  abstract     = {{<jats:p>Clifford algebras are a natural extension of division algebras, including real numbers, complex numbers, quaternions, and octonions. Previous research in knowledge graph embeddings has focused exclusively on Clifford algebras of a specific type, which do not include nilpotent base vectors—elements that square to zero. In this work, we introduce a novel approach by incorporating nilpotent base vectors with a nilpotency index of two, leading to a more general form of Clifford algebras named degenerate Clifford algebras. This generalization to degenerate Clifford algebras does allow for covering dual numbers and as such include translations and rotations models under the same generalization paradigm for the first time. We develop two models to determine the parameters that define the algebra: one using a greedy search and another predicting the parameters based on neural network embeddings of the input knowledge graph. Our evaluation on seven benchmark datasets demonstrates that this incorporation of nilpotent vectors enhances the quality of embeddings. Additionally, our method outperforms state-of-the-art approaches in terms of generalization, particularly regarding the mean reciprocal rank achieved on validation data. Finally, we show that even a simple greedy search can effectively discover optimal or near-optimal parameters for the algebra.</jats:p>}},

  abstract     = {{We introduce a novel embedding method diverging from conventional approaches by operating within function spaces of finite dimension rather than finite vector space, thus departing significantly from standard knowledge graph embedding techniques. Initially employing polynomial functions to compute embeddings, we progress to more intricate representations using neural networks with varying layer complexities. We argue that employing functions for embedding computation enhances expressiveness and allows for more degrees of freedom, enabling operations such as composition, derivatives and primitive of entities representation. Additionally, we meticulously outline the step-by-step construction of our approach and provide code for reproducibility, thereby facilitating further exploration and application in the field.}},

  abstract     = {{This study analyzes whether and to what extent the provision of public goods and firms' trust in local governments' handling of local business tax revenues are associated with firms' willingness to pay local business tax. Using survey data on German small-and medium-sized firms, we find that the average perceived provision of public goods is not associated with the willingness to pay local business tax. Separating public goods into private-and business-related public goods, we find that the perception of public goods related to the private sphere of firms' decision-makers is associated with an increase in firms' willingness to pay local business tax by about 10%. However, public goods related to the business sphere show no similar association. Contradictory to the perceived provision of public goods, we find surprisingly no association between firms' willingness to pay local business tax and the actual provision of public goods. Trust in local governments' handling of tax revenue increases firms' willingness to pay local business tax significantly, with an effect size of about twice as large as for the perception of provided private-related public goods. These findings indicate that the handling of tax revenues exerts a more pronounced influence on firms' willingness to pay than the actual utilization of these revenues. Documenting tax revenue implications, we further show that the average willingness to pay local business tax within a local government is associated with a significant decrease in tax avoidance by about 10%. Our results inform local governments about how the provision of public goods and the building of trust can sustainably contribute to firms' willingness to pay local business tax. Thus, our results contribute to the understanding of how taxes can be efficiently collected and effectively used.}},

  abstract     = {{This study analyzes the impact of tax complexity on the location of tax employees and tax risk. Using a hand-collected dataset of more than 7,500 tax employees from 348 European-listed multinationals, we identify two types of firm-level costs associated with tax complexity—tax employees, and tax risk. We find that firms locate more tax employees in countries with greater tax complexity. This association is particularly pronounced for complexity in tax procedures. We also find that multinationals operating in countries with high tax complexity are associated with higher tax risk. The incremental tax risk vanishes for firms that locate more tax employees in countries with highly complex tax procedures, while we find no risk reduction from additional tax employees in countries with complex tax rules. Our results reveal that multinationals eliminate 25 percent of overall tax complexity-related tax risk through targeted location of tax employees.}},

  abstract     = {{Piezoelektrische Keramiken finden sowohl in Sensoren als auch in Aktoren Anwendung. Bei Hochleistungs-Ultraschallanwendungen sind diese Komponenten erheblichen elektrischen und mechanischen Belastungen ausgesetzt, was zum Auftreten nichtlinearer Effekte führt. Um das nichtlineare Materialverhalten piezoelektrischer Keramiken zu charakterisieren, kann eine statische mechanische Last aufgebracht werden, die den mechanischen Arbeitspunkt verschiebt. Durch Variation dieser statischen mechanischen Belastung kann das lineare Verhalten in jedem Betriebspunkt charakterisiert werden, woraufhin die nichtlinearen Eigenschaften des Materials angenähert werden können. Allerdings ist die Sicherstellung einer homogenen mechanischen Last anspruchsvoll. Alternativ kann eine hydrostatische Belastung realisiert werden, indem die Probe in einen Behälter gegeben wird, der mit unter Druck stehendem Fluid gefüllt ist. Dadurch wird eine gleichmäßige Lastverteilung über die Oberfläche der Probe erreicht.

In diesem Beitrag wird ein Versuchsaufbau zur Durchführung elektrischer Impedanzmessungen an piezoelektrischen Keramiken in einem Druckbehälter vorgestellt. Die Probe wird im Inneren des Druckbehälters elektrisch kontaktiert. Unter Verwendung von unter Druck stehendem Argon wird auf diese Weise die Messung der elektrischen Impedanz unter hydrostatischer Last von bis zu 200 bar ermöglicht. Anschließend wird ein inverses Verfahren angewendet, um die Materialparameter in Abhängigkeit von der aufgebrachten Last zu ermitteln.}},
