    The presented paper deals with an approach to the evolution of methodology of economy innovative development from the standpoint of analyzing the interaction of its actors – from a Triple to a Penta Helix. The article proposes the provisions for such a methodology based on expanding the range of actors of innovative development as public interests shift from the emergence of a free enterprise economy to a socially oriented knowledge economy and further to a balanced and environmentally friendly production and consumption. A special role in the presented approach is given to the analysis of the place of universities in the fivefold spiral of innovative transformation of economy – as a creator of sustainable development values. The authors proved that the Penta Helixis the result of the evolution of the Quadruple Helix in the conditions of increasing the values of sustainable development. In turn, the core of the QuadrupleHelix– the Triple Helix– acts as the core in the Penta Helix. The article highlights three varieties of the TripleHelix model that is dominant today in industrialized countries, shows their connection with the peculiarities of the innovative development of the Russian economy. On this basis, it was concluded that the progress in building the Penta Helix of innovative development in Russia depends on the emergence of new actors – the subjects of the green economy and civil society, and the full expression of their economic interestsВ представленной статье рассматривается подход к эволюции методологии развития инновационной экономики с позиций анализа взаимодействия ее акторов – от тройной к пятеричной спирали. В статье предлагаются положения методологии, основанной на расширении круга акторов инновационного развития по мере смещения общественного интереса от становления экономики свободного предпринимательства к социально ориентированной экономике знаний и далее – к сбалансированному и экологически безопасному производству и потреблению. Особая роль в представленном подходе отводится анализу места университетов в пятеричной инновационной трансформации экономики – как создателей ценностей устойчивого развития. Авторы доказали, что пятеричная спираль является результатом эволюции четверной спирали инноваций в условиях повышения роли ценностей устойчивого развития. В свою очередь, ядро четверной спирали – тройная спираль – действует и как ядро пятеричной спирали. В статье выделены три разновидности модели тройной спирали, доминирующей сегодня в промышленно развитых странах, показана их связь с особенностями инновационного развития российской экономики. На этом основании сделан вывод, что прогресс в формировании пятеричной спирали инновационного развития в России зависит от появления новых акторов – субъектов зеленой экономики и гражданского общества, полноты выражения их экономических интересо

    Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

    Get PDF
    We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

    Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

    Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

    Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

    Get PDF
    The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.
