[more ▼]This paper explores empirically the reasons why some banks issue Contingent Convertible Bonds while others do not. For this purpose we use a binary logistic model and control for the determinants suggested by the literature on optimal capital structure which considers four drivers of capital structure: corporate taxes, costs of financial distress, agency costs and asymmetric information.. Our findings suggest that the banks with bigger size and those with higher Tier 1 capital, higher net loans, higher wholesale funding, lower level of leverage and lower risk weighted assets have a higher tendency to issue CoCos. Our results also suggest that banks in countries with higher annual growth rate of GDP per capita and those listed as G-SIBs are more likely to issue CoCos.

[more ▼]We study how the institutional arrangements for ending deliberation --- the "cloture rules" --- interact with collective learning to affect the outcomes of decision making in committees. In contrast to much of the previous literature on deliberative commit tees, this paper makes a distinction between the final votes over policy proposals and the cloture votes that bring them about. Using this approach, we explore how cloture rules influence the course of deliberation, the likelihood of inefficient deliberative outcomes, the circumstances surrounding failures to bring proposals to a final vote, and the distribution of power among committee members in the deliberative process. We also use our simple model to examine the issue of the stability of cloture rules, characterizing the rules that no coalition of committee members is able or willing to overturn. We show in particular that all cloture rules are dynamically stable.

[more ▼]This paper studies the complementarity between domestic and foreign skilled workers. It develops a simple model where employers seek to recruit a foreign worker when finding domestic workers takes more time. This paper confirms the predictions of the model. I rely on a within-firm within-occupation identification strategy to compare recruitment decisions made by a given employer for similar positions that differ in job posting duration. To identify this relationship, I have collected and assembled a new and original dataset at the job level. I match online job postings to administrative data on labor condition applications (LCAs) submitted as the first step in applying for H-1B temporary skilled worker visas. I find that employers are 28 percent more likely to submit an LCA when the job posting duration is one standard deviation longer. I provide evidence suggesting that this phenomenon is due to insufficient domestic labor supply in these occupations.

[more ▼]In this paper, I investigate how cultural differences affect the labor-market performance of immigrant workers in Germany. I document a negative relationship between hourly wages and the cultural distance between immigrants' countries of origin and Germany. This result is robust across the three main indicators used in the gravity literature: linguistic, religious, and genetic distances. This cultural wage penalty disappears after five to ten years spent in Germany. Controlling for language proficiency as well as for selective in- and out-migration, these results highlight the cultural integration of immigrant workers. I finally provide evidence suggesting that lower wage progression may be explained by fewer job-to-job transitions.

[more ▼]Spheroids encapsulated within alginate capsules are emerging as suitable in vitro tools to investigate the impact of mechanical forces on tumor growth since the internal tumor pressure can be retrieved from the deformation of the capsule. Here we focus in particular on the Cellular Capsule Technology (CCT). We show in this contribution that a modeling approach accounting for the triphasic nature of the spheroid (extracellular matrix, tumor cells and interstitial fluid) offers a new perspective of analysis revealing that the pressure retrieved experimentally cannot be interpreted as a direct picture of the pressure sustained by the tumor cells and, as such, cannot therefore be used to quantify the critical pressure which induces stress-induced phenotype switch in tumour cells. The proposed multiphase reactive poro-mechanical model was cross-validated. Parameter sensitivity analyses on the digital twin revealed that the main parameters determining the encapsulated growth configuration are different from those driving growth in free condition, confirming that radically different phenomena are at play.Results reported in this contribution support the idea that multiphase reactive poro-mechanics is an exceptional theoretical framework to attain an in-depth understanding of CCT experiments, to confirm their hypotheses and to further improve their design.

The ... [more ▼]The classical Weyl problem (solved by Lewy, Alexandrov, Pogorelov, and others) asks whether any metric of curvature K≥0 on the sphere is induced on the boundary of a unique convex body in $\R^3$. The answer was extended to surfaces in hyperbolic space by Alexandrov in the 1950s, and a dual'' statement, describing convex bodies in terms of the third fundamental form of their boundary (e.g. their dihedral angles, for an ideal polyhedron) was later proved. We describe three conjectural generalizations of the Weyl problem in $\HH^3$ and its dual to unbounded convex subsets and convex surfaces, in ways that are relevant to contemporary geometry since a number of recent results and well-known open problems can be considered as special cases. One focus is on convex domain having a thin'' asymptotic boundary, for instance a quasicircle -- this part of the problem is strongly related to the theory of Kleinian groups. A second direction is towards convex subsets with a thick'' ideal boundary, for instance a disjoint union of disks -- here one find connections to problems in complex analysis, such as the Koebe circle domain conjecture. A third direction is towards complete, convex disks of infinite area in $\HH^3$ and surfaces in hyperbolic ends -- with connections to questions on circle packings or grafting on the hyperbolic disk. Similar statements are proposed in anti-de Sitter geometry, a Lorentzian cousin of hyperbolic geometry where interesting new phenomena can occur, and in Minkowski and Half-pipe geometry. We also collect some partial new results mostly based on recent works.

[more ▼]We aim at estimating the invariant density associated to a stochastic differential equation with jumps in low dimension, which is for d = 1 and d = 2. We consider a class of jump diffusion processes whose invariant density belongs to some Hölder space. Firstly, in dimension one, we show that the kernel density estimator achieves the convergence rate 1/T, which is the optimal rate in the absence of jumps. This improves the convergence rate obtained in [Amorino, Gloter (2021)], which depends on the Blumenthal-Getoor index for d = 1 and is equal to log T/T for d = 2. Secondly, we show that is not possible to find an estimator with faster rates of estimation. Indeed, we get some lower bounds with the same rates { 1/T , log T/T } in the mono and bi-dimensional cases, respectively. Finally, we obtain the asymptotic normality of the estimator in the one-dimensional case. [less ▲]Detailed reference viewed: 15 (1 UL) Border or bordering practice?

[more ▼]In Border Studies, the ongoing discussions on methodological and theoretical questions have led to the development of transformed approaches and vocabulary for border research. This contribution highlights the shift from ‘border’ to ‘bordering practice’ and questions its sources in the scientific context, such as the cultural turn and the related practice turn. Despite the popular use of the term ‘practice’ in Border Studies, sociological practice theories are not at the center of the development of dynamic concepts for studying borders. The article emphasizes the compatibility of sociological practice theories with the practice and process orientation in Border Studies. It gives a short overview of praxeological thinking in sociology and identifies methodological challenges for Border Studies targeting the development of praxeological re-search perspectives for borders.

Finally, we present a preliminary take on their formal specification, using ideas from multi-agent logics.

[more ▼]To date, the resolution of the Banco Popular Español, being the first and only resolution case in the euro area, has had the “benefit” of bringing to light several shortfalls of this crisis management system. Back then, thanks to the sale of business, the need of the use of the Single Resolution Fund (SRF) has been avoided, prompting criticism on whether the fund had sufficient means to overcome a major widespread crisis. During the period elapsed from the last financial crisis, the euro area banking sector has built capital and liquidity buffers, which were aimed at protecting them for future shocks. Although it is now widely accepted that crises are of a cyclical nature, new risks and the high interconnectivity of today’s economic activities brought an unexpected crisis due to the current pandemic. The consequences of this unprecedented event in modern history had severe effects to the worldwide economy, mostly for the boundless block of labour activities, which caused severe losses for households, enterprises and governments that consequently affected the financial intermediation function of the banks. Concerning the European Stability Mechanism (ESM), the current pandemic has had the effect to put temporary on hold the discussion on the revision of the ESM Treaty, including its role as a Backstop to the SRF, so that the Mechanism could experience a new role through the ESM Pandemic Crisis Support. In such a framework, this paper aims to bring back the attention to the unfinished path in the establishment of the Common Backstop by addressing an important element of risk, namely its decision-making process. The main aim is to explore possible governance issues, which could hamper a timely and effective use of the Common Backstop, in the case that the SRF would be depleted and no alternative funding sources would be available.

[more ▼]Motivated by recent discussions about the issue of risk perceptions for climate change related events, we introduce a non-cooperative game setting where agents manage a common pool resource under a potential risk, and agents exhibit different risk perception biases. Focusing on the effect of the polarization level and other population features, we show that the type of bias (overestimation versus underestimation biases) and the resource quality level before and after the occurrence of the shift have first-order importance on the qualitative nature of behavioral adjustments and on the pattern of resource conservation. When there are non-uniform biases within the population, the intra-group structure of the population qualitatively affects the degree of resource conservation. Moreover, unbiased agents may react in nonmonotone ways to changes in the polarization level when faced with agents exhibiting different types of bias. The size of the unbiased agents’ sub-population does not qualitatively affect how an increase in the polarization level impacts individual behavioral adjustments, even though it affects the magnitude of this change. Finally, it is shown how perception biases affect the comparison between centralized and decentralized management.

[more ▼]We introduce a hybrid "Modified Genetic Algorithm-Multilevel Stochastic Gradient Descent" (MGA-MSGD) training algorithm that considerably improves accuracy and efficiency of solving 3D mechanical problems described, in strong-form, by PDEs via ANNs (Artificial Neural Networks). This presented approach allows the selection of a number of locations of interest at which the state variables are expected to fulfil the governing equations associated with a physical problem. Unlike classical PDE approximation methods such as finite differences or the finite element method, there is no need to establish and reconstruct the physical field quantity throughout the computational domain in order to predict the mechanical response at specific locations of interest. The basic idea of MGA-MSGD is the manipulation of the learnable parameters’ components responsible for the error explosion so that we can train the network with relatively larger learning rates which avoids trapping in local minima. The proposed training approach is less sensitive to the learning rate value, training points density and distribution, and the random initial parameters. The distance function to minimise is where we introduce the PDEs including any physical laws and conditions (so-called, Physics Informed ANN). The Genetic algorithm is modified to be suitable for this type of ANN in which a Coarse-level Stochastic Gradient Descent (CSGD) is exploited to make the decision of the offspring qualification. Employing the presented approach, a considerable improvement in both accuracy and efficiency, compared with standard training algorithms such classical SGD and Adam optimiser, is observed. The local displacement accuracy is studied and ensured by introducing the results of Finite Element Method (FEM) at sufficiently fine mesh as the reference displacements. A slightly more complex problem is solved ensuring the feasibility of the methodology [less ▲]Detailed reference viewed: 56 (0 UL) Development and Validation of the Revised Multicultural Ideology Scale in Germany and LuxembourgStogianni, Maria ; Berry, John; Grigoryev, Dmitry et alE-print/Working paper (2020)A revised version of the Multicultural Ideology Scale (rMCI; Berry 2020; Berry et al., 1977) is currently being developed to measure endorsement of multiculturalism in different cultural contexts.

[more ▼]A revised version of the Multicultural Ideology Scale (rMCI; Berry 2020; Berry et al., 1977) is currently being developed to measure endorsement of multiculturalism in different cultural contexts. The current study, which is part of this cross-cultural research project, presents the first assessment of the rMCI scale in the German language. The measure aims to cover several attitudinal dimensions of multiculturalism, relevant to the integration of different ethnocultural groups: Cultural Maintenance, Equity/Inclusion, Social interaction, Essentialistic Boundaries, Extent of Differences, and Consequences of Diversity. Two independent datasets were acquired from Germany (N = 382) and Luxembourg (N = 148) to estimate the factor structure of the rMCI using different confirmatory factor analysis techniques. The findings suggest that a 4-factor solution, including Cultural Maintenance, Equity/Inclusion, Social interaction, and Consequences of Diversity, was the best fit for the data. Most of these subscales demonstrated adequate psychometric properties (internal consistency, convergent, and discriminant validity). The 4-factor model of the rMCI was partially invariant across the two ethnic groups and full measurement invariance was established across gender.

[more ▼]In this paper, I propose to isolate the role of age as a self-selection factor of international migration. The role of age is estimated on intended emigration rather than on observed outcomes of migration, using individual measures of intended emigration drawn from a large-scale survey conducted by Gallup. I find evidence that age has a monotonic negative effect on desired emigration for the working-age population. The estimations point to a very robust effect, suggesting that an additional year of age decreases the probability of intended emigration by about 0.5%. This effect is steady over different periods of time and for most types of countries of origin. The results contrast with previous evidence obtained on observed outcomes of migration, suggesting that out-selection factors interact with age and shape the demographic profile of migrants.

[more ▼]Over the last century, we observe a steady and exponentially growth of scientific publications globally. The overwhelming amount of available literature makes a holistic analysis of the research within a field and between fields based on manual inspection impossible. Automatic techniques to support the process of literature review are required to find the epistemic and social patterns that are embedded in scientific publications. In computer sciences, new tools have been developed to deal with large volumes of data. In particular, deep learning techniques open the possibility of automated end-to-end models to project observations to a new, low-dimensional space where the most relevant information of each observation is highlighted. Using deep learning to build new representations of scientific publications is a growing but still emerging field of research. The aim of this paper is to discuss the potential and limits of deep learning for gathering insights about scientific research articles. We focus on document-level embeddings based on the semantic and relational aspects of articles, using Natural Language Processing (NLP) and Graph Neural Networks (GNNs). We explore the different outcomes generated by those techniques. Our results show that using NLP we can encode a semantic space of articles, while with GNN we are able to build a relational space where the social practices of a research community are also encoded.

[more ▼]In this paper, we consider a one-dimensional diffusion process with jumps driven by a Hawkes process. We are interested in the estimations of the volatility function and of the jump function from discrete high-frequency observations in long time horizon. We first propose to estimate the volatility coefficient. For that, we introduce in our estimation procedure a truncation function that allows to take into account the jumps of the process and we estimate the volatility function on a linear subspace of L 2 (A) where A is a compact interval of R. We obtain a bound for the empirical risk of the volatility estimator and establish an oracle inequality for the adaptive estimator to measure the performance of the procedure. Then, we propose an estimator of a sum between the volatility and the jump coefficient modified with the conditional expectation of the intensity of the jumps. The idea behind this is to recover the jump function. We also establish a bound for the empirical risk for the non-adaptive estimator of this sum and an oracle inequality for the final adaptive estimator. We conduct a simulation study to measure the accuracy of our estimators in practice and we discuss the possibility of recovering the jump function from our estimation procedure.

From the continuous observa- tion of the sampling path on [0, T ] we show that, under anisotropic H ̈older smoothness constraints, kernel based estimators can achieve fast convergence rates. In particu- lar, they are as fast as the ones found by Dalalyan and Reiss [9] for the estimation of the invariant density in the case without jumps under isotropic H ̈older smooth- ness constraints. Moreover, they are faster than the ones found by Strauch [29] for the invariant density estimation of continuous stochastic differential equations, under anisotropic H ̈older smoothness constraints. Furthermore, we obtain a minimax lower bound on the L2-risk for pointwise estimation, with the same rate up to a log(T) term. It implies that, on a class of diffusions whose invariant density belongs to the anisotropic Holder class we are considering, it is impossible to find an estimator with a rate of estimation faster than the one we propose.

[more ▼]Cultural products are a source to acquire individual values and behaviours. Therefore, the differences in the content of the magazines aimed specifically at women or men are a means to create and reproduce gender stereotypes. In this study, we compare the content of a women-oriented magazine with that of a men-oriented one, both produced by the same editorial group, over a decade (2008-2018). With Topic Modelling techniques we identify the main themes discussed in the magazines and quantify how much the presence of these topics differs between magazines over time. Then, we performed a word-frequency analysis to validate this methodology and extend the analysis to other subjects that did not emerge automatically. Our results show that the frequency of appearance of the topics Family, Business and Women as sex objects, present an initial bias that tends to disappear over time. Conversely, in Fashion and Science topics, the initial differences between both magazines are maintained. Besides, we show that in 2012, the content associated with horoscope increased in the women-oriented magazine, generating a new gap that remained open over time. Also, we show a strong increase in the use of words associated with feminism since 2015 and specifically the word abortion in 2018. Overall, these computational tools allowed us to analyse more than 24,000 articles. Up to our knowledge, this is the first study to compare magazines in such a large dataset, a task that would have been prohibitive using manual content analysis methodologies [less ▲]Detailed reference viewed: 10 (0 UL) Getzler-Kapranov complexes and moduli stacks of curvesKalugin, Alexey E-print/Working paper (2020)Detailed reference viewed: 66 (2 UL) SARS-CoV-2 Transmission in Educational Settings During an Early Summer Epidemic Wave in LuxembourgMossong, Joël; Mombaerts, Laurent ; Veiber, Lisa et alE-print/Working paper (2020)Background: The role of schools and children in the transmission of SARS-CoV-2 remains to be determined.

[more ▼]Background: The role of schools and children in the transmission of SARS-CoV-2 remains to be determined. Following a first wave in spring and gradual easing of lockdown, Luxembourg experienced an early second epidemic wave before the start of summer school holidays on 15th July. This provided the opportunity to study the role of school-age children and school settings in SARS-CoV-2 transmission. More specifically, we compared the incidence in school-age children, teachers and the general working population, and estimated the number of secondary transmissions occurring at schools using contact tracing data. Findings: While SARS-CoV-2 incidence was much higher in adults aged 20 and above than in children aged 0 to 19 during the first wave in spring, no significant difference was found during the second wave in early summer. The incidence during the second wave was similar for pupils, teachers and the general working population. Based on a total of 424 reported confirmed COVID-19 cases in school-age children and teachers, we estimate that 179 index cases caused 49 secondary transmissions in schools. While some small clusters of mainly student-to-student transmission within the same class were identified, we did not observe any large outbreaks with multiple generations of infection. Interpretation: Transmission of SARS-CoV-2 within Luxembourg schools was limited during the early summer epidemic wave in 2020. Precautionary measures including physical distancing as well as easy access to testing, systematic contact tracing appears to have been successful in mitigating transmission within educational settings.

[more ▼]Let M be a differentiable manifold endowed with a family of complete Riemannian metrics g(t) evolving under a geometric flow over the time interval [0,T[. In this article, we give a probabilistic representation for the derivative of the corresponding conjugate semigroup on M which is generated by a Schrödinger type operator. With the help of this derivative formula, we derive fundamental Harnack type inequalities in the setting of evolving Riemannian manifolds. In particular, we establish a dimension-free Harnack inequality and show how it can be used to achieve heat kernel upper bounds in the setting of moving metrics. Moreover, by means of the supercontractivity of the conjugate semigroup, we obtain a family of canonical log-Sobolev inequalities. We discuss and apply these results both in the case of the so-called modified Ricci flow and in the case of general geometric flows.

These solutions, that we call $\log\Gamma_p$-type functions, include various special functions such as the polygamma functions, the logarithm of the Barnes $G$-function, and the Hurwitz zeta function. Our results generalize to any nonnegative integer $p$ the special case when $p=1$ obtained by Krull and Webster, who both generalized Bohr-Mollerup-Artin's characterization of the gamma function. We also follow and generalize Webster's approach and provide for $\log\Gamma_p$-type functions analogues of Euler's infinite product, Weierstrass' infinite product, Gauss' limit, Gauss' multiplication formula, Legendre's duplication formula, Euler's constant, Stirling's constant, Stirling's formula, Wallis's product formula, and Raabe's formula for the gamma function. We also introduce and discuss analogues of Binet's function, Burnside's formula, Fontana-Mascheroni's series, Euler's reflection formula, and Gauss' digamma theorem. Lastly, we apply our results to several special functions, including the Hurwitz zeta function and the generalized Stieltjes constants, and show through these examples how powerful is our theory to produce formulas and identities almost systematically.

[more ▼] Machine learning based methods for diagnosis and progression prediction of COVID-19 from imaging data have gained significant attention in the last months, in particular by the use of deep learning models. In this context hundreds of models where proposed with the majority of them trained on public datasets. Data scarcity, mismatch between training and target population, group imbalance, and lack of documentation are important sources of bias, hindering the applicability of these models to real-world clinical practice. Considering that datasets are an essential part of model building and evaluation, a deeper understanding of the current landscape is needed. This paper presents an overview of the currently public available COVID-19 chest X-ray datasets. Each dataset is briefly described and potential strength, limitations and interactions between datasets are identified. In particular, some key properties of current datasets that could be potential sources of bias, impairing models trained on them are pointed out. These descriptions are useful for model building on those datasets, to choose the best dataset according the model goal, to take into account the specific limitations to avoid reporting overconfident benchmark results, and to discuss their impact on the generalisation capabilities in a specific clinical setting.

We fully answer this question for immersions with principal curvatures in (−1,1): while the only local obstructions are the conditions that G is Lagrangian and Riemannian, the global obstruction is more subtle, and we provide two characterizations, the first in terms of the Maslov class, and the second (for M compact) in terms of the action of the group of compactly supported Hamiltonian symplectomorphisms [less ▲]Detailed reference viewed: 15 (0 UL) Symposium on Oumar Ba’s Book ‘States of Justice: The Politics of the International Criminal Court’–Introductory PostOwiso, Owiso E-print/Working paper (2020)Detailed reference viewed: 80 (0 UL) The Flow of Information Among Authorities Involved in the Banking Union’s Resolution Procedure: The Case of the SRB and the ECBLupinu, Pier Mario E-print/Working paper (2020)The flow of information is vital for the smooth functioning and certainty of the successful outcome of a resolution procedure during resolution planning and execution.

[more ▼]The flow of information is vital for the smooth functioning and certainty of the successful outcome of a resolution procedure during resolution planning and execution. As a result, the exchange of relevant information has become highly influential in current debates. This article will focus on the exchange of information between the Single Resolution Board (SRB) and the European Central Bank (ECB). Firstly, the Authorities decided to arrange the rules for sharing information bilaterally in the form of a Memorandum of Understanding (MoU). While this framework of cooperation and exchange of information between the SRB and the ECB constitutes an obligation under Article 30(7) of the Single Resolution Mechanism Regulation (SRMR), it was drafted in the non-binding form of an MoU. The general purpose of an MoU is to establish the basis for cooperation and convergence of intentions. Such foundations aim to strengthen the resolution procedure by joining forces to obtain more accurate and complete data with better coordination of tasks and resources in order to achieve the most solid result possible within a tighter timeframe.

[more ▼]Unmanned aerial vehicle (UAV) communication has emerged as a prominent technology for emergency communications (e.g., natural disaster) in Internet of Things (IoT) networks to enhance the ability of disaster prediction, damage assessment, and rescue operations promptly. In this paper, a UAV is deployed as a flying base station (BS) to collect data from time-constrained IoT devices and then transfer the data to a ground gateway (GW). In general, the latency constraint at IoT users and the limited storage capacity of UAV highly hinder practical applications of UAV-assisted IoT networks. In this paper, full-duplex (FD) technique is adopted at the UAV to overcome these challenges. In addition, half-duplex (HD) scheme for UAV-based relaying is also considered to provide a comparative study between two modes (viz., FD and HD). Herein, a device is successfully served iff its data is collected by UAV and conveyed to GW within the flight time. In this context, we aim at maximizing the number of served IoT devices by jointly optimizing bandwidth and power allocation, as well as the UAV trajectory, while satisfying the requested timeout (RT) requirement of each device and the UAV’s limited storage capacity. The formulated optimization problem is troublesome to solve due to its non-convexity and combinatorial nature. Toward appealing applications, we first relax binary variables into continuous values and transform the original problem into a more computationally tractable form. By leveraging inner approximation framework, we derive newly approximated functions for non-convex parts and then develop a simple yet efficient iterative algorithm for its solutions. Next, we attempt to maximize the total throughput subject to the number of served IoT devices. Finally, numerical results show that the proposed algorithms significantly outperform benchmark approaches in terms of the number of served IoT devices and the amount of collected data.

[more ▼]While the hierarchy of science'' has been widely analysed, there is no corresponding study of the status of subfields within a given scientific field. We use bibliometric data to show that subfields of mathematics have a different standing'' within the mathematics community. Highly ranked departments tend to specialize in some subfields more than in others, and the same subfields are also over-represented in the most selective mathematics journals or among recipients of top prizes. Moreover this status of subfields evolves markedly over the period of observation (1984--2016), with some subfields gaining and others losing in standing. The status of subfields is related to different publishing habits, but some of those differences are opposite to those observed when considering the hierarchy of scientific fields. We examine possible explanations for the status'' of different subfields. Some natural explanations -- availability of funding, importance of applications -- do not appear to function, suggesting that factors internal to the discipline are at work. We propose a different type of explanation, based on a notion of focus'' of a subfield, that might or might not be specific to mathematics.

[more ▼]Election verifiability aims to ensure that the outcome produced by electronic voting systems correctly reflects the intentions of eligible voters, even in the presence of an adversary that may corrupt various parts of the voting infrastructure. Protecting such systems from manipulation is challenging because of their distributed nature involving voters, election authorities, voting servers and voting platforms. An adversary corrupting any of these can make changes that, individually, would go unnoticed, yet in the end will affect the outcome of the election. It is, therefore, important to rigorously evaluate whether the measures prescribed by election verifiability achieve their goals. We propose a formal framework that allows such an evaluation in a systematic and automated way. We demonstrate its application to the verification of various scenarios in Helios and Belenios, two prominent internet voting systems. For Helios, our analysis is the first one to be, at the same time, fully automated (with the Tamarin protocol prover) and to precisely capture its end-to-end verifiability guarantees, allow- ing us to derive new security proofs and new attacks on deployed versions of it. For Belenios, similarly, we capture precisely the end-to-end verifiability guarantees when all election authorities are corrupted, which is outside the scope of previous formal definitions. We also find new attacks that apply in weaker corruption scenarios that are expected to be secure. In general, our framework allows a unified analy- sis and comparison of cryptographic voting protocols, corruption scenarios and verifiability procedures towards ensuring the end goal of election integrity.

[more ▼]The COVID-19 took by surprise most Member States of the European Union, as they underestimated the rapid spread of the contagion in the continent. The response of the Member States was asymmetrical, individualistic and significantly slow. The first measures taken were to close down the internal borders. The response of the European Union was even slower to the point that and it was not until March 17th 2020 that the external borders were closed. These actions affected legal migration into the European Union from four perspectives: 1) it affected the mobility of those third country nationals who were on temporary stay in the Member States; 2) the entry of third country nationals to do seasonal work; 3) the entry and stay of legal migrants; and 4) the status quo of the third country nationals already residing in the Member States, especially those who have a loss of income. This article will deal with the measures taken by Member States on who to manage the immigration services during the crisis as well as the measures taken in order to deal with overstayers, seasonal workers and other legal migrants. Finally, we will focus in the vulnerable situation that third-country national salaried workers are exposed due to the loss of income or loss of employment in the Member States and the risk of being returned to their country of origin.

[more ▼]The interpretation of the number of COVID-19 cases and deaths in a country or region is strongly dependent on the number of performed tests. We developed a novel SIR based epidemiological model (SIVRT) which allows the country-specific integration of testing information and other available data. The model thereby enables a dynamic inspection of the pandemic and allows estimating key figures, like the number of overall detected and undetected COVID-19 cases and the infection fatality rate. As proof of concept, the novel SIVRT model was used to simulate the first phase of the pandemic in Luxembourg. An overall number of infections of 13.000 and an infection fatality rate of 1,3 was estimated, which is in concordance with data from population-wide testing. Furthermore based on the data as of end of May 2020 and assuming a partial deconfinement, an increase of cases is predicted from mid of July 2020 on. This is consistent with the current observed rise and shows the predictive potential of the novel SIVRT model.

[more ▼]The accelerated digitalisation of society along with technological evolution have extended the geographical span of cyber-physical systems. Two main threats have made the reliable and real-time control of these systems challenging: (i) uncertainty in the communication infrastructure induced by scale, openness and heterogeneity of the environment and devices; and (ii) targeted attacks maliciously worsening the impact of the above-mentioned communication uncertainties, disrupting the correctness of real-time applications. This paper addresses those challenges by showing how to build distributed protocols that provide both real-time with practical performance, and scalability in the presence of network faults and attacks. We provide a suite of real-time Byzantine protocols, which we prove correct, starting from a reliable broadcast protocol, called PISTIS, up to atomic broadcast and consensus. This suite simplifies the construction of powerful distributed and decentralized monitoring and control applications, including state-machine replication. Extensive empirical evaluations show- case PISTIS’s robustness, latency, and scalability. For example, PISTIS can withstand message loss (and delay) rates up to 40% in systems with 49 nodes and provides bounded delivery latencies in the order of a few milliseconds.

[more ▼]Over three years have passed since 29 March 2017, the date when the United Kingdom (UK) triggered Article 50 of the Treaty on European Union (TEU). This date has become well-known, for paving the way to multiple legal issues, which mostly depend on the finalisation of an agreement setting the conditions for the future relations between the European Union (EU) and the UK. Despite recent political declarations, the Brexit outcome is now clear, and a transitional period has just begun. As a result, for the resolution of credit institutions established in the EU, the bail-in of liabilities previously established under English law could become problematic. To date, the EU framework for the resolution of credit institutions (namely, the Bank Recovery and Resolution Directive – BRRD) lacks a provision for the direct recognition of liabilities governed under third-country law. However, through its Article 55, the BRRD leaves to the EU Member State (MS) the duty to require entities to include “resolution-proof” clauses or, alternatively, to conclude a binding agreement with the relevant third country. This leaves a legislative gap concerning this direct recognition. By analysing the current EU legal framework for the bail-in of liabilities established with contracts governed by third-country law, with a view to identify its weaknesses, this paper aims at addressing possible practical solutions. The purpose is to ease the resolution process for the relevant administrative authority of the EU MS in charge of the resolution procedure, without the need of an immediate intervention of the legislator. Indeed, a solution for such gap in the BRRD might be disentangled outside the Brexit withdrawal agreement, or with specific arrangements between the EU/EU MS and the UK administrative authorities.

Genome-wide association analysis identified five independent risk loci, whereas genome-wide gene-aggregation tests implicated mutations in the gene GBA. Genetic risk scores demonstrate that LBD shares risk profiles and pathways with Alzheimer’s and Parkinson’s disease, providing a deeper molecular understanding of the complex genetic architecture of this age-related neurodegenerative condition.Competing Interest StatementThomas G.

[more ▼]We prove using an integral criterion the existence and completeness of the wave operators corresponding to the Hodge-Laplacians acting on differential p-forms, induced by two quasi-isometric Riemannian metrics g and h on a complete open smooth manifold M. In particular, this result provides a criterion for the absolutely continuous spectra to coincide. The proof is based on gradient estimates obtained by probabilistic Bismut-type formulae for the heat semigroup defined by spectral calculus. By these localised formulae, the integral criterion only requires local curvature bounds and some upper local control on the heat kernel acting on functions, but no control on the injectivity radii. A consequence is a stability result of the absolutely continuous spectrum under a Ricci flow. As an application we concentrate on the important case of conformal perturbations.

The workshop intended to take stock of developments at the European, national and sub-national levels given the European Union’s wrap up of its decade-long Education & Training 2020 strategy (ET 2020), a framework for cooperation in education and training. However, on March 12, we had to cancel the physical meeting on short notice due to the coronavirus crisis. In the following, we share our experiences with the subsequent transition to an alternative online workshop format that took place on April 23, involving 25 participants from 10 countries, and 16 paper presentations. After sketching the workshop’s virtual setup, we discuss strengths, weaknesses, and challenges related to this digital transition. Furthermore, we explore the prospects of such online formats for future academic conferences and networking."

[more ▼]Coding and non-coding RNAs have diagnostic and prognostic importance in Parkinson’s diseases (PD). We studied circulating small non-coding RNAs (sncRNAs) in 7, 003 samples from two longitudinal PD cohorts (Parkinson’s Progression Marker Initiative (PPMI) and Luxembourg Parkinson’s Study (NCER-PD)) and modelled their influence on the transcriptome. First, we sequenced sncRNAs in 5, 450 blood samples of 1, 614 individuals in PPMI. The majority of 323 billion reads (59 million reads per sample) mapped to miRNAs. Other covered RNA classes include piRNAs, rRNAs, snoRNAs, tRNAs, scaRNAs, and snRNAs. De-regulated miRNAs were associated with the disease and disease progression and occur in two distinct waves in the third and seventh decade of live. Originating mostly from a characteristic set of immune cells they resemble a systemic inflammation response and mitochondrial dysfunction, two hallmarks of PD. By profiling 1, 553 samples from 1, 024 individuals in the NCER-PD cohort using an independent technology, we validate relevant findings from the sequencing study. Finally, network analysis of sncRNAs and transcriptome sequencing of the original cohort identified regulatory modules emerging in progressing PD patients.Competing Interest StatementThe authors have declared no competing interest.

[more ▼]We define a model of international trade with two countries, two vertically differentiated goods, and heterogenous consumers concerning their willingness to pay for quality. Trade generates two sources of pollution: the production of domestic and traded goods, and their transportation between countries. Consumers in both countries manifest home bias which translates into ethnocentric preferences: (i) consumer perceive the quality of the domestic good amplified; and (ii) consumers thrive additional satisfaction when consuming a domestic good rather than a foreign one since only the former can satisfy their sense of place. By contrast, they suffer a psychological penalty when consuming a foreign product. We investigate the role of trade costs and ethnocentric attitude in shaping the equilibrium configuration of the international duopoly. Finally, we uncover the environmental damage from production and from transport in presence of ethnocentrism.

[more ▼]Let λ− and λ+ be two bounded measured laminations on the hyperbolic disk H2, which "strongly fill" (definition below). We consider the left earthquakes along λ− and λ+, considered as maps from the universal Teichmüller space T to itself, and we prove that the composition of those left earthquakes has a fixed point. The proof uses anti-de Sitter geometry. Given a quasi-symmetric homeomorphism u:RP1→RP1, the boundary of the convex hull in AdS3 of its graph in RP1×RP1≃∂AdS3 is the disjoint union of two embedded copies of the hyperbolic plane, pleated along measured geodesic laminations. Our main result is that any pair of bounded measured laminations that "strongly fill" can be obtained in this manner.

[more ▼]BACKGROUND: After the World Health Organization declared the outbreak of coronavirus disease to be a public health emergency of international concern on January 30, 2020, the first SARS-CoV-2 infection was detected in Luxembourg on February 29, 2020. Representative population-based data, including asymptomatic individuals for assessing the viral spread and immune response were, however, lacking worldwide. METHODS: Using a panel-based method, we implemented a representative sample of the Luxembourgish population based on age, gender and residency for testing for SARS-CoV-2 infection and antibody status in order to define prevalence irrespective of clinical symptoms. Participants were contacted via email to fill an online questionnaire before biosampling at local laboratories. All participants provided information related to clinical symptoms, epidemiology, socioeconomic and psychological assessments and underwent biosampling, rRT-PCR testing and serology for SARS-CoV-2. RESULTS: We included a total of 1862 individuals in our representative sample of the general Luxembourgish population. Of these, 5 individuals had a current positive result for infection with SARS-CoV-2 based on rRT-PCR. Four of these individuals were oligosymptomatic and one was asymptomatic. Overall we found a positive IgG antibody status in 35 individuals (1.97%), of which 11 reported to be tested positive by rRT-PCR for SARS-CoV-2 previously and showed in addition their IgG positive status also a positive status for IgA. Our data indicate a prevalence of 0.3% for active SARS-CoV-2 infection and an infection rate of 2.15% in the Luxembourgish population between 18 and 79 years of age. CONCLUSIONS: Luxembourgish residents show a low rate of acute infections after 7 weeks of confinement and present with an antibody profile indicative of a more recent immune response to SARS-CoV-2. All infected individuals were oligo- or asymptomatic. Bi-weekly follow-up visits over the next 2 months will inform about the viral spread by a- and oligosymptomatic carriers and the individual changes in the immune profile.Competing Interest StatementThe authors have declared no competing interest.Clinical TrialNCT04379297Funding StatementThe CON-VINCE Study is funded by the Research Fund Luxembourg (FNR; CON-VINCE) and the André Losch Foundation (Luxembourg).Author DeclarationsAll relevant ethical guidelines have been followed; any necessary IRB and/or ethics committee approvals have been obtained and details of the IRB/oversight body are included in the manuscript.YesAll necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

[more ▼]The present study examined the dimensionality and the measurement invariance of the Multicultural Ideology Scale (MCI; Berry & Kalin, 1995), and mean differences across different cultural groups within the multilingual, multicultural context of Luxembourg. With 47% of the citizens being non-nationals, minority and majority are increasingly difficult to define and Luxembourg becomes a unique context to study attitudes towards diversity. Our sample included 1488 participants from diverse ethnic backgrounds who completed the survey in German, French or English. In contrast to previous findings, our analyses revealed a two-dimensional structure, distinguishing between positive and negative attitudes towards multiculturalism. The factor structure was partially invariant across ethnocultural groups: Configural and metric invariance were established across natives and non-natives, scalar invariance only across gender groups. Natives and male participants reported more negative attitudes towards multiculturalism. We discuss the importance of assessing measurement invariance and provide recommendations to improve the assessment of psychological multiculturalism.

[more ▼]Contact tracing is an important instrument for national health services to fight epidemics. As part of the COVID-19 situation, many proposals have been made for scaling up contract tracing capacities with the help of smartphone applications, an important but highly critical endeavor due to the privacy risks involved in such solutions. Extending our previously expressed concern, we clearly articulate in this article, the functional and non-functional requirements that any solution has to meet, when striving to serve, not mere collections of individuals, but the whole of a nation, as required in face of such potentially dangerous epidemics. We present a critical information infrastructure, PriLock, a fully-open preliminary architecture proposal and design draft for privacy preserving contact tracing, which we believe can be constructed in a way to fulfill the former requirements. Our architecture leverages the existing regulated mobile communication infrastructure and builds upon the concept of "checks and balances", requiring a majority of independent players to agree to effect any operation on it, thus preventing abuse of the highly sensitive information that must be collected and processed for efficient contact tracing. This is enforced with a largely decentralised layout and highly resilient state-of-the-art technology, which we explain in the paper, finishing by giving a security, dependability and resilience analysis, showing how it meets the defined requirements, even while the infrastructure is under attack.

[more ▼]Today, leveraging the enormous modular power, diversity and flexibility of manycore systems-on-a-chip (SoCs) requires careful orchestration of complex resources, a task left to low-level software, e.g. hypervisors. In current architectures, this software forms a single point of failure and worthwhile target for attacks: once compromised, adversaries gain access to all information and full control over the platform and the environment it controls. This paper proposes Midir, an enhanced manycore architecture, effecting a paradigm shift from SoCs to distributed SoCs. Midir changes the way platform resources are controlled, by retrofitting tile-based fault containment through well known mechanisms, while securing low-overhead quorum-based consensus on all critical operations, in particular privilege management and, thus, management of containment domains. Allowing versatile redundancy management, Midir promotes resilience for all software levels, including at low level. We explain this architecture, its associated algorithms and hardware mechanisms and show, for the example of a Byzantine fault tolerant microhypervisor, that it outperforms the highly efficient MinBFT by one order of magnitude.

[more ▼]I evaluate Christine Lagarde´s claim that more female leaders can be associated with more prudence, and less of the risky decision-making that had provoked the crisis. Indeed, the proportion of women who are employed in decision-making and management roles in governments, large enterprises and institutions varies substantially across European countries and is oftentimes below 30%. Research suggests that in addition to biological differences, men and women show morphological dissimilarities in specific brain regions, which explain the observed differences in behavior. As a result, female decision makers tend to be more risk averse, better suited to carefully analyze a problem, superior in multitasking and better in creating solutions that work for a group. Not surprisingly, firms with more female decision makers tend to outperform their peers in terms of productivity, profitability and stock performance while taking fewer risks. In this paper, I aim to explore the effect of female decision making on aggregate equity returns. Relying on an equilibrium asset-pricing model in an economy under jump diffusion, I decompose the moments of the returns of European stock market indices into a diffusive (systematic) risk and an (idiosyncratic) extreme event risk part. For a balanced panel of European countries, I find empirical evidence for a Lehman sisters’ effect: female decision making is an important determinant of (idiosyncratic) extreme event risk. As a result, stock markets in countries with more female decision makers are characterized by higher risk aversion, lower volatility and more positive return asymmetry, primarily driven by extreme event risk, e.g. the lower frequency of negative jumps. Results are robust to the inclusion of various controls for other country- or market-specific characteristics.

[more ▼]Research suggests that systematic tail risk affects the cross-sectional variation in hedge fund returns. Fund’s tail risk is mainly induced by its investments in more tail-sensitive stocks and is positively related to a trading strategy of writing out-of-the-money put options on the equity market index. Hence, high tail risk hedge funds are exposed to higher moments risks; they sell market volatility risk and buy market skewness risk. The relationship between the return spread of a high minus low tail risk strategy and a market volatility factor is expected to be negative and empirically observed to be negative. However, the relationship between a tail risk strategy and a market skewness factor is expected to be positive but I find it to be negative. In this paper, I explore this puzzling result. Using equity-oriented hedge fund return data, I find that equity market skewness risk explains a major part of variations in hedge funds’ tail risk. My results suggest that the observed negative relationship relates to the problem of price pressure associated with “crowded trades” of mutual funds. Given that retail investors are prone to herding, the directional trading of mutual funds is correlated, and their collective actions can generate short-term price pressure on aggregate stock prices (price ‘noise’). Short sellers systematically exploit these patterns not only in the equity lending market, but also in the options market by moving in the opposite direction. Hence, in times when investors shift their funds from bond to equity mutual funds, short selling in the options market, the non-fundamental demand for index put options, induces a negative relationship between risk-neutral market skewness and returns. Accordingly, the long leg of the tail risk strategy appears to be negatively exposed to market skewness risk, which is in contrast to the usual interpretation of option-implied skewness as an indicator of jump risk. My results are in line with empirical evidence that suggests that the shape of the implied volatility curve is attributable to the demand pressure of specific option series and a limited ability of arbitrageurs to bring prices back into alignment.

[more ▼]V rámci projektu BMC-EU (Základní pohybové kompetence v Evropě) byla vyvinuta sada nástrojů pro školení učitelů, skládající se z koncepce školení učitelů a doprovodné uživatelské příručky (intelektuální výstup BMC-EU 4) za účelem podpory implementace modulární podpůrné sady nástrojů na základě konceptu základních pohybových kompetencí (intelektuální výstup BMC-EU 3; Scheuer & Heck, 2020). Cílem této podpůrné sady nástrojů je zavedení do praxe především na úrovni pravidelných hodin tělesné výchovy tak, aby bylo možno začít s přizpůsobováním obsahu a metod výuky tělesné výchovy. Sada nástrojů pro školení učitelů obsahuje materiály pro realizaci školení rozdělené do teoretické a praktické části. V první části jsou učitelé seznámeni s konceptem MOBAK, měřením, testovacím postupem, zpracováním a vyhodnocováním dat a s interpretací výsledků testů. Ve druhé části se naučí, jak dospět od diagnostiky základních pohybových kompetencí studentů a od silných a slabých stránek identifikovaných při hodnocení k tomu, jak konkrétně zasáhnout pomocí podpůrného rámce MOBAK a doprovodných podpůrných materiálů ve formě modulární podpůrné sady nástrojů, která je připravena k zavádění do praxe v konkrétních vzdělávacích situacích za účelem podpory studentů s dalšími potřebami v základních pohybových kompetencích. Vzhledem k tomu, že sada nástrojů pro školení učitelů má za cíl podporovat a usnadňovat implementaci Modulární podpůrné sady pro učitele (Scheuer & Heck, 2020) založenou na konceptu a měření MOBAK (Herrmann, 2018), v celém tomto dokumentu se na podpůrnou sadu nástrojů a na testovací příručku MOBAK odkazuje.

[more ▼]Im Rahmen des BMC-EU Projekts (Basic Motor Competencies in Europe) wurde ein Toolkit für die Fortbildung von Sportlehrkräften entwickelt, welches aus einem Fortbildungskonzept inklusive eines Handbuchs (BMC-EU intellectual output 4) besteht. Die Entwicklung dieses Fortbildungskonzepts soll dazu beitragen, dass das modulare Support Toolkit auf der Basis des Konzepts der motorischen Basiskompetenzen (BMC-EU intellectual output 3; Scheuer & Heck, 2020) eingesetzt wird. Das Ziel dieses Support Toolkits ist hauptsächlich der Einsatz auf der Ebene des regulären Sportunterrichts um die Anpassungen, welche den Inhalt und die Methoden des Unterrichtens betreffen, voranzutreiben. Das Toolkit für die Fortbildung von Lehrkräften beinhaltet Materialen, die für die Durchführung einer strukturierten Lehrerfortbildung sowohl im theoretischen als auch im praktischen Teil benötigt werden. Im ersten Schritt werden die Lehrkräfte mit dem MOBAK Konzept, der Datenerhebung, der Testdurchführung, der Datenverarbeitung und –evaluation sowie mit der Interpretation der Testergebnisse vertraut gemacht. Im zweiten Schritt lernen die Lehrkräfte wie sie auf die Stärken und Schwächen ihrer Schülerinnen und Schüler, welche die Ergebnisse aus den Tests zu den motorischen Basiskompetenzen zeigen, fördern können, indem sie das MOBAK Support Toolkit verwenden. Dieses Toolkit kann direkt in konkrete Unterrichtsszenarien eingesetzt werden, um die Schülerinnen und Schüler mit zusätzlichem Förderbedarf in den motorischen Kompetenzen zu unterstützen. Da das Toolkit für die Fortbildung von Lehrkräfte darauf abzielt, die Durchführung des modularen Support Toolkits für Lehrkräfte (Scheuer & Heck, 2020) basierend auf dem MOBAK Konzept (Herrmann, 2018) zu unterstützen und zu ermöglichen, wird in diesem Dokument immer wieder auf das Support Toolkit und das MOBAK Testmanual verwiesen.

[more ▼]V rámci projektu BMC-EU (Základní pohybové kompetence v Evropě) byl na základě koncepce základních pohybových kompetencí a výsledků sběru dat vytvořen rámec podpory a vzorová sada nástrojů (výsledek první fáze projektu – intelektuální výstup 3). Účelem této sady je nabídnout variabilní přístup k metodice tělesné výchovy. V první fázi projektu byl vytvořen podpůrný rámec pro diagnostiku základních pohybových kompetencí žáků, jejich silných a slabých stránek z pohledu základních pohybových způsobilostí. Na základě tohoto rámce byly vyvinuty podklady ve formě vzorové podpůrné sady (didaktických) materiálů, připravených k implementaci v konkrétních vzdělávacích situacích, jejichž účelem je rozvoj základních pohybových kompetencí diagnostikovaných žáků. Vzorová podpůrná sada nástrojů obsahuje pokyny pro interpretaci výsledků testů MOBAK (Motorische Basiskompetenzen), podpůrný rámec MOBAK, glosář a vzorovou podpůrnou sadu nástrojů s materiály pro učitele tělesné výchovy ve formě karet MOBAK. Karty MOBAK popisují činnosti a aktivity dle principů variace (rozličnosti podnětů) a jsou založeny na přístupu orientovaném na kompetence.

[more ▼]No enquadramento do projeto BMC-EU (Competências motoras básicas na Europa), a ferramenta para a formação de professores consistindo num conceito de formação de professores juntamente com um manual de utilização (BMC-EU intellectual output 4) foi desenvolvido de modo a apoiar a implementação do kit modular de ferramentas para suporte aos professores considerando o conceito de competências motoras básicas (BMC-EU intellectual output 3; Scheuer & Heck, 2020). O objetivo deste kit de ferramentas de suporte é ser implementado principalmente ao nível da educação física regular para iniciar adaptações relativas ao conteúdo e métodos na instrução da educação física. A ferramenta de apoio à formação de professores contém materiais para implementar a formação de professores estruturada, com uma parte teórica e outra prática. Num primeiro passo, os professores estão familiarizados com o conceito MOBAK, medição, procedimentos do teste, tratamento dos dados e avaliação assim como com a interpretação dos resultados do teste. Numa segunda parte eles aprendem como diagnosticar as competências motoras básicas dos alunos e as forças e fraquezas identificadas na avaliação para concretizar intervenções usando o quadro de referência de suporte MOBAK e as fichas que acompanham o Kit de suporte, prontos para serem implementados em situações educativas concretas para apoiar estudantes com necessidades acrescidas nas competências motoras básicas. Como a ferramenta para a formação de professores visa apoiar e facilitar a implementação do Kit modular de ferramentas para suporte aos professores (Scheuer & Heck, 2020) baseado no conceito e medição do MOBAK (Herrmann, 2018), ao longo deste manual são fornecidas referências para suportar o kit de apoio e o manual do teste MOBAK .
