Force plate coverings significantly affect measurement of ground reaction forces.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Nov 03; Vol. 18 (11), pp. e0293959. Date of Electronic Publication: 2023 Nov 03 (Print Publication: 2023).
Abstract: The purpose of this study was to carry out a material test to investigate the effect of different force plate coverings on vertical and horizontal ground reaction force and derived parameters. Four surface conditions were analysed; bare plate, vinyl, s...
Gravity alters muscle proteins.

Average current mode controller for bridgeless PFC SEPIC converter with second-order model reduction operated in continuous conduction mode.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Oct 17; Vol. 18 (10), pp. e0291873. Date of Electronic Publication: 2023 Oct 17 (Print Publication: 2023).
Abstract: This paper proposes an average current mode controller (ACMC) for a single-phase bridgeless power factor correction (PFC) circuit using a single ended primary inductor converter (SEPIC) via second-order model reduction. The superiority of the proposed ...
Methodological reflections on the MOND/dark matter debate.
Publication Type: Academic Journal
Source(s): Studies in history and philosophy of science [Stud Hist Philos Sci] 2023 Oct; Vol. 101, pp. 1-23. Date of Electronic Publication: 2023 Jul 31.
Abstract: The paper re-examines the principal methodological questions, arising in the debate over the cosmological standard model's postulate of Dark Matter vs. rivalling proposals that modify standard (Newtonian and general-relativistic) gravitational theory, ...
Newtonian gravitation in Maxwell spacetime.
Publication Type: Academic Journal
Source(s): Studies in history and philosophy of science [Stud Hist Philos Sci] 2023 Dec; Vol. 102, pp. 22-30. Date of Electronic Publication: 2023 Oct 03.
Abstract: This paper argues for the appropriateness of Maxwell spacetime as the minimal spacetime structure in which one may formulate a theory of Newtonian gravity. I begin by presenting an intrinsic characterization of Maxwell gravitation that, eschewing covar...
The psychophysics of bouncing: Perceptual constraints, physical constraints, animacy, and phenomenal causality.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Aug 18; Vol. 18 (8), pp. e0285448. Date of Electronic Publication: 2023 Aug 18 (Print Publication: 2023).
Abstract: In the present study we broadly explored the perception of physical and animated motion in bouncing-like scenarios through four experiments. In the first experiment, participants were asked to categorize bouncing-like displays as physical bounce, anima...
Test-retest reliability and sensitivity of senior elite amateur boxers maximal punch force, as quantified by a vertically mounted force plate.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Aug 10; Vol. 18 (8), pp. e0289791. Date of Electronic Publication: 2023 Aug 10 (Print Publication: 2023).
Abstract: An ecologically valid, reliable and sensitive method of quantifying punch force variables would be useful for coaches and practitioners monitoring combat-specific performance. The present study utilised a vertically mounted force plate to quantify the ...
Quantile regression for static panel data models with time-invariant regressors.
Publication Type: Academic Journal
Source(s): PloS one [PLoS One] 2023 Aug 02; Vol. 18 (8), pp. e0289474. Date of Electronic Publication: 2023 Aug 02 (Print Publication: 2023).
Abstract: This paper proposes two new weighted quantile regression estimators for static panel data model with time-invariant regressors. The two new estimators can improve the estimation of the coefficients with time-invariant regressors, which are computationa...
Spatio-temporal evolution of coupling coordination between new infrastructure and regional sustainability in China.
Publication Type: Academic Journal
Source(s): Environmental science and pollution research international [Environ Sci Pollut Res Int] 2023 Aug; Vol. 30 (40), pp. 91818-91838. Date of Electronic Publication: 2023 Jul 21.
Abstract: To achieve high-quality development, it is crucial to encourage the coordinated development of new infrastructure (NI) and regional sustainability (RS). Based on the coupling mechanism of NI and RS, this study develops a comprehensive evaluation index ...
Empty space and the (positive) cosmological constant.
Publication Type: Academic Journal
Source(s): Studies in history and philosophy of science [Stud Hist Philos Sci] 2023 Aug; Vol. 100, pp. 12-21. Date of Electronic Publication: 2023 Jun 08.
Abstract: I discuss empty space, as it appears in the physical foundations of relativistic field theories and in the semiclassical study of isolated systems. Of particular interest is the relationship between empirical measurements of the cosmological constant a...
