    Notes: [Auszug] The study of networks pervades all of science, from neurobiology to statistical physics. The most basic issues are structural: how does one characterize the wiring diagram of a food web or the Internet or the metabolic network of the bacterium Escherichia coli? Are there any unifying principles ...

    Notes: [Auszug] Thousands of the world's languages are vanishing at an alarming rate, with 90% of them being expected to disappear with the current generation. Here we develop a simple model of language competition that explains historical data on the decline of Welsh, Scottish Gaelic, Quechua (the most common ...

    Notes: [Auszug] WE ALL have clocks inside of us. These internal oscillators control the daily cycles of body temperature, sleep and wakeful-ness, hormone titre, metabolism and so on. Chronobiology is the study of such biological rhythms and the endogenous clocks which generate them. Although physiological ...

    Human sleep and circadian rhythms: a simple model based on two coupled oscillators (1987)
    Springer
    Journal of mathematical biology 25 (1987), S. 327-347 
    Details
    ISSN: 1432-1416
    Keywords: Sleep ; Circadian ; Human ; Model ; Oscillator
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Mathematics
    Notes: Abstract We propose a model of the human circadian system. The sleep-wake and body temperature rhythms are assumed to be driven by a pair of coupled nonlinear oscillators described by phase variables alone. The novel aspect of the model is that its equations may be solved analytically. Computer simulations are used to test the model against sleep-wake data pooled from 15 studies of subjects living for weeks in unscheduled, time-free environments. On these tests the model performs about as well as the existing models, although its mathematical structure is far simpler.
