One of these challenges lies in the high strain-specificity of most bacteriophages, which makes it necessary to screen large phage collections against the target pathogens in order to identify suitable candidates for the formulations of personalized therapeutic phage cocktails. In this work, we evaluate the potential of quartz crystal microbalance with dissipation monitoring (QCM-D) to identify and detect phage infection and subsequent lysis of bacteria immobilized on the surfaces of the QCM-D sensors. Using lytic Escherichia coli phage T7 as a model, we show that phage infection of E. coli cells results in various unique alterations in the behaviors of the frequency (Δf) and dissipation (ΔD) signals, which are not observed during exposure of the E. coli strain to non-infectious Bacillus subtilis phage phi29 at similar concentration. To aid future phage screening campaigns, we furthermore identify a single measurement parameter, i.e., the spread between the different overtones of ΔD, that can be used to detect phage-induced lysis. For T7 infection of E. coli, this is achieved within 4 h after inoculation, including immobilization and growth of the bacteria on the sensor surface, as well as the completed phage propagation cycle. Given the commercial availability of highly automated multichannel systems and the fact that this approach does not require any sensor modifications, QCM-D has the potential to become a valuable tool for screening medium-sized phage collections against target pathogens.

We prove a local-global principle relating the distribution of extensions over global function fields to their distribution over local fields, leading to an asymptotic formula for the number of extensions with a given global last-jump invariant. A key ingredient is Abrashkin's nilpotent Artin-Schreier theory, which lets us parametrize extensions and obtain bounds on the ramification of local extensions by estimating the number of solutions to certain polynomial equations over finite fields.}}, author = {{Gundlach, Fabian and Seguin, Beranger Fabrice}}, booktitle = {{arXiv:2502.18207}}, title = {{{Counting two-step nilpotent wildly ramified extensions of function fields}}}, year = {{2025}}, } @inproceedings{58869, author = {{Meier, Jana and Meusel, Sarah}}, location = {{Universität zu Köln}}, title = {{{Zusammenhänge zwischen dem Rollenverständnis angehender Lehrpersonen und ihren Einstellungen zu Mehrsprachigkeit}}}, year = {{2025}}, } @article{58556, abstract = {{To predict and prevent uneven tire wear in addition to a reduction of overall tire wear, it is essential to estimate not only the total amount of wear but also how the wear is distributed across the tire width. This requires knowledge of the frictional power distribution in the tire contact patch, which is the basis for calculating tire wear using a wear law. Usually, only 3D structural tire models can generate such distributed contact results. However, they involve high computational costs and cannot be used for comprehensive optimization of a vehicle’s suspension system with respect to tire wear characteristics. Hence, this contribution presents a methodology on how to accelerate the prediction of the frictional power distribution using two components: The structural tire model is replaced by an empirical tire model that on its own is not able to generate distributed contact results. Therefore, an artificial neural network is trained to predict the desired contact results from the kinematic quantities calculated by the empirical tire model. In the initial training phase, both components are fitted to data generated by the original complex tire model. After training, the empirical tire model can replace the structural tire model in vehicle simulations, resulting in significantly shorter calculation times. The simulation results are fed into the artificial neural network, which predicts the frictional power distributions over the tire width with negligible additional effort. Overall, the methodology reduces calculation time for the prediction of tire wear based on virtual test drives to approximately 25% of the time needed when using structural tire models.}}, author = {{Muth, Lars and Zharia, Raphael and Sahin, Hürkan and Sextro, Walter}}, journal = {{Tire Science and Technology}}, publisher = {{The Tire Society}}, title = {{{Prediction of the Frictional Power Distribution in the Tire Contact Patch Based on an Empirical Tire Model and an Artificial Neural Network}}}, doi = {{https://doi.org/10.2346/TST-24-009}}, year = {{2025}}, } @article{58165, author = {{Neumann, Maximilian and Xia, Marc and Pöschmann, René and Merkel, Amelie and Staud, Rolf and Schneider, Hannes and Ehlert, Thomas and Paschold, Jürgen and Müller, Steffen and Harding, Laura-Selin and Neukäufer, Johannes and Hiller, Christoph and Ausner, Ilja and Gäbler, Ansor and Chromik, Reiner and Maćkowiak, Jan and Maćkowiak, Jerzy and Sola Cervera, Jose Luis and Geipel, Christian and Brinkmann, Jost and Bausa, Jürgen and Zeck, Sebastian and Hapke, Mark and Forner, Florian and Habla, Florian and Knaup, Manuel and Schulz, Robin and Schultes, Michael and Harlacher, Thomas and Lutters, Nicole and Kenig, Eugeny and Jasch, Katharina and Paschetag, Mandy and Scholl, Stephan and Grünewald, Marcus and Brösigke, Georg and Repke, Jens-Uwe and Klein, Harald and Rehfeldt, Sebastian}}, issn = {{1383-5866}}, journal = {{Separation and Purification Technology}}, publisher = {{Elsevier BV}}, title = {{{Towards reliable HETP values: Lessons learned from standardized separation efficiency measurements}}}, doi = {{10.1016/j.seppur.2025.131436}}, volume = {{361}}, year = {{2025}}, } @unpublished{58872, abstract = {{Given a non-compact semisimple real Lie group $G$ and an Anosov subgroup $\Gamma$, we utilize the correspondence between $\mathbb R$-valued additive characters on Levi subgroups $L$ of $G$ and $\mathbb R$-affine homogeneous line bundles over $G/L$ to systematically construct families of non-empty domains of proper discontinuity for the $\Gamma$-action.

A recent and popular model is the Refined Consensus Model (RCM), which proposes a framework of dispositional competencies (personal PCK—pPCK) that influence more action-related competencies (enacted PCK—ePCK) and vice versa. However, descriptions of the internal structure of pPCK and possible knowledge domains that might develop independently are still limited, being either primarily theoretically motivated or strictly hierarchical and therefore of limited use, for example, for formative feedback and further development of the RCM. Meanwhile, a non-hierarchical differentiation for the ePCK regarding the plan-teach-reflect cycle has emerged. In this study, we present an exploratory computational approach to investigate pre-service teachers' pPCK for a similar non-hierarchical structure using a large dataset of responses to a pPCK questionnaire (N=846). We drew on theoretical foundations and previous empirical findings to achieve interpretability by integrating this external knowledge into our analyses using the Computational Grounded Theory (CGT) framework. The results of a cluster analysis of the pPCK scores indicate the emergence of prototypical groups, which we refer to as competency profiles: (1) a group with low performance, (2) a group with relatively advanced competency in using pPCK to create instructional elements, (3) a group with relatively advanced competency in using pPCK to assess and analyze described instructional elements, and (4) a group with high performance. These groups show tendencies for certain language usage, which we analyze using a structural topic model in a CGT-inspired pattern refinement step. We verify these patterns by demonstrating the ability of a machine learning model to predict the competency profile assignments. Finally, we discuss some implications of the results for the further development of the RCM and their potential usability for an automated formative assessment.}}, author = {{Zeller, Jannis and Riese, Josef}}, issn = {{1098-2736}}, journal = {{Journal of Research in Science Teaching}}, keywords = {{computational grounded theory, language analysis, machine learning, pedagogical content knowledge, unsupervised learning}}, title = {{{Competency Profiles of PCK Using Unsupervised Learning: What Implications for the Structures of pPCK Emerge From Non-Hierarchical Analyses?}}}, doi = {{10.1002/tea.70001}}, year = {{2025}}, } @article{56641, author = {{Diller, Markus and Lorenz, Johannes and Schneider, Georg and Sureth-Sloane, Caren}}, journal = {{The Accounting Review}}, number = {{2}}, pages = {{71 -- 102}}, title = {{{Is Tax Transfer Pricing Harmonization a Panacea?

Therefore, this study aimed to investigate the impact of a compliant surface on cortico-cortical causal information flow during multi-joint compound movements. Fifteen healthy adults (7 female / 8 male, 25.9 ± 4.0 years) performed 5 × 20 repetitions of bodyweight squats on firm and compliant surface. Motor behavior was quantified by center of pressure (CoP) displacements, hip movement and the root mean square of the rectus femoris activity. Using source space analysis, renormalized partial directed coherence (rPDC) computed subject-level multivariate effective brain connectivity of sensorimotor nodes. Bootstrap statistics revealed significantly decreased medio-lateral CoP displacement (p < 0.001), significantly increased velocity of medio-lateral hip motion (p < 0.001) as well as significantly lower rectus femoris activity (p < 0.01) in the compliant surface condition. On the cortical level, rPDC showed significantly modulated information flow in theta and beta frequencies for fronto-parietal edges (p < 0.01) only during the concentric phase of the movement. The compliant surface led to increased difficulties controlling hip but not center of pressure motion in the medio-lateral plane. Moreover, a decreased activation of the prime movers accompanied by modulations of effective brain connectivity among fronto-central nodes may point to altered demands on sensorimotor information processing in presence of sensory noise when performing bodyweight squats on compliant surface. Further studies are needed to evaluate a potential benefit for athletic and clinical populations.}}, author = {{Lehmann, Tim and Visser, Anton Samuel and Havers, Tim and Büchel, Daniel and Baumeister, Jochen}}, issn = {{0014-4819}}, journal = {{Experimental Brain Research}}, number = {{4}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Dynamic modulations of effective brain connectivity associated with postural instability during multi-joint compound movement on compliant surface}}}, doi = {{10.1007/s00221-025-07039-2}}, volume = {{243}}, year = {{2025}}, } @inbook{58691, author = {{Albus, Vanessa}}, booktitle = {{Nachhaltigkeit in der Medienkommunikation.
