This paper investigates how professionals in German organisations interpret cyber resilience within the software development lifecycle and how socio-technical factors influence its implementation. Drawing on the MITRE Cyber Resiliency Engineering Framework for data collection and coding on Socio-Technical Systems as an interpretive lens, the study adopts a qualitative approach based on semi-structured interviews with 14 professionals across five organisations. The findings reveal a pronounced socio-technical imbalance: while technical measures centred on anticipate and withstand are comparatively established, the corresponding social factors – shared understanding, dedicated responsibility structures, and systematic learning – remain underdeveloped. These conditions are compounded by resource constraints and the absence of strategic prioritisation. Six exploratory hypotheses capture these patterns and offer empirically grounded starting points for future research on product-level cyber resilience.}}, author = {{Taaibi, Samira and Kahraman, Emanuel and Berg, Kevin and Dziwok, Stefan}}, booktitle = {{ECIS 2026 Proceedings}}, keywords = {{Cyber Resilience, Software Development Lifecycle, Qualitative Study, Cyber Resiliency Engineering Framework}}, location = {{Milan, Italy}}, title = {{{Beyond Security: A Qualitative Study of Cyber Resilience Across the Software Development Lifecycle in German Organisations}}}, year = {{2026}}, } @inbook{65930, author = {{Peine, Sara}}, booktitle = {{Wasser Wesen Wandel.

Exergaming offers a promising prophylactic intervention combining physical and cognitive training. The aim of the present study was to assess how exergaming alters the temporal trajectory of brain signal complexity at rest and during gameplay in older adults. Methods Twenty-eight healthy older adults participated in a 4-week exergaming intervention. Electroencephalography was recorded using 64 electrodes at rest (pre- and post-intervention) and during exergaming (pre-, mid-, and post-intervention). Brain signal complexity was quantified using multiscale entropy across 64 time scales on preprocessed signals. Results Post-intervention resting-state analysis revealed significant reductions at fine and increases at coarse scales in frontal, central, and posterior entropy. During gameplay, entropy declined widespread by mid-intervention, particularly at coarse scales over frontal, central and temporal regions. From mid- to post-intervention, the decline narrowed leaving a net pre-to-post reduction concentrated at coarse scales in these regions. Discussion Resting-state changes indicated a shift toward a younger brain profile, characterized by a transition from age-related increases in local processing to enhanced distributed processing, which may potentially mitigate the rise in neural modularity associated with aging. During gameplay, brain signal complexity decreased in week 2, followed by a modest change by week 4, consistent with the framework in which complexity initially streamlines and then adjusts toward a task-specific optimum. These findings suggest that exergaming can beneficially modulate brain complexity in older adults, offering the potential to reduce age-related neural decline and support healthy brain aging. }}, author = {{Piskin, Daghan Yüksel and Müller, Helen Martha and Skjæret-Maroni, Nina and Vereijken, Beatrix and Baumeister, Jochen}}, issn = {{1663-4365}}, journal = {{Frontiers in Aging Neuroscience}}, publisher = {{Frontiers Media SA}}, title = {{{Rewiring the aging brain: exergaming modulates brain complexity in older adults}}}, doi = {{10.3389/fnagi.2025.1748274}}, volume = {{17}}, year = {{2026}}, } @article{65922, abstract = {{Abstract A fundamental equation of state for tetramethoxysilane (TMOS) is developed based on the available experimental data.

As a result, proving QMA-hardness of approximation for ground state energy estimation has remained elusive. Recently, it was shown [Bittel, Gharibian, Kliesch, CCC 2023] that a natural problem involving variational quantum circuits is QCMA-hard to approximate within ratio N^(1-eps) for any eps > 0 and N the input size. Unfortunately, this problem was not related to quantum CSPs, leaving the question of hardness of approximation for quantum CSPs open. In this work, we show that if instead of focusing on ground state energies, one considers computing properties of the ground space, QCMA-hardness of computing ground space properties can be shown. In particular, we show that it is (1) QCMA-complete within ratio N^(1-eps) to approximate the Ground State Connectivity problem (GSCON), and (2) QCMA-hard within the same ratio to estimate the amount of entanglement of a local Hamiltonian's ground state, denoted Ground State Entanglement (GSE). As a bonus, a simplification of our construction yields NP-completeness of approximation for a natural k-SAT reconfiguration problem, to be contrasted with the recent PCP-based PSPACE hardness of approximation results for a different definition of k-SAT reconfiguration [Karthik C.S. and Manurangsi, 2023, and Hirahara, Ohsaka, STOC 2024].}}, author = {{Gharibian, Sevag and Hecht, Carsten}}, booktitle = {{51st International Symposium on Mathematical Foundations of Computer Science (MFCS)}}, title = {{{Hardness of approximation for ground state problems}}}, year = {{2026}}, } @techreport{65789, author = {{Rohlfing, Katharina J. and Steinhardt, Isabel and Scharlau, Ingrid and Schaper, Niclas and Holtfreter, Susan and Biere, Lea and Grimminger, Angela and Schmidt, Rebecca and Festner, Dagmar Franziska and Schmidt, Rebekka and Buhl, Heike M. and Mindt, Ilka and Karsten, Andrea Ramona and Neiske, Iris and Luft, Sebastian}}, title = {{{(Nicht)Nutzung von KI-Werkzeugen in der Lehre: ein Reflexionspapier}}}, doi = {{10.17619/UNIPB/1-2576}}, year = {{2026}}, } @inbook{65912, author = {{Vogelsang, Christoph and Riese, Josef}}, booktitle = {{Handlungsorientierung in der Ausbildung von Lehrkräften und pädagogischen Fachkräften.

Private households are central to this transition, combining dynamic consumption with decentralised generation. This paper presents a multi-agent microgrid simulation built on the Mesa framework, focusing on the heterogeneous objectives and technological capabilities of residential participants. Households are modelled as autonomous agents with individual strategies, while a dedicated “grid agent” represents the distribution system operator and regulates the microgrid in a grid-supportive manner. The emission factor serves as the key indicator for grid-friendly behaviour. Results show that in summer, unmanaged PV feed-in from heterogeneous households causes substantial grid stress and balancing effort for the distribution system operator. Dynamic electricity prices can incentivise grid-friendly dispatch, but their effectiveness depends on the correlation between price signals and renewable availability and cannot guarantee grid-supportive behaviour alone. The grid agent reliably improves the grid-supportive coefficient, yet its operating strategy, for instance additional peak-reduction objectives, can interfere with price-based incentives. Effective demand-side management therefore requires careful analysis of stakeholder interactions. Building on this insight, thepaper provides a basic framework for the design, implementation, and assessment of both integrated and individual energy management strategies within a microgrid environment. By simulating the dynamic interactions among system participants and strategies, it enables comprehensive evaluation of their collective impact on the grid, supporting the development of robust solutions for future electricity networks.}}, author = {{Henne, Kevin and Rahlf, Henning Christoph and Naumann, Marius and Meschede, Henning}}, issn = {{2590-1745}}, journal = {{Energy Conversion and Management: X}}, keywords = {{Microgrid, Decentralised Energy Systems, Multi-Agent System, Residential Demand-Side Management, Optimisation}}, location = {{Dubrovnik}}, pages = {{102030}}, publisher = {{Elsevier}}, title = {{{Towards Stakeholder-Aware Demand-Side management assessment in heterogeneous residential Microgrids: A Multi-Agent approach}}}, doi = {{https://doi.org/10.1016/j.ecmx.2026.102030}}, volume = {{31}}, year = {{2026}}, } @inproceedings{66007, abstract = {{The reduction of CO2-emissions in the chemical industry is essential to meet European climate targets. Particularly, the reliance on fossil fuels for process heat supply is a key factor for CO2-emissions. Electrically driven compression heat pumps are a promising option to reduce fossil fuel consumption by upgrading low-temperature waste heat to a higher temperature level, provided that low-carbon electricity is available. However, the integration of heat pumps into chemical utility systems remains a challenge due to economic constraints and the high complexity associated with site-wide heat integration and retrofit of existing structures. This work presents a mixed-integer linear programming (MILP) approach for the optimization of utility systems with integrated heat pumps. To address computational complexity, candidate utility temperature levels are pre-selected, and feasible heat pump coefficients of performance (COP) are precomputed. The framework is applied to both greenfield and retrofit scenarios for a synthetic case study consisting of 400 process streams. In the greenfield scenario, optimal utility temperature levels and heat pump integration configurations are identified. For the retrofit scenario, temperature levels of an existing utility system are modified to reduce total annual costs (TAC). Additionally, sensitivity analysis is conducted to assess the influence of key economic and environmental parameters. The presented case studies demonstrate short solution times, highlighting the suitability of the proposed framework for screening studies and systematic sensitivity analyses in early-stage design and retrofit applications.}}, author = {{Hochhaus, Thorben and Grünewald, Marcus and Riese, Julia}}, booktitle = {{Systems and Control Transactions}}, issn = {{2818-4734}}, publisher = {{PSE Press}}, title = {{{Optimization of Site-wide Heat-Integrated Utility Systems with Heat Pumps using MILP}}}, doi = {{10.69997/sct.152209}}, volume = {{6}}, year = {{2026}}, }
