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." author: - first_name: Adrian Clemens full_name: Keller, Adrian Clemens id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 - first_name: Veikko full_name: Linko, Veikko last_name: Linko citation: ama: 'Keller AC, Linko V.

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." author: - first_name: Daniela full_name: Böhm, Daniela last_name: Böhm - first_name: Georg full_name: Gottlob, Georg last_name: Gottlob - first_name: Matthias full_name: Lanzinger, Matthias last_name: Lanzinger - first_name: Davide Mario full_name: Longo, Davide Mario last_name: Longo - first_name: Cem full_name: Okulmus, Cem id: '114410' last_name: Okulmus orcid: 0000-0002-7742-0439 - first_name: Reinhard full_name: Pichler, Reinhard last_name: Pichler - first_name: Alexander full_name: Selzer, Alexander last_name: Selzer citation: ama: 'Böhm D, Gottlob G, Lanzinger M, et al.

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." article_number: e70093 author: - first_name: Alexander full_name: Börger, Alexander id: '52037' last_name: Börger - first_name: Rolf full_name: Mahnken, Rolf last_name: Mahnken - first_name: Ismail full_name: Caylak, Ismail id: '75' last_name: Caylak - first_name: Richard full_name: Ostwald, Richard id: '106876' last_name: Ostwald orcid: 0000-0003-2147-8444 citation: ama: Börger A, Mahnken R, Caylak I, Ostwald R.

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. author: - first_name: Yaman full_name: Umuroglu, Yaman last_name: Umuroglu - first_name: Christoph full_name: Berganski, Christoph id: '98854' last_name: Berganski - first_name: Felix full_name: Jentzsch, Felix id: '55631' last_name: Jentzsch orcid: 0000-0003-4987-5708 - first_name: Michal full_name: Danilowicz, Michal last_name: Danilowicz - first_name: Tomasz full_name: Kryjak, Tomasz last_name: Kryjak - first_name: Charalampos full_name: Bezaitis, Charalampos last_name: Bezaitis - first_name: Magnus full_name: Sjalander, Magnus last_name: Sjalander - first_name: Ian full_name: Colbert, Ian last_name: Colbert - first_name: Thomas full_name: Preusser, Thomas last_name: Preusser - first_name: Jakoba full_name: Petri-Koenig, Jakoba last_name: Petri-Koenig - first_name: Michaela full_name: Blott, Michaela last_name: Blott citation: ama: 'Umuroglu Y, Berganski C, Jentzsch F, et al.

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. author: - first_name: Mesut full_name: Alptekin, Mesut id: '11763' last_name: Alptekin orcid: 0009-0004-8545-1165 - first_name: Daniel full_name: Münstermann, Daniel last_name: Münstermann - first_name: Katrin full_name: Temmen, Katrin last_name: Temmen citation: ama: 'Alptekin M, Münstermann D, Temmen K.

Damit einhergehende Erwartungen im Hinblick auf den Professionalisierungsprozess von Lehrkräften fokussieren insbesondere die Vermittlung einer forschenden Grundhaltung, die auf eine nicht-wissenschaftsferne Berufsausübung abzielt. Wir fassen die forschende Grundhaltung als Professionsüberzeugung, die aus einer kognitiven, affektiven und handlungsbezogenen Komponente besteht und untersuchen die Komponenten im Zusammenspiel sowie im Längsschnitt.\r\n \ Mittels teilstrukturierter Interviews mit 22 angehenden Lehrkräften im Referendariat und Berufseinstieg, die sich im Praxissemester mit Forschendem Lernen befasst haben, werden das Verständnis (kognitive Komponente) und die Bedeutsamkeit (affektive und handlungsbezogene Komponente) Forschenden Lernens in der jeweiligen Ausbildungs- bzw. Berufsphase erfragt. Die Daten werden inhaltsanalytisch sowie typenbildend ausgewertet, um das Verständnis und die Bedeutsamkeit in der jeweiligen Phase, längsschnittliche Entwicklungen sowie das Verhältnis von Verständnis und Bedeutsamkeit herauszuarbeiten. Die Befunde zeigen, dass die Verständnisse von Forschendem Lernen sowohl im Referendariat als auch im Berufseinstieg variieren. Zudem ist das Konzept – laut Schilderungen der Befragten – durchaus bedeutsam für ihre Lern- und Handlungspraxis, jedoch nicht für alle und in unterschiedlich ausgeprägter Form. Die Typenbildung verdeutlicht, dass die fehlende Bedeutsamkeit Forschenden Lernens mit Fehlkonzepten einhergeht und eine höhere Bedeutsamkeit erkennbar ist, wenn Adaptionsleistungen hinsichtlich des Konzepts vorgenommen werden. Insgesamt ist im Sinne der Auffassung als Professionsüberzeugung die Anbahnung einer forschenden Grundhaltung bei einigen Befragten erkennbar. Implikationen für eine künftige Hochschulbildung ergeben sich u. a. mit Blick auf die Unterstützung von Studierenden bei Adaptionsleistungen für die (jeweilige) Praxis." alternative_title: - Perspectives of prospective teachers on research-based learning—a qualitative longitudinal study during teacher training and career entry author: - first_name: Martina full_name: Homt, Martina id: '11674' last_name: Homt - first_name: Bea full_name: Bloh, Bea id: '69910' last_name: Bloh - first_name: Janis full_name: Wehde, Janis id: '82257' last_name: Wehde orcid: 0009-0008-0720-7828 citation: ama: Homt M, Bloh B, Wehde J.

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. author: - first_name: Thorben full_name: Hochhaus, Thorben last_name: Hochhaus - first_name: Marcus full_name: Grünewald, Marcus last_name: Grünewald - first_name: Julia full_name: Riese, Julia id: '101499' last_name: Riese orcid: 0000-0002-3053-0534 citation: ama: 'Hochhaus T, Grünewald M, Riese J.

By modeling all signal and noise contributions to the measurement, we derive a single numerical value that describes the sensitivity of the ETPA measurement in Göppert-Mayer units. This allows us to directly compare vastly different experimental approaches and determine whether ETPA will be detectable under the given conditions. Therefore we can quantify the effect of any change to a given experimental apparatus and identify the ideal optimization pathway. article_number: '013718' article_type: original author: - first_name: René full_name: Pollmann, René id: '78890' last_name: Pollmann - first_name: Franz full_name: Roeder, Franz id: '88149' last_name: Roeder - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' citation: ama: Pollmann R, Roeder F, Silberhorn C, Brecht B.

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." article_number: '121' author: - first_name: Yannic full_name: Böhm, Yannic id: '84119' last_name: Böhm - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 citation: ama: Böhm Y, Meschut G.

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 " article_number: e70162 article_type: original author: - first_name: Torben full_name: Schmücker, Torben id: '111274' last_name: Schmücker - first_name: Julia full_name: Riese, Julia id: '101499' last_name: Riese orcid: 0000-0002-3053-0534 citation: ama: Schmücker T, Riese J.

In response to this, various pathways into vocational \r\nteacher education have been established. These pathways are diverse in their nature but all lead to \r\nthe same teacher degree as traditional teacher education. In two interview studies (n=22 (pre\r\nservice) vocational teachers), initial motives of entering teacher education (based on FIT-Choice) \r\nas well as retrospective views on the career choice after entering the profession (based on PLP\r\nmodel) are analyzed. The present study compares the reflective views of pre-service teachers and \r\ncareer-changing in-service teachers (CCIT). Although both groups generally perceive their career \r\nchoice positively, the results raise questions about why CCITs did not enter the field of teacher \r\neducation in the first place. Additionally, the analysis allows for further discussion about existing \r\nteacher education programs in times of teacher shortage." author: - first_name: Mats full_name: Vernholz, Mats id: '76955' last_name: Vernholz orcid: 0000-0001-5175-357X - first_name: Gabriela full_name: Jonas-Ahrend, Gabriela id: '77633' last_name: Jonas-Ahrend orcid: 0000-0003-3898-954X - first_name: Katrin full_name: Temmen, Katrin last_name: Temmen citation: ama: 'Vernholz M, Jonas-Ahrend G, Temmen K.

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. article_number: e71686 article_type: original author: - first_name: Vasanthan full_name: Devaraj, Vasanthan id: '103814' last_name: Devaraj - first_name: Sunghyun full_name: Kwak, Sunghyun last_name: Kwak - first_name: Hyeongjip full_name: Kim, Hyeongjip last_name: Kim - first_name: Sang‐Keun full_name: Sung, Sang‐Keun last_name: Sung - first_name: Jong‐Min full_name: Lee, Jong‐Min last_name: Lee - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Won‐Geun full_name: Kim, Won‐Geun last_name: Kim citation: ama: Devaraj V, Kwak S, Kim H, et al.
