Genome-wide association studies (GWAS) have identified hundreds of loci associated with Crohns disease (CD), however, as with all complex diseases, deriving pathogenic mechanisms from these non-coding GWAS discoveries has been challenging. To complement GWAS and better define actionable biological targets, we analysed sequenced data from more than 30,000 CD patients and 80,000 population controls. We observe rare coding variants in established CD susceptibility genes as well as ten genes where coding variation directly implicates the gene in disease risk for the first time. [less ▲]

Understanding recovery of consciousness and elucidating its underlying mechanism is believed to be crucial in the field of basic neuroscience and medicine. Ideas such as the global neuronal workspace and the mesocircuit theory hypothesize that failure of recovery in conscious states coincide with loss of connectivity between subcortical and frontoparietal areas, a loss of the repertoire of functional networks states and metastable brain activation. We adopted a time-resolved functional connectivity framework to explore these ideas and assessed the repertoire of functional network states as a potential marker of consciousness and its potential ability to tell apart patients in the unresponsive wakefulness syndrome (UWS) and minimally conscious state (MCS). In addition, prediction of these functional network states by underlying hidden spatial patterns in the anatomical network, i.e. so-called eigenmodes, were supplemented as potential markers. By analysing time-resolved functional connectivity from fMRI data, we demonstrated a reduction of metastability and functional network repertoire in UWS compared to MCS patients. This was expressed in terms of diminished dwell times and loss of nonstationarity in the default mode network and fronto-parietal subcortical network in UWS compared to MCS patients. We further demonstrated that these findings co-occurred with a loss of dynamic interplay between structural eigenmodes and emerging time-resolved functional connectivity in UWS. These results are, amongst others, in support of the global neuronal workspace theory and the mesocircuit hypothesis, underpinning the role of time-resolved thalamo-cortical connections and metastability in the recovery of consciousness.

Protein therapeutics play an important role in controlling the functions and activities of disease-causing proteins in modern medicine. Despite protein therapeutics having several advantages over traditional small-molecule therapeutics, further development has been hindered by drug complexity and delivery issues. However, recent progress in deep learning-based protein structure prediction approaches such as AlphaFold opens new opportunities to exploit the complexity of these macro-biomolecules for highly-specialised design to inhibit, regulate or even manipulate specific disease-causing proteins. Anti-CRISPR proteins are small proteins from bacteriophages that counter-defend against the prokaryotic adaptive immunity of CRISPR-Cas systems. They are unique examples of natural protein therapeutics that have been optimized by the host-parasite evolutionary arms race to inhibit a wide variety of host proteins. Here, we show that these Anti-CRISPR proteins display diverse inhibition mechanisms through accurate structural prediction and functional analysis. We find that these phage-derived proteins are extremely distinct in structure, some of which have no homologues in the current protein structure domain. Furthermore, we find a novel family of Anti-CRISPR proteins which are structurally homologous to the recently-discovered mechanism of manipulating host proteins through enzymatic activity, rather than through direct inference. Using highly accurate structure prediction, we present a wide variety of protein-manipulating strategies of anti-CRISPR proteins for future protein drug design. [less ▲]

The study of the brain’s dynamical activity is opening a valuable source of assistance for the clinical diagnosis of patients with disorders of consciousness (DOC). For example, dysfunctional spread of naturalistic and synthetic stimuli has proven useful to characterize hampered consciousness. However, understanding of the mechanisms behind loss of consciousness following brain injury is still missing. Here, we study the propagation of endogenous and in-silico exogenous perturbations in patients with DOC, based upon directed and causal interactions estimated from resting-state fMRI. We found that patients with DOC suffer decreased capacity for neural propagation and responsiveness to events. Particularly, that loss of consciousness is related to the malfunctioning of two neural circuits: the posterior cortical regions failing to convey information, in conjunction with reduced broadcasting of information from subcortical, temporal, parietal and frontal regions. These results seed light on the mechanisms behind DOC, thus opening new possibilities for clinical applications. [less ▲]

Thanks to the relative ease of finding and characterizing small planets around M dwarf stars, these objects have become cornerstones in the field of exoplanet studies. The current paucity of planets in long-period orbits around M dwarfs make such objects particularly compelling as they provide clues about the formation and evolution of these systems. In this study, we present the discovery of TOI-2257 b (TIC 198485881), a long-period (35 d) sub-Neptune orbiting an M3 star at 57.8pc. Its transit depth is about 0.4%, large enough to be detected with medium-size, ground-based telescopes. The long transit duration suggests the planet is in a highly eccentric orbit ($e \sim 0.5$), which would make it the most eccentric planet that is known to be transiting an M-dwarf star. We combined TESS and ground-based data obtained with the 1.0-m SAINT-EX, 0.60-m TRAPPIST-North and 1.2-m FLWO telescopes to find a planetary size of 2.2 $R_{\oplus}$ and an orbital period of 35.19 days. In addition, we make use of archival data, high-resolution imaging, and vetting packages to support our planetary interpretation. With its long period and high eccentricity, TOI-2257 b falls in a novel slice of parameter space. Despite the planet's low equilibrium temperature ($\sim$ 256 K), its host star's small size ($R_* = 0.311 \pm{0.015}$) and relative infrared brightness (K$_{mag}$ = 10.7) make it a suitable candidate for atmospheric exploration via transmission spectroscopy.

Recently, significant advances have been made by identifying the levels of synchronicity of the underlying dynamics of a given brain state. This research has demonstrated that unconscious dynamics tend to be more synchronous than those found in conscious states, which are more asynchronous. Here we go beyond this dichotomy to demonstrate that the different brain states are always underpinned by spatiotemporal chaos but with dissociable turbulent dynamics. We investigated human neuroimaging data from different brain states (resting state, meditation, deep sleep, and disorders of consciousness after coma) and were able to distinguish between them using complementary model-free and model-based measures of turbulent information transmission. Our model-free approach used recent advances describing a measure of information cascade across spatial scales using tools from turbulence theory. Complementarily, our model-based approach used exhaustive in silico perturbations of whole-brain models fitted to the empirical neuroimaging data, which allowed us to study the information encoding capabilities of the brain states. Overall, the current framework demonstrates that different levels of turbulent dynamics are fundamental for describing and differentiating between brain states. [less ▲]

The Brain Imaging Data Structure (BIDS) established community consensus on the organization of data and metadata for several neuroimaging modalities. Traditionally, BIDS had a strong focus on functional magnetic resonance imaging (MRI) datasets and lacked guidance on how to store multimodal structural MRI datasets. Here, we present and describe the BIDS Extension Proposal 001 (BEP001), which adds a range of quantitative MRI (qMRI) applications to the BIDS. In general, the aim of qMRI is to characterize brain microstructure by quantifying the physical MR parameters of the tissue via computational, biophysical models. By proposing this new standard, we envision standardization of qMRI which makes multicenter dissemination of interoperable data possible. As a result, BIDS can act as a catalyst of convergence between qMRI methods development and application-driven neuroimaging studies that can help develop quantitative biomarkers for neural tissue characterization. Finally, our BIDS extension offers a common ground for developers to exchange novel imaging data and tools, reducing the practical barriers to standardization that is currently lacking in the field of neuroimaging.

We present extensive empirical evidence showing that current Bayesian simulation-based inference algorithms are inadequate for the falsificationist methodology of scientific inquiry. Our results collected through months of experimental computations show that all benchmarked algorithms - (s)npe, (s)nre, snl and variants of abc – may produce overconfident posterior approximations, which makes them demonstrably unreliable and dangerous if one’s scientific goal is to constrain parameters of interest. We believe that failing to address this issue will lead to a well-founded trust crisis in simulation-based inference. For this reason, we argue that research efforts should now consider theoretical and methodological developments of conservative approximate inference algorithms and present research directions towards this objective. In this regard, we show empirical evidence that ensembles are consistently more reliable. [less ▲]

The vast Federmessergruppen site of Lommel-Maatheide, which is located in the Campine region (Northern Belgium), revealed the presence of numerous Final Palaeolithic concentrations situated on a large Late Glacial sand ridge on the northern edge of a contemporary lake. This situation offers a unique possibility for a large-scale functional analysis in order to understand the occupation of such a Late Glacial dune landscape. The variable preservation state of the lithic artefacts permitted to evaluate in detail the impact of post-depositional processes on the potential of functional studies. Also, the impact of excavation protocols on the preservation of wear traces and residues was evaluated, in particular the impact of mechanical sieving. The integrated functional research that included the microscopic examination of wear traces, fractures and residues, next to experimentation, permitted the identification of a range of crafting and hunting activities, thereby demonstrating the potential of such assemblages for obtaining innovative insights into Late Glacial site dynamics in spite of a varying preservation state.

In power systems, large-scale optimisation problems are extensively used to plan for capacity expansion at the supranational level. However, their cost-optimal solutions are often not exploitable by decision-makers who are preferably looking for features of solutions that can accommodate their different requirements. This paper proposes a generic framework for addressing this problem. It is based on the concept of the epsilon-optimal feasible space of a given optimisation problem and the identification of necessary conditions over this space. This framework has been developed in a generic case, and an approach for solving this problem is subsequently described for a specific case where conditions are constrained sums of variables. The approach is tested on a case study about transmission expansion planning of the European electricity network to determine necessary conditions on the minimal investments in transmission, storage and generation capacity.

Walt Whitman was a Long-Island born poet who is most notably known for Leaves of Grass (1855), a work that was inspired by Ralph Waldo Emerson’s call for great poets to render the genuine American experience. In this collection, Whitman takes the voice of a democratic poet on and “prepares us for the perception of a single, universal truth and for our subsequent transformation into the kind of people we need to be” (Brink 2013, xv). Whitman was always close to US pop culture and its (anti)heroes. The nineteenth-century American poet is at the heart of America’s culture, which is shown by, for example, John Keating and his rebellious schoolboys chanting Whitman’s eponymous line of “O Captain! My Captain!” in Peter Weir’s Dead Poets Society (1989) and the many references to Whitman’s work in Breaking Bad (2008-2013) (Bolonik 2013). To the question “Who is the quintessential American?,” Elisabeth Panttaja Brinke, writer, editor and educator who taught literature at Harvard University, Tufts University and Boston College, argues it is “Whitman” (2013, xxii), mainly because of the poet’s representations of both democracy and nature.

What if the Emersonian Sublime was still an invitation? I want to believe that the Emersonian Sublime is more than a plea for self-reliance. It is an uplifting call to reexplore our inner self and to develop a genuine sense of broader responsibility toward nonhumans and humans alike. In the light of the global ecological crisis and pandemic, the Emersonian Sublime urges us not to repeat our “failures and follies” but to deeply reflect upon their severe consequences, to learn from them, and to turn them into “justice” for all. Reconsidering our actions and lifestyle also compels us to redefine our relationship with what we have so far viewed as beautiful or sublime. The “nonconformist” individual is not exactly a social outcast, or one who renounces any interactions with other beings. Emersonian nonconformism highlights the urgency to stop blindly embracing everything that our society has thrown at us and to constantly question the legitimacy and utility of both our and others’ actions. After all, the “transparent eye-ball” metaphor itself might also be an invitation to start unveiling the appearances that were designed to conceal and protect injustices, and to begin to find problems where we had always seen solutions.

Further, we asked what counts as a social chunk in WM: two individuals involved in a meaningful interaction or just spatially close and face-to-face. In three experiments with a delayed change-detection task, participants had to report whether a probe-array was the same of, or different from a sample-array featuring two or three dyads of bodies either face-to-face (facing array) or back-to-back (non-facing array). In Experiment 1, where facing dyads depicted coherent, meaningful interactions, participants were more accurate to detect changes in facing (vs. non-facing) arrays. A similar advantage was found in Experiment 2, even though facing dyads depicted no meaningful interaction. In Experiment 3, we introduced a secondary task (verbal shadowing) to increase WM load. This manipulation abolished the advantage of facing (vs. non-facing) arrays, only when facing dyads depicted no meaningful interactions. These results show that WM uses representation of interaction to chunk crowds in social groups. The mere facingness of bodies is sufficient on its own to evoke representation of interaction, thus defining a social chunk in WM; although the lack of semantic anchor makes chunking fainter and more susceptible to interference of a secondary task [less ▲]

The nth term of an automatic sequence is the output of a deterministic finite automaton fed with the representation of n in a suitable numeration system. In this paper, instead of considering automatic sequences built on a numeration system with a regular numeration language, we consider these built on languages associated with trees having periodic labeled signatures and, in particular, rational base numeration systems. We obtain two main characterizations of these sequences. The first one is concerned with r-block substitutions where r morphisms are applied periodically. In particular, we provide examples of such sequences that are not morphic. The second characterization involves the factors, or subtrees of finite height, of the tree associated with the numeration system and decorated by the terms of the sequence. [less ▲]

We generalize the greedy and lazy β-transformations for a real base β to the setting of alternate bases β = (β0, . . . , βp−1), which were recently introduced by the first and second authors as a particular case of Cantor bases. As in the real base case, these new transformations, denoted Tβ and Lβ respectively, can be iterated in order to generate the digits of the greedy and lazy β-expansions of real numbers. The aim of this paper is to describe the dynamical behaviors of Tβ and Lβ. We first prove the existence of a unique absolutely continuous (with respect to an extended Lebesgue measure, called the p-Lebesgue measure) Tβ-invariant measure. We then show that this unique measure is in fact equivalent to the p-Lebesgue measure and that the corresponding dynamical system is ergodic and has entropy 1/p log(βp−1 · · · β0). We then express the density of this p measure and compute the frequencies of letters in the greedy β-expansions. We obtain the dynamical properties of Lβ by showing that the lazy dynamical system is isomorphic to the greedy one. We also provide an isomorphism with a suitable extension of the β- shift. Finally, we show that the β-expansions can be seen as (βp−1 · · · β0 )-representations over general digit sets and we compare both frameworks. [less ▲]

In the vast collection of documents made available to the public by the Foucault Reading Records project, many of the manuscripts have a very special status, since they are in fact lecture notes taken during the years of study in Paris where Foucault obtained his degrees in philosophy and psychology, at the end of a double course of study carried out between 1946 and 1953, at the ENS and the Sorbonne. Placed side by side, these documents reveal the portrait of a Foucault who, between the ages of twenty and twenty-seven, trained with some of the new masters of the University at the Liberation, took part in the age-old and prestigious game of the Agrégation in philosophy and enrolled among the very first students of the new psychology course at the University of Paris.

This short and prospective article deals with Johannes Hartmann (1568-1631), who is reputed as having been the first professor of chemistry at the University of Marburg. ‘For Hartmann’, Bruce T. Moran has written, ‘the road to the laboratory of chemical medicine in Marburg began in Kassel, at the court of the university’s protector, the Landgrave Moritz of Hesse (1572-1632)’. Having studied at Wittenberg, Hartmann was appointed as a mathematician in Kassel and was chosen to fill the chair of mathematics when the incumbent died. He received a medical degree in 1606 and ‘began a brief correspondence with the French Paracelsian, Joseph Duchesne (Quercetanus) (c. 1544-1609), who had visited Kassel in 1604’. Moritz had become captivated by the study of occult philosophy, especially in relation to alchemy, and was well on his way to amassing an extensive collection of alchemical, Cabbalistic, and Paracelsian manuscripts, and to fashioning a court circle of alchemical and medical adepts. Thus, ‘in 1608, he enthusiastically received a suggestion from Hartmann for founding a collegium chymicum at Marburg’ and he ‘chose to invest Hartmann with a new university role and a new title – Professor publicus chymiatriae’.

Depuis le début des années 2010, une série de nouveaux accords ou de processus de négociations commerciaux entre de grands blocs géographiques ont émergé dans le monde. L’Union Européenne (UE) et les États-Unis ont à ce titre joué un rôle de premier plan dans ces initiatives et dans leurs proliférations. Face à l’impact grandissant de la globalisation sur le quotidien des citoyens, les assemblées législatives tendent à s’impliquer progressivement dans ces processus diplomatiques et à gagner en importance et en visibilité dans leur fonction vis-à-vis de ces accords. Si bien qu’aujourd’hui, toute personne s’intéressant de près ou de loin à l’étude des accords commerciaux ne peut plus ignorer le rôle qu’y jouent les parlements des États impliqués dans ces processus. Les négociations du Partenariat Transatlantique de Commerce et d’Investissement (TTIP), de l’Accord Économique et Commercial Global (CETA) et de l’Accord de Partenariat Transpacifique (TPP) représentent ainsi de bons indicateurs du rôle, des atouts et des limites que les interventions d’un parlement dans un processus de négociation peuvent rencontrer en fonction du contexte politique ou institutionnel et de l’appui de l’opinion publique. Le Parlement européen et le Congrès américain constituent respectivement des assemblées législatives relativement puissantes, représentant un nombre de citoyens conséquent et ayant d’importantes prérogatives constitutionnelles ou institutionnelles en matière commerciale, mais évoluant dans des cadres significativement différents. Via leurs outils institutionnels et à travers des pressions formelles et informelles de la part de ces deux pouvoirs législatifs, les exécutifs se retrouvent souvent contraints de prendre en compte certaines revendications des parlementaires faisant voix aux revendications d’une partie de la société civile. À défaut, le risque de voir une négociation échouer faute de ratification de l’accord par le pouvoir législatif est important. Néanmoins, l’influence du pouvoir législatif n’est pas la même pour chaque négociation et le contexte de celle-ci va dès lors jouer un rôle important pour en déterminer l’amplitude et la visibilité d’une assemblée dans ces différents processus.

Accurate electromagnetic modelling of the head of a subject is of main interest in the fields of source reconstruction and brain stimulation. Those processes rely heavily on the quality of the model and, even though the geometry of the tissues can be extracted from magnetic resonance images (MRI) or computed tomography (CT), their physical properties such as the electrical conductivity are hard to measure with non intrusive techniques. In this paper, we propose a tool to assess the uncertainty in the model parameters as well as compute a parametric electroencephalography (EEG) forward solution and current distribution for transcranial direct current stimulation (tDCS).

Background Cortical excitability changes across conscious states, being higher in unconsciousness compared to normal wakefulness. Anaesthesia offers controlled manipulation to investigate conscious processes and underlying brain dynamics. Among commonly used anaesthetic agents, dexmedetomidine (DEX) effects are not completely known. In this study, we investigated cortical excitability as a function of DEX sedation depth.Methods Transcranial magnetic stimulation coupled with electroencephalography was recorded in 20 healthy subjects undergoing DEX sedation in four conditions (baseline, light sedation, deep sedation, recovery). Frontal and parietal cortices were stimulated using a neuronavigation system. Cortical excitability was inferred by slope, amplitude, positive and negative peak latencies of the first component (0-30 ms) of the TMS-evoked potential. Four Generalized Linear Mixed Models (GLMM) were used to test the effect of condition and brain region over cortical excitability.Results Dexmedetomidine modulated amplitude (P\<0.001), slope (P=0.0001) and positive peak (P=0.042), while the targeted brain region affected amplitude (P\<0.001), slope (P\<0.001), and negative peak (P=0.001). The interaction between dexmedetomidine and region had an effect over amplitude (P=0.004), and slope (P=0.009) such that cortical excitability was higher during all conditions where DEX was present as compared to the baseline.Conclusions Cortical excitability changes non-linearly as a function of the depth of DEX sedation, with a paradoxical non dose-dependent increase. The effect is region-specific, being present in the frontal but not in the parietal region. Future research should extend the current results with other anaesthetics to better understand the link between cortical excitability and depth of sedation.Competing Interest StatementVB declares that he has received a research grant from Orion Pharma and honoraria for consultancy from Medtronic for the past 6 years.

Multi-fingered robotic grasping is an undeniable stepping stone to universal picking and dexterous manipulation. Yet, multi-fingered grippers remain challenging to control because of their rich nonsmooth contact dynamics or because of sensor noise. In this work, we aim to plan hand configurations by performing Bayesian posterior inference through the full stochastic forward simulation of the robot in its environment, hence robustly accounting for many of the uncertainties in the system. While previous methods either relied on simplified surrogates of the likelihood function or attempted to learn to directly predict maximum likelihood estimates, we bring a novel simulation-based approach for full Bayesian inference based on a deep neural network surrogate of the likelihood-to-evidence ratio. Hand configurations are found by directly optimizing through the resulting amortized and differentiable expression for the posterior. The geometry of the configuration space is accounted for by proposing a Riemannian manifold optimization procedure through the neural posterior. Simulation and physical benchmarks demonstrate the high success rate of the procedure. [less ▲]

The distributional reinforcement learning (RL) approach advocates for representing the complete probability distribution of the random return instead of only modelling its expectation. A distributional RL algorithm may be characterised by two main components, namely the representation and parameterisation of the distribution and the probability metric defining the loss. This research considers the unconstrained monotonic neural network (UMNN) architecture, a universal approximator of continuous monotonic functions which is particularly well suited for modelling different representations of a distribution (PDF, CDF, quantile function). This property enables the decoupling of the effect of the function approximator class from that of the probability metric. The paper firstly introduces a methodology for learning different representations of the random return distribution. Secondly, a novel distributional RL algorithm named unconstrained monotonic deep Q-network (UMDQN) is presented. Lastly, in light of this new algorithm, an empirical comparison is performed between three probability quasimetrics, namely the Kullback-Leibler divergence, Cramer distance and Wasserstein distance. The results call for a reconsideration of all probability metrics in distributional RL, which contrasts with the dominance of the Wasserstein distance in recent publications. [less ▲]

Motion during the acquisition of magnetic resonance imaging (MRI) data degrades image quality, hindering our capacity to characterize disease in patient populations. Quality control procedures allow the exclusion of the most affected images from analysis. However, the criterion for exclusion is difficult to determine objectively and exclusion can lead to a suboptimal compromise between image quality and sample size. We provide an alternative, data-driven solution that assigns weights to each image, computed from an index of image quality using restricted maximum likelihood. We illustrate this method through the analysis of brain MRI data. The proposed method restores the validity of statistical tests, and performs near optimally in all brain regions, despite local effects of head motion. This method is amenable to the analysis of a broad type of MRI data and can accommodate any measure of image quality. [less ▲]

What are the determinants of philanthropic and political giving? Are donations to charities and parties driven by the same incentives? In this article, we use new administrative household panel data to quantify empirically the motivations for giving, depending on donors' characteristics and tax incentives. Our dataset includes all the households filling their income tax and/or their wealth tax returns in France between 2006 and 2019. In France, both charitable and political donations benefit from income tax deductions, but only the charitable ones are eligible to the wealth tax credit. We exploit the 2018 wealth tax reform a change in the taxable base that led to a drop by two third in the number of liable households to estimate the cross-price elasticity of charitable and political giving at different levels of the income and wealth distributions. We provide new evidence of substituability between charitable and political donations: according to our estimates, a one-percent increase in the price of charitable giving leads to a 19 to 25 increase in political donations. The magnitude of this effect is particularly strong among the the top 20 of the wealth taxpayers. [less ▲]

Understanding and controlling the transport properties of interacting fermions is a key forefront in quantum physics across a variety of experimental platforms. Motivated by recent experiments in 1D electron channels written on the $\mathrm{LaAlO_3}$/$\mathrm{SrTiO_3}$ interface, we analyse how the presence of different forms of spin-orbit coupling (SOC) can enhance electron pairing in 1D waveguides. We first show how the intrinsic Rashba SOC felt by electrons at interfaces such as $\mathrm{LaAlO_3}$/$\mathrm{SrTiO_3}$ can be reduced when they are confined in 1D. Then, we discuss how SOC can be engineered, and show using a mean-field Hartree-Fock-Bogoliubov model that SOC can generate and enhance spin-singlet and triplet electron pairing. Our results are consistent with two recent sets of experiments [Briggeman et al., arXiv:1912.07164; Sci. Adv. 6, eaba6337 (2020)] that are believed to engineer the forms of SOC investigated in this work, which suggests that metal-oxide heterostructures constitute attractive platforms to control the collective spin of electron bound states. However, our findings could also be applied to other experimental platforms involving spinful fermions with attractive interactions, such as cold atoms. [less ▲]

In this work, first principle calculations of Cu2 ZnSnS4 (CZTS), Cu2 ZnGeS4 (CZGS) and Cu2 ZnSiS4 (CZSS) are performed to highlight the impact of the cationic substitution on the structural, electronic and optical properties of kesterite compounds. Direct bandgaps are reported with values of 1.32, 1.89 and 3.06 eV respectively for CZTS, CZGS and CZSS. In addition, absorption coefficient values of the order of 10^4 cm^{−1} are obtained, indicating the applicability of these materials as absorber layer for solar cell applications. In the second part of this study, ab initio results (absorption coefficient, refractive index and reflectivity) are used as input data to model the electrical power conversion efficiency of kesterite-based solar cell. In that perspective, we used an improved version of the Shockley-Queisser theoretical model including non-radiative recombination via an external parameter defined as the internal quantum efficiency. Based on predicted optimal absorber layer thicknesses, the variation of the solar cell maximal efficiency is studied as a function of the non-radiative recombination rate. Maximal efficiencies of 25.88 %, 19.94 % and 3.11 % are reported respectively for Cu2ZnSnS4, Cu2ZnGeS4 and Cu2ZnSiS4 for vanishing non-radiative recombination rate. Using a realistic internal quantum efficiency which provides 𝑉OC values comparable to experimental measurements, solar cell efficiencies of 15.88, 14.98 and 2.66 % are reported respectively for Cu2ZnSnS4, Cu2ZnGeS4 and Cu2ZnSiS4 (for an optimal thickness of 1.15 𝜇m). With this methodology we confirm the suitability of Cu2ZnSnS4 in single junction solar cells, with a possible efficiency improvement of 10% enabled through the reduction of the non-radiative recombination rate. In addition, Cu2ZnGeS4 appears to be an interesting candidate as top cell absorber layer for tandem approaches whereas Cu2ZnSiS4 might be interesting for transparent photovoltaic windows. [less ▲]

To combat climate change, governments are taking an increasing number of technology-specific measures to support green technologies. In this paper, we look at the very generous subsidy policies to solar PVs in the three regions of Belgium to ask the question of how voters responded to these programs. We provide evidence that voters did not reward the incumbent government that was responsible for the program, as predicted by the ‘buying-votes’ hypothesis. Instead, we find that voters punish the incumbent government because of the increasing awareness of the high financing costs. These did not only affectt he non-adopting electricity consumers who did not benefit from the programs, but also the adopting prosumers, who saw unannounced new costs such as the introduction of prosumer fees to get access to the grid.

Everybody is talking about Open Science and FAIR data but can you really make a living (and a good career) out of it? Will my career get better if I FAIRify my data? Or will it just make my head ache? When someone will evaluate my research, will the fact that my data complies with all the Open Science best practices matter? Or am I just losing time I should rather spend publishing on whatever journal I can lay hands on? And where am I supposed to learn how to be fair and open anyway? The right answer to these questions is crucial to the career choices and expectations of many students and young researchers, yes, but it is also the point which can make the difference between succeeding or failing in establishing Open Science (and ultimately Good Science). To be able to shift the research evaluation system in Europe in order to produce quality and reliable data, to set up a working incentive system for individual researchers and organisations is one of the keys to a widespread uptake of Open Science and FAIR practices. And being so crucial a point, we believe that researchers, Research Infrastructures, scientific organisations should have a say in this. That’s why we proposed an interactive session where good ideas, innovative pilots, proposed policies from all across Europe were presented and discussed. [less ▲]

This paper introduces a methodology to perform an ex-post allocation of locally generated electricity among the members of a renewable energy community. Such an ex-post allocation takes place in a settlement phase where the financial exchanges of the community are based on the production and consumption profiles of each member. The proposed methodology consists of an optimisation framework which (i) minimises the sum of individual electricity costs of the community members, and (ii) can enforce minimum self-sufficiency rates –proportion of electricity consumption covered by local production– on each member, enhancing the economic gains of some of them. The latter capability aims to ensure that members receive enough incentives to participate in the renewable energy community. This framework is designed so as to provide a practical approach that is ready to use by community managers, which is compliant with current legislation on renewable energy communities. It computes a set of optimal repartition keys, which represent the percentage of total local production given to each member – one key per metering period per member. These keys are computed based on an initial set of keys provided in the simulation, which are typically contractual i.e., agreed upon between the member and the manager the renewable energy community. This methodology is tested in a broad range of scenarios, illustrating its ability to optimise the operational costs of a renewable energy community. [less ▲]

The novel Coronavirus (COVID-19) impacted daily life for residents of the majority of countries worldwide. In this this research note, we explore how the pandemic is changing religious-oriented shopping with a focus on Muslim shopping. While supermarkets provided online shopping and home delivery services, Islamic store, as small business, could not opt for such services in Belgium and many other countries. Therefore, we designed and conducted a consumer survey with a special target of Muslim shoppers between April 27 and May 6 2020 in all Belgium regions. We found that despite stay-at-home directives that is effective since early March 2020, Muslims are still leaving their homes to buy Islamic groceries “Halal”. Most importantly, the daily pattern of shopping has significantly been changed, which helped in reducing the density of shoppers in the stores [less ▲]

The numerous stakeholders involved in the development of universal health coverage (UHC) policies are likely to have diverging interests about which dimensions to prioritize, hence the importance of ensuring an effective and transparent policy dialogue. This paper aims to investigate whether or not UHC policy dialogue processes are functioning well in Benin and Senegal. Based on a literature review, we have identified a number of characteristics guaranteeing the quality of policy dialogue processes, which we have integrated into an analytical grid. The quality criteria identified were classified along four dimensions: stakeholder participation, dialogue/negotiation process, quality of situation analysis and decision criteria, and results from the negotiation process. Based on data collected through documentary review, interviews, an electronic survey and the authors’ own experience, we applied that analytical grid to the cases of Benin and Senegal. In both countries, the policy dialogue processes are largely imperfect in terms of many of the quality criteria identified. Decisions were made under strong political leadership, ensuring government coordination and ownership, and strong emphasis has been put on expanding financial risk protection. Yet, both countries perform poorly in a number of dimensions, especially with regards to conflicts of interest, transparency and accountability. None of them has really institutionalized a UHC policy dialogue process, and the UHC policymaking processes have actually bypassed existing health sector coordination mechanisms. The two countries perform well regarding the quality of situation analysis. A small (in the case of Benin) or broader (in the case of Senegal) governmental coalition managed to impose its views, given insufficient stakeholder participation. Policy networks were particularly influential in Senegal. Overall, there are important gaps that reduce the quality of UHC policy dialogue processes, hence explaining the weaknesses in their results in terms of transparency and accountability. Our analytical framework enables us to identify rooms for improvement with regard to country-led negotiation processes relating to UHC. [less ▲]

Coupled problems result in very stiff problems whose char- acteristic parameters differ with several orders in magni- tude. For such complex problems, solving them monolith- ically becomes prohibitive. Since nowadays there are op- timized solvers for particular problems, solving uncoupled problems becomes easy since each can be solved indepen- dently with its dedicated optimized tools. Therefore the co-simulation of the sub-problems solvers is encouraged. The design of the transmission coupling conditions between solvers plays a fundamental role. The current paper applies the waveform relaxation methods for co-simulation of the finite element and circuit solvers, investigate the contribu- tion of higher order integration methods and also consid- ers the the theoretical modelling of a boost converter. The method is illustrated on a coupled finite element inductor and a boost converter and focuses on the comparison of the transmission coupling conditions based on the waveform iteration numbers between the two sub-solvers. We demon- strate that for lightly coupled systems the dynamic itera- tions between the sub-solvers depends much on the inter- nal integrators in individual sub-solvers whereas for tightly coupled systems it depends also to the kind of transmission coupling conditions.
