Collaborative Infrastructure – Data Stewards and the Base4NFDI Service Ecosystem
No full textThis Poster presented at the 'Data Stewardship goes Germany 2025' is basis for an interactive dialogue between Data stewards and Service stewards of Base4NFDI. It presents 5 of the available basic services which might be most valuable for data stewards and gives the possibility to give own opinions and input through post it's, which can put on the poster. The second page is the input from participents of the conference. AbstractThe German National Research Data Infrastructure (NFDI) initiative Base4NFDI addresses interdisciplinary challenges in research data management by supporting the development and integration of cross-domain basic services. This poster introduces a selection of Base4NFDI services and highlights the pivotal role data stewards play as stakeholders, contributors, and multipliers in their development and adoption. It also illustrates how basic services support data stewards and other RDM professionals in their role. Data stewards bridge domain-specific requirements and technical implementation, making them critical stakeholders in basic service development adoption. During basic service development, they can contribute their requirements to tailor services to their target groups’ needs. In the integration phase, which is the second of three stages of service development focusing on integrating basic services broadly into NFDI consortia, they may facilitate service-related training and advocate for institutional buy-in. Base4NFDI is developing a growing portfolio of basic services at various stages of maturity. The following selection presents key services that are already in use and particularly relevant for data stewards, as they are community-developed, cross-disciplinary, and directly support the work of RDM professionals and researchers. Jupyter4NFDI provides a centralized JupyterHub and democratizes access to computational infrastructure via Jupyter notebooks. Thereby it fosters reproducible, FAIR digital research workflows. Data stewards are users and multipliers of this service. They help researchers adopt the platform, show how it can be used for workshops or may provide RDM training and resources via Jupyter notebooks. IAM4NFDI delivers a state-of-the-art identity and access management system, enabling users to login to NFDI services with their home organizations account. Data stewards can point resource providers to potential integrations with IAM4NFDI solutions, facilitate access to virtual organisations for researchers where appropriate, and communicate user needs to service developers. TS4NFDI offers widgets for terminologies, supporting harmonization and curation across disciplines. Its Terminology Service Suite (TSS) provides a collection of interactive widgets that ease the integration of terminology service functions into user applications. This makes it easier for data stewards to promote metadata provision, quality and interoperability within their communities. DMP4NFDI standardizes and streamlines the creation and management of data management plans (DMPs) and software management plans (SMPs) using the open-source RDMO tool. It coordinates template creation, offers guidance, training and support, directly empowering data stewards in their advisory and quality assurance roles. RDMTraining4NFDI assembles a modular collection of RDM training materials and supports the development of community-specific adaptations. Data stewards are both contributors to and primary users of these train-the-trainer resources, helping to disseminate best practices and foster a culture of data literacy. By actively engaging with these services - through co-development, feedback, training, and advocacy - data stewards can help shape solutions that are not only technically sound but also aligned with the practical needs of their research community. With their involvement they can directly influence tools and standards that support their daily work, making them more usable, interoperable, and sustainable. Contributing in this way not only enhances their professional expertise and network but also reinforces their role as a key enabler of FAIR data practices. To engage, data stewards and other RDM professionals can join NFDI sections and consortia or simply contact Base4NFDI’s Service Stewards who consolidate technical and community requirements. The 2025 Data Stewardship conference in Karlsruhe provides a platform to discuss these dynamics, emphasizing use cases in interoperability, tool integration, and reproducibility
Directive-based GPU programming with OpenACC
No full textGPU-accelerated computing drives current scientific research. Writing fast numeric algorithms for GPUs offers high application performance by offloading compute-intensive portions of the code to the GPU. The course will cover basic aspects of GPU architectures and programming. Focus is on the usage of the directive-based OpenACC programming model which allows for portable application development. Examples of increasing complexity will be used to demonstrate optimization and tuning of scientific applications

From Impedance to Harmonics: A Dual-Diagnostic Approach for SOC Stack Degradation Assessment in Co-Electrolysis Mode
No full textHigh-temperature solid oxide cell (SOC) stacks enable co-electrolysis of H2O and CO2 into H2 and CO, providing an efficient pathway toward sustainable, carbon-neutral fuel cycles. However, SOC stacks still face degradation challenges that hinder their broad industrial implementation, particularly at high gas conversion ratios and elevated current densities. Early detection of these degradation mechanisms—using diagnostic methods such as Total Harmonic Distortion (THD)—is essential to prevent irreversible damage and extend stack lifetime
Survey on the use of tenability criteria in CFD analyses for Performance-Based Fire Safety Engineering
No full textAn online survey on the use of tenability criteria in CFD analyses for PBFSE was conducted, to better understand the current industry practices in fire modelling. 254 participants responded, representing wide range of roles in professional practice. Visibility in smoke is the most used (90.2%) and most influential (91.4%) tenability criterion, while smoke temperatures are being commonly evaluated (76.5%) but more rarely impact the design (45.8%). Criteria related to smoke toxicity were used only by 10.4% - 19.9% of participants, indicating potential gaps in life safety assessments. The paper presents more detailed results, as well as future research directions informed by the outcomes
