Such structures can be fabricated through epitaxial lift-off using selective etching of Al-containing layers and subsequent transfer to glass substrates. Herein, the selective etching of (111)B-oriented AlxGa1−xAs sacrificial layers (10–50 nm thick) with different aluminum concentrations (x = 0.5–1.0) in 10\% hydrofluoric acid is investigated and compared with standard (100)-oriented structures. The thinner the sacrificial layer and the lower the aluminum content, the lower the lateral etch rate. For both orientations, the lateral etch rates are in the same order of magnitude, but some quantitative differences exist. Furthermore, the epitaxial lift-off, the transfer, and the nanopatterning of thin (111)B-oriented GaAs membranes are demonstrated. Atomic force microscopy and high-resolution X-ray diffraction measurements reveal the high structural quality of the transferred GaAs-(111) films.}}, author = {{Henksmeier, Tobias and Eppinger, Martin and Reineke, Bernhard and Zentgraf, Thomas and Meier, Cedrik and Reuter, Dirk}}, journal = {{physica status solidi (a)}}, keywords = {{epitaxial lift-off, GaAs/AlxGa1−xAs heterostructures, selective etching}}, number = {{3}}, pages = {{2000408}}, title = {{{Selective Etching of (111)B-Oriented AlxGa1−xAs-Layers for Epitaxial Lift-Off}}}, doi = {{https://doi.org/10.1002/pssa.202000408}}, volume = {{218}}, year = {{2021}}, } @inproceedings{20641, author = {{Aßmuth, Verena and Teutenberg, Dominik and Meschut, Gerson}}, booktitle = {{10.

Services consist of multiple interconnected components such as microservices in a service mesh. Coordinating these services requires scaling them according to continuously changing user demand, deploying instances at the edge close to their users, and routing traffic efficiently between users and connected instances. Network and service coordination is commonly addressed through centralized approaches, where a single coordinator knows everything and coordinates the entire network globally. While such centralized approaches can reach global optima, they do not scale to large, realistic networks. In contrast, distributed approaches scale well, but sacrifice solution quality due to their limited scope of knowledge and coordination decisions. To this end, we propose a hierarchical coordination approach that combines the good solution quality of centralized approaches with the scalability of distributed approaches. In doing so, we divide the network into multiple hierarchical domains and optimize coordination in a top-down manner. We compare our hierarchical with a centralized approach in an extensive evaluation on a real-world network topology. Our results indicate that hierarchical coordination can find close-to-optimal solutions in a fraction of the runtime of centralized approaches.}}, author = {{Schneider, Stefan Balthasar and Jürgens, Mirko and Karl, Holger}}, booktitle = {{IFIP/IEEE International Symposium on Integrated Network Management (IM)}}, keywords = {{network management, service management, coordination, hierarchical, scalability, nfv}}, location = {{Bordeaux, France}}, publisher = {{IFIP/IEEE}}, title = {{{Divide and Conquer: Hierarchical Network and Service Coordination}}}, year = {{2021}}, } @inproceedings{20817, author = {{Bienkowski, Marcin and Feldkord, Björn and Schmidt, Pawel}}, booktitle = {{Proceedings of the 38th Symposium on Theoretical Aspects of Computer Science (STACS)}}, pages = {{14:1 -- 14:17}}, title = {{{A Nearly Optimal Deterministic Online Algorithm for Non-Metric Facility Location}}}, doi = {{10.4230/LIPIcs.STACS.2021.14}}, year = {{2021}}, } @inproceedings{20857, author = {{Camberg, Alan Adam and Tröster, Thomas and Latuske, Clemens}}, location = {{Wolfsburg}}, publisher = {{Springer}}, title = {{{Development of a hybrid crash-relevant car body component with load-adapted thickness properties: Design, manufacturing and testing}}}, doi = {{https://doi.org/10.1007/978-3-662-62924-6_28}}, year = {{2021}}, } @inproceedings{20858, author = {{Camberg, Alan Adam and Tröster, Thomas and Wingenbach, Nils and Hielscher, Christian and Grenz, Julian}}, location = {{Wolfsburg}}, publisher = {{Springer}}, title = {{{A new numerical method for potential anaylsis and design of hybrid components from full vehicle simulations: Implementation and component design}}}, doi = {{https://doi.org/10.1007/978-3-662-62924-6_30}}, year = {{2021}}, } @inproceedings{20886, author = {{Nickchen, Tobias and Heindorf, Stefan and Engels, Gregor}}, booktitle = {{Proceedings of the IEEE/CVF Winter Conference on Applications of Computer Vision}}, location = {{Hawaii}}, pages = {{1994--2002}}, title = {{{Generating Physically Sound Training Data for Image Recognition of Additively Manufactured Parts}}}, year = {{2021}}, } @article{20900, author = {{Albert, M. and Golla, C. and Meier, Cedrik}}, issn = {{0022-0248}}, journal = {{Journal of Crystal Growth}}, title = {{{Optical in-situ temperature management for high-quality ZnO molecular beam epitaxy}}}, doi = {{10.1016/j.jcrysgro.2020.126009}}, volume = {{557}}, year = {{2021}}, } @article{20925, author = {{Abbas, Wameedh Khider Abbas and Linnemann, Matthias and Baumhögger, Elmar and Vrabec, Jadran}}, issn = {{0196-8904}}, journal = {{Energy Conversion and Management}}, title = {{{Experimental study of two cascaded organic Rankine cycles with varying working fluids}}}, doi = {{10.1016/j.enconman.2020.113818}}, year = {{2021}}, } @inproceedings{22155, author = {{Gottschalk, Sebastian}}, booktitle = {{Advanced Software Engineering.

Metrics such as ECT, RNSB, and WEAT quantify bias in these models based on predefined word lists representing social groups and bias-conveying concepts. How suitable these lists actually are to reveal bias - let alone the bias metrics in general - remains unclear, though. In this paper, we study how to assess the quality of bias metrics for word embedding models. In particular, we present a generic method, Bias Silhouette Analysis (BSA), that quantifies the accuracy and robustness of such a metric and of the word lists used. Given a biased and an unbiased reference embedding model, BSA applies the metric systematically for several subsets of the lists to the models. The variance and rate of convergence of the bias values of each model then entail the robustness of the word lists, whereas the distance between the models' values gives indications of the general accuracy of the metric with the word lists. We demonstrate the behavior of BSA on two standard embedding models for the three mentioned metrics with several word lists from existing research.}}, author = {{Spliethöver, Maximilian and Wachsmuth, Henning}}, booktitle = {{Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, IJCAI-21}}, location = {{Online}}, pages = {{552--559}}, title = {{{Bias Silhouette Analysis: Towards Assessing the Quality of Bias Metrics for Word Embedding Models}}}, doi = {{10.24963/ijcai.2021/77}}, year = {{2021}}, } @inproceedings{22158, author = {{Syed, Shahbaz and Al-Khatib, Khalid and Alshomary, Milad and Wachsmuth, Henning and Potthast, Martin}}, booktitle = {{Proceedings of the Joint Conference of the 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing (ACL-IJCNLP 2021): Findings}}, pages = {{3482--3493}}, title = {{{Generating Informative Conclusions for Argumentative Texts}}}, year = {{2021}}, } @inproceedings{22159, author = {{Barrow, Joe and Jain, Rajiv and Lipka, Nedim and Dernoncourt, Franck and Morariu, Vlad and Manjunatha, Varun and Oard, Douglas and Resnik, Philip and Wachsmuth, Henning}}, booktitle = {{Proceedings of the Joint Conference of the 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing (ACL-IJCNLP 2021)}}, pages = {{1583--1595}}, title = {{{Syntopical Graphs for Computational Argumentation Tasks}}}, year = {{2021}}, }
