An important class of metasurface functionalities is associated with asymmetry in both the generation and transmission of light with respect to reversals of the positions of emitters and receivers. The nonlinear light–matter interaction in metasurfaces offers a promising pathway towards miniaturization of the asymmetric control of light. Here we demonstrate asymmetric parametric generation of light in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators into translucent metasurfaces that produce images in the visible spectral range on being illuminated by infrared radiation. By design, the metasurfaces produce different and completely independent images for the reversed direction of illumination, that is, when the positions of the infrared emitter and the visible light receiver are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength resonators paves the way towards novel nanophotonic components via dense integration of large quantities of nonlinear resonators into compact metasurface designs."}],"page":"561–565","publisher":"Springer Science and Business Media LLC","_id":"32088","user_id":"30525","volume":16,"status":"public","oa":"1","citation":{"bibtex":"@article{Kruk_Wang_Sain_Dong_Yang_Zentgraf_Kivshar_2022, title={Asymmetric parametric generation of images with nonlinear dielectric metasurfaces}, volume={16}, DOI={<a href=\"https://doi.org/10.1038/s41566-022-01018-7\">10.1038/s41566-022-01018-7</a>}, journal={Nature Photonics}, publisher={Springer Science and Business Media LLC}, author={Kruk, Sergey S. and Wang, Lei and Sain, Basudeb and Dong, Zhaogang and Yang, Joel and Zentgraf, Thomas and Kivshar, Yuri}, year={2022}, pages={561–565} }","ama":"Kruk SS, Wang L, Sain B, et al.

The reflector stacks are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and 800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis. The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by the photonic structure. When the optical bandgap of the reflector is in resonance with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related emission mode is suppressed. Strong NBE emission is observed even when the ZnO layer does not show any NBE emission (due to low crystallinity) in the absence of the photonic structure. With this cost-efficient synthesis method, emitters for, e.g., luminescent gas sensors can be fabricated.","lang":"eng"}],"publication":"Advanced Materials Interfaces","department":[{"_id":"15"},{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"230"}],"type":"journal_article","keyword":["Mechanical Engineering","Mechanics of Materials"],"date_created":"2022-02-08T15:24:58Z","intvolume":"         9","article_type":"original","date_updated":"2025-05-27T07:42:58Z","publication_status":"published","publication_identifier":{"issn":["2196-7350","2196-7350"]},"author":[{"full_name":"Kothe, Linda","first_name":"Linda","last_name":"Kothe"},{"full_name":"Albert, Maximilian","last_name":"Albert","first_name":"Maximilian"},{"full_name":"Meier, Cedrik","first_name":"Cedrik","last_name":"Meier","orcid":"https://orcid.org/0000-0002-3787-3572","id":"20798"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"},{"last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael","id":"23547"}],"title":"Stimulation and Enhancement of Near‐Band‐Edge Emission in Zinc Oxide by Distributed Bragg Reflectors","year":"2022","doi":"10.1002/admi.202102357","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202102357","open_access":"1"}],"article_number":"2102357","quality_controlled":"1","citation":{"ieee":"L.

In this review article, we give an overview of past and current research on how intelligent agents should be able to both give meaningful feedback toward humans, as well as understanding feedback given by the users. The review covers feedback across different modalities (e.g., speech, head gestures, gaze, and facial expression), different forms of feedback (e.g., backchannels, clarification requests), and models for allowing the agent to assess the user's level of understanding and adapt its behavior accordingly. Finally, we analyse some shortcomings of current approaches to modeling feedback, and identify important directions for future research."}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"doi":"10.3389/fcomp.2022.744574","publication_identifier":{"issn":["2624-9898"]},"author":[{"full_name":"Axelsson, Agnes","first_name":"Agnes","last_name":"Axelsson"},{"first_name":"Hendrik","orcid":"0000-0002-9613-5713","last_name":"Buschmeier","full_name":"Buschmeier, Hendrik","id":"76456"},{"first_name":"Gabriel","last_name":"Skantze","full_name":"Skantze, Gabriel"}],"year":"2022","title":"Modeling Feedback in Interaction With Conversational Agents—A Review","intvolume":"         4","publication_status":"published","date_updated":"2025-09-11T10:17:11Z","oa":"1","citation":{"ama":"Axelsson A, Buschmeier H, Skantze G.

We find three principal configurations of hole polarons: (i) self-trapped holes localized at displaced regular oxygen atoms and (ii) two other configurations bound to a lithium vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated oxygen atom below the defect. The latter is the most stable and is in excellent quantitative agreement with measured g factors from electron paramagnetic resonance. Due to the absence of mid-gap states, none of these hole polarons can explain the broad optical absorption centered between 2.5 and 2.8 eV that is observed in transient absorption spectroscopy, but such states appear if a free electron polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon experiments. The coexistence of hole and exciton polarons, which are simultaneously created in optical excitations, thus satisfactorily explains the reported experimental data."}],"issue":"11","publication":"Crystals","doi":"10.3390/cryst12111586","language":[{"iso":"eng"}],"article_number":"1586","article_type":"original","intvolume":"        12","publication_status":"published","date_updated":"2025-09-18T13:28:05Z","author":[{"full_name":"Schmidt, Falko","orcid":"0000-0002-5071-5528","last_name":"Schmidt","first_name":"Falko","id":"35251"},{"full_name":"Kozub, Agnieszka L.","first_name":"Agnieszka L.","orcid":"0000-0001-6584-0201","last_name":"Kozub","id":"77566"},{"first_name":"Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann","full_name":"Gerstmann, Uwe","id":"171"},{"full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","last_name":"Schmidt","id":"468"},{"id":"458","full_name":"Schindlmayr, Arno","first_name":"Arno","orcid":"0000-0002-4855-071X","last_name":"Schindlmayr"}],"publication_identifier":{"eissn":["2073-4352"]},"year":"2022","title":"A density-functional theory study of hole and defect-bound exciton polarons in lithium niobate"},{"oa":"1","citation":{"apa":"Abdelrahem, M.

Mit seinen uṣūl-Werken konstruierte der šāfiʿitische Muʿtazilit ʿAbd al-Ǧabbār, Systematiker der muʿtazilitischen Dogmenlehre, eine rechtsphilosophische, rational geprägte Theorie und gilt damit als eine der bedeutendsten ›Stationen‹ auf dem Weg der Methodologie der Theolog:innen sowie des Verhältnisses zwischen der kalām-Lehre und den uṣūl al-fiqh. Bei seiner Beschäftigung mit den verschiedenen Rechtsquellen des islamischen Rechts führt er drei Voraussetzungen für ihre gesetzgebende Funktion an.

We reveal nanoscale spinodal decomposition in pristine Co2FeO4. The interfaces of Co-rich and Fe-rich nanodomains of Co2FeO4 become trapping sites for hydroxyl groups, contributing to a higher OER activity compared to that of CoFe2O4. However, the activity of Co2FeO4 drops considerably due to concurrent irreversible transformation towards CoIVO2 and pronounced Fe dissolution. In contrast, there is negligible elemental redistribution for CoFe2O4 after OER, except for surface structural transformation towards (FeIII, CoIII)2O3.

Although these structural features are crucial for their performance, the mechanisms behind such transitions are not well understood. Herein, we describe the mechanism of transformation from layered 2D δ-MnO2 nanosheets to the scarcely reported γ-MnO2 nanocone morphology. Despite the common purpose of introducing Fe dopants to enhance the conductivity of layered manganese oxides, the Fe galvanic exchange reaction was found responsible for such coupled phase/morphology transition. Electrochemical characterization confirmed a distinct electrochemical behaviour of the nanocones, emphasizing the need to unravel the mechanism of 2D MnO2 transformation. Such mechanistic insights were gained by systematic and rigorous electron microscopy studies. The effect of the local chemical composition was determined by energy dispersive X-ray spectroscopy while electron energy loss spectroscopy unravelled the key influence of the oxidation state of Mn ions within nanosheets and nanocones. We propose and demonstrate a Mn2+-mediated oxidative mechanism of coupled morphology/phase transformation subjected to the equilibrium of Fe and Mn ions during galvanic exchange reaction. These findings contribute to the understanding of the growth and morphology/phase transformations of manganese oxide nanostructures, providing insights for the rational design of nanomaterials.","lang":"eng"}],"date_created":"2025-12-03T16:02:15Z","department":[{"_id":"985"}],"keyword":["manganese oxide","nanomaterials","TEM","supercapacitors"],"type":"journal_article","status":"public","_id":"62813","publisher":"Royal Society of Chemistry (RSC)","page":"24190-24198","volume":10,"user_id":"116779","citation":{"ama":"Aymerich-Armengol R, Cignoni P, Ebbinghaus P, et al.

This work presents <jats:sc>VarAlyzer</jats:sc>, a novel static analysis approach for software product lines. <jats:sc>VarAlyzer</jats:sc> first transforms preprocessor constructs to plain C while preserving their variability and semantics. It then solves any given distributive analysis problem on transformed product lines in a variability-aware manner. <jats:sc>VarAlyzer</jats:sc> ’s analysis results are annotated with feature constraints that encode in which configurations each result holds. Our experiments with 95 compilation units of OpenSSL show that applying <jats:sc>VarAlyzer</jats:sc> enables one to conduct inter-procedural, flow-, field- and context-sensitive data-flow analyses on entire product lines for the first time, outperforming the product-based approach for highly-configurable systems.</jats:p>","lang":"eng"}],"date_created":"2022-03-25T07:41:26Z","department":[{"_id":"76"}],"type":"journal_article","keyword":["inter-procedural static analysis","software product lines","preprocessor","LLVM","C/C++"],"publication_identifier":{"issn":["0928-8910","1573-7535"]},"author":[{"first_name":"Philipp","last_name":"Schubert","orcid":"0000-0002-8674-1859","full_name":"Schubert, Philipp","id":"60543"},{"full_name":"Gazzillo, Paul","last_name":"Gazzillo","first_name":"Paul"},{"full_name":"Patterson, Zach","first_name":"Zach","last_name":"Patterson"},{"first_name":"Julian","last_name":"Braha","full_name":"Braha, Julian"},{"orcid":"0009-0008-6867-9802","first_name":"Fabian Benedikt","last_name":"Schiebel","full_name":"Schiebel, Fabian Benedikt","id":"55745"},{"full_name":"Hermann, Ben","first_name":"Ben","orcid":"0000-0001-9848-2017","last_name":"Hermann","id":"66173"},{"full_name":"Wei, Shiyi","first_name":"Shiyi","last_name":"Wei"},{"full_name":"Bodden, Eric","first_name":"Eric","orcid":"0000-0003-3470-3647","last_name":"Bodden","id":"59256"}],"title":"Static data-flow analysis for software product lines in C","year":"2022","intvolume":"        29","article_type":"original","date_updated":"2025-12-04T10:42:38Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s10515-022-00333-1"}],"article_number":"35","alternative_title":["Revoking the preprocessor’s special role"],"doi":"10.1007/s10515-022-00333-1","citation":{"short":"P.

Diese Frage, die seit Jahrhunderten auf der Ebene der Logik, der Rhetorik und der Dialektik diskutiert wird, beschäftigt auch die moderne Sprachwissenschaft.

Eine neue Form der Kategorisierung und eine systematische Beschreibung der Vielfalt dieser Argumentationsindikatoren stehen im Zentrum der vorliegenden Studie. Die qualitative und quantitative Analyse ausgewählter Indikatoren des Deutschen und des Französischen gewährt neue Erkenntnisse im Bereich des Sprachvergleichs und der Übersetzungsforschung.
