In Germany, where 80  % of household energy goes to space heating and hot water, shifting to low-carbon solutions is crucial. Fossil-fuelled district heating networks can incorporate renewable energy via heat pumps, improving efficiency. Although heat pump design typically favours minimal temperature lifts, higher lifts can be economically viable with low electricity prices and abundant renewables. Adding thermal energy storage boosts operational flexibility. This study explores a flexible heat pump operation incorporating part load behaviour with a thermal energy storage in a German city’s district heating system to minimise costs and carbon dioxide emissions. Using a mixed-integer linear programming model, it examines the impact of temperature adjustments and storage on system efficiency. The results show that the integration of a heat pump in a district heating system reduces operating costs. Compared to a supply without a heat pump, with levelised cost of heating of 9.98 cent/kWhth and a fixed operating mode with costs between 9.96 cent/kWhth and 11.49 cent/kWhth, the flexible use results in lowest costs of 9.85 cent/kWhth, while also reducing overall CO2 emissions. Using a full factorial sensitivity analysis, the levelised cost of heating ranged between 9.15 cent/kWhth in the best case and 10.37 cent/kWhth in the worst case for the selected configuration."}],"article_number":"121714","main_file_link":[{"open_access":"1","url":"https://www.sciencedirect.com/science/article/pii/S0196890426006837"}],"language":[{"iso":"eng"}],"doi":"10.1016/j.enconman.2026.121714","title":"Flexible operation strategies for heat pumps in district heating systems using dynamic electricity prices","year":"2026","author":[{"orcid":"0009-0006-8106-2132","last_name":"Rahlf","first_name":"Henning Christoph","full_name":"Rahlf, Henning Christoph","id":"56955"},{"last_name":"Divkovic","first_name":"Denis","full_name":"Divkovic, Denis","id":"89059"},{"first_name":"Lukas","orcid":"0009-0005-4727-7511","last_name":"Knorr","full_name":"Knorr, Lukas","id":"90391"},{"id":"88614","first_name":"Florian","last_name":"Schlosser","full_name":"Schlosser, Florian"},{"full_name":"Meschede, Henning","orcid":"0000-0002-1538-089X","first_name":"Henning","last_name":"Meschede","id":"86954"}],"publication_identifier":{"issn":["0196-8904"]},"publication_status":"published","date_updated":"2026-06-03T06:44:31Z","article_type":"original","intvolume":"       364"},{"article_type":"original","publication_status":"published","date_updated":"2026-06-03T06:42:54Z","publication_identifier":{"issn":["2666-9552"]},"author":[{"id":"56955","last_name":"Rahlf","orcid":"0009-0006-8106-2132","first_name":"Henning Christoph","full_name":"Rahlf, Henning Christoph"},{"full_name":"Knorr, Lukas","last_name":"Knorr","first_name":"Lukas","orcid":"0009-0005-4727-7511","id":"90391"},{"full_name":"Althoff, Simon","first_name":"Simon","last_name":"Althoff"},{"id":"86954","first_name":"Henning","last_name":"Meschede","orcid":"0000-0002-1538-089X","full_name":"Meschede, Henning"}],"year":"2026","title":"Analysis of bidirectional EV charging infrastructures within industrial DC grids","doi":"10.1016/j.segy.2026.100227","language":[{"iso":"eng"}],"article_number":"100227","main_file_link":[{"open_access":"1","url":"https://www.sciencedirect.com/science/article/pii/S266695522600002X"}],"abstract":[{"lang":"eng","text":"Industrial electrification is increasing to reduce fossil fuel dependence, alongside a growing share of volatile renewables.\r\nA secure and reliable energy supply is crucial for industry, leading to a shift from centralised to decentralised grid structures.\r\nDC microgrids becoming increasingly popular in industry, since they enable energy recuperation from braking, reduce components and cables, and integrate storage and local generation to manage supply interruptions or peak loads.\r\nEVs add further synergies by serving as mobile storage units, helping to store and redistribute locally generated renewable energy.\r\nThis paper analyses how EV integration in droop-controlled DC grids can contribute to a more stable, low-emission and peak-reduced load profile to the supply grid through load shifting and bridge interruptions.\r\nA droop-controlled DC grid model has been developed, incorporating an EV charging park based on probability functions.\r\nScalable scenarios allow for diverse condition analysis using an energy management system that utilises fuzzy logic and sequential MILP optimisation.\r\nIt has been shown that a 7% improvement of coefficient represented grid-serving behaviour is possible by load shifting.\r\nIt has also been demonstrated that an optimised EMS can reduce the demand-based CO2 emissions by 41kg for a representative day compared to a fuzzy logic EMS.\r\nAt the same time peak load is decreased yielding a more constant residual load.\r\nThese results highlight the potential of a controlled bidirectional charging infrastructure in DC grids and underscore the need to explicitly consider charging processes to ensure a residual load as constant as possible."}],"publication":"Smart Energy","department":[{"_id":"644"}],"type":"journal_article","keyword":["DC-grid","Droop control","Grid-serving behaviour","Grid stability","Bidirectional charging","Sequential decision","MILP optimisation"],"date_created":"2026-02-02T14:45:17Z","status":"public","user_id":"56955","_id":"63838","publisher":"Elsevier BV","quality_controlled":"1","citation":{"short":"H.C.

In order to effect a change in the mechanical properties of the semi-finished product, the material fed into the process can be modified. This enables the amalgamation of two alloys or the direct transition between them. The inhomogeneous flow conditions present within the tool give rise to the mixing of materials, thereby creating a graded multi-material zone. The multi-material zone was divided into different areas and traced back to the process conditions. Within the transitions, the connections between the alloys were examined, as well as the influence on the boundary layer.

The present study seeks to enhance the understanding of the relation between two forms of interactive gaze behavior – gaze aversions and mutual gaze – and the topical development in the explanatory discourse. To do so, we analyzed 24 dyadic board game explanations in which one explainer subsequently explained a board game to three different explainees while the board game was physically absent from the shared space. The main objective of the present study was to investigate the relation of gaze aversions and mutual gaze to the topical development of explanations. For this, based on previous research (Lazarov et al., 2024; Rossano, 2012) we hypothesized that (1) gaze aversions are more likely to be associated with topic changes than topic continuations, and that (2) mutual gaze is more likely to be associated with topic continuations than topic changes. In addition, we explored how the two forms of gaze behavior are related to the interlocutor who initiates a topic change or continuation. Our proportional analysis using a Generalized linear mixed effects model revealed that gaze aversions are related to topic changes initiated by both interlocutors. In contrast, the analysis did not reveal a significant relation between mutual gaze and topic continuations, which could be explained by the feedback elicitation function of mutual gaze at the end of speakers’ utterances (Bavelas et al., 2002; Brône et al., 2017; Kendon, 1967) while monitoring the addressees’ understanding (Clark &amp; Krych, 2004) and the complexity of the analyzed fixed and random effects.</jats:p>","lang":"eng"}],"date_created":"2026-05-05T14:19:47Z","department":[{"_id":"660"}],"type":"journal_article"},{"intvolume":"        59","publication_status":"published","date_updated":"2026-06-05T07:38:44Z","author":[{"first_name":"Christian","last_name":"Offen","full_name":"Offen, Christian"},{"id":"95394","full_name":"Wembe Moafo, Boris Edgar","first_name":"Boris Edgar","orcid":"0000-0002-6085-8071","last_name":"Wembe Moafo"},{"first_name":"Laura","last_name":"Ares","full_name":"Ares, Laura"},{"id":"75127","last_name":"Sperling","orcid":"0000-0002-5844-3205","first_name":"Jan","full_name":"Sperling, Jan"},{"id":"16494","first_name":"Sina","last_name":"Ober-Blöbaum","full_name":"Ober-Blöbaum, Sina"}],"publication_identifier":{"issn":["1751-8113","1751-8121"]},"title":"Numerical approaches to entangling dynamics from variational principles","year":"2026","doi":"10.1088/1751-8121/ae6d51","language":[{"iso":"eng"}],"article_number":"225303","abstract":[{"text":"<jats:title>Abstract</jats:title>\r\n                  <jats:p>In this work, we address the numerical identification of entanglement in dynamical scenarios. To this end, we consider different programs based on the restriction of the evolution to the set of separable (i.e., non-entangled) states, together with the discretization of the space of variables for numerical computations. As a first approach, we apply linear splitting methods to the restricted, continuous equations of motion derived from variational principles. We utilize an exchange interaction Hamiltonian to confirm that the numerical and analytical solutions coincide in the limit of small time steps. The application to different Hamiltonians shows the wide applicability of the method to detect dynamical entanglement. To avoid the derivation of analytical solutions for complex dynamics, we consider variational, numerical integration schemes, introducing a variational discretization for Lagrangians linear in velocities. Here, we examine and compare two approaches: one in which the system is discretized before the restriction is applied, and another in which the restriction precedes the discretization. We find that the ‘first-discretize-then-restrict’ method becomes numerically unstable, already for the example of an exchange-interaction Hamiltonian, which can be an important consideration for the numerical analysis of constrained quantum dynamics. Thereby, broadly applicable numerical tools, including their limitations, for studying entanglement over time are established for assessing the entangling power of processes that are used in quantum information theory.</jats:p>","lang":"eng"}],"issue":"22","publication":"Journal of Physics A: Mathematical and Theoretical","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"429"}],"type":"journal_article","date_created":"2026-06-05T07:37:43Z","status":"public","volume":59,"user_id":"75127","publisher":"IOP Publishing","_id":"65777","citation":{"mla":"Offen, Christian, et al. “Numerical Approaches to Entangling Dynamics from Variational Principles.” <i>Journal of Physics A: Mathematical and Theoretical</i>, vol. 59, no. 22, 225303, IOP Publishing, 2026, doi:<a href=\"https://doi.org/10.1088/1751-8121/ae6d51\">10.1088/1751-8121/ae6d51</a>.","bibtex":"@article{Offen_Wembe Moafo_Ares_Sperling_Ober-Blöbaum_2026, title={Numerical approaches to entangling dynamics from variational principles}, volume={59}, DOI={<a href=\"https://doi.org/10.1088/1751-8121/ae6d51\">10.1088/1751-8121/ae6d51</a>}, number={22225303}, journal={Journal of Physics A: Mathematical and Theoretical}, publisher={IOP Publishing}, author={Offen, Christian and Wembe Moafo, Boris Edgar and Ares, Laura and Sperling, Jan and Ober-Blöbaum, Sina}, year={2026} }","ama":"Offen C, Wembe Moafo BE, Ares L, Sperling J, Ober-Blöbaum S.

The study aims to delineate desirable and undesirable digital futures to inform policy discourse and strategic planning. It begins with the outlining of the research basis and methodology, where it employs a methodological synthesis of the Scenario Development Technique from the UN Strategic Foresight Guide and STEEP Analysis. This approach integrates a macro environmental assessment of socio-cultural, technological, economic, environmental, and political dimensions to identify key drivers of change and differences. These are then mapped onto a two-by-two matrix defined by two primary axes. This combination enabled the development of four scenarios examining the impact of digital technologies across these dimensions. The scenarios diverge along two axes. The vertical axis represents the mode of societal organisation and political power (authoritarianism versus democracy). The horizontal axis represents the mode of governance and citizen engagement (representation versus participation). By contrasting these divergent paths, this paper provides a critical framework for analysing how digital technologies intersect with political will and socioeconomic structures.","lang":"eng"}],"publication":"Open Research Europe","department":[{"_id":"136"},{"_id":"11"}],"type":"journal_article","date_created":"2026-06-04T20:14:20Z","has_accepted_license":"1","status":"public","volume":6,"user_id":"21863","publisher":"F1000 Research Ltd","_id":"65776","project":[{"name":"INNOVAtive DEmocracy Through Digitalisation","_id":"1397"}],"quality_controlled":"1","citation":{"ieee":"C.

In practical transducer applications, the relevant operating points are influenced by mechanical preload and heating, both of which give rise to changes in the elastic, dielectric, and piezoelectric material properties. Material parameters identified under idealised, unloaded conditions are therefore insufficient to represent piezoceramic material behaviour under realistic operating conditions. To overcome this limitation, experimental setups are developed that enable the measurement of electrical impedance spectra under controlled thermal and mechanical conditions. The acquired impedance data are used in an inverse identification procedure, in which the behaviour of a finite element forward model is iteratively fitted to the measurements using a block coordinate descent optimisation strategy guided by a sensitivity analysis. This yields effective linear material parameters as a function of temperature and mechanical stress at varying operating points. The identified temperature-dependent parameters, for instance, can be employed in a coupled thermo-electromechanical simulation framework to predict the temperature-dependent material behaviour during operation. The linear identification based on varying operation points provides an initial approximation of the nonlinear material response, establishing a basis for the development of corresponding nonlinear material models.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"doi":"10.1515/teme-2026-0042","publication_identifier":{"issn":["0171-8096","2196-7113"]},"author":[{"id":"44026","first_name":"Olga","orcid":"0009-0007-5598-9484","last_name":"Friesen","full_name":"Friesen, Olga"},{"orcid":"0000-0002-4393-268X","first_name":"Leander","last_name":"Claes","full_name":"Claes, Leander","id":"11829"},{"last_name":"Hölscher","first_name":"Jonas","full_name":"Hölscher, Jonas","id":"73952"},{"id":"213","full_name":"Henning, Bernd","first_name":"Bernd","last_name":"Henning"},{"first_name":"Claus","last_name":"Scheidemann","full_name":"Scheidemann, Claus","id":"38259"},{"id":"210","first_name":"Tobias","last_name":"Hemsel","full_name":"Hemsel, Tobias"},{"first_name":"Raphael","last_name":"Kuess","full_name":"Kuess, Raphael"},{"last_name":"Walther","first_name":"Andrea","full_name":"Walther, Andrea"},{"id":"67587","first_name":"Carsten","last_name":"Spieker","full_name":"Spieker, Carsten"},{"id":"158","full_name":"Förstner, Jens","first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner"}],"year":"2026","title":"Measurement of multiphysical material parameters of piezoceramic components for high-power ultrasonic applications","publication_status":"published","date_updated":"2026-06-08T17:54:45Z"},{"quality_controlled":"1","citation":{"mla":"Houari, Fadoua, et al. “A Verification-Stability-Validation Framework for Optimal Hyperelastic Modeling of Rubber-like Materials.” <i>Mechanics of Materials</i>, vol. 220, 105740, Elsevier BV, 2026, doi:<a href=\"https://doi.org/10.1016/j.mechmat.2026.105740\">10.1016/j.mechmat.2026.105740</a>.","ama":"Houari F, Caylak I, Ostwald R.
