While the subjects perform continuous plantar- and dorsiflexion movements in two different controlled velocities, the ultrasound probe sweeps cyclically from the ankle to the knee along the anterior shin. The ankle joint angle can be determined using reflective motion capture markers. Since we considered the movement direction of the foot, i.e., active or passive TA, four conditions occur: slow active, slow passive, fast active, fast passive. By employing an algorithm which defines ankle joint angle intervals, i.e., intervals of range of motion (ROM), 3D images of the volumes during movement can be reconstructed.\r\n\r\nResults: We found constant muscle volumes between different muscle lengths, i.e., ROM intervals. The results show an increase in mean cross-sectional area (CSA) for TA muscle shortening. Furthermore, a shift in maximum CSA towards the proximal side of the muscle could be observed for muscle shortening. We found significantly different maximum CSA values between the fast active and all other conditions, which might be caused by higher muscle activation due to the faster velocity.\r\n\r\nConclusion: In summary, we present a method for determining muscle volume deformation during dynamic contraction using ultrasound, which will enable future empirical studies and 3D computational models of skeletal muscles.","annote":"","author":[],"citation-label":"siebert2024determination","collection-editor":[{"family":"Siebert","given":"Tobias"}],"collection-title":"","container-author":[{"family":"Siebert","given":"Tobias"}],"container-title":"Frontiers in Bioengineering and Biotechnology","documents":[],"edition":"","editor":[{"family":"Siebert","given":"Tobias"}],"event-date":{"date-parts":[["2024","June"]],"literal":"2024"},"event-place":"","id":"1947549f0f7295e064e79f467f085d7binspo5","interhash":"277676c63d8a348032cb6102b6abeb37","intrahash":"1947549f0f7295e064e79f467f085d7b","issue":"","issued":{"date-parts":[["2024","June"]],"literal":"2024"},"keyword":"3D contraction deformation dynamic image movement muscle processing ultrasound","misc":{"language":"English","doi":"10.3389/fbioe.2024.1388907"},"note":"","number":"","page":"","page-first":"","publisher":"","publisher-place":"","status":"","title":"Determination of muscle shape deformations of the tibialis anterior during dynamic contractions using 3D ultrasound.\r\nFront.

PMC5560678","URL":"https://doi.org/10.1371/journal.pone.0183204","abstract":"The punctum fixum-punctum mobile model has been introduced in previous publications. It describes general principles of intersegmental neuromuscular succession patterns to most efficiently generate specific movement intentions. The general hypothesis of this study is that these principles—if they really do indicate a fundamental basis for efficient movement generation—should also be found in intramuscular coordination and should be indicated by “longitudinal sequencing” between fibers according to the principles of the punctum fixum-punctum mobile model. Based on this general hypothesis an operationalized model was developed for the rectus femoris muscle (RF), to exemplarily scrutinize this hypothesis for the RF. Electromyography was performed for 14 healthy male participants by using two intramuscular fine wire electrodes in the RF (placed proximal and distal), three surface electrodes over the RF (placed proximal, middle, and distal), and two surface electrodes over the antagonists (m. biceps femoris and m. semitendinosus). Three movement tasks were measured: kicking movements; deceleration after sprints; and passively induced backward accelerations of the leg. The results suggest that proximal fibers can be activated independently from distal fibers within the RF. Further, it was shown that the hypothesized function of “intramuscular longitudinal sequencing” does exist during dynamic movements. According to the punctum fixum-punctum mobile model, the activation succession between fibers changes direction (from proximal to distal or inversely) depending on the intentional context. Thus, the results seem to support the general hypothesis for the RF and could be principally in line with the operationalized “inter-fiber to tendon interaction model”.","annote":"","author":[{"family":"von Laßberg","given":"Christoph"},{"family":"Schneid","given":"Julia A."},{"family":"Graf","given":"Dominik"},{"family":"Finger","given":"Felix"},{"family":"Rapp","given":"Walter"},{"family":"Stutzig","given":"Norman"}],"citation-label":"10.1371/journal.pone.0183204","collection-editor":[{"family":"Stutzig","given":"Norman"}],"collection-title":"","container-author":[{"family":"Stutzig","given":"Norman"}],"container-title":"PLOS ONE","documents":[],"edition":"","editor":[{"family":"Stutzig","given":"Norman"}],"event-date":{"date-parts":[["2017","08"]],"literal":"2017"},"event-place":"","id":"fd36e7e13c488bf8e769fe41bed60dc3inspo5","interhash":"9c585a2d480703d099c25ec697d427ed","intrahash":"fd36e7e13c488bf8e769fe41bed60dc3","issue":"8","issued":{"date-parts":[["2017","08"]],"literal":"2017"},"keyword":"Longitudinal dynamic femoris functions human intramuscular muscle rectus sequencing","misc":{"isbn":"PMID: 28817715","issn":"PMCID: PMC5560678","doi":"10.1371/journal.pone.0183204"},"note":"","number":"8","number-of-pages":"22","page":"1-23","page-first":"1","publisher":"Public Library of Science","publisher-place":"","status":"","title":"Longitudinal sequencing in intramuscular coordination: A new hypothesis of dynamic functions in the human rectus femoris muscle","type":"article-journal","username":"inspo5","version":"","volume":"12"},"08be7563b587190c24a78304dab29287mathematik":{"DOI":"https://doi.org/10.1016/j.jcp.2022.111031","ISBN":"","ISSN":"","URL":"https://www.sciencedirect.com/science/article/pii/S0021999122000936","abstract":"Multiphase flow in fractured porous media can be described\r\nby discrete fracture matrix models that represent the fractures as\r\ndimensionally reduced manifolds embedded in the bulk porous medium.\r\nGeneralizing earlier work on this approach we focus on immiscible\r\ntwo-phase flow in time-dependent fracture geometries, i.e., the fracture\r\nitself and the aperture of the fractures might evolve in time.

In this paper a new approach is proposed to the design of locally optimal controllers. It is iterative by nature, and starting from any initial feasible controller it performs local optimization over a suitably defined non-convex function at each iteration. The approach features the properties of computational efficiency, guaranteed convergence to a local optimum, and applicability to a very wide range of problems. Furthermore, a fast (but conservative) LMI-based procedure for computing an initially feasible controller is also presented.

In this paper a new approach is proposed to the design of locally optimal controllers. It is iterative by nature, and starting from any initial feasible controller it performs local optimization over a suitably defined non-convex function at each iteration. The approach features the properties of computational efficiency, guaranteed convergence to a local optimum, and applicability to a very wide range of problems. Furthermore, a fast (but conservative) LMI-based procedure for computing an initially feasible controller is also presented. The complete approach is demonstrated on a model of one joint of a real-life space robotic manipulator. (C) 2004 Elsevier Ltd.

Besides the physical development of a proof of concept demonstrator, the research proposes a digital form-driving process, a computational workflow which allows the design and fast simulation of the shape changing structure, as well as the digital control of the actuation on the component level. The proposed material system consists of an initially flat surface, which is tessellated into single components based on a hexagonal grid. Each cell is comprised of a three-layer system, where a pneumatic cushion is placed in the middle of two bending active plates with strategic cut outs [1]. In this way, each cell can be pneumatically actuated and therefore elastically deformed. The induced bending in the outer plates leads to a controlled change of area – the cells shrink or expand. By controlling this local behaviour within the global arrangement according to principle geometric rules [2] it is possible to achieve a controlled shape change from an initially flat surface to an anticlastic or synclastic geometric configuration. To design, simulate and control the shape change, the authors propose a digital form driving process. Here, the cells are abstracted and simplified into polygons, which can shrink and expand within a given range, according to the proposed physical system. This allows for the fast simulation of different actuation patterns and resulting geometric changes. The abstract values of shrinkage or expansion of each cell can be translated into pressure values and are used to control the pneumatic actuators in the physical demonstrator (figure 1).","annote":"","author":[{"family":"Mühlich","given":"Mona"},{"family":"Horvath","given":"David"},{"family":"Körner","given":"Axel"},{"family":"La Magna","given":"Riccardo"},{"family":"Knippers","given":"Jan"}],"citation-label":"muhlich2021curated","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Proceedings of the IASS Annual Symposium 2020/21","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2021"]],"literal":"2021"},"event-place":"","id":"1f5d6b34382ef9a1a751f224f2d0722aitke","interhash":"bd519dd915a8afc7f1ed728222450aaa","intrahash":"1f5d6b34382ef9a1a751f224f2d0722a","issue":"","issued":{"date-parts":[["2021"]],"literal":"2021"},"keyword":"architecture bending-active bionics change curated curvature deformation double dynamic elastic from:petraheim horvath itech itke knippers körner magna mühlich shape surfaces tesselated","misc":{"eventtitle":"IASS Annual Symposium 2020/21 and the 7th International Conference on Spatial Structures Inspiring the Next Generation","venue":"Guilford, UK","language":"eng","eventdate":"23 – 27 August 2021"},"note":"","number":"","page":"","page-first":"","publisher":"","publisher-place":"","status":"","title":"Curated deformation - dynamic shape change of tessellated surfaces","type":"paper-conference","username":"itke","version":"","volume":""}}
