On one rational integral operator of Fourier – Chebyshev type and approximation of Markov functions
Журнал Белорусского государственного университета: Математика, информатика, 2020 The purpose of this paper is to construct an integral rational Fourier operator based on the system of Chebyshev – Markov rational functions and to study its approximation properties on classes of Markov functions. In the introduction the main results of

Effective R-Matrix Parameterizations for Nuclear Data* [PDF]
EPJ Web of ConferencesWe derive an effective Reich-Moore approximation (RMA) of the Wigner-Eisenbud R-matrix formalism parameterized by complex-valued resonance energies and widths; this RMA exactly reproduces the total eliminated cross section.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Polynomial approximations in the complex plane
Journal of Computational and Applied Mathematics, 1987 The Lanczos \(\tau\)-method yields polynomial approximations for analytic functions which satisfy linear differential equations with polynomial coefficients. In particular, if the perturbation is proportional to the Faber or Chebyshev polynomials of a specific region G, then the method produces near-minimax polynomial approximations on G.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

The Faber polynomials for annular sectors and an application to the iterative solution of linear systems of equations [PDF]
, 1994 A conformal mapping of the exterior of the unit circle to the exterior of a region of the complex plane determines the Faber polynomials for that region.
