Anomalous diffusion in silo drainage [PDF]
The European Physical Journal E, 2007 The silo discharge process is studied by molecular dynamics simulations. The development of the velocity profile and the probability density function for the displacements in the horizontal and vertical axis are obtained. The PDFs obtained at the beginning of the discharge reveal non-Gaussian statistics and superdiffusive behaviors. When the stationary

Difusão anômala e equações generalizadas de difusão
Revista Brasileira de Ensino de FísicaNeste trabalho apresentamos um conjunto de equações generalizadas de difusão que podem descrever processos difusivos anômalos. Não-linearidade, dependência espacial e temporal nos coeficientes da equação e derivadas fracionárias, bem como uma combinação ...

Fundamental solution of the model equation of anomalous diffusion of fractional order
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 Fundamental solution of the model equation of anomalous diffusion with Riemann-Liouville operator is constructed. Using the properties of the integral transformation with Wright function in kernel, we give estimates for the fundamental solution. When the

Time-space fabric underlying anomalous diffusion
, 2005 This study unveils the time-space transforms underlying anomalous diffusion process. Based on this finding, we present the two hypotheses concerning the effect of fractal time-space fabric on physical behaviors and accordingly derive fractional quantum ...

Anomalous diffusion in the dynamics of complex processes
, 2009 Anomalous diffusion, process in which the mean-squared displacement of system states is a non-linear function of time, is usually identified in real stochastic processes by comparing experimental and theoretical displacements at relatively small time ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Floquet Theory of Classical Relaxation in Time-Dependent Field
Mathematics, 2023 The anomalous transport of particles in the presence of a time-dependent field is considered in the framework of a comb model. This turbulent-like dynamics consists of inhomogeneous time-dependent advection along the x-backbone and Brownian motion along ...

Position and velocity space diffusion of test particles in stochastic electromagnetic fields
, 2007 The two--dimensional diffusive dynamics of test particles in a random electromagnetic field is studied. The synthetic electromagnetic fluctuations are generated through randomly placed magnetised ``clouds'' oscillating with a frequency $\omega$.
