In order to tune the properties, different functionalities need to be incorporated into the oligomers and the chain tacticity needs to be controlled. Beside the synthesis of SDOs, suitable methods need to be found to analyze the molecular structure. In this work, oligomers exhibiting an alternating or block-wise sequence of side chain functionalities were analyzed using a hyphenation of ultra-high-performance liquid chromatography and electrospray ionization mass spectrometry enhanced by ion mobility separation (IMS). Moieties in the side chains were varied according to polarity and bulkiness. Moreover, chain tacticity was varied. Drift times in the IMS cell and the corresponding collision cross section (CCS) values were shown to be individual parameters allowing the identification of SDOs, even in the case that SDO structures only differ in sequence or tacticity of side chain functionalities. Thus, a library of CCS values was obtained as reference used for the analysis of complex mixtures of SDOs.","lang":"eng"}],"publication":"International Journal of Polymer Analysis and Characterization","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Ultra-high-performance liquid chromatography","ion mobility separation","mass spectrometry","LC-MS hyphenation","sequence-defined oligomers"],"article_type":"original","department":[{"_id":"163"}],"user_id":"94","_id":"32416"},{"title":"Die Wirksamkeit von Lernzielen für Studienleistungen – eine experimentelle Studie","date_created":"2023-05-05T17:19:24Z","year":"2022","quality_controlled":"1","issue":"1","keyword":["learning objectives","academic performance","perception","teaching methods","experiment"],"language":[{"iso":"ger"}],"abstract":[{"lang":"eng","text":"According to the German Rectors’ Conference (HRK), German higher education teaching fails to\r\nmeet the demand to integrate competence-oriented learning objectives. Despite a wide-ranging debate on the use of learning objectives, empirical research on their effectiveness is scarce. The present study uses the features of digital teaching platforms to investigate the perception and effectiveness of learning objectives applying a randomised controlled experiment followed by a survey in a course for undergraduate economics students (N = 30). Controlling group preconditions and the treatment effect allows to draw conclusions about the different learning outcomes of the student groups. The specification of behaviour-oriented learning objectives in the online course system leads to significantly better performance in the treatment group. A stronger perception of the learning objectives in the treatment group supports this effect that remains significant in a regression analysis.

We illustrate why commonly used diversity measures are not entirely appropriate for this task and propose a sophisticated basin-based evaluation (BBE) method. Also, BBE variants are developed, capturing the anytime behavior of algorithms. The set of BBE measures is tested by means of an algorithm configuration study. We show that these new measures also transfer properties of the well-established hypervolume (HV) indicator to the domain of MMMOO, thus also accounting for objective space convergence. Moreover, we advance MMMOO research by providing insights into the multimodal performance of the considered algorithms. Specifically, algorithms exploiting local structures are shown to outperform classical evolutionary multi-objective optimizers regarding the BBE variants and respective trade-off with HV.","lang":"eng"}],"keyword":["Anytime behavior","Benchmarking","Continuous optimization","Multi-objective optimization","Multimodality","Performance metric"],"language":[{"iso":"eng"}],"year":"2022","publisher":"Springer International Publishing","date_created":"2023-11-14T15:58:58Z","title":"BBE: Basin-Based Evaluation of Multimodal Multi-objective Optimization Problems"},{"year":"2022","title":"Performance Management Approach for Digital Platforms in B2B Markets","date_created":"2022-11-04T07:31:57Z","abstract":[{"lang":"eng","text":"Digital platforms have already led to disruptions in multiple B2C markets and are becoming increasingly dominant in B2B markets.

Since many scheduling problems are NP-hard in the strong sense, there is only limited research on exact algorithms and how their efficiency scales when implemented on parallel computing architectures. We address this gap by (1) adapting an exact branch-and-price algorithm to a parallel machine scheduling problem on unrelated machines with sequence- and machine-dependent setup times, (2) parallelizing the adapted algorithm by implementing a distributed-memory parallelization with a master/worker approach, and (3) conducting extensive computational experiments using up to 960 MPI processes on a modern high performance computing cluster. With our experiments, we show that the efficiency of our parallelization approach can lead to superlinear speedup but can vary substantially between instances. We further show that the wall time of serial execution can be substantially reduced through our parallelization, in some cases from 94 hours to less than six minutes when our algorithm is executed on 960 processes.","lang":"eng"}],"publication":"Computers & Operations Research","type":"journal_article"},{"date_updated":"2022-05-04T06:15:02Z","date_created":"2018-10-01T12:17:35Z","author":[{"id":"48476","full_name":"Hippert, Benjamin","last_name":"Hippert","first_name":"Benjamin"},{"first_name":"André","id":"36049","full_name":"Uhde, André","last_name":"Uhde","orcid":"https://orcid.org/0000-0002-8058-8857"},{"first_name":"Sascha Tobias","last_name":"Wengerek","orcid":"0000-0002-7820-3903","id":"48837","full_name":"Wengerek, Sascha Tobias"}],"volume":22,"title":"Portfolio Benefits of Adding Corporate Credit Default Swap Indices: Evidence from North America and Europe","doi":"https://doi.org/10.1007/s11147-018-9148-8","publication_status":"published","issue":"2","year":"2019","citation":{"short":"B.

As a baseline result, we initially find an increase in portfolio (downside) risk-diversification when adding CDS indices, which is observed irrespective of both CDS markets, investor-types and different sub-periods, including the global financial crisis and European sovereign debt crisis. In addition, the analysis reveals higher portfolio excess returns and performance in CDS index portfolios, however, these effects clearly differ between markets, investor-types and sub-periods. Overall, portfolio benefits of adding CDS indices mainly result from the fact that institutional investors replace sovereign bond indices rather than stock indices by CDS indices due to better risk-return characteristics. Our baseline findings remain robust under a variety of robustness checks. Results from sensitivity analyses provide further important implications for institutional investors with a strategic focus on a long-term conservative portfolio management."}],"status":"public"},{"year":"2019","publisher":"Springer International Publishing","date_created":"2023-11-14T15:58:57Z","title":"Multi-Objective Performance Measurement: Alternatives to PAR10 and Expected Running Time","publication":"Learning and Intelligent Optimization","abstract":[{"text":"A multiobjective perspective onto common performance measures such as the PAR10 score or the expected runtime of single-objective stochastic solvers is presented by directly investigating the tradeoff between the fraction of failed runs and the average runtime.

This is robust to measures of performance persistence, time period effects, and other contract terms and is related to exit-timing incentives.

Over the years, many different solution approaches and solvers have been developed. For the first time, we directly compare five state-of-the-art inexact solvers\\textemdash namely, LKH, EAX, restart variants of those, and MAOS\\textemdash on a large set of well-known benchmark instances and demonstrate complementary performance, in that different instances may be solved most effectively by different algorithms. We leverage this complementarity to build an algorithm selector, which selects the best TSP solver on a per-instance basis and thus achieves significantly improved performance compared to the single best solver, representing an advance in the state of the art in solving the Euclidean TSP. Our in-depth analysis of the selectors provides insight into what drives this performance improvement."}],"type":"journal_article","publication":"Evolutionary Computation","language":[{"iso":"eng"}],"keyword":["automated algorithm selection","machine learning.","performance modeling","Travelling Salesperson Problem"],"user_id":"102979","department":[{"_id":"819"}],"_id":"48884"},{"_id":"5185","user_id":"64756","department":[{"_id":"275"}],"keyword":["venture capital","compensation","private equity","VC partnership","pay-performance relation"],"language":[{"iso":"eng"}],"type":"journal_article","publication":"SSRN Electronic Journal","abstract":[{"lang":"eng","text":"We offer the first empirical analysis connecting the timing of general partner (GP) compensation to private equity fund performance.

This is robust to measures of performance persistence, time period effects, and other contract terms, and is related to exit-timing incentives.

Since many scheduling problems are NP-hard in the strong sense, there is a need for developing solution heuristics. For scheduling problems with setup times on unrelated parallel machines, there is limited research on solution methods and to the best of our knowledge, parallel computer architectures have not yet been taken advantage of. We address this gap by proposing and implementing a new solution heuristic and by testing different parallelization strategies. In our computational experiments, we show that our heuristic calculates near-optimal solutions even for large instances and that computing time can be reduced substantially by our parallelization approach."}],"type":"conference","publication":"Australasian Conference on Information Systems","language":[{"iso":"eng"}],"extern":"1","file_date_updated":"2018-12-13T15:08:28Z","ddc":["000"],"keyword":["scheduling","decision support","heuristic","high performance computing","parallel algorithms"],"user_id":"61579","department":[{"_id":"277"}],"_id":"5678"},{"type":"journal_article","status":"public","department":[{"_id":"181"}],"user_id":"37741","_id":"5705","article_type":"original","publication_status":"published","intvolume":"        26","page":"127-139","citation":{"bibtex":"@article{Breugelmans_Bijmolt_Zhang_Basso_Dorotic_Kopalle_Minnema_Mijnlieff_Wünderlich_2015, title={Advancing Research on Loyalty Programs: A Future Research Agenda.}, volume={26}, number={2}, journal={Marketing Letters}, publisher={Springer}, author={Breugelmans, Els and Bijmolt, Tammo H A and Zhang, Jie and Basso, Leonardo J and Dorotic, Matilda and Kopalle, Praveen and Minnema, Alec and Mijnlieff, Willem Jan and Wünderlich, Nancy}, year={2015}, pages={127–139} }","short":"E.
