A Transference Result of the Lp-Continuity of the Jacobi Littlewood-Paley g-Function to the Gaussian and Laguerre Littlewood-Paley g-Function

open access: yesJournal of Function Spaces, 2018
We develop a transference method to obtain the Lp-continuity of the Gaussian-Littlewood-Paley g-function and the Lp-continuity of the Laguerre-Littlewood-Paley g-function from the Lp-continuity of the Jacobi-Littlewood-Paley g-function, in dimension one,

Model observer task‐based assessment of computed tomography metal artifact reduction using a hip arthroplasty phantom

open access: yesMedical Physics, Volume 52, Issue 6, Page 3723-3733, June 2025.
Abstract Background The United States Food and Drug Administration (FDA) recently published a model observer‐based framework for the objective performance assessment of computed tomography (CT) metal artifact reduction (MAR) algorithms and demonstrated the framework's feasibility in the low‐contrast detectability (LCD) task‐based assessment of MAR ...

Time‐Series Factor Modeling and Selection

open access: yesJournal of Financial Research, Volume 48, Issue 2, Page 839-875, Summer 2025.
Abstract The article proposes a statistical time‐series factor model that incorporates deterministic orthogonal trend polynomials. Such polynomials allow capturing variation in returns without initially identifying a set of robust time‐series factors.

A generalization of the classical Laguerre polynomials [PDF]

open access: yesRendiconti del Circolo Matematico di Palermo, 1995
We consider a modi cation of the gamma distribution by adding a discrete measure supported in the point x = 0. For large n we analyze the existence of orthogonal polynomials with respect to such a distribution. Finally we represent them as the hypergeometric function 3F3:

Towards data‐driven stochastic predictive control

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 7, Page 2588-2610, 10 May 2025.
Summary Data‐driven predictive control based on the fundamental lemma by Willems et al. is frequently considered for deterministic LTI systems subject to measurement noise. However, little has been done on data‐driven stochastic control. In this paper, we propose a data‐driven stochastic predictive control scheme for LTI systems subject to possibly ...

On a family of q-modified-Laguerre-Appell polynomials

open access: yesArab Journal of Basic and Applied Sciences
This paper aims to introduce a new class of special polynomials called q-modified Laguerre-Appell polynomials. Some definitions and concepts related to this class of polynomials, including generating function and series definition are explored.

Equioscillatory property of the Laguerre polynomials

open access: yesJournal of Approximation Theory, 2010
AbstractWe show that the function ((x−dm)(x−dM))1/4xα/2e−x/2Lk(α)(x) is almost equioscillating with the amplitude 2/π provided k and α are large enough. Here Lk(α)(x) is the orthonormal Laguerre polynomial of degree k and dm,dM are some approximations for the extreme zeros. As a corollary we obtain a very explicit, uniform in k and α, sharp upper bound

High‐Fidelity Information Transmission Through the Turbulent Atmosphere Utilizing Partially Coherent Cylindrical Vector Beams

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
A novel free‐space optical communication protocol that combines the benefits of partially coherent light sources with the decoding capabilities of convolutional neural networks is proposed. This approach establishes a robust communication link that can withstand atmospheric turbulence.
