Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations. [PDF]
Magn Reson MedAbstract Purpose Rotational invariants (RIs) are at the root of many dMRI applications. Among others, they are presented as a sensible way of reducing the dimensionality of biophysical models. While thermal noise impact on diffusion metrics has been well studied, little is known on its effect on spherical harmonics‐based RI (RISH) features and derived ...

Can Any Stationary Iteration Using Linear Information Be Globally Convergent? [PDF]
, 1980 All known globally convergent iterations for the solution of a nonlinear operator equation f(x) = 0 are either nonstationary or use nonlinear information.

Laguerre and Hermite Collocation Methods for Unbounded Domains
East Asian Journal on Applied Mathematics, 2018 The authors discuss spectral collocation methods based on Jacobi-Gauss-Lobatto points and Laguerre and Hermite collocation for unbounded domains. These spectral collocation methods approximate derivatives by direct differentiation of Lagrange interpolation polynomials at Gauss-type points. The authors provide a new collocation scheme, where simulations

Laguerre and composite Legendre-Laguerre Dual-Petrov-Galerkin methods for third-order equations
Discrete & Continuous Dynamical Systems - B, 2006 Dual-Petrov-Galerkin approximations to linear third-order equations and the Korteweg-de Vries equation on semi-infinite intervals are considered. It is shown that by choosing appropriate trial and test basis functions the Dual-Petrov-Galerkin method using Laguerre functions leads to strongly coercive linear systems which are easily invertible and ...

Food Chemistry International, EarlyView.PBMA products were studied for their lipid stability, texture profiles and physicochemical properties under recommended refrigerated storage conditions. Lipid tests showed no indicators of lipid oxidation in the PBMA products after refrigerated storage; however, significant changes were observed in their textural and physicochemical properties ...

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate
Laser &Photonics Reviews, EarlyView.Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.
