Chronobiology in endocrinology.

Annali dell'Istituto superiore di sanita, 1993
Temporal endocrine structure (TES). It can be defined as a combination of predictable hormonal changes that are time-related. Regarding their frequency, endocrine rhythms may be circadian, ultradian and infradian. In this context, the endocrine circadian time structure (ECTS), that is closely dependent of some areas of the hypothalamus, is of ...

Collective dynamical response of coupled oscillators with any network structure

, 2008
We formulate a reduction theory that describes the response of an oscillator network as a whole to external forcing applied nonuniformly to its constituent oscillators.
