--- _id: '45361' abstract: - lang: eng text: The non-orthogonal local submatrix method applied to electronic structure–based molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32-mixed floating-point arithmetic when using 4400 NVIDIA A100 GPUs of the Perlmutter system. This is enabled by a modification of the original method that pushes the sustained fraction of the peak performance to about 80%. Example calculations are performed for SARS-CoV-2 spike proteins with up to 83 million atoms. article_number: '109434202311776' article_type: original author: - first_name: Robert full_name: Schade, Robert id: '75963' last_name: Schade orcid: 0000-0002-6268-539 - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter - first_name: Hossam full_name: Elgabarty, Hossam id: '60250' last_name: Elgabarty orcid: 0000-0002-4945-1481 - first_name: Michael full_name: Lass, Michael id: '24135' last_name: Lass orcid: 0000-0002-5708-7632 - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 citation: ama: Schade R, Kenter T, Elgabarty H, Lass M, Kühne T, Plessl C.

The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step under As flux. In order to model the complex process, including the masked deposition of the droplets and a reduction of their number during a thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition. The simulation has only two free model parameters: the activation energy for surface diffusion and the activation energy for thermal escape of adatoms from a droplet. Simulated droplet numbers within the opening of the aperture agree quantitatively with the experimental results down to the perfect site-control, with one droplet per aperture. However, the model parameters are different compared to those of the self-assembled droplet growth. We attribute this to the presence of the mask in close proximity to the surface, which modifies the local process temperature and the As background. This approach also explains the dependence of the model parameters on the size of the aperture.' article_number: '466' author: - first_name: Stefan full_name: Feddersen, Stefan last_name: Feddersen - first_name: Viktoryia full_name: Zolatanosha, Viktoryia last_name: Zolatanosha - first_name: Ahmed full_name: Alshaikh, Ahmed last_name: Alshaikh - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Christian full_name: Heyn, Christian last_name: Heyn citation: ama: Feddersen S, Zolatanosha V, Alshaikh A, Reuter D, Heyn C.

For a more sustainable future, development of competitive base metal dyads is mandatory. However, the electron transfer mechanisms from the photosensitizer to the proton reduction catalyst in base metal dyads remain so far unexplored. We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy and theoretical time-dependent DFT calculations, to understand the electronic and structural dynamics after photoexcitation and during the subsequent charge transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using this novel approach, the simultaneous measurement of the transient Kalpha X-ray emission at the iron and cobalt K-edges in a two-colour experiment is enabled making it possible to correlate the excited state dynamics to the electron transfer processes. The methodology, therefore, provides a clear and direct spectroscopic evidence of the Fe->Co electron transfer responsible for the proton reduction activity. author: - first_name: Michał full_name: Nowakowski, Michał id: '78878' last_name: Nowakowski orcid: 0000-0002-3734-7011 - first_name: Marina full_name: Huber-Gedert, Marina id: '38352' last_name: Huber-Gedert - first_name: Hossam full_name: Elgabarty, Hossam id: '60250' last_name: Elgabarty orcid: 0000-0002-4945-1481 - first_name: Jacek full_name: Kubicki, Jacek last_name: Kubicki - first_name: Ahmet full_name: Kertem, Ahmet last_name: Kertem - first_name: Natalia full_name: Lindner, Natalia last_name: Lindner - first_name: Dimitry full_name: Khakhulin, Dimitry last_name: Khakhulin - first_name: Frederico Alves full_name: Lima, Frederico Alves last_name: Lima - first_name: Tae-Kyu full_name: Choi, Tae-Kyu last_name: Choi - first_name: Mykola full_name: Biednov, Mykola last_name: Biednov - first_name: Natalia full_name: Piergies, Natalia last_name: Piergies - first_name: Peter full_name: Zalden, Peter last_name: Zalden - first_name: Katerina full_name: Kubicek, Katerina last_name: Kubicek - first_name: Angel full_name: Rodriguez-Fernandez, Angel last_name: Rodriguez-Fernandez - first_name: Mohammad Alaraby full_name: Salem, Mohammad Alaraby last_name: Salem - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne - first_name: Wojciech full_name: Gawelda, Wojciech last_name: Gawelda - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 citation: ama: Nowakowski M, Huber-Gedert M, Elgabarty H, et al.

It says that among all possible motions connecting two points in a phase space, the system will exhibit those motions which extremise an action functional. Many qualitative features of dynamical systems, such as the presence of conservation laws and energy balance equations, are related to the existence of an action functional. Incorporating variational structure into learning algorithms for dynamical systems is, therefore, crucial in order to make sure that the learned model shares important features with the exact physical system. In this paper we show how to incorporate variational principles into trajectory predictions of learned dynamical systems. The novelty of this work is that (1) our technique relies only on discrete position data of observed trajectories. Velocities or conjugate momenta do not need to be observed or approximated and no prior knowledge about the form of the variational principle is assumed. Instead, they are recovered using backward error analysis. (2) Moreover, our technique compensates discretisation errors when trajectories are computed from the learned system. This is important when moderate to large step-sizes are used and high accuracy is required.

It says that among all possible motions connecting two points in a phase space, the system will exhibit those motions which extremise an action functional. Many qualitative features of dynamical systems, such as the presence of conservation laws and energy balance equa- tions, are related to the existence of an action functional. Incorporating variational structure into learning algorithms for dynamical systems is, therefore, crucial in order to make sure that the learned model shares important features with the exact physical system. In this paper we show how to incorporate variational principles into trajectory predic- tions of learned dynamical systems. The novelty of this work is that (1) our technique relies only on discrete position data of observed trajectories. Velocities or conjugate momenta do not need to be observed or approximated and no prior knowledge about the form of the variational principle is assumed. Instead, they are recovered using backward error analysis. (2) Moreover, our technique compensates discretisation errors when trajectories are computed from the learned system. This is important when moderate to large step-sizes are used and high accuracy is required. For this, we introduce and rigorously analyse the concept of inverse modified Lagrangians by developing an inverse version of variational backward error analysis. (3) Finally, we introduce a method to perform system identification from position observations only, based on variational backward error analysis. file_id: '32274' file_name: ShadowLagrangian_revision1_journal_style_arxiv.pdf file_size: 3640770 relation: main_file title: Variational Learning of Euler–Lagrange Dynamics from Data file_date_updated: 2022-06-28T15:25:50Z has_accepted_license: '1' intvolume: ' 421' keyword: - Lagrangian learning - variational backward error analysis - modified Lagrangian - variational integrators - physics informed learning language: - iso: eng oa: '1' page: '114780' publication: Journal of Computational and Applied Mathematics publication_identifier: issn: - 0377-0427 publication_status: epub_ahead publisher: Elsevier quality_controlled: '1' related_material: link: - relation: software url: https://github.com/Christian-Offen/LagrangianShadowIntegration status: public title: Variational Learning of Euler–Lagrange Dynamics from Data type: journal_article user_id: '85279' volume: 421 year: '2023' ... --- _id: '29236' abstract: - lang: eng text: The numerical solution of an ordinary differential equation can be interpreted as the exact solution of a nearby modified equation.

Increasing resource efficiency is a major challenge and affects almost every aspect of social and economic life. The mobility sector in particular is responsible for a large share of primary energy consumption and is increasingly in the focus of public interest. One possibility to adress these challenges is to reduce the vehicle weight by means of lightweight construction technologies such as multi-material systems. These assemblies consist of workpieces with different mechanical and geometrical properties, which poses a major challenge for joining technology. Mechanical joining processes such as semi-tubular self-piercing riveting are often used in the production of these assemblies, but due to their process characteristics, they are rigid and can only react to changing process variables to a limited extent. One way to increase the versatility of self-piercing riveting is to superimpose a tumbling kinematics on the punch. During tumbling, an angular offset of the punch axis to the tool axis is set and the contact area between punch and workpiece is reduced. In this work, investigations were carried out to determine how the tumbling strategy, consisting of the parameters tumbling angle, tumbling onset and tumbling kinematics, affects the material flow of the rivet element. For this purpose, experimental tests are conducted with the typical materials of conventional multi-material systems and the geometric joint formations are determined by means of macrographs. author: - first_name: S. full_name: Wituschek, S. last_name: Wituschek - first_name: L. full_name: Elbel, L. last_name: Elbel - first_name: M. full_name: Lechner, M. last_name: Lechner citation: ama: 'Wituschek S, Elbel L, Lechner M.

Complex applications with high demands on safety and reliability, such as autonomous driving, are simultaneously driving the requirements for test and diagnosis of VLSI circuits. Throughout the life cycle of a microchip, uncertainties occur that affect its timing behavior. For example, weak circuit structures, aging effects, or process variations can lead to a change in the timing behavior of the circuit. While these uncertainties do not necessarily lead to a change of the functional behavior, they can lead to a reliability problem.\r\nWith modular and hybrid compaction two test instruments are presented in this work that can be used for X-tolerant test response compaction in the built-in Faster-than-At-Speed Test (FAST) which is used to detect uncertainties in VLSI circuits. One challenge for test response compaction during FAST is the high and varying X-rate at the outputs of the circuit under test. By dividing the circuit outputs into test groups and separately compacting these test groups using stochastic compactors, the modular compaction is able to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic interconnects, a method for distinguishing crosstalk and process variation is presented. In current semiconductor technologies, the number of parasitic coupling capacitances between logic interconnects is growing. These coupling capacitances can lead to crosstalk, which causes increased current flow in the logic interconnects, which in turn can lead to increased electromigration. In the presented method, delay maps describing the timing behavior of the circuit outputs at different operating points are used to train artificial neural networks which classify the tested circuits into fault-free and faulty." - lang: ger text: "Immer größere Anforderungen an die Leistungsfähigkeit von Mikrochips führen zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen. Anwendungen mit hohen Ansprüchen an Sicherheit und Zuverlässigkeit, wie z.B. das autonome Fahren, treiben gleichzeitig die Anforderungen an den Test hochintegrierter Schaltungen an. Während des gesamten Lebenszyklus eines Mikrochips kommt es zu Unsicherheiten im Zeitverhalten. So können z.B. schwache Schaltungsstrukturen, Alterungseffekte oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und Prozessvariation vorgestellt.

This study could lead to the successful processing of squirrel cage conductors (a lattice structure by design) of an induction motor by additive manufacturing in the future.\r\n\r\n\r\nDesign/methodology/approach\r\nThe compression behaviour of two lattice structures where struts are arranged in a face-centred cubic position and vertical edges (FCCZ), and struts are placed at body-centred cubic (BCC) positions, prepared by laser powder bed fusion (LPBF), is explored. The experimental investigations are supported by finite element method (FEM) simulations.\r\n\r\n\r\nFindings\r\nThe FCCZ lattice structure presents a peak in the stress-strain curve, whereas the BCC lattice structure manifests a plateau. The vertical struts aligned along the compression direction lead to a significant increase in the load-carrying ability of FCCZ lattice structures compared to BCC lattice structures. This results in a peak in the stress-strain curve. However, the BCC lattice structure presents the bending of struts with diagonal struts carrying the major loads with struts near the faceplate receiving the least load. A high concentration of geometrically necessary dislocations (GNDs) near the grain boundaries along cell formation is observed in the microstructure.\r\n\r\n\r\nOriginality/value\r\nTo the best of the authors’ knowledge, this is the first study on additive manufacturing of Fe-3Si lattice structures. Currently, there are no investigations in the literature on the manufacturability and mechanical properties of Fe-3Si lattice structures.\r\n" author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Pramanik S, Hoyer K-P, Schaper M.

Geospatial link discovery algorithms have to deal with millions of point sets containing billions of points. \r\nMethodology: To speed up the discovery of geospatial links, we propose COBALT. COBALT combines the content measures with R-tree indexing. The content measures are based on the area, diagonal and distance of the minimum bounding boxes of the polygons which speeds up the process but is not perfectly accurate. We thus propose two polygon splitting approaches for improving the accuracy of COBALT. \r\nFindings: Our experiments on real-world datasets show that COBALT is able to speed up the topological relation discovery over geospatial KGs by up to 1.47 × 104 times over state-of-the-art linking algorithms while maintaining an F-Measure between 0.7 and 0.9 depending on the relation. Furthermore, we were able to achieve an F-Measure of up to 0.99 by applying our polygon splitting approaches before applying the content measures. \r\nValue: The process of discovering links between geospatial resources can be significantly faster by sacrificing the optimality of the results. This is especially important for real time data-driven applications such as emergency response, location-based services and traffic management. In future work, additional measures, like the location of polygons or the name of the entity represented by the polygon, could be integrated to further improve the accuracy of the results." author: - first_name: Alexander full_name: Becker, Alexander last_name: Becker - first_name: Abdullah Fathi Ahmed full_name: Ahmed, Abdullah Fathi Ahmed id: '29670' last_name: Ahmed - first_name: Mohamed full_name: Sherif, Mohamed id: '67234' last_name: Sherif orcid: https://orcid.org/0000-0002-9927-2203 - first_name: Axel-Cyrille full_name: Ngonga Ngomo, Axel-Cyrille id: '65716' last_name: Ngonga Ngomo citation: ama: 'Becker A, Ahmed AFA, Sherif M, Ngonga Ngomo A-C.

Declarative link discovery frameworks use complex link specifications to express the conditions under which a link between two resources can be deemed to exist. However, understanding such complex link specifications is a challenging task for non-expert users of link discovery frameworks. In this paper, we address this drawback by devising NMV-LS, a language model-based verbalization approach for translating complex link specifications into natural language. NMV-LS relies on the results of rule-based link specification verbalization to apply continuous training on T5, a large language model based on the Transformerarchitecture. We evaluated NMV-LS on English and German datasets using well-known machine translation metrics such as BLUE, METEOR, ChrF++ and TER. Our results suggest that our approach achieves a verbalization performance close to that of humans and outperforms state of the art approaches.

We performed several experiments to assess the quality of generated summaries by language models. In particular, we evaluated the generated summaries using human judgments and automated metrics (Self-ROUGE and BERTScore). Additionally, we studied the correlation between human judgments and automated metrics in evaluating the generated summaries under different aspects: informativeness, coherence, conciseness, and fluency.\r\nFindings: Pre-trained language models generate summaries more concise and informative than existing short abstracts. Specifically, BART-based models effectively overcome the limitations of DBpedia short abstracts, especially for longer ones.\r\nMoreover, we show that BERTScore and ROUGE-1 are reliable metrics for assessing the informativeness and coherence of the generated summaries with respect to the full DBpedia abstracts. We also find a negative correlation between conciseness and human ratings. Furthermore, fluency evaluation remains challenging without human judgment.\r\nValue: This study has significant implications for various applications in machine learning and natural language processing that rely on DBpedia resources.

To the best of our knowledge, no suitable data corpora are available for systematic research until now. The Information System Graffiti in Germany project (Ingrid) closes this gap by dealing with graffiti image collections that have been made available to the project for public use. Within Ingrid, the graffiti images are collected, digitized and annotated. With this work, we aim to support the rapid access to a comprehensive data source on Ingrid targeted especially by researchers. In particular, we present IngridKG, an RDF knowledge graph of annotated graffiti, abides by the Linked Data and FAIR principles. We weekly update IngridKG by augmenting the new annotated graffiti to our knowledge graph. Our generation pipeline applies RDF data conversion, link discovery and data fusion approaches to the original data. The current version of IngridKG contains 460,640,154 triples and is linked to 3 other knowledge graphs by over 200,000 links.

In this work, multiprotein adsorption from diluted human serum at gold and oxidized iron surfaces is investigated at different serum concentrations and pH values. Adsorption-induced changes in surface topography and the total amount of adsorbed proteins are quantified by atomic force microscopy (AFM) and polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS), respectively. For both surfaces, stronger protein adsorption is observed at pH 6 compared to pH 7 and pH 8. PM-IRRAS furthermore provides some qualitative insights into the pH-dependent alterations in the composition of the adsorbed multiprotein films. Changes in the amide II/amide I band area ratio and in particular side-chain IR absorption suggest that the increased adsorption at pH 6 is accompanied by a change in protein film composition. Presumably, this is mostly driven by the adsorption of human serum albumin, which at pH 6 adsorbs more readily and thereby replaces other proteins with lower surface affinities in the resulting multiprotein film. article_number: '6060' author: - first_name: Jingyuan full_name: Huang, Jingyuan last_name: Huang - first_name: Yunshu full_name: Qiu, Yunshu last_name: Qiu - first_name: Felix full_name: Lücke, Felix last_name: Lücke - first_name: Jiangling full_name: Su, Jiangling last_name: Su - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Huang J, Qiu Y, Lücke F, Su J, Grundmeier G, Keller A.

Herein, ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces is investigated using atomic force microscopy and X-ray photoelectron spectroscopy. The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like surface topographies with periodicities of about 160 nm and amplitudes of about 15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed compared to the flat surface at a concentration of 10 mg/mL, which is attributed to lower adsorption affinities of the newly formed facets. Consequently, adsorption is restricted mostly to the pattern grooves, where the proteins can maximize their contact area with the surface. However, this effect depends on the protein concentration, with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin adsorption behavior is observed at topographically similar nanofacet patterns fabricated at different annealing temperatures and attributed to different step and kink densities. These results demonstrate that while protein adsorption at solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein adsorption in this way requires the precise control of facet properties. article_number: '12808' author: - first_name: Bhanu K. full_name: Pothineni, Bhanu K. last_name: Pothineni - first_name: Sabrina full_name: Kollmann, Sabrina last_name: Kollmann - first_name: Xinyang full_name: Li, Xinyang last_name: Li - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Denise J. full_name: Erb, Denise J. last_name: Erb - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Pothineni BK, Kollmann S, Li X, Grundmeier G, Erb DJ, Keller A.

The paucity of datasets is recognized as the main reason for the slow advancements in NLP research for underrepresented languages. Significant attempts were made in 2020 to address this drawback for Indonesian. The Indonesian Natural Language Understanding (IndoNLU) benchmark was introduced alongside IndoBERT pre-trained language model. The second benchmark, Indonesian Language Evaluation Montage (IndoLEM), was presented in the same year. These benchmarks support several tasks, including Named Entity Recognition (NER). However, all NER datasets are in the public domain and do not contain domain-specific datasets. To alleviate this drawback, we introduce IndQNER, a manually annotated NER benchmark dataset in the religious domain that adheres to a meticulously designed annotation guideline. Since Indonesia has the world’s largest Muslim population, we build the dataset from the Indonesian translation of the Quran. The dataset includes 2475 named entities representing 18 different classes. To assess the annotation quality of IndQNER, we perform experiments with BiLSTM and CRF-based NER, as well as IndoBERT fine-tuning. The results reveal that the first model outperforms the second model achieving 0.98 F1 points. This outcome indicates that IndQNER may be an acceptable evaluation metric for Indonesian NER tasks in the aforementioned domain, widening the research’s domain range. author: - first_name: Ria Hari full_name: Gusmita, Ria Hari last_name: Gusmita - first_name: Asep Fajar full_name: Firmansyah, Asep Fajar last_name: Firmansyah - first_name: Diego full_name: Moussallem, Diego last_name: Moussallem - first_name: Axel-Cyrille full_name: Ngonga Ngomo, Axel-Cyrille last_name: Ngonga Ngomo citation: ama: 'Gusmita RH, Firmansyah AF, Moussallem D, Ngonga Ngomo A-C.

As external visualization is an important part of mathematics at all levels of education, it is diverse, and research on external visualization has become a wide and complex field. The aim of this scoping review is to characterize external visualizations in recent mathematics education research in order to develop a common ground and guide future research. A qualitative content analysis of the full texts of 130 studies published between 2018 and 2022 applied a deductive-inductive coding procedure to assess four dimensions: visualization product or process, type of visualization, media, and purpose. The analysis revealed different types of external visualizations including visualizations with physical resemblance ranging from pictorial to abstract visualizations as well as three types of visualizations with structural resemblance: length, area, and relational visualizations. Future research should include measures of visualization products or processes to help explain the demands and affordances that different types of visualizations present to learners and teachers.' author: - first_name: Johanna full_name: Schoenherr, Johanna last_name: Schoenherr - first_name: Stanislaw full_name: Schukajlow, Stanislaw last_name: Schukajlow citation: ama: 'Schoenherr J, Schukajlow S.
