Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations [PDF]
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 204-219, January 2026.Abstract 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 ...

About the Production of the Continuous X-Ray Spectrum [PDF]
Proc Natl Acad Sci U S A, 1929 I propose, therefore, to generalize my previous assumption so as to admit secondary beams to emerge from the scattering atom in all directions. This amounts to an averaging of the matrix elements defined in my former note over all possible directions ...

COMPOSITE LAGUERRE PSEUDOSPECTRAL METHOD FOR FOKKER-PLANCK EQUATIONS
Mathematical Modelling and Analysis, 2023 A composite generalized Laguerre pseudospectral method for the nonlinear Fokker-Planck equations on the whole line is developed. Some composite generalized Laguerre interpolation approximation results are established. As an application, a composite Laguerre pseudospectral scheme is provided for the problems of the relaxation of fermion and boson gases.

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

On the Laguerre Method for Separating the Roots of Algebraic Equations [PDF]
Proceedings of the American Mathematical Society, 1957 where f--f(x), f(x) = 0 is an algebraic equation of degree N with real roots and x an arbitrary real number, separate the roots of the equation. This proposition was also discussed by Ch. Hermite [2 ] and by E. Bodewig [N]. According to the proposition there will be at least one root of the equation between u and v. A generalization of the relation (1),

The guaranteed convergence of Laguerre-like method
Computers & Mathematics with Applications, 2003 The authors continue their study of a Laguerre-like method for the simultaneous computation of all zeros of polynomial. The method, recently presented by the first author [J. Comput. Appl. Math. 152, No. 1--2, 451--465 (2003; Zbl 1022.65053)], is recalled together with estimates and inequalities necessary for the convergence analysis.
