The Transverse Energy as a Barometer of a Saturated Plasma
The evolution of the gluon plasma produced with saturation initial conditions is calculated via Boltzmann transport theory for nuclear collisions at high energy. The saturation scale increases with A and √ s, and thus we find that the perturbative rescattering rate decreases relative to the initial longitudinal expansion rate of the plasma. The effective longitudinal pressure remains significan...
متن کاملInternet comments as a barometer of public opinion
Social susceptibility is defined and analyzed using data from CNN news website. The current models of opinion dynamics, voting, and herding in closed communities are extended, and the community’s response to the injection of a group with predetermined and permanent opinions is calculated. A method to estimate the values of possible response in Internet communities that follow a specific develop...
متن کاملThe thymus: a barometer of malnutrition.
In 1810 J. F. Menkel noted that the human thymus was especially sensitive to malnutrition (see Jackson, 1925; Beisel, 1992), and the term ‘nutritional thymectomy’ came into common usage. By 1845 Simon (1845) had observed that the thymus is ‘a barometer of malnutrition, and a very sensitive one’. These observations were made over a century before the role of the thymus in lymphocyte development ...
متن کاملThe Ionosphere as a Measure of Solar Activity
-Critical frequencies of all regular ionospheric layers vary diurnally, seasonally, with geographic latitude and longitude, and with solar activity so that, for any location and any seacon fo _G(t) + H(t)S where fø is the critical frequency, G and H are functions of (t), the time of day, and S is the sunspot-number. For locations where such ionospheric trends are well established, observations ...
