Sobre la equivalencia dinámica entre redes de reacción quimica respecto de la sensibilidad de de constantes cinéticas a factores externos.
Padrón Páez, Juan Ismael (2014)"El dogma fundamental de la cinética química establece que puede existir más de una Red de Reacción Química (RRQ) que representa la realidad experimental en reacciones. Más aún, estas RRQ no necesariamente comparten el ... -
Stabilization of a class of biomedical systems via stability preservation
Solís Perales, Gualberto Celestino; Ruíz Velázquez, Eduardo; Femat Flores, Alejandro Ricardo; Fernández Anaya, Guillermo (2008)"We present a method for stabilization of a class of nonlinear systems.
