As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the wavelength domain without any guardband as a part of a Nyquist-WDM superchannel. These superchannels can be additionally multiplexed in space and polarization. Thus, the presented demonstration can open a new possibility for the detection of multidimensional parallel data signals with silicon photonics. No external pulse source is needed for the receiver, and frequency-time coherence is used to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse sequences. All parameters are completely tunable in the electrical domain. The feasibility of the scheme is demonstrated through a proof-of-concept experiment over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal due to experimental constraints on the transmitter side electronics. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect symbol rates up to 90 GBd in an integrated Nyquist receiver.</jats:p>"}],"publication":"Optics Express","language":[{"iso":"eng"}],"year":"2022","issue":"8","title":"Reconfigurable and real-time high-bandwidth Nyquist signal detection with low-bandwidth in silicon photonics","publisher":"Optica Publishing Group","date_created":"2022-12-06T10:59:03Z"},{"citation":{"chicago":"Misra, Arijit, Karanveer Singh, Janosch Meier, Christian Kress, Tobias Schwabe, Stefan Preussler, J.

However, when experimenting with different problem formulations or when prototyping new algorithms, a major practical obstacle is the need to figure out derivatives of objective functions, especially when second‐order derivatives are required. Deriving and manually implementing gradients and Hessians is both time‐consuming and error‐prone. Automatic differentiation techniques address this problem, but can introduce a diverse set of obstacles themselves, e.g. limiting the set of supported language features, imposing restrictions on a program's control flow, incurring a significant run time overhead, or making it hard to exploit sparsity patterns common in geometry processing. We show that for many geometric problems, in particular on meshes, the simplest form of forward‐mode automatic differentiation is not only the most flexible, but also actually the most efficient choice. We introduce TinyAD: a lightweight C++ library that automatically computes gradients and Hessians, in particular of sparse problems, by differentiating small (tiny) sub‐problems. Its simplicity enables easy integration; no restrictions on, e.g., looping and branching are imposed. TinyAD provides the basic ingredients to quickly implement first and second order Newton‐style solvers, allowing for flexible adjustment of both problem formulations and solver details. By showcasing compact implementations of methods from parametrization, deformation, and direction field design, we demonstrate how TinyAD lowers the barrier to exploring non‐linear optimization techniques. This enables not only fast prototyping of new research ideas, but also improves replicability of existing algorithms in geometry processing. TinyAD is available to the community as an open source library.</jats:p>","lang":"eng"}],"publication":"Computer Graphics Forum","doi":"10.1111/cgf.14607","volume":41,"author":[{"first_name":"Patrick","full_name":"Schmidt, Patrick","last_name":"Schmidt"},{"full_name":"Born, Janis","last_name":"Born","first_name":"Janis"},{"full_name":"Bommes, David","last_name":"Bommes","first_name":"David"},{"first_name":"Marcel","id":"114904","full_name":"Campen, Marcel","orcid":"0000-0003-2340-3462","last_name":"Campen"},{"last_name":"Kobbelt","full_name":"Kobbelt, Leif","first_name":"Leif"}],"date_updated":"2025-07-14T12:47:14Z","page":"113-124","intvolume":"        41","citation":{"chicago":"Schmidt, Patrick, Janis Born, David Bommes, Marcel Campen, and Leif Kobbelt. “TinyAD: Automatic Differentiation in Geometry Processing Made Simple.” <i>Computer Graphics Forum</i> 41, no. 5 (2022): 113–24. <a href=\"https://doi.org/10.1111/cgf.14607\">https://doi.org/10.1111/cgf.14607</a>.","ieee":"P.

In this context, an important advance has been the replacement of error-prone rounding in the generation of integer-grid maps, by robust quantization methods. In parallel, parametrization-based hex mesh generation for volumes has been advanced. In this volumetric context, however, the state-of-the-art still relies on fragile rounding, not rarely producing defective meshes, especially when targeting a coarse mesh resolution. We present a method to robustly quantize volume parametrizations, i.e., to determine guaranteed valid choices of integers for 3D integer-grid maps. Inspired by the 2D case, we base our construction on a non-conforming cell decomposition of the volume, a 3D analogue of a T-mesh. In particular, we leverage the motorcycle complex, a recent generalization of the motorcycle graph, for this purpose. Integer values are expressed in a differential manner on the edges of this complex, enabling the efficient formulation of the conditions required to strictly prevent forcing the map into degeneration. Applying our method in the context of hexahedral meshing, we demonstrate that hexahedral meshes can be generated with significantly improved flexibility.</jats:p>","lang":"eng"}],"author":[{"full_name":"Brückler, Hendrik","id":"115694","last_name":"Brückler","first_name":"Hendrik"},{"first_name":"David","full_name":"Bommes, David","last_name":"Bommes"},{"id":"114904","full_name":"Campen, Marcel","orcid":"0000-0003-2340-3462","last_name":"Campen","first_name":"Marcel"}],"volume":41,"date_updated":"2025-07-14T12:47:23Z","doi":"10.1145/3528223.3530123","publication_status":"published","publication_identifier":{"issn":["0730-0301","1557-7368"]},"citation":{"mla":"Brückler, Hendrik, et al. “Volume Parametrization Quantization for Hexahedral Meshing.” <i>ACM Transactions on Graphics</i>, vol. 41, no. 4, Association for Computing Machinery (ACM), 2022, pp. 1–19, doi:<a href=\"https://doi.org/10.1145/3528223.3530123\">10.1145/3528223.3530123</a>.","bibtex":"@article{Brückler_Bommes_Campen_2022, title={Volume parametrization quantization for hexahedral meshing}, volume={41}, DOI={<a href=\"https://doi.org/10.1145/3528223.3530123\">10.1145/3528223.3530123</a>}, number={4}, journal={ACM Transactions on Graphics}, publisher={Association for Computing Machinery (ACM)}, author={Brückler, Hendrik and Bommes, David and Campen, Marcel}, year={2022}, pages={1–19} }","short":"H.

Although some predictors within the family (e.g., structural factors) are widely researched, comprehensive results on the influence of parental involvement, especially parental instruction as a form of parental support during information-related internet activities, on different internet uses are still lacking. Therefore, the study investigates (1) the relationship of parental role construction, self-efficacy, internet skills, and parental instruction in information-related internet use perceived by parents and children and (2) the relationship of parental role construction, self-efficacy, internet skills, parental instruction, and children's internet uses at home (entertainment-related, practical and school-or-learning-related). The mediation effects of parental instruction were also tested. A paper-and-pencil questionnaire was answered by 361 German children and their parents. Structural equation modeling was applied to answer the research questions. We observed that children's perceived parental instruction was positively associated with children's practical and school-or-learning-related internet use.

In this study, the interactions of different welding current levels and weld times on the tendency for LME cracking in third-generation AHSSs were investigated. LME manifested itself as high-penetration cracks around the circumference of the spot welds for welding currents closely below the expulsion limit. At the same time, the observed tendency for LME cracking showed no direct correlation with the overall heat input of the investigated welding processes. To identify a reliable indicator of the tendency for LME cracking, the local strain rate at the origin of the observed cracks was analyzed over the course of the welding process via finite element simulation. While the local strain rate showed a good correlation with the process-specific LME cracking tendency, it was difficult to interpret due to its discontinuous course. Therefore, based on the experimental measurement of electrode displacement during welding, electrode indentation velocity was proposed as a descriptive indicator for quantifying cracking tendency.</jats:p>"}],"publication":"Welding Journal","title":"The Influence of Electrode Indentation Rate on LME Formation during RSW","date_created":"2024-03-18T11:51:57Z","publisher":"American Welding Society","year":"2022","issue":"7","quality_controlled":"1"},{"publication":"Medienimpulse","type":"journal_article","status":"public","_id":"35143","project":[{"name":"DigHomE: DigHomE: Digital Home Learning Environment – Gelingensbedingungen elterlicher Unterstützung bei der informationsorientierten Internetnutzung","_id":"378","grant_number":"01JD1814A"}],"department":[{"_id":"427"}],"user_id":"90826","language":[{"iso":"ger"}],"publication_status":"published","issue":"4","year":"2022","intvolume":"        60","citation":{"apa":"Bonanati, S., Buhl, H.
