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 ...

Diffusing diffusivity: Rotational diffusion in two and three dimensions [PDF]
The Journal of Chemical Physics, 2017 We consider the problem of calculating the probability distribution function (pdf) of angular displacement for rotational diffusion in a crowded, rearranging medium. We use the diffusing diffusivity model and following our previous work on translational diffusion [R. Jain and K. L. Sebastian, J. Phys. Chem. B 120, 3988 (2016)], we show that the problem

Diffusion, Self-Diffusion and Cross-Diffusion
Journal of Differential Equations, 1996 The following system, which determines steady-state solutions for a corresponding parabolic system, is considered: \[ \begin{aligned} \Delta[(d_1+\alpha_{11}u_1+\alpha_{12}u_2)u_1] &+u_1(a_1-b_1u_1-c_1u_2)=0,\\ \Delta[(d_2+\alpha_{21}u_1+\alpha_{22}u_2)u_2] &+u_2(a_2-b_2u_1-c_2u_2)=0\quad\text{in }\Omega,\end{aligned} \] \[ {\partial u_1\over\partial ...

Ukrainian Mathematical Journal, 2020 In the present paper, we give a series of definitions and properties of Lifting Dynamical Systems (LDS) corresponding to the notion of deterministic diffusion. We present heuristic explanations of the mechanism of formation of deterministic diffusion in LDS and the anomalous deterministic diffusion in the case of transportation in long billiard ...

Mediación editorial y valor agregado: La obra de Jaime Saenz desde las redes sociales del pasado
Bolivian Studies Journal, 2021 Una mirada crítica al lugar que ocupa Jaime Saenz en el panorama de la traducción de literaturas extranjeras podría clarificar la construcción de su imagen de escritor tanto en Bolivia como en los países en los que se lo ha traducido. ¿Cómo se ve la obra

The quantification and correction of wind-induced precipitation measurement errors [PDF]
Hydrology and Earth System Sciences, 2017 Hydrologic measurements are important for both the short- and long-term management of water resources. Of the terms in the hydrologic budget, precipitation is typically the most important input; however, measurements of precipitation are subject to large

Diffusion, super-diffusion and coalescence from single step [PDF]
, 2007 From the exact single step evolution equation of the two-point correlation function of a particle distribution subjected to a stochastic displacement field $\bu(\bx)$, we derive different dynamical regimes when $\bu(\bx)$ is iterated to build a velocity ...
