The main aim of the paper is to characterize the proposed model of risk management system. Threats identification and risk assessment of the systemic character result in taking action directed on risk elimination, minimization or financing. Concept of the risk management system includes the following anti-risk activities concerning: knowledge, operating, experience and improvement. Those risk actions guarantee effective manner of risk management, which is of particular meaning due to the difficult situation of the European Union's steel industry facing geopolitical, economic and environmental challenges. The model in question can be treated as a guidelines for proceeding in case of prevention and response to the potential, both strategic and operational, metallurgical risk.
PowerDynamics.jl is a Julia package for time-domain modeling of power grids that is specifically designed for the stability analysis of systems with high shares of renewable energies. It makes use of Julia's state-of-the-art differential equation solvers and is highly performant even for systems with a large number of components. Further, it is compatible with Julia's machine learning libraries and allows for the utilization of these methods for dynamical optimization and parameter fitting. The package comes with a number of predefined models for synchronous machines, transmission lines and inverter systems. However, the strict open-source approach and a macro-based user-interface also allows for an easy implementation of custom-built models which makes it especially interesting for the design and testing of new control strategies for distributed generation units. This paper presents how the modeling concept, implemented component models and fault scenarios have been experimentally tested against measurements in the microgrid lab of TECNALIA. ; This research has been performed using the ERIGrid Research Infrastructure and is part of a project that has received funding from the European Union's Horizon 2020 Research and Innova-tion Programme under the Grant Agreement No. 654113. The support of the European Research Infrastructure ERIGrid and its partner TECNALIA is very much appreciated.

Medical artificial intelligence (AI) systems have been remarkably successful, even outperforming human performance at certain tasks. There is no doubt that AI is important to improve human health in many ways and will disrupt various medical workflows in the future. Using AI to solve problems in medicine beyond the lab, in routine environments, we need to do more than to just improve the performance of existing AI methods. Robust AI solutions must be able to cope with imprecision, missing and incorrect information, and explain both the result and the process of how it was obtained to a medical expert. Using conceptual knowledge as a guiding model of reality can help to develop more robust, explainable, and less biased machine learning models that can ideally learn from less data. Achieving these goals will require an orchestrated effort that combines three complementary Frontier Research Areas: (1) Complex Networks and their Inference, (2) Graph causal models and counterfactuals, and (3) Verification and Explainability methods. The goal of this paper is to describe these three areas from a unified view and to motivate how information fusion in a comprehensive and integrative manner can not only help bring these three areas together, but also have a transformative role by bridging the gap between research and practical applications in the context of future trustworthy medical AI. This makes it imperative to include ethical and legal aspects as a cross-cutting discipline, because all future solutions must not only be ethically responsible, but also legally compliant. ; Andreas Holzinger acknowledges funding support from the Austrian Science Fund (FWF), Project: P-32554 explainable Artificial Intelligenceand from the European Union's Horizon 2020 research and innovationprogram under grant agreement 826078 (Feature Cloud).

The domestic and international transmission mechanism of fiscal policy shocks are analysed in the United States and in Germany. Using a Bayesian VAR approach, we find that in both of these countries a fiscal expansion is associated with increases in output as well as in private consumption and investment. The terms of trade, which affect the international transmission of fiscal policy shocks, depreciate in response to a fiscal expansion, thus transferring some of the increased domestic purchasing power abroad. A US government spending shock is expansionary for all non-US G7 members. A German government spending shock is expansionary for most, but not all European economies, both within and outside the euro area. The dynamics of the BVAR can be rationalised using a dynamic stochastic general equilibrium model where heterogeneous households and firms face borrowing constraints.
We present a mathematical model to study the steady-state performance of a membrane-less reversible redox flow battery formed by two immiscible electrolytes that spontaneously form a liquid-liquid system separated by a well defined interface. The model assumes a two-dimensional battery with two coflowing electrolytes and flat electrodes at the channel walls. In this configuration, the analysis of the far downstream solution indicates that the interface remains stable in all the parameter range covered by this study. To simplify the description of the problem, we use the dilute solution theory to decouple the calculation of the velocity and species concentration fields. Once the velocity field is known, we obtain the distribution of the mobile ionic species along with the current and the electric potential field of the flowing electrolyte solution. The numerical integration of the problem provides the variation of the battery current density Iapp with the State of Charge (SoC) for different applied cell voltages Vcell. A detailed analysis of the concentration density plots indicates that the normal operation of the battery is interrupted when reactant depletion is achieved near the negative electrode both during charge and discharge. The effect of the electrolyte flow on the performance of the system is studied by varying the Reynolds, Re and Péclet, Pe, numbers. As expected, the flow velocity only affects the polarization curve in the concentration polarization region, when is well below the equilibrium potential, resulting in limiting current densities that grow with Re. ; This work has been partially funded by the Spanish Agencia Estatal de Investigación under projects (PID2019-106740RB- I00 and PID2019-108592RB-C41/AEI/10.13039/50110 0 011033), by Grant IND2019/AMB-17273 of the Comunidad de Madrid and by project MFreeB which have received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (Grant Agreement No. 726217).

Defence date: 26 January 2021 ; Examining board: Professor Regina Grafe (European University Institute); Professor Luca Molà (University of Warwick); Professor Carmen Sanz Ayán (Universidad Complutense de Madrid); Professor Manuel Herrero Sánchez (Universidad Pablo de Olavide) ; This doctoral thesis analyses the process of state construction in the early modern period from a joint perspective that amalgamates the agencies of state officials, lending communities, and local elites in the Hispanic Monarchy during the four initial years of Philip II's reign. The project examines the convergence of private agendas inside and outside the royal administration, which were channelled by the Genoese lending community to overcome the consolidation of royal short-term debt in 1557 and its consequences. The application of an institutional approach, based on the works of Avner Greif, to the analysis of the social organisations that prevented a failure of coordination in the Hispanic Monarchy offers a fresh perspective on a topic normally assessed under predatory models. The specific study of two Genoese lenders who contributed to the establishment of a more viable and efficient financial system in the monarchy, Costantin Gentil and Nicolao de Grimaldo, provides details about how interregional transactions and local economies contributed to the consolidation of the early modern state.
Endocrine disrupting chemicals (EDCs) are ubiquitous in the environment and involve diverse chemical-receptor interactions that can perturb hormone signaling. The Organization for Economic Co-operation and Development has validated several EDC-receptor bioassays to detect endocrine active chemicals and has established guidelines for regulatory testing of EDCs. Focus on testing over the past decade has been initially directed to EATS modalities (estrogen, androgen, thyroid, and steroidogenesis) and validated tests for chemicals that exert effects through non-EATS modalities are less established. Due to recognition that EDCs are vast in their mechanisms of action, novel bioassays are needed to capture the full scope of activity. Here, we highlight the need for validated assays that detect non-EATS modalities and discuss major international efforts underway to develop such tools for regulatory purposes, focusing on non-EATS modalities of high concern (i.e., retinoic acid, aryl hydrocarbon receptor, peroxisome proliferator-activated receptor, and glucocorticoid signaling). Two case studies are presented with strong evidence amongst animals and human studies for non-EATS disruption and associations with wildlife and human disease. This includes metabolic syndrome and insulin signaling (case study 1) and chemicals that impact the cardiovascular system (case study 2). This is relevant as obesity and cardiovascular disease represent two of the most significant health-related crises of our time. Lastly, emerging topics related to EDCs are discussed, including recognition of crosstalk between the EATS and non-EATS axis, complex mixtures containing a variety of EDCs, adverse outcome pathways for chemicals acting through non-EATS mechanisms, and novel models for testing chemicals. Recommendations and considerations for evaluating non-EATS modalities are proposed. Moving forward, improved understanding of the non-EATS modalities will lead to integrated testing strategies that can be used in regulatory bodies to protect environmental, animal, and human health from harmful environmental chemicals. ; LNM was supported by a H2020-Marie Skłodowska-Curie Action MSCA-IF-RI- 2017 awarded by the European Commission (ref. 797725-EpiSTOX).

The present research aims to analyse the phenomenon of unaccompanied minors arriving from Morocco to the European Union from 2010 to 2021. This recent migratory phenomenon supposes an emerging challenge for governments, international organisations, and societies, in order to guarantee the protection of children according the UN Convention on the Rights of the Child (UN, 1989). The research focuses on the children «on the move», travelling alone from Morocco and arriving in Spain through the Strait of Gibraltar. The so-called Western Mediterranean Migratory Route has become one of the gateways to Europe. Spain hosts nowadays a big community of Moroccan unaccompanied minors and Catalonia has become the second Spanish Autonomous Community with a major number of unaccompanied minors, only surpassed by the enclave of Melilla located on the very border of Morocco. The present research gives special attention to the study of the Amazigh Nationalism question, as something to look at among the reasons why Moroccan unaccompanied minors migrate to Europe, choosing, particularly, Catalonia as a model to pursuit an Amazigh nation. ; A presente pesquisa tem como objetivo analisar o fenómeno da chegada de menores não acompanhados provenientes de Marrocos à União Europeia entre 2010 a 2021. Este fenómeno migratório recente supõe um desafio emergente para governos, organizações internacionais e sociedade para garantir a proteção de crianças segundo a Convenção das Nações Unidas sobre os Direitos da Criança (ONU, 1989). A pesquisa centra-se nas crianças em trânsito que vêm sozinhas de Marrocos e chegam à Espanha pelo Estreito de Gibraltar. A chamada Rota Migratória do Mediterrâneo Ocidental tornou-se uma das portas de entrada para a Europa. Por seu lado, a Espanha acolhe hoje uma grande comunidade de menores não acompanhados marroquinos e, em particular, a Catalunha tornou-se a segunda Comunidade Autónoma Espanhola com maior número de menores não acompanhados, apenas superada por Melilla localizada na fronteira de Marrocos.
