A synthetic low-frequency mammalian oscillator [PDF]
Nucleic Acids Research, 2010 Circadian clocks have long been known to be essential for the maintenance of physiological and behavioral processes in a variety of organisms ranging from plants to humans. Dysfunctions that subvert gene expression of oscillatory circadian-clock components may result in severe pathologies, including tumors and metabolic disorders.

HIGH AND LOW FREQUENCY OSCILLATIONS IN DRUG EPIDEMICS [PDF]
International Journal of Bifurcation and Chaos, 2006 We extend the two-dimensional model of drug use introduced in [Behrens et al., 1999, 2000, 2002] by considering two additional states that represent in more detail newly initiated ("light") users' response to the drug experience. Those who dislike the drug quickly "quit" and briefly suppress initiation by others.

Identification of low frequency oscillation modes in large transmission systems
Revista Facultad de Ingeniería Universidad de Antioquia, 2017 Existe un comportamiento dinámico típico asociado a todo sistema. Las oscilaciones son fenómenos inherentes a los sistemas dinámicos, por lo que el análisis de estos resulta fundamental para entender el comportamiento dinámico de un sistema en particular.
