Diffusion, Self-Diffusion and Cross-Diffusion

open access: yesJournal 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 ...

Diffusing Diffusivity: A Model for Anomalous, yet Brownian, Diffusion [PDF]

open access: yesPhysical 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 ...

Mediación editorial y valor agregado: La obra de Jaime Saenz desde las redes sociales del pasado

open access: yesBolivian 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

Interpolation process between standard diffusion and fractional diffusion [PDF]

open access: yes, 2017
We consider a Hamiltonian lattice field model with two conserved quantities, energy and volume, perturbed by stochastic noise preserving the two previous quantities.

Interlacing Diffusions [PDF]

open access: yes, 2019
We study in some generality intertwinings between $h$-transforms of Karlin-McGregor semigroups associated with one dimensional diffusion processes and those of their Siegmund duals. We obtain couplings so that the corresponding processes are interlaced and furthermore give formulae in terms of block determinants for the transition densities of these ...

Truncated correlation photoacoustic coherence tomography: An axial resolution enhancement imaging modality

open access: yesPhotoacoustics, 2021
In this report we present a novel photoacoustic (PA) modality using pulsed chirp excitation at a fixed wavelength and spectral analysis based on frequency-domain (FD) processing.

Diffusing diffusivity: Rotational diffusion in two and three dimensions [PDF]

open access: yesThe 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

MICRA: an automatic pipeline for fast characterization of microbial genomes from high-throughput sequencing data

open access: yesGenome Biology, 2017
The increase in available sequence data has advanced the field of microbiology; however, making sense of these data without bioinformatics skills is still problematic.

The quantification and correction of wind-induced precipitation measurement errors [PDF]

open access: yesHydrology 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
