Stochastic modeling in nanoscale biophysics: Subdiffusion within proteins [PDF]

open access: yes, 2008
Advances in nanotechnology have allowed scientists to study biological processes on an unprecedented nanoscale molecule-by-molecule basis, opening the door to addressing many important biological problems. A phenomenon observed in recent nanoscale single-

Quasi-periodic pulse amplitude modulation in the accreting millisecond pulsar IGR J00291+5934

open access: yes, 2017
We introduce a new method for analysing the aperiodic variability of coherent pulsations in accreting millisecond X-ray pulsars. Our method involves applying a complex frequency correction to the time-domain light curve, allowing for the aperiodic ...

Sorting photons by radial quantum number [PDF]

open access: yes, 2017
The Laguerre-Gaussian (LG) modes constitute a complete basis set for representing the transverse structure of a {paraxial} photon field in free space. Earlier workers have shown how to construct a device for sorting a photon according to its azimuthal LG

Uncoupled continuous-time random walks: Solution and limiting behavior of the master equation

open access: yes, 2004
A detailed study is presented for a large class of uncoupled continuous-time random walks (CTRWs). The master equation is solved for the Mittag-Leffler survival probability.

A lysing polysaccharide monooxygenase from effectively facilitated rumen microbial fermentation of rice straw [PDF]

open access: yesAnimal Bioscience
Objective This study investigated the impact of Aspergillus niger lysing polysaccharide monooxygenase (AnLPMO) on in vitro rumen microbial fermentation of rice straw. Methods AnLPMO was heterologously expressed in Escherichia coli.

Fractional dynamics of systems with long-range interaction

open access: yes, 2011
We consider one-dimensional chain of coupled linear and nonlinear oscillators with long-range power wise interaction defined by a term proportional to 1/|n-m|^{\alpha+1}.

Explicit Hermite-type eigenvectors of the discrete Fourier transform [PDF]

open access: yes, 2015
The search for a canonical set of eigenvectors of the discrete Fourier transform has been ongoing for more than three decades. The goal is to find an orthogonal basis of eigenvectors which would approximate Hermite functions -- the eigenfunctions of the ...

On the solvability of a space-time fractional nonlinear Schrödinger system

open access: yesPartial Differential Equations in Applied Mathematics
This paper is devoted to the theoretical analysis of a coupled nonlinear system of fractional Schrödinger equations in Rn×R+, n≥1, considering time fractional derivative in the Caputo sense, and a fractional spatial dispersion defined in terms of the ...

Fractional Dynamics of Systems with Long-Range Space Interaction and Temporal Memory

open access: yes, 2007
Field equations with time and coordinates derivatives of noninteger order are derived from stationary action principle for the cases of power-law memory function and long-range interaction in systems.

Focusing Algorithm of Range Profile for Plasma-Sheath-Enveloped Target

open access: yesRemote Sensing
In this paper, a one-dimensional (1-D) range profile of the hypersonic target enveloped by a plasma sheath is investigated. Firstly, the non-uniform property of the plasma sheath is studied and its impact on the wideband electromagnetic (EM) wave is ...
