Fluctuations Driven by Multicomponent Pickup Ion Distributions in the Outer Heliosheath
Published 2025-01-01“…Two-dimensional (2D) simulation results show that when all unstable waves are present, the predominant contributor to the fluctuating magnetic field energy is the AC mode. The AC waves quickly scatter the PUIs with pitch angles away from 90 ^∘ toward isotropy, while the PUIs near 90 ^∘ pitch angle maintain a degree of anisotropy within our simulation timeframe. …”

Brain plasticity associated with prolonged shooting training: a multimodal neuroimaging investigation from a cross-sectional study
Published 2025-02-01“…BackgroundAlthough training has been recognized as a potential contributor to neuroplasticity in athletes, the impact of prolonged shooting training on human brain plasticity remains unclear in the existing literature.MethodsIn this cross-sectional study, we used a multimodal neuroimaging analysis, including the analysis of functional blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) images, structural T1-weighted MRI images, and diffusion MRI images, to systematically identify differences between elite shooters and normal controls.ResultsThe results showed that compared to male normal controls, male elite shooters had higher regional homogeneity (ReHo) in the frontal lobe, parietal lobe, precuneus, thalamus, and cingulate gyrus, as well as higher functional connectivity between the medial frontal cortex (MedFC) and temporooccipital middle temporal gyrus (toMTG). …”
