Unter Einbezug von Erkenntnissen aus der Verhaltensökonomie und der Mensch-Maschine-Interaktion wird analysiert, wie kognitive Limitationen, soziale Präferenzen und Wahrnehmungsverzerrungen das Verhalten in Kontexten von Unehrlichkeit, Empfehlungsumsetzung, Feedbackverarbeitung und Selbsteinschätzung prägen. Vier kontrollierte ökonomische Experimente zeigen, dass algorithmische Intransparenz unehrliches Verhalten verstärken kann, die Einbindung von Nutzern in das Training von KI-Systemen zwar deren Wahrnehmung verbessert, jedoch nicht die tatsächliche Befolgung algorithmischer Ratschläge fördert, dass Echtzeit-Feedback in Human-in-the-Loop-Systemen unbeabsichtigt Verhaltensverzerrungen verstärken kann und dass gängige Messungen von Selbstüberschätzung stark von methodischen Designentscheidungen abhängen. Die Dissertation unterstreicht die Notwendigkeit, realistische Annahmen über menschliches Verhalten bei der Gestaltung von Prüfungsprozessen, Empfehlungssystemen und interaktiven Technologien zu berücksichtigen und leistet damit einen Beitrag zu einem besseren Verständnis menschlicher Entscheidungsprozesse in einer zunehmend automatisierten Welt."},{"text":"This dissertation investigates how humans make decisions in interactions with both other people and increasingly prevalent algorithmic systems. Integrating insights from behavioral economics and human-machine interaction, it examines how cognitive limitations, social preferences, and perceptual biases shape behavior in contexts involving dishonesty, advice-taking, feedback, and self-assessment. Across four controlled economic experiments, the studies show that algorithmic opacity can increase dishonest behavior, user involvement in AI training improves perceptions but not actual adherence to algorithmic advice, real-time feedback in human-in-the-loop systems can unintentionally amplify behavioral biases, and common measures of overconfidence are sensitive to methodological design. The dissertation underscores the need to incorporate realistic behavioral assumptions when designing verification processes, advisory algorithms, and interactive technologies, contributing to a deeper understanding of human decision-making in an increasingly automated world.","lang":"eng"}],"citation":{"mla":"Protte, Marius.

Predefined phases are selected without restrictions in the order according to a multi-objective optimisation to adapt to the traffic as freely as possible. Initially, the system is tested in simulations and compared with existing methods and analysed afterwards for its effectiveness in a prototype commissioning in field tests. Results indicate high potentials for reducing emissions and waiting times, highlighting the system's value. However, further refinement is necessary for standard implementation. This comprehensive approach demonstrates advancements in traffic management technology, showcasing the potential for enhancing urban mobility and reducing environmental impact.","lang":"eng"}],"related_material":{"link":[{"relation":"confirmation","url":"https://ieeexplore.ieee.org/document/10919569"}]},"publication":"2024 IEEE 27th International Conference on Intelligent Transportation Systems (ITSC)"},{"citation":{"chicago":"Rossmann, Felix. “Zum Verhältnis von Nachhaltigkeitsbezogener Transparenz Und Strategischem Sichtbarkeitsmanagement.” In Jahrbuch Normative Und Institutionelle Grundfragen Der Ökonomik, edited by Richard Sturn and Ulrich Klüh, 22nd ed., 15 pp. Schattenwirtschaft – Schattenpolitik.

Software following this paradigm is often referred to as “constant-time” software and typically involves following three rules: 1) never branch on a secret-dependent condition, 2) never access memory at a secret-dependent location, and 3) avoid variable-time arithmetic operations on secret data. The third rule requires knowledge about such variable-time arithmetic instructions, or vice versa, which operations are safe to use on secret inputs. For a long time, this knowledge was based on either documentation or microbenchmarks, but critically, there were never any guarantees for future microarchitectures. This changed with the introduction of the data-operand-independent-timing (DOIT) mode on Intel CPUs and, to some extent, the data-independent-timing (DIT) mode on Arm CPUs. Both Intel and Arm document a subset of their respective instruction sets that are intended to leak no information about their inputs through timing, even on future microarchitectures if the CPU is set to run in a dedicated DOIT (or DIT) mode.In this paper, we present a principled solution that leverages DOIT to enable cryptographic software that is future-proof constant-time, in the sense that it ensures that only instructions from the DOIT subset are used to operate on secret data, even during speculative execution after a mispredicted branch or function return location. For this solution, we build on top of existing security type systems in the Jasmin framework for high-assurance cryptography.We then use our solution to evaluate the extent to which existing cryptographic software built to be “constant-time” is already secure in this stricter paradigm implied by DOIT and what the performance impact is to move from constant-time to future-proof constant-time."}],"_id":"65537","publisher":"Universitatsbibliothek der Ruhr-Universitat Bochum","page":"644-667","volume":2025,"doi":"10.46586/tches.v2025.i3.644-667","user_id":"125442","author":[{"last_name":"Arranz-Olmos","first_name":"Santiago","full_name":"Arranz-Olmos, Santiago"},{"full_name":"Barthe, Gilles","last_name":"Barthe","first_name":"Gilles"},{"full_name":"Grégoire, Benjamin","first_name":"Benjamin","last_name":"Grégoire"},{"full_name":"Jancar, Jan","first_name":"Jan","last_name":"Jancar"},{"full_name":"Laporte, Vincent","last_name":"Laporte","first_name":"Vincent"},{"first_name":"Tiago","last_name":"Oliveira","full_name":"Oliveira, Tiago"},{"last_name":"Schwabe","first_name":"Peter","full_name":"Schwabe, Peter"}],"publication_identifier":{"issn":["2569-2925"]},"title":"Let’s DOIT: Using Intel’s Extended HW/SW Contract for Secure Compilation of Crypto Code","year":"2025","status":"public","intvolume":" 2025","date_updated":"2026-04-30T09:32:27Z","publication_status":"published"},{"citation":{"ieee":"V.

The literature on elliptic curves offers a plethora of curve models, scalar multipliers, and addition formulas, but this comes with the price of enabling attacks to also use the rich structure of these techniques. Navigating through this area is not an easy task and developers often obscure their choices, especially in black-box hardware implementations. Since side-channel attackers rely on the knowledge of the implementation details, reverse engineering becomes a crucial part of attacks.This work presents ECTester – a tool for testing black-box ECC implementations. Through various test suites, ECTester observes the behavior of the target implementation against known attacks but also non-standard inputs and elliptic curve parameters. We analyze popular ECC libraries and smartcards and show that some libraries and most smartcards do not check the order of the input points and improperly handle the infinity point. Based on these observations, we design new techniques for reverse engineering scalar randomization countermeasures that are able to distinguish between group scalar randomization, additive, multiplicative or Euclidean splitting. Our techniques do not require side-channel measurements; they only require the ability to set custom domain parameters, and are able to extract not only the size but also the exact value of the random mask used. Using the techniques, we successfully reverse-engineered the countermeasures on 13 cryptographic smartcards from 5 major manufacturers – all but one we tested on. Finally, we discuss what mitigations can be applied to prevent such reverse engineering, and whether it is possible at all.","lang":"eng"}],"date_created":"2026-04-30T09:31:59Z","type":"journal_article","publication_identifier":{"issn":["2569-2925"]},"author":[{"last_name":"Suchanek","first_name":"Vojtech","full_name":"Suchanek, Vojtech"},{"full_name":"Jancar, Jan","last_name":"Jancar","first_name":"Jan"},{"last_name":"Kvapil","first_name":"Jan","full_name":"Kvapil, Jan"},{"first_name":"Petr","last_name":"Svenda","full_name":"Svenda, Petr"},{"last_name":"Chmielewski","first_name":"Łukasz","full_name":"Chmielewski, Łukasz"}],"title":"ECTester: Reverse-engineering side-channel countermeasures of ECC implementations","year":"2025","status":"public","intvolume":" 2025","publication_status":"published","date_updated":"2026-04-30T09:32:25Z","publisher":"Universitatsbibliothek der Ruhr-Universitat Bochum","_id":"65538","page":"290-316","volume":2025,"user_id":"125442","doi":"10.46586/tches.v2025.i4.290-316"},{"citation":{"mla":"Gharibian, Sevag, and Jonas Kamminga. “On the Complexity of Estimating Ground State Entanglement and Free  Energy.” ArXiv:2510.06796, 2025.","bibtex":"@article{Gharibian_Kamminga_2025, title={On the complexity of estimating ground state entanglement and free  energy}, journal={arXiv:2510.06796}, author={Gharibian, Sevag and Kamminga, Jonas}, year={2025} }","ama":"Gharibian S, Kamminga J.

More concretely, the study illustrates how early-career researchers experience and express their agency in research writing through personal metaphors of academic writing such as riding a roller coaster or baking a wedding cake. A two-step discursive analysis adapts Hopper and Thompson's multidimensional approach to linguistic transitivity to study agency in language. The analytical approach involves both an in-depth parametrized analysis of all metaphors in the sample and a qualitative cross-analysis of the data. The results show that the participants' metaphors reflect both nuanced personal experiences and cultural expectations of academic writing, the writer, and the text. This emphasizes that research writing is not only a highly subjective practice but also one that is socially and culturally influenced. The article argues that research on agency thus needs elaborate methodological tools to trace discursive and sociopsychological trajectories of complex socio-cognitive practices like academic writing. This has implications not only for the nexus of research writing, identity, and academic enculturation but also for other fields focusing on agency in language."}],"publication":"Frontiers in Language Sciences","citation":{"mla":"Karsten, Andrea. “Understanding Personal Agency through Metaphor, or Why Academic Writing Is (Not) like a Roller-Coaster Ride.” Frontiers in Language Sciences, vol. 4, 1567498, Frontiers Media SA, 2025, doi:10.3389/flang.2025.1567498.","bibtex":"@article{Karsten_2025, title={Understanding personal agency through metaphor, or Why academic writing is (not) like a roller-coaster ride}, volume={4}, DOI={10.3389/flang.2025.1567498}, number={1567498}, journal={Frontiers in Language Sciences}, publisher={Frontiers Media SA}, author={Karsten, Andrea}, year={2025} }","ama":"Karsten A.

More concretely, the study illustrates how early-career researchers experience and express their agency in research writing through personal metaphors of academic writing such as riding a roller coaster or baking a wedding cake. A two-step discursive analysis adapts Hopper and Thompson's multidimensional approach to linguistic transitivity to study agency in language. The analytical approach involves both an in-depth parametrized analysis of all metaphors in the sample and a qualitative cross-analysis of the data. The results show that the participants' metaphors reflect both nuanced personal experiences and cultural expectations of academic writing, the writer, and the text. This emphasizes that research writing is not only a highly subjective practice but also one that is socially and culturally influenced. The article argues that research on agency thus needs elaborate methodological tools to trace discursive and sociopsychological trajectories of complex socio-cognitive practices like academic writing. This has implications not only for the nexus of research writing, identity, and academic enculturation but also for other fields focusing on agency in language.","lang":"eng"}],"publication":"Frontiers in Language Sciences","type":"journal_article","date_created":"2025-09-10T10:51:29Z","publication_status":"published","date_updated":"2026-05-06T08:42:08Z","intvolume":" 4","year":"2025","title":"Understanding personal agency through metaphor, or Why academic writing is (not) like a roller-coaster ride","author":[{"last_name":"Karsten","orcid":"0000-0003-0194-2000","first_name":"Andrea Ramona","full_name":"Karsten, Andrea Ramona","id":"53917"}],"publication_identifier":{"issn":["2813-4605"]},"doi":"10.3389/flang.2025.1567498","article_number":"1567498","language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"The use of continuous fiber-reinforced thermoplastics (FRTP) in automotive industry increases due to their excellent material properties and possibility of rapid processing. The scale spanning heterogeneity of their material structure and its influence on the material behavior, however, presents significant challenges for most joining technologies, such as self-piercing riveting (SPR). During mechanical joining, the material structure is significantly altered within and around the joining zone, heavily influencing the material behavior. A comprehensive understanding of the underlying phenomena of material alteration during the SPR process is essential as basis for validating numerical simulations. This study examines the material structure at ten stages of a step-setting test of SPR with two FRTP sheets with glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage phenomena within different areas of the setting test are analyzed three-dimensionally and key parameters are quantified. Dominating phenomena during the penetration of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF) and fiber bending, while delamination, fiber kinking and roving splitting are also observed. At the final stages, the bottom layers of the second sheet collapse and form a bulge into the cavity of the die."}],"publication":"Proceedings of the 8th International Conference on Integrity-Reliability-Failure (IRF2025)","keyword":["self-piercing riveting","computed tomography","thermoplastic composites","process-structure-interaction"],"type":"conference","date_created":"2025-09-08T11:52:45Z","publication_status":"published","date_updated":"2026-05-07T08:40:51Z","publication_identifier":{"isbn":["9789727523238"]},"author":[{"full_name":"Dargel, Alrik","first_name":"Alrik","last_name":"Dargel","id":"114764"},{"full_name":"Gröger, Benjamin","first_name":"Benjamin","last_name":"Gröger"},{"full_name":"Schlichter, Malte Christian","first_name":"Malte Christian","last_name":"Schlichter","id":"61977"},{"id":"105344","last_name":"Gerritzen","first_name":"Johannes","orcid":"0000-0002-0169-8602","full_name":"Gerritzen, Johannes"},{"first_name":"Daniel","last_name":"Köhler","full_name":"Köhler, Daniel","id":"83408"},{"id":"32056","first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","full_name":"Meschut, Gerson"},{"last_name":"Gude","first_name":"Maik","full_name":"Gude, Maik"},{"full_name":"Kupfer, Robert","first_name":"Robert","last_name":"Kupfer"}],"title":"Local Deformation and Failure of Composites during Self-Piercing Riveting: A CT-Based Microstructure Investigation","year":"2025","doi":"10.24840/978-972-752-323-8","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.researchgate.net/publication/395593556_LOCAL_DEFORMATION_AND_FAILURE_OF_COMPOSITES_DURING_SELF-PIERCING_RIVETING_A_CT_BASED_MICROSTRUCTURE_INVESTIGATION","open_access":"1"}],"project":[{"_id":"133","name":"TRR 285 - Project Area C"},{"_id":"148","name":"TRR 285 - Subproject C04"},{"name":"TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"_id":"131","name":"TRR 285 - Project Area A"},{"name":"TRR 285 - Subproject A03","_id":"137"},{"name":"TRR 285 - Subproject A01","_id":"135"}],"citation":{"ieee":"A.
