[more ▼] National parliaments tend to delegate a range of tasks related to EU affairs scrutiny to their administrations. However, there is considerable variation in the extent to which national parliaments invest in EU affairs staff. This raises two questions: what is the source of this diversity, and what is its impact on the EU affairs scrutiny of national parliaments? This paper argues that greater investments in EU affairs staff are associated with public Euroscepticism, large parliaments and parliaments with strong scrutiny powers. A large EU staff is, in turn, associated with parliaments that are relatively active in EU affairs scrutiny. This is particularly true for the 15 EU member states that joined before 2004.

[more ▼] We study the geometry of the foliation by constant Gaussian curvature surfaces (S_k)_k of a hyperbolic end, and how it relates to the structures of its boundary at infinity and of its pleated boundary. First, we show that the Thurston and the Schwarzian parametrizations are the limits of two families of parametrizations of the space of hyperbolic ends, defined by Labourie in 1992 in terms of the geometry of the leaves S_k. We give a new description of the renormalized volume using the constant curvature foliation. We prove a generalization of McMullen's Kleinian reciprocity theorem, which replaces the role of the Schwarzian parametrization with Labourie's parametrizations. Finally, we describe the constant curvature foliation of a hyperbolic end as the integral curve of a time-dependent Hamiltonian vector field on the cotangent space to Teichmüller space, in analogy to the Moncrief flow for constant mean curvature foliations in Lorenzian space-times.

[more ▼] It is no exaggeration to say that since the introduction of Bitcoin, blockchains have become a disruptive technology that has shaken the world. However, the rising popularity of the paradigm has led to a flurry of proposals addressing variations and/or trying to solve problems stemming from the initial specification. This added considerable complexity to the current blockchain ecosystems, amplified by the absence of detail in many accompanying blockchain whitepapers. Through this paper, we set out to explain blockchains in a simple way, taming that complexity through the deconstruction of the blockchain into three simple, critical components common to all known systems: membership selection, consensus mechanism and structure. We propose an evaluation framework with insight into system models, desired properties and analysis criteria, using the decoupled components as criteria. We use this framework to provide clear and intuitive overviews of the design principles behind the analyzed systems and the properties achieved. We hope our effort will help clarifying the current state of blockchain proposals and provide directions to the analysis of future proposals.

[more ▼] We prove global results about actions of cocompact lattices in higher-rank simple Lie groups on closed manifolds endowed with either a projective class of connections or a conformal class of pseudo-Riemannian metrics of signature (p,q), with min(p,q)>1. In the continuity of a recent article, provided that such a structure is locally equivalent to its model X, the main question treated here is the completeness of the associated (G,X)-structure. The similarities between the model spaces of non-Lorentzian conformal geometry and projective geometry make that lots of arguments are valid for both cases, and we expose the proofs in parallel. The conclusion is that in both cases, when the real-rank is maximal, the manifold is globally equivalent to either the model space X or its double cover.

[more ▼] Let $X$ be a nonempty set. Denote by $\mathcal{F}^n_k$ the class of associative operations $F\colon X^n\to X$ satisfying the condition $F(x_1,\ldots,x_n)\in\{x_1,\ldots,x_n\}$ whenever at least $k$ of the elements $x_1,\ldots,x_n$ are equal to each other. The elements of $\mathcal{F}^n_1$ are said to be quasitrivial and those of $\mathcal{F}^n_n$ are said to be idempotent. We show that $\mathcal{F}^n_1=\cdots =\mathcal{F}^n_{n-2}\varsubsetneq\mathcal{F}^n_{n-1}\varsubsetneq\mathcal{F}^n_n$. The class $\mathcal{F}^n_1$ was recently characterized by Couceiro and Devillet \cite{CouDev}, who showed that its elements are reducible to binary associative operations. However, some elements of $\mathcal{F}^n_n$ are not reducible. In this paper, we characterize the class $\mathcal{F}^n_{n-1}\setminus\mathcal{F}^n_1$ and show that its elements are reducible. In particular, we show that each of these elements is an extension of an $n$-ary Abelian group operation whose exponent divides $n-1$.

[more ▼] In this paper we investigate the effect of local interaction in a simple urban economics model. Agents interact with others if and only if their interaction benefit outweights their travel cost and therefore meet others only within finite geographic windows. We show that two or more cites may co-exist at the equilibrium provided that they are sufficiently distant. For any interaction surplus function, there exists a unique spatial equilibrium on not too large city supports. The population density within a city is determined by a second order advance-delay differential equation, whose solutions are fully characterized for linear interaction surplus functions. Numerical analyses show that more localized interactions yield flatter population density and land rents over larger extents of the city support. They do not give support to the idea that multiple subcenters can be caused by small and finite geographic windows of interaction.

[more ▼] This country report sought to explore the border as a site of control and the ways in which it interferes with migrants’ (asylum seekers, refugees and rejected asylum seekers) trajectories before, upon and after arrival in Luxembourg. To this end, it explored, through qualitative interviews with a total of 29 state and civil society actors and migrants, as well as ethnographic observation at Findel airport, Luxembourg’s only external border, the multiple conceptualisations and experiences of borders. It has identified that the suppression of internal controls within the Schengen area has been accompanied by a surge of controls within the member states, either at the stage of lodging an asylum claim, or at the street level, where migrants can be stopped and searched by police officers. Furthermore, the data showed that the migrants interviewed not only did they experience bordering practices during their interactions with public actors, but they were also subject to bordering during their interactions with private actors from the housing and employment market. The principal finding of this research with regards to the interplay between borders and the mobility of migrants is that cross-border mobility is commonplace, the migrants’ mobility practices reflecting the movements of the local population. As such, borders do not represent efficient mechanisms of control which can prevent migrants’ mobility trajectories.

[more ▼] This comparative report investigates the ways in which the mobility of applicants for international protection, beneficiaries of international protection and irregular migrants intersect with the borders encountered during their trajectories before, during and after their arrival in six EU countries (Greece, Hungary, Germany, Luxembourg, France and Spain) and Turkey. After defining the concept of borders, this study contextualises the securitisation of EU external and internal borders, and it provides some background information on the CEAS and the Dublin Regulation, which are central to this research. Moreover, it engages with the legislative framework in place in the field of asylum in the seven countries on which this report draws. Based on qualitative interviews with a total of 96 asylum seekers, refugees and irregular migrants, as well as 94 state and non-state actors and ethnographic observation, the empirical part of the study explored the following aspects: experiences and conceptualisations of borders; mobility patterns and trajectories; the interplay between the Schengen zone and the Dublin system; the shortcomings of CEAS; as well as policies and experiences in the fields of housing and employment. The main finding of this comparative report is that while territorial borders cannot always impede human mobility, they are recreated within countries as administrative borders, which can encourage secondary movements.

The ... [more ▼] This country report investigates the ways in which the border as a site of control interferes with asylum seekers’ and refugees’ mobility trajectories before, upon and after arrival in France. The interplay between borders and mobility plays a key role in the Common European Asylum System, the Schengen area and the Dublin regulation, which all have been affected by the 2015 so-called migration crisis. Based on in-depth qualitative interviews with thirteen migrants and ten institutional actors in the city of Metz, the overarching finding indicates that migrants’ movements evolve from geographical trajectories in order to reach a country of destination, to administrative trajectories, in order to become regularised in the host country. Furthermore, while physical borders have interfered with some informants’ migratory journeys, they have done so only by changing their trajectories, and, at times, the initial country of destination. Thus, they did not deter the migrants from reaching a safe country of destination. Once in Metz, the migrants become subject to administrative borders performed by state agents, such as the Préfecture and the French Agency for Immigration and Integration (OFII), as well as by private actors from the employment market.

[more ▼] Let G be a connected, reductive, complex affine algebraic group, and let Xr denote the moduli space of G-valued representations of a rank r free group. We first characterize the singularities in Xr resolving conjectures of Florentino-Lawton. In particular, we compute the codimension of the orbifold singular locus using facts about Borel-de Siebenthal groups. We then use this codimension to calculate some higher homotopy groups of the smooth locus of Xr, proving conjectures of Florentino-Lawton-Ramras. Lastly, using the earlier analysis of Borel-de Siebenthal groups, we prove a conjecture of Sikora about CI Lie groups.

[more ▼] We study a notion of "width" for Jordan curves in CP1, paying special attention to the class of quasicircles. The width of a Jordan curve is defined in terms of the geometry of its convex hull in hyperbolic three-space. A similar invariant in the setting of anti de Sitter geometry was used by Bonsante-Schlenker to characterize quasicircles amongst a larger class of Jordan curves in the boundary of anti de Sitter space. By contrast to the AdS setting, we show that there are Jordan curves of bounded width which fail to be quasicircles. However, we show that Jordan curves with small width are quasicircles.

The case concerns the financing by the bank of a biomass energy generating project in Northern Spain – Galicia -, of the cost of 60 million euros, followed by the bank’s refusal to refine its decision to finance the aforementioned investment, regardless the applicant’s request for an internal review of this decision on April 2018. The applicant bases the request for an internal review on alleged ‘errors in the assessment of the financing combined with the provision of minimal information regarding the funding decision’. The main claim brought by the applicant involves the annulment of EIB’s refusal to conduct an internal review and subject its decision to scrutiny, as requested under Article 10 of the Aarhus Regulation (hereafter Regulation), bringing into discussion implementation issues of both International and European law.

[more ▼] The regulation of banking activities present policymakers with a conundrum: while essential for a healthy and growing economy, they also present important risks of crises that affect all citizens. Prudential regulation is intended to contain the risks while enabling the socially beneficial functions of banks, but the shadow of financial interests influence hangs over the regulatory process. Assessing the reality and extent of this influence, this paper argues, requires first to acquire asound understanding of the social costs and benefits of banking, and the capacity of regulation to promote social welfare. This paper then offers the reader a review of the main issues covered in the literature and suggests some lessons for the study of financial interest groups.

[more ▼] Inference of the structural and functional consequences of amino acid-altering missense variants is challenging and not yet scalable. Clinical and research applications of the colossal number of identified missense variants is thus limited. Here we describe the aggregation and analysis of large-scale genomic variation and structural biology data for 1,330 disease-associated genes. Comparing the burden of 40 structural, physicochemical, and functional protein features of altered amino acids with 3-dimensional coordinates, we found 18 and 14 features that are associated with pathogenic and population missense variants, respectively. Separate analyses of variants from 24 protein functional classes revealed novel function-dependent vulnerable features. We then devised a quantitative spectrum, identifying variants with higher pathogenic variant-associated features. Finally, we developed a web resource (MISCAST; http://miscast.broadinstitute.org/) for interactive analysis of variants on linear and tertiary protein structures. The biological impact of missense variants available through the webtool will assist researchers in hypothesizing variant pathogenicity and disease trajectories.

[more ▼] This paper investigates whether a higher level of long-term credit provision affects the growth of small and young firms. Firm-level data from more than 20,000 firms in 62 countries are combined with a new hand-collected database on short-term and long-term credit provided to the private sector. Using a difference-in-difference framework, our results indicate that, contrary to short-term credit, long-term credit does not stimulate growth of small and young firms. This finding is, at least partially, explained by the differential impact of short-term and long-term credit provision on small and young firms’ access to credit. While the provision of short-term credit alleviates credit constraints faced by small and young firms, a larger provision of longterm bank loans has an opposite impact. Our findings are in line with the hypothesis that an increase of long-term credit provision reflects a lender’s choice to provide more financing to existing clients (intensive margin) to the detriment of firms without previous access to finance (extensive margin).

[more ▼] Mitochondria as the main energy suppliers of eukaryotic cells are highly dynamic organelles that fuse, divide and are transported along the cytoskeleton to ensure cellular energy homeostasis. While these processes are well established, substantial evidence indicates that the internal structure is also highly variable in dependence on metabolic conditions. However, a quantitative mechanistic understanding of how mitochondrial morphology affects energetic states is still elusive. To address this question, we here present an agent-based dynamic model using three-dimensional morphologies from electron microscopy tomography which considers the molecular dynamics of the main ATP production components. We apply our modeling approach to mitochondria at the synapse which is the largest energy consumer within the brain. Interestingly, comparing the spatiotemporal simulations with a corresponding space-independent approach, we find minor space dependence when the system relaxes toward equilibrium but a qualitative difference in fluctuating environments. These results suggest that internal mitochondrial morphology is not only optimized for ATP production but also provides a mechanism for energy buffering and may represent a mechanism for cellular robustness.

[more ▼] Missense variant interpretation is challenging. Essential regions for protein function are conserved among gene family members, and genetic variants within these regions are potentially more likely to confer risk to disease. Here, we generated 2,871 gene family protein sequence alignments involving 9,990 genes and performed missense variant burden analyses to identify novel essential protein regions. We mapped 2,219,811 variants from the general population into these alignments and compared their distribution with 65,034 missense variants from patients. With this gene family approach, we identified 398 regions enriched for patient variants spanning 33,887 amino acids in 1,058 genes. As a comparison, testing the same genes individually we identified less patient variant enriched regions involving only 2,167 amino acids and 180 genes. Next, we selected de novo variants from 6,753 patients with neurodevelopmental disorders and 1,911 unaffected siblings, and observed a 5.56-fold enrichment of patient variants in our identified regions (95% C.I. =2.76-Inf, p-value = 6.66×10−8). Using an independent ClinVar variant set, we found missense variants inside the identified regions are 111-fold more likely to be classified as pathogenic in comparison to benign classification (OR = 111.48, 95% C.I = 68.09-195.58, p-value < 2.2e−16). All patient variant enriched regions identified (PERs) are available online through a user-friendly platform for interactive data mining, visualization and download at http://per.broadinstitute.org. In summary, our gene family burden analysis approach identified novel patient variant enriched regions in protein sequences. This annotation can empower variant interpretation.

For ... [more ▼] We examine the effects of monetary policy on household self-assessed financial stress and durable consumption using panel data from eighteen annual waves of the British Household Panel Survey. For identification, we exploit random variation in household exposure to interest rates generated by the random timing of household interview dates with respect to policy rate changes. After accounting for household and month-year-of- interview fixed effects, we uncover significant heterogeneities in the way monetary policy affects household groups that differ in housing and saving status. In particular, an increase in the interest rate induces financial stress among mortgagors and renters, while it lessens financial stress of savers. We find symmetric effects on durable consumption, mainly driven by mortgagors with high debt burden or limited access to liquidity and younger renters who are prospective home buyers.

Da die Erhebung 2018 als Mixed-Mode-Design – telefonische als auch Online-Befragung – durchgeführt wurde, wird auch analysiert, ob Stichprobenunterschiede zwischen den beiden Erhebungsmodi auftreten. Außerdem wird geklärt, ob es hinsichtlich demographischer Eigenschaften der Befragten, hinsichtlich der QoW-Skalen oder hinsichtlich verschiedener Well-Being-Maße zu systematischen Ausfällen seit der letzten Welle gekommen ist. Dann werden die Items der QoW- und Well-Being-Skalen auf fehlende Werte untersucht und es erfolgt eine Beschreibung der Items mittels verteilungsbeschreibender Maßzahlen und Balkendiagramme. In einem nächsten Schritt werden die Skalen mittels verschiedener Reliabilitätsstatistiken (Cronbach’s Alpha, Korrelationsanalysen der Items) sowie Koeffizienten zur Beschreibung der Skalenverteilung überprüft. Außerdem werden die Zusammenhänge der Skalen mittels Korrelationsanalysen überprüft. Im Anschluss daran wird die unterstellte Faktorenstruktur mittels konfirmatorischer Faktoren-analysen getestet. Die QoW-Skalen werden außerdem auf verschiedene Well-Being-Skalen regressiert, um deren Relevanz für den QoW-Index zu prüfen. Ebenso werden einige Längsschnitt-Regressionsanalysen durchgeführt, um zu überprüfen ob einige Arbeitsbedingungen längerfristige Effekte auf das Well-Being der Arbeitnehmer aufweisen. Die QoW-Befragung 2018 hat außerdem das Schwerpunktthema „Work-Life-Balance“ behandelt. Die Güte der Skalen zu diesem Thema wird ebenfalls geprüft. Im Anschluss werden dann Korrelationen mit den QoW- und Well-Being-Skalen berechnet. Abschließend wird das gesamte Erhebungsinstrument zusammenfassend diskutiert und Emp-fehlungen bezüglich zukünftiger Befragungen gegeben.

[more ▼] Cross-border workers form a little-known but numerous population in Switzerland. Beyond clichés, this contribution brings together the main characteristics of this population based on official statistics and the latest research. The introduction of the Freedom of Movement Agreement did not change the growth trend of the population that remains to live and work in proximity of the border, mostly in France and near-Switzerland agglomerations. Conversely, the occupational areas and levels have diversified. Generally, cross-border workers have no negative influence on the labour market, except on salary level in some economic sectors in Ticino. The initiation of the “priority to Swiss residents” will not change the situation, which relates above all to the economic evolution.

[more ▼] This article questions the impacts of cross-border worker mobility on the economic and social devel-opment of their place of residence. We hypothesize that cross-border mobility produces resources for the worker, the enterprise and the territory, but it can also be a source of constraints. After a geo-graphical framework of the study, this article analyses the main positive territorial impacts of cross-border mobility. It shows that they contribute to the territorial dynamism of these border regions by attracting new sociological profiles of workers, by revitalizing rural territories (through housing), by limiting the increase of local unemployment and by encouraging a new form of in-place economy. Fi-nally, the paper also shows how such mobility can impede the own development of these border terri-tories, such as via a deeper local social stratification and a lack of highly qualified manpower.

[more ▼] For an odd prime p, we study the image of a continuous 2-dimensional (pseudo)representation rho of a profi nite group with coe cients in a local pro-p domain A. Under mild conditions, Bella che has proved that the image of rho contains a nontrivial congruence subgroup of SL2(B) for a certain subring B of A. We prove that the ring B can be slightly enlarged and then described in terms of the conjugate self-twists of rho, symmetries that naturally constrain its image; hence this new B is optimal. We use this result to recover, and in some cases improve, the known large-image results for Galois representations arising from elliptic and Hilbert modular forms due to Serre, Ribet and Momose, and Nekov a r, and p-adic Hida or Coleman families of elliptic modular forms due to Hida, Lang, and Conti-Iovita-Tilouine.

[more ▼] Human stem cell-derived organoids have great potential for modelling physiological and pathological processes. They recapitulate in vitro the organisation and function of a respective organ or part of an organ. Human midbrain organoids (hMOs) have been described to contain midbrain-specific dopaminergic neurons that release the neurotransmitter dopamine. However, the human midbrain contains also additional neuronal cell types, which are functionally interacting with each other. Here, we analysed hMOs at high-resolution by means of single-cell RNA-sequencing (scRNA-seq), imaging and electrophysiology to unravel cell heterogeneity. Our findings demonstrate that hMOs show essential neuronal functional properties as spontaneous electrophysiological activity of different neuronal subtypes, including dopaminergic, GABAergic, and glutamatergic neurons. Recapitulating these in vivo features makes hMOs an excellent tool for in vitro disease phenotyping and drug discovery. [less ▲] Detailed reference viewed: 220 (45 UL)Scalable Viewing.

[more ▼] In the Grand Duchy of Luxembourg, the residential building sector is a major energy consumer and greenhouse gases emitter that is considered key in achieving the country's climate goals. The purpose of this paper is to assess the effectiveness of the most important policy instruments in achieving savings in the final energy consumption and direct CO2 emissions of Luxembourgish households. Our study is based on the LuxHEI model, which is an enhanced and upgraded version of the well-known French simulation model Res-IRF. This variant has been adjusted to the particular problems of a small country with growing economy and a quickly increasing population. The LuxHEI model goes beyond standard energy-economy models by incorporating global warming as a decision-making factor. The model outcomes reveal that total environmental and economic effectiveness increases if energy policy tools are applied concurrently. In 2060, and compared to the no-policy baseline scenario, the most aspirational policy mix enables energy savings of 42% and an emission mitigation of 60%. From our results we can draw the following policy implications: for a significant improvement of the sector's energy efficiency and sufficiency, (1) the implementation of a remediation duty for existing buildings and (2) the tightening of the performance standards for new constructions, (3) combined with a national carbon tax, are crucial.

[more ▼] Quasifuchsian hyperbolic manifolds, or more generally convex co-compact hyperbolic manifolds, have infinite volume, but they have a well-defined ``renormalized'' volume. We outline some relations between this renormalized volume and the volume, or more precisely the ``dual volume'', of the convex core. On one hand, there are striking similarities between them, for instance in their variational formulas. On the other, object related to them tend to be within bounded distance. Those analogies and proximities lead to several questions. Both the renormalized volume and the dual volume can be used for instance to bound the volume of the convex core in terms of the Weil-Petersson distance between the conformal metrics at infinity.

Au lendemain de la Première Guerre mondiale, alors que le parc automobile et les flux touristiques croissent de façon vertigineuse, les courses automobiles se multiplient. Un championnat d’Europe est organisé en 1925 par la Commission sportive internationale de l’Association internationale des automobile-clubs reconnus (AIACR) qui s’appuie sur des initiatives locales. Pour les organisateurs locaux de courses, inscrire son circuit dans le calendrier du championnat d’Europe devient un enjeu majeur. Soutenus par les commerçants, industriels et édiles politiques locaux, les organisateurs saisissent l’occasion de la course pour faire de la publicité et stimuler l’économie. Partout en Europe, des acteurs locaux se mobilisent en ce sens pour tirer profit et prestige des circulations plurielles qu’engendre le sport automobile européen.

[more ▼] The rank n swapping algebra is a Poisson algebra defined on the set of ordered pairs of points of the circle using linking numbers, whose geometric model is given by a certain subspace of (K^n×K^{n∗})^r/GL(n,K). For any ideal triangulation of D_k---a disk with k points on its boundary, using determinants, we find an injective Poisson algebra homomorphism from the fraction algebra generated by the Fock--Goncharov coordinates for X_{PGL_n,D_k} to the rank n swapping multifraction algebra for r=k⋅(n−1) with respect to the (Atiyah--Bott--)Goldman Poisson bracket and the swapping bracket. This is the building block of the general surface case. Two such injective Poisson algebra homomorphisms related to two ideal triangulations T and T′ are compatible with each other under the flips.

[more ▼] Celebrated work of Alexandrov and Pogorelov determines exactly which metrics on the sphere are induced on the boundary of a compact convex subset of hyperbolic three-space. As a step toward a generalization for unbounded convex subsets, we consider convex regions of hyperbolic three-space bounded by two properly embedded disks which meet at infinity along a Jordan curve in the ideal boundary. In this setting, it is natural to augment the notion of induced metric on the boundary of the convex set to include a gluing map at infinity which records how the asymptotic geometry of the two surfaces compares near points of the limiting Jordan curve. Restricting further to the case in which the induced metrics on the two bounding surfaces have constant curvature Kâˆˆ[âˆ’1,0) and the Jordan curve at infinity is a quasicircle, the gluing map is naturally a quasisymmetric homeomorphism of the circle. The main result is that for each value of K, every quasisymmetric map is achieved as the gluing map at infinity along some quasicircle. We also prove analogous results in the setting of three-dimensional anti de Sitter geometry. Our results may be viewed as universal versions of the conjectures of Thurston and Mess about prescribing the induced metric on the boundary of the convex core of quasifuchsian hyperbolic manifolds and globally hyperbolic anti de Sitter spacetimes.

Preventing and fighting ML and the financing of terrorism ... [more ▼] Financial information can play a key role in tackling Money Laundering (ML), Terrorist Financing (TF) and combatting serious crime more generally. Preventing and fighting ML and the financing of terrorism were top priorities of the European Agenda on Security, which might explain the fast developments regarding the regulation of Anti-Money Laundering (AML) and Counter Terrorism Financing (CTF). During the past years, the European Commission (Commission) proposed several legal texts to reform the current AML framework and to facilitate timely law enforcement (LE) access to financial data for the prevention, detection, investigation and prosecution of serious crime. The line between administrative sanctions and criminal law measures seems to become increasingly blurred, as the latest proposals are no longer based on an internal market provision, but on police and judicial cooperation legal bases. Financial Intelligence Units (FIUs) play a crucial role in analysing and exchanging information concerning suspicious transactions, serving as intermediaries between the private sector and Law Enforcement Authorities (LEAs). Because of the international nature of financial crime, cooperation between FIUs is of paramount importance. Yet, due to different organizational settings in the EU Member States, FIUs are not always able to exchange data effectively, which leads to information gaps. One of the reasons why the data exchange between FIUs is impeded are data protection rules that apply differently depending on the organizational structure of the FIUs in the 28 Member States. Whereas some FIUs must adhere to the stricter data protection rules under the General Data Protection Regulation (GDPR), others may exchange data more flexibly within the scope of the data protection Directive for police and criminal justice authorities (LED). Therefore, the counter-argument to granting broader LE-access rights to financial data by LEAs could be to enable a more effective exchange of data between FIUs. This article argues that FIUs should be able to process personal data within the scope of the LED, in order to have more flexibility to receive, analyse and exchange data: On the one hand, the LED provides sufficiently high data protection standards and adequate safeguards for data subjects while allowing FIUs to carry out their tasks effectively under harmonized rules. On the other hand, this would be an argument to strengthening the role of FIUs as neutral intermediaries instead of granting additional access to personal data by LEAs.

Using these regular functions, we obtain McShane identities general rank positive surface group representations with loxodromic boundary monodromy and (non-strict) McShane-type inequalities for general rank positive representations with unipotent boundary monodromy. Our identities are expressed in terms of projective invariants, and we study these invariants: we establish boundedness and Fuchsian rigidity results for triple ratios. Moreover, we obtain McShane identities for finite-area cusped convex real projective surfaces by generalizing the Birman--Series geodesic scarcity theorem. We apply our identities to derive the simple spectral discreteness of unipotent bordered positive representations, collar lemmas, and generalizations of the Thurston metric.

[more ▼] We investigate conformal actions of cocompact lattices in higher-rank simple Lie groups on compact pseudo-Riemannian manifolds. Our main result gives a general bound on the real-rank of the lattice, which was already known for the action of the full Lie group ([33]). When the real-rank is maximal, we prove that the manifold is conformally flat. This indicates that a global conclusion similar to that of [1] and [17] in the case of a Lie group action might be obtained. We also give better estimates for actions of cocompact lattices in exceptional groups. Our work is strongly inspired by the recent breakthrough of Brown, Fisher and Hurtado on Zimmer’s conjecture [7].

[more ▼] This paper has two main objectives. First, it attempts to distinguish the effects of household and enterprise credit on economic growth for a large sample of developing and developed countries. Second, it investigates the channels through which household credit affects economic growth. To do so, a new database covering 143 countries over the period 1995-2014 is employed. Econometric results show that household credit has a negative effect on growth, while business credit has a positive, albeit non significant, impact on growth. The literature provide two possible explanations to justify the negative effect of household credit. On the one hand, household credit expansion can induce more financial fragility. On the other hand, the negative impact of household credit could be explained by its effect on saving behaviors. Results provide some evidence indicating that the negative effect of household credit is more driven by the latter than the former.

These observations are based on selected findings from three recent empirical studies of the study region, which have been linked to each other as well as socio-culturally and socioeconomically mapped in order to carve out the spatial organiza-tion, the motives and other contextual factors of cross-border everyday practices in the Greater Region SaarLorLux. This approach allows reconstructing mobility flows and spatial emphases in the context of everyday practices and gives insights into the nature of cross-border living realities in the Greater Region SaarLorLux.

[more ▼] In an era of mass migration, social scientists, populist parties and social movements raise concerns over the future of immigration-destination societies. What impacts does this have on policy and social solidarity? Comparative cross-national research, relying mostly on secondary data, has findings in different directions. There is a threat of selective model reporting and lack of replicability. The heterogeneity of countries obscures attempts to clearly define data-generating models. P-hacking and HARKing lurk among standard research practices in this area.This project employs crowdsourcing to address these issues. It draws on replication, deliberation, meta-analysis and harnessing the power of many minds at once. The Crowdsourced Replication Initiative carries two main goals, (a) to better investigate the linkage between immigration and social policy preferences across countries, and (b) to develop crowdsourcing as a social science method. The Executive Report provides short reviews of the area of social policy preferences and immigration, and the methods and impetus behind crowdsourcing plus a description of the entire project. Three main areas of findings will appear in three papers, that are registered as PAPs or in process.

In the case of one-dimensional persistence, our definition agrees with the usual one showing that the observable category and the category of γ-sheaves are equivalent. We also establish isometry theorems between the category of persistent modules and γ-sheaves both endowed with their interleaving distance. Finally, we compare the interleaving and convolution distances.

[more ▼] S-boxes are the only source of non-linearity in many symmetric primitives. While they are often defined as being functions operating on a small space, some recent designs propose the use of much larger ones (e.g., 32 bits). In this context, an S-box is then defined as a subfunction whose cryptographic properties can be estimated precisely. In this paper, we present a 64-bit ARX-based S-box called Alzette, which can be evaluated in constant time using only 12 instructions on modern CPUs. Its parallel application can also leverage vector (SIMD) instructions. One iteration of Alzette has differential and linear properties comparable to those of the AES S-box, while two iterations are at least as secure as the AES super S-box. Since the state size is much larger than the typical 4 or 8 bits, the study of the relevant cryptographic properties of Alzette is not trivial.

[more ▼] We develop a decomposition of distributional change by factor components to quantify how changes in the association between sources of income and changes in their marginal distributions contribute to the change in the distribution of household incomes over time. The two components are further broken down to isolate the contribution of specific income sources. Application to the change in the distribution of household incomes in Luxembourg between 2004 and 2013 reveals contrasted results: increased association between spouse earnings, public transfers, and taxes depressed the income share of poor households while changes in marginal distributions increased incomes in the upper half of the distribution.

[more ▼] The Legendre PRF relies on the conjectured pseudorandomness properties of the Legendre symbol with a hidden shift. Originally proposed as a PRG by Damgård at CRYPTO 1988, it was recently suggested as an efficient PRF for multiparty computation purposes by Grassi et al. at CCS 2016. Moreover, the Legendre PRF is being considered for usage in the Ethereum 2.0 blockchain. This paper improves previous attacks on the Legendre PRF and its higher-degree variant due to Khovratovich by reducing the time complexity from O(plogp/M) to O(plog^2p/M2) Legendre symbol evaluations when M≤p√4 queries are available. The practical relevance of our improved attack is demonstrated by breaking two concrete instances of the PRF proposed by the Ethereum foundation. Furthermore, we generalize our attack in a nontrivial way to the higher-degree variant of the Legendre PRF and we point out a large class of weak keys for this construction. Lastly, we provide the first security analysis of two additional generalizations of the Legendre PRF originally proposed by Damgård in the PRG setting, namely the Jacobi PRF and the power residue PRF.

[more ▼] This paper discusses a trade model with many countries, many goods produced in multiple quality versions, and non-homothetic preferences. It embeds in the same model a series of results that have been empirically confirmed: high-income countries specialize in the production of high-quality goods and trade more of those. Richer countries purchase more high-quality varieties. They import more high-quality products from the most productive exporters. The paper then studies the impact of productivity and population changes on the quality composition of exports. It finally explains why countries import higher quality goods from more distant countries.

This paper discusses the socially optimal sizes and locations of urban green areas within a city and their decentralized allocation through land markets. The main result is that the share of land dedicated to urban green areas is a concave function of the distance to the city center. This result is confirmed by the empirical study of urban structures in the 305 largest EU cities. The importance of urban green areas is finally assessed by a counterfactual analysis, where 50% of urban green areas are removed in each city.

[more ▼] Chemotaxis, the movement of an organism in response to a chemical stimulus, is a typical feature of many microbiological systems. In particular, the social amoeba Disctyostelium discoideum is widely used as a model organism, but it is not still clear how it behaves in heterogeneous environments. A few models focused on mechanical features have already addressed the question; however, we propose that phenomenological models focusing on the dynamics may provide new meaningful data. Consequently, by means of a specific Multi-agent system model, we studied the dynamical features emerging from complex social interactions among individuals belonging to amoeboids colonies. After defining an appropriate metric to perform meaningful measurements, we found that: a) obstacles play the role of local topological perturbation, as they alter the flux of chemical signals; b) that obstacle that physically block the cellular motion as well as the chemicals elicit dynamical evolutions that are not statistically distinguishable from the case where obstacles that do not interfere physically with said motion; c) that fluctuations of the dynamics can lead to better exploration of the physical space, thus preventing multiple stable aggregates. From previous results, we may speculate about the fact that chemotactic cells, in many cases, can avoid obstacles by simply following the altered chemical gradient: social interactions seem to be sufficient to guarantee the aggregation of the whole colony past numerous obstacles. It is then unlikely that cells have developed special mechanisms to cope with the presence of topological perturbation sources. Nevertheless, we suggest that further studies can provide better understanding and that, in order to gain deeper knowledge, mechanical models should be coupled with phenomenological, system-oriented ones.

[more ▼] Let (S,h) be a closed hyperbolic surface and M be a quasi-Fuchsian 3-manifold. We consider incompressible maps from S to M that are critical points of an energy functional F which is homogeneous of degree 1. These ``minimizing'' maps are solutions of a non-linear elliptic equation, and reminiscent of harmonic maps -- but when the target is Fuchsian, minimizing maps are minimal Lagrangian diffeomorphisms to the totally geodesic surface in M. We prove the uniqueness of smooth minimizing maps from (S,h) to M in a given homotopy class. When (S,h) is fixed, smooth minimizing maps from (S,h) are described by a simple holomorphic data on S: a complex self-adjoint Codazzi tensor of determinant 1. The space of admissible data is smooth and naturally equipped with a complex structure, for which the monodromy map taking a data to the holonomy representation of the image is holomorphic. Minimizing maps are in this way reminiscent of shear-bend coordinates, with the complexification of F analoguous to the complex length.

[more ▼] Prettner (2019) studies the implications of automation for economic growth and the labor share in a variant of the Solow-Swan model. The aggregate production function allows for two types of capital, traditional and automation capital. Traditional capital and labor are imperfect substitutes whereas automation capital and labor are perfect substitutes. In this paper, we point to a flaw in Prettner’s analysis that invalidates his main analytical and computational findings. In contrast to Prettner, we argue that both kinds of capital are perfect substitutes as stores of value, and, therefore, must earn the same rate of return in equilibrium. Our computational analysis shows that the model dramatically overestimates the actual decline in the US labor share over the last 50 years.

[more ▼] This paper develops a new method to model the household disposable income distribution and decompose changes in this distribution (or functionals such as inequality measures) over time. It integrates both a micro-econometric and microsimulation approaches, combining a flexible parametric modelling of the distribution of market income with the EUROMOD microsimulation model to simulate the value of taxes and benefits. The method allows for the quantification of the contributions of four main factors to changes in the disposable income distribution between any two years: (i) labour market structure; (ii) returns; (iii) demographic composition; and (iv) tax-benefit system. We apply this new framework to the study of changes in the income distribution in Portugal between 2007 and 2013, accounting for the distributional effects of the 2007-2008 crisis and aftermath policies, in particular the Economic Adjustment Program (EAP). Results show that these effects were substantial and reflected markedly different developments over two periods: 2007-2009, when stimulus packages determined important income gains for the bottom of the distribution and a decrease in income inequality; 2010-2013, when the crisis and austerity measures took a toll on the incomes of Portuguese households, particularly those at the bottom and top of the distribution, leading to an increase in income inequality.

[more ▼] The right to an effective judicial remedy is an essential element of realising the rule of law. It is the fundamental right granting individuals the possibility to request independent review of compliance with the legal provisions. The genius of protecting as an individual fundamental right this structural notion of independent judicial review, has much contributed to the prominence and the protection of judicial accountability and effective enforcement of EU law. Yet, this critical commentary on the right to an effective remedy shows that the case law of the CJEU has predominantly aimed at ensuring Member State compliance with the right to an effective remedy. When it comes to reviewing EU law provisions against this right, the general considerations of ensuring effective judicial remedies are a lot less pressing, and accordingly, the CJEU has decided to be less stringent in its application of the right. Such case law of the CJEU has left gaps in protection. The commentary ends with the observations that additional problems for the enforcement of the right to an effective remedy arise from the often-composite nature of procedures, linking one or several Member State bodies with European institutions and bodies in one single procedure.

[more ▼] Malfunctions of voltage-gated sodium and calcium channels (SCN and CACNA1 genes) have been associated with severe neurologic, psychiatric, cardiac and other diseases. Altered channel activity is frequently grouped into gain or loss of ion channel function (GOF or LOF, respectively) which is not only corresponding to clinical disease manifestations, but also to differences in drug response. Experimental studies of channel function are therefore important, but laborious and usually focus only on a few variants at a time. Based on known gene-disease-mechanisms, we here infer LOF (518 variants) and GOF (309 variants) of likely pathogenic variants from disease phenotypes of variant carriers. We show regional clustering of inferred GOF and LOF variants, respectively, across the alignment of the entire gene family, suggesting shared pathomechanisms in the SCN/CACNA1 genes. By training a machine learning model on sequence- and structure-based features we predict LOF- or GOF- associated disease phenotypes (ROC = 0.85) of likely pathogenic missense variants. We then successfully validate the GOF versus LOF prediction on 87 functionally tested variants in SCN1/2/8A and CACNA1I (ROC = 0.73) and in exome-wide data from > 100.000 cases and controls. Ultimately, functional prediction of missense variants in clinically relevant genes will facilitate precision medicine in clinical practice.

[more ▼] A set S⊆Fn2 is called degree-d zero-sum if the sum ∑s∈Sf(s) vanishes for all n-bit Boolean functions of algebraic degree at most d. Those sets correspond to the supports of the n-bit Boolean functions of degree at most n−d−1. We prove some results on the existence of degree-d zero-sum sets of full rank, i.e., those that contain n linearly independent elements, and show relations to degree-1 annihilator spaces of Boolean functions and semi-orthogonal matrices. We are particularly interested in the smallest of such sets and prove bounds on the minimum number of elements in a degree-d zero-sum set of rank n. The motivation for studying those objects comes from the fact that degree-d zero-sum sets of full rank can be used to build linear mappings that preserve special kinds of nonlinear invariants, similar to those obtained from orthogonal matrices and exploited by Todo, Leander and Sasaki for breaking the block ciphers Midori, Scream and iScream.

Here we study the analogous problem for the dual volume, a notion that arises from the polarity relation between the hyperbolic space H^3 and the de Sitter space dS^3. The corresponding dual Bonahon-Schläfli formula has been originally deduced from Bonahon's work by Krasnov and Schlenker. Here, making use of the differential Schläfli formula and the properties of the dual volume, we give a (almost) self-contained proof of the dual Bonahon-Schläfli formula, without making use of Bonahon's original result.
