Purpose: Develop a musculoskeletal-environment interaction model to reconstruct the dynamic-interaction process in skiing.
Methods: This study established a skier-ski-snow interaction (SSSI) model that integrated a 3D full-body musculoskeletal model, a flexible ski model, a ski boot model, a ski-snow contact model, and an air resistance model. An experimental method was developed to collect kinematic and kinetic data using IMUs, GPS, and plantar pressure measurement insoles, which were cost-effective and capable of capturing motion in large-scale field conditions.

The present protocol evaluates the relative impact of visual and vestibular inputs during roll plane rotations using optokinetic, vestibular, and combined visuovestibular stimulations. Subjects underwent isolated visual rotations, whole-body vestibular rotations in darkness, and visuovestibular stimulations combining static visual scenes with head rotations. Dynamic and static eye movement gains, absolute amplitudes, velocities, and accelerations were measured alongside perceptual responses.

In cluttered and complex natural scenes, selective attention enables the visual system to prioritize relevant information. This process is guided not only by perceptual cues but also by imagined ones. The current research extends the imagery-induced attentional bias to the unconscious level and reveals its cross-category applicability between different social cues (e.

We introduce a novel method using a kilohertz (kHz) amplified 800 nm laser for the first experimental confinement of microparticles within a single beam. This study demonstrates that high-energy kHz pulses can confine 1-μm-radius polystyrene beads in water within ∼26 μm. This approach utilizes the unique properties of high-energy pulsed lasers, distinct from continuous-wave and megahertz pulsed lasers traditionally used in optical trapping.

The dynamics of the different constituents of the ionic liquid 1-hexyl-3-methylimidazolium chloride (HmimCl) is investigated using nuclear magnetic resonance including chlorine relaxometry, line shape analysis, and proton-detected diffusometry, as well as frequency-dependent shear mechanical measurements. This combination of techniques is useful to probe the individual motions of the anions and the cations, and the sample's overall flow response. The 35Cl- dynamics appears to be close to the structural (or α-) relaxation as seen by rheology.
