This classification is based on the factorizability of homogeneous multivariate polynomials and is invariant under unitary transformations. The classes physically correspond to field excitations in terms of single and multiple photons, each of which being in an arbitrary irreducible superposition of quantized modes. We further show how the transitions between classes are rendered possible by photon addition, photon subtraction, and photon-projection nonlinearities. We explicitly put forward a design for a multilayer interferometer in which the states for different classes can be generated with state-of-the-art experimental techniques. Limitations of the proposed designs are analyzed using the introduced classification, providing a benchmark for the robustness of certain states and classes. }}, author = {{Kopylov, Denis and Offen, Christian and Ares, Laura and Wembe Moafo, Boris Edgar and Ober-Blöbaum, Sina and Meier, Torsten and Sharapova, Polina and Sperling, Jan}}, title = {{{Multiphoton, multimode state classification for nonlinear optical circuits }}}, year = {{2025}}, } @article{58238, abstract = {{Abstract Anterior cruciate ligament injuries (ACLi) impact football players substantially leading to performance declines and premature career endings. Emerging evidence suggests that ACLi should be viewed not merely as peripheral injuries but as complex conditions with neurophysiological aspects. The objective of the present study was to compare kicking performance and associated cortical activity between injured and healthy players. Ten reconstructed and 15 healthy players performed a kicking task. Kicking biomechanics were recorded using wearable inertial measurement unit sensors. Cortical activity was captured with a 64-electrode mobile electroencephalography. Multiscale entropy (MSE) analysis of biomechanics revealed increased variability in foot external rotation among injured players. Source-derived event-related spectral perturbations indicated significant differences in posterior alpha and frontal theta oscillations between the two groups. Furthermore, kick-related complexity of these regions as indexed by MSE was reduced in injured players at medium and coarse scales. Our findings suggest sensorimotor changes during kicking in injured players, which may necessitate compensatory strategies involving augmented attention at the cost of processing visuospatial information. This conflict may hinder the integration of task-relevant information across distributed networks. Our study provides preliminary insights into the neurophysiological implications of ACLi within football context and underscores the potential for prospective research.}}, author = {{Piskin, Daghan Yüksel and Cobani, Gjergji and Lehmann, Tim and Büchel, Daniel and Baumeister, Jochen}}, issn = {{2045-2322}}, journal = {{Scientific Reports}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Cortical changes associated with an anterior cruciate ligament injury may retrograde skilled kicking in football: preliminary EEG findings}}}, doi = {{10.1038/s41598-025-86196-4}}, volume = {{15}}, year = {{2025}}, } @article{58621, author = {{de Bruijn, Anne G.M. and Grimminger-Seidensticker, Elke}}, issn = {{0273-5024}}, journal = {{Journal of Teaching in Physical Education}}, pages = {{1--11}}, publisher = {{Human Kinetics}}, title = {{{Received and Perceived Peer Acceptance in Relation to Enjoyment, Social Competence, and Physical Activity in Primary School Physical Education and the Role of Peer-Relatedness Need Satisfaction}}}, doi = {{10.1123/jtpe.2024-0230}}, year = {{2025}}, } @article{58853, abstract = {{Abstract While being a promising approach for the treatment of infections caused by drug-resistant, pathogenic bacteria, the clinical implementation of phage therapy still faces several challenges. 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.

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{58907, author = {{Hörnlein, Madeleine}}, journal = {{die hochschullehre}}, title = {{{Physik lernen durch Erklären? - Evaluation eines Seminarkonzepts für Sachunterrichtsstudierende}}}, doi = {{https://dx.doi.org/10.3278/HSL2462W}}, volume = {{11}}, year = {{2025}}, } @inproceedings{58924, author = {{Peeters, Hendrik and Habig, Sebastian and Fechner, Sabine}}, booktitle = {{Actes des XIIIe Rencontres scientifiques de l’ARDIST}}, editor = {{Munier, Valérie and Bächtold, Manuel}}, location = {{Montpellier}}, pages = {{48--55}}, title = {{{Influence de l'utilisation de la réalité augmentée lors des expériences chimiques sur la connexion des niveaux de représentation dans les explications des élèves}}}, year = {{2025}}, } @article{58925, abstract = {{Abstract Random fluctuations in somatosensory signals affect the ability of effectively coordinating multimodal information pertaining to the postural state during movement. 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.

Previous research has not explored the combination of neurocognitive functions and motor demands through complex tasks for team ball sport athletes. The primary aim of the present study was to determine the construct validity of agility-based neurocognitive tests of working memory (WM) and inhibition. Methods: Twenty-seven athletes (5 females; mean age 24.2  [4.7] y; height 183.6 [9.1] cm; body mass 77.5 [11.2] kg) participated in the construct validity assessments that included computer-based tests (working memory capacity and stop-signal reaction time) and sport-specific assessments performed on the SpeedCourt system. Results: Construct validity analysis of sport-specific working memory yielded acceptable construct validity (r = .465, P < .05), whereas the sport-specific stop-signal task resulted in low construct validity (r = .179, P > .05). The poor construct validity results highlight the large variance between computer-based and sport-specific neurocognitive assessments. Conclusion: Sport-specific assessments are more complex and include more degrees of freedom potentially due to athletes’ center of mass displacement during task execution. These findings suggest that future research should focus more on the development of sport-specific assessments. These should include the cognitive and motor demands encountered during practice and competition, not use computer-based/pen and paper assessments for return to play decisions.}}, author = {{Gondwe, Benedict and Heuvelmans, Pieter and Benjaminse, Anne and Büchel, Daniel and Baumeister, Jochen and Gokeler, Alli}}, issn = {{1056-6716}}, journal = {{Journal of Sport Rehabilitation}}, pages = {{1--7}}, publisher = {{Human Kinetics}}, title = {{{Unveiling the Distinctions: Computer Versus Sport-Specific Neurocognitive Tests}}}, doi = {{10.1123/jsr.2024-0304}}, year = {{2025}}, } @article{58658, author = {{Webersen, Yvonne and Riese, Josef}}, journal = {{HLZ – Herausforderung Lehrer*innenbildung}}, number = {{1}}, title = {{{Umdenken!
