Radius evolution for bubbles with elastic shells
(Elsevier, 2021)
"We present an analysis of an extended Rayleigh–Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) ...
Factorization method for some inhomogeneous Lienard equations
(Sociedad Mexicana de Física, A. C., 2021)
"The factorization of inhomogeneous Li\'enard equations is performed showing that through the factorization conditions involved in the method one can obtain forcing terms for which closed-form solutions exist. Because of ...
Generalized Cornu-type spirals and their Darboux parametric deformations
(Elsevier, 2019)
"We generalize the Fresnel integrals and introduce a class of spirals F-n, which contains the Cornu spiral as the case F-2. Their Darboux parametric deformations are also investigated. The F-3 spiral and some of its Darboux ...
Factorization of the Riesz-Feller Fractional Quantum Harmonic Oscillators
(IOP Publishing, 2020)
"Using the Riesz-Feller fractional derivative, we apply the factorization algorithm to the fractional quantum harmonic oscillator along the lines previously proposed by Olivar-Romero and Rosas-Ortiz, extending their results. ...
Planar motion with Fresnel integrals as components of the velocity
(Sociedad Mexicana de Física, A.C., 2020)
"We analyze the two-dimensional motion of a rigid body due to a constant torque generated by a force acting on the body parallel to the surface on which the body moves extending an old note of Ferris-Prabhu [Am. J. Phys. ...
Wavelet characterization of hyper-chaotic time series
(Sociedad Mexicana de Física, A.C., 2018)
A wavelet scaling numerical characterization of time series based on the variance of the wavelet coefficients is used for three well-known four-dimensional and one five-dimensional hyper-chaotic systems. We report several ...
Stability analysis of orbital modes for a generalized Lane-Emden equation
(Elsevier, 2019)
"We present a stability analysis of the standard nonautonomous systems type for a recently introduced generalized Lane-Emden equation which is shown to explain the presence of some of the structures observed in the atomic ...
Relativistic Rotating Electromagnetic Fields
(Hindawi, 2020)
"In this work, we consider axially symmetric stationary electromagnetic fields in the framework of special relativity. These fields have an angular momentum density in the reference frame at rest with respect to the axis ...
Non-autonomous Ginzburg-Landau solitons using the He-Li mapping method
(Universidad Autónoma del Estado de México, 2020)
"We find and discuss the non-autonomous soliton solutions in the case of variable nonlinearity and dispersion implied by the Ginzburg-Landau equation with variable coefficients. In this work we obtain non-autonomous ...
Vanishing Poynting Observers and Electromagnetic Field Classification in Kerr and Kerr-Newman Spacetimes
(Hindawi, 2022)
"We consider electromagnetic fields having an angular momentum density in a locally nonrotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of such fields is assessed with two families ...
