    Notizen: We have measured and modeled the dynamics of inductively coupled discrete arrays of niobium Josephson junctions. We see splitting of the Eck step in the current-voltage characteristic. Numerical simulations reproduce this splitting and are used to find an approximate solution for the junction phases at resonance. Using the technique of harmonic balance, we find an analytic expression for the resonance frequencies and the voltages that match this splitting. We can also predict the amplitude of these oscillations. The analytical results describe both the experiments and simulations well. © 1996 American Institute of Physics.

    Notizen: [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 ...

    Notizen: [Auszug] Soon after the crowd streamed on to London's Millennium Bridge on the day it opened, the bridge started to sway from side to side: many pedestrians fell spontaneously into step with the bridge's vibrations, inadvertently amplifying them. Here we model this unexpected and now notorious ...

    Notizen: [Auszug] At lunch a few weeks ago, a colleague abruptly pulled a massive vegetable from his briefcase and passed it around the table. He was offering the rest of us a head of Romanesque broccoli — to ponder, not to eat. The surface of a Romanesque is exquisitely symmetrical, sporting dozens of ...

    Notizen: [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 ...

Ordinarily, the connection topology is assumed to be either ...

    Notizen: [Auszug] SYNCHRONIZATION of an array of non-linear oscillators — for instance, coupled Josephson junctions or semiconductor lasers — is most easily achieved if all the oscillators are identical. Or so one might have thought. On page 465 of this issue, Braiman, Lindner and Ditto provide an ...

    Notizen: [Auszug] Anyone who has ever taken a shower in an old dormitory knows that time delays can cause oscillatory instabilities. First the water is too cold, so you turn up the heat. But as you stand there shivering, the water does not get any hotter, because of delays in the antiquated heating system. If you ...
