In mammals, the circadian pacemaker, which controls daily rhythms, is located in the
suprachiasmatic nucleus (SCN). Circadian oscillations are generated in individual SCN neurons by …

Recent work on human vocal production demonstrates that certain irregular phenomena
seen in human pathological voices and baby crying result from nonlinearities in the vocal …

A two‐mass model of vocal‐fold vibrations is analyzed with methods from nonlinear dynamics.
Bifurcations are located in parameter planes of physiological interest (subglottal pressure, …

PERIOD (PER) proteins are central components within the mammalian circadian oscillator,
and are believed to form a negative feedback complex that inhibits their own transcription at …

To establish a framework for discussing mammalian vocalizations, relevant terminology and
concepts from the theory of nonlinear dynamics are introduced. It is suggested that a variety …

Lymphocytes circulate through lymph nodes (LN) in search for antigen in what is believed to
be a continuous process. Here, we show that lymphocyte migration through lymph nodes …

Circadian clocks are endogenous oscillators driving daily rhythms in physiology and
behavior. Synchronization of these timers to environmental light–dark cycles (‘entrainment’) is …

The complexity of tissue- and day time-specific regulation of thousands of clock-controlled
genes (CCGs) suggests that many regulatory mechanisms contribute to the transcriptional …

Human beings exhibit wide variation in their timing of daily behavior. We and others have
suggested previously that such differences might arise because of alterations in the period …

Multiple Arabidopsis thaliana clones from an experimental series of cDNA microarrays are
evaluated in order to identify essential sources of noise in the spotting and hybridization …
