Исследование влияния трансформации региональной экономики на уровень жизни населения

The article presents results of a study on determining the directions for structural transformation of economy of the Krasnoyarsk Territory which would promote sustainable economic development and thus improve the performance of current economic system. This study revealed the degree to which the structure of territory economy can affect the key indicator of economic performance of the region - that is living standards of the population. This research was conducted, using cluster analysis and similarity evaluation, it demonstrated that one of the conditions for improving the regional economy’s resistance to external and internal factors is to increase the share of the following kinds of activities in the structure of territorial GRP: «Agriculture, hunting and forestry» (OKVED, Section A) and «Wholesale and retail trade; repair of motor vehicles, motorcycles and personal and household goods» (OKVED, Section G) - which should be followed by the reduction of the existing dependency of the economic system from mining and quarrying. In the same vein evaluation of series of regression models proved that structure of regional economy and the changes that it had undergone over the period in question, failed to demonstrate significant impact on living standards indicators, such as average wages and median age at death. The conclusions, that were formulated on the basis of this research can be taken into account during the decision making process by those state authorities of the Krasnoyarsk territory that are responsible for implementing regional economic policy.В статье представлены результаты исследования, цель которого заключалась в определении основных направлений структурной трансформации экономики Красноярского края, способствующих устойчивому экономическому развитию и, как следствие, повышению эффективности существующей экономической системы. В ходе исследования также определено, в какой степени структура краевой экономики способна повлиять на изменение уровня жизни населения - одного из ключевых индикаторов экономической эффективности региона. Исследование, проведенное с использованием методов кластерного анализа и анализа подобия, показало, что одним из условий повышения уровня устойчивости экономики края к неблагоприятным воздействиям внешних и внутренних факторов является увеличение в структуре краевого ВРП удельного веса таких видов деятельности, как «Сельское хозяйство, охота и лесное хозяйство» (раздел А ОКВЭД) и «Оптовая и розничная торговля; ремонт автотранспортных средств, мотоциклов, бытовых изделий и предметов личного пользования» (раздел G ОКВЭД), которое должно сопровождаться снижением существующей зависимости экономической системы от добычи полезных ископаемых. Вместе с тем оценка серии регрессионных моделей позволила получить доказательства в пользу того, что структура краевой экономики, как и изменения, происходившие в ней на протяжении анализируемого периода, не демонстрирует значимого влияния на формирование таких показателей уровня жизни населения, как средняя заработная плата и медианный возраст смерти. Сформулированные в результате исследования выводы могут иметь практическую значимость при принятии решений органами государственного управления Красноярского края, ответственными за реализацию региональной экономической политики

A Search for Dark Higgs Bosons

Recent astrophysical and terrestrial experiments have motivated the proposal of a dark sector with GeV-scale gauge boson force carriers and new Higgs bosons. We present a search for a dark Higgs boson using 516 fb-1 of data collected with the BABAR detector. We do not observe a significant signal and we set 90% confidence level upper limits on the product of the Standard Model-dark sector mixing angle and the dark sector coupling constant.Comment: 7 pages, 5 postscript figures, published version with improved plots for b/w printin

B0 meson decays to rho0 K*0, f0 K*0, and rho-K*+, including higher K* resonances

We present branching fraction measurements for the decays B0 -> rho0 K*0, B0 -> f0 K*0, and B0 -> rho- K*+, where K* is an S-wave (K pi)_0* or a K*(892) meson; we also measure B0 -> f0 K_2*(1430)^0. For the K*(892) channels, we report measurements of longitudinal polarization fractions (for rho final states) and direct CP-violation asymmetries. These results are obtained from a sample of (471.0 +/- 2.8) x 10^6 BBbar pairs collected with the BaBar detector at the PEP-II asymmetric-energy e+ e- collider at the SLAC National Accelerator Laboratory. We observe rho0 K*(892)^0, rho0 (K pi)_0^{*0}, f0 K*(892)^0, and rho- K*(892)+ with greater than 5 sigma significance, including systematics. We report first evidence for f0 (K pi)_0^{*0} and f0 K_2*(1430)^0, and place an upper limit on rho- (K pi)_0^{*+}. Our results in the K*(892) channels are consistent with no direct CP-violation.Comment: 17 pages, 6 postscript figures, submitted to Phys. Rev.

Measurement of the Ratio of b Quark Production Cross Sections in Antiproton-Proton Collisions at 630 GeV and 1800 GeV

We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at 630 GeV to 1800 GeV using bottom quarks with transverse momenta greater than 10.75 GeV identified through their semileptonic decays and long lifetimes. The measured ratio sigma(630)/sigma(1800) = 0.171 +/- .024 +/- .012 is in good agreement with next-to-leading order (NLO) quantum chromodynamics (QCD)

Estimating Total Quantitative Protein Content in <i>Escherichia coli</i>, <i>Saccharomyces cerevisiae</i>, and HeLa Cells

The continuous improvement of proteomic techniques, most notably mass spectrometry, has generated quantified proteomes of many organisms with unprecedented depth and accuracy. However, there is still a significant discrepancy in the reported numbers of total protein molecules per specific cell type. In this article, we explore the results of proteomic studies of Escherichia coli, Saccharomyces cerevisiae, and HeLa cells in terms of total protein copy numbers per cell. We observe up to a ten-fold difference between reported values. Investigating possible reasons for this discrepancy, we conclude that neither an unmeasured fraction of the proteome nor biases in the quantification of individual proteins can explain the observed discrepancy. We normalize protein copy numbers in each study using a total protein amount per cell as reported in the literature and create integrated proteome maps of the selected model organisms. Our results indicate that cells contain from one to three million protein molecules per µm3 and that protein copy density decreases with increasing organism complexity

Amplitude analysis of B^{0}→K^{+}π^{-}π^{0} and evidence of direct CP violation in B→K*π decays

We analyze the decay B(0) -> K(+) pi(-) pi(0) with a sample of 4.54 x 10(8) B (B) over bar events collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, and extract the complex amplitudes of seven interfering resonances over the Dalitz plot. These results are combined with amplitudes measured in B(0) -> K(S)(0)pi(+)pi(-) decays to construct isospin amplitudes from B(0) -> K* pi and B(0) -> rho K decays. We measure the phase of the isospin amplitude Phi(3/2), useful in constraining the Cabibbo-Kobayashi-Maskawa unitarity triangle angle gamma and evaluate a CP rate asymmetry sum rule sensitive to the presence of new physics operators. We measure direct CP violation in B(0) -> K*(+) pi(-) decays at the level of 3 sigma when measurements from both B(0) -> K(+) pi(-) pi(0) and B(0) -> K(S)(0) pi(+) pi(-) decays are combined

Search for CP violation in the decay τ^{-}→π^{-}K_{s}^{0}(≥Oπ^{0})ν_{τ}

We report a search for CP violation in the decay τ-→π-KS0(≥0π0)ντ using a data set of 437×106 τ-lepton pairs, corresponding to an integrated luminosity of 476  fb-1, collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage rings. The CP-violating decay-rate asymmetry is determined to be (-0.36±0.23±0.11)% approximately 2.8 standard deviations from the standard model prediction of (0.36±0.01)%

B0 meson decays to ρ0K∗0, f0K∗0, and ρ−K∗+, including higher K∗ resonances

We present branching fraction measurements for the decays B0→ρ0K*0, B0→f0K*0, and B0→ρ-K*+, where K* is an S-wave (Kπ)0* or a K*(892) meson; we also measure B0→f0K2*(1430)0. For the K*(892) channels, we report measurements of longitudinal polarization fractions (for ρ final states) and direct CP violation asymmetries. These results are obtained from a sample of (471.0±2.8)×106 BB̅ pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at the SLAC National Accelerator Laboratory. We observe ρ0K*(892)0, ρ0(Kπ)0*0, f0K*(892)0, and ρ-K*(892)+ with greater than 5σ significance, including systematics. We report first evidence for f0(Kπ)0*0 and f0K2*(1430)0, and place an upper limit on ρ-(Kπ)0*+. Our results in the K*(892) channels are consistent with no direct CP violation

Measurement of the gamma gamma* -> eta c transition form factor

We study the reaction e(+)e(-) -> e(+)e(-) eta(c), eta(c) -> K(S)K(+/-)pi(-/+) and obtain eta(c) mass and width values 2982.2 +/- 0.4 +/- 1.6 MeV/c(2) and 31.7 +/- 1.2 +/- 0.8 MeV, respectively. We find Gamma(eta(c) -> gamma gamma)B(eta(c) -> KK pi) = 0.374 +/- 0.009 +/- 0.031 keV, and measure the gamma gamma* -> eta(c) transition form factor in the momentum transfer range from 2 to 50 GeV(2). The analysis is based on 469 fb(-1) of integrated luminosity collected at PEP-II with the BABAR detector at e(+)e(-) center-of-mass energies near 10.6 GeV.

Searches for Lepton flavor violation in the decays tau(+/-) -> e(+/-)gamma and tau(+/-) -> mu(+/-)gamma

Searches for lepton-flavor-violating decays of a tau lepton to a lighter mass lepton and a photon have been performed with the entire data set of (963 +/- 7) x 10(6) tau decays collected by the BABAR detector near the Y(4S), Y(3S) and Y(2S) resonances. The searches yield no evidence of signals and we set upper limits on the branching fractions of B(tau(+/-) -> e(+/-)gamma) mu(+/-)gamma) < 4.4 X 10(-8) at 90% confidence level
