Formula for permeability coefficient of coarse-grained soil based on parameters of two-dimensional fractal gradation model

Yantu gongcheng xuebao, 2023
The coarse-grained soil is widely distributed in nature and used in engineering. The permeability is one of its key properties, and for the same type of coarse-grained soil, its permeability is almost determined by the grain-size distribution and the ...

On the grain-sized distribution of turbulent dust growth

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT It has recently been shown that turbulence in the interstellar medium can significantly accelerate the growth of dust grains by accretion of molecules, but the turbulent gas density distribution also plays a crucial role in shaping the grain-sized distribution (GSD). The growth velocity, i.e. the rate of change of the mean grain

Impact of Age on the Diagnostic Yield of Routine EEG in People With Childhood or Juvenile Absence Epilepsy: A Cross‐Sectional Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background We aimed to identify the proportion of individuals with a confirmed diagnosis of childhood absence epilepsy (CAE) or juvenile absence epilepsy (JAE) who show a negative routine EEG (rEEG), and to determine the main factors associated with this finding.

Race and Household Income Are Associated With Disease Outcomes in Pediatric Patients With Antineutrophil Cytoplasmic Antibody–Associated Vasculitis Hospitalized in the United States

Arthritis Care &Research, EarlyView.
Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among

Employment Trajectories of Patients with Systemic lupus erythematosus (SLE) and Factors Driving Transitions Between States

Arthritis Care &Research, Accepted Article.
Objective Systemic lupus erythematosus (SLE) significantly impacts employment capacity. This study aimed to investigate the impact of burden of disease activity, damage, and treatment on employment outcomes and transitions in patients with SLE. Materials and Methods Using data from a single center, we analyzed employment transitions, adjusted mean ...

Estimation of Sediment Grain Size Distribution Using Optical Image-Based Spatial Feature Representation Learning with Data Augmentation

Journal of Marine Science and Engineering
This study introduces a spatial encoder network designed to estimate sand size distribution from optical images of sediments. The model achieves sufficient network capacity by stacking two-dimensional convolution-based encoder blocks to learn the spatial

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Sediment Grain Size Distribution under Quasi-Unsteady Flows through River Reaches [PDF]

Journal of Hydraulic and Water Engineering
This study explores the temporal and spatial dynamics of sediment transport and bed morphology under quasi-unsteady flow conditions, with an emphasis on the mean sediment grain size (d50). The experiments were conducted in an 18-meter-long, 1-meter-wide,
