We consider semidefinite programs (SDPs) that approximate the maximum acceptance probability of a measurement over separable states, the optimization problem underlying QMA(2). In the extended-formulation model of Harrow, Natarajan, and Wu (HNW), all measurements share a common feasible region and an objective-independent embedding of product states that exactly reproduces their acceptance probabilities. For every $0<θ<2/7$, there are constants $c_θ,a_θ>0$ such that, for sufficiently large $d$, any such SDP with uniform additive error $0<a\\le a_θ$ has size at least $d^{c_θ\\min\\{a^{-1/3},d^θ\\}}$. The bound applies at sufficiently small constant error, is superpolynomial in $d$ whenever $a=o(1)$, and becomes $d^{Ω(d^θ)}$ when $a\\le d^{-3θ}$, improving HNW's quasipolynomial bound at inverse- square error. The same bound holds for any SDP-representable convex set of states that contains all separable states and lies within trace distance $a$ of them, giving a quantitative counterpart to Fawzi's theorem that the separable set has no exact semidefinite representation. Our proof combines the quantitative pseudo-density theorem of Lee, Raghavendra, and Steurer with explicit block-positive operators and Chebyshev amplification. Our main results are supported by Lean proofs.","lang":"eng"}],"language":[{"iso":"eng"}],"_id":"67088","user_id":"71541","title":"Semidefinite extension complexity of the separable set, with applications to approximate disentanglers","status":"public","year":"2026","author":[{"last_name":"Gharibian","first_name":"Sevag","orcid":"0000-0002-9992-3379","full_name":"Gharibian, Sevag","id":"71541"},{"first_name":"Carsten","last_name":"Hecht","full_name":"Hecht, Carsten"},{"id":"57863","full_name":"Rudolph, Dorian","first_name":"Dorian","last_name":"Rudolph"}],"date_updated":"2026-09-09T12:07:31Z","publication_status":"unpublished"},{"type":"preprint","department":[{"_id":"548"},{"_id":"10"},{"_id":"34"}],"date_created":"2026-09-14T07:49:06Z","abstract":[{"text":"A weighted dynamical version $\\mathbf{Z}_f$ of the classical Ihara zeta function is presented on connected finite regular graphs, expressed in terms of weighted periodic orbit data.

Finding the right settings for parameters through automated algorithm configuration has become a critical component of designing competitive algorithms. While traditional offline configurators tackle this problem by finding one configuration that works well for a set of instances, instance-specific algorithm configuration utilizes features of the instances to provide configurations that are tailored to each instance to maximize performance. We propose the first instance-specific algorithm configurator based on deep reinforcement learning that can be used in general algorithm configuration settings. Our method is able to handle large, mixed, discrete and continuous search spaces and only requires a small number of instances for training. Not only does it select an individual configuration for every instance, it also selects configurations from a much broader range. We show that our configurator provides improvements over the state-of-the-art instance-specific configurators ISAC++ and Hydra on a wide range of problem domains.</jats:p>"}],"citation":{"ieee":"E.

This has given rise to the concept of Social XAI. However, ontological modelling of the Social XAI framework remains limited. In particular, there is a lack of models that capture the progressivity of explanation processes in terms of the changes that occur. This paper introduces the Social XAI Ontology, a BFO-based reference ontology. The ontology models a variety of entities involved in the process of explanation. First, it provides a model of the participants in explanatory dialogues, such as artificial explainers and human explainees, and the roles they may take. Then, it introduces a rich set of explanatory moves that explainers and explainees perform. The paper further presents ontological accounts of four types of context that are central to real-world Social XAI projects. Furthermore, it provides an ontological account of different dimensions of adaptivity, which is considered to be an essential prerequisite for realizing Social XAI systems. Finally, the paper revisits two existing models of understanding in Social XAI by applying a recent theory of change. The paper concludes by discussing use cases for the Social XAI Ontology."}],"_id":"67190","publisher":"IOS Press","page":"181–198","ddc":["000"],"user_id":"76456","conference":{"end_date":"2026-09-25","location":"Vitória, ES, Brazil","start_date":"2026-09-21","name":"16th International Conference on Formal Ontology in Information Systems (FOIS 2026)"},"status":"public","has_accepted_license":"1","place":"Amsterdam, The Netherlands","citation":{"short":"M.

Conventional heating, ventilation, and air conditioning (HVAC) systems rely on numerous air outlet temperature sensors, which add significant costs at scale. This study introduces a hybrid virtual sensor concept that combines physics-based mathematical modeling with data-driven methods to address this challenge. A detailed physical model predicts air outlet temperatures, while neural networks capture unmodeled heat exchanges and environmental disturbances. Two hybrid strategies are explored: one augments the physical model with a neural network to learn residual heat flows, and the other employs an adiabatic physical model enhanced by a neural network that maps the total environmental heat exchange, supported by a disturbance observer for accurate heat flow estimation. Evaluation using measurement data from a real test vehicle in a simplified two-vent scenario demonstrates that hybrid virtual sensors can provide reliable temperature estimates, reduce reliance on hardware sensors, and maintain high control performance, highlighting the potential of integrating physics-based and machine learning methods in vehicle climate control systems.","lang":"eng"}],"publication":"2026 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM)","user_id":"15402","publisher":"IEEE","_id":"67194","status":"public","conference":{"location":"Genova, Italy","start_date":"07.07.2026","name":"Conference on Advanced Intelligent Mechatronics (AIM)","end_date":"11.07.2026"},"oa":"1","quality_controlled":"1","citation":{"ieee":"J.

Using service-dominant logic (SDL) as a theoretical lens, we review the distinctive properties of these concepts, introduce the agent concept into SDL, and analyze GenAI’s precise role in service exchange processes. We employ a two-phase research approach: First, we conduct a systematic literature review to derive defining properties of resources, actors, beneficiaries, and agents. We then assess eight contemporary GenAI systems against these properties. Our evidence indicates that GenAI is best understood as an operant resource and, depending on design and context, as an actor and agent. Conversely, GenAI does not qualify as a beneficiary, as it is neither individually capable of phenomenologically experiencing and determining value nor a social system of individuals with such capacities. Our findings propose an update to SDL’s core concepts and understanding, as well as a nuanced conceptual clarification of GenAI’s role, offering guidance for researchers and practitioners seeking to understand and design service interactions that incorporate GenAI."}],"date_created":"2026-09-18T09:52:01Z","keyword":["Generative artificial intelligence","Service-dominant logic","Service science","Actor","Beneficiary","Agent"],"type":"journal_article","department":[{"_id":"195"}],"year":"2026","title":"Resource, actor, beneficiary, or agent?

Ein möglicher Ansatz, um Bauteilfälschungen z.B. in der Luft- und Raumfahrtindustrie sowie im Automotive-Bereich künftig zu verhindern, besteht darin, einen unverwechselbaren, unumkehrbaren „Identifier“ in das Originalbauteil zu integrieren. Dies könnte beispielsweise ein unsichtbarer magnetischer Bar- oder QR-Code sein, der während der Fertigung direkt in das Bauteil integriert wird. Die gezielte Beeinflussung der magnetischen Eigenschaften während des Fertigungsprozesses von Bauteilen durch die Umformtechnik stellt nach aktuellem Stand der Technik eine anspruchsvolle Herausforderung dar. Ein vielversprechender Forschungsansatz zur Lösung dieses Problems ist das Konzept der sogenannten Eigenschaftsregelung. Bei diesem Konzept werden die Bauteileigenschaften mittels intelligenter Sensoren direkt während der Fertigung gemessen und durch die Maschinenaktorik in den Prozess zurückgekoppelt. Dies ermöglicht eine dynamische Anpassung der Fertigungsparameter, um die gewünschten Eigenschaften des Bauteils zu erreichen. Dieser Beitrag beleuchtet am Beispiel des Drückwalzprozesses für metastabil-austenitischer Edelstähle, wie mit einer solchen Eigenschaftsregelung definierte und gradierte Eigenschaftsstrukturen z.B. zur Verhinderung von Produktfälschungen hergestellt werden können. Eine Hauptherausforderung bei der Entwicklung der Eigenschaftsregelung für das Drückwalzen metastabil-austenitischer Edelstähle ist insbesondere die Online-Messbarkeit des Gefüges in-situ im Prozess. Hierzu ist innerhalb der Eigenschaftsregelung eine indirekte, zerstörungsfreie Messung mittels einer neuartigen, intelligenten Softsensorik unabdingbar. Diese Sensorik besitzt eine charakteristische Dynamik und Ortsauflösung, welche mittelbar die Auflösung der geregelt erzeugten Gradierungen beeinflusst, d.h. die Schärfe der Abgrenzung zwischen martensitischen und nicht-martensitischen Bereichen. Dieser Aspekt wird Rahmen des vorliegenden Beitrags im Rahmen einer Simulationsstudie näher beleuchtet und ein Quervergleich zwischen Sensordynamik, Regelungsbandbreite und resultierenden und der erreichbaren Gradierungsauflösung gezogen. Insbesondere der letzte Aspekt ist von hoher Relevanz für einen etwaigen zukünftigen Technologietransfer der smarten, funktionsintegrierten Strukturen von der Forschung in die industrielle Anwendung.","lang":"ger"}],"related_material":{"link":[{"relation":"confirmation","url":"https://publica.fraunhofer.de/entities/publication/7b7d4dc8-4dd6-4cfb-a5c4-c8d60100e9fb"}]},"date_created":"2026-09-22T08:03:45Z","department":[{"_id":"153"},{"_id":"156"},{"_id":"241"}],"type":"conference"},{"main_file_link":[{"open_access":"1","url":"https://www.scientific.net/SSP.389.253.pdf"}],"language":[{"iso":"eng"}],"doi":"10.4028/p-gad5rr","year":"2026","title":"Reducing the Uncertainty in Flow Forming of Metastable Austenites","publication_identifier":{"issn":["1662-9779"]},"author":[{"full_name":"Kersting, Lukas","first_name":"Lukas","last_name":"Kersting"},{"full_name":"Koyuncu, Mustafa","last_name":"Koyuncu","first_name":"Mustafa"},{"full_name":"Arian, Bahman","last_name":"Arian","first_name":"Bahman","id":"36287"},{"full_name":"Rozo Vasquez, Julian","first_name":"Julian","last_name":"Rozo Vasquez"},{"id":"552","last_name":"Trächtler","first_name":"Ansgar","full_name":"Trächtler, Ansgar"},{"last_name":"Homberg","first_name":"Werner","full_name":"Homberg, Werner","id":"233"},{"full_name":"Walther, Frank","first_name":"Frank","last_name":"Walther"}],"date_updated":"2026-09-22T10:02:23Z","publication_status":"published","intvolume":"       389","article_type":"original","date_created":"2026-09-18T08:32:16Z","type":"journal_article","department":[{"_id":"153"},{"_id":"156"},{"_id":"241"}],"publication":"Solid State Phenomena","abstract":[{"text":"<jats:p>Flow forming of metastable austenites is an innovative, incremental metal forming process with special capabilities due to the TRIP effect. However, the TRIP effect during flow forming is significantly affected by disturbances and especially batch fluctuations leading to process uncertainty. This aspect is further analyzed and quantified in this paper to give insights on how to minimize the impact of uncertainty. For this purpose, semifinished parts and resulting flow forming workpieces are systemically characterized concerning their properties and the property uncertainty supported by mathematical methods like correlation analysis and error propagation. A result is that the most influencing impact factor on the strain induced α’-martensite volume fraction as a material property are batch fluctuations, specifically the variations of the chemical composition. Those especially appear from batch to batch, but also within a batch accompanied by e.g. temperature effects. To counter this challenge, different methods from control theory like closed-loop property control and adaptive control can be applied to flow forming. Thus, uncertainty will be reduced to increase process robustness and to enable industrial exploitation of the TRIP effect in flow forming of metastable austenitic steels.</jats:p>","lang":"eng"}],"page":"253-266","publisher":"Trans Tech Publications, Ltd.","_id":"67171","user_id":"82875","volume":389,"status":"public","oa":"1","citation":{"bibtex":"@article{Kersting_Koyuncu_Arian_Rozo Vasquez_Trächtler_Homberg_Walther_2026, title={Reducing the Uncertainty in Flow Forming of Metastable Austenites}, volume={389}, DOI={<a href=\"https://doi.org/10.4028/p-gad5rr\">10.4028/p-gad5rr</a>}, journal={Solid State Phenomena}, publisher={Trans Tech Publications, Ltd.}, author={Kersting, Lukas and Koyuncu, Mustafa and Arian, Bahman and Rozo Vasquez, Julian and Trächtler, Ansgar and Homberg, Werner and Walther, Frank}, year={2026}, pages={253–266} }","ama":"Kersting L, Koyuncu M, Arian B, et al.
