Although the available lithography techniques are constantly being advanced to push the feature sizes down to the few-nanometer scale, such developments are associated with many technological and economic challenges. Combining established top-down lithography with bottom-up self-assembly strategies has the potential to overcome those challenges and enable the manipulation of matter with molecular precision. One of the most exciting approaches in this regard is to harness the programmability of DNA self-assembly to create precise DNA nanostructure masks to be used in the lithographic patterning of diverse substrates. DNA nanotechnology has provided us with a versatile toolbox for the high-yield synthesis of 2D and 3D nanostructures with complex, user-defined shapes at unprecedented molecular accuracy. Consequently, the last decade has seen intense research efforts aimed at transferring such DNA nanostructure shapes into functional organic and inorganic materials and we have now arrived at a point where sophisticated molecular lithography approaches utilize DNA nanostructure masks for the fabrication of plasmonic surfaces for metamaterials and sensing applications. This review summarizes how the spatial information of such DNA nanostructure masks can be transferred into various organic and inorganic materials through selective etching and deposition steps. The review also discusses recent developments toward all-purpose molecular lithography schemes and highlights promising extensions of the discussed methods toward new materials systems and application fields.</jats:p>","lang":"eng"}],"_id":"65108","publisher":"IOP Publishing","language":[{"iso":"eng"}],"user_id":"48864","doi":"10.1088/1361-6463/ae5667","year":"2026","title":"Molecular lithography with DNA nanostructures: Methods and applications","status":"public","author":[{"id":"48864","first_name":"Adrian Clemens","orcid":"0000-0001-7139-3110","last_name":"Keller","full_name":"Keller, Adrian Clemens"},{"full_name":"Linko, Veikko","first_name":"Veikko","last_name":"Linko"}],"publication_identifier":{"issn":["0022-3727","1361-6463"]},"publication_status":"published","date_updated":"2026-03-25T07:44:52Z"},{"place":"Tampere, Finland","date_created":"2026-03-27T15:20:54Z","type":"conference","keyword":["Join Queries","Acyclic Queries","Query Processing"],"oa":"1","department":[{"_id":"888"}],"publication":"Proceedings of the 28th International Workshop on Design, Optimization, Languages and Analytical Processing of Big Data (DOLAP 2026)","citation":{"mla":"Böhm, Daniela, et al. “Selective Use of Yannakakis’ Algorithm for Consistent Performance Gains.” <i>Proceedings of the 28th International Workshop on Design, Optimization, Languages and Analytical Processing of Big Data (DOLAP 2026)</i>, 2026.","bibtex":"@inproceedings{Böhm_Gottlob_Lanzinger_Longo_Okulmus_Pichler_Selzer_2026, place={Tampere, Finland}, title={Selective Use of Yannakakis’ Algorithm for Consistent Performance Gains}, booktitle={Proceedings of the 28th International Workshop on Design, Optimization, Languages and Analytical Processing of Big Data (DOLAP 2026)}, author={Böhm, Daniela and Gottlob, Georg and Lanzinger, Matthias and Longo, Davide Mario and Okulmus, Cem and Pichler, Reinhard and Selzer, Alexander}, year={2026} }","ama":"Böhm D, Gottlob G, Lanzinger M, et al.

This problem is particularly common for analytical queries, which aggregate data over many tables to produce a comparatively small final output, and queries on graph data, where intermediate results blow up quickly. Recent work inspired by Yannakakis’ algorithm approaches this by modifying the query engine to avoid materializing unnecessary tuples. However, this requires significant changes to the core of the system, which is not feasible in many situations such as cloud environments or proprietary systems.\r\nIn this work, we propose a flexible approach for optimizing long-running join queries from the outside of the DBMS. Rewriting-based realizations of Yannakakis’ algorithm suffer from inherent overhead due to the creation of intermediate tables. Thus, we present an approach for detecting and targeting queries which would benefit from a Yannakakis-style optimization. We introduce a new benchmark combining 5 standard benchmarks and augmenting them with additional instances, which provides a sufficient size and diversity for a machine learning based solution. On PostgreSQL, DuckDB and SparkSQL, slowdowns on queries where the rewriting is counterproductive are mostly avoided, as opposed to a naïve application of the rewriting, and we observe significant improvements in end-to-end runtimes over standard query execution and unconditional rewriting.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://ceur-ws.org/Vol-4186/paper2.pdf"}],"_id":"65178","language":[{"iso":"eng"}],"user_id":"114410","title":"Selective Use of Yannakakis’ Algorithm for Consistent Performance Gains","year":"2026","status":"public","author":[{"full_name":"Böhm, Daniela","last_name":"Böhm","first_name":"Daniela"},{"full_name":"Gottlob, Georg","first_name":"Georg","last_name":"Gottlob"},{"last_name":"Lanzinger","first_name":"Matthias","full_name":"Lanzinger, Matthias"},{"last_name":"Longo","first_name":"Davide Mario","full_name":"Longo, Davide Mario"},{"full_name":"Okulmus, Cem","orcid":"0000-0002-7742-0439","last_name":"Okulmus","first_name":"Cem","id":"114410"},{"first_name":"Reinhard","last_name":"Pichler","full_name":"Pichler, Reinhard"},{"full_name":"Selzer, Alexander","last_name":"Selzer","first_name":"Alexander"}],"date_updated":"2026-03-27T15:22:01Z"},{"quality_controlled":"1","citation":{"ieee":"A.

To this end, experiments are performed, which show the following characteristics: localization phenomena in the form of a shear band, softening behavior in the force‐displacement curve, and asymmetric behavior for compression and tension. To model this complex material behavior, a micromorphic continuum is used. In the present contribution, we focus on the linear‐elastic regime and demonstrate the identifiability of micromorphic material parameters under deliberately induced inhomogeneous deformation states. In addition to the degrees of freedom of a classical continuum, the micromorphic model has additional degrees of freedom, introduced here in a phenomenological sense to represent kinematically enriched deformation modes associated with the granular microstructure. Accordingly, the micromorphic fields are not interpreted as a separate physical scale (e.g., “binder” vs. “grains”), but as an effective continuum description at the specimen scale. This contribution addresses parameter identification for a micromorphic model of cold‐box sand, with a clear separation between homogeneous deformation states governing classical elastic parameters and inhomogeneous states required to activate and identify micromorphic length‐scale parameters. The main challenge lies in identifying the micro material parameters. To determine these, the corresponding gradient terms in the constitutive formulation must be triggered via properly tuned experiments. Micro‐parameter identification is demonstrated using synthetic data generated from a boundary‐value problem with inhomogeneous displacement fields. The chosen benchmark enables controlled activation of gradient terms and thereby renders optimization‐based identification of micromorphic parameters feasible. The synthetic example is deliberately chosen to assess feasibility and identifiability under controlled conditions, thereby isolating micromorphic identifiability aspects from experimental uncertainties. The novelty of the contribution lies in explicitly linking micromorphic parameter identifiability to kinematic inhomogeneity, and in demonstrating this link within a tractable forward– inverse setting for a linear‐elastic micromorphic continuum.</jats:p>","lang":"eng"}],"publication":"Proceedings in Applied Mathematics and Mechanics","issue":"2","doi":"10.1002/pamm.70093","article_number":"e70093","language":[{"iso":"eng"}],"date_updated":"2026-04-01T04:54:17Z","publication_status":"published","intvolume":"        26","title":"Aspects of Parameter Identification for a Micromorphic Continuum applied to a Cold‐Box Sand","year":"2026","publication_identifier":{"issn":["1617-7061","1617-7061"]},"author":[{"full_name":"Börger, Alexander","last_name":"Börger","first_name":"Alexander","id":"52037"},{"full_name":"Mahnken, Rolf","first_name":"Rolf","last_name":"Mahnken"},{"first_name":"Ismail","last_name":"Caylak","full_name":"Caylak, Ismail","id":"75"},{"first_name":"Richard","orcid":"0000-0003-2147-8444","last_name":"Ostwald","full_name":"Ostwald, Richard","id":"106876"}]},{"language":[{"iso":"eng"}],"_id":"61152","doi":"10.1145/3807510","user_id":"55631","publication_identifier":{"issn":["1936-7406"]},"author":[{"full_name":"Umuroglu, Yaman","last_name":"Umuroglu","first_name":"Yaman"},{"id":"98854","full_name":"Berganski, Christoph","first_name":"Christoph","last_name":"Berganski"},{"id":"55631","full_name":"Jentzsch, Felix","first_name":"Felix","orcid":"0000-0003-4987-5708","last_name":"Jentzsch"},{"full_name":"Danilowicz, Michal","last_name":"Danilowicz","first_name":"Michal"},{"full_name":"Kryjak, Tomasz","last_name":"Kryjak","first_name":"Tomasz"},{"last_name":"Bezaitis","first_name":"Charalampos","full_name":"Bezaitis, Charalampos"},{"first_name":"Magnus","last_name":"Sjalander","full_name":"Sjalander, Magnus"},{"full_name":"Colbert, Ian","first_name":"Ian","last_name":"Colbert"},{"last_name":"Preusser","first_name":"Thomas","full_name":"Preusser, Thomas"},{"full_name":"Petri-Koenig, Jakoba","first_name":"Jakoba","last_name":"Petri-Koenig"},{"last_name":"Blott","first_name":"Michaela","full_name":"Blott, Michaela"}],"status":"public","title":"SIRA: Scaled-Integer Range Analysis for Optimizing FPGA Dataflow Neural Network Accelerators","year":"2026","date_updated":"2026-04-27T14:13:50Z","publication_status":"submitted","date_created":"2025-09-08T14:10:39Z","department":[{"_id":"78"}],"type":"journal_article","citation":{"apa":"Umuroglu, Y., Berganski, C., Jentzsch, F., Danilowicz, M., Kryjak, T., Bezaitis, C., Sjalander, M., Colbert, I., Preusser, T., Petri-Koenig, J., &#38; Blott, M.

Addressing such bottlenecks requires a comprehensive approach to tailoring the precision across operations in the inference computation. To this end, we introduce scaled-integer range analysis (SIRA), a static analysis technique employing interval arithmetic to determine the range, scale, and bias for tensors in quantized neural networks. We show how this information can be exploited to reduce the resource footprint of FPGA dataflow neural network accelerators via tailored bitwidth adaptation for accumulators and downstream operations, aggregation of scales and biases, and conversion of consecutive elementwise operations to thresholding operations. We integrate SIRA-driven optimizations into the open-source FINN framework, then evaluate their effectiveness across a range of quantized neural network workloads and compare implementation alternatives for non-matrix-multiply operations. We demonstrate an average reduction of 17\\% for LUTs, 66\\% for DSPs, and 22\\% for accumulator bitwidths with SIRA optimizations, providing detailed benchmark analysis and analytical models to guide the implementation style for non-matrix layers. Finally, we open-source SIRA to facilitate community exploration of its benefits across various applications and hardware platforms."}]},{"language":[{"iso":"eng"}],"series_title":"Smart Technologies for an All-Electric Society","doi":"10.1007/978-3-032-07319-8_19","title":"Designing and Evaluating the Usability and Onboarding for a Mixed-Reality Application: A Case Study with PEARL (Paderborn Electrical Engineering AR Laboratory) and Meta Quest 3","year":"2026","publication_identifier":{"isbn":["9783032073181","9783032073198"],"issn":["2367-3370","2367-3389"]},"author":[{"full_name":"Alptekin, Mesut","last_name":"Alptekin","first_name":"Mesut","orcid":"0009-0004-8545-1165","id":"11763"},{"first_name":"Daniel","last_name":"Münstermann","full_name":"Münstermann, Daniel"},{"first_name":"Katrin","last_name":"Temmen","full_name":"Temmen, Katrin"}],"date_updated":"2026-04-29T09:23:02Z","publication_status":"published","intvolume":"         2","date_created":"2026-04-29T09:12:41Z","keyword":["Meta Quest 3","Augmented Reality","Mixed Reality","PEARL","Electrical Engineering","Laboratory Training","Onboarding","User Experience","User Interface","Heuristics"],"type":"book_chapter","department":[{"_id":"34"},{"_id":"3"},{"_id":"300"}],"publication":"Lecture Notes in Networks and Systems","abstract":[{"text":"Abstract This study explores the usability and onboarding process of a Mixed Reality (MR) application called PEARL, designed to prepare students for laboratory work. Originally developed for mobile Augmented Reality (mAR), PEARL was adapted for MR to offer a more immersive and intuitive experience through hand and gesture controls. Since many students lack experience with MR devices, a user-friendly onboarding system is essential. The study aims to redesign PEARL’s user interface and onboarding experience, evaluating how intuitive interaction elements impact usability. First, a literature review will identify existing usability guidelines for MR applications, which will guide the redesign of the interface. This new version will then be tested with students through a user study. Feedback will be collected via an online survey to assess the onboarding and user experience, and the findings will be used to refine the design further. The expected outcome is an improved onboarding process and interface, making PEARL accessible even for MR novices, enhancing their ability to interact with 3D objects in a real-world setting. Ultimately, the study aims to provide best practices for developing intuitive MR interfaces and effective onboarding experiences, especially in educational contexts.","lang":"eng"}],"page":"199-211","_id":"65515","publisher":"Springer Nature Switzerland","user_id":"11763","volume":2,"status":"public","conference":{"end_date":"2025-04-11","start_date":"2025-04-09","name":"International Conference on Smart Technologies & Education (STE2025)","location":"Santiago, Chile"},"place":"Cham","citation":{"apa":"Alptekin, M., Münstermann, D., &#38; Temmen, K.

Particularly, the reliance on fossil fuels for process heat supply is a key factor for CO2-emissions. Electrically driven compression heat pumps are a promising option to reduce fossil fuel consumption by upgrading low-temperature waste heat to a higher temperature level, provided that low-carbon electricity is available. However, the integration of heat pumps into chemical utility systems remains a challenge due to economic constraints and the high complexity associated with site-wide heat integration and retrofit of existing structures. This work presents a mixed-integer linear programming (MILP) approach for the optimization of utility systems with integrated heat pumps. To address computational complexity, candidate utility temperature levels are pre-selected, and feasible heat pump coefficients of performance (COP) are precomputed. The framework is applied to both greenfield and retrofit scenarios for a synthetic case study consisting of 400 process streams. In the greenfield scenario, optimal utility temperature levels and heat pump integration configurations are identified. For the retrofit scenario, temperature levels of an existing utility system are modified to reduce total annual costs (TAC). Additionally, sensitivity analysis is conducted to assess the influence of key economic and environmental parameters. The presented case studies demonstrate short solution times, highlighting the suitability of the proposed framework for screening studies and systematic sensitivity analyses in early-stage design and retrofit applications.</jats:p>"}],"publication":"Systems and Control Transactions","type":"conference","department":[{"_id":"831"}],"date_created":"2026-06-22T11:32:30Z","publication_status":"published","date_updated":"2026-06-22T11:33:05Z","intvolume":"         6","year":"2026","title":"Optimization of Site-wide Heat-Integrated Utility Systems with Heat Pumps using MILP","author":[{"full_name":"Hochhaus, Thorben","last_name":"Hochhaus","first_name":"Thorben"},{"last_name":"Grünewald","first_name":"Marcus","full_name":"Grünewald, Marcus"},{"id":"101499","first_name":"Julia","last_name":"Riese","orcid":"0000-0002-3053-0534","full_name":"Riese, Julia"}],"publication_identifier":{"issn":["2818-4734"]},"doi":"10.69997/sct.152209","language":[{"iso":"eng"}],"quality_controlled":"1","citation":{"bibtex":"@inproceedings{Hochhaus_Grünewald_Riese_2026, title={Optimization of Site-wide Heat-Integrated Utility Systems with Heat Pumps using MILP}, volume={6}, DOI={<a href=\"https://doi.org/10.69997/sct.152209\">10.69997/sct.152209</a>}, booktitle={Systems and Control Transactions}, publisher={PSE Press}, author={Hochhaus, Thorben and Grünewald, Marcus and Riese, Julia}, year={2026} }","ama":"Hochhaus T, Grünewald M, Riese J.

Currently, the installation of blind rivet nuts still requires pre-drilling using chip-forming operations. In Meschut and Meyer (Vorlochfreies Setzen von Funktionselementen mittels Fließformen, Europäische Forschungsgesellschaft für Blechverarbeitung e.V. (EFB), Hannover, 2021), a chipless, two-step method for installing blind rivet nuts was developed, in which flow-drilling is the initial step. To eliminate the pre-drilling operation and optimise the joining process of blind rivet nuts, a pilot-hole-free joining method using a flow-drilling process is being pursued. The use of these blind rivet nuts can significantly simplify the joining process by eliminating chip-forming pre-drilling operations. Additionally, the screw-through capability reduces screw variance in automated fastening, optimising the feeding process by minimising the risk of incorrect screw selection. This work aims to develop a single-step process for the installation of a blind rivet nut. To achieve this, it is necessary to design the geometries of both the blind rivet nut and the flow-drill former, which also serves as the mandrel for the blind rivet nut. In addition to the geometries of the tools and functional elements, the flow-drilling process itself has been developed. Special attention is given to the pull-through and the formation of the closing head. To optimise the closing head formation, an iterative optimization process was used. The quality of the pull-through is improved by varying the tip geometries and adjusting the process parameters during flow-drilling.</jats:p>","lang":"eng"}],"date_created":"2026-07-31T07:00:58Z","type":"journal_article","title":"Single-stage setting of blind rivet nuts without pre-drilling","year":"2026","author":[{"id":"84119","first_name":"Yannic","last_name":"Böhm","full_name":"Böhm, Yannic"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"}],"publication_identifier":{"issn":["2731-6564"]},"publication_status":"published","date_updated":"2026-07-31T07:04:13Z","intvolume":"         5","article_number":"121","language":[{"iso":"eng"}],"doi":"10.1007/s44245-026-00222-x","citation":{"short":"Y.

A major engineering challenge is the optimization of the fixed‐bed reactor design, specifically the heat dissipation in regions of high reaction heat release. A mitigation concept is the introduction of inert material into the fixed bed, called catalyst dilution. In this study, a 1D continuity model is presented, which aims to predict catalyst superheating. This model is used in an exploratory study to identify system sensitivity and optimization parameters. Subsequently, an optimization framework for improving the reactor design is tested, resulting in a 148‐K reduction in peak catalyst temperature when using a 33.3 vol% catalyst dilution.\r\n                  </jats:p>","lang":"eng"}],"date_created":"2026-08-20T15:44:11Z","type":"journal_article","department":[{"_id":"831"}]},{"department":[{"_id":"819"}],"type":"conference","date_created":"2026-07-01T12:13:34Z","citation":{"ieee":"U.

Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways. These results provide process‐enabled guidelines for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies."}],"publication":"Laser &amp; Photonics Reviews","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"date_created":"2026-08-03T06:43:03Z"},{"editor":[{"full_name":"Trujillo, Leonardo","first_name":"Leonardo","last_name":"Trujillo"},{"last_name":"Hu","first_name":"Ting","full_name":"Hu, Ting"}],"doi":"10.1145/3795095.3805136","user_id":"15504","publisher":"ACM","_id":"66670","language":[{"iso":"eng"}],"page":"134–142","date_updated":"2026-08-06T07:00:02Z","author":[{"full_name":"Mensendiek, Carolin","last_name":"Mensendiek","first_name":"Carolin","id":"75006"},{"last_name":"Preuß","orcid":"0009-0008-9308-2418","first_name":"Oliver Ludger","full_name":"Preuß, Oliver Ludger","id":"102978"},{"id":"102977","full_name":"Rook, Jeroen","last_name":"Rook","first_name":"Jeroen"},{"last_name":"Chicano","first_name":"Francisco","full_name":"Chicano, Francisco"},{"last_name":"Whitley","first_name":"Darrell","full_name":"Whitley, Darrell"},{"id":"100740","first_name":"Heike","orcid":"0000-0002-9788-8282","last_name":"Trautmann","full_name":"Trautmann, Heike"}],"status":"public","year":"2026","title":"Digging to the Ground Truth: Solving Multi-objective Gray-Box Optimization Problems through Hyperplane Elimination","department":[{"_id":"819"}],"type":"conference","date_created":"2026-08-06T06:59:20Z","citation":{"ieee":"C.

We consider semidefinite programs (SDPs) that approximate the maximum acceptance probability of a measurement over separable states, the optimization problem underlying QMA(2). In the extended-formulation model of Harrow, Natarajan, and Wu (HNW), all measurements share a common feasible region and an objective-independent embedding of product states that exactly reproduces their acceptance probabilities. For every $0<θ<2/7$, there are constants $c_θ,a_θ>0$ such that, for sufficiently large $d$, any such SDP with uniform additive error $0<a\\le a_θ$ has size at least $d^{c_θ\\min\\{a^{-1/3},d^θ\\}}$. The bound applies at sufficiently small constant error, is superpolynomial in $d$ whenever $a=o(1)$, and becomes $d^{Ω(d^θ)}$ when $a\\le d^{-3θ}$, improving HNW's quasipolynomial bound at inverse- square error. The same bound holds for any SDP-representable convex set of states that contains all separable states and lies within trace distance $a$ of them, giving a quantitative counterpart to Fawzi's theorem that the separable set has no exact semidefinite representation. Our proof combines the quantitative pseudo-density theorem of Lee, Raghavendra, and Steurer with explicit block-positive operators and Chebyshev amplification. Our main results are supported by Lean proofs."}],"date_created":"2026-09-09T12:06:36Z","external_id":{"arxiv":["2609.09033"]},"type":"preprint"}]
