Approach to Parton Equilibration *
Perturbative QCD-based models of parton production and equilibration in ultrarela-tivistic heavy ion collisions are reviewed with an emphasis on the treatment of quantum interference effects. Uncertainties in the initial parton production and their effects on later parton equilibration are considered. Probes of early parton dynamics are also discussed.
متن کاملEquilibration in orthodontic practice.
THE completed orthodontic result cannot be left to “settle in” following active treatment. When necessa,ry, it must be harmonized by posttreatment therapy. This posttreatment phase may tax the skill, both clinical and biologic, of the orthodontist and the general practitioner. During the posttreatment phase good facial growth as well as a good functional relationship of the dentition may sustai...
متن کاملStochastic Matrix-Free Equilibration
We present a novel method for approximately equilibrating a matrix using only multiplication by the matrix and its transpose. Our method is based on convex optimization and projected stochastic gradient descent, using an unbiased estimate of a gradient obtained by a randomized method. Our method provably converges in expectation and empirically gets good results with a small number of iteration...
متن کاملStrangeness, Equilibration, Hadronization
In these remarks I explain the motivation which leads us to consider chemical nonequilibrium processes in flavor equilibration and in statistical hadroniziation of quark–gluon plasma (QGP). Statistical hadronization allowing for chemical non-equilibrium is introduced. The reesults of fits to RHIC-130 results, including multistrange hadrons, are shown to agree only with the model of an exploding...
متن کاملEquilibration of granular subsystems†
We experimentally investigate the steady states of two granular assemblies differing in their material properties and allowed to exchange volume with each other under external agitation in the vicinity of their jamming transition. We extract the statistics of various static and dynamic quantities, and uncover a materials-independent relationship between the average packing fraction and its fluc...
