Anomalous Diffusion in Fractal Globules [PDF]

Physical Review Letters, 2015
The fractal globule state is a popular model for describing chromatin packing in eukaryotic nuclei. Here we provide a scaling theory and dissipative particle dynamics (DPD) computer simulation for the thermal motion of monomers in the fractal globule state. Simulations starting from different entanglement-free initial states show good convergence which

On the strong anomalous diffusion [PDF]

, 1998
The superdiffusion behavior, i.e. $ \sim t^{2 \nu}$, with $\nu > 1/2$, in general is not completely characherized by a unique exponent. We study some systems exhibiting strong anomalous diffusion, i.e. $ \sim t^{q \nu(q)}$ where $\nu(2)>1/2$ and $q \nu(q)

Diffusion tensor MRI phantom exhibits anomalous diffusion [PDF]

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
This paper reports diffusion weighted MRI measurements of cyclohexane in a novel diffusion tensor MRI phantom composed of hollow coaxial electrospun fibers (average diameter 10.2 μm). Recent studies of the phantom demonstrated its potential as a calibration standard at low b values (less than 1000 s/mm2) for mean diffusivity and fractional anisotropy ...

Anomalous diffusion-controlled evaporation [PDF]

Journal of the Chemical Society, Faraday Transactions 2, 1973
Diffusion-controlled, steady-state evaporation through certain membranes has been reported to proceed anomalously faster into a humid than into a dry atmosphere. The diffusion coefficient of such a membrane depends explicitly on both concentration and location within the membrane.

Characterizing anomalous diffusion in crowded polymer solutions and gels over five decades in time with variable-lengthscale fluorescence correlation spectroscopy [PDF]

, 2016
The diffusion of macromolecules in cells and in complex fluids is often found to deviate from simple Fickian diffusion. One explanation offered for this behavior is that molecular crowding renders diffusion anomalous, where the mean-squared displacement ...

Anomalous heat conduction and anomalous diffusion in nonlinear lattices, single walled nanotubes, and billiard gas channels

, 2004
We study anomalous heat conduction and anomalous diffusion in low dimensional systems ranging from nonlinear lattices, single walled carbon nanotubes, to billiard gas channels. We find that in all discussed systems, the anomalous heat conductivity can be

Measurement of Anomalous Diffusion Using Recurrent Neural Networks

, 2019
Anomalous diffusion occurs in many physical and biological phenomena, when the growth of the mean squared displacement (MSD) with time has an exponent different from one. We show that recurrent neural networks (RNN) can efficiently characterize anomalous

Anomalous Diffusion at Edge and Core of a Magnetized Cold Plasma

, 2009
Progress in the theory of anomalous diffusion in weakly turbulent cold magnetized plasmas is explained. Several proposed models advanced in the literature are discussed.

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
