Efficient prediction of aerodynamic forces in rarefied flow using convolutional neural network based multi-process method

Machine Learning: Science and Technology
The direct simulation Monte Carlo (DSMC) is a widely used approach for studying aerodynamics effects of rarefied flows, but it is highly time-consuming and may exhibit statistical fluctuations.

Visualization of Molecular Transport by the DSMC Method

Journal of the Visualization Society of Japan, 1996
Rarefied gas flows through the circular tubes with a finite length were numerically simulated by the Direct Simulation of Monte Carlo method. The effects of boundary conditions, such as accommodation coefficients and surface temperatures at the solid surfaces of the tubes are discussed.

Plasma biomarkers are related to white matter integrity in alzheimer's disease continuum

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Plasma biomarkers (PB) of Alzheimer's disease (AD) is a non‐invasive and economic alternative for early diagnosis. Due to the increasing incidence of dementia worldwide, understanding the relationship between PB and other AD biomarkers, such as neuroimaging is necessary.

Computer simulations of an impurity in a granular gas under planar Couette flow

, 2011
We present in this work results from numerical solutions, obtained by means of the direct simulation Monte Carlo (DSMC) method, of the Boltzmann and Boltzmann--Lorentz equations for an impurity immersed in a granular gas under planar Couette flow.

Correlation Between Functional Connectivity in the Default Mode Network (DMN) and Plasma Biomarker Concentrations in Patients with Mild Cognitive Impairment

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background Disruptions in brain network connectivity are strongly associated with the progression of cognitive decline in the Alzheimer's disease (AD) continuum, including mild cognitive impairment (MCI). This study aimed to investigate the relationship between alterations in functional brain connectivity within the default mode network (DMN ...

An Investigation of Cognitive Performance and Electroencephalographic Correlations in a Healthy Elderly Sample

Alzheimer's &Dementia, Volume 21, Issue S3, December 2025.
Abstract Background With the growth of the elderly population and the increasing incidence of diseases related to cognitive decline, there is a growing demand for effective cognitive screening methods. This study explores the application of a memory and learning test integrated with electroencephalographic (EEG) monitoring in healthy elderly ...
