DSMC simulation of the vertical structure of planetary rings [PDF]

Astronomy & Astrophysics, 2001
A statistical Monte Carlo method (DSMC) is developed to simulate granular flows occurring in dense planetary rings. The accuracy of the method is assessed through a comparison with existing molecular dynamics simulations of the vertical structure of planetary rings with and without self-gravity eects.

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1798-1820, July/August 2026.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Modeling and Design of ANFIS Dynamic Sliding Mode Controller for a Knee Orthosis of Hemiplegia

Applied Bionics and Biomechanics, 2023
The use of assistive devices to control the loss of strength and range of motion of hemiplegic patients is becoming common. It is difficult to develop a precise control approach for a knee orthosis system because of the unpredictability of the dynamics ...

Clinical, Radiological, and Immunohistological Distinctions Between Limbic‐Predominant and Typical Alzheimer's Disease: A Systematic Review

Brain and Behavior, Volume 16, Issue 7, July 2026.
Abstract Background Alzheimer's disease (AD) is the most common cause of dementia worldwide and one of the leading causes of morbidity and mortality among elderly people. It is characterized by generalized brain atrophy, especially affecting the hippocampus and medial temporal lobe.

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

DSMC: A Novel Distributed Store-Retrieve Approach of Internet Data Using MapReduce Model and Community Detection in Big Data

International Journal of Distributed Sensor Networks, 2014
The processing of big data is a hotspot in the scientific research. Data on the Internet is very large and also very important for the scientific researchers, so the capture and store of Internet data is a priority among priorities.

Fatty Liver Index Shows Poor Discrimination for MRI‐Measured Hepatic Steatosis in African Compared with European Adults

Liver International Communications, Volume 7, Issue 2, June 2026.
ABSTRACT Background and Aim The Fatty Liver Index (FLI) is a proxy for hepatic steatosis, but its performance against magnetic resonance imaging (MRI) is unknown in African populations. We evaluated the discriminatory performance of the FLI for detecting hepatic steatosis in European men (EM) and West African men (WAM) in the UK, and Black South ...

Gas Flow and Heat Transfer in an Enclosure Induced by a Sinusoidal Temperature

Journal of Applied Fluid Mechanics, 2019
The heat transfer and flow characteristics of rarefied gas confined within a square cavity are investigated. The cavity upper-wall is subjected to a symmetrical sinusoidal temperature with respect to its midline.

Bayesian estimation-based information exchange techniques for coupled Navier-Stokes equation and DSMC algorithms

Kongqi donglixue xuebao
In the calculation process of coupled Navier-Stokes (N-S) equation and direct simulation Monte Carlo (DSMC) algorithms, the DSMC method suffers from a limited number of statistical samples.

Spatial Surface Mass Flux on Confined Fibers: DSMC Validation of a Kinetic‐Theory Model for Forced‐Flow CVI Deposition

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Chemical vapor infiltration (CVI) is widely used to manufacture ceramic matrix composites, but deposition non‐uniformity and premature pore closure still limit processing time and cost. CVI operates at low pressures and in microscale pores, where non‐equilibrium gas transport develops, making common continuum assumptions unreliable.
