Local Law for Singular Values of Oscillatory Matrices

open access: yesInternational Mathematics Research Notices, 2021
AbstractWe continue the study of spectra of oscillatory random matrices with fully dependent rows. Motivated by the $d$-dimensional skew-shift dynamics from ergodic theory, we introduce the $N\times N$ random matrices $$ \begin{align*} &X_{j,k}=\exp\left(2\pi \textrm{i} \sum_{q=1}^d\ \omega_{j,q} k^q\right), \end{align*}$$where $\{\omega _{j,q}\}_ ...

Effect of Magnetic Field Dependent Viscosity on Darcy-Brinkman Ferroconvection with Second Sound

open access: yesEast European Journal of Physics, 2022
The problem of buoyancy-driven convection in a ferromagnetic fluid saturated porous medium with the Maxwell-Cattaneo law and MFD viscosity is investigated by the method of small perturbation. The fluid motion is described using the Brinkman model.

Large degree asymptotics of orthogonal polynomials with respect to an oscillatory weight on a bounded interval [PDF]

open access: yes, 2014
We consider polynomials p^w_n(x) that are orthogonal with respect to the oscillatory weight w(x)=exp(iwx) on [?1,1], where w>0 is a real parameter. A first analysis of p^?_n(x) for large values of w was carried out in connection with complex Gaussian ...

On second-order differential equations with highly oscillatory forcing terms [PDF]

open access: yes, 2010
We present a method to compute efficiently solutions of systems of ordinary differential equations that possess highly oscillatory forcing terms. This approach is based on asymptotic expansions in inverse powers of the oscillatory parameter,and features ...

Shear viscosity and nonlinear behaviour of whole blood under large amplitude oscillatory shear [PDF]

open access: yes, 2013
We investigated experimentally the rheological behavior of whole human blood subjected to large amplitude oscillatory shear under strain control to assess its nonlinear viscoelastic response.

The role of node dynamics in shaping emergent functional connectivity patterns in the brain

open access: yesNetwork Neuroscience, 2020
The contribution of structural connectivity to functional brain states remains poorly understood. We present a mathematical and computational study suited to assess the structure–function issue, treating a system of Jansen–Rit neural mass nodes with ...

Scale-up of oscillatory flow mixing [PDF]

open access: yes, 2011
Oscillatory Flow Mixing is a recent development in mixing technology which has evolved over the past decade. It has a number of similarities to other mixing technologies, particularly pulsed and reciprocating plate columns, but at the laboratory scale ...

Generalized reciprocity principle for discrete symplectic systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
This paper studies transformations for conjoined bases of symplectic difference systems $Y_{i+1}=\mathcal S_{i}Y_{i}$ with the symplectic coefficient matrices $\mathcal S_i.$ For an arbitrary symplectic transformation matrix $P_{i}$ we formulate most ...

Rheology of Emulsion-Filled Gels Applied to the Development of Food Materials

open access: yesGels, 2016
Emulsion-filled gels are classified as soft solid materials and are complex colloids formed by matrices of polymeric gels into which emulsion droplets are incorporated.

Asymptotic behavior and zero distribution of polynomials orthogonal with respect to Bessel functions [PDF]

open access: yes, 2015
We consider polynomials P_n orthogonal with respect to the weight J_? on [0,?), where J_? is the Bessel function of order ?. Asheim and Huybrechs considered these polynomials in connection with complex Gaussian quadrature for oscillatory integrals.
