These services can scale and run across multiple network nodes on demand. To process incoming traffic, service components have to be instantiated and traffic assigned to these instances, taking capacities, changing demands, and Quality of Service (QoS) requirements into account. This challenge is usually solved with custom approaches designed by experts. While this typically works well for the considered scenario, the models often rely on unrealistic assumptions or on knowledge that is not available in practice (e.g., a priori knowledge).\r\n\r\nWe propose DeepCoord, a novel deep reinforcement learning approach that learns how to best coordinate services and is geared towards realistic assumptions. It interacts with the network and relies on available, possibly delayed monitoring information. Rather than defining a complex model or an algorithm on how to achieve an objective, our model-free approach adapts to various objectives and traffic patterns. An agent is trained offline without expert knowledge and then applied online with minimal overhead. Compared to a state-of-the-art heuristic, DeepCoord significantly improves flow throughput (up to 76%) and overall network utility (more than 2x) on realworld network topologies and traffic traces. It also supports optimizing multiple, possibly competing objectives, learns to respect QoS requirements, generalizes to scenarios with unseen, stochastic traffic, and scales to large real-world networks. For reproducibility and reuse, our code is publicly available.","lang":"eng"}],"publication":"Transactions on Network and Service Management","department":[{"_id":"75"}],"keyword":["network management","service management","coordination","reinforcement learning","self-learning","self-adaptation","multi-objective"],"type":"journal_article","date_created":"2021-04-27T08:04:16Z","file":[{"file_id":"21809","content_type":"application/pdf","relation":"main_file","date_updated":"2021-04-27T08:01:26Z","file_name":"ris-accepted-version.pdf","file_size":4172270,"access_level":"open_access","description":"Author version of the accepted paper","date_created":"2021-04-27T08:01:26Z","creator":"stschn"}],"article_type":"original","date_updated":"2022-01-06T06:55:15Z","author":[{"id":"35343","first_name":"Stefan Balthasar","orcid":"0000-0001-8210-4011","last_name":"Schneider","full_name":"Schneider, Stefan Balthasar"},{"last_name":"Khalili","first_name":"Ramin","full_name":"Khalili, Ramin"},{"first_name":"Adnan","last_name":"Manzoor","full_name":"Manzoor, Adnan"},{"last_name":"Qarawlus","first_name":"Haydar","full_name":"Qarawlus, Haydar"},{"full_name":"Schellenberg, Rafael","last_name":"Schellenberg","first_name":"Rafael"},{"first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger","id":"126"},{"first_name":"Artur","last_name":"Hecker","full_name":"Hecker, Artur"}],"year":"2021","title":"Self-Learning Multi-Objective Service Coordination Using Deep Reinforcement Learning","doi":"10.1109/TNSM.2021.3076503","language":[{"iso":"eng"}]},{"oa":"1","quality_controlled":"1","citation":{"mla":"Goller, Michael, and Simone Ziegler. “Zum Zusammenhang von Berufsethos und der Berufswahlmotivation angehender Wirtschaftspädagog*innen.” <i>bwp@ Spezial</i>, vol. 18, 2021, pp. 1–28.","ama":"Goller M, Ziegler S.

Während die Berufswahlmotivation bereits verstärkt im wirtschaftspädagogischen Kontext untersucht wurde, existieren zum Berufsethos von Wirtschaftspädagog*innen nur vereinzelt empirische Studien. So ist beispielsweise wenig darüber bekannt, wie das Berufsethos von Wirtschaftspädagog*innen in der Ausbildungsphase ausgeprägt ist. Auch die Erforschung des Zusammenhangs zwischen den Konstrukten des Berufsethos und der Berufswahlmotivation blieb bisher unbeachtet. In diesem Beitrag wird entsprechend dieses Forschungsdesiderats untersucht, wie das anfänglich ausgebildete Berufsethos von Wirtschaftspädagogikstudierenden in der universitären Ausbildung ausgeprägt ist, ob sich die Ausprägung nach dem angegebenen Berufswunsch der Studierenden unterscheidet und inwiefern das anfänglich ausgeprägte Berufsethos mit der Berufswahlmotivation von Studierenden zusammenhängt. Dafür wurden im Wintersemester 2019/20 an zwölf deutschen Universitäten insgesamt 879 Wirtschaftspädagogikstudierende schriftlich befragt. Die Ergebnisse zeigen, dass das anfängliche Berufsethos der Befragten bereits in der universitären Ausbildungsphase relativ stark ausgeprägt ist. Weiterhin ist zu erkennen, dass das Berufsethos bei angehenden Wirtschaftspädagog*innen, die den Berufswunsch Lehrkraft haben, ausgeprägter ist als bei Wirtschaftspädagogikstudierenden, die eine Tätigkeit außerhalb des Schuldienstes anstreben bzw. noch unentschlossen sind. Letztlich kann aufgezeigt werden, dass grundsätzlich positive Zusammenhänge zwischen dem anfänglich ausgeprägten Berufsethos und der Berufswahlmotivation von angehenden Wirtschaftspädagog*innen bestehen.","lang":"ger"}],"publication":"bwp@ Spezial","language":[{"iso":"ger"}],"main_file_link":[{"open_access":"1","url":"https://www.bwpat.de/spezial18/ziegler_goller_spezial18.pdf"}],"article_type":"original","intvolume":"        18","publication_status":"published","date_updated":"2022-01-06T06:55:15Z","publication_identifier":{"issn":["1618-8543"]},"author":[{"first_name":"Michael","orcid":"0000-0002-2820-9178","last_name":"Goller","full_name":"Goller, Michael","id":"30984"},{"first_name":"Simone","last_name":"Ziegler","full_name":"Ziegler, Simone"}],"title":"Zum Zusammenhang von Berufsethos und der Berufswahlmotivation angehender Wirtschaftspädagog*innen","year":"2021"},{"abstract":[{"lang":"eng","text":"<jats:p>The reduction of high-dimensional systems to effective models on a smaller set of variables is an essential task in many areas of science. For stochastic dynamics governed by diffusion processes, a general procedure to find effective equations is the conditioning approach. In this paper, we are interested in the spectrum of the generator of the resulting effective dynamics, and how it compares to the spectrum of the full generator. We prove a new relative error bound in terms of the eigenfunction approximation error for reversible systems. We also present numerical examples indicating that, if Kramers–Moyal (KM) type approximations are used to compute the spectrum of the reduced generator, it seems largely insensitive to the time window used for the KM estimators. We analyze the implications of these observations for systems driven by underdamped Langevin dynamics, and show how meaningful effective dynamics can be defined in this setting.</jats:p>"}],"publication":"Entropy","citation":{"mla":"Nüske, Feliks, et al. “Spectral Properties of Effective Dynamics from Conditional Expectations.” <i>Entropy</i>, 134, 2021, doi:<a href=\"https://doi.org/10.3390/e23020134\">10.3390/e23020134</a>.","bibtex":"@article{Nüske_Koltai_Boninsegna_Clementi_2021, title={Spectral Properties of Effective Dynamics from Conditional Expectations}, DOI={<a href=\"https://doi.org/10.3390/e23020134\">10.3390/e23020134</a>}, number={134}, journal={Entropy}, author={Nüske, Feliks and Koltai, Péter and Boninsegna, Lorenzo and Clementi, Cecilia}, year={2021} }","ama":"Nüske F, Koltai P, Boninsegna L, Clementi C.

This task can be understood as the inverse problem of multiobjective optimization, where the goal is to find the objective function vector of a given Pareto set. To this end, we present a method to construct the objective function vector of an unconstrained multiobjective optimization problem (MOP) such that the Pareto critical set contains a given set of data points with prescribed KKT multipliers. If such an MOP can not be found, then the method instead produces an MOP whose Pareto critical set is at least close to the data points. The key idea is to consider the objective function vector in the multiobjective KKT conditions as variable and then search for the objectives that minimize the Euclidean norm of the resulting system of equations. By expressing the objectives in a finite-dimensional basis, we transform this problem into a homogeneous, linear system of equations that can be solved efficiently. Potential applications of this approach include the identification of objectives (both from clean and noisy data) and the construction of surrogate models for expensive MOPs."}],"main_file_link":[{"url":"https://link.springer.com/content/pdf/10.1007/s10898-020-00983-z.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1007/s10898-020-00983-z","year":"2021","title":"Inverse multiobjective optimization: Inferring decision criteria from data","author":[{"id":"32643","first_name":"Bennet","last_name":"Gebken","full_name":"Gebken, Bennet"},{"orcid":"https://orcid.org/0000-0002-3389-793X","first_name":"Sebastian","last_name":"Peitz","full_name":"Peitz, Sebastian","id":"47427"}],"date_updated":"2022-01-06T06:52:48Z","intvolume":"        80"},{"article_number":"eabl3903","main_file_link":[{"open_access":"1","url":"https://www.science.org/doi/10.1126/sciadv.abl3903"}],"language":[{"iso":"eng"}],"doi":"10.1126/sciadv.abl3903","title":"Observing 0D subwavelength-localized modes at ~100 THz protected by weak topology","year":"2021","publication_identifier":{"issn":["2375-2548"]},"author":[{"last_name":"Lu","first_name":"Jinlong","full_name":"Lu, Jinlong"},{"full_name":"Wirth, Konstantin G.","last_name":"Wirth","first_name":"Konstantin G."},{"full_name":"Gao, Wenlong","last_name":"Gao","first_name":"Wenlong"},{"first_name":"Andreas","last_name":"Heßler","full_name":"Heßler, Andreas"},{"first_name":"Basudeb","last_name":"Sain","full_name":"Sain, Basudeb"},{"full_name":"Taubner, Thomas","last_name":"Taubner","first_name":"Thomas"},{"full_name":"Zentgraf, Thomas","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101","id":"30525"}],"publication_status":"published","date_updated":"2022-03-03T07:25:11Z","article_type":"original","intvolume":"         7","file":[{"date_created":"2022-03-03T07:24:44Z","creator":"zentgraf","file_id":"30197","content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2022-03-03T07:24:44Z","file_name":"2021_ScienceAdv_TopologicalMode_Manuscript_Arxiv.pdf","access_level":"closed","file_size":2609760}],"date_created":"2021-12-02T19:40:56Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"issue":"49","publication":"Science Advances","abstract":[{"lang":"eng","text":"Topological photonic crystals (TPhCs) provide robust manipulation of light with built-in immunity to fabrication tolerances and disorder. Recently, it was shown that TPhCs based on weak topology with a dislocation inherit this robustness and further host topologically protected lower-dimensional localized modes. However, TPhCs with weak topology at optical frequencies have not been demonstrated so far. Here, we use scattering-type scanning near-field optical microscopy to verify mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with nontrivial Zak phase and an edge dislocation. We show that because of the weak topology, differently extended dislocation centers induce similarly strong light localization. The experimental results are supported by full-field simulations. Along with the underlying fundamental physics, our results lay a foundation for the application of TPhCs based on weak topology in active topological nanophotonics, and nonlinear and quantum optic integrated devices because of their strong and robust light localization."}],"_id":"28255","user_id":"30525","ddc":["530"],"volume":7,"status":"public","has_accepted_license":"1","oa":"1","file_date_updated":"2022-03-03T07:24:44Z","citation":{"mla":"Lu, Jinlong, et al. “Observing 0D Subwavelength-Localized Modes at ~100 THz Protected by Weak Topology.” <i>Science Advances</i>, vol. 7, no. 49, eabl3903, 2021, doi:<a href=\"https://doi.org/10.1126/sciadv.abl3903\">10.1126/sciadv.abl3903</a>.","ama":"Lu J, Wirth KG, Gao W, et al.

It shows how to computelossless, persisted summaries for callgraph, points-to anddata-flow information, and it reports under which circumstances this function-level compositionalanalysis outperforms WPA.We implementedModAlyzeras an extension to LLVM and PhASAR, and applied it to 12 real-world C and C++ applications. At analysis time,ModAlyzermodularly and losslessly summarizesthe analysis effect of the library code those applications share, hence avoiding its repeated re-analysis.The experimental results show that the reuse of these summaries can save, on average, 72% ofanalysis time over WPA. Moreover, because it is lossless, the module-wise analysis fully retainsprecision and recall. Surprisingly, as our results show, it sometimes even yields precision superior toWPA.

The study is intended to highlight the importance of considering manufacturing processes and optical measurement methods in a numerical simulation when analyzing the damage behavior of metallic materials. To describe the damage behavior of the material in the process chain simulations, it is important to calibrate the parameters of damage model more accurately. These parameters are determined using experimental investigation of desired damage specimens. In this regard, a selected damage specimen manufactured by different cutting processes is first experimentally and then numerically investigated. It is shown that the manufacturing process and the optical measurement methods influence the stress state analyzed in the numerical simulation.","lang":"eng"}]},{"citation":{"ieee":"J. Kirchhoff, S.

Since uncertainties about future developments increase planning difficulty, flexibility potentials such as synergies between the electricity, gas, heat, and transport sector often remain unused. In this paper, we therefore present a novel module-based concept for a decision support system that helps distribution network planners to identify cross-sectoral synergies and to select optimal network assets such as transformers, cables, pipes, energy storage systems or energy conversion technology. The concept enables long-term transformation plans and supports distribution network planners in designing reliable, sustainable and cost-efficient distribution networks for future demands."}],"date_created":"2021-01-28T10:05:44Z","oa":"1","department":[{"_id":"534"},{"_id":"66"},{"_id":"277"}],"type":"conference","conference":{"end_date":"2021-03-11","start_date":"2021-03-08","name":"Pre-Conference 16.

It is defined in stark contrast to total citation impact, a measure predominantly used in research evaluation that assumes that all citations are equal. Understanding ideational impact is critical for evaluating research impact and understanding how scientific disciplines build a cumulative tradition. Research has only recently developed automated citation classification techniques to distinguish between different types of citations and generally does not emphasize the conceptual content of the citations and its ideational impact. To address this problem, we develop Deep Content-enriched Ideational Impact Classification (Deep-CENIC) as the first automated approach for ideational impact classification to support researchers' literature search practices. We evaluate Deep-CENIC on 1,256 papers citing 24 information systems review articles from the IT business value domain. We show that Deep-CENIC significantly outperforms state-of-the-art benchmark models. We contribute to information systems research by operationalizing the concept of ideational impact, designing a recommender system for academic papers based on deep learning techniques, and empirically exploring the ideational impact of the IT business value domain.\r\n","lang":"eng"}],"publication":"Decision Support Systems","issue":"January","type":"journal_article","keyword":["Ideational impact","citation classification","academic recommender systems","natural language processing","deep learning","cumulative tradition"],"department":[{"_id":"277"}],"file":[{"creator":"hsiemes","date_created":"2020-10-27T13:31:01Z","relation":"main_file","date_updated":"2020-10-27T13:31:01Z","file_name":"DECSUP-D-20-00312 - PREPUBLICATION.pdf","access_level":"open_access","file_size":440903,"file_id":"20213","content_type":"application/pdf"}],"date_created":"2020-10-27T13:28:21Z","date_updated":"2022-06-10T06:55:32Z","intvolume":"       140","year":"2021","title":"Classifying the Ideational Impact of Information Systems Review Articles: A Content-Enriched Deep Learning Approach","author":[{"last_name":"Prester","first_name":"Julian","full_name":"Prester, Julian"},{"first_name":"Gerit","last_name":"Wagner","full_name":"Wagner, Gerit"},{"id":"72850","full_name":"Schryen, Guido","first_name":"Guido","last_name":"Schryen"},{"last_name":"Hassan","first_name":"Nik Rushdi","full_name":"Hassan, Nik Rushdi"}],"article_number":"113432","language":[{"iso":"eng"}]},{"has_accepted_license":"1","status":"public","volume":58,"user_id":"72850","ddc":["000"],"_id":"20844","citation":{"mla":"Wagner, Gerit, et al. “Which Factors Affect the Scientific Impact of Review Papers in IS Research?

Insbesondere wenn das zugrunde liegende System von einem Parameter abhängt, ist es entscheidend, sie im Bezug auf diesen Parameter effizient zu verfolgen. Für die Berechnung invarianter Mengen stützen wir uns für ihre Approximation auf numerische Algorithmen. Typischerweise können diese Methoden jedoch nur auf endlich-dimensionale dynamische Systeme angewendet werden. In dieser Arbeit präsentieren wir daher einen numerischen Rahmen für die globale dynamische Analyse unendlich-dimensionaler Systeme. Wir werden Einbettungstechniken verwenden, um das core dynamical system (CDS) zu definieren, welches ein dynamisch äquivalentes endlich-dimensionales System ist.Das CDS wird dann verwendet, um eingebettete invariante Mengen, also eins-zu-eins Bilder, mittels Mengen-orientierten numerischen Methoden zu approximieren. Bei der Konstruktion des CDS ist es entscheidend, eine geeignete Beobachtungsabbildung auszuwählen und die geeignete inverse Abbildung zu entwerfen. Dazu werden wir geeignete numerische Implementierungen des CDS für DDEs und PDEs vorstellen. Für eine nachfolgende geometrische Analyse der eingebetteten invarianten Menge betrachten wir eine Lerntechnik namens diffusion maps, die ihre intrinsische Geometrie enthüllt sowie ihre Dimension schätzt. Schließlich wenden wir unsere entwickelten numerischen Methoden an einigen bekannten unendlich-dimensionale dynamischen Systeme an, wie die Mackey-Glass-Gleichung, die Kuramoto-Sivashinsky-Gleichung und die Navier-Stokes-Gleichung."},{"text":"One central aspect in the study of dynamical systems is the analysis of its invariant sets such as the global attractor and (un)stable manifolds. In particular, when the underlying system depends on a parameter it is crucial to efficiently track those set with respect to this parameter. For the computation of invariant sets we rely on numerical algorithms for their approximation but typically those tools can only be applied to finite-dimensional dynamical systems. Thus, in thesis we present a numerical framework for the global dynamical analysis of infinite-dimensional systems. We will use embedding techniques for the definition of the core dynamical system (CDS) which is a dynamically equivalent finite-dimensional system. The CDS is then used for the approximation of related embedded invariant sets, i.e, one-to-one images, by set-oriented numerical methods. For the construction of the CDS it is crucial to choose an appropriate observation map and to design its corresponding inverse. Therefore, we will present suitable numerical realizations of the CDS for DDEs and PDEs. For a subsequent geometric analysis of the embedded invariant set we will consider a manifold learning technique called diffusion maps which reveals its intrinsic geometry and estimates its dimension. Finally, we apply our develop numerical tools on some well-known infinite-dimensional dynamical systems such as the Mackey-Glass equation, the Kuramoto-Sivashinsky equation and the Navier-Stokes equation.","lang":"eng"}],"supervisor":[{"full_name":"Dellnitz , Michael","first_name":"Michael","last_name":"Dellnitz "},{"last_name":"Koltai","first_name":"Péter","full_name":"Koltai, Péter"}],"citation":{"ieee":"R.
