RFQ-electrodes the drift between the Two-Beam-RFQ and the rf-deflector will be minimized and therefore unwanted emittance growth reduced. After first rf measurements current work are beam tests with the improved Two-Beam-RFQ. First results will be presented.
A CW RFQ prototype
(2011)
A short RFQ prototype was built for RF-tests of high power RFQ structures. We will study thermal effects and determine critical points of the design. HF-simulations with CST Microwave Studio and measurements were done. The cw-tests with 20 kW/m RF-power and simulations of thermal effects with ALGOR were finished successfully. The optimization of some details of the HF design is on focus now. First results and the status of the project will be presented.
"Finnegans Wake" has struck many of its exegetes as the epitome of the postmodern text. The oddity of James Joyce's last work has been and still is a provocation not only for literary criticism and theory but for every reader of the work. It provokes us to reflect on our preconceptions concerning such fundamental issues as reading, meaning and understanding. Due to this very quality, the work has been a fertile intellectual stimulus for an illustrious band of thinkers of the ―post-projects. Its singularity has provoked and facilitated the further development of theoretical frameworks beyond the confines of literary theory proper. This essay will trace the elaborate theoretical responses of Umberto Eco and Jacques Lacan to Joyce's grand literary arcanum. Eco's concept of the openness of modern works of art and Lacan's elaboration of his psychoanalytic concepts of the symptom and of the Borromean knot were inspired by their study of Joyce. As an extreme instance of literariness, Finnegans Wake thus constitutes an ideal opportunity to consider the scope and boundaries of the scholarly study of literary texts more generally.
Die Grenzen und Möglichkeiten der Philologie im Holocaust-Diskurs : das Beispiel Theresienstadt
(2011)
Philology seems to have come to a crossroads. One path leads back to the save haven of established core strengths and competences, the other path promises new perspectives through further expansion into the vastness of cultural studies. If philology is to continue as a discipline relevant to society as a whole, retreat into pure philology — concentrating only on the text itself, adhering to national boundaries — is no viable option. Instead, by opening itself up for the questions and methods of truly interdisciplinary inquiry, philology can emerge in new shape, powerful enough to adequately address issues of interdisciplinary, intercultural and intergenerational importance. This essay will argue for such an extension of philology into cultural studies through an examination of texts, songs and plays written in and about the Terezín ghetto. The songs of Leo Strauß and Manfred Greiffenhagen, the ghetto opera "Der Kaiser von Atlantis" (The Emperor of Atlantis), as well as Roy Kift's play "Camp Comedy" and Frido Mann's parable "Terezín" will exemplify the potential of philology’s conjunction with history, sociology and cultural studies.
Most texts that deal with Martin tom Dieck’s black-and-white comic "hundert Ansichten der Speicherstadt" (Zürich: Arrache Cœur, 1997, French title: Vortex) claim that it depicts the eponymous warehouse district (Speicherstadt) in Hamburg. As this paper shows, this claim is inaccurate: although the architecture in tom Dieck’s drawings clearly refers to buildings in the warehouse district, the differences in the details are so obvious, that to speak of a straightforward depiction of the Speicherstadt is oversimplifying. After a brief comparison with Christoph Schäfer’s picture book "Die Stadt ist unsere Fabrik" (Leipzig: Spector Books, 2010), the paper concludes with a discussion of the depiction of urban environments in general and in tom Dieck's book in particular.
Es ist eine alte Debatte. Auf der einen Seite steht die althergebrachte Maxime, alles, was wert ist, gesagt zu werden, müsse in jeder Sprache gesagt werden können - umso mehr dann, wenn es sich um die Wissenschaft handelt, die den Anspruch erhebt, universelle Wahrheiten zu erfassen. Demgegenüber steht ein immer wieder anzutreffender Gedanke, dessen wohl inspirierteste Formulierung von Wilhelm von Humboldt stammt, nämlich, dass die Verschiedenheit der Sprachen nicht nur eine von „Schällen und Zeichen“, sondern eine der „Weltansichten selbst“ sei. Thema dieses Vortrags ist die Frage, wo die Wahrheit zwischen diesen scheinbaren Gegensätzen liegt.
Die Antike bildet einen zentralen Bezugspunkt für Identitätskonstruktionen in den europäischen Kulturen. Das Wissen davon, was Antike ist, ist jedoch keineswegs statisch: "Die Antike" formiert sich historisch stets im Wechselspiel mit dem Selbstverständnis der rezipierenden Kulturen. Diese bipolare Konstruktion griff die interdisziplinäre Tagung "Das Geschlecht der Antike" auf, die Anna Heinze (Berlin) und Friederike Krippner (Berlin) im Juni an der Humboldt-Universität zu Berlin veranstalteten. Sie verfolgte einerseits die Frage, welche Rolle die Kategorie "Geschlecht" bei verschiedenen Epochenentwürfen der Antike spielt, und richtete den Blick andererseits darauf, was die Referenz auf die Antike bei der Konstruktion von Geschlechterverhältnissen in nachantiken Gesellschaften leistet.
Im Jahr 2006 brachte Saul Friedländer seine weithin beachtete Gesamtdarstellung „Nazi Germany and the Jews“ mit dem zweiten Band „The Years of Extermination“ zum Abschluss. Das Buch lese sich wie ein Roman, so und ähnlich urteilten Rezensenten über dessen literarische Qualitäten. Auf erzählerische Stärken verweisen auch Kommentare zu Christopher Brownings jüngster Studie „Remembering Survival“ (2010). Das Erzählen in der Geschichtswissenschaft ist seit längerem wieder Gegenstand der Diskussion: Forscherinnen und Forscher auf einem Symposium auf dem Alten Schloss Dornburg bei Jena gingen im Juni 2011 dieser Frage speziell für den Bereich der Holocaust-Historiographie nach.
Meeting Abstract : 82. Jahresversammlung der Deutschen Gesellschaft für Hals-Nasen-Ohren-Heilkunde, Kopf- und Hals-Chirurgie. Freiburg i. Br., 01.-05.06.2011.
Ca. 3 Millionen Erwachsene in der Bundesrepublik Deutschland leiden unter Tinnitus, wobei eine bei jedem dieser Patienten zur Heilung führende Therapie bisher noch nicht existiert. Ansatzpunkt einer neuartigen Therapie ist die Wiederherstellung des normalen elektrischen Entladungsmusters im Hörnerv mittels elektrischer Stimulation. Hiermit berichten wir über unsere ersten Erfahrungen mit dem Tinnelec, einem Implantat mit einer einzelnen Stimulations-Elektrode die in der Rundfensternische platziert wird.
Zurzeit haben wir 4 einseitig ertaubten Patienten mit Tinnitus auf dem betroffenen Ohr jeweils ein Tinnelec-System implantiert. Die Dauer des Tinnitus betrug mindestens ein Jahr und gängige Tinnitus-Therapien wie z.B. Infusionstherapie waren erfolglos geblieben. Ein psychogener Tinnitus wurde ausgeschlossen. Der durch den Tinnitus verursachte Leidensdruck wurde anhand einer VAS Scala (Visuelle Analog Scala) und eines Tinnitus-Handicap-Inventory (THI) Fragebogens beurteilt. Die Reizapplikation betrug mind. 4 Stunden täglich. Als Stimulationsparameter wurde eine Reizmusterannäherung an den Tinnitus angestrebt.
Bei drei Patienten wurde unter der Stimulation der Tinnitus erträglicher, eine zeitweise komplette Unterdrückung des Tinnitus schon innerhalb der ersten Therapie-Wochen wurde jedoch nur in einem der Fälle berichtet. Diese Ergebnisse wurden auch durch das THI und VAS unterstützt.
Die Tinnelec-Implantation erscheint für Tinnitus Erfolg versprechend zu sein. Weitere Studien bei Tinnitus-Patienten ohne zusätzliche Hörbeeinträchtigung sind jedoch notwendig bis endgültige Schlussfolgerungen betreffend dieses Implantats gezogen werden können. In jedem Fall bleibt die Option einer Cochlea-Implantation im selben Ohr, nach Explantation des Tinnelec, bestehen.
Accelerator Driven Systems (ADS) are promising tools for the efficient transmutation of nuclear waste products in dedicated industrial installations, called transmuters. The Myrrha project at Mol, Belgium, placed itself on the path towards these applications with a multipurpose and versatile system based on a liquid PbBi (LBE) cooled fast reactor (80 MWth) which may be operated in both critical and subcritical modes. In the latter case the core is fed by spallation neutrons obtained from a 600 MeV proton beam hitting the LBE coolant/target. The accelerator providing this beam is a high intensity CW superconducting linac which is laid out for the highest achievable reliability. The combination of a parallel redundant and of a fault tolerant scheme should allow obtaining an MTBF value in excess of 250 hours that is required for optimal integrity and successful operation of the ADS. Myrrha is expected to be operational in 2023. The forthcoming 4-year period is fully dedicated to R&D activities, and in the field of the accelerator they are strongly focused on the reliability aspects and on the proper shaping of the beam trip spectrum.
Chromatic, geometric and space charge effects on laser accelerated protons focused by a solenoid
(2011)
We studied numerically emittance and transmission effects by chromatic and geometric aberrations, with and without space charge, for a proton beam behind a solenoid in the laser proton experiment LIGHT at GSI. The TraceWin code was employed using a field map for the solenoid and an initial distribution with exponential energy dependence close to the experiment. The results show a strong effect of chromatic, and a relatively weak one of geometric aberrations as well as dependence of proton transmission on distance from the solenoid. The chromatic effect has an energy filtering property due to the finite radius beam pipe. Furthermore, a relatively modest dependence of transmission on space charge is found for p production intensity below 1011.
n order to reach the desired intensities of heavy ion beams for the experiments at FAIR, SIS18 and SIS100 have to be operated with intermediate charge states. Operation with intermediate charge state heavy ions at the intensity level of about 1011 ions per cycle has never been demonstrated elsewhere and requires a dedicated upgrade program for SIS18 and a dedicated machine design for SIS100. The specific problems coming along with the intermediate charge state operation in terms of charge exchange processes at collisions with residual gas atoms, pressure bumps by ion induced desorption and corresponding beam loss appears far below the typical space charge limits. Thus, new design concepts and new technical equipment addressing these issues are developed and realized with highest priority. The upgrade program of SIS18 addressing the goal of minimum ionization beam loss and stable residual gas pressure conditions has been defined in 2005. A major part of this upgrade program has been successfully realized, with the result of a world record in accelerated number of intermediate charge state heavy ions.

How critical is criticality?
(2011)
Vom 17. bis 19. Februar 2011 luden Jens Eder, Joseph Imorde und Maike Sarah Reinerth für die Filmwissenschaft / Mediendramaturgie der Universität Mainz und die Kunstgeschichte der Universität Siegen Forscher und Forscherinnen unterschiedlicher Disziplinen zu einem Workshop mit dem Thema "Medium Menschenbild" ein. Förderer waren der Forschungsschwerpunkt "Medienkonvergenz" der Johannes Gutenberg-Universität Mainz und das Labor Neue Kunst Siegen. Ziel der Tagung war, das grundsätzliche Verhältnis von Medialität und Menschenbild zu analysieren, die Spezifik medial vermittelter Menschenbilder im interdisziplinären Austausch zu diskutieren sowie auf die in ihnen implizit enthaltenen konzeptuellen Vorstellungen hinzuweisen. ...

We review our knowledge of the phase diagram of QCD as a function of temperature, chemical potential and quark masses. The presence of tricritical lines at imaginary chemical potential m = i p 3 T, with known scaling behaviour in their vicinity, puts constraints on this phase diagram, especially in the case of two light flavors. We show first results in our project to determine the finite-temperature behaviour in the Nf = 2 chiral limit.
We explore the shape and orientation of the freezeout region of non-central heavy ion collisions.
For this we fit the freezeout distribution with a tilted ellipsoid. The resulting tilt angle is compared
to the same tilt angle extracted via an azimuthally sensitive HBT analysis. This allows to access
the tilt angle experimentally, which is not possible directly from the freezeout distribution. We
also show a systematic study on the system decoupling time dependence on dNch/dh, using HBT
results from the UrQMD transport model. In this study we found that the decoupling time scales
with (dNch/dh)1/3 within each energy, but the scaling is broken across energies.
We analyze general convergence properties of the Taylor expansion of observables to finite chemical potential in the framework of an effective 2+1 flavor Polyakov-quark-meson model. To compute the required higher order coefficients a novel technique based on algorithmic differentiation has been developed. Results for thermodynamic observables as well as the phase structure obtained through the series expansion up to 24th order are compared to the full model solution at finite chemical potential. The available higher order coefficients also allow for resummations, e.g. Padé series, which improve the convergence behavior. In view of our results we discuss the prospects for locating the QCD phase boundary and a possible critical endpoint with the Taylor expansion method.
This article presents a multiscale approach for detecting and monitoring soil erosion phenomena (i.e. gully erosion) in the agro-industrial area around the city of Taroudannt, Souss basin, Morocco. The study area is characterized as semi-arid with an annual average precipitation of 200 mm. Water scarcity, high population dynamics and changing land use towards huge areas of irrigation farming present numerous threats to sustainability. The agro-industry produces citrus fruits and vegetables in monocropping, mainly for the European market. Badland areas strongly affected by gully erosion border the agricultural areas as well as residential areas. To counteract the significant loss of land, land-leveling measures are attempted to create space for plantations and greenhouses. In order to develop sustainable approaches to limit gully growth the detection and monitoring of gully systems is fundamental. Specific gully sites are monitored with unmanned aerial vehicle (UAV) taking small-format aerial photographs (SFAP). This enables extremely high-resolution analysis (SFAP resolution: 2-10 cm) of the actual size of the gully channels as well as a detailed continued surveillance of their growth. Transferring the methodology on a larger scale using Quickbird satellite data (resolution: 60 cm) leads to the possibility of a large-scale analysis of the whole area around the city of Taroudannt (Area extent: ca. 350 km²). The results will then reveal possible relationships of gully growth and agro-industrial management and may even illustrate further interdependencies. The main objective is the identification of areas with high gully-erosion risk due to non-sustainable land use and the development of mitigation strategies for the study area.
Recently, new soil data maps were developed, which include vertical soil properties like soil type. Implementing those into a multilayer Soil-Vegetation-Atmosphere-Transfer (SVAT) scheme, discontinuities in the water content occur at the interface between dissimilar soils. Therefore, care must be taken in solving the Richards equation for calculating vertical soil water fluxes. We solve a modified form of the mixed (soil water and soil matric potential based) Richards equation by subtracting the equilibrium state of soil matrix potential ψE from the hydraulic potential ψh. The sensitivity of the modified equation is tested under idealized conditions. The paper will show that the modified equation can handle with discontinuities in soil water content at the interface of layered soils.
We report on the first steps of an ongoing project to add gauge observables and gauge corrections
to the well-studied strong coupling limit of staggered lattice QCD, which has been shown earlier
to be amenable to numerical simulations by the worm algorithm in the chiral limit and at finite
density. Here we show how to evaluate the expectation value of the Polyakov loop in the framework
of the strong coupling limit at finite temperature, allowing to study confinement properties
along with those of chiral symmetry breaking. We find the Polyakov loop to rise smoothly, thus
signalling deconfinement. The non-analytic nature of the chiral phase transition is reflected in the
derivative of the Polyakov loop. We also discuss how to construct an effective theory for non-zero
lattice coupling, which is valid to O(b).
On behalf of myself and my colleagues Professor Dr. Klaus Günther and Professor Dr. Lorenz Schulz, it is my great pleasure to welcome you to the 25th World Congress of the International Association for Philosophy of Law and Social Philosophy (IVR) in Frankfurt am Main. ...
QCD at finite temperature and denisty remains intractable by Monte Carlo simulations for quark
chemical potentials m >∼T. It has been a long standing problem to derive effective theories from
QCD which describe the phase structure of the former with controlled errors. We propose a
solution to this problem by a combination of analytical and numerical methods. Starting from
lattice QCD with in Wilson’s formulation, we derive an effective action in terms of Polyakov
loops by means of combined strong coupling and hopping expansions. The theory correctly
reflects the centre-symmetry in the pure gauge limit and its breaking through quarks. It is valid
for heavy quarks and lattices up to Nt ∼ 6. Its sign problem can be solved and we are able to
calculate the deconfinement transition of QCD with heavy quarks for all chemical potentials.
LatticeQCD using OpenCL
(2011)
We analyze the universal critical behavior at the chiral critical point in QCD with three degenerate quark masses. We confirm that this critical point lies in the universality class of the three dimensional Ising model. The symmetry of the Ising model, which is Z(2), is not directly realized in the QCD Hamiltonian. After making an ansatz for the magnetization- and energy-like operators as linear admixtures of the chiral condensate and the gluonic action, we determine several non-universal mixing and normalization constants. These parameters determine an unambiguous mapping of the critical behavior in QCD to that of the 3d-Ising model. We verify its validity by showing that the thus obtained orderparameter scales in accordance with the magnetic equation of state of the 3d-Ising model.
From 12.12.2010 to 17.12.2010, the Dagstuhl Seminar 10501 "Advances and Applications of Automata on Words and Trees" was held in Schloss Dagstuhl - Leibniz Center for Informatics.

This volume contains the abstracts of all oral and poster presentations of the international scientific conference „Sustainable Consumption – Towards Action and Impact“ held in Hamburg (Germany) on November 6th-8th 2011. This unique conference aims to promote a comprehensive academic discourse on issues concerning sustainable consumption and brings together scholars from a wide range of academic disciplines.
In modern societies, private consumption is a multifaceted and ambivalent phenomenon: it is a ubiquitous social practice and an economic driving force, yet at the same time, its consequences are in conflict with important social and environmental sustainability goals. Finding paths towards “sustainable consumption” has therefore become a major political issue. In order to properly understand the challenge of “sustainable consumption”, identify unsustainable patterns of consumption and bring forward the necessary innovations, a collaborative effort of researchers from different disciplines is needed.
