[EN] Background: The respiratory epithelium is frequently infected by the respiratory syncytial virus, resulting in inflammation, a reduction in cilia activity and an increase in the production of mucus. Methods: In this ...

A new technique to obtain derivative-free methods with optimal order of convergence in the sense of the Kung-Traub conjecture for solving nonlinear smooth equations is described. The procedure uses Steffensen-like methods ...

[EN] In this paper we propose an alternative for the study of local convergence radius and the uniqueness radius for some third-order methods for multiple roots whose multiplicity is known. The main goal is to provide an ...

Representación gráfica del campo y el potencial eléctrico generado por dos cargas en el plano de valor y posición modificables. Muestra asimismo las curvas equipotenciales y las líneas de campo.

[EN] Persistent respiratory syncytial virus (RSV) infections have been associated with the exacerbation of chronic inflammatory diseases, including chronic obstructive pulmonary disease (COPD). This virus infects the ...

[EN] The paper ¿SPICE Model of Photomultiplier Tube Under Different Bias Conditions¿ is commented. We revisit the mathematical formulation to compensate for some ambiguities in the original manuscript, and point out some ...

En la imagen digital, la intensidad de cada pixel se almacena en una matriz. Mediante la descomposicion en valores singulares, se consigue analizar las variaciones de la intensidad y expresar la matriz como suma de productos ...

Gráfica de la superficie cónica a partir de sus ecuaciones paramétricas.

[EN] In this work we present a new family of iterative methods for solving nonlinear systems that are optimal in the sense of Kung and Traub’s conjecture for the unidimensional case. We generalize this family by performing ...
