description: Relativistic jets launched by Active Galactic Nuclei are among the most powerful particle accelerators in the Universe. The emission over the entire electromagnetic spectrum of these relativistic jets can be extremely variable with scales of variability from less than few minutes up to several years. These variability patterns, which can be very complex, contain information about the acceleration processes of the particles and the area(s) of emission. Thanks to its sensitivity, five-to twenty-times better than the current generation of Imaging Atmospheric Cherenkov Telescopes depending on energy, the Cherenkov Telescope Array will be able to follow the emission from these objects with a very accurate time sampling and over a wide spectral coverage from 20 GeV to > 20 TeV and thus reveal the nature of the acceleration processes at work in these objects. We will show the first results of our lightcurve simulations and long-term behavior of AGN as will be observed by CTA, based on state-of-art particle acceleration models.

description: We adopt Convolutional Neural Networks (CNNs) to be our parametric model to learn discriminative features and classifiers for local patch classification. Based on the occurrence frequency distribution of classes, an ensemble of CNNs (CNN-Ensemble) are learned, in which each CNN component focuses on learning different and complementary visual patterns. The local beliefs of pixels are output by CNN-Ensemble. Considering that visually similar pixels are indistinguishable under local context, we leverage the global scene semantics to alleviate the local ambiguity. The global scene constraint is mathematically achieved by adding a global energy term to the labeling energy function, and it is practically estimated in a non-parametric framework. A large margin based CNN metric learning method is also proposed for better global belief estimation. In the end, the integration of local and global beliefs gives rise to the class likelihood of pixels, based on which maximum marginal inference is performed to generate the label prediction maps. Even without any post-processing, we achieve state-of-the-art results on the challenging SiftFlow and Barcelona benchmarks.

Priesterkönig, Teufelsanbeter und Synkretismus in Indien?
Creators: name: Flüchter, Antje
Publisher: name: Leipziger Universitätsverlag
Year: 2008

description: Which options to construct sacral kingship were thinkable in the Early Modern period under conditions of different religions? The legendary (Christian) king John possessed sacral and profane power, ruling over religiously heterogeneous subjects. The (‘Hinduistic’) Samudrin of Calicut legitimized and anchored his rulership ritually in a cult perceived as devil worship. The Mughal Jalaluddin Muhammad Akbar combined elements of many different Indian religions in a new form of belief, stabilizing his rule by an appeal to the loyalty also of his non-Muslim subjects. European observers had difficulties to understand these policies of religious integration, Jesuit knowledge was only rarely received. Akbar’s tolerant approach did not fit into European concepts of confessional polarization, nor did his spiritually anchored tolerance fit into secular concepts of the Enlightenment period.

description: Deliverable D9.2 describes the REINFORCE evaluation instruments and provides a user guide for the demonstrators to assist in the practical handling of data collection procedures, including compliance with ethical guidelines. It summarises the underlying evaluative framework, as described in more detail in D9.1, which leads to the description of the evaluative instruments, namely the event monitoring sheet, the feedback survey for events, the access to Zooniverse data, the Zooniverse experience survey, the pre and post questionnaire for citizen scientists and the self-assessment of demonstrator teams for measuring perceived impact. Furthermore, the deliverable describes the limitations of self-assessment questionnaires and how some of the associated flaws can be avoided.

description: We study a locally resonant granular material in the form of a precompressed Hertzian chain with linear internal resonators. Using an asymptotic reduction, we derive an effective nonlinear Schrödinger (NLS) modulation equation. This, in turn, leads us to provide analytical evidence, subsequently corroborated numerically, for the existence of two distinct types of discrete breathers related to acoustic or optical modes: (a) traveling bright breathers with a strain profile exponentially vanishing at infinity and (b) stationary and traveling dark breathers, exponentially localized, time-periodic states mounted on top of a non-vanishing background. The stability and bifurcation structure of numerically computed exact stationary dark breathers is also examined. Stationary bright breathers cannot be identified using the NLS equation, which is defocusing at the upper edges of the phonon bands and becomes linear at the lower edge of the optical band.

Der Doge vor dem Altar –
Creators: name: Schilling, Ruth
Publisher: name: Leipziger Universitätsverlag
Year: 2008

description: The visual representation of rulers kneeling in front of an altar can reveal how and to which extent the combination of religion and politics is part of each individual political culture. In Venice, a special type of representing the doge participating in a religious service was generated in the second half of the 16th century. At first one might argue that this demonstrates how the combination of religious and political rights was visualized by using specifically post-tridentine catholic symbols. However, a detailed analysis shows the priority of the ducal dignity over confessional symbols.

Das Angesicht des Herrschers.
Creators: name: Schwedler, Gerald
Publisher: name: Leipziger Universitätsverlag
Year: 2008

description: Different strategies of visual representation of rulers can be observed on the basis of a close analysis of images on coins produced in the early middle ages. The propagandistic use of ruler images is related to theological debates on the feasibility and appropriateness of visual representations, e. g. the Byzantine iconoclastic controversy or the Islamic ban on figurative images. The transcultural comparison of visual representations is based on sources from Byzantium, the Latin West and the Islamic caliphate of the Umayyads and Abbasids in the 7th and 8th centuries.

description: Christian defeats in the Near East since the middle of the 12th century were interpreted by Western and Oriental clerics in a similar way: they put the blame on Christian sins. On the other hand, we can see differences in the prediction of prospective events, making a clear-cut distinction of Latin and Oriental Christians impossible. While Armenians and Latins hoped for a speedy victory of purified Christianity over the Muslims, Syriac Orthodox Christians directed their hope of retaliation to an eschatological future. The reasons for these differences are due to the social and political environments of the respective Christian communities.

Der Herrscher als Pilger im westlichen und östlichen Mittelalter –
Creators: name: Kolditz, Sebastian
Publisher: name: Leipziger Universitätsverlag
Year: 2008

description: Investigating medieval royal pilgrimage from a comparative perspective, certain characteristics can be observed: Byzantine emperors normally did not go on pilgrimage, preferring to collect holy relics in their capital. In the West, royal pilgrimage flourished especially during the Later Middle Ages, playing a key role in the practice of rulership, without, however, making a significant contribution to the sacral character of monarchy. Christian kings seldom crossed the borders of their realms to visit sacred places. Muslim rulers (apart from the early caliphs) followed a similar pattern, often avoiding to perform the hajj to Mecca personally. Instead, royal pilgrimage over long distances was a significant phenomenon at the periphery of both religious spheres: in West Africa and Scandinavia.

description: Laser cooling is a fundamental technique used in primary atomic frequency standards, quantum computers, quantum condensed matter physics and tests of fundamental physics, among other areas. It has been known since the early 1990s that laser cooling can, in principle, be improved by using squeezed light as an electromagnetic reservoir; while quantum feedback control using a squeezed light probe is also predicted to allow improved cooling. Here, we implement quantum feedback control of a micro-mechanical oscillator for the first time with a squeezed probe field. This allows quantum-enhanced feedback cooling with a measurement rate greater than it is possible with classical light, and a consequent reduction in the final oscillator temperature. Our results have significance for future applications in areas ranging from quantum information networks, to quantum-enhanced force and displacement measurements and fundamental tests of macroscopic quantum mechanics.

description: At nearly the same time the ruling dynasties changed both in the Frankish realm and in the Islamic caliphate around the middle of the 8th century. A detailed analysis of the religious and cultural conditions shows that rulers had to take into account the respective stages of institutionalization and canonization processes. A close comparative look at the political options open to historical contemporaries in different “cultures” or “civilizations” can make a substantial contribution towards conceptualizing transcultural historiography in global perspective.

Year: 2023

description:
In the present thesis, I argue that Karen Ngs attempt to draw on resources from Hegels Science of Logic to defend a naturalist interpretation of the Hegelian account of cognition is not as promising as she thinks it is. In the first section, I offer an overview of the debate between anti-naturalist and naturalist interpretations of the Hegelian logical space of reasons. I clarify some terms involved in the debate and locate Ngs novel interpretation in a wider philosophical discussion. In the second section, I offer some arguments to resist Ngs interpretation, according to which the Idea of Life is never overcome in later stages of the Science of Logic. I uncover Ngs interpretive presuppositions and put pressure on her interpretation. Finally, I consider two potential objections to my arguments and sketch a different line of thought to approach Hegels Idea of Life.

description: BaMnF$_4$ microsheets have been prepared by hydrothermal method. Strong room-temperature blue-violet photoluminescence has been observed (absolute luminescence quantum yield 67%), with two peaks located at 385 nm and 410 nm, respectively. More interestingly, photon self-absorption phenomenon has been observed, leading to unusual abrupt drop of luminescence intensity at wavelength of 400 nm. To understand the underlying mechanism of such emitting, the electronic structure of BaMnF$_4$ has been studied by first principles calculations. The observed two peaks are attributed to electrons' transitions between the upper-Hubbard bands of Mn's $t_{2g}$ orbitals and the lower-Hubbard bands of Mn's $e_g$ orbitals. Those Mott gap mediated d-d orbital transitions may provide additional degrees of freedom to tune the photon generation and absorption in ferroelectrics.

description: In the 4th century, both in the Roman and in the Sasanian empire religion and politics were combined in new ways. Christianity gradually rose to the position of the official religion in Rome, while Zoroastrianism was institutionalized as an official cult in Persia. Institutional changes introduced by the Sasanians can be interpreted partly as a reaction to Roman models and policies, and changing attitudes of the Sasanian emperors to their Christian subjects, as well as to Jews and Manichaeans, should be seen as a reflection of shifting Roman policies towards „orthodox“ and „heretical“ Christians.

description: Corona-Australis is one of the nearest regions to the Sun with active star formation, but despite the close proximity (d~150 pc) our current picture of this starburst is not yet complete. Our team has recently revised the census of Corona-Australis stars using Gaia- DR2 data and discovered a distributed population of young stars located in the Galactic north of the dark clouds that is twice as numerous as the historically known stellar population concentrated around the densest cores of the region. Here, we build on the current census of stars in this region by combining the Gaia-EDR3 catalogue with astrometric and photometric ground-based data delivered by the Cosmic-DANCe project. We use our new sample of members and high-resolution spectroscopy to revisit the structure and kinematics of the Corona-Australis star-forming region.

description: All-organic-based photovoltaic solar cells have attracted considerable attention because of their low-cost processing and short energy payback time. In such systems the primary dissociation of an optical excitation into a pair of photocarriers has been recently shown to be extremely rapid and efficient, but the physical reason for this remains unclear. Here, two-dimensional photocurrent excitation spectroscopy, a novel non-linear optical spectroscopy, is used to probe the ultrafast coherent decay of photoexcitations into charge-producing states in a polymer:fullerene based solar cell. The two-dimensional photocurrent spectra are interpreted by introducing a theoretical model for the description of the coupling of the electronic states of the system to an external environment and to the applied laser fields. The experimental data show no cross-peaks in the two-dimensional photocurrent spectra, as predicted by the model for coherence times between the exciton and the photocurrent producing states of 20\,fs or less.

Year: 2008

description: In the last few years, the term transcultural has been increasingly used in historiography. Since „culture“ can be understood in very different ways it is not self-evident which concept of culture transcultural refers to. With regard to currently prevailing usage and referring to the debate on transnational history, transcultural history is defined as an approach that considers the paradigm of civilisations explicitly to be a construct of the 9th century. Transcultural, therefore, is not meant to be a trendy substitute for intercultural. A transcultural approach rather aims to problematize “civilisation” as a unit of history.

Befragte wurden gebeten, die drei wichtigsten politischen Ereignisse der letzten 100 Jahre und seit 2000, sowie das früheste politische Ereignis, an das sie sich erinnern können, zu nennen. Die Ergebnisse zeigen, dass einige wenige historische Ereignisse von vielen Teilnehmenden aus aller Welt als wichtig erachtet werden. Dieser Übereinstimmung sind allerdings Grenzen gesetzt: die Erinnerung an verschiedene Weltregionen folgt einem Muster von Zentrum / Peripherie. Zudem gibt es deutliche Unterschiede hinsichtlich der Disposition ausländischer Ereignisse zu benennen.

description: Structural and Cultural Foundations of the Political Sphere in East Central Europe in the 20th Century The cultural turn in political history challenges established notions of East Central Europe. Yet, a survey of recent studies shows that the concept of East Central Europe is still provides valid insights into specific traits of the regions within a European context. The article explores the national connotations of statehood since the late nineteenth century. It argues that not so much unsolved minority problems, but rather the need to develop coherent ideas of a national state and a national territory within the majority populations posed the most serious problems in establishing the new political order after 1918. The answer was to link national statehood to farreaching reform projects. The communist regimes took a similar approach in propagating socialist utopia within a national framework. Even today, discourses of national statehood, liberty and civil society reflect specific traditions of the historical experience of East Central Europe.

description: The homogeneously catalyzed reductive amination of the long-chain aldehyde undecanal with diethylamine was performed in an aqueous microemulsion system using the non-ionic surfactant Marlophen NP8. The experiments showed that the used water-soluble rhodium/SulfoXantphos catalyst system is suitable for this reaction. The Rh-catalyzed formation of the alcohol by-product can be completely suppressed by the use of carbon monoxide with its stabilizing effect of the catalyst system. In addition to pressure and temperature, the most important parameters for the reaction performance of the reductive amination are the concentrations of reactants. Especially, the initial concentration of the aldehyde has a strong impact on the chemoselectivity, and the formation of aldol by-product due to the fact that both, the enamine condensation and the aldol condensation are equilibrium reactions.

description: The true muonium $(μ\barμ)$ bound state presents an interesting test of light-cone quantization techniques. In addition to exhibiting the standard problems of handling non-perturbative calculations, true muonium requires correct treatment of $e\bar{e}$ Fock-state contributions. Having previously produced a crude model of true muonium using the method of iterated resolvents, our current work has focused on the inclusion of the box diagrams to improve the cutoff-dependent issues of the model. Further, a parallel computer code, TMSWIFT, allowing for smaller numerical uncertainties, has been developed. This work focuses on the current state of these efforts to develop a model of true muonium that is testable at near-term experiments.

Sozialistische Stadt“ versus „europäische Stadt“ –

Publisher: name: Leipziger Universitätsverlag
Year: 2008

description: The „Socialist city“ versus the „European city“ – urbanization and ruralization in Eastern Europe In most parts of Eastern Europe the transition from agrarian to industrial societies took place only after World War II. The process of urbanization was influenced by the socialist planning economy. Under this condition, the concept of the “socialist city” found its realization in the modern reconstruction of old historical towns and the foundation of new industrial towns. Today the image of Eastern European capitals consists of monumental centers and monotonous neighborhoods. The development, however, leading to this dichotomy was the result of a lot of contradictions. On the one side, there was a lack of civil society already before the communist seize of power. On the other side, the exodus from the countryside during the period of socialist industrialization lead to a ruralization of already existing cities. At the end the “socialist city” was able to supply its inhabitants with a minimum of dwelling. But it still required the renunciation of urbanity and autonomy.

description: We present a detailed study of the static spherically symmetric solutions in de Rham-Gabadadze-Tolley (dRGT) theory. Since the diffeomorphism invariance can be restored by introducing the Stückelberg fields $ϕ^a$, there is new invariant $I^{ab}=g^{μν}\partial_μϕ^a\partial_νϕ^b$ in the massive gravity, which adds to the ones usually encountered in general relativity (GR). In the unitary gauge $ϕ^a=x^μδ_μ^a$, any inverse metric $g^{μν}$ that has divergence including the coordinate singularity in GR would exhibit a singularity in the invariant $I^{ab}$. Therefore, there is no conventional Schwarzschild metric if we choose unitary gauge. In this paper, we obtain a self-consistent static spherically symmetric ansatz in the nonunitary gauge. Under this ansatz, we find that there are seven solutions including the Schwarzschild solution, Reissner-Nordström solution and five other solutions. These solutions may possess an event horizon depending upon the physical parameters (Schwarzschild radius $r_s$, scalar charge $S$ and/or electric charge $Q$). If these solutions possess an event horizon, we show that the singularity of $I^{ab}$ is absent at the horizon. Therefore, these solutions may become candidates for black holes in dRGT.

description: We use simulated galaxy surveys to study: i) how galaxy membership in redMaPPer clusters maps to the underlying halo population, and ii) the accuracy of a mean dynamical cluster mass, $M_σ(λ)$, derived from stacked pairwise spectroscopy of clusters with richness $λ$. Using $\sim\! 130,000$ galaxy pairs patterned after the SDSS redMaPPer cluster sample study of Rozo et al. (2015 RMIV), we show that the pairwise velocity PDF of central--satellite pairs with $m_i < 19$ in the simulation matches the form seen in RMIV. Through joint membership matching, we deconstruct the main Gaussian velocity component into its halo contributions, finding that the top-ranked halo contributes $\sim 60\%$ of the stacked signal. The halo mass scale inferred by applying the virial scaling of Evrard et al. (2008) to the velocity normalization matches, to within a few percent, the log-mean halo mass derived through galaxy membership matching. We apply this approach, along with mis-centering and galaxy velocity bias corrections, to estimate the log-mean matched halo mass at $z=0.2$ of SDSS redMaPPer clusters. Employing the velocity bias constraints of Guo et al. (2015), we find $\langle \ln(M_{200c})|λ\rangle = \ln(M_{30}) + α_m \ln(λ/30)$ with $M_{30} = 1.56 \pm 0.35 \times 10^{14} M_\odot$ and $α_m = 1.31 \pm 0.06_{stat} \pm 0.13_{sys}$. Systematic uncertainty in the velocity bias of satellite galaxies overwhelmingly dominates the error budget.

description: The hydroaminomethylation of the long-chain olefin 1-decene and diethylamine with a homogeneous Rh(acac)(cod)/SulfoXantphos catalyst complex as a one-pot synthesis was investigated. The influence of reaction conditions such as temperature and synthesis gas pressure was determined, as well as the effects of the initial concentrations of catalyst precursor, ligand, and reactants on the yield of fatty amine. Hydroaminomethylation was successfully carried out in an aqueous microemulsion system using a non-ionic surfactant with a reaction time of 2 h. A maximum yield of 34%, high regioselectivities >97%, and chemoselectivities >85% were achieved.

description: The relationship between city and country in 19th and 20th century Europe – a brief sketch While authors like Marx attached prime importance to the relationship between the city and the country many sociologists today deny that there are any meaningful distinctions left between them. The article tries to sketch the most important changes and the most important regional variations within Europe over the last two hundred years and in doing so gives special prominence to structural changes within the economy and society. Without wanting to diminish the importance of processes of industrialization for the dissolution of earlier dividing lines between the (walled) city and its surroundings the articles proposes to make use of recent work on the economics of agglomeration because such an approach has at least two advantages: It allows to identify more clearly the exceptional character of industrial towns in coal regions and to conceptualize more convincingly the conditions of growth of the many other types of cities growing rapidly in the late 19th and 20th century. This is especially true for the cities of Southern Europe where the long and widespread absence of industrialization did not prevent urban growth. Well into the 21st century the relationship between the city and the country in these regions nevertheless shows quite different features than the metropolitan regions in the northwestern parts of the continent. (The exclusion of Eastern Europe is solely due to the fact that another contribution to this volume deals with it.)

description: We investigate the parity of transmission spectra in a photonic crystal (PhC) waveguide with a side-coupled cavity and a partially blocking element. We demonstrate, by means of numerical calculations, that by varying the cavity-block distance the spectra vary from being asymmetric with blue parity, to being symmetric (Lorentzian), to being asymmetric with red parity. For cavity-block distances larger than five PhC lattice constants, we show that the transmission spectrum is accurately described as the transmission spectrum of a Fabry-Perot etalon with a single propagating Bloch mode, and that the parity of the transmission spectrum correlates with the Fabry-Perot roundtrip phase.

description: Research on Empires in the historiography on Eastern Europe Since the 1990s, research in East European History has been deeply influenced by the concept of empire and reinvigorated by the growing interest in the complexities of the multinational and multi-confessional character of the area. It is the goal of this contribution not only to showcase the recent scholarship on the Habsburg Monarchy, the Russian Autocracy and the Soviet Union as empires, but also to address the most interesting questions that are currently pushing the field in new directions. All three cases reveal that neither the difference between maritime and continental empires, often overemphasized in earlier scholarship, nor the distinction between seemingly “modern” (Western) and “backward” (Eastern) empires can be sustained. The peculiarities of all three empires highlight rather the central question of to what extent these cases were empires at all, and of the development of the relationship between the national and imperial traits of the various states.

description: We study the three-dimensional antiferromagnetic Ising model in both uniform longitudinal ($H$) and transverse ($Ω$) magnetic fields by using the effective-field theory with finite cluster $N=1$ spin (EFT-1). We analyzed the behavior of the magnetic susceptibility to investigate the reentrant phenomena we have seen the same phase diagram previously obtained in another papers. Our results shows the presence of two divergences in the susceptibility that indicates the existence of a reentrant behaviour.

title: Implementation of Low-Cost and Open-Source Instrumentation in 2D Material Research
Creators: name: Maraba, Diren
Publisher: name: Georgia State University
Year: 2023

description:
This dissertation examines the importance of open-sourced scientific instrumentation in two-dimensional (2D) material research. 2D materials are gaining attention due to their extraordinary electrical, mechanical, optical, and thermal properties and their potential to transform various fields. However, studying these materials often requires complex and expensive scientific instrumentation, which can limit the accessibility and progress of research. The study explores the potential of open-source software and hardware in scientific instrumentation, and its role in democratizing access, fostering collaboration, and accelerating innovation.


The study presents two instruments implemented for 2D material research, using only open-source software and hardware, and demonstrates experiments conducted with these instruments. Additionally, the study explores broader implications of open-sourced scientific instrumentation by demonstrating a motorized variable filter stage and retractable leadless pacemaker. The dissertation concludes by emphasizing the critical role of open-source instruments in the advancement of material science and the broader scientific community and the need for ongoing support and engagement to fully realize their potential.
A computational approach to Milnor fiber cohomology

description: In this note we consider the Milnor fiber $F$ associated to a reduced projective plane curve $C$. A computational approach for the determination of the characteristic polynomial of the monodromy action on the first cohomology group of $F$, also known as the Alexander polynomial of the curve $C$, is presented. This leads to an effective algorithm to detect all the monodromy eigenvalues and, in many cases, explicit bases for the monodromy eigenspaces in terms of polynomial differential forms.

Subversion am Rande.

description: This article compares three historical periods of crossing German borders and the corresponding types of migration: illegal migration from Poland to Germany between 1890 and 1933, escape aid from Germany and the occupied territories during National Socialism, and human smuggling and migration aid to Germany between 1989 and 2004. Through these comparisons, continuities of migration and policy patterns can be discovered. Borders and cross-border migration are both symbolic and practically relevant for the production of social homogeneity. The possibility of successfully crossing the border depends to a high degree on the attitudes of the local population towards migrants. During German history these attitudes have been shifting from indifference to hostility, which results in hardening the borders.

description: Despite the keen interest the social sciences have shown in migration as a form of border transgression, the figure of the stowaway has received surprisingly little critical scrutiny. This paper suggests that the policing of stowaways by sea merits greater attention. Following a brief discussion of the changing problematic of the stowaway, it focuses on one particular aspect of the governance of stowaways: the role of maritime insurance companies and shipping consultants who have made the prevention and resolution of stowaway incidents into a normal part of their business. A focus on the activities of these agents is merited because it allows for a fuller account of the policing of transgressive migratory practices and identities at maritime borders. But this focus also allows for a rethinking of certain key concepts within migration and border studies more broadly. First, it prompts us to revise what we understand by ‘securitization’. To this end the paper highlights the extent to which the securitization of the stowaway involves banal and technical practices much more it does than the dramatic acts of threat construction usually associated with the term. Second, this case challenges us to rethink how we understand deportation. For it brings to light the way in which insurers and shipping experts operate as a private industry which specializes in the disembarkation and repatriation of stowaways. A fascinating feature of this stowaway removal industry is that it must negotiate the return of its subjects not just into the political space of the world of states, but the terrestrial space of dry land.
