Typically, bulky pulse compressors consisting of gratings or prisms are used\r\nto address this issue by precompensating the dispersion of the optical components. However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse."}],"date_created":"2023-04-18T05:47:22Z","publisher":"American Chemical Society (ACS)","title":"Compact Metasurface-Based Optical Pulse-Shaping Device","issue":"8","quality_controlled":"1","year":"2023","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - B09: TRR 142 - Subproject B09","_id":"170"},{"name":"TRR 142 - C07: TRR 142 - Subproject C07","_id":"171"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"}],"_id":"44044","file_date_updated":"2023-04-18T05:50:19Z","funded_apc":"1","article_type":"original","type":"journal_article","status":"public","author":[{"first_name":"René","last_name":"Geromel","full_name":"Geromel, René"},{"full_name":"Georgi, Philip","last_name":"Georgi","first_name":"Philip"},{"last_name":"Protte","id":"46170","full_name":"Protte, Maximilian","first_name":"Maximilian"},{"first_name":"Shiwei","full_name":"Lei, Shiwei","last_name":"Lei"},{"last_name":"Bartley","full_name":"Bartley, Tim","id":"49683","first_name":"Tim"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"},{"last_name":"Zentgraf","orcid":"0000-0002-8662-1101","id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas"}],"volume":23,"date_updated":"2023-05-12T11:17:51Z","oa":"1","main_file_link":[{"url":"https://pubs.acs.org/doi/full/10.1021/acs.nanolett.2c04980","open_access":"1"}],"doi":"10.1021/acs.nanolett.2c04980","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["1530-6984","1530-6992"]},"citation":{"ieee":"R.

HTC of different saccharides is known to produce microspheres (MS) with mostly Gaussian size distribution, which are utilized as functional materials in various applications, both as pristine MS and as a precursor for hard carbon MS. Although the average size of the MS can be influenced by adjusting the process parameters, there is no reliable mechanism to affect their size distribution. Our results demonstrate that HTC of trehalose, in contrast to other saccharides, results in a distinctly bimodal sphere diameter distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic post-carbonization at 1000 °C the MS develop a multimodal pore size distribution with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which were examined by small-angle X-ray scattering and visualized by charge-compensated helium ion microscopy. The bimodal size distribution and hierarchical porosity provide an extraordinary set of properties and potential variables for the tailored synthesis of hierarchical porous carbons, making trehalose-derived hard carbon MS a highly promising material for applications in catalysis, filtration, and energy storage devices.","lang":"eng"}],"keyword":["General Chemical Engineering","General Chemistry"],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"21","year":"2023","publisher":"Royal Society of Chemistry (RSC)","date_created":"2023-05-12T07:16:15Z","title":"Hard carbon microspheres with bimodal size distribution and hierarchical porosity <i>via</i> hydrothermal carbonization of trehalose"},{"title":"Improved determination of viscoelastic material parameters using a pulse-echo measurement setup","date_created":"2023-05-23T09:31:28Z","publisher":"AMA Association For Sensors And Measurement","year":"2023","language":[{"iso":"eng"}],"ddc":["620"],"file":[{"creator":"dmitrij","date_created":"2023-05-23T09:26:40Z","date_updated":"2023-05-23T09:26:40Z","access_level":"closed","file_name":"P59.pdf","file_id":"45207","file_size":686417,"content_type":"application/pdf","relation":"main_file","success":1}],"publication":"SMSI 2023 Conference","conference":{"start_date":"2023-05-08","name":"SMSI 2023 - Conference","location":"Nürnberg","end_date":"2023-05-11"},"doi":"10.5162/SMSI2023/P59","main_file_link":[{"open_access":"1"}],"author":[{"last_name":"Dreiling","full_name":"Dreiling, Dmitrij","id":"32616","first_name":"Dmitrij"},{"full_name":"Itner, Dominik","last_name":"Itner","first_name":"Dominik"},{"first_name":"Tim","full_name":"Hetkämper, Tim","id":"38123","last_name":"Hetkämper"},{"full_name":"Birk, Carolin","last_name":"Birk","first_name":"Carolin"},{"full_name":"Gravenkamp, Hauke","last_name":"Gravenkamp","first_name":"Hauke"},{"first_name":"Bernd","last_name":"Henning","id":"213","full_name":"Henning, Bernd"}],"date_updated":"2023-05-23T12:02:26Z","oa":"1","page":"394 - 395","citation":{"apa":"Dreiling, D., Itner, D., Hetkämper, T., Birk, C., Gravenkamp, H., &#38; Henning, B.

Tailoring phase and amplitude of a nonlinearly generated wave with a high emission efficiency using resonance-based metasurfaces is a challenging task that often requires state-of-the-art numerical methods. Here, we propose a simple yet effective approach combining a sampling method with a Monte Carlo approach to design the third-harmonic wavefront generated by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using this approach, we theoretically demonstrate the full nonlinear 2π phase control with a uniform and highest possible amplitude in the considered parameter space, allowing us to design metasurfaces operating as third harmonic beam deflectors capable of steering light into a desired direction with high emission efficiency. The TH beam deflection with a record calculated average conversion efficiency of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be widely applied as alternative to commonly used optimization algorithms with higher complexity and implementation effort for the design of metasurfaces with other holographic functionalities.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":5382111,"file_name":"2023-06 Hähnel - ACS Photonics - Efficient Modeling and Tailoring of Nonlinear Wavefronts in Dielectric Metasurfaces.pdf","access_level":"open_access","file_id":"45597","date_updated":"2023-06-13T09:48:17Z","creator":"fossie","date_created":"2023-06-13T09:48:17Z"}],"ddc":["530"],"keyword":["tet_topic_meta"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2330-4022","2330-4022"]},"has_accepted_license":"1","citation":{"ieee":"D.

Conductive two-dimensional frameworks (2D MOFs) with a fast ion transport can combine both - charge transfer and fast diffusion inside their porous structure. To study remaining diffusion limitations caused by particle morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene (Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF particles. Both morphologies are systematically characterized and evaluated for redox-active Li+ ion storage. The redox mechanism is investigated by means of X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry and impedance spectroscopy. A significant influence of particle morphology for 2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed. This study opens the path for optimization of redox active porous structures to overcome diffusion limitations of Faradaic processes."}]},{"title":"Navigationen: Tech | Demo","main_file_link":[{"url":"https://dspace.ub.uni-siegen.de/bitstream/ubsi/2490/3/TechDemo_Navigationen_1_2023.pdf","open_access":"1"}],"date_updated":"2023-06-22T14:57:49Z","oa":"1","date_created":"2023-01-15T11:15:39Z","volume":23,"year":"2023","citation":{"mla":"Eckel, Julia, et al., editors. “Navigationen: Tech | Demo.” <i>Navigationen - Zeitschrift Für Medien- Und Kulturwissenschaften</i>, vol. 23, no. 1, 2023.","short":"J.

Life Cycle Engineering (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic information and improvement potentials regarding eco-efficient products. Key factors influencing LCAs of automotive components, such as material production, will change in the future. First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles. This work contributes to the methodological and practical integration of pLCA into automotive development processes and provides quantitative results.</jats:p>"}]},{"_id":"31880","user_id":"44040","language":[{"iso":"eng"}],"type":"conference","publication":"International Conference on Learning Representations, ICLR","abstract":[{"text":"The notion of neural collapse refers to several emergent phenomena that have been empirically observed across various canonical classification problems. During the terminal phase of training a deep neural network, the feature embedding of all examples of the same class tend to collapse to a single representation, and the features of different classes tend to separate as much as possible. Neural collapse is often studied through a simplified model, called the unconstrained feature representation, in which the model is assumed to have \"infinite expressivity\" and can map each data point to any arbitrary representation. In this work, we propose a more realistic variant of the unconstrained feature representation that takes the limited expressivity of the network into account. Empirical evidence suggests that the memorization of noisy data points leads to a degradation (dilation) of the neural collapse. Using a model of the memorization-dilation (M-D) phenomenon, we show one mechanism by which different losses lead to different performances of the trained network on noisy data. Our proofs reveal why label smoothing, a modification of cross-entropy empirically observed to produce a regularization effect, leads to improved generalization in classification tasks.","lang":"eng"}],"status":"public","oa":"1","date_updated":"2023-06-29T09:14:26Z","author":[{"last_name":"Nguyen","full_name":"Nguyen, Duc Anh","first_name":"Duc Anh"},{"last_name":"Levie","full_name":"Levie, Ron","first_name":"Ron"},{"last_name":"Lienen","full_name":"Lienen, Julian","id":"44040","first_name":"Julian"},{"full_name":"Kutyniok, Gitta","last_name":"Kutyniok","first_name":"Gitta"},{"first_name":"Eyke","last_name":"Hüllermeier","full_name":"Hüllermeier, Eyke","id":"48129"}],"date_created":"2022-06-14T14:48:36Z","title":"Memorization-Dilation: Modeling Neural Collapse Under Noise","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2206.05530"}],"conference":{"name":"International Conference on Learning Representations, ICLR","location":"Kigali, Ruanda"},"year":"2023","citation":{"apa":"Nguyen, D.

Models of that kind are prone to memorizing incorrect labels, thereby\r\nharming generalization performance. Many methods have been proposed to address\r\nthis problem, including robust loss functions and more complex label correction\r\napproaches. Robust loss functions are appealing due to their simplicity, but\r\ntypically lack flexibility, while label correction usually adds substantial\r\ncomplexity to the training setup. In this paper, we suggest to address the\r\nshortcomings of both methodologies by \"ambiguating\" the target information,\r\nadding additional, complementary candidate labels in case the learner is not\r\nsufficiently convinced of the observed training label. More precisely, we\r\nleverage the framework of so-called superset learning to construct set-valued\r\ntargets based on a confidence threshold, which deliver imprecise yet more\r\nreliable beliefs about the ground-truth, effectively helping the learner to\r\nsuppress the memorization effect. In an extensive empirical evaluation, our\r\nmethod demonstrates favorable learning behavior on synthetic and real-world\r\nnoise, confirming the effectiveness in detecting and correcting erroneous\r\ntraining labels.","lang":"eng"}]},{"external_id":{"unknown":["https://link.springer.com/chapter/10.1007/978-3-031-33455-9_13"]},"language":[{"iso":"eng"}],"keyword":["Neural network","Concept learning","Description logics"],"publication":"The Semantic Web - 20th Extended Semantic Web Conference (ESWC 2023)","abstract":[{"lang":"eng","text":"Many applications require explainable node classification in knowledge graphs. Towards this end, a popular ``white-box'' approach is class expression learning: Given sets of positive and negative nodes, class expressions in description logics are learned that separate positive from negative nodes. Most existing approaches are search-based approaches generating many candidate class expressions and selecting the best one. However, they often take a long time to find suitable class expressions. In this paper, we cast class expression learning as a translation problem and propose a new family of class expression learning approaches which we dub neural class expression synthesizers. Training examples are ``translated'' into class expressions in a fashion akin to machine translation. Consequently, our synthesizers are not subject to the runtime limitations of search-based approaches. We study three instances of this novel family of approaches based on LSTMs, GRUs, and set transformers, respectively. An evaluation of our approach on four benchmark datasets suggests that it can effectively synthesize high-quality class expressions with respect to the input examples in approximately one second on average. Moreover, a comparison to state-of-the-art approaches suggests that we achieve better F-measures on large datasets.
