Current model-based approaches offer possibilities to analyze and optimize tasks within an overall system, but they still lack integration. This leads to the research question: How can human factors be integrated into a system model of a socio-technical, Cyber-Physical Production System? The paper at hand contributes an approach of human factor integration into the procedure of Model-Based Systems Engineering for Cyber-Physical Production Systems (CPPS). The approach combines a system model of a CPPS with HSI concepts. In accordance to the benefits of MBSE, SysML is selected to integrate human factors in the development process of a CPPS. The approach is divided into five steps, which includes the extension of the SysML meta model. This allows the optimization of skill-based human-machine interaction. Defined HSI-Profiles enable system developers to integrate employee requirements at early stages within the development process. The approach is demonstrated by the maintenance of a 3D-Printer as a case example.

Besides conventional methods of inserting Trojans into a design by a malicious entity, the design flow for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised to assist the attacker to perform a successful malfunctioning or information leakage attack. The advanced stealthy malicious look-up-table (LUT) attack activates a Trojan only when generating the FPGA bitstream and can thus not be detected by register transfer and gate level testing and verification. However, also this attack was recently revealed by a bitstream-level proof-carrying hardware (PCH) approach. In this paper, we present a novel attack that leverages malicious routing of the inserted Trojan circuit to acquire a dormant state even in the generated and transmitted bitstream. The Trojan's payload is connected to primary inputs/outputs of the FPGA via a programmable interconnect point (PIP). The Trojan is detached from inputs/outputs during place-and-route and re-connected only when the FPGA is being programmed, thus activating the Trojan circuit without any need for a trigger logic. Since the Trojan is injected in a post-synthesis step and remains unconnected in the bitstream, the presented attack can currently neither be prevented by conventional testing and verification methods nor by recent bitstream-level verification techniques.}}, author = {{Ahmed, Qazi Arbab and Wiersema, Tobias and Platzner, Marco}}, booktitle = {{2021 Design, Automation & Test in Europe Conference & Exhibition (DATE)}}, location = {{Alpexpo | Grenoble, France}}, publisher = {{2021 Design, Automation and Test in Europe Conference (DATE)}}, title = {{{Malicious Routing: Circumventing Bitstream-level Verification for FPGAs}}}, doi = {{10.23919/DATE51398.2021.9474026}}, year = {{2021}}, } @misc{42989, author = {{Dewerth, Mats-Ole and Neukötter, Moritz}}, title = {{{Entwicklung eines Versuchsaufbaus zur rheo-optischen Untersuchung des Dehnverhaltens von Polymerschmelzen und -lösungen am Hochdruck-Kapillarrheometer (Studienarbeit)}}}, year = {{2021}}, } @misc{43004, author = {{Hütte, Marvin and Neukötter, Moritz}}, title = {{{Weiterentwicklung des Versuchsaufbaus zur Untersuchung von Polymerschmelzen und -lösungen am Hochdruck-Kapillarrheometer}}}, year = {{2021}}, } @article{23456, author = {{Mattiolo, Davide and Steffen, Eckhard}}, issn = {{0364-9024}}, journal = {{Journal of Graph Theory}}, keywords = {{factorization, perfect matchings, regular graphs, r-graphs}}, number = {{1}}, pages = {{107--116}}, title = {{{Highly edge‐connected regular graphs without large factorizable subgraphs}}}, doi = {{10.1002/jgt.22729}}, volume = {{99}}, year = {{2021}}, } @article{21827, author = {{Klopp, Antje and Steffen, Eckhard}}, issn = {{0911-0119}}, journal = {{Graphs and Combinatorics}}, pages = {{559--580}}, title = {{{Fractional Matchings, Component-Factors and Edge-Chromatic Critical Graphs}}}, doi = {{10.1007/s00373-020-02266-6}}, year = {{2021}}, } @article{13445, author = {{Steffen, Eckhard and Vogel, Alexander}}, journal = {{European J.

However, how and when to start a running program are uncertain. Objective To explore the feasibility of a structured program to reintroduce running after ACLR and evaluate the predictive value of potential predictors of short-term success. Design Longitudinal cohort study. Setting Local research center and participants' homes. Patients or Other Participants Thirty-five participants were recruited after ACLR. Intervention(s) Program with a progression algorithm to reintroduce running (10 running sessions in 14 days). Main Outcome Measure(s) The criterion for short-term success was no exacerbation of symptoms. Potential predictors were (1) the International Knee Documentation Committee (IKDC) subjective knee form score, (2) ACL Return to Sport after Injury questionnaire score, (3) quadriceps and hamstrings strength, (4) step-down endurance test, and (5) modified Star Excursion Balance test. Descriptive statistics were performed to study the feasibility of the RTR program, and Poisson regression analysis was used to evaluate predictors of success. Results Of the 34 participants, 33 completed the RTR program. Sixteen participants experienced some temporary exacerbation of symptoms, but only 1 had to stop the program. The initial IKDC score was the only significant predictor of a successful RTR, with an area under the receiver operating characteristic curve of 80.4%. An IKDC cut-off of 63.7/100 differentiated responders and nonresponders with the highest sensitivity and specificity (77.8% and 75.0%, respectively). A participant with an IKDC score above this threshold had a 3-fold greater chance of success. Conclusions Our results confirm the feasibility of our RTR program and progression algorithm after ACLR. Clinicians should use an IKDC score of >64 as a criterion to reintroduce running after ACLR to increase the likelihood of short-term success. }}, author = {{Pairot de Fontenay, Benoit and Van Cant, Joachim and Gokeler, Alli and Roy, Jean-Sébastien}}, issn = {{1938-162X}}, journal = {{Journal of Athletic Training}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine, General Medicine}}, number = {{6}}, pages = {{540--546}}, publisher = {{Journal of Athletic Training/NATA}}, title = {{{Reintroduction of Running After Anterior Cruciate Ligament Reconstruction With a Hamstrings Graft: Can We Predict Short-Term Success?}}}, doi = {{10.4085/1062-6050-0407.21}}, volume = {{57}}, year = {{2021}}, } @article{45135, abstract = {{Context: Only 55% of the athletes return to competitive sports after an anterior cruciate ligament (ACL) injury.

Current return-to-sports (RTS) tests utilize closed and predictable motor skills; however, demands on the field are different. Neurocognitive functions are essential to manage dynamic sport situations and may fluctuate after peripheral injuries. Most RTS and rehabilitation paradigms appear to lack this aspect, which might be linked to increased risk of second injury. Objective: This systematic and scoping review aims to map existing evidence about neurocognitive and neurophysiological functions in athletes, which could be linked to ACL injury in an integrated fashion and bring an extensive perspective to assessment and rehabilitation approaches. Data Sources: PubMed and Cochrane databases were searched to identify relevant studies published between 2005 and 2020 using the keywords ACL, brain, cortical, neuroplasticity, cognitive, cognition, neurocognition, and athletes. Study Selection: Studies investigating either neurocognitive or neurophysiological functions in athletes and linking these to ACL injury regardless of their design and technique were included. Study Design: Systematic review. Level of Evidence: Level 3. Data Extraction: The demographic, temporal, neurological, and behavioral data revealing possible injury-related aspects were extracted and summarized. Results: A total of 16 studies were included in this review. Deficits in different neurocognitive domains and changes in neurophysiological functions could be a predisposing risk factor for, or a consequence caused by, ACL injuries. Conclusion: Clinicians should view ACL injuries not only as a musculoskeletal but also as a neural lesion with neurocognitive and neurophysiological aspects. Rehabilitation and RTS paradigms should consider these changes for assessment and interventions after injury. }}, author = {{Piskin, Daghan and Benjaminse, Anne and Dimitrakis, Panagiotis and Gokeler, Alli}}, issn = {{1941-7381}}, journal = {{Sports Health: A Multidisciplinary Approach}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine}}, number = {{4}}, pages = {{549--555}}, publisher = {{SAGE Publications}}, title = {{{Neurocognitive and Neurophysiological Functions Related to ACL Injury: A Framework for Neurocognitive Approaches in Rehabilitation and Return-to-Sports Tests}}}, doi = {{10.1177/19417381211029265}}, volume = {{14}}, year = {{2021}}, } @article{45140, abstract = {{Background: Differential learning (DL) is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed (MEDLINE), Web of Science, and Google Scholar were searched until February 3, 2020. To be included, (1) studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method (lack of practice was not eligible), (2) studies had to describe the effects on one or more measures of performance in a skill or movement task, and (3) the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase (post-pre; I2 = 77%) as well as for the retention phase (retention-pre; I2 = 79%) was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found.}}, author = {{Tassignon, Bruno and Verschueren, Jo and Baeyens, Jean-Pierre and Benjaminse, Anne and Gokeler, Alli and Serrien, Ben and Clijsen, Ron}}, issn = {{1664-1078}}, journal = {{Frontiers in Psychology}}, keywords = {{General Psychology}}, publisher = {{Frontiers Media SA}}, title = {{{An Exploratory Meta-Analytic Review on the Empirical Evidence of Differential Learning as an Enhanced Motor Learning Method}}}, doi = {{10.3389/fpsyg.2021.533033}}, volume = {{12}}, year = {{2021}}, } @article{45138, abstract = {{Individuals after anterior cruciate ligament reconstruction (ACLR) have a high rate of reinjury upon return to competitive sports.

However, the non-isothermal nature of these processes leads to challenges in evaluating the forming limits, since established methods such as Forming Limit Curves (FLCs) only allow the assessment of critical forming strains for steady temperatures. For this reason, a temperature-dependent extension of the well-established GISSMO (Generalized Incremental Stress State Dependent Damage Model) fracture indicator framework is developed by the authors to predict forming failures under non-isothermal conditions. In this paper, a general approach to combine several isothermal FLCs within the temperature-extended GISSMO model into a temperature-dependent forming limit surface is investigated. The general capabilities of the model are tested in a coupled thermo-mechanical FEA using the example of warm forming of an AA5182-O sheet metal cross-die cup. The obtained results are then compared with state of the art of evaluation methods. By taking the strain and temperature path into account, GISSMO predicts greater drawing depths by up to 20% than established methods. In this way the forming and so the lightweight potential of sheet metal parts can by fully exploited. Moreover, the risk and locus of failure can be evaluated directly on the part geometry by a contour plot. An additional advantage of the GISSMO model is the applicability for low triaxialities as well as the possibility to predict the materials behavior beyond necking up to ductile fracture.}}, author = {{Camberg, Alan Adam and Erhart, Tobias and Tröster, Thomas}}, issn = {{1996-1944}}, journal = {{Materials}}, title = {{{A Generalized Stress State and Temperature Dependent Damage Indicator Framework for Ductile Failure Prediction in Heat-Assisted Forming Operations}}}, doi = {{10.3390/ma14175106}}, year = {{2021}}, } @misc{45254, author = {{Anonymous, Anonymous}}, title = {{{Device-Independent Security Proofs Via Entropy Accumulation}}}, year = {{2021}}, } @inbook{42253, author = {{Saad, Nadia}}, booktitle = {{Methoden der Darstellung und Analyse interreligiöser Diskurse}}, pages = {{354--355}}, publisher = {{Ergon Verlag}}, title = {{{David und Salomo im Koran: ein Komparativ-theologischer Ansatz}}}, volume = {{1}}, year = {{2021}}, } @article{42256, author = {{Mir Sadri, Seyedeh Saeideh and Nasiri, Mansour}}, journal = {{Philosophy East and West}}, number = {{2}}, pages = {{414--430}}, publisher = {{University of Hawai'i Press}}, title = {{{Reading Iqbal in the Light of Kierkegaard; towards an Existentialist Approach to Islam}}}, volume = {{71}}, year = {{2021}}, } @article{42257, author = {{Mir Sadri, Seyedeh Saeideh}}, journal = {{Amos-international}}, number = {{1}}, pages = {{27--35}}, title = {{{Fratelli e sorelle tutti.

Therefore, 316L specimens manufactured by laser powder bed fusion were examined in their as-built state as well as after grinding, or coating with regard to the surface roughness, residual stresses and LCF strength. To differentiate between topographical effects and residual stress-related phenomena, stress-relieved 316L specimens served as a reference throughout the investigations. To enable an alumina coating of the 316L components, atmospheric plasma spraying was used, and the near-surface residual stresses and the surface roughness are measured and investigated. Findings The results have shown that the applied pre- and post-treatments such as stress-relief heat treatment, grinding and alumina coating have each led to an increase in LCF strength of the 316L specimens. In contrast, the non-heat-treated specimens predominantly exhibited coating delamination.
