[more ▼]A novel 2-bit adaptive delta modulation (ADM) algorithm is presented based on uniform scalar quantization and fractional linear prediction (FLP) for encoding the signals modelled by a Gaussian probability density function. The study focusses on two major areas: realization of a 2-bit adaptive quantizer based on Q-function approximation that significantly facilitates quantizer design; and implementation of a recently introduced FLP approach with the memory of two samples, which replaces the first-order linear prediction used in standard ADM algorithms and enables improved performance without increasing transmission costs. It furthermore represents the first implementation of FLP in signal encoding, therefore confirming its applicability in a real signal-processing scenario. Based on the performance analysis conducted on a real speech signal, the proposed ADM algorithm with FLP is demonstrated to outperform other 2-bit ADM baselines by a large margin for the gain in signal-to-noise ratio achieved over a wide dynamic range of input signals. The results of this research indicate that ADM with adaptive quantization based on Q-function approximation and adaptive FLP represents a promising solution for encoding/compression of correlated time-varying signals following the Gaussian distribution.

[more ▼]Recent successes in training word embeddings for NLP tasks have encouraged a wave of research on representation learning for sourcecode, which builds on similar NLP methods. The overall objective is then to produce code embeddings that capture the maximumof program semantics. State-of-the-art approaches invariably rely on a syntactic representation (i.e., raw lexical tokens, abstractsyntax trees, or intermediate representation tokens) to generate embeddings, which are criticized in the literature as non-robustor non-generalizable. In this work, we investigate a novel embedding approach based on the intuition that source code has visualpatterns of semantics. We further use these patterns to address the outstanding challenge of identifying semantic code clones. Wepropose theWySiWiM(“What You See Is What It Means”) approach where visual representations of source code are fed into powerfulpre-trained image classification neural networks from the field of computer vision to benefit from the practical advantages of transferlearning. We evaluate the proposed embedding approach on the task of vulnerable code prediction in source code and on two variationsof the task of semantic code clone identification: code clone detection (a binary classification problem), and code classification (amulti-classification problem). We show with experiments on the BigCloneBench (Java), Open Judge (C) that although simple, ourWySiWiMapproach performs as effectively as state of the art approaches such as ASTNN or TBCNN. We also showed with datafrom NVD and SARD thatWySiWiMrepresentation can be used to learn a vulnerable code detector with reasonable performance(accuracy∼90%). We further explore the influence of different steps in our approach, such as the choice of visual representations or theclassification algorithm, to eventually discuss the promises and limitations of this research direction.

Here, we explore the influence of optical anisotropy on the magneto-optical activity in non-magnetic hyperbolic nanoparticles. We demonstrate that the magneto-optical response is driven by fundamental electric and magnetic dipole modes induced by the hyperbolic dispersion. Magnetic circular dichroism experiments confirm the theoretical predictions and reveal tunable magneto-optical activity across the visible and near infrared spectral range.

[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 outweighs 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 ▼]Introduction: The use of social marketing strategies to induce the promotion of cognitive health has received little attention in research. The objective of this scoping review is twofold: (i) to identify the social marketing strategies that have been used in recent years to initiate and maintain health-promoting behaviour; (ii) to advance research in this area to inform policy and practice on how to best make use of these strategies to promote cognitive health. Methods and analysis: We will use the five-stage methodological framework of Arksey and O’Malley. Articles in English published since 2010 will be searched in electronic databases (the Cochrane Library, DoPHER, the International Bibliography of the Social Sciences, PsycInfo, PubMed, ScienceDirect, Scopus). Quantitative and qualitative study designs as well as reviews will be considered. We will include those articles that report the design, implementation, outcomes and evaluation of programmes and interventions concerning social marketing and/or health promotion and/or promotion of cognitive health. Grey literature will not be searched. Two independent reviewers will assess in detail the abstracts and full text of selected citations against the inclusion criteria. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart for Scoping Reviews will be used to illustrate the process of article selection. We will use a data extraction form, present the results through narrative synthesis and discuss them in relation to the scoping review research questions. Ethics and dissemination: Ethics approval is not required for conducting this scoping review. The results of the review will be the first step to advance a conceptual framework, which contributes to the development of interventions targeting the promotion of cognitive health. The results will be published in a peer-reviewed scientific journal. They will also be disseminated to key stakeholders in the field of the promotion of cognitive health.

[more ▼]We study the problem of symbol detection in downlink coded multiple-input multiple-output (MIMO) systems with precoding and without the explicit knowledge of the channel-state information (CSI) at the receiver. In this context, we investigate the impact of imperfect CSI at the transmitter (CSIT) on the detection performance. We first model the CSIT degradation based on channel estimation errors to investigate its impact on the detection performance at the receiver. To mitigate the effect of CSIT deterioration at the latter, we propose learning based techniques for hard and soft detection that use downlink precoded pilot symbols as training data. We note that these pilots are originally intended for signal-to-interference-plus-noise ratio (SINR) estimation. We validate the approach by proposing a lightweight implementation that is suitable for online training using several state-of-the-art classifiers. We compare the bit error rate (BER) and the runtime complexity of the proposed approaches where we achieve superior detection performance in harsh channel conditions while maintaining low computational requirements. Specifically, numerical results show that severe CSIT degradation impedes the correct detection when a conventional detector is used. However, the proposed learning-based detectors can achieve good detection performance even under severe CSIT deterioration, and can yield 4-8 dB power gain for BER values lower than 10-4 when compared to the classic linear minimum mean square error (MMSE) detector.

[more ▼]Objective Cognitive-driven activity of daily living (ADL) impairment in Parkinson’s disease (PD) is increasingly discussed as prodromal marker for dementia. Diagnostic properties of assessments for this specifc ADL impairment are sparsely investigated in PD. The ability of the Functional Activities Questionnaire (FAQ) for diferentiating between PD patients with normal cognition and with mild cognitive impairment (PD-MCI), according to informant and self-reports, was examined. Global cognitive function in groups with and without mild ADL impairment was compared according to diferent cut-ofs. Methods Multicenter data of 589 patients of an international cohort (CENTRE-PD) were analyzed. Analyses were run separately for informant-rated and self-rated FAQ. Receiver operating characteristic (ROC) analysis was conducted to defne the optimal FAQ cut-of for PD-MCI (≥1), and groups were additionally split according to reported FAQ cut-ofs for PD-MCI in the literature (≥3,≥5). Binary logistic regressions examined the efect of the Montreal Cognitive Assessment (MoCA) score in PD patients with and without mild ADL impairment. Results Two hundred and twenty-fve (38.2%) patients were classifed as PD-MCI. For all three cut-of values, sensitivity was moderate to low (<0.55), but specifcity was moderately high (>0.54) with a tendency of higher values for self-reported defcits. For the self-report, the cut-of≥3 showed a signifcant efect of the MoCA (B= −0.31, p=0.003), where FAQ≥3 patients had worse cognition. No efect for group diferences based on informant ratings was detected. Conclusion Our data argue that self-reported ADL impairments assessed by the FAQ show a relation to the severity of cognitive impairment in PD.

[more ▼]The evolution of the electrical power sector due to the advances in digitalization, decarbonization and decentralization has led to the increase in challenges within the current distribution network. Therefore, there is an increased need to analyze the impact of the smart grid and its implemented solutions in order to address these challenges at the earliest stage, i.e., during the pilot phase and before large-scale deployment and mass adoption. Therefore, this paper presents the scalability and replicability analysis conducted within the European project InteGrid. Within the project, innovative solutions are proposed and tested in real demonstration sites (Portugal, Slovenia, and Sweden) to enable the DSO as a market facilitator and to assess the impact of the scalability and replicability of these solutions when integrated into the network. The analysis presents a total of three clusters where the impact of several integrated smart tools is analyzed alongside future large scale scenarios. These large scale scenarios envision significant penetration of distributed energy resources, increased network dimensions, large pools of flexibility, and prosumers. The replicability is analyzed through different types of networks, locations (country-wise), or time (daily). In addition, a simple replication path based on a step by step approach is proposed as a guideline to replicate the smart functions associated with each of the clusters.

[more ▼]This paper investigates the impact of local traffic pollution on the formation of residential and business districts. While firms benefit from local production externalities, households commute to their workplaces with private vehicles and exert a local pollution externality on the residents living along the urban transport networks. The spatial location of firms and residents endogenously results from the trade-off between the production and pollution externalities and the commuting costs. The analysis shows that in monocentric cities the benefits associated with a fall in per-vehicle pollution are absorbed by rents paid to absentee landlords. When a city includes business and residential districts as well as a district mixing both agents, a lower per-vehicle pollution enlarges the residential districts and shifts the business districts closer to the geographical center of the city. The paper finally studies the optimal city structure. The first-best policies that fully internalize the externalities still foster business agglomeration.

[more ▼]In this paper we present the competitive optimisation of a swarm of Unmanned Aerial Vehicles (UAV) protecting a restricted area from a number of intruders following a Predator–Prey approach. We propose a Competitive Coevolutionary Genetic Algorithm (CompCGA) which optimises the parameters of the UAVs (i.e. predators) to maximise the detection of intruders, while the parameters of the intruders (i.e. preys) are optimised to maximise their intrusion success rate. Having chosen the CACOC (Chaotic Ant Colony Optimisation for Coverage) as the base mobility model for the UAVs, we propose an improved new version, where its behaviour is modified by identifying and optimising new parameters to improve the overall success rate when detecting intruders. Six case studies have been optimised using simulations by performing 30 independent runs (180 in total) of our CompCGA. Finally, we conducted a series of master tournaments (1,800,000 evaluations) using the best specimens obtained from each run and case study to test the robustness of our proposed approach against unexpected intruders. Our surveillance system improved the average percentage of intruders detected with respect to CACOC by a maximum of 126%. More than 90% of intruders were detected on average when using a swarm of 16 UAVs while CACOC’s detection rates are always under 80% in all cases.

[more ▼]The use of a large-scale antenna array (LSAA) has become an important characteristic of multi-antenna communication systems to achieve beamforming gains. For example, in millimeter wave (mmWave) systems, an LSAA is employed at the transmitter/receiver end to combat severe propagation losses. In such applications, each antenna element has to be driven by a radio frequency (RF) chain for the implementation of fully-digital beamformers. This strict requirement significantly increases the hardware cost, complexity, and power consumption. Therefore, constant-modulus analog beamforming (CMAB) becomes a viable solution. In this paper, we consider the scaled analog beamforming (SAB) or CMAB architecture and design the system parameters by solving the beampattern matching problem. We consider two beampattern matching problems. In the first case, both the magnitude and phase of the beampattern are matched to the given desired beampattern whereas in the second case, only the magnitude of the beampattern is matched. Both the beampattern matching problems are cast as a variant of the constant-modulus least-squares problem. We provide efficient algorithms based on the alternating majorization-minimization (AMM) framework that combines the alternating minimization and the MM frameworks and the conventional-cyclic coordinate descent (C-CCD) framework to solve the problem in each case. We also propose algorithms based on a new modified-CCD (M-CCD) based approach. For all the developed algorithms we prove convergence to a Karush-Kuhn-Tucker (KKT) point (or a stationary point). Numerical results demonstrate that the proposed algorithms converge faster than state-of-the-art solutions. Among all the algorithms, the M-CCD-based algorithms have faster convergence when evaluated in terms of the number of iterations and the AMM-based algorithms offer lower complexity.

Drawing on an original dataset of N = 363 editions from N = 95 explicitly global reports from the period 1947–2019, this study documents the rise of reporting and uses citation and content analyses to examine the changing role of science. Reporting based on scientific research and quantitative indicators increases over time and across all sectors, yet particularly striking since the late 1980s and most in sectors dealing with human development and the environment. Drawing on arguments from world society theory, the sociology of quantification and post-truth approaches, this work argues that while reports provide IOs with new legitimacy in science-based governance, their scientised and quantified nature is likely to make IO activities the target of antiscientific populist rhetoric and critical arguments about a reductionist interpretation of science.

A new Competitive Coevolutionary Genetic Algorithm (CompCGA) is proposed to optimise the vehicles’ parameters and escapers’ evasion ability using a predator-prey approach. Our results show that CROMM-MS is not only viable for surveillance tasks but also that its results are competitive in regard to the state-of-the-art approaches.

[more ▼]Declining hours of work per worker in conjunction with a growing work force may give rise to fluctuations between growth regimes. This is shown in an overlapping generations model with two-period lived individuals endowed with Boppart-Krusell preferences (Boppart and Krusell (2020)). On the supply side, economic growth is due to the expansion of consumption-good varieties through endogenous research. A sufficiently negative equilibrium elasticity of the individual supply of hours worked to an expansion in the set of consumption-good varieties destabilizes the steady state so that equilibrium trajectories may fluctuate between two growth regimes, one with and the other without an active research sector. Fluctuations affect intergenerational welfare, the evolution of GDP, and the functional income distribution. A stabilization policy can shift the economy onto its steady-state path. Fluctuations arise for empirically reasonable parameter constellations. The economics of fluctuations between growth regimes is linked to the intergenerational trade of shares and their pricing in the asset market.

The endogeneity between migration, human capital investment, and self-employment is addressed by exploiting exogenous cohort and regional variation in the decision to migrate in the context of Egypt, and parental labour market information. Return migrants’ higher propensity to be self-employed is shown to proceed from participating in significantly more occupations over their work history than non-migrants. In line with Lazear’s framework, estimates confirm that entrepreneurship can be learnt, and that exposure to multiple occupations matters for entrepreneurship.

[more ▼]Mobility of workers living in one country and working in a different country has increased in the European Union. Exposed to commuting factors, cross-border workers (CBWs) constitute a potential high-risk population. But the relationships between health and commuting abroad are under-documented. Our aims were to: (1) measure the prevalence of the perceived health status and the physical health outcomes (activity limitation, chronic diseases, disability and no leisure activities), (2) analyse their associations with commuting status as well as (3) with income and health index among CBWs. Based on the ‘Enquête Emploi’, the French cross-sectional survey segment of the European Labour Force Survey (EU LFS), the population was composed of 2,546,802 workers. Inclusion criteria for the samples were aged between 20 and 60 years and living in the French cross-border departments of Germany, Belgium, Switzerland and Luxembourg. The Health Index is an additional measure obtained with five health variables. A logistic model was used to estimate the odds ratios of each group of CBWs, taking non-cross border workers (NCBWs) as the reference group, controlling by demographic background and labour status variables. A sample of 22,828 observations (2456 CBWs vs. 20,372 NCBWs) was retained. The CBW status is negatively associated with chronic diseases and disability. A marginal improvement of the health index is correlated with a wage premium for both NCBWs and CBWs. Commuters to Luxembourg have the best health outcomes, whereas commuters to Germany the worst. CBWs are healthier and have more income. Interpretations suggest (1) a healthy cross-border phenomenon steming from a social selection and a positive association between income and the health index is confirmed; (2) the existence of major health disparities among CBWs; and (3) the rejection of the spillover phenomenon assumption for CBWs. The newly founded European Labour Authority (ELA) should take into account health policies as a promising way to support the cross-border mobility within the European Union.

[more ▼]Objective: Whether parental presence during their children's painful medical procedures is advantageous with regard to child's pain-related outcomes is questionable. Research regarding this topic is equivocal and additional questions, such as whether levels of parental involvement may play a role as well, remain to be assessed. The purpose of this systematic review is to summarize and critically appraise the literature regarding the impact of parental presence versus absence during their children's painful medical procedures on the child's pain-related outcomes. Methods: The review protocol was registered on Prospero (ID CRD42018116614). A systematic search in PubMed, Web of Science, and PsycArticles resulted in 22 eligible studies incorporating 2157 participants. Studies were considered eligible if they included children (≤ 18 years old) undergoing a painful medical procedure and compared parental presence and/or involvement with parental absence during the procedure. Results: The children's pain-related outcomes included self-reported pain intensity, self-reported fear, anxiety and distress, observed pain-related behavior, and physiological parameters. Overall, evidence points in the direction of beneficial effects of parental presence versus absence with regard to children's self-reported pain intensity and physiological parameters, whereas mixed findings were recorded for children's self-reported fears, anxiety and distress, and observed pain-related behaviors. Conclusions: : In order to provide clear recommendations on how to involve the parent during the procedure, as well as for which type of children and parents parental presence has the best effects, further research is needed, as indicated in this review.

By exploiting individual firm data collected from financial statements and balance sheets, we highlight the determinants of effective tax rates, such as firms’ size, industry, location, and other corporate attributes. We show that larger firms do benefit from lower effective tax rates, and this result is robust to various proxies of size and is even reinforced for profit-making firms.

[more ▼]Background: Access to and use of digital technology are more common among people of higher socioeconomic status. These differences might be due to lack of interest, not having physical access or having lower intentions to use this technology. By integrating the digital divide approach and the User Acceptance of Information Technology (UTAUT) model, this study aims to further our understanding of socioeconomic factors and the mechanisms linked to different stages in the use of Personal Health Records (PHR): desire, intentions and physical access to PHR. Methods: A cross-sectional online and in-person survey was undertaken in the areas of Lorraine (France), Luxembourg, Rhineland-Palatinate and Saarland (Germany), and Wallonia (Belgium). Exploratory factor analysis was performed to group items derived from the UTAUT model. We applied linear and logistic regressions controlling for country-level heterogeneity, health and demographic factors. Results: A total of 829 individuals aged over 18 completed the questionnaire. Socioeconomic inequalities were present in the access to and use of PHR. Education and income played a significant role in individuals' desire to access their PHR. Being older than 65 years, and migrant, were negatively associated with desire to access PHR. An income gradient was found in having a physical access to PHR, while for the subgroup of respondents who expressed desire to have access, higher educational level was positively associated with intentions to regularly use PHR. In fully adjusted model testing the contribution of UTAUT-derived factors, individuals who perceived PHRs to be useful and had the necessary digital skills were more inclined to use their PHR regularly. Social influence, support and lack of anxiety in using technology were strong predictors of regular PHR use. Conclusion: The findings highlight the importance of considering all stages in PHR use: desire to access, physical access and intention to regularly use PHRs, while paying special attention to migrants and people with lower socioeconomic backgrounds who may feel financial constraints and are not able to exploit the potential of PHRs. As PHR use is expected to come with health benefits, facilitating access and regular use for those less inclined could reduce health inequalities and advance health equity.

[more ▼]To expand intermittent renewable electricity sources (RESs), worldwide energy policy makers have introduced fixed feed-in tariffs (FITs). However, FITs typically expire after a limited time period. Due to the intermittent electricity supply of RES, market distortions, and insufficient flexibility options, exclusive participation in wholesale electricity markets might not be a viable business model for RES that no longer receive a FIT. Thus, it remains unclear which RES business models (RBMs) ensure a viable operation of RES in the post FIT era. To close this research gap, we present a typology encompassing five RBM archetypes: wholesale electricity market (1), physical power purchase agreements (2), nonphysical power purchase agreements (3), self-consumption (4), and on-site power-2-X (5). The typology includes three additional service layers, which may enhance the profitability of RBM archetypes by opening up additional revenue streams: infrastructure services (1), electricity storage services (2), and ancillary services (3). We highlight the need for new approaches to quantify the viability of RBM archetypes and services layers under different regulatory, technological, and market conditions. To prevent the imminent decommissioning of existing RESs, policy makers must shape the next era of the energy transition, weighting the implications of market-based and intervention-based energy policy approaches.

[more ▼]A well-known curse of computer security research is that it often produces systems that, while technically sound, fail operationally. To overcome this curse, the community generally seeks to assess proposed systems under a variety of settings in order to make explicit every potential bias. In this respect, recently, research achievements on machine learning based malware detection are being considered for thorough evaluation by the community. Such an effort of comprehensive evaluation supposes first and foremost the possibility to perform an independent reproduction study in order to sharpen evaluations presented by approaches’ authors. The question Can published approaches actually be reproduced? thus becomes paramount despite the little interest such mundane and practical aspects seem to attract in the malware detection field. In this paper, we attempt a complete reproduction of five Android Malware Detectors from the literature and discuss to what extent they are “reproducible”. Notably, we provide insights on the implications around the guesswork that may be required to finalise a working implementation. Finally, we discuss how barriers to reproduction could be lifted, and how the malware detection field would benefit from stronger reproducibility standards—like many various fields already have.

[more ▼]In the financial services industry, many people assume blockchain to have significant impacts. From research and practice, we observe two main paradigms of how organizations interact with blockchain. First, organizations use blockchain to optimize existing processes (blockchain-based business process optimization (BPO)). Second, organizations use blockchain to disrupt existing processes, foster disintermediation, and enable disruptive business models (blockchain-based business process disruption (BPD)). However, we lack scientific research that evaluates its de facto potential. We bridge this gap by following a design science research approach to design blockchain-based business process re-engineering (BPRE) for a letter of credit that combines the advantages of BPO and BPD. We conduct three design cycles and develop three artefacts: a BPO, a BPD, and a BPRE approach. Our BPRE approach combines the advantages of partial disintermediation (i.e., increased efficiency and transparency) with the advantages of intermediaries (i.e., process flexibility, liquidity provision, and dispute mediation).

In the present study, induced pluripotent stem cell colonies (33Qn1 line) were differentiated and collected at four time-points, with DNA methylation assessed using the Illumina Infinium Human Methylation EPIC BeadChip array. Dynamic changes in DNA methylation occurring during differentiation were investigated using a data-driven trajectory inference method. We identified a large number of Bonferroni-significant loci that showed progressive alterations in DNA methylation during neuronal differentiation. A gene-gene interaction network analysis identified 60 densely connected genes that were influential in the differentiation of neurons, with STAT3 being the gene with the highest connectivity.

[more ▼]Climate change is with us. As professionals who place value on evidence-based practice, climate change is something we cannot ignore. The current pandemic of the novel coronavirus, SARS-CoV-2, has demonstrated how global crises can arise suddenly and have a significant impact on public health. Global warming, a chronic process punctuated by acute episodes of extreme weather events, is an insidious global health crisis needing at least as much attention. Many neurological diseases are complex chronic conditions influenced at many levels by changes in the environment. This review aimed to collate and evaluate reports from clinical and basic science about the relationship between climate change and epilepsy. The keywords climate change, seasonal variation, temperature, humidity, thermoregulation, biorhythm, gene, circadian rhythm, heat, and weather were used to search the published evidence. A number of climatic variables are associated with increased seizure frequency in people with epilepsy. Climate change-induced increase in seizure precipitants such as fevers, stress, and sleep deprivation (e.g. as a result of more frequent extreme weather events) or vector-borne infections may trigger or exacerbate seizures, lead to deterioration of seizure control, and affect neurological, cerebrovascular, or cardiovascular comorbidities and risk of sudden unexpected death in epilepsy. Risks are likely to be modified by many factors, ranging from individual genetic variation and temperature-dependent channel function, to housing quality and global supply chains. According to the results of the limited number of experimental studies with animal models of seizures or epilepsy, different seizure types appear to have distinct susceptibility to seasonal influences. Increased body temperature, whether in the context of fever or not, has a critical role in seizure threshold and seizure-related brain damage. Links between climate change and epilepsy are likely to be multifactorial, complex, and often indirect, which makes predictions difficult. We need more data on possible climate-driven altered risks for seizures, epilepsy, and epileptogenesis, to identify underlying mechanisms at systems, cellular, and molecular levels for better understanding of the impact of climate change on epilepsy. Further focussed data would help us to develop evidence for mitigation methods to do more to protect people with epilepsy from the effects of climate change.

[more ▼]Higher education (HE) scholarship often focuses on the so-called ‘entrepreneurial’ university as a consequence of new public management reforms. Simultaneously the remarkable expansion of private HE is said to fragment specialize and diversify HE systems. Such diagnoses are misleading as they ignore wider environmental pressures and simultaneous changes in both public non-profit and for-profit HE. We argue that putative diversity in HE operates as a ceremonial façade behind which large-scale isomorphic change across national HE systems sectors and organizational forms occurs. Multiple causes trigger such change originating in the increasingly global HE environment including a burgeoning international HE regime accounting and accountability practices increased permeability of HE systems facilitated by open borders education markets and global science as well as (neo)liberal ideologies stressing human capital and human rights. As other organizations those in HE become subject to these pressures turning universities into more rationalized standardized and strategic actors.

[more ▼]RATIONALE: Severe alcohol use disorder (SAUD) is a psychiatric condition linked to cerebral and cognitive consequences. SAUD is notably characterized by an overactivation of the reflexive/reward system when confronted with alcohol-related cues. Such overreactivity generates a preferential allocation of attentional resources toward these cues, labeled as attentional biases (AB). Theoretical assumptions have been made regarding the characteristics of AB and their underlying processes. While often considered as granted, these assumptions remain to be experimentally validated. AIMS: We first identify the theoretical assumptions made by previous studies exploring the nature and role of AB. We then discuss the current evidence available to establish their validity. We finally propose research avenues to experimentally test them. METHODS: Capitalizing on a narrative review of studies exploring AB in SAUD, the current limits of the behavioral measures used for their evaluation are highlighted as well as the benefits derived from the use of eye-tracking measures to obtain a deeper understanding of their underlying processes. We describe the issues related to the theoretical proposals on AB and propose research avenues to test them. Four experimental axes are proposed, respectively, related to the determination of (a) the genuine nature of the mechanisms underlying AB; (b) their stability over the disease course; (c) their specificity to alcohol-related stimuli and (d) their reflexive or controlled nature. CONCLUSIONS: This in-depth exploration of the available knowledge related to AB in SAUD, and of its key limitations, highlights the theoretical and clinical interest of our innovative experimental perspectives capitalizing on eye-tracking measures.

[more ▼]How has housing wealth inequality changed for young-adult households in the post-financial crisis period, and what is driving such change? We chart a path for subsequent studies by analysing the previously unexamined post-crisis housing wealth profile of young adults via different angles and using multiple inequality measures. Using household micro-data for 11 European countries (Household Finance and Consumption Survey, 2010–2017) and the United States (Survey of Consumer Finances, 2010–2016), we find that the accumulation of housing assets for 22–44 year olds is unevenly concentrated among high-income homeowners, over and above what would be expected given the well-known decline in homeownership. We describe and assess several potential drivers for these wealth profile changes, finding that the current explanations offered in the literature do not adequately account for the unequal wealth profile of young people. We conclude that a mix of dynamics, including housing market volatility, housing market configurations leading to uneven capital gains and losses, and the increased social selectivity of homeownership intersect to shape the ways that young adults navigate the housing market in post-crisis times.

[more ▼]Growing electric vehicle (EV) dissemination will increase charging infrastructure installation at home. Similar daily routines are associated with high peak loads due to simultaneous EV charging. However, predominantly residential power transmission is not designed for such high loads, yielding charging bottlenecks and restricting future charging at home. Addressing such bottleneck situations and including the EV driver perspective, we introduce a power allocation mechanism that considers the total travel time of the upcoming trip, consisting of actual driving time and time required for charging externally (including the detour to public charging facilities). Assuming that travel time generally negatively correlates with EV driver utility, our optimization model maximizes the resulting utility of EV drivers. Avoiding unnecessary external charging stops due to an insufficient state of charge at the time of departure, our approach generates travel time savings that increase overall EV driver utility. We illustrate our approach using exemplary cases.

[more ▼]This article examines the influence of patients' families in the Schaerbeek asylum for the insane between 1853 and 1914. Through the examination of the institution's medico-administrative registers during four periods of psychiatric internment (admissions, establishment of diagnoses, social relations of the patients, and discharges), the central role played by the patients' entourage in the asylums is revealed. Between high economic capital and favorable legal provisions, families are indeed able to influence the possibilities and modalities of psychiatric internment. However, families' room for manoeuvre is not unlimited. Entries, diagnoses, social relations of patients and discharges are constantly subject to negotiation between the different holders of the asylums' power. Thus, this contribution highlights the way in which the interests of the patients' families clash with those of the asylum's management, the alienist physicians and the public authorities.

[more ▼]Executive bodies can acquire constitutive powers,even if subject to detailed substantive strictures. Constitutive powers give executive bodies the possibility to transform normative understandings of the meaning of norms and of the goals of public action into legal forms. These bodies thus engage in a jurisgenerative process that enables them to progressively delimit their legal mandates in reaction to socio-economic and political realities. The article illustrates this argument by examining the power of the EU Single Resolution Board (SRB) to determine the resolution of a bank in crisis. It concludes that, in view of constitutive powers, the normative demands that the EU legal system places on executive and administrative bodies must be reconsidered. On that basis and to that effect, mechanisms of accountability should be reconceptualised and reoriented.

[more ▼]Plasmonic nanopores are extensively investigated as single molecules detectors. The main limitations in plasmonic nanopore technology are the too fast translocation velocity of the molecule through the pore and the consequent very short analysis times, as well as the possible instabilities due to local heating. An interesting approach to enable longer acquisition times is represented by the ability to stably trap the nanoparticles used to tag molecules close to the nanopore. Here, we theoretically investigate the performance of a magneto-plasmonic nanopore prepared with a thin layer of cobalt sandwiched between two gold layers. A nanopore is then coupled with a bifunctional (magnetic and plasmonic) core–shell nanoparticle made of magnetite (core) covered with a thin layer of gold (shell). By setting the magnetic configuration of the cobalt layer around the pore by an external magnetic field, it is possible to generate a nanoscale magnetic tweezer to trap the nanoparticle at a specific point. Considering a ∼10 nm diameter magnetite nanoparticle, we calculate a trapping force up to 28 pN, an order of magnitude above the force that can be obtained with standard optical or plasmonic trapping approaches. Moreover, the magnetic force pulls the nanoparticle in close contact with the plasmonic nanopore's wall, thus enabling the formation of a nanocavity enclosing a sub-10 nm3 confined electromagnetic field with an average field intensity enhancement up to 230 at near-infrared wavelengths. The presented hybrid magneto-plasmonic system points toward a strategy to improve nanopore-based biosensors for single-molecule detection and potentially for the analysis of various biomolecules.

[more ▼]A strong coupling of the lattice to functional properties is observed in many transition metal oxide systems, such as the ABO(3) perovskites. In the quest for tailor-made materials, it is essential to be able to control the structural properties of the compound(s) of interest. Here thin film solid solutions that combine NdNiO3 and LaNiO3, two materials with the perovskite structure but distinct space groups, are analyzed. Raman spectroscopy and scanning transmission electron microscopy are combined in a synergistic approach to fully determine the mechanism of the structural crossover with chemical composition. It is found that the symmetry transition is achieved by phase coexistence in a way that depends on the substrate selected. These results carry implications for analog-tuning of physical properties in future functional materials based on these compounds.

The present study aimed at evaluating the psychometric properties and measurement invariance of the revised Perceived Locus of Causality Scale (PLOC-R) in physical education and the Behavioral Regulation in Exercise Questionnaire (BREQ-II) during leisure-time translations from English into German and French among youth. Data obtained from 1808 Luxemburgish students supported the five-factor structure of the translated PLOC-R as well as for the BREQ-II and showed good internal reliability as well as concurrent, discriminant, and nomological validity. Measurement invariance analyses across the two languages revealed configural, metric, and partial scalar invariance for both questionnaires. The findings provide promising evidence for the reliability and validity of the translated PLOC-R and BREQ-II and support their use in cross-cultural and physical activity–related motivational research.

In October 2020, N = 523 participated in a second measurement occasion. Participants reported on perceived ageism during the crisis in different domains, their self-perceptions of aging and subjective age. In latent longitudinal regression models, we predicted views on aging at T2 with perceived ageism at T1, while controlling for baseline views on aging and covariates. Perceived ageism at T1 increased self-perceptions of aging as social loss and yielded a trend for physical decline, while there were no effects on subjective age and self-perceptions of aging as continued growth. Views on aging are powerful predictors of well-being and health outcomes in later life. Our data suggest that being the target of ageism during the crisis negatively affects older adults’ self-perceptions of aging and this impact may be felt beyond the current crisis.

[more ▼]Assigning the variations of internal energy into heat or work contributions is a challenging task due to the fact that these properties are trajectory dependent. A number of proposals have been put forward for open quantum systems following an arbitrary dynamics. We here focus on nonequilibrium thermodynamics of a two-level system and explore in addition to the conventional approach, two definitions motivated by either classical work or heat in which the driving Hamiltonian or the trajectory itself, respectively, are used to set up a reference basis. We first give the thermodynamic properties for an arbitrary dynamics and illustrate the results on the Bloch sphere. Then, we solve the particular example of a periodically driven qubit interacting with a dissipative and decoherence bath. Our results illustrate the trajectory-dependent character of heat and work and how contributions originally assigned to dissipation in the Lindblad equation can become a coherent part assigned to work.

[more ▼]We consider the problem of estimating the joint distribution of n independent random variables. Given a loss function and a family of candidate probabilities, that we shall call a model, we aim at designing an estimator with values in our model that possesses good estimation properties not only when the distribution of the data belongs to the model but also when it lies close enough to it. The losses we have in mind are the total variation, Hellinger, Wasserstein and L_p-distances to name a few. We show that the risk of our estimator can be bounded by the sum of an approximation term that accounts for the loss between the true distribution and the model and a complexity term that corresponds to the bound we would get if this distribution did belong to the model. Our results hold under mild assumptions on the true distribution of the data and are based on exponential deviation inequalities that are non-asymptotic and involve explicit constants. Interestingly, when the model reduces to two distinct probabilities, our procedure results in a robust test whose errors of first and second kinds only depend on the losses between the true distribution and the two tested probabilities.

[more ▼]Concerns about a democratic deficit in the European Union reached new heights in recent years, as the organization has had to address a number of highly politicized challenges. In this context, the question of how much oversight should be exercised by the European Parliament (ep) and national parliaments individually or collectively becomes increasingly salient. Against this background, this article argues that on the issue of Brexit the ep has been quick to carve out a role for itself. However, unlike in previous trade negotiations, national parliaments took a backseat on Brexit despite its potential impact on member states. This is largely due to the similarity of national and party positions on Brexit. In addition, the way the different interparliamentary bodies addressed Brexit reveals the limitations of these bodies in terms of their powers and the depth of their discussions.

[more ▼]We wanted to address two critical limitations of research on mindfulness and motivational conflict, by (a) distinguishing between conflict experiences and conflict reactivity and (b) by applying a typological approach, exploring natural combinations of two core qualities of (state) mindfulness: present moment awareness and a nonjudgmental stance. Using an experience-sampling (ES) design (N = 107 on the personal and 3862 at the observational level) with baseline and posttest measures of general affective wellbeing, we found that between-person differences in everyday conflict reactivity (i.e., perseverative and self-evaluative reactions toward conflict experiences) but not in conflict experiences per se (i.e., feeling that one wants to or should do something else) predicted impaired affective well-being after the ES period. Furthermore, multilevel latent profile analysis showed that momentary conflict reactivity was lowest when participants reported to be both momentarily aware and nonjudgmental, mirroring the comprehensive mindfulness experience. These effects existed while controlling for baseline and accompanying affect as well as for conflict intensity, strengthening the idea that motivational conflict itself is not a critical instance of self-regulation failure and that being mindful may contribute to remain functionally efficient and psychological well-adjusted.

[more ▼]Factorial survey experiments have been widely used to study recruiters’ hiring intentions. Respondents are asked to evaluate hypothetical applicant descriptions, which are experimentally manipulated, for hypothetical job descriptions. However, this methodology has been criticized for putting respondents in hypothetical situations that often only partially correspond to real-life hiring situations. It has been proposed that this criticism can be overcome by sampling real-world vacancies and the recruiters responsible for filling them. In such an approach, only the applicants’ descriptions are hypothetical; respondents are asked about a real hiring problem, which might increase internal and external validity. In this study, we test whether using real vacancies triggers more valid judgments compared to designs based on hypothetical vacancies. The growing number of factorial survey experiments conducted in employer studies makes addressing this question relevant, both for methodological and practical reasons. However, despite the potential implications for the validity of data, it has been neglected so far. We conducted a factorial survey experiment in Luxembourg, in which respondents evaluated hypothetical applicants referring either to a currently vacant position in their company or to a hypothetical job. Overall, we found little evidence for differences in responses by the design of the survey experiment. However, the use of real vacancies might prove beneficial depending on the research interest. We hope that our comparison of designs using real and hypothetical vacancies contributes to the emerging methodological inquiry on the possibilities and limits of using factorial survey experiments in research on hiring.

[more ▼]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.

[more ▼]In this study, we describe the results of a series of co-creation workshops in museums with the goal of designing future digital cultural collections. Ranging from exhibition teasers to comprehensive virtual galleries, digital collections are an increasingly prominent feature of many museum websites but remain a largely unexplored facet of the visitor experience. Building on research in museum experience design, which suggests that involving the public in the development of on-site museum spaces and technologies supports better engagement, we investigated how this translates into digital-only contexts. We invited members of the public (N = 12) to the Luxembourg National Museum of History and Art for a series of design jams to investigate how non-experts envision the future of digital interactivity with museums through a series of ideation and rapid prototyping activities. Our analysis of the workshops and resulting prototypes reveals the design space of digital collections across three continuums of experience: individual/social, creation/consumption, and complementary/standalone. We conclude with design implications, namely how museum professionals can apply these dimensions to the design and implementation of digital collections.

[more ▼]Abstract Metaproteomics has matured into a powerful tool to assess functional interactions in microbial communities. While many metaproteomic workflows are available, the impact of method choice on results remains unclear. Here, we carry out a community-driven, multi-laboratory comparison in metaproteomics: the critical assessment of metaproteome investigation study (CAMPI). Based on well-established workflows, we evaluate the effect of sample preparation, mass spectrometry, and bioinformatic analysis using two samples: a simplified, laboratory-assembled human intestinal model and a human fecal sample. We observe that variability at the peptide level is predominantly due to sample processing workflows, with a smaller contribution of bioinformatic pipelines. These peptide-level differences largely disappear at the protein group level. While differences are observed for predicted community composition, similar functional profiles are obtained across workflows. CAMPI demonstrates the robustness of present-day metaproteomics research, serves as a template for multi-laboratory studies in metaproteomics, and provides publicly available data sets for benchmarking future developments.

[more ▼]Active Labour Market Policies (ALMPs) are the subject of ongoing interest, which has included the framing of ALMPs as the re-commodification of labour. It has also been argued that Sen’s Capability Approach (CA) offers the potential to reconsider ALMPs from a more progressive viewpoint – so, is this the case and to what extent is, or can, the CA be a helpful research and analytical tool with which to study ALMPs? These questions are addressed through a reflexive examination of a study of Danish ALMPs, which utilized the CA and key themes of capabilities promotion, voice and choice. The CA influenced all aspects of the research design, methods and analysis. It is argued that the CA is a helpful methodology in bringing a new perspective to studying ALMPs. Additionally, the study raised concerns about the trajectory of the Danish ALMPs studied and possible alternatives to current approaches.

[more ▼]The European Union’s role in international health issues is of particular importance in the context of the Covid-19 pandemic. The Union aims to strengthen global health policy, in order to build a European Health Union and consolidate its role in the international scene. Article 168 TFEU enables the Union to collaborate with international organisations and partner countries and to participate in the WHO governing bodies despite the absence of full party status. The alignment of internal policies with the objective of protection and improvement of human health gives the Union the implied external competence to participate in international agreements and envisage its active role in the elaboration of an international pandemic treaty. Besides, the Union has recourse to international trade measures in order to preserve the level of human health protection. The global approach of its external action objectives enables the Union to promote human health protection as a value in the conduct of its external policies and to support partner countries in their response to health threats. The Union gradually becomes a unified actor in global health security preparedness and response capacity.

While a Dickman limit was proved in \cite{PW04} in the case of $d=2$, in dimensions three and higher, \cite{BLP06} showed a Gaussian central limit theorem when $\alpha=1$, with a rate of convergence of the order $(\log s)^{-(d-2)/4} (\log \log s)^{(d+1)/2}$. In this paper, we extend these results and prove a central limit theorem in any dimension $d \ge 3$ for any $\alpha>0$. Moreover, making use of recent results in Stein's method for region-stabilizing functionals, we provide presumably optimal non-asymptotic bounds of the order $(\log s)^{-(d-2)/2}$ on the Wasserstein and the Kolmogorov distances between the distribution of the total $\alpha$-powered length of rooted edges, suitably normalized, and that of a standard Gaussian random variable.

[more ▼]The first wave of the COVID-19 pandemic led to decreases in electricity demand and a rising share of Renewable Energy Sources in various countries. In Germany, the average proportion of net electricity generation via Renewable Energy Sources rose above 55% in the first half of 2020, as compared to 47% for the same period in 2019. Given these altered circumstances, in this paper we analyze how the German and other European electricity systems behaved during the COVID-19 pandemic. We use data visualization and descriptive statistics to evaluate common figures for electricity systems and markets, comparing developments during the COVID-19 pandemic with those of previous years. Our evaluation reveals noticeable changes in electricity consumption, generation, prices, and imports/exports. However, concerning grid stability and ancillary services, we do not observe any irregularities. Discussing the role of various flexibility options during the COVID-19 pandemic, a relatively higher grid capacity resulting from a decreased electricity consumption, in particular, may have contributed to grid stability.

[more ▼]Objectives. Our understanding of how societal conditions and educational policies influence cognitive development across the life course is improving. We tested the extent to which inequality of educational opportunity (IEO), the country- and cohort-specific correlation of parents' and their offspring's length of schooling, offers systematically different opportunities to contribute to cognitive development, which in turn influences cognitive abilities up to older ages. Methods. A total of 46,972 individuals of three cohorts born 1940–63 from 16 European countries and Israel provided up to six cognitive assessments and information on covariates in the SHARE survey 2004–2017. Individual-level data were linked to indicators of IEO at time of schooling, and economic, health, and human development, provided by World Bank, WHO, and the UN. Results. In multilevel (mixed-effects) models with random individual and country-cohort effects and adjusted for a large set of confounders, higher IEO was associated with lower levels of cognitive functioning in men and women. Interaction analyses suggested lower cognitive levels particularly of women who were schooled in higher IEO contexts and had lower educational attainment. Associations with rate of change in cognitive functioning were present only in women, however there was little clinically relevant cognitive decline across the window of observation. Result patterns were mostly consistent after including additional contextual indicators, and in a subsample with childhood information. Discussion. Findings suggest that IEO is able to substantially influence cognitive development with long-lasting impacts. Lower-educated women of the cohorts under investigation may have been particularly vulnerable to high-inequality educational contexts.

[more ▼]Melanoma is the deadliest skin cancer. Despite improvements in the understanding of the molecular mechanisms underlying melanoma biology and in defining new curative strategies, the therapeutic needs for this disease have not yet been fulfilled. Herein, we provide evidence that the Activating Molecule in Beclin-1-Regulated Autophagy (Ambra1) contributes to melanoma development. Indeed, we show that Ambra1 deficiency confers accelerated tumor growth and decreased overall survival in Braf/Pten-mutated mouse models of melanoma. Also, we demonstrate that Ambra1 deletion promotes melanoma aggressiveness and metastasis by increasing cell motility/invasion and activating an EMT-like process. Moreover, we show that Ambra1 deficiency in melanoma impacts extracellular matrix remodeling and induces hyperactivation of the focal adhesion kinase 1 (FAK1) signaling, whose inhibition is able to reduce cell invasion and melanoma growth. Overall, our findings identify a function for AMBRA1 as tumor suppressor in melanoma, proposing FAK1 inhibition as a therapeutic strategy for AMBRA1 low-expressing melanoma.

[more ▼]PURPOSE: High level of sedentary behavior (SB) may cause a number of health complaints (nHC) and lead to reduced self-rated health (SRH) in young people. The purpose of this study was to determine the relationship between SB, the magnitude of nHC, SRH, body mass index (BMI), and whether the amount of physical activity (PA) moderates this relationship. METHODS: The data was obtained from Youth Survey Luxembourg 2019 (N = 2802). The population characteristics include sociodemographic data such as age, gender, and socio-economics status (SES) (0 = low to 18 = high). The severity of nHC was the sum score of headaches, stomach aches, back aches, depression, irritableness, nervousness, dizziness, and difficulty falling asleep (0 = low to 32 = high). BMI was calculated by dividing body weight to the square of body height (kg/m2). SRH was measured on a 5-point scale (1 = very good to 5 = very bad). PA and SB were generated from factor analyses of the questionnaire items. SB is separated between leisure and gaming. Multiple regression analysis, adjusted for age, gender, and SES, was used to determine the relationships between SB, nHC, BMI, and SRH, and the moderating effect of PA. RESULTS: Out of the participants, 54% were female and 46% were male with the mean age of 22 ± 4 years (16-29 years). The mean SES was 9.3 ± 2.2 (1-13), BMI was 23 ± 4 kg/m2 (14-47 kg/m2), severity of the nHC was 9 ± 6 (0-32), and SRH was 1.8 ± 0.6 (1-5). The multiple regression analysis shows that high SB through leisure is associated with more severe nHC (unstandardized coefficient b = .49, p < .01). However, PA can decrease nHC (b = .39, p < .01) for participants with high leisure SB. No association has been found between SRH, BMI, and leisure SB. Furthermore, an increase in SB through gaming is associated with higher BMI (b = .35, p < .01) and worse SRH (b = .09, p < .00). A relationship between the severity of nHC and gaming is not found. In all cases, a higher PA shows a significantly better nHC, SRH, and BMI. CONCLUSIONS: The results show that PA has a positive moderating effect of the relationship on leisure SB and nHC in young people in Luxembourg. Increased SB causes higher nHC, worse SRH, and higher BMI and young people who do more PA have lower severity in nHC, and better BMI and SRH. Therefore, it is important for young people to reduce SB and implement a sufficient amount of PA to improve overall health.

[more ▼]We investigate the link between resource revenues volatility and institutions. We build a stochastic differential game with two players (conservatives vs . liberals) lobbying for changing the institutions in their preferred directions. First, uncertainty surrounds the dynamics of institutions and the resource revenues. Second, the lobbying power is asymmetric, the conservatives’ power being increasing with resource revenues. We show the existence of a unique equilibrium in the set of affine strategies. We then examine to which extent uncertainty leads to more liberal institutions in the long run, compared to the deterministic case. We finally explore the institutional impact of volatility using a database covering 91 countries over the period 1973–2005. Focusing on financial liberalization, we find that as oil revenue volatility increases, liberalization goes down. This result is robust to different specifications and sample distinctions.

[more ▼]This paper examines the effect of risk disclosure on firm operational efficiency using a unique database of nonfinancial, and non-utility French firms belonging to the SBF 120 index over the period 2007–2015. In a first step, we use a data envelopment analysis output-oriented variable returns to scale model to determine firm operational efficiency scores based on one output (i.e., sales revenue) and three inputs (i.e., net property, plant, and equipment; cost of goods sold; and selling, general, and administrative costs). These scores are used in a second step to estimate the effect of risk disclosure on operational efficiency after controlling for a set of other factors. The empirical results show a statistically significant positive relation between risk disclosure and operational efficiency, suggesting that firms tend to be relatively more efficient when they disclose more about their risk exposure. Overall, we provide evidence that firms with greater risk disclosure are seen by stakeholders as more credible and trustworthy, leading them to conduct better transactions and, consequently, to improve their operational efficiency. This result is consistent with the notion that stakeholders perceive transparent firms positively, particularly those revealing bad news.
