Digital tools can support focusing on meaningful tasks with features like time tracking, feedback, or rewards. Evidence exists for benefits regarding behavioral focus, distraction management, and motivation, but also for hesitation to use digital support at all. Building on the Unified Theory of Acceptance and Use of Technology (UTAUT), this research explores which factors can foster or hinder the intention to use an exemplary software to support self-regulation.\r\nMethods\r\nA sample of 96 adult volunteers watched a short introductory video explaining how the software focUS fosters self-regulated studying and working. Subsequently, participants completed an online survey to capture their willingness to use focUS, expected gains and challenges, and individual characteristics.\r\nResults\r\nParticipants expressed stronger intentions to use focUS when they expected increased benefits in performance. By trend, lower levels of expected effort also hinted on stronger intentions to use focUS. Contrary to expectations, participants lacking previous experience with software in the scope described, who anticipated higher effort when using focUS, tended to express stronger intentions to use it.\r\nDiscussion\r\nTaken together, our evidence suggests that highlighting specific performance improvements may encourage the use of digital support for tasks that require self-regulation. Ensuring the use of digital support to be as effortless as possible could provide yet another compelling argument to use it.

Therefore, this study investigated cortical and spinal excitability modulations during and following shortening of SSC contractions compared with pure shortening (SHO) contractions. Participants (n = 18) performed submaximal voluntary plantar flexion contractions while prone on the dynamometer bench. The right foot was strapped onto the dynamometer's footplate attachment, and the resultant ankle joint torque and crank arm angle were recorded. Cortical and spinal excitability modulations of the soleus muscle were analysed by eliciting compound muscle actional potentials via electrical nerve stimulation, cervicomedullary motor-evoked potentials (CMEPs) via electrical stimulation of the spinal cord, and motor-evoked potentials (MEPs) via magnetic stimulation of the motor cortex. Mean torque following stretch was significantly increased by 7 ± 3% (P = 0.029) compared with the fixed-end reference (REF) contraction, and mean torque during shortening of SSC compared with SHO was significantly increased by 12 ± 24% (P = 0.046). Mean steady-state torque was significantly lower by 13 ± 3% (P = 0.006) and 9 ± 12% (P = 0.011) following SSC compared with REF and SHO, respectively. Mean steady-state torque was not significantly different following SHO compared with REF (7 ± 8%, P = 0.456). CMEPs and MEPs were also not significantly different during shortening of SSC compared with SHO (P ≥ 0.885) or during the steady state of SSC, SHO and REF (P ≥ 0.727).

More recently, it has been suggested that cross-bridge (XB) kinetics and non-cross-bridge (non-XB) structures (e.g., titin and nebulin) contribute to the SSC-effect. As XBs and non-XB structures are characterized by a velocity dependence, we investigated the impact of stretch-shortening velocity on the SSC-effect. Accordingly, we performed in vitro isovelocity ramp experiments with varying ramp velocities (30, 60, and 85% of maximum contraction velocity for both stretch and shortening) and constant stretch-shortening magnitudes (17% of the optimum sarcomere length) using single skinned fibers of rat soleus muscles. The different contributions of XB and non-XB structures to force production were identified using the XB-inhibitor Blebbistatin. We show that (i) the SSC-effect is velocity-dependent\u2014since the power output increases with increasing SSC-velocity. (ii) The energy recovery (ratio of elastic energy storage and release in the SSC) is higher in the Blebbistatin condition compared with the control condition. The stored and released energy in the Blebbistatin condition can be explained by the viscoelastic properties of the non-XB structure titin. Consequently, our experimental findings suggest that the energy stored in titin during the eccentric phase contributes to the SSC-effect in a velocity-dependent manner.", "doi" : "https://doi.org/10.3389/fphys.2021.644981", "bibtexKey": "Tomalka_2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2cb291e05a1a3bbb91a404b35dfb148a0/tpollinger", "tags" : [ "{HPX}","myown","Performance","{CUDA}","Portability","hpc","Task-based","{GPU}","Kokkos" ], "intraHash" : "cb291e05a1a3bbb91a404b35dfb148a0", "interHash" : "23aeada47e005c4caa88b8ee189c767a", "label" : "Beyond Fork-Join: Integration of Performance Portable Kokkos Kernels with HPX", "user" : "tpollinger", "description" : "", "date" : "2022-03-24 16:12:08", "changeDate" : "2022-03-24 15:12:36", "count" : 3, "pub-type": "inproceedings", "booktitle": "2021 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW)", "year": "2021", "url": "", "author": [ "Gregor Daiß","Mikael Simberg","Auriane Reverdell","John Biddiscombe","Theresa Pollinger","Hartmut Kaiser","Dirk Pflüger" ], "authors": [ {"first" : "Gregor", "last" : "Daiß"}, {"first" : "Mikael", "last" : "Simberg"}, {"first" : "Auriane", "last" : "Reverdell"}, {"first" : "John", "last" : "Biddiscombe"}, {"first" : "Theresa", "last" : "Pollinger"}, {"first" : "Hartmut", "last" : "Kaiser"}, {"first" : "Dirk", "last" : "Pflüger"} ], "pages": "377--386","abstract": "Between a widening range of GPU vendors and the trend of having more GPUs per compute node in supercomputers such as Summit, Perlmutter, Frontier and Aurora, developing performant yet portable distributed HPC applications becomes ever more challenging. Leveraging existing solutions like Kokkos for platform-independent code and HPX for distributing the application in a task-based fashion can alleviate these challenges. However, using such frameworks in the same application requires them to work together seamlessly. In this work we present an HPX Kokkos integration that works both ways: we can integrate CPU and GPU Kokkos kernels as HPX tasks and inversely use HPX worker threads to work on Kokkos kernels. Using HPX futures makes launching and synchronizing Kokkos kernels from multiple threads easy, allowing us to move away from the more traditional fork-join model. To evaluate our integrations we ported existing Vc and CUDA kernels within an existing HPX application, Octo-Tiger, to use Kokkos instead. We achieve comparable, or better, performance than with previous Vc and CUDA kernels, showing both the viability of our HPX Kokkos integration, as well as future-proofing Octo-Tiger for a wider range of potential machines. Furthermore, we introduce event polling for synchronizing CUDA kernels (or Kokkos kernels on the respective backend) achieving speedups over the previous solution using callbacks.", "eventtitle" : "2021 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW)", "shorttitle" : "Beyond Fork-Join", "doi" : "10.1109/IPDPSW52791.2021.00066", "bibtexKey": "dais_beyond_2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/22107c5fc20a6011daa68f70fa4309d1d/mariawirzberger", "tags" : [ "myown","modeling","ACT-R","cognition","learning","performance" ], "intraHash" : "2107c5fc20a6011daa68f70fa4309d1d", "interHash" : "5f15226999856b02330804f9950fec55", "label" : "A model-based explanation of performance related changes in abstract stimulus-response learning", "user" : "mariawirzberger", "description" : "", "date" : "2020-03-20 16:22:37", "changeDate" : "2020-03-20 15:36:45", "count" : 1, "pub-type": "inproceedings", "booktitle": "52nd Annual Meeting of the Society for Mathematical Psychology.
