@article{66838, abstract = {{The sliding square model is a widely used abstraction for studying self-reconfigurable robotic systems, where modules are square-shaped robots that move by sliding or rotating over one another. In this paper, we propose a novel distributed algorithm that enables a group of modules to reconfigure into a rhombus shape, starting from an arbitrary side-connected configuration. It is connectivity-preserving and operates under minimal assumptions: one leader module, common chirality, constant memory per module, and visibility and communication restricted to immediate neighbors. Unlike prior work, which relaxes the original sliding square move-set, our approach uses the unmodified move-set, addressing the additional challenge of handling locked configurations. Our algorithm is sequential in nature and operates with a worst-case time complexity of O(n^2) rounds, which is optimal for sequential algorithms. To improve runtime, we introduce two parallel variants of the algorithm. Both rely on a spanning tree data structure, allowing modules to make decisions based on local connectivity. Our experimental results show a significant speedup for the first variant, and a linear average runtime for the second variant, which is worst-case optimal for parallel algorithms.}}, author = {{Kostitsyna, Irina and Liedtke, David and Scheideler, Christian}}, issn = {{0304-3975}}, journal = {{Theoretical Computer Science}}, keywords = {{modular robots, distributed algorithms, sliding squares}}, publisher = {{Elsevier BV}}, title = {{{Distributed rhombus formation of sliding squares}}}, doi = {{10.1016/j.tcs.2026.116196}}, volume = {{1085}}, year = {{2026}}, } @article{66840, author = {{Danner, Christian and Lagarden, Martin and Martini, Jan Thomas and Niemann, Rainer and Oestreicher, Andreas and Sassmann, Juliane and Schreiber, Ulrich and Simons, Dirk and Sureth-Sloane, Caren and Voeller, Dennis}}, journal = {{International Transfer Pricing Journal}}, number = {{5}}, title = {{{Mandatory Binding Arbitration – Economic Evaluation of an International Norm}}}, doi = {{10.59403/pmxpqx}}, volume = {{33}}, year = {{2026}}, } @article{66839, author = {{Koch, Reinald and Sureth-Sloane, Caren}}, journal = {{Der Betrieb}}, number = {{35}}, pages = {{2110--2177}}, title = {{{Steuern und Zölle als strategische Entscheidungsgrößen: Wirkungen auf Investitionen, Lieferketten und den Standort Deutschland}}}, volume = {{79}}, year = {{2026}}, } @article{65894, abstract = {{We examine the relation between voluntary audit and the cost of debt in private firms.

To address this challenge, we present a methodological framework that embeds the visual world paradigm (VWP) within a continuous, goal-directed human–robot interaction (HRI) task. By augmenting VWP in an HRI setup to produce standardized yet responsive verbal and non-verbal behaviours, the framework makes it possible to selectively examine comprehension, production, actions and their relation to visual attention in real-time. We demonstrate the utility of the framework through a proof-of-concept manipulating action structure, specifically path and manner, as well as other-initiated repair formats, namely open and restricted requests. The findings show that the setup reliably captures time-locked referential gaze dynamics following comprehension and preceding production processes. They further indicate that differences in action history systematically influence speakers’ pre-verbal cognitive processes and their subsequent linguistic choices. These findings suggest that HRI can provide a useful methodological middle ground to investigate language processes online in a tightly controlled setup without disrupting the interaction. More broadly, the framework offers a test bed for examining whether established psycholinguistic findings extend to HRI setups. At the same time, it provides HRI researchers with an empirical basis for developing adaptive agents informed by online language-vision interaction theories.}}, author = {{Singh, Amit and Rohlfing, Katharina J.}}, issn = {{0090-6905}}, journal = {{Journal of Psycholinguistic Research}}, number = {{5}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{A Methodological Framework for Studying Online Language–Vision Interplay in Human–Robot Interaction}}}, doi = {{10.1007/s10936-026-10296-z}}, volume = {{55}}, year = {{2026}}, } @inbook{66856, abstract = {{Abstract Goals are central to human actions: In fact, human actions are organized toward goals.

These needs are—according to Ainscow’s (2007) inclusive turn—not primarily ‘special educational needs’, but diverse needs of all learners. For the rather segregated German educational system, this endeavour applies especially to primary education, where needs are still developing and pupils are not yet assigned to different types of schooling according to their needs and abilities. Despite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine. The purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic. The overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots. The results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account.

By immobilizing the glycopeptide antibiotic vancomycin on DONs, DON binding to Gram‐positive and Gram‐negative bacteria can be facilitated. Here, we investigate how this multivalent binding is affected by the number and arrangement of the vancomycin modifications on two‐dimensional DONs. We find that for both Gram‐positive Bacillus subtilis and Gram‐negative Escherichia coli , binding increases with the number of vancomycin modifications per DON. In general, binding to E. coli is stronger than to B. subtilis , which may be attributed to differences in the architectures of the cell envelopes. Interestingly, for both bacteria, the total number of vancomycin modifications appears to be more important than their arrangement, as DONs with 18 vancomycin molecules on one side show similar binding as DONs with 18 vancomycin molecules distributed over both sides. This enables the attachment of multiple probe molecules to the vancomycin‐free side of the DONs for enhancing detection efficiency without compromising binding affinity. These results may thus provide guidelines for the design and synthesis of vancomycin‐modified DONs for antimicrobial drug delivery and pathogen detection. }}, author = {{Coşkuner Leineweber, Özge and Hofmann, Ulrike and Grundmeier, Guido and Zhang, Yixin and Keller, Adrian Clemens}}, issn = {{1439-4227}}, journal = {{ChemBioChem}}, number = {{13}}, publisher = {{Wiley}}, title = {{{Vancomycin‐Mediated Binding of DNA Origami Nanostructures to Gram‐Positive and Gram‐Negative Bacteria}}}, doi = {{10.1002/cbic.70436}}, volume = {{27}}, year = {{2026}}, } @misc{66079, author = {{Grauthoff, Fabian}}, booktitle = {{H-Soz-Kult}}, title = {{{Rezension zu: Bieker, Markus: Historische Perspektivität als kommunikatives Konstrukt.
