The QCD Mixed Phase: Shaken, not Stirred
نویسندگان
چکیده
If the phase transition from quark matter to hadron gas is first order, matter at the appropriate temperatures and densities can exist as a mixed phase consisting of plasma droplets in equilibrium with a surrounding hadronic fluid. If formed in ion collisions, this mixed phase can produce large event-by-event fluctuations as the system hadronizes. Extraordinary baryon fluctuations [1] can accompany a first order transition at high baryon density [2] and, possibly, a near transition at zero baryon density [3], [4]. In ref. [1], we argued that baryon number conservation and rapid longitudinal expansion limits the extent to which post-hadronization interactions can erode fluctuations in a rapidity interval. Here, we further explore the rise and fall of these fluctuations using real-time lattice simulations [5].

Shaken, not stirred: bioanalytical study of the antioxidant activities of martinis.
BACKGROUND Moderate consumption of alcoholic drinks seems to reduce the risks of developing cardiovascular disease, stroke, and cataracts, perhaps through antioxidant actions of their alcohol, flavonoid, or polyphenol contents. "Shaken, not stirred" routinely identifies the way the famous secret agent James Bond requires his martinis. OBJECTIVES As Mr Bond is not afflicted by cataracts or car...
متن کاملStirred, Not Shaken: Motor Control with Partially Mixed Selectivity.
In this issue of Neuron, Zhang et al. (2017) demonstrate that neurons in human parietal cortex represent effector responses functionally segregated, while other movement variables are associated in a subordinated fashion. Such partially mixed selectivity facilitates efficient motor control in various behavioral contexts.
متن کاملExtended Beta Regression in R: Shaken, Stirred, Mixed, and Partitioned
This introduction to the extended features of the R package betareg is a (slightly) modified version of Grün, Kosmidis, and Zeileis (2012), published in the Journal of Statistical Software. Beta regression – an increasingly popular approach for modeling rates and proportions – is extended in various directions: (a) bias correction/reduction of the maximum likelihood estimator, (b) beta regressi...

Data Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
