Thin Fe/Cr films with lateral composition gradients were deposited by magnetron sputtering; the analysis of the films was done with microscopy and X-ray photoelectron spectroscopy (XPS). The local interfacial polymeric film formation could be therefore directly correlated with the Fe:Cr ratio. The local thickness and structure of the formed polycarbonate residue was analyzed by means of imaging ellipsometry, atomic force microscopy as well as Fourier-transform infrared spectroscopy under grazing incidence and XPS. Moreover, confocal fluorescence microscopy of the PC melt/alloy interface could reveal the formation of minor degradation products in the interphase region. The results show that already an Fe:Cr ratio of 2 : 1 leads to a strong inhibition of the thermal degradation in comparison to the unalloyed iron, and that in general, the enrichment of chromium in the passive film leads to an effective suppression of interfacial PC degradation. The data contributes to improving the mechanistic understanding of the role of iron during this process. Additionally, a critical concentration of chromium in the alloys used for PC processing can be deduced.}}, author = {{Theile-Rasche, Chantal and Meng, T. and de los Arcos de Pedro, Maria Teresa and Grundmeier, Guido}}, issn = {{2523-3971}}, journal = {{SN Applied Sciences}}, number = {{10}}, pages = {{1–12}}, title = {{{Analysis of polycarbonate degradation at melt/FeCr-alloy interfaces as a function of the alloy composition by means of combinatorial thin film chemistry}}}, doi = {{10.1007/s42452-023-05441-5}}, volume = {{5}}, year = {{2023}}, } @article{58609, abstract = {{Plasma Processes and Polymers is a plasma journal focusing on the interdisciplinary field of low temperature plasma science.}}, author = {{de los Arcos de Pedro, Maria Teresa and Awakowicz, Peter and Böke, Marc and Boysen, Nils and Brinkmann, Ralf Peter and Dahlmann, Rainer and Devi, Anjana and Eremin, Denis and Franke, Jonas and Gergs, Tobias and Jenderny, Jonathan and Kemaneci, Efe and Kühne, Thomas D. and Kusmierz, Simon and Mussenbrock, Thomas and Rubner, Jens and Trieschmann, Jan and Wessling, Matthias and Xie, Xiaofan and Zanders, David and Zysk, Frederik and Grundmeier, Guido}}, issn = {{1612-8850}}, journal = {{PLASMA PROCESSES AND POLYMERS}}, pages = {{e2300186}}, title = {{{PECVD and PEALD on polymer substrates (part II): Understanding and tuning of barrier and membrane properties of thin films}}}, doi = {{10.1002/ppap.202300186}}, year = {{2023}}, } @article{58610, author = {{de los Arcos de Pedro, Maria Teresa and Awakowicz, Peter and Benedikt, Jan and Biskup, Beatrix and Böke, Marc and Boysen, Nils and Buschhaus, Rahel and Dahlmann, Rainer and Devi, Anjana and Gergs, Tobias and Jenderny, Jonathan and von Keudell, Achim and Kühne, Thomas D. and Kusmierz, Simon and Müller, Hendrik and Mussenbrock, Thomas and Trieschmann, Jan and Zanders, David and Zysk, Frederik and Grundmeier, Guido}}, issn = {{1612-8850}}, journal = {{PLASMA PROCESSES AND POLYMERS}}, pages = {{e2300150}}, title = {{{PECVD and PEALD on polymer substrates (part I): Fundamentals and analysis of plasma activation and thin film growth}}}, doi = {{10.1002/ppap.202300150}}, year = {{2023}}, } @article{58607, author = {{Xie, Xiaofan and Zanders, David and Preischel, Florian and de los Arcos de Pedro, Maria Teresa and Devi, Anjana and Grundmeier, Guido}}, issn = {{0142-2421}}, journal = {{Surface and Interface Analysis}}, title = {{{Complementary spectroscopic and electrochemical analysis of the sealing of micropores in hexamethyldisilazane plasma polymer films by Al 2 O 3 atomic layer deposition}}}, doi = {{10.1002/sia.7256}}, year = {{2023}}, } @inbook{58619, author = {{Dehn, Freya}}, booktitle = {{Berufsbildender Deutschunterricht im Kontext von Migration und Einwanderung}}, editor = {{Becker, Karina and Kofer, Martina}}, pages = {{193--208}}, publisher = {{Waxmann}}, title = {{{Das Lesen von Fachtexten in der beruflichen Schule der Migrationsgesellschaft.

Für die zweite Wandler-Stufe hat sich in den vergangenen Jahren ein LLC-Resonanzwandler qualifiziert, der die Ladeleistung an die Traktionsbatterie galvanisch getrennt überträgt. Der Zwischenkreis besteht aus einer Bank von Elektrolytkondensatoren, in denen die pulsierende Eingangsleistung zwischengespeichert wird.

Research has been conducted in laboratory settings, but the contribution of neurocognition to actual ACL injuries under real-world conditions is unknown. Objective To describe the possible neurocognitive errors involved in noncontact ACL injury mechanisms. Design Case series. Setting Soccer matches. Patients or Other Participants A total of 47 professional male soccer players. Main Outcome Measure(s) Three independent reviewers evaluated 47 videos of players sustaining noncontact ACL injuries. Neurocognitive errors in inhibitory control were operationalized as follows: (1) motor-response inhibition was scored when a player demonstrated poor decision-making and approached the opponent with high speed that reduced the ability to stop or change the intended action and (2) an attentional error was scored when a player shifted his selective attention away from the relevant task to irrelevant stimuli. Results Of 47 noncontact ACL injuries, 26 (55%) were related to a pressing-type injury, 19 (73%) of which involved a deceiving action made by the opponent, suggesting poor inhibitory control of the defender. Of the remaining 21 noncontact ACL injuries (45%), 16 (76%) could be attributed to attentional errors. Agreement among the 3 raters was very good for all items except poor decision-making, which showed fair to good agreement (Fleiss κ = 0.71). Interrater reliability was excellent (intraclass correlation coefficient = 0.99–1.00). Conclusions Errors in motor-response inhibitory control and attentional inhibition were common during noncontact ACL injury events in professional male soccer players. The interrater agreement in detecting neurocognitive errors in general was very good. }}, author = {{Gokeler, Alli and Tosarelli, Filippo and Buckthorpe, Matthew and Della Villa, Francesco}}, issn = {{1938-162X}}, journal = {{Journal of Athletic Training}}, number = {{3}}, pages = {{262--269}}, publisher = {{Journal of Athletic Training/NATA}}, title = {{{Neurocognitive Errors and Noncontact Anterior Cruciate Ligament Injuries in Professional Male Soccer Players}}}, doi = {{10.4085/1062-6050-0209.22}}, volume = {{59}}, year = {{2023}}, } @article{58703, abstract = {{ Individual performance in team sports is a multifactorial reflection of how well a player can cope and accomplish tasks in varied playing situations. Thus, performance analysis should not only focus on outcomes, but also on underlying mechanisms of those outcomes. We adopted principles of the ecological dynamics approach (EDA) to investigate the effect of introducing constraints on players’ joint coordination responses for a football-specific performance drill outcome. Seventeen talented youth football (soccer) players performed a football-specific drill under different conditions: basic constraints, additional defender dummies, stroboscopic glasses, and a combination of the latter two constraints. We recorded these players’ execution time, passing accuracy, and lower extremity joint kinematics. We calculated joint coordination for hip-knee, knee-ankle, and trunk-hip couplings. The added constraints negatively affected execution time and passing accuracy, and caused changes in joint coordination. Furthermore, we identified a relationship between execution time and joint coordination. This study serves as an example how the EDA can be adopted to investigate mechanisms that underlie individual performance in team sports. }}, author = {{Heuvelmans, Pieter and Di Paolo, Stefano and Benjaminse, Anne and Bragonzoni, Laura and Gokeler, Alli}}, issn = {{0031-5125}}, journal = {{Perceptual and Motor Skills}}, number = {{1}}, pages = {{161--176}}, publisher = {{SAGE Publications}}, title = {{{Relationships Between Task Constraints, Visual Constraints, Joint Coordination and Football-Specific Performance in Talented Youth Athletes: An Ecological Dynamics Approach}}}, doi = {{10.1177/00315125231213124}}, volume = {{131}}, year = {{2023}}, } @article{58718, abstract = {{Variation during practice is widely accepted to be advantageous for motor learning and is, therefore, a valuable strategy to effectively reduce high-risk landing mechanics and prevent primary anterior cruciate ligament (ACL) injury. Few attempts have examined the specific effects of variable training in athletes who have undergone ACL reconstruction. Thereby, it is still unclear to what extent the variations in different sensor areas lead to different effects. Accordingly, we compared the effects of versatile movement variations (DL) with variations of movements with emphasis on disrupting visual information (VMT) in athletes who had undergone ACL reconstruction. Forty-five interceptive sports athletes after ACL reconstruction were randomly allocated to a DL group (n = 15), VT group (n = 15), or control group (n = 15). The primary outcome was functional performance (Triple Hop Test). The secondary outcomes included dynamic balance (Star Excursion Balance Test (SEBT)), biomechanics during single-leg drop-landing task hip flexion (HF), knee flexion (KF), ankle dorsiflexion (AD), knee valgus (KV), and vertical ground reaction force (VGRF), and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)) assessed before and after the 8 weeks of interventions. Data were analyzed by means of 3 × 2 repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of p ≤ 0.05. Significant group × time interaction effects, main effect of time, and main effect of group were found for the triple hop test and all eight directions, SEBT, HF, KF, AD, KV, VGRF, and TSK. There was no significant main effect of group in the HF and triple hop test. Additionally, significant differences in the triple hop test and the seven directions of SEBT, HF, KF, KV, VGRF, and TSK were found between the control group and the DL and VMT groups. Between group differences in AD and the medial direction of SEBT were not significant. Additionally, there were no significant differences between VMT and the control group in the triple hop test and HF variables.

In particular, we propose a multitask approach that jointly learns to generate both the conclusion and the counter of an input argument. The approach employs a stance-based ranking component that selects the counter from a diverse set of generated candidates whose stance best opposes the generated conclusion. In both automatic and manual evaluation, we provide evidence that our approach generates more relevant and stance-adhering counters than strong baselines.}}, author = {{Alshomary, Milad and Wachsmuth, Henning}}, booktitle = {{Proceedings of the 17th Conference of the European Chapter of the Association for Computational Linguistics}}, editor = {{Vlachos, Andreas and Augenstein, Isabelle}}, pages = {{957–967}}, publisher = {{Association for Computational Linguistics}}, title = {{{Conclusion-based Counter-Argument Generation}}}, doi = {{10.18653/v1/2023.eacl-main.67}}, year = {{2023}}, } @article{58717, author = {{Nijmeijer, Eline M. and Heuvelmans, Pieter and Bolt, Ruben and Gokeler, Alli and Otten, Egbert and Benjaminse, Anne}}, issn = {{0021-9290}}, journal = {{Journal of Biomechanics}}, publisher = {{Elsevier BV}}, title = {{{Concurrent validation of the Xsens IMU system of lower-body kinematics in jump-landing and change-of-direction tasks}}}, doi = {{10.1016/j.jbiomech.2023.111637}}, volume = {{154}}, year = {{2023}}, } @inproceedings{45775, abstract = {{RISC-V has received worldwide acceptance in the industry and by the academic community.
