of state below and above
A unique parameterization of the QCD equation of state below and above T c We present a unique parameterization of the equation of state of strongly interacting matter in the temperature interval 0.6T c · · · 3T c at µ = 0 within a quasi-particle model based on quark and gluon degrees of freedom. The extension to non-vanishing baryon-chemical potential is discussed.
متن کاملScalar mesons above and below 1 GeV
We show that two nonets and a glueball provide a consistent description of data on scalar mesons below 1.7 GeV. Above 1 GeV the states form a conventional qq̄ nonet mixed with the glueball of lattice QCD. Below 1 GeV the states also form a nonet, as implied by the attractive forces of QCD, but of more complicated nature. Near the center they are (qq)3̄(q̄q̄)3 in S-wave, with some qq̄ in P-wave, but ...
متن کاملParameterizing above or below guaranteed values
We consider new parameterizations of NP-optimization problems that have nontrivial lower and/or upper bounds on their optimum solution size. The natural parameter, we argue, is the quantity above the lower bound or below the upper bound. We show that for every problem in MAX SNP, the optimum value is bounded below by an unbounded function of the input-size, and that the above-guarantee paramete...
متن کاملGastric Cancer in people below and above 40 is it different?
Abstract Background: Gastric cancer is the second most common cancer and also the second cancer related death all over the world. In recent years recorded data for tumor has shown a rise in the incidence of gastric cancer in young individuals. The present study was designed to compare some of the epidemiologic characteristics of individuals suffering from gastric cancer aged below a...
متن کاملScaling Lightness Perception and Differences Above and Below Diffuse White
The first purpose of this thesis was to design and complete psychophysical experiments for scaling lightness and lightness differences for achromatic percepts above and below the lightness of diffuse white (L*=100). Below diffuse white experiments were conducted under reference conditions recommended by CIE for color difference research. Overall a range of CIELAB lightness values from 7 to 183 ...
