A research data management (RDM) community for ELIXIR
No full textResearch data management (RDM) is central to the implementation of the FAIR (Findable Accessible, Interoperable, Reusable) and Open Science principles. Recognising the importance of RDM, ELIXIR Platforms and Nodes have invested in RDM and launched various
projects and initiatives to ensure good data management practices for scientific excellence. These projects have resulted in a rich set of tools and resources highly valuable for FAIR data management. However, these resources remain scattered across projects and ELIXIR structures, making their dissemination and application challenging.
Therefore, it becomes imminent to coordinate these efforts for sustainable and harmonised RDM practices with dedicated forums for RDM professionals to exchange knowledge and share resources.
The proposed ELIXIR RDM Community will bring together RDM experts to develop ELIXIR’s vision and coordinate its activities, taking advantage of the available assets. It aims to coordinate RDM best
practices and illustrate how to use the existing ELIXIR RDM services.
The Community will be built around three integral pillars, namely, a network of RDM professionals, RDM knowledge management and RDM training expertise and resources. It will also engage with external stakeholders to leverage benefits and provide a forum to RDM professionals for regular knowledge exchange, capacity building and development of harmonised RDM practices, keeping in line with the overall scope of the RDM Community.
In the short term, the Community aims to build upon the existing resources and ensure that the content of these remain up to date and fit for purpose. In the long run, the Community will aim to strengthen the skills and knowledge of its RDM professionals to support the
emerging needs of the scientific community. The Community will also devise an effective strategy to engage with other ELIXIR structures and international stakeholders to influence and align with developments and solutions in the RDM field
Reducing antenna leakage in quasi-monostatic satellite radar using planar metamaterials
No full textIn an autonomous robotic space debris removal mission, an essential sensor used for navigation is an FMCW radar designed for close-range relative navigation. To achieve the required range performance, minimizing RF leakage between the transmitter (Tx) and receiver (Rx) antennas is essential for the accurate detection of the range and velocity of the targeted space debris. Antennas positioned above the metallic satellite front face are highly susceptible to RF leakage, primarily caused by surface current propagation and lateral waves traveling parallel to the platform. This study presents two lightweight, single-layer planar metamaterials—a novel compact electromagnetic bandgap (EBG) and a non-uniform high-impedance surface (HIS)—optimized to suppress both surface waves and interact with space waves within the 9.3–9.8 GHz frequency range. These designs address strict size, weight, and power (SWaP) constraints while ensuring compatibility with extreme space conditions and resistance to mechanical shocks. Experimental validation indicates that a minimum Tx/Rx isolation improvement of 10 dB is achieved using the HIS, and 20 dB is achieved using the EBG across the radar’s operational bandwidth (5%)
La valorisation, une étape comme une autre du processus itératif de recherche ?
No full textDans ce texte, la valorisation de la recherche est abordée non pas en tant que présentation d’un output figé, mais en tant qu’étape du processus de recherche soumise à l’expertise du public composé de personnes concernées, de personnes professionnelles et de la communauté de chercheuses et chercheurs. Le texte comprend tout d’abord un historique récapitulant l’évolution des diverses formes de valorisation de la recherche. Il décrit par la suite ce qui est entendu par « la valorisation en tant qu’étape du processus itératif de recherche » et propose une mise en contexte théorique de l’appropriation par toutes et tous de l’objet de la recherche. Une réflexion sur les bénéfices et défis de ce type de valorisation, tels que le rôle et la posture de chacune et chacun, la planification de la phase de valorisation, la co-construction, la reconnaissance des idées et autres est menée. Le texte se termine par une illustration de la théorie à partir des expériences de valorisation du projet « Ma santé : je m’informe et je choisis » réalisé dans le cadre du programme Innovation Booster Technologie et Handicap (IBTH)
Optimizing a 2D active set-up for global control of low-frequency wall reflections in a semi-anechoic room
No full textNumerical simulations were carried out to optimize the design of an active semi-anechoic room. The active set-up includes control sources and microphones near the room ceiling and walls. The objective is to achieve global control, around an a priori unknown primary source, of the low-frequency wall reflections that are not adequately managed by absorbing material. The control strategy is based on the estimation, by linear filtering of total pressure signals, of the scattered pressure at minimization points meshing the room ceiling and walls. The required filters are identified off-line from measurements with a source whose radiation pattern is known. A 2D simple modal model is used to simulate active control in the frequency domain. The location of the minimization points, the set of estimation microphones and the method for computing the control signals from the measurements are varied. Simulations show that i) efficient global control of the scattered pressure can be achieved over a wide frequency band with a single non-smooth layer of minimization points, ii) accurate scattered pressure estimation at the minimization points can be achieved using usual pressure microphones distributed over all walls, iii) a Remote-Microphone technique seems slightly preferable to an Additional-Filter method for calculating the control signals
Évaluation du positionnement optimal d’un accéléromètre pour mesurer la durée et le type d’activité physique ::une étude préliminaire
No full textContexte : L’évaluation de l’activité physique est essentielle pour le suivi des personnes en réadaptation. Les capteurs de mouvement embarqués offrent une alternative intéressante aux questionnaires habituellement utilisés en pratique clinique. Objectif : Cette étude vise à évaluer la capacité d’un accéléromètre unique, placé sur différentes structures corporelles, à mesurer la durée et le type d’activité physique afin de déterminer le positionnement optimal de cet outil pour ces mesures. Méthodes : Deux participants ont effectué trois activités avec des accéléromètres positionnés sur leur hanche, leur cuisse et leur poignet. Les données d’accélération ont été analysées avec une méthode de classification basée sur le calcul de seuils optimaux moyens à partir de courbes ROC (Receiver Operating Characteristic). Puis la sensibilité et la spécificité de chaque capteur ont été calculées pour chaque participant. Résultats : Les accéléromètres positionnés sur la hanche, la cuisse et le poignet permettent de différencier le temps d’activité physique et de comportement sédentaire avec une probabilité de 72 à 87 %. Dans les périodes d’activité physique, les accéléromètres positionnés sur la hanche et la cuisse permettent de différencier le temps de marche et d’activité debout avec une probabilité de 82 à 91 % alors que l’accéléromètre positionné au poignet permet de différencier ces mêmes types d’activité avec une probabilité de 55 à 68 %. Conclusion : Un accéléromètre positionné sur le poignet peut être utilisé pour mesurer le temps d’activité physique et de comportement sédentaire alors que d’autres localisations telles que la hanche ou la cuisse sont à privilégier pour évaluer plus précisément le type d’activité réalisé.Evaluating the optimal positioning of an accelerometer for measuring the duration and type of physical activity : a preliminary study. Introduction: Assessment of physical activity is crucial in rehabilitation. Wearable motion sensors are an appealing alternative to the questionnaires commonly used in clinical practice. Objective: This study aimed to assess the ability of a single accelerometer placed on different body parts to measure the duration and type of physical activity to determine the optimal placement of this device for these measurements. Methods: Two participants performed three tasks with three accelerometers simultaneously positioned on their hip, thigh, and wrist. Acceleration data were processed using a classification method based on the calculation of optimal thresholds using the receiver operating characteristic (ROC) curves. Then, the sensitivity and specificity of each sensor were calculated for each participant. Results: Accelerometers on the hip, thigh, and wrist differentiated between physical activity and sedentary behavior time with an accuracy of 72%–87%. During periods of physical activity, accelerometers on the hip and thigh differentiated walking and standing time with an accuracy of 82%–91%, whereas the wrist accelerometer distinguished the same types of activity with an accuracy of 55%–68%. Conclusions: A wrist-worn accelerometer can be used to measure physical activity time versus sedentary time, whereas other placements such as the hip or thigh are preferable for a more precise assessment of the type of activity performed.Bewertung der optimalen Positionierung eines Beschleunigungsmessers zur Messung von Dauer und Art der täglichen körperlichen Aktivität : eine vorläufige Studie. Hintergrund: Die Bewertung der körperlichen Aktivität ist entscheidend für die Überwachung von Personen in der Rehabilitation. Tragbare Bewegungssensoren bieten eine interessante Alternative zu den in der klinischen Praxis üblicherweise verwendeten Fragebögen. Ziel: Das Ziel dieser Studie ist es, die Fähigkeit eines einzelnen Beschleunigungsmessers zur Erfassung der Dauer und Art der körperlichen Aktivität, der an verschiedenen Körperstellen platziert wird, zu bewerten, um die optimale Positionierung dieses Geräts für diese Messungen zu bestimmen. Methode: Zwei Teilnehmer führten drei Aufgaben mit an der Hüfte, dem Oberschenkel und dem Handgelenk angebrachten Beschleunigungsmessern aus. Die Beschleunigungsdaten wurden mittels einer Klassifizierungsmethode analysiert, die auf der Berechnung durchschnittlicher optimaler Schwellenwerte aus Receiver-Operating-Characteristic- Kurven basiert. Anschließend wurden Sensitivität und Spezifität jedes Sensors für jeden Teilnehmer errechnet. Ergebnisse: Die Beschleunigungsmesser an Hüfte, Oberschenkel und Handgelenk messen die Dauer der körperlichen Aktivität und des sitzenden Verhaltens mit einer Wahrscheinlichkeit von 72 bis 87%. In Phasen körperlicher Aktivität prognostizieren die Geräte an Hüfte und Oberschenkel die Geh- und Stehzeiten mit einer Wahrscheinlichkeit von 82 bis 91%, während der Beschleunigungsmesser am Handgelenk dieselben Aktivitätsarten mit einer Wahrscheinlichkeit von 55 bis 68% vorhersagt. Schlussfolgerung: Ein am Handgelenk positionierter Beschleunigungsmesser kann verwendet werden, um die Dauer der körperlichen Aktivität und des sitzenden Verhaltens zu messen, während andere Positionen wie an der Hüfte oder dem Oberschenkel genutzt werden sollten, um die Art der ausgeführten Aktivität zu bewerten
Pushbacks, border deaths and the right to life ::the recent case law of the European Court of Human Rights
No full textFaced with restrictive border policies, third-country nationals are increasingly turning to the European Court of Human Rights to protect their lives. Until recently, Article 2 of the European Convention on Human Rights has not been much pronounced upon in the Court’s asylum and migration jurisprudence. However, its three recent judgments concerning pushbacks and border deaths M.H. and Others v. Croatia, Safi and Others v. Greece and Alhowais v. Hungary, advance the Court’s case law on the right to life. This article scrutinises the Court’s overall strong response to national pushback practices carrying life-threatening risks

No full textContext
Contemporary technologies, such as mainstream and specialised Assistive Technologies (ATs), are seen as effective. However, there is a noticeable gap between technological progress and the ability to customise these technologies to meet the unique needs and characteristics of neurodivergent individuals, particularly those on the Autism Spectrum and people with Intellectual Disability (pwID).
Purpose
The goal of this study is to investigate the present requirements and future priorities acknowledged by specialists in the field regarding the progress of social inclusion for this population, making use of ATs.
Methods and results
A qualitative survey involving 24 international experts, and its respective thematic analysis reveals challenges in social inclusion, emphasizing communication and physical accessibility, awareness gaps, and stigma. Concurrently, issues surrounding ATs include limited access, insufficient training, and a lack of awareness and skills, with individuals, and families being inadequately involved.
Conclusion and implications
The study proposes strategies for overcoming these challenges, with a focus on accessibility, awareness, skills, family involvement, and customization. Identified research needs encompass scientific development, inclusive approaches, and changes in technological development paradigms
