In contrast, we suggest a different class of experiments in which the presence of a stronger trap is an essential part of the set-up. Because the trap-modified on-site energies exhibit a slowly varying level spacing, similar to that of an anharmonic oscillator, an additional time-periodic trap modulation with judiciously chosen parameters creates nonlinear resonances which enable efficient Floquet engineering. We employ a Mathieu approximation for constructing the near-resonant Floquet states in an accurate manner and demonstrate the emergence of effective ground states from the resonant trap eigenstates. Moreover, we show that the population of the Floquet states is strongly affected by the phase of a sudden turn-on of the trap modulation, which leads to significantly modified and rich dynamics. As a guideline for further studies, we argue that the deliberate population of only the resonance-induced effective ground states will allow one to realize Floquet condensates which follow classical periodic orbits, thus providing challenging future perspectives for the investigation of the quantum–classical correspondence.}}, author = {{Ali, Usman and Holthaus, Martin and Meier, Torsten}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, number = {{12}}, publisher = {{IOP Publishing}}, title = {{{Floquet dynamics of ultracold atoms in optical lattices with a parametrically modulated trapping potential}}}, doi = {{10.1088/1367-2630/ad9b47}}, volume = {{26}}, year = {{2024}}, } @inbook{57894, author = {{Große-Heilmann, Rike Isabel and Burde, Jan-Philipp and Riese, Josef and Schubatzky, Thomas and Weiler, David}}, booktitle = {{Lehrkräftebildung in der digitalen Welt - Zukunftsorientierte Forschungs- und Praxisperspektiven}}, editor = {{Herzig, Bardo and Eickelmann, Birgit and Schwabl, Franziska and Schulze, Johanna and Niemann, Jan}}, isbn = {{978-3-8309-4837-7}}, pages = {{135--150}}, publisher = {{Waxmann Verlag GmbH}}, title = {{{Entwicklung fachdidaktischen Wissens zum Einsatz digitaler Medien bei Lehramtsstudierenden im Fach Physik}}}, year = {{2024}}, } @inproceedings{57908, author = {{Jordans, Melanie and Riese, Josef}}, booktitle = {{Frühe naturwissenschaftliche Bildung.

This is achieved by incorporating different linker molecules (L) into the structure, generating isoreticular frameworks. CPO-27, also named MOF-74, is a prototypical material for this approach, offering the potential to modify the size of its one-dimensional pore channels and the hydrophobicity of pore walls using various linker ligands during synthesis. Thermal activation of these materials yields accessible open metal sites (i.e., under-coordinated metal centers) at the pore walls, thus acting as strong primary binding sites for guest molecules, including water. We study the effect of the pore size and linker hydrophobicity within a series of Ni2+-based isoreticular frameworks (i.e., Ni2L, L = dhtp, dhip, dondc, bpp, bpm, tpp), analyzing their water sorption behavior and the water interactions in the confined pore space. For this purpose, we apply water vapor sorption analysis and Fourier transform infrared spectroscopy. In addition, defect degrees of all compounds are determined by thermogravimetric analysis and solution 1H nuclear magnetic resonance spectroscopy. We find that larger defect degrees affect the preferential sorption sites in Ni2dhtp, while no such indication is found for the other materials in our study. Instead, strong evidence is found for the formation of water bridges/chains between coordinating water molecules, as previously observed for hydrophobic porous carbons and mesoporous silica. This suggests similar sorption energies for additional water molecules in materials with larger pore sizes after saturation of the primary binding sites, resulting in more bulk-like water arrangements.

The purpose was to investigate whether previous injuries associated with female soccer players’ interpersonal coordination during a collision avoidance task. The authors hypothesized that external perturbations would disrupt the strength and stability of coordinated movement, and that individuals with a history of injury would be less likely to recover coordinated movement. Study Design Cross-Sectional Methods Nine female athletes with a history of lower extremity injuries and nine without injuries were paired into dyads. Each dyad completed twenty trials of an externally paced collision-avoidance agility task with an unanticipated perturbation. Participant trajectories were digitized and analyzed using cross-recurrence quantification analysis (CRQA) to determine the strength and stability of interpersonal coordination dynamics. Trials in which participants with injury history assumed leader or follower roles within each dyad were then used to study how dyadic coordination varied across task stages (early, perturbation, and late) using linear mixed effect models. Cohen’s d effect sizes were calculated to demonstrate magnitude of differences. In exploratory analysis, psychological readiness (i.e., self-reported knee functioning, fear of injury, and risk-taking propensity) was evaluated for their association with leader-follower status. Results Perturbation disrupted the strength (R2=0.65, p<0.001, early=49.7±1.7, perturbation=41.1±1.7, d=0.39) and stability (R2=0.71, p < 0.001, early=65.0±1.6, perturbation=58.0±1.7, d=0.38) of interpersonal coordination regardless of leader-follower status. Individuals with injury history failed to restore coordination after the perturbation compared to control participants (injury=44.2.0±2.1, control=50.8±2.6, d=0.39). Neither demographic nor psychological measures were associated with leader-follower roles (B=0.039, p=0.224). Conclusion Individuals with a history of lower extremity injury may have a diminished ability to adapt interpersonal coordination to perturbations, possibly contributing to a higher risk of re-injury.

Setting Laboratory setting. Patients or Other Participants Sixteen individuals with ACLR and 18 uninjured controls. Main Outcome Measure(s) Normalized quadriceps isokinetic torque, hop distance, and respective limb symmetry indices were collected for each participant. Sagittal and frontal kinematics and kinetics of the trunk, hip, knee, and ankle as well as vertical and horizontal ground reaction forces were recorded for loading and propulsion of the take-off phase of the SLHD. Results Those with ACLR had weaker quadriceps peak torque in the involved limb (P = .001) and greater strength asymmetry (P &lt; .001) than control individuals. Normalized hop distance was not statistically different between limbs or between groups (P &gt; .05), and hop distance symmetry was not different between groups (P &gt; .05). During loading, the involved limb demonstrated lesser knee flexion angles (P = .030) and knee power (P = .007) than the uninvolved limb and lesser knee extension moments than the uninvolved limb (P = .001) and controls (P = .005). During propulsion, the involved limb demonstrated lesser knee extension moment (P = .027), knee power (P = .010), knee (P = .032) and ankle work (P = .032), and anterior-posterior ground reaction forces (P = .047) and greater knee (P = .016) abduction excursions than the uninvolved limb. Conclusions Between-limb differences in SLHD take-off suggest a knee underloading strategy in the involved limb. These results provide further evidence that distance covered during SLHD assessment can overestimate function and fail to identify compensatory biomechanical strategies. }}, author = {{Rush, Justin L. and Murray, Amanda M. and Sherman, David A. and Gokeler, Alli and Norte, Grant E.}}, issn = {{1938-162X}}, journal = {{Journal of Athletic Training}}, number = {{11}}, pages = {{1100--1109}}, publisher = {{Journal of Athletic Training/NATA}}, title = {{{Single-Leg Hop Performance After Anterior Cruciate Ligament Reconstruction: Ready for Landing but Cleared for Take-Off?}}}, doi = {{10.4085/1062-6050-0628.23}}, volume = {{59}}, year = {{2024}}, } @article{58700, abstract = {{AbstractPurposeThe study aimed to evaluate the impact of neurocognitive reliance on jump distance and lower extremity kinematics in individuals who had undergone anterior cruciate ligament reconstruction (ACLR).

Both groups performed a single‐leg hop for distance (SLHD) and two neurocognitive hop tests, each designed to evaluate distinct aspects of neurocognition. The neurocognitive tests included the reaction SLHD (R‐SLHD), measuring reaction to a central stimulus and working memory SLHD (WM‐SLHD) assessing response to a memorized stimulus amidst distractor stimuli. Distances were assessed for the three‐hop tests. In addition, joint kinematics were collected to calculate lower extremity coordination of the lower extremity. SLHD performance was defined as the mean hop distance per condition per leg for each participant and was analyzed using a mixed ANOVA with condition and leg as the within‐subjects factors and the group (ACLR or CTRL) as the between‐subjects factor. Differences in joint coordination variability were analyzed using two‐sample t‐test statistical parametric mapping (SPM) with linear regression.ResultsThe WM‐SLHD resulted in a significantly decreased jump distance compared with the standard hop test both for ACLR and CTRL. Furthermore, the leg difference within the ACLR group increased under higher cognitive load as tested with the WM‐SLHD, indicating leg‐specific adaptations in lower extremity coordination.ConclusionsNeurocognitive single‐leg hop tests resulted in reduced jump distance in CTRL and ACLR. The neurocognitive hop test revealed changes in coordination variability for the CTRL and the uninjured leg of ACLR individuals, whereas the injured leg's coordination variability remained unaltered, suggesting persistent cognitive control of movements post‐ACLR.Level of EvidenceLevel III.}}, author = {{Gokeler, Alli and Zandbergen, Marit A. and Hoogeslag, Roy A.

This is a promising concept to use in anterior cruciate ligament (ACL) injury prevention, as the key for risk reduction is to improve quality of movement. The goal of this study was to better understand why improved motor learning occurred when football players had the opportunity to choose when to receive feedback when practicing sidestep cutting (SSC) movements. Healthy male recreational football players (n = 22, 22.9 ± 1.7 years, 185.5 ± 7.2 cm, 79.3 ± 9.2 kg) were included and assigned to the self-control (SC) or the yoked (YK) group. The players performed anticipated and unanticipated SSC. They received video instructions and were instructed to “copy the movement of the model to the best of their ability.” During the training blocks, the SC group could ask for feedback, whereas the YK group could not. Cutting movement assessment scores (CMAS) were measured to test quality of movement and the Intrinsic Motivation Inventory was administered to measure constructs of motivation. In the anticipated condition, SC group showed better scores in immediate post and the retention test compared with pretest (p < 0.001), whereas the YK group showed worse scores in the retention test compared with immediate posttest (p = 0.001). Perceived competence (p = 0.017) and self-efficacy (p = 0.032) were consistent factors that correlated with improved CMAS in the SC group.

Purpose The purpose of this research was to study the effect of added cognitive load, in the form of increased visual attentional demands, on sidestep cutting kinematics during the energy absorption phase of the cut in an ecologically valid environment. Study Design Crossover Study Methods Fifteen male basketball players (aged 22.1 ± 2.3) performed ten sidestep cutting movements without (BASE) and with (VIS) a visual attention dual task. 3D kinematics of the hip, knee and ankle were recorded utilizing Xsens IMU motion capture. Temporal kinematics were analyzed using Statistical Parametric Mapping. Discrete time point kinematics were additionally analyzed at initial contact (IC) and at peak knee flexion utilizing paired t-tests. Effect sizes were calculated. Results Hip flexion was significantly reduced in the VIS condition compared to the BASE condition (p<0.01), including at IC (VIS 35.0° ± 7.2°, BASE 40.7° ± 4.9°, p=0.02, d=0.92) and peak (VIS 37.8° ± 9.7°, BASE 45.5° ± 6.9°, p=0.001, d=0.90).

Conclusion The addition of visual attention during sidestep cutting altered lower limb kinematics, which may increase ACL injury risk.
