Within the paradigm of model‐based design, the practicality and safety of commissioning feedforward controls and feedback controllers have priority. Our approach leverages probabilistic Gaussian processes to adjust for model inaccuracies from measured system data. This differs from conventional approaches that involve complicated analytical modeling and may entail a substantial time investment to acquire expertise and may prove impractical. Consequently, we address the limitations inherent in traditional design methodologies. Our research focuses on the formulation and solution of the hybrid1 optimal control problem using probabilistic state predictions and multiple shooting. This ensures adaptability, data efficiency, and resilience against uncertainties in system dynamics. These attributes are empirically substantiated through experimental validation on a chaotic and highly sensitive dynamical system—a double pendulum on a cart. Our methodology unfolds as an iterative learning process, systematically exploring diverse controls, accumulating data within each iteration, and refining the control strategy until the desired task is accomplished. The adoption of the two‐degree‐of‐freedom control structure allows for the distinct consideration of the feedforward and the feedback control signal. For the latter, we employ a time‐variant, linear quadratic regulator (LQR) designed to stabilize the system around its target trajectory. Furthermore, we integrate a probabilistic long‐term prediction through the unscented transform, enabling systematic anticipation of safety‐critical violations. Detailed insights into relevant implementation aspects are provided. To ascertain the real‐world applicability, we present an exemplary application involving a double pendulum on a cart. The objective is to bring the pendulum arms from the lower stable to the upper unstable equilibrium by horizontally moving the cart and subsequently stabilize them. In this scenario, we assume that the centrifugal forces, crucial to the system dynamics, have not been accurately modeled and must be learned from data. Solving the control task took only 5 iterations and 1 h of computation time, which surpasses our previous work [2], where we used the purely data‐driven PILCO framework and required 27 iterations and 57 h of computation time. The time of interaction with the system decreased by and the computation time is lowered by . It demonstrates significant practical applicability for commissioning control systems.}}, author = {{Hesse, Michael and Schwarzer, Luis and Timmermann, Julia and Trächtler, Ansgar}}, issn = {{1617-7061}}, journal = {{PAMM}}, number = {{2}}, publisher = {{Wiley}}, title = {{{Robust and Efficient Hybrid Optimal Control via Gaussian Process Regression and Multiple Shooting With Experimental Validation on a Double Pendulum on a Cart}}}, doi = {{10.1002/pamm.70004}}, volume = {{25}}, year = {{2025}}, } @article{61117, author = {{Ratzke, Christian and Candan, Ayse Beyza}}, journal = {{Zeitschrift für christlich-jüdische Begegnung}}, number = {{1}}, title = {{{Reflexion religionsbezogener Einstellungen im Kontext interreligiöser Bildung anlässlich 80 Jahre nach Auschwitz}}}, volume = {{1}}, year = {{2025}}, } @misc{61122, author = {{Peckhaus, Volker}}, booktitle = {{zbMATH Open, Zbl. 07963874}}, title = {{{Bolzano, Bernard, Miscellanea mathematica 22, hg. v.

However, recent years have shown almost exponential growth in attackers leveraging these software artifacts to launch software supply chain attacks. Past well-known software supply chain attacks include the SolarWinds, log4j, and xz utils incidents. Supply chain attacks are considered to have three major attack vectors: through vulnerabilities and malware accidentally or intentionally injected into open source and third-party dependencies/components/containers ; by infiltrating the build infrastructure during the build and deployment processes; and through targeted techniques aimed at the humans involved in software development, such as through social engineering. Plummeting trust in the software supply chain could decelerate digital innovation if the software industry reduces its use of open source and third-party artifacts to reduce risks. This article contains perspectives and knowledge obtained from intentional outreach with practitioners to understand their practical challenges and from extensive research efforts. We then provide an overview of current research efforts to secure the software supply chain. Finally, we propose a future research agenda to close software supply chain attack vectors and support the software industry. }}, author = {{Williams, Laurie and Benedetti, Giacomo and Hamer, Sivana and Paramitha, Ranindya and Rahman, Imranur and Tamanna, Mahzabin and Tystahl, Greg and Zahan, Nusrat and Morrison, Patrick and Acar, Yasemin and Cukier, Michel and Kästner, Christian and Kapravelos, Alexandros and Wermke, Dominik and Enck, William}}, issn = {{1049-331X}}, journal = {{ACM Transactions on Software Engineering and Methodology}}, number = {{5}}, pages = {{1--38}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Research Directions in Software Supply Chain Security}}}, doi = {{10.1145/3714464}}, volume = {{34}}, year = {{2025}}, } @inbook{61127, author = {{Haney, Julie M. and Acar, Yasemin and Li, Anna and Haney, Faith}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{9783031928390}}, issn = {{0302-9743}}, publisher = {{Springer Nature Switzerland}}, title = {{{Smart Home Users’ Security and Privacy Perceptions and Actions Differ By Device Category: Results from a U.S. Survey}}}, doi = {{10.1007/978-3-031-92840-6_11}}, year = {{2025}}, } @inproceedings{61129, author = {{Rotthaler, Anna Lena and Ramulu, Harshini Sri and Simko, Lucy and Fahl, Sascha and Acar, Yasemin}}, booktitle = {{IEEE Symposium on Security and Privacy, SP 2025, San Francisco, CA, USA, May 12-15, 2025}}, editor = {{Blanton, Marina and Enck, William and Nita-Rotaru, Cristina}}, pages = {{2228–2245}}, publisher = {{IEEE}}, title = {{{"It’s Time.

In humans, these periods may partly explain the higher prevalence of osteoporosis in older women compared with men, but lactation patterns in modern humans may reflect cultural influences rather than natural conditions. The extent to which these findings apply to wild-living mammals remains unknown. We measured urinary C-terminal crosslinking telopeptide of Type I collagen (CTX-I) levels, a bone resorption marker, during pregnancy in wild and zoo-housed bonobos (Pan paniscus) and during lactation in wild bonobos. Studying wild-living primates such as bonobos can provide insights into ancestral reproductive adaptations. We found an increase in CTX-I levels towards the end of pregnancy in zoo-housed and primiparous wild females. Contrary to expectations, CTX-I levels during early lactation are lower than in other reproductive phases. This pattern diverges from the assumption that lactation increases bone resorption. Our findings suggest that wild bonobos may use physiological or behavioral strategies to modulate bone metabolism during lactation. These adaptations, shaped in natural environments, provide insight into evolutionary pressures on skeletal health and may inform strategies to mitigate bone loss in humans.}}, author = {{Behringer, Verena and Sonnweber, Ruth and Fruth, Barbara and Housman, Genevieve and Douglas, Pamela Heidi and Stevens, Jeroen M.
