We illustrate the proposed method by an example of photon pairs generated in a periodically poled potassium titanyl phosphate (KTP) crystal with a symmetric group velocity matching for various durations of the pump pulse, resulting in different numbers of modes.

The process of joining is used in numerous sectors of the manufacturing industry, where constructions composed of individual components or metal sheets are combined to form complex structures. A straightforward and pervasive approach for joining materials of disparate natures and coated surfaces is clinching. During the clinching process, plastic deformation, residual stresses and damage are introduced into the joint. Due to time-varying service loads cracks can initiate and propagate in the vicinity of the joint which limits the lifetime of the clinched structure. In order to prevent those damage cases, it is crucial to perform fracture mechanical evaluation of cracks in the joint region. Therefore, this publication deals with the question of how plastic deformation, residual stresses and damage need to be considered for the assessment of a crack. For this purpose, simple substitute models are employed to illustrate the principles based on the clinching application example.}}, author = {{Weiß, Deborah and Duffe, Tobias and Joy, Tintu David and Kullmer, Gunter}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Consideration of residual stresses and damage in the fracture mechanical investigation of mechanically joined structures}}}, doi = {{10.21741/9781644903551-28}}, volume = {{52}}, year = {{2025}}, } @article{63909, abstract = {{IntroductionHuman-machine interactions become increasingly pervasive in daily life and professional contexts, motivating research to examine how human behavior changes when individuals interact with machines rather than other humans. While most of the existing literature focused on human-machine interactions with algorithmic systems in advisory roles, research on human behavior in monitoring or verification processes that are conducted by automated systems remains largely absent. This is surprising given the growing implementation of algorithmic systems in institutions, particularly in tax enforcement and financial regulation, to help monitor and identify misreports, or in online labor platforms widely implementing algorithmic control to ensure that workers deliver high service quality. Our study examines how human dishonesty changes when verification of statements that may be untrue is performed by machines vs. humans, and how ambiguity in the verification process influences dishonest behavior.MethodWe design an incentivized laboratory experiment using a modified die-roll paradigm where participants privately observe a random draw and report the result, with higher reported numbers yielding greater monetary rewards. A probabilistic verification process introduces risk of identifying a lie and punishment, with treatments varying by verification entity (human vs. machine) and degree of ambiguity in the verification process (transparent vs. ambiguous).ResultsOur results show that under transparent verification rules, cheating magnitude does not significantly differ between human and machine auditors. However, under ambiguous conditions, cheating magnitude is significantly higher when machines verify participants' reports, reducing the prevalence of partial cheating while leading to behavioral polarization manifested as either complete honesty or maximal overreporting. The same applies when comparing reports to a machine entity under ambiguous and transparent verification rules.DiscussionThese findings emphasize the behavioral implications of algorithmic opacity in verification contexts. While machines can serve as effective auditors under transparent conditions, their black box nature combined with ambiguous verification processes may unintentionally incentivize more severe dishonesty. These insights have practical implications for designing automated oversight systems in tax audits, compliance, and workplace monitoring.}}, author = {{Protte, Marius and Mir Djawadi, Behnud}}, issn = {{2813-5296}}, journal = {{Frontiers in Behavioral Economics}}, publisher = {{Frontiers Media SA}}, title = {{{Human vs. algorithmic auditors: the impact of entity type and ambiguity on human dishonesty}}}, doi = {{10.3389/frbhe.2025.1645749}}, volume = {{4}}, year = {{2025}}, } @article{63908, author = {{Mir Djawadi, Behnud and Plaß, Sabrina and Loer, Sabrina}}, issn = {{0014-2921}}, journal = {{European Economic Review}}, publisher = {{Elsevier BV}}, title = {{{“I don’t believe that you believe what I believe”: an experiment on misperceptions of social norms and whistleblowing}}}, doi = {{10.1016/j.euroecorev.2025.105189}}, volume = {{180}}, year = {{2025}}, } @inproceedings{65187, author = {{Keuchen, Marion and Lindemeyer, Sabine}}, booktitle = {{Rituale und Spiritualität - auch für religiös ungebundene Menschen}}, editor = {{Böhme, Thomas and Kuhlmann, Birgit and Meuche, Katrin and Wenk, Anne-Kathrin and Wittmann-Stasch, Bettina}}, isbn = {{978-3-943410-36-5}}, location = {{Hamburg}}, pages = {{68--79}}, publisher = {{Comenius-Institut}}, title = {{{Durch Schulseelsorge Demokratiefähigkeit bilden}}}, volume = {{11}}, year = {{2025}}, } @misc{65185, author = {{Keuchen, Marion}}, pages = {{60--61}}, publisher = {{Evangelische Kirche im Rheinland}}, title = {{{Dankbarkeitskoffer.
