STEMDiff: A Wavelet‐Enhanced Diffusion Model for Physics‐Informed STEM Image Generation [PDF]

Advanced Science
Machine learning has emerged as a powerful tool for analyzing scanning transmission electron microscopy (STEM) images, yet its widespread application remains constrained by the scarcity of annotated training data.

A Hybrid Diffusion Model Enhances Multiparametric 3D Photoacoustic Computed Tomography [PDF]

Advanced Science
Photoacoustic computed tomography (PACT) reveals biological structures, pharmacokinetics, and physiological functions. Although a premium PACT system with many ultrasound (US) transducers delivers high‐quality volumetric imaging, it suffers from high ...

Diffusive majority-vote model [PDF]

Physical Review E, 2022
We define a stochastic reaction-diffusion process that describes a consensus formation in a non-sedentary population. The process is a diffusive version of the Majority Vote model, where the state update follows two stages: in the first stage, spins are allowed to hop to neighbor nodes with different probabilities for the respective spin orientation ...

Radar-SR3: A Weather Radar Image Super-Resolution Generation Model Based on SR3

Atmosphere, 2023
To solve the problems of the current deep learning radar extrapolation model consuming many resources and the final prediction result lacking details, a weather radar image super-resolution weather model based on SR3 (super-resolution via image ...

Recommendation model based on opinion diffusion [PDF]

, 2007
Information overload in the modern society calls for highly efficient recommendation algorithms. In this letter we present a novel diffusion based recommendation model, with users' ratings built into a transition matrix.

Fractional diffusion modeling of ion channel gating [PDF]

, 2004
An anomalous diffusion model for ion channel gating is put forward. This scheme is able to describe non-exponential, power-law like distributions of residence time intervals in several types of ion channels.

Exactly solvable model of quantum diffusion [PDF]

, 2004
We study the transport property of diffusion in a finite translationally invariant quantum subsystem described by a tight-binding Hamiltonian with a single energy band and interacting with its environment by a coupling in terms of correlation functions ...

Anomalous diffusion in a symbolic model [PDF]

, 2010
We address this work to investigate some statistical properties of symbolic sequences generated by a numerical procedure in which the symbols are repeated following a power law probability density.
