Let $K\subset \HH^3$ be a convex subset in $\HH^3$ with smooth, strictly convex boundary. The induced metric on $\partial K$ then has curvature $K>-1$. It was proved by Alexandrov that if $K$ is bounded, then it is uniquely determined by the induced metric on the boundary, and any smooth metric with curvature $K>-1$ can be obtained. We propose here an extension of the existence part of this result to unbounded convex domains in $\HH^3$. The induced metric on $\partial K$ is then clearly not sufficient to determine $K$. However one can consider a richer data on the boundary including the ideal boundary of $K$. Specifically, we consider the data composed of the conformal structure on the boundary of $K$ in the Poincar\'e model of $\HH^3$, together with the induced metric on $\partial K$. We show that a wide range of "reasonable" data of this type, satisfying mild curvature conditions, can be realized on the boundary of a convex subset in $\HH^3$. We do not consider here the uniqueness of a convex subset with given boundary data. [less ▲]

The rising quality and throughput demands of the manufacturing domain require flexible, accurate and explainable computer-vision solutions for defect detection. Deep Neural Networks (DNNs) reach state-of-the-art performance on various computer-vision tasks but wide-spread application in the industrial domain is blocked by the lacking explainability of DNN decisions. A promising, human-readable solution is given by saliency maps, heatmaps highlighting the image areas that influence the classifier’s decision. This work evaluates a selection of saliency methods in the area of industrial quality assurance. To this end we propose the distance pointing game, a new metric to quantify the meaningfulness of saliency maps for defect detection. We provide steps to prepare a publicly available dataset on defective steel plates for the proposed metric. Additionally, the computational complexity is investigated to determine which methods could be integrated on industrial edge devices. Our results show that DeepLift, GradCAM and GradCAM++ outperform the alternatives while the computational cost is feasible for real time applications even on edge devices. This indicates that the respective methods could be used as an additional, autonomous post-classification step to explain decisions taken by intelligent quality assurance systems. [less ▲]

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.

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.

Microdiversity, the organization of microorganisms into groups with closely related but ecologically different sub-types, is widespread and represents an important linchpin between microbial ecology and evolution. However, the drivers of microdiversification remain largely unknown. Here we show that selection promotes microdiversity in the microbiome associated with sediments in glacier-fed streams (GFS). Applying a novel phylogenetic framework, we identify several clades that are under homogeneous selection and that contain genera with higher levels of microdiversity than the rest of the genera. Overall these clades constituted ~44% and ~64% of community α-diversity and abundance, and both percentages increased further in GFS that were largely devoid of primary producers. Our findings show that strong homogeneous selection drives the microdiversification of specialized microbial groups putatively underlying their success in the extreme environment of GFS. This microdiversity could be threatened as glaciers shrink, with unknown consequences for microbial diversity and functionality in these ecosystems. [less ▲]

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. [less ▲]

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.

Identifying the impact of incapacitation measures on crime, such as imprisonment or curfews, is challenging since any such intervention simultaneously dissuades from engaging in illegal behaviour. We exploit Covid-19 confinement measures as a quasi-experiment to isolate incapacitative from deterrent effects of mobility restrictions in a developing country, Ecuador. Difference-in-differences and event-study estimates show a significant reduction in violent and property crime, relative to comparable months in pandemic-free years. While the fall in violent crime is driven by rape cases, we observe no cross-crime substitution for property crime. Heterogeneity effect analysis indicates that the composite decline in violent crime is entirely attributed to incapacitation. In contrast, the drop in property crime is attenuated in provinces where the economic activity mainly relies on essential sectors and blue-collar occupations, leaving incapacitation to explain 40 to 50% of the composite decrease.

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 ▲]

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. [less ▲]

We study the problem of the non-parametric estimation for the density π of the stationary distribution of the multivariate stochastic differential equation with jumps (Xt)0≤t≤T , when the dimension d is such that d ≥ 3. 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.

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. [less ▲]

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 ▲]

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.

 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.

Given an oriented immersed hypersurface in hyperbolic space H^{n+1}, its Gauss map is defined with values in the space of oriented geodesics of H^{n+1}, which is endowed with a natural para-Kähler structure. In this paper we address the question of whether an immersion G of the universal cover of an n-manifold M, equivariant for some group representation of π1(M) in Isom(H^{n+1}), is the Gauss map of an equivariant immersion in H^{n+1}. 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 ▲]

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.

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. [less ▲]

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. [less ▲]

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.

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. [less ▲]

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. [less ▲]

Im Rahmen dieser Newsletter wird analysiert, in welchem Umfang Arbeitnehmer in Luxemburg an ihrem Arbeitsplatz von der Frustration dreier psychologischer Grundbedürfnisse – der Autonomie, der Kompetenz, und der Verbundenheit – betroffen sind. Hierbei zeigt sich durchgängig bei den Arbeitnehmern, dass die Frustration über fehlende Autonomie am Stärksten ausgeprägt ist. Spezifische Arbeitsbedingungen, wie z.B. fehlende Partizipation sowie geringes Well-Being sindzudem besonders hoch mit Frustration korreliert. Vergleiche zwischen unterschiedlichen Arbeitnehmergruppen zeigen auf, dass Frauen gegenüber Männern ein etwas höheres Ausmaß der Frustration von Verbundenheit und von Kompetenz erleben. Manager zeigen hingegen ein geringeres Ausmaß der Frustration von Verbundenheit im Vergleich zu Arbeitnehmern in anderen Berufen. Arbeitnehmer, die in NGOs arbeiten, weisen wiederum das geringste Ausmaß an Frustration über fehlende Autonomie auf. [less ▲]

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.

The genetic basis of Lewy body dementia (LBD) is not well understood. Here, we performed whole-genome sequencing in large cohorts of LBD cases and neurologically healthy controls to study the genetic architecture of this understudied form of dementia and to generate a resource for the scientific community. 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.

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. [less ▲]

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.

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. [less ▲]

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.

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.

Moments of crisis like the current one sparked by Covid-19, engage social, economic, cultural and political institutions of a society and stress-test their resourcefulness, while individual and collective food supplies become primary concerns. Where does even the wealthiest of EU member States stand when it comes to food sovereignty and specific vulnerabilities, what needs to change and which food policies are needed to facilitate a sustainable food system – both locally and internationally? Combining qualitative, empirical research methods to textual and statistical analysis, as well as transformative research, I focus on key areas of Luxembourg’s food system presenting challenges – specific ones and structural ones intertwined with issues in other countries – and discuss current and planned pathways of optimisation. I will start out with an analysis of agricultural and commercial specificities of a food system with low self-sufficiency rates, linked to meat and dairy specialisations, but also to market accessibility and market structure issues, leading to heavy imports. I will then shed light on pathways currently put into practice by the State, by economic actors, by educational actors and by social movements and coalitions of the willing, advocating ecological, ethical and qualitative production methods. Finally, I will show how the first Food Policy Council at national level that Luxembourg is currently founding is favoring a deliberate shift towards a multi-stakeholder-lead effective food policy.

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.

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. [less ▲]

Dans le cadre du projet BMC-EU (Compétences motrices de base en Europe), une boîte à outils pour la formation des enseignants reprenant le concept de formation ainsi qu’un manuel d'utilisation (BMC-EU production intellectuelle 4) a été développée afin de soutenir la mise en œuvre de la formation aux tests MOBAK (boîte à outils pour l’enseignant-support théorique) la base du concept de compétences motrices de base (BMC-EU production intellectuelle 3 ; Scheuer & Heck, 2020). L'objectif de cette boîte à outils de soutien est d'être mis en œuvre principalement au niveau des cours réguliers d'éducation physique pour aider les enseignants d’éducation physique à adapter leurs contenus et leurs méthodes d'enseignement. La boîte à outils pour la formation des enseignants présente les éléments à mettre en œuvre lors de formations d'enseignants. Celles-ci sont structurées en une partie théorique et une partie pratique. Dans un premier temps, les enseignants sont familiarisés avec le concept MOBAK, la mesure, la procédure de test, le traitement des données et l’évaluation ainsi qu'avec l'interprétation des résultats du test. Dans une deuxième partie, ils apprennent à passer du diagnostic des compétences motrices de base des élèves et des forces et faiblesses identifiées dans l'évaluation à des interventions concrètes en utilisant le cadre de soutien MOBAK et les documents qui l'accompagnent sous la forme d'un support théorique (boîte à outils pour l’enseignant), prêt à être mis en œuvre dans des situations éducatives concrètes pour soutenir les élèves ayant des besoins supplémentaires en compétences motrices de base. Étant donné que la boîte à outils pour la formation des enseignants vise à soutenir et à faciliter la mise en œuvre de la formation théorique des enseignants de soutien modulaire pour les enseignants (Scheuer et Heck, 2020), il sera fait référence au concept et au construit des tests MOBAK (Herrmann, 2018), et au manuel de test MOBAK tout au long de ce document.

Στο πλαίσιο του έργου BMC-EU (Βασικές Κινητικές Δεξιότητες στην Ευρώπη), αναπτύχθηκε μία εργαλειοθήκη κατάρτισης για εκπαιδευτικούς, αποτελούμενη από τη γενική πρακτική ιδέα και ένα συνοδευτικό εγχειρίδιο χρήστη (BMC-EU πνευματική παραγωγή 4), για να υποστηρίξει την εφαρμογή της υποστηρικτικής εργαλειοθήκης με βάση την έννοια των βασικών κινητικών δεξιοτήτων (BMC-EU πνευματική παραγωγή 3; Scheuer & Heck, 2020). Ο σκοπός της εργαλειοθήκης αυτής είναι να εφαρμοστεί στα μαθήματα φυσικής αγωγής, ώστε να προσαρμοστούν κατάλληλα τόσο το περιεχόμενο όσο και οι μέθοδοι διδασκαλίας της φυσικής αγωγής. Η εργαλειοθήκη κατάρτισης για εκπαιδευτικούς περιέχει υλικό για τη δημιουργία πρακτικών προγραμμάτων για εκπαιδευτικούς δομημένα τόσο σε θεωρητικό, όσο και πρακτικό επίπεδο. Αρχικά, οι εκπαιδευτικοί εξοικειώνονται με την έννοια του ΜΟΒΑΚ, τις μετρήσεις, τη διαδικασία της εξέτασης, την επεξεργασία των δεδομένων και την αξιολόγηση, καθώς και με την ερμηνεία των αποτελεσμάτων. Στη συνέχεια, μαθαίνουν πώς να μεταβούν από τη διάγνωση των βασικών κινητικών δεξιοτήτων και τον εντοπισμό των αντίστοιχων ικανοτήτων των μαθητών, στον σχεδιασμό και την υλοποίηση συγκεκριμένων παρεμβάσεων με τη χρήση του υποστηρικτικού πλαισίου ΜΟΒΑΚ και των συνοδευτικών υποστηρικτικών φυλλαδίων, που είναι έτοιμα προς εφαρμογή σε συγκεκριμένες εκπαιδευτικές συνθήκες για την υποστήριξη μαθητών με πρόσθετες ανάγκες στις βασικές κινητικές δεξιότητες. Η εργαλειοθήκη κατάρτισης για εκπαιδευτικούς έχει ως σκοπό να υποστηρίξει και να διευκολύνει την εφαρμογή της Υποστηρικτικής εργαλειοθήκης για εκπαιδευτικούς (Scheuer & Heck, 2020), που βασίζεται στην έννοια και τις μετρήσεις ΜΟΒΑΚ (Herrmann, 2018).

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.

In the frame of the BMC-EU project (Basic motor competencies in Europe), a teacher training toolkit consisting of a teacher training concept with an accompanying user manual (BMC-EU intellectual output 4) was developed in order to support the implementation of the modular support toolkit on the basis of the concept of basic motor competences (BMC-EU intellectual output 3; Scheuer & Heck, 2020). The aim of this support toolkit is to be implemented mainly at the level of regular physical education lessons to initiate adaptations regarding the content and methods in physical education instruction. The teacher training toolkit contains materials to implement teacher trainings structured in a theoretical and a practical part. In a first step, teachers are familiarized with the MOBAK concept, measurement, test procedure, data procession and evaluation as well as with the interpretation of test results. In a second part, they learn how to get from the diagnosis of the students’ basic motor competencies and the strengths and weaknesses identified in the assessment to concrete interventions by using the MOBAK support framework and the accompanying supportive handouts in form of a modular support toolkit, ready to be implemented in concrete educational situations to support students with additional needs in basic motor competencies. As the teacher training toolkit aims to support and facilitate the implementation of the Modular support toolkit for teachers (Scheuer & Heck, 2020) based on the MOBAK concept and measurement (Herrmann, 2018), reference to the support toolkit and the MOBAK Test manual is given throughout this document [less ▲]

Patient-derived cancer models are essential tools for studying tumor biology and preclinical interventions. Here, we show that glioma patient-derived orthotopic xenografts (PDOXs) enable long-term propagation of patient tumors and represent clinically relevant patient avatars. We created a large collection of PDOXs from primary and recurrent gliomas with and without mutations in IDH1, which retained histopathological, genetic, epigenetic and transcriptomic features of patient tumors with no mouse-specific clonal evolution. Longitudinal PDOX models recapitulate the limited genetic evolution of gliomas observed in patient tumors following treatment. PDOX-derived standardized tumor organoid cultures enabled assessment of drug responses, which were validated in mice. PDOXs showed clinically relevant responses to Temozolomide and to targeted treatments such as EGFR and CDK4/6 inhibitors in (epi)genetically defined groups, according to MGMT promoter and EGFR/CDK status respectively. Dianhydrogalactitol, a bifunctional alkylating agent, showed promising potential against glioblastoma. Our study underlines the clinical relevance of glioma PDOX models for translational research and personalized treatment studies. [less ▲]

Nell’ambito del progetto BMC-EU (Competenze motorie di base in Europa), è stato sviluppato un manuale modulare e un allegato riguardante le competenze motorie di base e ai risultati della raccolta dei dati nella fase 1 del progetto come parte dell’analisi dei risultati nella fase 3. Lo scopo di questo allegato è quello di fungere da strumento per implementare principalmente le lezioni di educazione fisica curriculari, consentendo gli adattamenti dei contenuti e dei metodi in educazione fisica. In una prima fase, è stato sviluppato il framework per ottenere la diagnosi delle competenze motorie di base degli allievi e conoscere i punti di forza e di debolezza identificati nella valutazione attraverso interventi concreti. A tal proposito, sono stati realizzati dei documenti sotto forma di un kit e di un manuale, pronti per essere utilizzati in situazioni didattiche concrete, per sostenere gli allievi con bisogni educativi speciali nelle competenze motorie di base. Il manuale modulare include le linee guida per l'interpretazione dei risultati delle prove MOBAK (Motorische Basiskompetenzen; termine tedesco per le competenze motorie di base), il manuale modulare del MOBAK, un glossario, nonché l’allegato con i materiali per gli insegnanti di educazione fisica sotto forma di scheda descrittiva del MOBAK e schede delle attività basate sui principi di variazione del compito motorio e sull’approccio didattico orientato alla competenza.

Im Rahmen des BMC-EU-Projekts (Motorische Basiskompetenzen in Europa) wurden ein Unterstützungsrahmen und ein modulares Unterstützungs-Toolkit auf der Grundlage des Konzepts der grundlegenden motorischen Kompetenzen und der Ergebnisse der Datenerfassung in Phase 1 des Projekts als Teil des intellektuellen Outputs 3entwickelt. Ziel dieses Toolkits ist es, hauptsächlich auf der Ebene des regulären Sportunterrichts umgesetzt zu werden, um Anpassungen hinsichtlich der Inhalte und Methoden des Sportunterrichts einzuleiten. In einem ersten Schritt wurde der Unterstützungsrahmen entwickelt, um von der Diagnose der grundlegenden motorischen Kompetenzen der Schülerinnen und Schüler1 und der in der Bewertung identifizierten Stärken und Schwächen zu konkreten Interventionen zu gelangen. Basierend auf diesem Rahmen wurden unterstützende Handouts in Form eines modularen Support-Toolkits entwickelt, die in konkreten Bildungssituationen implementiert werden können, um Schüler mit zusätzlichen Anforderungen an motorische Basiskompetenzen zu unterstützen. Das modulare Support-Toolkit enthält Richtlinien für die Interpretation der Testergebnisse von MOBAK (Motorische Basiskompetenzen), das MOBAK-Unterstützungsrahmen, ein Glossar sowie das modulare Support-Toolkit mit Materialien für Sportlehrer in Form von MOBAK Aufgabenbeschreibungskarten und MOBAK-Aktivitätskarten basierend auf Variationsprinzipien und einem kompetenzorientierten Ansatz.

Στο πλαίσιο του έργου BMC-EU (Βασικές Κινητικές Δεξιότητες στην Ευρώπη) αναπτύχθηκε το πλαίσιο υποστήριξης και η υποστηρικτική εργαλειοθήκη βάση του μοντέλου των βασικών κινητικών δεξιοτήτων και των αποτελεσμάτων από τη συλλογή δεδομένων κατά τη φάση 1 του έργου, το οποίο αποτελεί μέρος της πνευματικής παραγωγής 3. Ο σκοπός της εργαλειοθήκης αυτής είναι να εφαρμοστεί στα μαθήματα φυσικής αγωγής, ώστε να προσαρμοστούν κατάλληλα τόσο το περιεχόμενο όσο και οι μέθοδοι διδασκαλίας της φυσικής αγωγής. Ως πρώτο βήμα, το υποστηρικτικό πλαίσιο αναπτύχθηκε για τη διάγνωση των βασικών κινητικών δεξιοτήτων των μαθητών, καθώς και για την αξιολόγηση των δυνατοτήτων τους, ώστε στη συνέχεια να δημιουργηθούν συγκεκριμένα παρεμβατικά προγράμματα. Με βάση το πλαίσιο αυτό, αναπτύχθηκαν υποστηρικτικά φυλλάδια με τη μορφή της υποστηρικτικής εργαλειοθήκης, έτοιμα προς εφαρμογή σε συγκεκριμένες εκπαιδευτικές συνθήκες για την υποστήριξη μαθητών με πρόσθετες ανάγκες στις βασικές κινητικές δεξιότητες. Η υποστηρικτική εργαλειοθήκη περιλαμβάνει οδηγίες για την ερμηνεία των αποτελεσμάτων του MOBAK (Motorische Basiskompetenzen; Γερμανικά για τις βασικές κινητικές δεξιότητες), το πλαίσιο υποστήριξης ΜΟΒΑΚ, ένα γλωσσάρι, καθώς και την υποστηρικτική εργαλειοθήκη με εργαλεία για καθηγητές φυσικής αγωγής υπό τη μορφή καρτών περιγραφής διαδικασιών και καρτών δραστηριοτήτων ΜΟΒΑΚ, βασισμένα στις αρχές της παραλλαγής των δραστηριοτήτων και σε μία προσέγγιση προσανατολισμένη στις δεξιότητες.

Im Rahmen dieser Newsletter wird analysiert, in welchem Maße Vorgesetzte in Luxemburg einen transformationalen Führungsstil umsetzen. Vorgesetzte, die einen transformationalen Führungsstil ausüben, werden von ihren Mitarbeitern als fairer und unterstützender wahrgenommen. Insgesamt geht dieser Führungsstil einher mit als vorteilhafter erlebten Arbeitsbedingungen sowie einem erhöhten Well-Being der Mitarbeiter. Arbeitnehmer berichten dabei im Vergleich zu Arbeitnehmerinnen tendenziell über das Erleben eines höheren Ausmaßes an transformationalem Führungsstil ihres Vorgesetzten. Differenziert nach Beruf berichten vor allem Manager über ein überdurchschnittliches Ausmaß an transformationaler Führung ihres Vorgesetzten. [less ▲]

In the frame of the BMC-EU project (Basic motor competencies in Europe), a support framework and a modular support toolkit on the basis of the concept of basic motor competences and the results of the data collection in phase 1 of the project was developed as part of intellectual output 3. The aim of this toolkit is to be implemented mainly at the level of regular physical education lessons to initiate adaptations regarding the content and methods in physical education instruction. In a first step, the support framework was developed for getting from the diagnosis of the students’ basic motor competencies and the strengths and weaknesses identified in the assessment to concrete interventions. Based on this framework, supportive handouts in form of a modular support toolkit were developed, ready to be implemented in concrete educational situations to support students with additional needs in basic motor competencies. The modular support toolkit includes guidelines for the interpretation of MOBAK (Motorische Basiskompetenzen; German for basic motor competencies) test results, the MOBAK support framework, a glossary, as well as the modular support toolkit with materials for physical education teachers in the form of MOBAK task description cards and MOBAK activity cards based on principles of variation and on a competence-oriented approach.
