A Simple Bayesian Method for the Analysis of Diffusion Processesdoi:10.2139/ssrn.111488This paper introduces a new Bayesian method for the analysis of discretely sampled diffusion processes. The method, which is termed high frequency augmentationSocial Science Electronic Publishing...
Some problems about the asymptotics of the first-passage time of a one-dimensional diffusion process through a stochastic, as well as deterministic one-sided boundary are studied, generalizing the analogous results found by Peskir and Shiryaev for Brownian motion.关键词: first-passage time stochastic...

A fundamental question is whether this tumultuous process has any predictable features which persist over long periods of time. Answering this question provides insights into the process of mixing which occurs in a whole range of systems, from the diffusion of dye into water, the dispersion of ...
Fair graph diffusion (Farnad et al. 2020) models and optimizes the propagation of information and influence over networks, and its probability of reaching individuals of different sensitive groups. Applications include obesity prevention (Antelope Valley Networks) and drug-use prevention (Homeless Youths...
The process is completed, the loop closed, when the diffusion of technology embodying the new idea, in turn, helps generate new creative ideas. Today there is evidence that the time between each of the steps in this cycle has been shortened.Thus it is not merely true, as frequently noted...
The Laplacian operator appears commonly in physics, most notably in the form of diffusion equations, such as the heat equation. Equations of the form 2 x = b are known as Poisson equations. The case where b = 0 is Laplace's equation, which is the origin of the Laplacian operator....
The process of turning a natural image into pure noise by adding successive noise to it is called the forward diffusion process, or forward process in short. Reverse process turns noise into a natural image On the other hand, we call the process of turning a Gaussian noise into a natu...
This paper addresses the study of a pillow lava interbedded with Late Albian-Early Cenomanian sediments that crops out in Armintza (Bizkaia, Northern Spain). The lava flow is an alkaline basalt with abundant macrocrysts of clinopyroxene, kaersutite, Ca-rich plagioclase (50-86% An) and ilmeni...
