Single particle momentum spectra are calculated within three microcanonical statistical ensembles, namely, with conserved system energy, system momentum, as well as system energy and momentum. Deviations from the exponential spectrum of the grand canonical ensemble are quantified and discussed. For mean particle multiplicity and temperature, typical for p + p interactions at the LHC energies, the effect of the conservation laws extends to transverse momenta as low as about 3GeV/c. The presented results should be considered as the next step in development of statistical models for particle production in high energy collisions. They can be useful to interpret spectra measured in nuclear collisions at high energies, in particular, their system size dependence. [ABSTRACT FROM AUTHOR]

A general overview of the results obtained by the ALICE experiment from the analysis of the Pb--Pb data sample collected at the end of 2010 during the first heavy-ion run at the LHC is presented. [ABSTRACT FROM AUTHOR]

The double power-law function, p(x) ~ 1/(xb + cxd) where x is the degree of one node, and b, c, d are parameters, is used to fit the degree distribution of urban road network of Le Mans city in France. It is called "double power-law" since it behaves as two power laws respectively, in large and small degree region with a crossing in-between. The position of the crossing point is derived as a function of the three parameters. The probabilistic uncertainty of this law is studied with two possible information measures: a generalized measure called varentropy and the Shannon entropy formula. [ABSTRACT FROM AUTHOR]

The ALICE experiment at CERN is now ready to take data in proton-proton and ultra-relativistic heavy-ion collisions at LHC. This paper starts with a description of the ALICE experimental setup and its excellent tracking and particle identification capabilities. Then we discuss the ways to probe the hot and dense medium created at multi-TeV energies by measuring the yields and kinematic characteristics of strange and heavy-flavour particles produced in these collisions.
