This paper presents a localization system for Unmanned Aerial Vehicles (UAVs) especially designed to be used in infrastructure inspection, where the UAVs have to fly in challenging conditions, such as relatively high altitude (e.g., 15 m), eventually with poor or absent GNSS (Global Navigation Satellite System) signal reception, or the need for a BVLOS (Beyond Visual Line of Sight) operation in some periods. In addition, these infrastructure inspection applications impose the following requirements for the localization system: defect traceability, accuracy, reliability, and fault tolerance. Our system proposes a lightweight solution combining multiple stereo cameras with a robotic total station to comply with these requirements, providing full-state estimation (i.e., position, orientation, and linear and angular velocities) in a fixed and time-persistent reference frame. Moreover, the system can align and fuse all sensor measurements in real-time at high frequency. We have integrated this localization system in our aerial platform, and we have tested its performance for inspection in a real-world viaduct scenario, where the UAV has to operate with poor or absent GNSS signal at high altitude.

Red blood cells in sickle cell anemia (sRBC) are more heterogeneous in their physical properties than healthy red blood cells, spanning adhesiveness, rigidity, density, size, and shape. sRBC with increased adhesiveness to the vascular wall would trigger vaso-occlusive like complications, a hallmark of sickle cell anemia. We investigated whether segregation occurs among sRBC flowing in micron-sized channels and tested the impact of aggregation on segregation. Two populations of sRBC of different densities were separated, labeled, and mixed again. The mixed suspension was flowed within glass capillary tubes at different pressure-drops, hematocrit, and suspending media that promoted or not cell aggregation. Observations were made at a fixed channel position. The mean flow velocity was obtained by using the cells as tracking particles, and the cell depleted layer (CDL) by measuring the distance from the cell core border to the channel wall. The labeled sRBC were identified by stopping the flow and scanning the cells within the channel section. The tube hematocrit was estimated from the number of fluorescence cells identified in the field of view. In non-aggregating media, our results showed a heterogeneous distribution of sRBC according to their density: low-density sRBC population remained closer to the center of the channel, while the densest cells segregated towards the walls. There was no impact of the mean flow velocity and little impact of hematocrit. This segregation heterogeneity could influence the ability of sRBC to adhere to the vascular wall and slow down blood flow. However, promoting aggregation inhibited segregation while CDL thickness was enhanced by aggregation, highlighting a potential protective role against vaso-occlusion in patients with sickle cell anemia.

A large number of studies have detected that within the EU multilevel governance there is a transformation toward a hybrid knowledge co-production that overcomes traditional categories such as locality or embeddedness. There, a sort of sustainable decision-making knowledge is co-developed and theoretically supposed to be applied top-down on the national level of EU member states. However, in practice such processes of unification are always associated with a risk of limited compliance with specific national situations and with a specific national “world of relevancies”. Despite the rise in popularity of these top-down initiatives within international policy levels, there is a lack of studies that empirically analyze how national policy systems respond to these global standardization approaches. Therefore, the central aim of this study is twofold: Based on an exemplary case of an international information system co-produced by an expert group of the European Commission, it first reconstructs whether and how transnational information is integrated on the national policy level. Second, it elucidates factors limiting an application. The results show that this international knowledge system was used for basal purposes and was mainly challenged by non-compliance with national specificities and the existence of alternative knowledge sources.

The FASKU is an economical instrument for recording individual competence expectations of dealing with difficulties and obstacles in daily life. It was originally developed and validated in German by Beierlein, Kemper, Kovaleva, and Rammstedt (2013). In 2019, the authors developed and tested a French version of this scale (FASKU) and tested it for reliability (internal consistency), validity, and measurement equivalence towards the original German Version (see Décieux et al., 2020a). The provided evidence on the quality of the German and the French Version of ASKU (FASKU) indicates that the scales allow a reliable, valid, and economical assessment of subjective competence expectations and that the two language versions can be used to assess and compare self-efficacy in German- and French-speaking populations.

International migration originating from highly developed countries is a crucial component of global migration flows. There are, however, surprisingly little data about the international mobility of the populations of affluent countries. The German Emigration and Remigration Panel Study (GERPS) aims to provide a resource that enables the analysis of individual consequences of international migration as well as the socio-structural consequences for the country of origin. GERPS is based on an origin-based multistage probability sample using the German population registers as a sampling frame. The second wave yields a net sample of roughly 7,000 persons who recently moved abroad from Germany and persons who returned from Germany after having lived abroad. The study follows a multidestination- country-design and enables the comparative analysis of migrants and nonmigrants, who stayed in the country of origin. GERPS is a panel study with at least four waves during a period of at least 24 months. This documentation presents the methods and data of the second wave. It provides information for researchers and invites them to use the new data infrastructure for their own research. [less ▲]

Friendships can be interpreted as voluntary relationships between individuals and characterised as relatively amorphous bond. Since migration usually diversifies people’s social bonds, it can be suggested that in this context friendships have to be reconfigured. Even though friendships are important for societal integration and related to individual well-being, migration research has treated friendships as a side issue. This chapter aims to narrow this gap by answering three questions: Are there significant differences between emigrants and non-mobiles in their number of close friends? What are important factors influencing emigrants’ number of close friends abroad? How does this number develop during the first years after emigration? Based on data from the German Emigration and Remigration Panel Study and the German Socio-Economic Panel, the results show that emigrants have more friends than non-mobiles. Additionally, we find that individual characteristics and cultural distance between emigrant and host society or the intension to stay in the emigration country are significantly related to emigrants’ friendship network size. Furthermore, we find that identification with the emigration country is the most influential factor on the size of the friendship networks during the first 2 years after arrival. Our results also provide some evidence that there is an optimal size of the close-friendship-network. [less ▲]

We address two major challenges in setting up probability-based online panels of migrants, using the German Emigration and Remigration Panel Study (GERPS) as an example. The first challenge is potential spatial and social selectivity in unit response when using push-to-web recruitment. To address the first challenge, we draw on a split ballot experiment with return migrants in wave 1 of GERPS. The related analysis uses population register data and geo data. We use logistic regressions to compare unit nonresponse between a push-to-web-only control group ( n = 5999) and two sub-samples (each n = 1000) with optional paper and pencil interviews (PAPI). The second challenge is panel attrition. To address the second challenge, we investigate the role of individual-level and survey-related factors for panel consent. The regression analysis uses GERPS data of first-wave respondents, estimating panel consent rates for responding remigrants in general ( n = 6395) and in the experiment sample ( n = 2130). We find that the provision of an optional paper questionnaire marginally increases the likelihood of response. The positive correlation of PAPI and response rate, however, is counterbalanced by a negative correlation with the likelihood of panel consent. This suggests a trade-off scenario to the detriment of either response rates or panel participation rates. [less ▲]

Despite a promising start in the Universal Declaration of Human Rights, economic and social rights still retain a second-class status in most national jurisdictions. What explains this reticence with which economic and social rights are (still) regarded? This chapter analyses how the sceptical gaze through which states view economic and social rights legitimises (or attempts to legitimise) government failures to provide for those members of their populace who are in most desperate need, and (unsuccessfully) masks the self-interest that pervades most of international law. The chapter commences with a brief introduction and subsequently proceeds in three subsequent parts. Section 2 demonstrates that cynicism was used as a sword to pierce the normative foundations of economic and social rights generally, and the International Covenant on Economic, Social and Cultural Rights particularly in the early days both before and after its adoption leading to economic and social rights’ lower status in the human rights family; Section 3 posits that cynicism has been relied upon as a shield to offer errant states a defence for not meeting their obligations under both international and national (constitutional) economic and social rights norms; and finally Section 4 argues that a certain amount of cynicism is inherent in the history of economic and social rights and how they advanced through the ages, but more optimistically that a light at the end of the tunnel exists because contemporary developments point to less rather than more cynicism in the area of economic and social rights in today’s world.

6G networks are expected to meet ambitious perfor- mance parameters of coverage, data rates, latency, etc. To fulfill these objectives, the implementation of non-GEO satellite con- stellations is expected to improve coverage, capacity, resilience, etc. as well as the implementation of new advanced network virtualization algorithms in order to optimize network resources. However, the integration of these technologies represents new challenges, such as the execution of network slicing schemes in highly dynamic environments and network awareness require- ments. In this regard, Software Defined Networking (SDN) is seen as a required 6G technology enabler in order to provide better satellite-terrestrial integration approaches and Virtual Network (VN) implementation solutions. In this paper, we present an experimental testbed for non-GEO satellite constellations integration solution and VNE algorithms implementation adapted to highly variable network conditions that builds upon SDN. A laboratory testbed has been developed and validated, consisting in SDN-based satellite-terrestrial dynamic substrate network emulated in Mininet, a Ryu SDN controller with an End-to-End (E2E) Traffic Engineering (TE) application for the VNs estab- lishment and a Virtual Network Embedding (VNE) algorithm implemented in Matlab.

International migration is often characterised as a process of immigration from economically less developed to highly developed countries. Whereas the factors driving those flows and the integration of the respective ethnic groups are widely analysed, the international mobility of the populations of precisely those affluent societies is regularly missed and less-frequently studied. The chapter describes the research design of the German Emigration and Remigration Panel Study as one of the first endeavours to study the internationally mobile populations from prosperous welfare states. Following an origin-based probability sampling of internationally migrating German citizens, it offers survey data to study the consequences of emigration and remigration along the life course. The chapter discusses the quality of this new data infrastructure along the survey lifecycle and compares the distribution of central demographic characteristics in the survey with official reference statistics. The aim is to establish this approach as a new avenue for studying the global lives of internationally mobile populations. [less ▲]

This chapter provides new evidence about the relative differences in the incomes and living conditions of native- and foreign-born households exploiting EU-SILC data for 2007 and 2018. For the 28 countries with a satisfying coverage of immigrant populations, we document where the foreign-born stand along the distribution of incomes and living conditions and then derive their contribution to seven social indicators. We find that individuals living in foreign-born households have lower incomes and higher levels of poverty and deprivation in all countries examined. No clear improvement in the relative position of foreign-born households is observed between 2007 and 2018. Although there is much heterogeneity in the incomes of foreign-born households, their generally disadvantaged situation implies that, on the whole, they tend to push inequality, poverty and deprivation indicators upwards. This effect persists in many countries, albeit mitigated in magnitude, when we account for the different characteristics of foreign-born compared to natives. [less ▲]

Abstract The exposome, the totality of lifetime exposures, is a new and highly complex paradigm for health and disease. Tackling this challenge requires an effort well beyond single individuals or laboratories, where every piece of the puzzle will be vital. The launch of this new Exposome journal coincides with the evolution of the exposome through its teenage years and into a growing maturity in an increasingly open and FAIR (findable, accessible, interoperable, reusable) world. This letter discusses how both authors and the Exposome journal alike can help increase the FAIRness of the chemical structural information and the associated metadata in the journal, aiming to capture more details about the chemistry of exposomics. The proposed chemical structure template can serve as an interoperable supplementary format that is made accessible through the website and more findable by linking the DOI of this data file to the article DOI metadata, supporting further reuse. An additional Transformations template provides authors with a means to connect predecessor (parent, substrate) molecules to successor (transformation product, metabolite) molecules and thus provide FAIR connections between observed (i.e., experimental) chemical exposures and biological responses, to help improve the public knowledgebase on exposome-related transformations. These connections are vital to extend current biochemical knowledge and to fulfil the current Exposome definition of “the cumulative measure of environmental influences and associated biological responses throughout the lifespan including exposures from the environment, diet, behaviour, and endogenous processes”.

Toxicology has been an active research field for many decades, with academic, industrial and government involvement. Modern omics and computational approaches are changing the field, from merely disease-specific observational models into target-specific predictive models. Traditionally, toxicology has strong links with other fields such as biology, chemistry, pharmacology and medicine. With the rise of synthetic and new engineered materials, alongside ongoing prioritisation needs in chemical risk assessment for existing chemicals, early predictive evaluations are becoming of utmost importance to both scientific and regulatory purposes. ELIXIR is an intergovernmental organisation that brings together life science resources from across Europe. To coordinate the linkage of various life science efforts around modern predictive toxicology, the establishment of a new ELIXIR Community is seen as instrumental. In the past few years, joint efforts, building on incidental overlap, have been piloted in the context of ELIXIR. For example, the EU-ToxRisk, diXa, HeCaToS, transQST, and the nanotoxicology community have worked with the ELIXIR TeSS, Bioschemas, and Compute Platforms and activities. In 2018, a core group of interested parties wrote a proposal, outlining a sketch of what this new ELIXIR Toxicology Community would look like. A recent workshop (held September 30th to October 1st, 2020) extended this into an ELIXIR Toxicology roadmap and a shortlist of limited investment-high gain collaborations to give body to this new community. This Whitepaper outlines the results of these efforts and defines our vision of the ELIXIR Toxicology Community and how it complements other ELIXIR activities. [less ▲]

Moving–particularly to a new country–is fraught with risks as migrants leave familiar legal frameworks and cultural institutions behind them. To date, little is known about the psychological determinants of international migration. This chapter helps to fill this gap by analysing data from the first wave of the German Emigration and Remigration Panel Study (GERPS) in combination with data on non-mobile individuals from the German Socio-Economic Panel Study (SOEP). The analyses presented examine whether the risk attitudes of internationally mobile Germans (‘movers’) differ from those of their non-mobile counterparts (‘stayers’). The results show that–with control for key socio-demographic and socio-economic determinants of risk affinity–both emigrants and remigrants report a significantly higher willingness to take risks than stayers. Risk affinity differs within the group of internationally mobile individuals: Emigrants moving to geographically and culturally distant non-European countries report higher risk affinity than those moving to Germany’s neighbouring countries. Emigrants with multiple previous emigration periods are also more willing to take risks. These findings suggest that voluntary emigration from wealthy countries like Germany is only partly a matter of living conditions. Rather, (repeated) emigration seems to be a matter of personality and an expression of a more adventurous lifestyle. [less ▲]

This article investigates how mail based online panel recruitment can be facilitated through incentives. The analysis relies on two incentive experiments and their effects on panel recruitment and the intermediate participation in the recruitment survey. The experiments were implemented in the context of the German Emigration and Remigration Panel Study and encompass two samples of randomly sampled persons. Tested incentives include a conditional lottery, conditional monetary incentives, and the combination of unconditional money-in-hand with conditional monetary incentives. For an encompassing evaluation of the link between incentives and panel recruitment, the article further assesses the incentives’ implications for demographic composition and panel recruitment unit costs. Multivariate analysis indicates that low combined incentives (€5/€5) or, where unconditional disbursement is unfeasible, high conditional incentives (€20) are most effective in enhancing panel participation. In terms of demographic bias, low combined incentives (€5/€5) and €10 conditional incentives are the favored options. The budget options from the perspective of panel recruitment include the lottery and the €10 conditional incentive which break even at net sample sizes of 1,000. [less ▲]
