Nonlinear guiding center (NLGC) theory has been used to explain the asymptotic perpendicular diffusion coefficient κ⊥ of energetic charged particles in a turbulent magnetic field, which can be applied better understand cosmic ray transport. Here we re-derive NLGC, replacing assumption diffusive decorrelation with random ballistic (RBD), yields an explicit formula for κ⊥. We note that scattering processes cause reversal motion along field line, i.e., "backtracking," leading partial...
We study the enhancement of accuracy high-order lattice Boltzmann method (LBM) in both order equilibrium-distribution expansion and degree precision Gauss–Hermite quadrature. Furthermore, we investigate regularization. utilize two-dimensional Kolmogorov flow Taylor–Green vortex over a wide range Knudsen numbers (Kn) as benchmark. The quadrature is assessed up to 33, 14, regularization 10. compare results direct simulation Monte Carlo (DSMC) method. indicate an improvement from increasing but...
Recognizing movements during sleep is crucial for the monitoring of patients with disorders, and utilization ultra-wideband (UWB) radar classification human postures has not been explored widely. This study investigates performance an off-the-shelf single antenna UWB in a novel application postural transition (SPT) recognition. The proposed Multi-View Learning, entitled SleepPoseNet or SPN, time series data augmentation aims to classify four standard SPTs. SPN exhibits ability capture both...
In the past few years, there are several researches on Parkinson's disease (PD) recognition using single-photon emission computed tomography (SPECT) images with deep learning (DL) approach. However, DL model's complexity usually results in difficultmodel interpretation when used clinical. Even though multiple methods available for model, is no evidence of which method suitable PD application. This tutorial aims to demonstrate procedure choose a interpretationmethod recogni-tion model. We...
This work theoretically determined the high-energy photon shielding properties of high-density polyethylene (HDPE) composites containing rare-earth oxides, namely samarium oxide (Sm2O3), europium (Eu2O3), and gadolinium (Gd2O3), for potential use as lead-free X-ray-shielding gamma-shielding materials using XCOM software package. The considered were mass attenuation coefficient (µm), linear (µ), half value layer (HVL), lead equivalence (Pbeq) that investigated at varying energies (0.001–5...
This work assessed the theoretical neutron-shielding capabilities of autonomously self-healing poly(vinyl alcohol) (PVA) hydrogels containing rare-earth oxides, namely samarium oxide (Sm2O3), europium (Eu2O3), and gadolinium (Gd2O3), through PHITS GEANT4 simulations. The assessment covered a range filler contents (from 0 to 20 %wt in 4 increments) neutron energies (0.025 eV, 1 MeV, MeV). determination showed that there was good agreement between results from both simulations (average...
This work numerically determined high-energy photon shielding properties of self-healing poly(vinyl alcohol) (PVA) hydrogels containing lead-free, heavy-metal compounds, namely, bismuth oxide (Bi2O3), tungsten (WO3), and barium sulfate (BaSO4), through XCOM software packages. In order to understand the dependencies on filler contents energies, added were varied from 0–40 wt.% energies 0.001–5 MeV. The results, which verified for their reliability correctness with those obtained PHITS...
In this work, the 1D-3V particle simulation with Monte Carlo collision and cumulative scattering angle Coulomb was developed to study kinetic behavior of detached plasma. The constant pressure temperature neutral gas box in front divertor target were used simulation. performed a fixed upstream plasma density nu ∼ 3 × 1018 m−3 modified large frequency. When is increased, there strong decrease electron inside box. also decreases below 1 eV, which one conditions for
This work reports on the simulated neutron and self-emitted gamma attenuation of ultra-high-molecular-weight polyethylene (UHMWPE) composites containing varying Sm2O3 contents in range 0–50 wt.%, using a simulation code, namely MCNP-PHITS. The energy investigated was 0.025 eV (thermal neutrons), energies were 0.334, 0.712, 0.737 MeV. results indicated that abilities to attenuate thermal neutrons rays noticeably enhanced with addition Sm2O3, as seen by increases µm µ, decrease HVL. By...
Abstract This research numerically studies the formation of a detached plasma and energy loss processes during hydrogen (H) gas puffing by using 1D-3 V Particle-In-Cell (PIC) code. In this study, PIC with Monte Carlo Collision (MCC) cumulative scattering angle Coulomb collision has been developed for investigating kinetic behavior plasma. The density increases near target plate increasing neutral pressure. flow velocity, ion temperature, electron temperature are reduced toward when is...

During 2D magnetic reconnection, plasma is normally understood to flow from one of the inflow sides into diffusion region and then turn sharply join outflow on same side. Using particle-in-cell simulations with a modification allow us label ions electrons by their initial locations, we find that inflowing does not side; instead, crosses other side before changing direction produce an jet. Furthermore, undergo different crossover mechanisms leading crossing patterns. The ion occurs more...
