description: We propose a regularization procedure for the novel Einstein-Gauss-Bonnet theory of gravity, which produces a set of field equations that can be written in closed form in four dimensions. Our method consists of introducing a counter term into the action, and does not rely on the embedding or compactification of any higher-dimensional spaces. This counterterm is sufficient to cancel the divergence in the action that would otherwise occur, and exactly reproduces the trace of the field equations of the original formulation of the theory. All other field equations display an extra scalar gravitational degree of freedom in the gravitational sector, in keeping with the requirements of Lovelock's theorem. We discuss issues concerning the equivalence between our new regularized theory and the original.

description: Abstract: The text of Gudea Cylinder A provides evidence for many different repetition phenomena. The composition, written in Sumerian and dating to the end of the second millennium BCE, celebrates the building of the Eninnu temple by the ruler Gudea and is a sophisticated literary work. My aim is to investigate the role played by some forms of repetition as structuring devices in this complex hymn. To achieve this, I select and discuss some examples of ring compositions, structural formulas, textual parallelism, and narrative repetition within the text. Such phenomena and their significance in the creation of meaning in cuneiform texts are currently the focus of REPAC’s research. This study is only meant to offer an example of REPAC’s approach to the analysis of an ancient Mesopotamian literary composition such as Gudea Cylinder A.

description: Organizations that provide consulting services relating to the performance and activity in the financial markets lead to a corresponding positive chain reaction. Namely, the domestic and foreign companies wishing to invest in providing information regarding the selection of investments, as well as information about the performance of companies in which it invests. Such business information leads to a reduction in risk, which is immanent to the business activity, especially one that is realized through the financial markets. The risk increases with uncertainty, respectively, when there is poor access to the necessary business informations. Reducing the risk increases the attractiveness of the investment, which is a stimulant for domestic and foreign investors to evaluate various combinations of risk / return. Increasing levels of investment in local companies develop the capital market as an integral part of the domestic financial market, with the inflow of funds realized through investments in new businesses, the recapitalization of existing companies, the consolidation of the financial system.

description: We have synthesized unique colloidal nanoplatelets of the ferromagnetic two-dimensional (2D) van der Waals material CrI3 and have characterized these nanoplatelets structurally, magnetically, and by magnetic circular dichroism spectroscopy. The isolated CrI3 nanoplatelets have lateral dimensions of ~25 nm and ensemble thicknesses of only ~4 nm, corresponding to just a few CrI3 monolayers. Magnetic and magneto-optical measurements demonstrate robust 2D ferromagnetic ordering in these nanoplatelets with Curie temperatures similar to those observed in bulk CrI3, despite the strong spatial confinement. These data also show magnetization steps akin to those observed in micron-sized few-layer 2D sheets and associated with concerted spin-reversal of individual CrI3 layers within few-layer van der Waals stacks. Similar data have also been obtained for CrBr3 and anion-alloyed Cr(I1-xBrx)3 nanoplatelets. These results represent the first example of laterally confined 2D van der Waals ferromagnets of any composition. The demonstration of robust ferromagnetism at nanometer lateral dimensions opens new doors for miniaturization in spintronics devices based on van der Waals ferromagnets.

description: We investigate the long-range phase coherence of homogeneous and trapped Bose gases as a function of the geometry of the trap, the temperature, and the mean-field interactions in the weakly interacting limit. We explicitly take into account the (quasi)condensate depletion due to quantum and thermal fluctuations, i.e., we include the effects of both phase and density fluctuations. In particular, we determine the phase diagram of the gas by calculating the off-diagonal one-particle density matrix and discuss the various crossovers that occur in this phase diagram and the feasibility of their experimental observation in trapped Bose gases.

 COMMENTS. Most of the material upon which the description was based was fieldcollected in Florida, where it is evidently very common. In Belize, it is represented by a small number of specimens taken from avocado. The minute differences used to differentiate T. confusa from T. perseae (which was described by Nakahara in the same 1995 paper, and see p. 7 here) may prove to be intraspecific variation, especially when the occurrence of both nominal species on avocado is taken into account.

description: The nation state is a central component of social and political processes in the modern world. As a legitimizing ideology of the nation state, nationalism constructs a self-understanding of cultural and state homogeneity as well as parameters of inclusion and exclusion that are presented as primordial or perennial. The understanding of the nation and nationality as a social construction raises the question of the reasons for the emergence, diffusion, and mechanisms of nationalism. Starting in the 1960s, research on nationalism was shaped by theoretical approaches that located the genesis of nationalism in modernity. This bachelor thesis discusses three theories of this modernist paradigm. The ideological approach of Elie Kedourie, the socio-cultural approach of Ernest Gellner and the socio-economic approach of Tom Nairn offer different explanatory models of the genesis of nationalism and differ in their meta-theoretical and methodological premises, historical-empirical interpretations and normative evaluations of nationalism. First, this work presents the theoretical foundations and direct references of the approaches and compares their arguments. Building on this, these theories are applied using the case study of Japanese nationalism from the Meiji period onwards. Written in German. Der Nationalstaat ist zentraler Bestandteil sozialer und politischer Prozesse in der modernen Welt. Als legitimierende Ideologie des Nationalstaates konstruiert der Nationalismus ein Selbstverständnis kultureller und staatlicher Homogenität und Parameter der In- und Exklusion, die als primordial oder perennial dargestellt werden. Das Verständnis der Nation und Nationalität als soziale Konstruktion bedingt die Frage nach den Entstehungsgründen, der Diffusion und den Mechanismen des Nationalismus. Die Nationalismusforschung wurde ab den 1960er Jahren von theoretischen Ansätzen geprägt, die die Genese des Nationalismus in der Moderne verorteten. Diese Abschlussarbeit diskutiert drei Theorien dieses modernistischen Paradigmas. Der ideologische Ansatz von Elie Kedourie, der soziokulturelle Ansatz von Ernest Gellner und der sozioökonomische Ansatz von Tom Nairn bieten unterschiedliche Erklärungsmodelle der nationalistischen Genese und unterscheiden sich in ihren metatheoretischen und methodologischen Prämissen, historisch-empirischen Interpretationen und normativen Bewertungen des Nationalismus. Zunächst stellt diese Arbeit die theoretischen Grundlagen und direkten Bezüge der Ansätze dar und vergleicht ihre Argumentationen. Darauf aufbauend werden die Theorien anhand des Fallbeispiels des japanischen Nationalismus ab der Meiji-Periode zur Anwendung gebracht.

description: This paper synthesizes the academic and professional literature about participation in the Women, Infants and Children (WIC) Program in the United States. First, we compile evidence about differences in enrollment, perceptions, and experiences by eligible populations (women, infants, children) and by social categories (e.g., race, educational attainment, immigration status). Second, we describe barriers to participation through a twofold typology: operational and systemic. Operational barriers concern the perceived hassle of several aspects of WIC, and systemic barriers involve issues of stigma, fear, access, and language.

description: We present simulations of galaxy formation, based on the GADGET-3 code, in which a sub-resolution model for star formation and stellar feedback is interfaced with a new model for AGN feedback. Our sub-resolution model describes a multiphase ISM, accounting for hot and cold gas within the same resolution element: we exploit this feature to investigate the impact of coupling AGN feedback energy to the different phases of the ISM over cosmic time. Our fiducial model considers that AGN feedback energy coupling is driven by the covering factors of the hot and cold phases. We perform a suite of cosmological hydrodynamical simulations of disc galaxies ($M_{\rm halo, \, DM} \simeq 2 \cdot 10^{12}$ M$_{\odot}$, at $z=0$), to investigate: $(i)$ the effect of different ways of coupling AGN feedback energy to the multiphase ISM; $(ii)$ the impact of different prescriptions for gas accretion (i.e. only cold gas, both cold and hot gas, with the additional possibility of limiting gas accretion from cold gas with high angular momentum); $(iii)$ how different models of gas accretion and coupling of AGN feedback energy affect the coevolution of supermassive BHs and their host galaxy. We find that at least a share of the AGN feedback energy has to couple with the diffuse gas, in order to avoid an excessive growth of the BH mass. When the BH only accretes cold gas, it experiences a growth that is faster than in the case in which both cold and hot gas are accreted. If the accretion of cold gas with high angular momentum is reduced, the BH mass growth is delayed, the BH mass at $z=0$ is reduced by up to an order of magnitude, and the BH is prevented from accreting below $z \lesssim 2$, when the galaxy disc forms.

description: In order to perform Bayesian parameter estimation to infer the source properties of gravitational waves from compact binary coalescences (CBCs), the noise characteristics of the detector must be understood. It is typically assumed that the detector noise is stationary and Gaussian, characterized by a power spectral density (PSD) that is measured with infinite precision. We present a new method to incorporate the uncertainty in the power spectral density estimation into the Bayesian inference of the binary source parameters and apply it to the first 11 CBC detections reported by the LIGO- Virgo Collaboration. We find that incorporating the PSD uncertainty only leads to variations in the positions and widths of the binary parameter posteriors on the order of a few percent.

The aim of the workshop was to determine the objective of the FAIR Office Austria. The participants explored whom a FAIR Office Austria should serve, who the partners and the clients are, which services it should offer as well as what is in scope and what is out of scope in relation to the overall project. The workshop was designed to find a clear mission statement and help the participants develop a common understanding and expectations. The results will be the basis for a concrete action plan. The participants agreed that a FAIR Office Austria should serve predominantly as an information hub and a mediator between (international) organizations (e.g. GO FAIR3, EOSC4, RDA5) and local reference points located within the Austrian research institutions and other stakeholders. A FAIR Office Austria must furthermore be organized and run by several (research) institutions to reflect a truly transdisciplinary, trans-institutional and national dimension. The local FAIR reference points shall be installed at research-performing institutions. Other types of institutions will be encouraged to appoint local reference points as well.
description: Zusammenfassung: Dieser Report enthält die Ergebnisse eines Ein-Tages-Workshops, der mit Partnern des Projektes FAIR Data Austria1 und einer Vertreterin des Horizon 2020 Projekts EOSC-Pillar2 durchgeführt wurde. Ziel des Workshops war es, herauszufinden, wofür ein FAIR Office Austria stehen sollte. Die Teilnehmenden diskutierten über mögliche Partner und Kunden und über konkrete Services, die angeboten werden sollten. Ebenso wichtig war die Definition der Nicht-Ziele. Der Workshop sollte zur Findung eines klaren Mission-Statements dienen und den Teilnehmenden dazu verhelfen, ein gemeinsames Verständnis und Erwartungen zu entwickeln. Die Ergebnisse werden die Grundlage für einen konkreten Maßnahmenplan bilden. Ein klares Ergebnis war, dass ein FAIR Office Austria in erster Linie als Informationsdrehscheibe und Vermittler zwischen (internationalen) Organisationen (z.B. GO FAIR3, EOSC4, RDA5) und lokalen Referenzpunkten innerhalb der österreichischen Forschungseinrichtungen und anderen Stakeholdern dienen sollte. Ein FAIR Office Austria, so eine weitere Erkenntnis, muss von mehreren, unterschiedlichen (Forschungs-)Organisationen aufgebaut und betrieben werden, um eine wirklich transdisziplinäre, trans-institutionelle und nationale Dimension widerzuspiegeln. Lokale FAIR-Referenzpunkte sollen an Universitäten eingerichtet werden, aber nicht auf diese beschränkt sein. Weitere Forschungseinrichtungen werden ermutigt, ebenfalls lokale Referenzpunkte zu benennen.

description: Individual and environmental factors compose the multifactorial, timeless and multidimensional phenomenon of gambling. To comprehend this phenomenon as fully as possible, the overall examination of its manifestations, i.e. legal, state, scientific, individual, social and economic, is of particular interest. The already existing legal framework and the state mechanism are moving in parallel towards taming the phenomenon. However, in the context of investigating and understanding the attitude of both the law and state towards this issue, reasons of expediency mainly arise. Players are divided into social and pathological, with the latter facing serious psychosocial and financial problems. The ever-increasing volume of these problems and the difficulty with which the pathological player is confronted in resolving them, become the catalyst that leads said individuals to cross the line and resort to criminal acts. The question raised, is whether the partial criminalization of gambling patterns is an appropriate measure towards dealing with this phenomenon or whether the intervention of scientific community is necessary.

description: We show that a two-band model with ${\bf k}$-dependent superconducting gaps well describes the transmission and optical conductivity measured for MgB$_2$ thin films. It is also shown that the two-band anisotropic model consistently describes the specific-heat jump and thermodynamic critical magnetic field $H_c$. A single-gap anisotropic model is shown to be insufficient to understand consistently optical and thermodynamic behaviors. In our model, the pairing symmetry in each band has an anisotropic characteristic which is determined almost uniquely; the superconducting gap in the $σ$-band has anisotropy in the ab-plane and the gap in the $π$-band has a prolate form exhibiting anisotropy in the c-direction. The anisotropy in the $σ$-band produces rather small effects on the physical properties compared to the anisotropy in the $π$-band.

Fate of the Bose polaron at finite temperature

description: We consider an impurity immersed in a Bose-Einstein condensate with tunable boson-impurity interactions. Such a Bose polaron has recently been predicted to exhibit an intriguing energy spectrum at finite temperature, where the ground-state quasiparticle evenly splits into two branches as the temperature is increased from zero [Guenther et al., Phys. Rev. Lett. 120, 050405 (2018)]. To investigate this theoretical prediction, we employ a recently developed variational approach that systematically includes multi-body correlations between the impurity and the finite-temperature medium, thus allowing us to go beyond previous finite-temperature methods. Crucially, we find that the number of quasiparticle branches is simply set by the number of hole excitations of the thermal cloud, such that including up to one hole yields one splitting, two holes yields two splittings, and so on. Moreover, this effect is independent of the impurity mass. We thus expect that the exact ground-state quasiparticle will evolve into a single broad peak for temperatures $T>0$, with a broadening that scales as $T^{3/4}$ at low temperatures and sufficiently weak boson-boson interactions. In the zero-temperature limit, we show that our calculated ground-state polaron energy is in excellent agreement with recent quantum Monte Carlo results and with experiments.

description: In single microdisks, embedded active emitters intrinsically affect the cavity mode of microdisks, which results in a trivial symmetric backscattering and a low controllability. Here we propose a macroscopical control of the backscattering direction by optimizing the cavity size. The signature of positive and negative backscattering directions in each single microdisk is confirmed with two strongly coupled microdisks. Furthermore, the diabolical points are achieved at the resonance of two microdisks, which agrees well with the theoretical calculations considering backscattering directions. The diabolical points in active optical structures pave a way to implement quantum information processing with geometric phase in quantum photonic networks.

From this expression the equation, obtained by Kofman and Kurizki [Nature (London) 405, 546 (2000)] can be derived as a special case.

title: The Potential for the Culture of Fresh Water Fish in the United Kingdom Based on Principles of Organic Recycling and Integration with other Agricultural Systems.
Creators: name: Lawson, Simon
Publisher: name: The Open University

description: Fish culture in ponds has been practised in many countries for hundreds of years. It can be a means of producing a high quality protein food from organic wastes and from land that is unsuitable for other agricultural uses. Fish production systems are comparable to other systems of animal production for food and are subject to similar variations in intensity. In this thesis a general description of systems of fish culture is given and the relevant criteria for comparison with other animal production systems are discussed. The biological efficiencies of various systems of fish culture are investigated and compared with those of alternative agricultural systems. Increases in the efficiencies of protein production from integrating fish with livestock production are calculated. The current status of fish farming in standing water ponds in the UK is described and the potential productivity of manure fed ponds is calculated. An experiment to investigate the possibility of recycling canteen food wastes through carp is described in Chapter 5. Resource requirements, economics and marketing for fish culture in standing water ponds are also discussed.

description: Integrable deformations of type IIB superstring theory on $\mathrm{AdS}_5\times S^5$ have played an important role over the last years. The Yang-Baxter deformation is a systematic way of generating such integrable deformations. Since its introduction, this topic has seen important conceptual progress and has among others led to the intriguing discovery generalized supergravity, a new low-energy effective theory. This review endeavors to not only introduce the historical development of the Yang-Baxter deformation, but also its relation to generalized supergravity, non-geometric backgrounds, non-abelian T-duality and preserved Killing spinors. We supplement the general treatment with a wealth of explicit examples.

On the Relevance of Using Social Media Platforms as Archives for the Writing of African History
Creators: name: Englert, Birgit
name: Harisch, Immanuel R.
Year: 2020

description: In 2020, around 453 million people - roughly a third of the entire population on the African continent - were reported to be using the internet and about 217 million African users were active on social media. In this paper we suggest to understand social media platforms such as YouTube, Instagram, Twitter, Facebook and community forums as a kind of archives for writing African histories of everyday life. We argue that these platforms provide user-generated archives in the sense that they are built by users who document their everyday life by uploading items (photographs, videos, graphics, texts) which they either created themselves or which they accessed somewhere and made available by uploading them. By engaging with literature on archival science as well as on social media platforms, we discuss the opportunities which come along with the emergence of these new archives but also the ethical challenges that need to be faced when using sources from these online platforms. The article also engages with practical considerations on how to access, store and cite these sources. While many of the issues raised apply toAfrican Studies more generally, we discuss the topic with a focus on African contemporary history.
title: The population dynamics of the crested newt (Triturus Cristatus Cristatus (Laurenti)).
Creators: name: Bielinski, Andrew
Publisher: name: The Open University
Year: 1986

description: This thesis describes studies carried out on the crested newt, Triturus cristatus, and the smooth newt, T. vulgaris, at two localities in the vicinity of Milton Keynes, Buckinghamshire, between 1980 and 1983. The first study site was a pond within the grounds of the Open University at Walton Hall and the second was some 8 miles away from this near the village of Milton Bryan. At Walton Hall crested newts were intercepted during migration to the breeding pond using drift fencing and pitfall traps and by picking animals up off the road during evening searches. In this way it was found that movement was significantly correlated with daily temperature, but not with daily rainfall. In addition, it was observed that males entered the breeding pond significantly earlier than the females. At Milton Bryan a program of mark-recapture analyses was carried out on both species as the basis for the study of their population dynamics. Animals were trapped using static underwater traps and marked using toe-clips and the recording of belly-patterning. Both species were found to show variable population sizes from year to year. The sex ratio in T. vulgaris showed an excess of females in all years, whilst that of T. cristatus varied from an excess of males in some years to equality in other years. Annual survival of male and female crested newts was calculated as 0.36 for each sex. From data on weight change during the season it was found that the majority of individuals of both sexes lost weight whilst in the water. Annual growth in the crested newt was found to be highly variable, but positively correlated with body size; smaller individuals had larger increments of growth than larger individuals. However, animals of the same size did not necessarily grow by the same amount. Size-frequency distributions of both species are analysed and morphometric characteristics compared with data from other populations. The problems associated with the the extrapolation of these types of data into age-distributions are discussed, with reference to the data on growth. It is concluded that length cannot be used as reliable indicator of age in T. cristatus. From the size-frequency data it was found that the numbers of juveniles appearing at a breeding site may be highly variable from year to year. The implications of this for the dynamics of crested newt populations are discussed. Data are also presented from the dissection of preserved animals. These relate gonad size to body size in both species. It is shown that both testes weight and ovary weight are positively correlated with body weight and snout-vent length and that females display size-specific fecundity i.e. larger females produce larger ova and greater quantities of ova than smaller individuals. These findings are discussed with reference to other species of urodele and with regard to the life history tactics displayed by other species.
A legal-political commentary on the strained relationship between Africaand the International Criminal Court (ICC), and the prospects of the extended African Court of Justice and Human Rights (ACJHR)
Creators: name: Swanepoel, C. F. Neels

description: The establishment of the International Criminal Court (ICC), the world’s first and only permanent court for the investigation and prosecution of genocide, war crimes and crimes against humanity committed after 1 July 2002, has been hailed as the greatest event since the advent of the United Nations (UN). The relationship between some African states and the ICC has however becomefragile and strained. The situation has worsened since the Al-Bashir controversy,(in particular South Africa’s failure to arrest the former Sudanese President on visit in South Africa) to the extent that, in 2016, the South African government announced its intention to withdraw from the ICC. This, in South Africa, was followed by the publication of the Implementation of the Rome Statute of the International Criminal Court Act Repeal Bill (B23-2016) (which was later withdrawn) and the International Crimes Bill (B37-2017) (which later lapsed in terms of National Assembly rules). The bills provide important insights into the South African government’s approach to international crimes and criminal justice, revealing an awkward U-turn in terms of immunity granted to heads of state and senior state officials. Against that backdrop, and further with reference to the African scholarship concerning both the strained relationship between Africa, generally and the extended jurisdiction of the ACJHR, this article examines the most cited reasons for this precarious relationship. Some explanations seem more valid than others: African states’ claims that the ICC targets Africans and threatens state sovereignty on the continent simply do not hold water. On the other hand, Africa’s unease with the UN system, particularly the vexed veto system, might carry more weight, suggesting that the continent’s discontent with the ICC is less about the court itself, and more about the UN and Security Council system and composition. The article, in the last part, turns to an evaluation of the prospects of the extended African Court of Justice and Human Rights (ACJHR), which, in terms of the Malabo Protocol, would now have jurisdiction over international crimes also. Sadly, the Malabo Protocol reveals a stubborn insistence on immunity for heads of state and senior state officials, along with an ongoing fixation with state sovereignty. This does not bode well for the credibility and legitimacy of this court should it ever be formally operationalized. The continent’s political leaders should realise that it is incumbent on them to seek justice for the victims of the countless human and humanitarian rights violations committed in Africa. Clinging to outdated notions of immunity and absolute sovereignty does not offer a credible and sustainable alternative to the ICC, but represents a setback to the development of international criminal justice.
Characterization of Fouling with Hygroscopic and Non-hygroscopic Aerosols in Composite Polymer Membranes for Water Vapor Transport Applications

description: Composite membranes using a thin vapor-permeable polymer layer over a structural substrate are used in gas dehydration, food-packaging, and humidity control of indoor spaces. The impact of exposure to air pollution on the water vapor permeability and selectivity is investigated to develop an understating of potential air-side particulate fouling mechanisms and resulted performance degradation during membrane lifetime in the field. Samples of commercial membrane media were loaded with hygroscopic NaCl, and non-hygroscopic spark-generated graphite (SGG) aerosol particles. The effects of particle charge distribution and number concentration, air flowrate, temperature-gradient across membrane (Thermophoresis), and membrane surface on the rate of particle deposition were investigated using a Scanning Mobility Particle Sizer (SMPS). It was found that particle charge distribution and air flowrate had the largest impact on the rate of particle deposition. The results of permeability measurements showed that deposition of SGG and NaCl particles under a dry loading condition (RH<20%) had minimal influence on the membrane. However, when membranes loaded with hygroscopic particles in dry condition were exposed to an elevated humidity (RH>70%) leading to surface condensation, the membrane permeability reduced by up to 30%. This is hypothesized to be caused by increased resistance of microporous membrane substrate due to a pore-narrowing process. Scanning electron microscopy (SEM) combined with EDX analysis was used to examine the morphology and chemical composition of the fouled membrane surface. Analysis of SEM images showed a significant reduction in the average pore diameter of degraded samples, proportional to the fouling degree. It was also found that cleaning of fouled samples can reverse their permeability back to nearly the initial value. The reversibility of the loaded membrane permeability along with the EDX analyses imply that re-crystallization of salt ions, entrained into the pores of membrane substrate in aqueous form, is a potential explanation for the changes observed.

description: We introduce a class of simple models for shear thickening and/ or `jamming' in colloidal suspensions. These are based on schematic mode coupling theory (MCT) of the glass transition, having a memory term that depends on a density variable, and on both the shear stress and the shear rate. (Tensorial aspects of the rheology, such as normal stresses, are ignored for simplicity.) We calculate steady-state flow curves and correlation functions. Depending on model parameters, we find a range of rheological behaviours, including `S-shaped' flow curves, indicating discontinuous shear thickening, and stress-induced transitions from a fluid to a nonergodic (jammed) state, showing zero flow rate in an interval of applied stress. The shear thickening and jamming scenarios that we explore appear broadly consistent with experiments on dense colloids close to the glass transition, despite the fact that we ignore hydrodynamic interactions. In particular, the jamming transition we propose is conceptually quite different from various hydrodynamic mechanisms of shear thickening in the literature, although the latter might remain pertinent at lower colloid densities. Our jammed state is a stress-induced glass, but its nonergodicity transitions have an analytical structure distinct from that of the conventional MCT glass transition.
