Generally speaking, a model of a natural system is one of many possible mathematical representation of that system, explicitly describing some of its features and supporting predictions on some other features, the latter being typically time- or environment dependent.
As he spoke, using a model of Benoît Dugardyn's set to show how the stage would be transformed during the opera's four acts, the singers passed around drawings of Johann Stegmeir's costumes: undergarments in the first act give way to increasingly flamboyant dress in the second and third, most of which is stripped away for the various rendezvous in the fourth.
But his newsstand, visually speaking, remains a model of the art form, an orderly, beckoning cornucopia of maps, guides, reading glasses, clocks, diaries, souvenir medallions, playing cards and other tourist paraphernalia, amid the various archaeology numbers, foreign newsweeklies, lads' magazines ("they don't sell like they used to," he noted gravely) and Italian dailies.
This is the case of Backstrom et al. [86] which, as discussed above, is not strictly speaking a generative model of discussion threads but a predictive model.
The next model under consideration, Backstrom et al. [86], is not strictly speaking a generative model of discussion threads, but proposes how to predict structural properties of a thread (e.g. size) by combining features of different nature.
► We simulate emergence of decisions to speak and act in a model of the human brain.
Broadly speaking, Chicago was hardly a model of social order.
In other terms, we can speak of a model in which Bim and PUMA can activate directly Bax when they are no longer antagonized by Bcl-2, Bcl-xl, and Bcl-w anti-apoptotic proteins, i.e., when Bad (or other BH3-only proteins) engages and represses Bcl-2, Bcl-xl, and Bcl-w anti-apoptotic proteins.
Gay, 30, had long presented himself as a model of clean competition who spoke out against doping.
In a hub and spoke model of a central burns unit and three peripheral hospitals, telemedicine use led to increased consultation, but burns assessment was as accurate as face-to-face assessment and reduction in transfers to burns units led to significant cost savings [[41]].
