description: We study the Josephson current through a ballistic normal metal layer of thickness $D$ on which two superconducting electrodes are deposited within a distance $L$ of each other. In the presence of an ({\it in-layer}) magnetic field we find that the oscillations of the critical current $I_c(Φ)$ with the magnetic flux $Φ$ are significantly different from an ordinary magnetic interference pattern. Depending on the ratio $L/D$ and temperature, $I_c(Φ)$-oscillations can have a period smaller than flux quantum $Φ_0$, nonzero minima and damping rate much smaller than $1/Φ$. Similar anomalous magnetic interference pattern was recently observed experimentally.

description: Autonomous feeding is challenging because it requires manipulation of food items with various compliance, sizes, and shapes. To understand how humans manipulate food items during feeding and to explore ways to adapt their strategies to robots, we collected a rich dataset of human trajectories by asking them to pick up food and feed it to a mannequin. From the analysis of the collected haptic and motion signals, we demonstrate that humans adapt their control policies to accommodate to the compliance and shape of the food item being acquired. We propose a taxonomy of manipulation strategies for feeding to highlight such policies. As a first step to generate compliance-dependent policies, we propose a set of classifiers for compliance-based food categorization from haptic and motion signals. We compare these human manipulation strategies with fixed position-control policies via a robot. Our analysis of success and failure cases of human and robot policies further highlights the importance of adapting the policy to the compliance of a food item.

description: Zusammenfassung Im Jahre 1789 hatte Alexander von Humboldt als Student in Göttingen mit großem Enthusiasmus ein Manuskript zur „Weberei der Alten“ verfasst. Es war das Ziel seiner Studie, die Technologie und die Terminologie der antiken Weberei zu erfassen und beide Gebiete vereint darzustellen. Dieses Manuskript ist nicht veröffentlicht worden und gilt als verschollen. Alexander von Humboldt hatte offenbar neue Erkenntnisse gewonnen, denen er so große Bedeutung beimaß, dass er den Verlust seines Manuskriptes noch über 50 Jahre nach dessen Abfassung bedauerte. Humboldt benennt glücklicherweise in überlieferten Briefen verschiedene Grundgedanken seiner damaligen Arbeit. In der vorliegenden Studie wird unter Einbeziehung aktueller technikhistorischer Erkenntnisse nachgewiesen, dass der junge Alexander von Humboldt das für alle Webtechniken gültige Prinzip in seinen Grundzügen erkannt hatte. Resumen En 1789 Alexander von Humboldt, aún como estudiante en Göttingen, escribió con gran entusiasmo un manuscrito sobre la “Tejeduría en la Antigüedad Clásica”. El objetivo de su estudio era comprender la tecnología y la terminología en uso referente al arte de tejer, para presentar ambas áreas en su relación. Este manuscrito no ha sido publicado y se considera perdido. Al parecer, Alexander von Humboldt había adquirido nuevas ideas que iban más allá del objetivo original de su investigación, las cuales consideraba tan importantes, que lamentó perder su manuscrito más de 50 años después de haberlo redactado. Afortunadamente, Humboldt enumeró varias de las ideas principales de su trabajo en cartas. En el presente estudio, que incluye conocimientos actuales de la historia de la técnica, se demuestra que el joven Alexander von Humboldt había reconocido el principio básico de generalización que se aplica a todas las técnicas de la tejeduría. Abstract When Alexander von Humboldt was studying at Göttingen University, in 1789 he wrote an essay on “Weaving in the Ancient World”, a subject he tackled with great enthusiasm. His aim was to understand both, the technology and the terminology of ancient weaving. However, the essay has never been published and is believed to have been lost. He considered his findings to be so important that he regretted this loss even 50 years later. Fortunately, in some of his letters, Alexander von Humboldt mentioned the basic concepts which he wrote about in his essay on weaving. In the present study, including todayʼs knowledge of technical history, it is demonstrated that the young Alexander had recognized the general principles that apply to all weaving techniques.

description: English Summary
Research software is commonly used in various disciplines to perform research and as a research object itself. Therefore, it is covered by multiple NFDI consortia. To fulfill the FAIR criteria for research software, it needs to be described with meaningful and interoperable metadata enhancing transparency, reproducibility, and reusability in research. While there exist some metadata schemes for research software, e.g., CodeMeta, they have some limitations, e.g., missing elements and missing semantic interoperability.
To address these issues, this working group aims to provide a comprehensive metadata vocabulary for research software, compatible with existing frameworks such as schema.org and CodeMeta. Also, the working group will support all NFDI consortia in applying the vocabulary as well as develop domain-specific extensions if needed.
German Summary
Forschungssoftware wird in vielen Bereichen der Wissenschaft zur Forschung genutzt und stellt teilweise selbst ein Forschungsobjekt dar. Viele NFDI-Konsortien decken Forschungssoftware als wichtiges Forschungsartefakt mit ab und wollen, dass Forschungssoftware in Zukunft die FAIR-Kriterien erfüllt, um die Transparenz, Reproduzierbarkeit und Wiederverwendbarkeit in software-basierter Forschung zu erhöhen. Damit Forschungssoftware die FAIR-Kriterien erfüllt, muss sie mit aussagekräftigen und interoperablen Metadaten beschrieben werden. Dafür werden entsprechende Metadatenschemata benötigt. Es gibt zwar einige Metadatenschemata für Forschungssoftware, z. B. CodeMeta, aber sie weisen einige Einschränkungen auf, z. B. fehlende Elemente und fehlende semantische Interoperabilität. Um diese Probleme zu beheben, hat sich diese Arbeitsgruppe zum Ziel gesetzt, ein umfassendes Metadatenvokabular für Forschungssoftware bereitzustellen, das mit bestehenden Standards wie schema.org und CodeMeta kompatibel ist. Damit wird die Arbeitsgruppe alle NFDI-Konsortien bei der Anwendung und Etablierung von Metadatenschemeta für Forschungssoftware unterstützen, z.B. bei Entwicklung von bereichsspezifischen Erweiterungen.

description: Cosmic rays are thought to escape their sources streaming along the local magnetic field lines. We show that this phenomenon generally leads to the excitation of both resonant and non-resonant streaming instabilities. The self-generated magnetic fluctuations induce particle diffusion in extended regions around the source, so that cosmic rays build up a large pressure gradient. By means of two-dimensional (2D) and three-dimensional (3D) hybrid particle-in-cell simulations, we show that such a pressure gradient excavates a cavity around the source and leads to the formation of a cosmic-ray dominated bubble, inside which diffusivity is strongly suppressed. Based on the trends extracted from self-consistent simulations, we estimate that, in the absence of severe damping of the self-generated magnetic fields, the bubble should keep expanding until pressure balance with the surrounding medium is reached, corresponding to a radius of $\sim 10-50$ pc. The implications of the formation of these regions of low diffusivity for sources of Galactic cosmic rays are discussed. Special care is devoted to estimating the self-generated diffusion coefficient and the grammage that cosmic rays might accumulate in the bubbles before moving into the interstellar medium. Based on the results of 3D simulations, general considerations on the morphology of the $γ$-ray and synchrotron emission from these extended regions also are outlined.

description: Enzymatically induced calcite precipitation (EICP) in porous media can be used as an engineering option to achieve precipitation in the pore space, for example, aiming at a targeted sealing of existing flow paths. This is accomplished through a porosity and consequent permeability alteration. A major source of uncertainty in modeling EICP is in the quantitative description of permeability alteration due to precipitation. This report presents methods for investigating experimentally the time‐resolved effects of growing precipitates on porosity and permeability on the pore scale, in a poly‐di‐methyl‐siloxane microfluidic flow cell. These methods include the design and production of the microfluidic cells, the preparation and usage of the chemical solutions, the injection strategy, and the monitoring of pressure drops for given fluxes for the determination of permeability. EICP imaging methods are explained, including optical microscopy and X‐ray microcomputed tomography (XRCT), and the corresponding image processing and analysis. We present and discuss a new experimental procedure using a microfluidic cell, as well as the general perspectives for further experimental and numerical simulation studies on induced calcite precipitation. The results of this study show the enormous benefits and insights achieved by combining both light microscopy and XRCT with hydraulic measurements in microfluidic chips. This allows for a quantitative analysis of the evolution of precipitates with respect to their size and shape, while monitoring their influence on permeability. We consider this to be an improvement of the existing methods in the literature regarding the interpretation of recorded data (pressure, flux, and visualization) during pore morphology alteration.

description: Based on recent work on nuclear binding, we update and extend the anthropic constraints on the light quark masses, with results that are more tightly constrained than previously obtained. We find that heavy nuclei would fall apart (because the attractive nuclear central potential becomes too weak) if the sum of the light quark masses m_u+m_d would exceed their physical values by 64% (at 95% confidence level). We summarize the anthropic constraints that follow from requiring the existence both of heavy atoms and of hydrogen. With the additional assumption that the quark Yukawa couplings do not vary, these constraints provide a remarkably tight anthropic window for the Higgs vacuum expectation value: 0.39 < v/v_physical < 1.64.

Humboldts Eskorte. Kontrolle und Sicherheit auf Alexander von Humboldts Russlandreise 1829
Creators: name: Böttcher, Hendrik

description: Zusammenfassung Auf seiner Russlandexpedition von 1829 wurde Alexander von Humboldt fast durchgängig von Sicherheitskräften der Regierung begleitet. Die Forschung wies dieser Eskorte bisher vor allem eine Kontrollfunktion zu. Im Folgenden wird gezeigt, dass Humboldts bewaffnete Begleiter wahrscheinlich weniger der Überwachung, als der Absicherung seiner Expedition dienten. Der Artikel wirft dafür einen Blick auf die Sicherheitslage im Umfeld der Russlandreise, die Eskorte an sich sowie ihre letztendlich eng begrenzten Möglichkeiten zur Kontrolle des Wissenschaftlers. An Material stehen dafür unter anderem Humboldts Reisekorrespondenz, der Reisebericht seines Gefährten Gustav Rose und die erst jüngst veröffentlichten Tagebücher Christian Gottfried Ehrenbergs zur Verfügung. Abstract During his expedition to Russia in 1829, Alexander von Humboldt was almost constantly accompanied by government security forces. Studies in the past have usually seen this escort as an attempt to control the liberal researcher. This article shows that his armed company was probably meant to protect Humboldt rather than to supervise him. Therefore, the article analyzes potential threats on the route of the expedition, how the escort adapted to them and how far the guards would have been able to control him anyway. The most important sources are Humboldt's written communication, the travel account by his friend Gustav Rose and the recently published diaries of his companion Christian Gottfried Ehrenberg. Resumen Durante su expedición a Rusia en 1829, Alexander von Humboldt estuvo acompañado casi en todo momento por fuerzas de seguridad del gobierno. La literatura científica interpreta este dato, normalmente, como un intento de control hacia el investigador liberal. En contraposición, el presente artículo sugiere que la compañía armada de Humboldt servía probablemente más como protección del viajero. Para demostrarlo analiza las posibles amenazas que podían haber sucedido en el camino de la expedición, las reacciones de la escolta y por la otra parte sus limitadas capacidades de control. Los correos del mismo Humboldt resultan ser las fuentes más importantes de esta investigación, en las cuales se focaliza, así como los relatos de su compañero Gustav Rose y los muy recientemente publicados diarios de Christian Gottfried Ehrenberg.

description: Zusammenfassung In dem vorliegenden Beitrag geht der Verfasser von seinen Gesprächen aus, die er mit seinem Kollegen Michaeler in der Zeit von 1976 bis 1985 an der Universidad Incca de Colombia führen konnte. Dabei bezieht er die ihm – von Michaeler vor seinem Tod – übergebenen biografischen Daten mit ein. Insgesamt sollen die Ausführungen zum Weiterdenken anregen. Der Beitrag geht von der vielfältigen klimatischen und archäologischen Landschaft Kolumbiens aus und verbindet dies mit der damaligen Wissenschaftskonzeption an der Universidad Incca de Colombia. In diesem Kontext wird u. a. auf das Werk von Ernst Bloch „Das Prinzip Hoffnung“ und die Arbeit von Hans Jonas „Das Prinzip Verantwortung“ Bezug genommen. Für Michaeler waren die Werke der Brüder Humboldt, die Schrift Kants „Zum ewigen Frieden“, die Dialektik Hegels und die Gesellschaftstheorie von Marx in der Universitätsausbildung unverzichtbar. Resumen En este artículo el autor toma como punto de partida las conversaciones que tuvo con su colega Michaeler en la Universidad Incca de Colombia entre 1976 y 1985. Tiene en cuenta los datos biográficos que le entregó Michaeler antes de su muerte. En general, las explicaciones tienen la intención de estimular la reflexión. La contribución toma como punto de partida el diverso paisaje climático y arqueológico de Colombia y lo vincula con la concepción de la ciencia en ese momento en la Universidad Incca de Colombia. En este contexto, se hace referencia a la obra de Ernst Bloch “El principio de la esperanza” y a la obra de Hans Jonas “El principio de la responsabilidad”. Para Michaeler, las obras de los hermanos Humboldt, el “Zum ewigen Frieden” de Kant, la dialéctica de Hegel y la teoría social de Marx eran indispensables en la educación universitaria. Abstract In this article the author takes as his starting point the discussions, he had with his colleague Michaeler at the Universidad Incca de Colombia between 1976 and 1985. He takes the biographical data handed over to him by Michaeler before his death into account. All in all, the explanations are intended to stimulate further thinking. The contribution takes Colombiaʼs diverse climatic and archaeological landscape as its starting point and links this to the conception of science at that time at the Universidad Incca de Colombia. In this context, reference is made to the work of Ernst Bloch “The Principle of Hope” and the work of Hans Jonas “The Principle of Responsibility”. For Michaeler, the works of the Humboldt brothers, Kantʼs “Zum ewigen Frieden”, the dialectic of Hegel and the social theory of Marx were indispensable in university education.

Considérations sur l’atmosphère des tropiques… – un mémoire inédit d’Alexander von Humboldt

description: Résumé L’article contient l’édition critique d’un mémoire d’Alexander von Humboldt, intitulé: «Considérations sur l’atmosphère des tropiques, regardée comme objet de la pathologie chimique». Le texte a été écrit à Cuba, en 1801. Il fait partie d’un groupe de manuscrits, relatifs à la qualité de l’air dans les tropiques et aux maladies qui en découlent, portant un titre général: «C’est mon cahier de la Havanne intitulé sur la salubrité de l’air». Or A. v. Humboldt partageait alors les vues miasmatiques et il voyait, dans la qualité de l’air, l’origine des maladies que l’on dit aujourd’hui «infectieuses». L’accent y est posé sur la fièvre jaune qui occupait une place particulière dans l’horizon intellectuel et politique du début du XIXe siècle. Reste à ajouter que Humboldt se montre ici comme l’un des précurseurs de l’écologie moderne. Zusammenfassung Der Beitrag liefert eine kritische Ausgabe des 1801 auf Kuba niedergeschriebenen Textes Alexander von Humboldts unter dem Titel „Considérations sur l’atmosphère des tropiques, regardée comme objet de la pathologie chimique“. Er wird in der Mappe mit Humboldts Handschriften zu der Luftqualität in den Tropen und den daraus resultierenden Krankheiten aufbewahrt, die von dem Gelehrten mit der Aufschrift „Cʼest mon cahier de la Havanne intitulé sur la salubrité de lʼair“ identifiziert wurde. Zur Zeit der Entstehung des Manuskripts war Alexander von Humboldt Anhänger der Miasmentheorie und erkannte in der Luftqualität den Ursprung der Krankheiten, die heutzutage als „ansteckend“ bezeichnet werden. Der Text konzentriert sich vor allem auf das Gelbfieber und somit auf eine Krankheit, die einen wichtigen Platz im geistigen und politischen Horizont der ersten Jahrzehnte des 19. Jahrhunderts einnahm. Er lässt die Leistung Alexander von Humboldts als Vorläufer der modernen Ökologie erkennen. Abstract The article contains the critical edition of Alexander von Humboldtʼs text “Considérations sur l’atmosphère des tropiques, regardée comme objet de la pathologie chimique”, created in Cuba, in 1801. The text can be found in a group of manuscripts referring to the quality of the air in the tropics and to diseases that result from it; those manuscripts have a general title: “C’est mon cahier de la Havanne intitulé sur la salubrité de l’air”. A. v. Humboldt shared miasmatic views at that time and in the quality of the air he saw the cause of diseases called «infectious» nowadays . The emphasis is placed on yellow fever, which occupied a prominent place in intellectual and political horizons at the beginning of 19th century. It remains to be added that Humboldt writes here as a precursor of modern ecology.

Information‐Based Machine Learning for Tracer Signature Prediction in Karstic Environments

name: Oppel, H.

name: Hartmann, A.
Publisher: name: FID GEO
Year: 2020

description: Karstic groundwater systems are often investigated by a combination of environmental or artificial tracers. One of the major downsides of tracer‐based methods is the limited availability of tracer measurements, especially in data sparse regions. This study presents an approach to systematically evaluate the information content of the available data, to interpret predictions of tracer concentration from machine learning algorithms, and to compare different machine learning algorithms to obtain an objective assessment of their applicability for predicting environmental tracers. There is a large variety of machine learning approaches, but no clear rules exist on which of them to use for this specific problem. In this study, we formulated a framework to choose the appropriate algorithm for this purpose. We compared four different well‐established machine learning algorithms (Support Vector Machines, Extreme Learning Machines, Decision Trees, and Artificial Neural Networks) in seven different karst springs in France for their capability to predict tracer concentrations, in this case SO42− and NO3−, from discharge. Our study reveals that the machine learning algorithms are able to predict some characteristics of the tracer concentration, but not the whole variance, which is caused by the limited information content in the discharge data. Nevertheless, discharge is often the only information available for a catchment, so the ability to predict at least some characteristics of the tracer concentrations from discharge time series to fill, for example, gaps or increase the database for consecutive analyses is a helpful application of machine learning in data sparse regions or for historic databases.
description: Key Points: Application of entropy and mutual information reveals the information content gap between discharge derived from joint tracer and discharge analyses. Understanding the information content of hydrological data enhances the interpretation of machine learning prediction results. Similarities in information could be used for regionalization of catchment characteristics of karst‐affected catchments.

description: The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This multi-purpose high-contrast visible and near-infrared (R- to K-band) instrument is not only intended to serve as a VLT-class "planet-imager" instrument in the Northern hemisphere, but also to operate as a technology demonstration testbed ahead of the ELTs-era, with a particular emphasis on small inner-working angle (IWA) coronagraphic capabilities. The given priority to small-IWA imaging led to the early design choice to incorporate focal-plane phase-mask coronagraphs. In this context, a test H-band vector vortex liquid crystal polymer waveplate was provided to SCExAO, to allow a one-to-one comparison of different small-IWA techniques on the same telescope instrument, before considering further steps. Here we present a detailed overview of the vector vortex coronagraph, from its installation and performances on the SCExAO optical bench, to the on-sky results in the extreme AO regime, as of late 2016/early 2017. To this purpose, we also provide a few recent on-sky imaging examples, notably high-contrast ADI detection of the planetary-mass companion κAndromedae b, with a signal-to-noise ratio above 100 reached in less than 10 mn exposure time.

description: Solar twins are stars of key importance to the field of astronomy and offer a multitude of science applications. Only a small number ($\lesssim200$) of solar twins are known today, all of which are relatively close to our Sun ($\lesssim800\,pc$). The goal of our Survey for Distant Solar Twins (SDST) is to identify many more solar twin and solar analogue stars out to much larger distances ($\sim4\,kpc$). In this paper, we present a new method to identify solar twins using relatively low $S/N$, medium resolving power ($R\sim 28{,}000$) spectra that will be typical of such distant targets observed with HERMES on the $3.9\,m$ Anglo-Australian Telescope (AAT). We developed a novel approach, namely EPIC, to measure stellar parameters which we use to identify stars similar to our Sun. EPIC determines the stellar atmospheric parameters (effective temperature $T_{\mathrm{eff}}$, surface gravity $\log g$ and metallicity [Fe/H]) using differential equivalent width (EW) measurements of selected spectroscopic absorption features and a simple model, trained on previously analysed spectra, that connects these EWs to the stellar parameters. The reference for the EW measurements is a high $S/N$ solar spectrum which is used to minimise several systematic effects. EPIC is fast, optimised for Sun-like stars and yields stellar parameter measurements with small enough uncertainties to enable spectroscopic identification of solar twin and analogue stars up to $\sim4\,kpc$ away using AAT/HERMES, i.e.\ $σ\left(T_{\mathrm{eff}}, \log g, \textrm{[Fe/H]}\right) = \left(50\,K, 0.08\,dex, 0.03\,dex\right)$ on average at $S/N=25$.

description: We present the first measurements of the angular correlation function of galaxies selected in the far (1530 A) and near (2310 A) Ultraviolet from the GALEX survey fields overlapping SDSS DR5 in low galactic extinction regions. The area used covers 120 sqdeg (GALEX - MIS) down to magnitude AB = 22, yielding a total of 100,000 galaxies. The mean correlation length is ~ 3.7 \pm 0.6 Mpc and no significant trend is seen for this value as a function of the limiting apparent magnitude or between the GALEX bands. This estimate is close to that found from samples of blue galaxies in the local universe selected in the visible, and similar to that derived at z ~ 3 for LBGs with similar rest frame selection criteria. This result supports models that predict anti-biasing of star forming galaxies at low redshift, and brings an additional clue to the downsizing of star formation at z<1.

description: The pace of evolution of physical systems is fundamentally constrained by quantum speed limits (QSL), which have found broad applications in quantum science and technology. We consider the speed of evolution for quantum systems undergoing stochastic dynamics due to continuous measurements. It is shown that that there are trajectories for which standard QSL are violated, and we provide estimates for the range of velocities in an ensemble of realizations of continuous measurement records. We determine the dispersion of the speed of evolution and characterize the full statistics of single trajectories. By characterizing the dispersion of the Bures angle, we further show that continuous quantum measurements induce Brownian dynamics in Hilbert space.

description: English Summary
Research software is commonly used in various disciplines to perform research and as a research object itself. Therefore, it is covered by multiple NFDI consortia. To fulfill the FAIR criteria for research software, it needs to be described with meaningful and interoperable metadata enhancing transparency, reproducibility, and reusability in research. While there exist some metadata schemes for research software, e.g., CodeMeta, they have some limitations, e.g., missing elements and missing semantic interoperability.
To address these issues, this working group aims to provide a comprehensive metadata vocabulary for research software, compatible with existing frameworks such as schema.org and CodeMeta. Also, the working group will support all NFDI consortia in applying the vocabulary as well as develop domain-specific extensions if needed.
 
German Summary
Forschungssoftware wird in vielen Bereichen der Wissenschaft häufig zur Forschung genutzt und stellt teilweise selbst ein Forschungsobjekt dar. Viele NFDI Konsortien decken Forschungssoftware als wichtiges Forschungsartefakt mit ab und wollen das Forschungssoftware in Zukunft die FAIR-Kriterien erfüllt, um die Transparenz, Reproduzierbarkeit und Wiederverwendbarkeit in software-basierter Forschung zu erhöhen. Damit Forschungssoftware die FAIR-Kriterien erfüllt, muss sie mit aussagekräftigen und interoperablen Metadaten beschrieben werden. Dafür werden entsprechende Metadatenschemata benötigt. Es gibt zwar einige Metadatenschemata für Forschungssoftware, z. B. CodeMeta, aber sie weisen einige Einschränkungen auf, z. B. fehlende Elemente und fehlende semantische Interoperabilität. Um diese Probleme zu beheben, hat sich diese Arbeitsgruppe zum Ziel gesetzt, ein umfassendes Metadatenvokabular für Forschungssoftware bereitzustellen, das mit bestehenden Standards wie schema.org und CodeMeta kompatibel ist. Damit wird die Arbeitsgruppe alle NFDI-Konsortien bei der Anwendung und Etablierung von Metadatenschemeta für Forschungssoftware unterstützen, z.B. bei Entwicklung von bereichsspezifischen Erweiterungen.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Zusammenfassung Im Jahr 1820 traten zwei Universitätsabsolventen, Christian Gottfried Ehrenberg und Wilhelm Hemprich, eine Forschungsreise nach Nordafrika an, die eine der ersten vom preußischen Staat maßgeblich getragenen Reiseunternehmungen darstellt. Wesentliches Ziel der Reise war das Sammeln von naturkundlichen Exemplaren für die junge Berliner Museumslandschaft. Der Beitrag ordnet die afrikanische Forschungsreise in die wissenschaftliche Laufbahn Ehrenbergs ein, der als einziger Reisender überlebte, sowie in die Geschichte der Berliner Wissenschaftslandschaft im frühen 19. Jahrhundert. Dabei konzentriert sich der Beitrag auf die Medien – insbesondere Sammlungsverzeichnisse und Sammlungsobjekte – die die Reisenden im Feld einsetzen mussten, um ihre Identität als gelehrte Naturforscher gegenüber ihren Förderern zu inszenieren und damit ihre Position in der preußischen Wissenschaft strategisch zu sichern. Abstract In 1820, two university graduates, Christian Gottfried Ehrenberg and Wilhelm Hemprich, embarked on a research expedition to North Africa, one of the first travel ventures funded by the Prussian state. The main goal of the trip was to collect natural history specimens for the Berlin museums. The article contextualizes the research voyage within the scientific career of Ehrenberg, the only surviving member of the voyage, and in the history of Berlin's scientific landscape in the early 19th century. The article focuses on the media – particularly collection inventories and collection objects – that the travelers implemented in the field to fashion their identity as learned naturalists and thus strategically secure their position in Prussian science. Résumé En 1820, deux diplômés de lʼuniversité, Christian Gottfried Ehrenberg et Wilhelm Hemprich, se sont lancés dans une expédition de recherche en Afrique du Nord, lʼune des premières expéditions de voyage à bénéficier dʼun soutien important de lʼÉtat prussien. Le but principal du voyage était de collecter des spécimens d'histoire naturelle pour le jeune paysage muséal de Berlin. Le présent article se propose de situer le voyage de recherche en Afrique dans la carrière scientifique dʼEhrenberg, le seul voyageur survivant, ainsi que dans lʼhistoire de lʼinfrastructure scientifique de Berlin au début du XIXe siècle. Dans ce but, lʼarticle se concentre sur les médias – en particulier les inventaires et les objets de collection – que les voyageurs ont dû utiliser sur le terrain pour mettre en scène leur identité de naturalistes cultivés vis-à-vis de leurs mécènes afin d’assurer stratégiquement leur position dans la science prussienne.

description: Bhabha scattering is one of the processes at the ILC where high precision data will be expected. The complete NNLO corrections include radiative loop corrections, with contributions from Feynman diagrams with five external legs. We take these diagrams as an example and discuss several features of the evaluation of pentagon diagrams. The tensor functions are usually reduced to simpler scalar functions. Here we study, as an alternative, the application of Mellin-Barnes representations to 5-point functions. There is no evidence for an improved numerical evaluation of their finite, physical parts. However, the approach gives interesting insights into the treatment of the IR-singularities.
