Sobre la inversión de los potenciales de Bessel-Riesz Sobre la inversión de los potenciales de Bessel-Riesz

open access: yesNexo, 2010
En este trabajo se obtiene la inversión de un operador del tipo convolución usando técnicas de integrales hipersingulares. El operador de Bessel-Riesz de una función ϕ perteneciente a S , el espacio de funciones de prueba de Schwartz, es definido por la ...

Laguerre-type Bessel functions

open access: yes, 2005
In the framework of the 'monomiality principle', we introduce a class of Bessel-type functions which can be derived by applying the properties of an isomorphism, related to the so called Laguerre-type exponentials.

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

open access: yesAdvanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Behavior of Bessel functions in neuron with multi-dendrites

open access: yesAIP Advances
This study investigates the integration of Bessel functions as activation functions within multi-dendritic neurons, aiming to address the limitations of traditional activation functions, such as sigmoid and ReLU.

On the Matrix Versions of Incomplete Extended Gamma and Beta Functions and Their Applications for the Incomplete Bessel Matrix Functions

open access: yesComplexity, 2021
In this paper, we first introduce the incomplete extended Gamma and Beta functions with matrix parameters; then, we establish some different properties for these new extensions. Furthermore, we give a specific application for the incomplete Bessel matrix

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

open access: yesChemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

The Schrödinger Equation for a Free Particle: Generalized Bessel Solutions

open access: yesAxioms
We demonstrate the time evolution of a free particle in a three-dimensional space given that the initial condition is any arbitrary radial function f(r).

On the Evaluation of Bessel Functions

open access: yesApplied and Computational Harmonic Analysis, 1993
The author presents an algorithm for the evaluation of Bessel functions \(J_ \nu(x)\), \(Y_ \nu(x)\) and \(H_ \nu^{(j)}(x)\) \((j=1,2)\) of arbitrary positive orders and arguments. This algorithm consists of two parts: One of them combines the evaluation of the function \(H_ \nu^{(1)}(x)\) via Taylor expansions and via numerical computation of the ...
