To this end, experiments are performed, which show the following characteristics: localization phenomena in the form of a shear band, softening behavior in the force‐displacement curve, and asymmetric behavior for compression and tension. To model this complex material behavior, a micromorphic continuum is used. In the present contribution, we focus on the linear‐elastic regime and demonstrate the identifiability of micromorphic material parameters under deliberately induced inhomogeneous deformation states. In addition to the degrees of freedom of a classical continuum, the micromorphic model has additional degrees of freedom, introduced here in a phenomenological sense to represent kinematically enriched deformation modes associated with the granular microstructure. Accordingly, the micromorphic fields are not interpreted as a separate physical scale (e.g., “binder” vs. “grains”), but as an effective continuum description at the specimen scale. This contribution addresses parameter identification for a micromorphic model of cold‐box sand, with a clear separation between homogeneous deformation states governing classical elastic parameters and inhomogeneous states required to activate and identify micromorphic length‐scale parameters. The main challenge lies in identifying the micro material parameters. To determine these, the corresponding gradient terms in the constitutive formulation must be triggered via properly tuned experiments. Micro‐parameter identification is demonstrated using synthetic data generated from a boundary‐value problem with inhomogeneous displacement fields. The chosen benchmark enables controlled activation of gradient terms and thereby renders optimization‐based identification of micromorphic parameters feasible. The synthetic example is deliberately chosen to assess feasibility and identifiability under controlled conditions, thereby isolating micromorphic identifiability aspects from experimental uncertainties. The novelty of the contribution lies in explicitly linking micromorphic parameter identifiability to kinematic inhomogeneity, and in demonstrating this link within a tractable forward– inverse setting for a linear‐elastic micromorphic continuum.</jats:p>"}],"publisher":"Wiley","date_created":"2026-04-01T04:52:34Z","title":"Aspects of Parameter Identification for a Micromorphic Continuum applied to a Cold‐Box Sand","quality_controlled":"1","issue":"2","year":"2026","_id":"65266","user_id":"85414","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"article_number":"e70093","type":"journal_article","status":"public","date_updated":"2026-04-01T04:54:17Z","author":[{"last_name":"Börger","full_name":"Börger, Alexander","id":"52037","first_name":"Alexander"},{"full_name":"Mahnken, Rolf","last_name":"Mahnken","first_name":"Rolf"},{"last_name":"Caylak","id":"75","full_name":"Caylak, Ismail","first_name":"Ismail"},{"id":"106876","full_name":"Ostwald, Richard","last_name":"Ostwald","orcid":"0000-0003-2147-8444","first_name":"Richard"}],"volume":26,"doi":"10.1002/pamm.70093","publication_status":"published","publication_identifier":{"issn":["1617-7061","1617-7061"]},"citation":{"mla":"Börger, Alexander, et al. “Aspects of Parameter Identification for a Micromorphic Continuum Applied to a Cold‐Box Sand.” <i>Proceedings in Applied Mathematics and Mechanics</i>, vol. 26, no. 2, e70093, Wiley, 2026, doi:<a href=\"https://doi.org/10.1002/pamm.70093\">10.1002/pamm.70093</a>.","short":"A.

Systems theory offers powerful concepts to address challenges of growing system complexity and non-systemic design approaches in information systems. Despite its systemic origins, systems theory remains a peripheral topic in IS. The study addresses this gap by introducing a comprehensive framework of 52 systems-theoretical concepts to guide the design of complex IS artifacts. We synthesize scattered systems knowledge from diverse disciplines to provide a unified level of abstraction for complex information system design. We apply the framework to a use case of business reputation systems to show how the systems lens informs the design of a novel, complex information system. We make three key contributions to the literature. First, the framework provides a common ground for interdisciplinary research in information system design. Second, it offers a unified level of abstraction grounded in systems theory that serves as a coherent basis for artifact design. Third, it demonstrates the potential of systems theory as a foundational justificatory knowledge base. Furthermore, we provide guidance on applying the framework across multiple modes of reasoning, alongside further application guidelines. The study thus serves as a bridge between the body of systems knowledge and contextual design in IS.","lang":"eng"}],"external_id":{"unknown":["https://aisel.aisnet.org/cais/vol58/iss1/37/"]},"keyword":["Information Systems Research","Systems Theory","System Complexity","System Design","Design Science"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2026","publisher":"AIS","date_created":"2026-04-02T04:19:09Z","title":"Bridging Systems Theory and Information Systems: A Framework for Designing Complex Information Systems","type":"journal_article","status":"public","_id":"65311","department":[{"_id":"195"}],"user_id":"83557","article_type":"review","extern":"1","alternative_title":["Design Your System"],"publication_identifier":{"unknown":["1529-3181"]},"publication_status":"published","jel":["D83","L14","D83","O33","C63","P"],"citation":{"short":"U.

Cli-ents who have not worked with a particular consultancy face considerable risk when they place an order while lacking reliable information about the service quality they can expect. There is a strong link between trust and reputation, as the positive reputation of a consultancy can act as a substitute for a new client’s missing individual experience with the provider, fostering trust in the service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo facilitate trustworthy signals, we design and implement a novel reputation mechanism that carries a monetary weight stored on a blockchain network as an immutable, decentralized, and transparent ledger. Based on an implementation in the Ethereum network and subsequent evaluation, we conclude that the reputation mechanism can contribute to leveling information asymmetry and reducing risk while increasing reputation and trust. The mechanism lends itself to being used in other business-to-business scenarios that suffer from similar information asymmetries."}],"status":"public","publication":" Advanced Studies in Consulting Research and Digitalization – A Scientific Update on the Digital Transformation of the Consulting Industry.

Our work studies the representation of them in language models using three fine-tuning strategies. The models are trained on three dialogue corpora in English and Japanese, where backchannels and fillers are preserved and annotated, to investigate how fine-tuning can help LMs learn their representations. We first apply clustering analysis to the learnt representation of backchannels and fillers, and have found increased silhouette scores in representations from fine-tuned models, which suggests that fine-tuning enables LMs to distinguish the nuanced semantic variation in different backchannel and filler use. We also use natural language generation (NLG) metrics and qualitative analysis to confirm that the utterances generated by fine-tuned language models resemble human-produced utterances more closely. Our findings suggest the potentials of transforming general LMs into conversational LMs that are more capable of producing human-like languages adequately."}],"status":"public","type":"conference","language":[{"iso":"eng"}],"project":[{"_id":"112","name":"TRR 318; TP A02: Verstehensprozess einer Erklärung beobachten und auswerten"}],"_id":"61444","user_id":"76456","department":[{"_id":"660"}],"year":"2026","citation":{"apa":"Wang, Y., Lao, L., Huang, L., Skantze, G., Xu, Y., &#38; Buschmeier, H.

We address this question by introducing a new method called AutoPeriod of Surprisal (APS). APS adopts a canonical periodicity detection algorithm and is able to identify any significant periods that exist in the surprisal sequence of a single document. By applying the algorithm to a set of corpora, we have obtained the following interesting results: Firstly, a considerable proportion of human language demonstrates a strong pattern of periodicity in information; Secondly, new periods that are outside the distributions of typical structural units in text (e.g., sentence boundaries, elementary discourse units, etc.) are found and further confirmed via harmonic regression modeling. We conclude that the periodicity of information in language is a joint outcome from both structured factors and other driving factors that take effect at longer distances. The advantages of our periodicity detection method and its potentials in LLM-generation detection are further discussed.","lang":"eng"}],"status":"public","date_updated":"2026-04-07T09:56:53Z","author":[{"first_name":"Yulin","full_name":"Ou, Yulin","last_name":"Ou"},{"last_name":"Wang","full_name":"Wang, Yu","first_name":"Yu"},{"first_name":"Yang","last_name":"Xu","full_name":"Xu, Yang"},{"first_name":"Hendrik","last_name":"Buschmeier","orcid":"0000-0002-9613-5713","id":"76456","full_name":"Buschmeier, Hendrik"}],"date_created":"2026-04-07T09:52:23Z","title":"Identifying the periodicity of information in natural language","conference":{"end_date":"2026-07-07","location":"San Diego, CA, USA","name":"64th Annual Meeting of the Association for Computational Linguistics","start_date":"2026-07-02"},"quality_controlled":"1","publication_status":"accepted","year":"2026","citation":{"apa":"Ou, Y., Wang, Y., Xu, Y., &#38; Buschmeier, H.

Understanding the properties of these layers in relation to device performance is essential for optimizing solar cell efficiency and enabling their integration into emerging architectures, such as flexible solar cells. Here, we deposited TiO2 at different thicknesses using atomic layer deposition (ALD), a technique well-suited for producing uniform and pinhole-free films. The crystal structure of the layers was controlled by depositing the films at three different temperatures: 150 °C, 250 °C, and 350 °C. The layers were characterized in detail to determine the morphology (by atomic force microscopy), surface composition (by X-ray photoelectron spectroscopy) and the crystal structure (by X-ray diffraction). The TiO2 layers were then incorporated as ETLs in planar perovskite solar cells to evaluate their influence on device performance. Higher deposition temperatures led to improvements in device fill factor and open-circuit voltage, leading to more efficient solar cells. Notably, the best device performance for the ALD-TiO2 layers was achieved with films deposited at 250 °C.","lang":"eng"}],"publication":"Applied Surface Science","type":"journal_article"}]
