FORMATION OF AGRO-INDUSTRIAL CLUSTER ON THE PRIORITY SOCIAL AND ECONOMIC DEVELOPMENT AREA OF THE MONO-INDUSTRY TOWN

Issues on the development of mono-industry towns in Russia through diversification of economics thereof may be addressed by formation of the priority social and economic development area (PSEDA). By the results of analysis of conditions to create intraregional (municipal) industrial clusters within the PSEDA mono-industry towns, the feasibility of such clusters is justified to turn into the priority residents of PSEDA, but also to obtain the synergistic effect of taking PSEDA advantages and the cluster approach in diversifying the economies of mono- industry towns. In contrast to previous definitions, the authors consider the intraregional (municipal) industrial cluster as the concept created with favorable involvement of regional and municipal authorities to develop the cluster strategy and use favorable conditions to expand private enterprises, association of entities to implement projects on diversification of mono-industry town economies and investment projects that meet the PSEDA requirements. The principles of PSEDA-based cluster formation in mono-industry towns are formulated. The most significant factors of sustainable development of clusters are highlighted to address mono-town problems. The stage-by-stage creation of municipal clusters proposed by authors is based on their ability to emerge during the extensive market mechanism performance and includes stages to assess the potential to form and develop cluster formations, but also the stages to identify the needs of participating entities in the course of particular interaction, creation and development of entity networks. The analysis of existing agglomerations, systematization of SWOT analysis findings, assessment of factors contributing to cluster formation offered the chance to determine the perspective for the agro-industrial cluster development in Yurga in the Kemerovo Region. The study results represent the particular contribution to the cluster theory, regional economy in terms of development of tools to form municipal industrial clusters within the PSEDA for the purpose to diversify economies of mono-industry towns. The practical significance of the research is the possibility to apply the study results in the activity of regional and municipal authorities when identifying intraregional agglomerations, creating cluster formations as PSEDA mono- town residents

Following Gluonic World Lines to Find the QCD Coupling in the Infrared

Using a parametrization of the Wilson loop with the minimal-area law, we calculate the polarization operator of a valence gluon, which propagates in the confining background. This enables us to obtain the infrared freezing (i.e. finiteness) of the running strong coupling in the confinement phase, as well as in the deconfinement phase up to the temperature of dimensional reduction. The momentum scale defining the onset of freezing is found both analytically and numerically. The nonperturbative contribution to the thrust variable, originating from the freezing, makes the value of this variable closer to the experimental one.Comment: 25 pages, 5 figure

Measurement of event-shape observables in Z→ℓ+ℓ− events in pp collisions at √ s=7 TeV with the ATLAS detector at the LHC

Event-shape observables measured using charged particles in inclusive $Z$-boson events are presented, using the electron and muon decay modes of the $Z$ bosons. The measurements are based on an integrated luminosity of $1.1 {\rm fb}^{-1}$ of proton--proton collisions recorded by the ATLAS detector at the LHC at a centre-of-mass energy $\sqrt{s}=7$ TeV. Charged-particle distributions, excluding the lepton--antilepton pair from the $Z$-boson decay, are measured in different ranges of transverse momentum of the $Z$ boson. Distributions include multiplicity, scalar sum of transverse momenta, beam thrust, transverse thrust, spherocity, and $\mathcal{F}$-parameter, which are in particular sensitive to properties of the underlying event at small values of the $Z$-boson transverse momentum. The Sherpa event generator shows larger deviations from the measured observables than Pythia8 and Herwig7. Typically, all three Monte Carlo generators provide predictions that are in better agreement with the data at high $Z$-boson transverse momenta than at low $Z$-boson transverse momenta and for the observables that are less sensitive to the number of charged particles in the event.Comment: 36 pages plus author list + cover page (54 pages total), 14 figures, 4 tables, submitted to EPJC, All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/STDM-2014-0

Phase coherence and energy relaxation in epitaxial graphene under microwave radiation

We have performed low-temperature magnetotransport measurements on monolayer epitaxial graphene under microwave radiation and extracted the radiation-induced effective temperatures, energy relaxation, and the dephasing times. We established that the response of the graphene sample is entirely bolometric at least up to 170 GHz. Dynamic dephasing, i.e., the time-reversal symmetry breaking effect of the ac electromagnetic field rather than mediated by heating, may become significant in the terahertz frequency range and in samples with longer phase coherence time

Optical and magneto-optical properties of Fe 4−x Co x (x=1–3)

We report a systematic study of the electronic, optical, and magneto-optical properties of the Fe4-xCox (x = 1–3) compounds using the full-potential linearized augmented plane waves (FPLAPW) method within the local spin density approximation (LSDA). Pure Fe (x = 0) and Co (x = 4) have also been studied, the latter in hcp as well as bcc structure, to offer a better comparison. A good agreement is obtained between calculated optical conductivity spectra and experimental data. We note that the magneto-optical properties of these compounds are found to be more akin to those of bcc Co (which has MOKE very similar to that of bcc Fe) than to those of hcp Co. This shows strong impact of the environment on the MOKE of these compounds. With respect to the elemental values, the magnetic moments at Fe sites are found to be larger in general, while those at Co sites are almost the same. However, interestingly, despite their larger magnetic moment, the Kerr rotation remains comparable to that of bcc Fe for most of the energy range. The origin of Kerr spectra has been explained in terms of optical transitions
