description: Industry and governments have deployed computer vision models to make high-stake decisions in society. While they are often presented as neutral and objective, scholars have recognized that bias in these models might lead to the reproduction of racial, social, cultural and economic inequity. A growing body of work situates the provenance of bias in the collection and annotation of datasets that are needed to train computer vision models. This article moves from studying bias in computer vision models to the agency that is commonly attributed to them: the fact that they are universally seen as being able to make biased decisions. Building on the work of Bruno Latour and Jonathan Crary, the authors discuss computer vision models as agential optical instruments in the production of contemporary visuality. They analyse five interconnected research steps – task selection, category selection, data collection, data labelling and evaluation – of six widely cited benchmark datasets, published during a critical stage in the development of the field (2004–2020): Caltech 101, Caltech 256, PASCAL VOC, ImageNet, MS COCO and Google Open Images. They found that, despite all sorts of justifications, the selection of categories is not based on any general notion of visuality, but depends heavily upon perceived practical applications, the availability of downloadable images and, in conjunction with data collection, favours categories that can be unambiguously described by text. Second, the reliance on Flickr for data collection introduces a temporal bias in computer vision datasets. Third, by comparing aggregate accuracy rates and ‘human’ performance, the dataset papers introduce a false dichotomy between the agency of computer vision models and human observers. In general, the authors argue that the agency of datasets is produced by obscuring the power and subjective choices of its creators and the countless hours of highly disciplined labour of crowd workers.

description: This Master thesis provides a proof of concept for a novel, implantable continuous glucose sensing technology. Immobilized glucose oxidase in a poly 2-hydroxyethyl methacrylate hydrogel is used to enzymatically convert an increase in glucose level to a local decrease in pH, which leads to a swelling of the hydrogel. Encapsulated gold nanoparticles in the gel allow an optical readout of the glucose concentration. Experimental methods include hydrogel synthesis, nanoparticle encapsulation and finally glucose sensing with the hydrogel by UV-vis measurements. Two possible readouts, absorbance change and frequency shift, are discussed and tested. While a frequency shift is not detected, results show that the absorbance of the gel is proportional to glucose level, making it a promising concept for continuous glucose monitoring.

description: This paper presents a sociolinguistic perspective on language in the Internet. Most linguistic research on computer mediated communication has focused on media or genre related language variation, establishing language styles as typical for e.g. chat or newsgroups. A critical discussion of this research suggests that more attention should be paid to user related language variation. The concept of ‚online community‘ is proposed as a suitable starting point for the study of language variation on the Internet, and sociological and linguistic criteria for the definition and description of online communities are discussed. The second part of the paper presents a classification of sociolinguistically relevant variation patterns. Finally, evidence for the effect of various social factors on language use in the Internet is reviewed.

description: Background/Aims:Dietary composition has been shown to affect acid-base homeostasis and bone health in humans. We investigated the potential renal acid load (PRAL) and the estimated diet-dependent net acid load (net endogenous acid production, NEAP) in adult vegans and evaluated the relationships between NEAP, food groups and intake of bone health-related nutrients. Methods: The German Vegan Study (GVS) is a cross-sectional study. Data from healthy men (n = 67) and women (n = 87), aged 21–75 years, who fulfilled the study criteria (vegan diet for ≧1 year prior to study start; age ≧18 years, and no pregnancy/childbirth during the last 12 months) were included in the analysis. NEAP values were calculated from diet composition using two models: one based on the protein/potassium quotient and another taking into account an anthropometry-based loss of urinary organic anions. Results:Mean daily intakes of phosphorus, potassium, sodium, magnesium and vitamin C were above, and vitamin D and calcium below Dietary Reference Intake (DRI). Regardless of the model used, the diet in the GVS was characterized by a nearly neutral NEAP. A strong correlation was observed between the NEAP values of the two models (rs = 0.873, p < 0.001). Only the consumption of fruits decreased constantly across the increasing quartiles of NEAP. Conclusions: It can be hypothesized that vegan diets do not affect acid-base homeostasis. With respect to bone health, the significance of this finding needs further investigation.

description: In this paper we consider a two-phase model describing the growth of avascular solid tumors when taking into account the effects of cell-to-cell adhesion and taxis due to nutrient. The tumor is surrounded by healthy tissue which is the source of nutrient for tumor cells. In a three-dimensional context, we prove that the mathematical formulation corresponds to a well-posed problem, and find radially symmetric steady-state solutions of the problem. They appear in the regime where the rate of cell apoptosis to cell proliferation is less than the far field nutrient concentration. Furthermore, we study the stability properties of those radially symmetric equilibria and find, depending on the biophysical parameters involved in the problem, both stable and unstable regimes for tumor growth.

description: In the present study the biodiversity of the most abundant phototrophic organisms forming biological soil crust communities were determined, which included green algae, diatoms, yellow-green algae and lichens in samples collected on Ardley and King George islands, Maritime Antarctic. The species were identified by their morphology using light microscopy, and for lichen identification thin layer chromatography as also used to separate specific secondary metabolites. Several sources of information were summarized in an algae catalogue. The results revealed a high species-richness in Antarctic soil crust communities with 127 species in total. Of which, 106 taxa belonged to algae (41 Chlorophyta, nine Streptophyta, 56 Heterokontophyta) and 21 to lichens in 13 genera. Moreover, soil crust communities with different species compositions were determined for the various sampling locations, which might reflect microclimatic and pedological gradients. © 2017 Antarctic Science Ltd.

description: In this study we examine statistical properties of traffic generated by the popular P2P IPTV application SopCast. The analysis aims at a better understanding of the mechanisms used by such applications and their impact on the network. Since the most popular P2P IPTV applications use proprietary unpublished protocols, we look directly at the generated traffic focusing on a single session analysis, which is the major contribution of our work. We present a basic characterisation of the traffic profile generated by SopCast during every separate session in terms of the intensity, the burstiness, the distribution of the packet sizes and the correlation. We show that some of these statistical properties of the analysed traffic may be quite different depending on the particular session.

description: We report development and measurement of a micro-fabricated compact high-temperature superconducting (HTS) metamaterial atom operating at a frequency as low as $\sim$ 53MHz. The device is a planar spiral resonator patterned out of a {YBa$_2$Cu$_3$O$_{7-δ}$} (YBCO) thin film with the characteristic dimension of $\sim λ_0/1000$, where $λ_0$ is the free-space wavelength of the fundamental resonance. While deployment of an HTS material enables higher operating temperatures and greater tunability, it has not compromised the quality of our spiral metamaterial atom and a Q as high as $\sim 1000$ for the fundamental mode, and $\sim 30000$ for higher order modes, are achieved up to 70K. Moreover, we have experimentally studied the effect of the substrate by comparing the performance of similar devices on different substrates.

description: We discuss charm production at the LHC. The production of single $c \bar c$ pairs is calculated in the $k_t$-factorization approach. We use Kimber-Martin-Ryskin unintegrated gluon distributions in the proton. The hadronization is included with the help of Peterson fragmentation functions. Transverse momentum and pseudorapidity distributions of charmed mesons are presented and compared to recent results of the ALICE, LHCb and ATLAS collaborations. Furthermore we discuss production of two pairs of $c \bar c$ within a simple formalism of double-parton scattering (DPS). Surprisingly large cross sections, comparable to single-parton scattering (SPS), are predicted for LHC energies. We discuss perspectives how to identify the double scattering contribution. We predict much larger cross section for large rapidity distance between charm quarks from different hard parton scatterings compared to single scattering.

description: The soraphens are natural products that exhibit a molecular structure different from what would have been expected by following its polyketidal assembly line. The most significant differences are the presence of a hemiketal instead of a trisubstituted double bond and a double bond at C9 and C10 where a saturated carbon chain was expected. We were interested in the biological activity of the soraphens with architectures as described by the polyketide synthase since we hypothesized that these modifications reflect the evolutionary optimization of the soraphens. Herein we describe four additional derivatives of the so-called paleo-soraphens and their biological profiling to provide a picture of the hypothetical evolutionary optimization of this family of natural products. The syntheses required a unified and convergent strategy and their biological profiling was performed with the aid of impedance measurements. The results of these biological experiments are consistent with the proposed evolutionary optimization of the soraphens.
title: Essays on the political economy of the Eurozone and Greek

Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: This dissertation is about the Eurozone and Greek crises of the 2010s, comprising of three papers, an introduction and a conclusion. The three papers respectively analyse the political, financial and economic dimensions of the crises. Paper 1 shows that double-sided incomplete information is a necessary condition for explaining the bargaining dynamics and outcome of the third Greek bailout negotiations. Our model also demonstrates that the outcome of the negotiations was not that predictable. Finally, the Greek policy-makers could have been more aggressive to increase their chance of obtaining a better deal. Paper 2 then investigates the effect of political uncertainty on Greek sovereign spreads between October 2009 and July 2012. We thus create a dataset comprising of more than 5800 news items covering most policy debates prevailing at that time and that are manually coded along several dimensions, in particular as expected or unexpected policy developments. The results using an EGARCH(1,1) specification suggest that financial markets reacted strongly to unexpected positive policy developments but remained, on the whole, more sensitive to negative developments in line with existing findings. Finally, paper 3 studies the role played by uncertainty in the protracted slump of investment following the Great Recession and Eurozone crisis. Since existing volatility-based proxies for uncertainty may discount uncertainty shocks coming from the left tail, we create a proxy for disaster risk building on the Growth-at-Risk approach. Using Bayesian VAR models on a panel of 12 advanced economies from 1997Q1 to 2019Q3, we find no conclusive effect of disaster risk shocks on investment.
title: Commercial determinants of health in sport. The example of the English Premier League

Publisher: name: University of Glasgow

description: Introduction: Transnational alcohol, food, beverage and gambling industries market their unhealthy brands to sport’s global audiences. However, there has been little research on the commercial determinants of health in sport and the world’s most popular sport and competition - football’s English Premier League (EPL). Methods: I conducted four inter-linked studies to assess the commercial determinants of health in a case study of the EPL: 1) An internet scoping study of the sponsorship deals of EPL clubs in the 2018/19 and 2019/20 football seasons. 2) A content analysis of visual references to unhealthy brands during five EPL matches broadcast on subscription television in 2019. 3) The marketing strategies used by four EPL sponsors drawn from the gambling, food, beverage and alcohol industries. 4) A qualitative study capturing the stakeholders’ views about unhealthy brand sponsorship in football. Findings: The EPL and its member clubs have multiple partners drawn from the unhealthy commodity industries. Gambling brands are most prominent both in club sponsorships and during ‘live’ football programmes. The brands appear both on players’ shirts and in pitch perimeter advertising. Sophisticated marketing strategies then activate traditional and digital methods to engage fans as consumers. Stakeholders’ views on sponsorship reflect their level of economic and cultural capital. Discussion and Conclusions: This study has described the marketing practices of unhealthy commodity industries in the EPL. Given that it has been demonstrated by others that this marketing is likely to damage the health of football’s global audience of fanconsumers, a more ethical approach to sport sponsorship deserves consideration.

description: Developing of new rare-earth (RE)-doped optical fibres for power amplifiers and lasers requires continuous improvements in the fibre spectroscopic properties (like shape and width of the gain curve, optical quantum efficiency, resistance to spectral hole burning and photodarkening...). Silica glass as a host material for fibres has proved to be very attractive. However, some potential applications of RE-doped fibres suffer from limitations in terms of spectroscopic properties resulting from clustering or inappropriate local environment when doped into silica. To this aim, we present a new route to modify some spectroscopic properties of RE ions in silica-based fibres based on the incorporation of erbium ions in amorphous dielectric nanoparticles, grown in-situ in fibre preforms. By adding alkaline earth elements, in low concentration into silica, one can obtain a glass with an immiscibility gap. Then, phase separation occurs under an appropriate heat treatment. We investigated the role of three alkaline-earth elements: magnesium, calcium and strontium. We present the achieved stabilisation of nanometric erbium-doped dielectric nanoparticles within the core of silica fibres. We present the nanoparticle dimensional characterisation in fibre samples. We also show the spectroscopic characterisation of erbium in preform and fibre samples with different compositions. This new route could have important potentials in improving RE-doped fibre amplifiers and laser sources.

description: Epitaxial layers of insulating binary lanthanide oxides have been considered as potential alternative to conventional SiO2 for gate dielectric application in future Si-based MOSFET devices, which was investigated in more detail for epitaxial Gd2O3 and Nd2O3 as model systems. Additionally, the ability to integrate epitaxial dielectric barrier layers into Si structures can usher also in a variety of novel applications involving oxide/silicon/oxide heterostructures in diverse nanoelectronic and quantum-effect devices. Although epitaxial layers of such ionic oxides with excellent structural quality can be grown using molecular beam epitaxy, they often exhibit poor electrical properties such as high leakage current density, flat band instability, poor reliability etc. owing to the presence of electrically active charge defects, generated either during the oxide layer growth or typical subsequent CMOS process steps. Based on the origin and individual character of these defects, we review various aspects of defect prevention and passivation which lead to a significant improvement in the dielectric properties of the heterostructures.

description: When a film of a liquid suspension of nanoparticles or a polymer solution is deposited on a surface, it may dewet from the surface and as the solvent evaporates the solute particles/polymer can be deposited on the surface in regular line patterns. In this paper we explore a hydrodynamic model for the process that is based on a long-wave approximation that predicts the deposition of irregular and regular line patterns. This is due to a self-organised pinning-depinning cycle that resembles a stick-slip motion of the contact line. We present a detailed analysis of how the line pattern properties depend on quantities such as the evaporation rate, the solute concentration, the Péclet number, the chemical potential of the ambient vapour, the disjoining pressure, and the intrinsic viscosity. The results are related to several experiments and to depinning transitions in other soft matter systems.

description: In a recent article in this journal, Geoffrey Hodgson points out that the notion of 'evolution' is widely used in organization science without authors being sufficiently clear on what exactly they mean by this term. In his article, Hodgson cleans up the terminological and conceptual confusion on evolution in organization science and positions so-called 'generalized Darwinism' as the only well-elaborated evolutionary framework available in social science. We doubt, however, whether in its present form generalized Darwinism itself constitutes a viable approach. In this article we argue that Hodgson and collaborators so far have failed to show that generalized Darwinism is actually capable of serving as a basis for the construction of evolutionary explanations of social and organizational phenomena. We suggest a few items that should be put on generalized Darwinism's research agenda in order to develop it towards a viable option. © The Author(s) 2013.

description: We describe a novel coarse-grained simulation method for modelling the dynamics of globular macromolecules, such as proteins. The macromolecule is treated as a continuum that is subject to thermal fluctuations. The model includes a non-linear treatment of elasticity and viscosity with thermal noise that is solved using finite element analysis. We have validated the method by demonstrating that the model provides average kinetic and potential energies that are in agreement with the classical equipartition theorem. In addition, we have performed Fourier analysis on the simulation trajectories obtained for a series of linear beams to confirm that the correct average energies are present in the first two Fourier bending modes. We have then used the new modelling method to simulate the thermal fluctuations of a representative protein over 500ns timescales. Using reasonable parameters for the material properties, we have demonstrated that the overall deformation of the biomolecule is consistent with the results obtained for proteins in general from atomistic molecular dynamics simulations.

description: The main purpose of this article is to make Astronomers aware that Searches for Extraterrestrial Intelligence can be carried out by analyzing standard astronomical spectra, including those they already have taken. Simplicity is the outstanding advantage of a search in spectra. The spectra can be analyzed by simple eye inspection or a few lines of code that uses Fourier transform software. Theory, confirmed by published experiments, shows that periodic signals in spectra can be easily generated by sending light pulses separated by constant time intervals. While part of this article, like all articles on searches for ETI, is highly speculative the basic physics is sound. In particular, technology now available on Earth could be used to send signals having the required energy to be detected at a target located 1000 light years away. Extraterrestrial Intelligence (ETI) could use these signals to make us aware of their existence. For an ETI, the technique would also have the advantage that the signals could be detected both in spectra and searches for intensity pulses like those currently carried out on Earth.

description: Modern wind turbines turn their blades along their primary axis to control the conversion of aerodynamic power. The pitch bearings connect the rotor hub of the turbine with the blades and allow this rotation. They are large slewing bearings with diameters in the range of 2 - 7 m. In comparison to bearings in other applications, pitch bearings suffer from three particularities: Oscillating movements instead of full rotations, dynamic and stochastic loads in five degrees of freedom instead of controlled loads, and interface parts with low and complex stiffness along the circumference instead of almost stiff connections. The capital costs of the bearings and even more the costs connected to failures make it paramount to mitigate operational risks of new designs. As there are no established calculation methods for the most dominant damage modes of pitch bearings, bearing tests are of critical value to this risk mitigation. This work covers the design of endurance test runs for pitch bearings. A true endurance test run of pitch bearings should result in a profound evaluation of the risk of failure during the lifetime of the wind turbine. This goal makes the design of an endurance run a substantial task. It gets even more challenging when such a test run needs to fit into the overall turbine design process, both in matters of timing and finance. This work results in a test run profile that covers wear and fatigue damage modes of the bearing rollers and raceways, among others. It also covers the development and commissioning of the test environment for different bearing sizes. The IWT7.5-164 reference turbine serves as example for the design of the test environment and the test run.

description: Using Monte Carlo integration techniques, we investigate running coupling effects compatible with the high energy bootstrap condition to all orders in the strong coupling in evolution equations valid at small values of Bjorken x in deep inelastic scattering. A model for the running of the coupling with analytic behavior in the infrared region and compatible with power corrections to jet observables is used. As a difference to the fixed coupling case, where the momentum transfer acts as an effective strong cut-off of the diffusion to infrared scales, in our running coupling study the dependence on the momentum transfer is much milder.

subject: Unlimited Farsightedness

description: We study the stability of trade policy arrangements under two regulatory scenarios, with/without PTAs. Unlike previous papers, we consider an extensive set of trade policy constellations and allow for unlimited farsightedness of negotiating parties. We find global free trade (GFT) to be uniquely stable under symmetry, with/without PTAs. When two countries are smaller(larger) than the third, availability of PTAs decreases (increases) the stability of GFT. Away from symmetry, GFT is not attainable, and without PTAs the non-cooperative MFN regime is the only stable outcome. The effect of (dis-)allowing PTAs thus depends on the size asymmetry of countries.

description: A total of 41,825 metal-organic frameworks (MOFs) were computationally screened toward the design of amine-functionalized MOFs for CO2 separation. Both the optimal species and number of amine functional groups were examined for eight MOFs with good performance in terms of CO2 uptake and selectivity. It was revealed that more amine functional groups grafted on the MOFs do not lead to a better CO2 separation capability, and the concept of saturation degree of functional groups was proposed. The ethylene-diamine-functionalized MOF-74 membrane was predicted to possess high CO2 permeation separation capability, which was confirmed by the parallel experimental test of gas permeation.

description: An isotope dilution method for the quantitative analysis of trace elements in biological samples and for the characterization of reference materials for the analysis of biological samples by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-ID-MS) has been tested. Polymeric thin layers with 5–10 μm thickness containing the ID-spike and the correction standard were produced by knife application onto polyester substrates. For the ID experiments 204Pb enriched lead was used, and bismuth served as the internal standard. The layers showed good homogeneity of the layer thickness and the distribution of added elements. For the testing of the ID method, a synthetic sample with lead and a lead containing polymer certified reference material (BAM H010) have been used. Mass fractions for lead calculated after single and double isotope dilution experiments in the test samples showed a deviation of less than 1% from the certified values.
