We review in particular our work on both time- and frequency-domain approaches and give an outlook on how these architectures can be extended to include further signal processing tasks such as equalization. Optically triggered track-and-hold amplifiers are reported with an equivalent jitter below 80 fs rms in a signal frequency range from 20 GHz to 70 GHz. Frequency-domain architectures implementing optical arbitrary waveform measurement up to signal bandwidths of 610 GHz are also shown. Finally, an architecture allowing the deserialization and equalization of PAM4 signals is introduced and modeled for operation in 400 Gb/s links.}}, author = {{Witzens, Jeremy and Drayss, Daniel and Fang, Dengyang and Moscoso Mártir, Alvaro and Müller, Juliana and Weizel, Maxim and Zazzi, Andrea and Freude, Wolfgang and Koos, Christian and Randel, Sebastian and Scheytt, J.

Possible architectures of PONyDAC are derived and compared in terms of performance and practicability. Moreover, the limits of PONyDAC systems and their superiority over classical electronic DACs are discussed. Furthermore, discrete building-block based implementations and monolithic implementations in electronic-photonic integrated circuits (EPICs) are presented. To enable a practicable monolithic integration, a shrinkage of the Mach-Zehnder modulators (MZMs) has been performed by applying forward-biased phase shifters (FB-PSs). These FB-PSs are analyzed and modeled to allow the precise and reliable design of PONyDAC systems with multiple MZMs. Finally, data conversion and data transmission experiments are carried out to demonstrate the systems functionality, quantify its performance, and prove their superiority over purely electronic DACs.}}, author = {{Scheytt, J.

We show that even for the elegantly simple classical shadow protocol of [Huang, Kueng, Preskill, Nature Physics 2020] utilizing local Clifford measurements, CSV is QMA-complete.

This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.}}, author = {{Hacker, Konrad and Juricke, Emilia and Münch, Carolin and Suma, Antonio and Keller, Adrian Clemens and Zhang, Yixin}}, issn = {{1613-6810}}, journal = {{Small}}, publisher = {{Wiley}}, title = {{{Global Quantitative Analysis of Ligation Reactions in Self‐Assembled DNA Nanostructures at the Single‐Nick Level}}}, doi = {{10.1002/smll.202508136}}, year = {{2026}}, } @unpublished{65544, author = {{Knauff, Markus and Butz, Martin V. and Kaup, Barbara and Kunde, Wilfried and Scharlau, Ingrid}}, booktitle = {{psyarxiv}}, keywords = {{explainability, explanation, prediction}}, pages = {{18}}, publisher = {{OSF}}, title = {{{When prediction replaces explanation: A threat to psychological science }}}, year = {{2026}}, } @inproceedings{65547, abstract = {{Process mining proved to be valuable for enabling transparency in business processes and to help to manage the everyday process dynamics.

Computational Thinking (CT) has become a central theme in K–12 Computer Science education. Over the past twenty years, multiple conceptualizations of CT have emerged, many forming the basis for assessment instruments. One such conceptualization was developed for the large-scale International Computer and Information Literacy Study (ICILS), which assessed CT across 24 countries using representative sampling. The size and sampling quality of the ICILS data set allow for robust statistical analyses which in turn will be of interest to researchers and policy-makers alike. This study situates the ICILS 2023 conceptualization of CT within other established frameworks and conducts a secondary analysis of the ICILS 2023 CT data on non-cognitive antecedents and processes. Methods . Structured deductive content analyses compare the ICILS 2023 items with those from the Bebras Challenge on Informatics and Computational Thinking [13] ( Bebras ) and the Computational Thinking Test [55]) ( CTt ), mapped across three CT frameworks—ICILS [28], Shute et al. [65] and Weintrop et al. [71]—and aligned with Bloom's revised taxonomy [2]. Linear regression analyses on the data of the 20 educational contexts that provided not only CT performance data but also a complete coverage of student data relative to the predictors of CT performance studied in prior work examine the predictive effect of non-cognitive factors on CT performance. Results . The qualitative analyses showed that the ICILS 2023 CT items can be mapped to existing frameworks. Conversely, items from both Bebras and CTt can be mapped to the ICILS framework. The distinct, partially overlapping profiles of the instruments across the frameworks as well as Bloom's taxonomy indicate that they are complementary in assessing CT, confirming and expanding prior comparisons of Bebras and CTt . The regression analyses indicate no single dominant predictor of CT performance. The association of socio-economic status, gender, or the home language was consistent with prior findings, predictors related to learning processes, however, vary across educational contexts. Discussion . Our results demonstrate that ICILS 2023 items can be mapped onto multiple established CT frameworks, supporting their broader validity and utility for comparative research. The findings of the regression analysis underscore the complex interplay of non-cognitive factors affecting CT and illustrate the significance of contextual interpretation within educational systems. }}, author = {{Vahrenhold, Jan and Niemann, Jan and Drossel, Kerstin}}, issn = {{1946-6226}}, journal = {{ACM Transactions on Computing Education}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Computational Thinking in ICILS 2023: Analyzing the Construct and Its Antecedent- and Process-Level Predictors}}}, doi = {{10.1145/3813115}}, year = {{2026}}, } @article{65554, abstract = {{Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction, while supporting not only contractible but also incontractible loops on the boundaries of manifold objects of higher genus and arbitrary non‐trivial topology. We describe an implementation of this algorithm in the discrete setting, with triangle mesh cut surfaces embedded in tetrahedral mesh objects. Making use of this novel cutting algorithm, we describe a method for the reliable construction of bijective volumetric maps between solid objects, demonstrating the algorithm's utility. This mapping method overcomes restrictions of the state of the art to topological balls, extending coverage to objects of arbitrary genus, specifically so‐called 1 ‐handlebodies. }}, author = {{Hinderink, Steffen and Campen, Marcel}}, issn = {{0167-7055}}, journal = {{Computer Graphics Forum}}, publisher = {{Wiley}}, title = {{{DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping}}}, doi = {{10.1111/cgf.70379}}, year = {{2026}}, }
