Diffusing Diffusivity: A Model for Anomalous, yet Brownian, Diffusion [PDF]

Physical Review Letters, 2014
Wang et al. [Proc. Natl. Acad. Sci. U.S.A. 106, 15160 (2009)] have found that in several systems the linear time dependence of the mean-square displacement (MSD) of diffusing colloidal particles, typical of normal diffusion, is accompanied by a non-Gaussian displacement distribution G(x,t), with roughly exponential tails at short times, a situation ...

A Diffusion Approximation for an Epidemic Model [PDF]

, 2006
Influenza is one of the most common and severe diseases worldwide. Devastating epidemics actuated by a new subtype of the influenza A virus occur again and again with the most important example given by the Spanish Flu in 1918/19 with more than 27 ...

A Noise-Robust Blind Deblurring Algorithm With Wavelet-Enhanced Diffusion Model for Optical Remote Sensing Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Blind deblurring of optical remote sensing images has been a longstanding challenge. In recent years, many learning-based deblurring algorithms have been greatly developed.

Fluctuations and scaling in models for particle aggregation

, 2005
We consider two sequential models of deposition and aggregation for particles. The first model (No Diffusion) simulates surface diffusion through a deterministic capture area, while the second (Sequential Diffusion) allows the atoms to diffuse up to \ell

Random diffusion model

Physical Review E, 2008
We study here the random diffusion model. This is a continuum model for a conserved scalar density field $ $ driven by diffusive dynamics. The interesting feature of the dynamics is that the {\it bare} diffusion coefficient $D$ is density dependent. In the simplest case $D=\bar{D}+D_{1} $ where $\bar{D}$ is the constant average diffusion constant ...

Testing the drift-diffusion model [PDF]

Proceedings of the National Academy of Sciences, 2020
SignificanceThe drift-diffusion model (DDM) has been widely used in psychology and neuroeconomics to explain observed patterns of choices and response times. This paper provides an identification and characterization theorems for this model: We show that the parameters are uniquely pinned down and determine which datasets are consistent with some form ...

Prompt Conditioned Batik Pattern Generation Using LoRA Weighted Diffusion Model With Classifier-Free Guidance

IEEE Access
Batik, a significant element of Indonesian cultural heritage, is renowned for its intricate patterns and profound philosophical meanings. While preserving traditional batik is crucial, the creation of modern patterns is equally encouraged to keep the art

A Reduced-Order Model of Heat Transfer Effects on the Dynamics of Bubbles [PDF]

, 2002
The Rayleigh-Plesset equation has been used extensively to model spherical bubble dynamics, yet it has been shown that it cannot correctly capture damping effects due to mass and thermal diffusion.
