Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Hermite Interpolational Bohemians
Companion matrices in the Lagrange basis were first tested using what are now known as Bohemian matrices. Later the Lagrange companions were extended to Hermite interpolational companions. We use those in this paper to explore the analog of Littlewood polynomials, that is, those with ±1 coefficients, in certain Hermite interpolational bases.

Likelihood Estimation for Stochastic Differential Equations with Mixed Effects
ABSTRACT Stochastic differential equations provide a powerful tool for modelling dynamic phenomena affected by random noise. When time series are observed for several experimental units, it is often the case that some of the parameters vary between the individual experimental units.

Mean Convergence of Hermite Interpolation
We study weighted mean convergence properties of Hermite interpolation based on the zeros of certain generalized Jacobi polynomials such as necessary and sufficient conditions for such convergence for all continuously differentiable functions ...

A new method for interpolating yield curve data, with applications to the South African market
This paper presents a method for interpolating yield curve data in a manner that ensures positive and continuous forward curves. As shown by Hagan and West (2006), traditional interpolation methods suffer from problems: they posit unreasonable ...

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

The distance traveled by contour wave with artificial wave velocity in a step-time is often inconsistent with the mesh size. Therefore, when the transmission boundary formula is applied, the calculation nodes of transmission boundary are usually ...
