    Nowadays modern economic system and banking system in particular is defined as a globally developed and integrated system. Internet banking gained particular interest as a kind of remote banking, which is the most progressive direction of banking system development. It is one of the most dynamic and rapidly developing sectors of the e-Commerce market. The issues of strategic development determine the interest, attracted to the development of internet banking. Practice shows that investments in such projects begin to make a profit only after a certain period of time necessary for training and adapting the system to specific conditions. Investing in software, computer and telecommunications equipment and creating a base for the transition to new computing platforms, provide banks with ability to reduce the cost of services, accelerate the payments transactions through the banking system and reduce the complexity of banking services. The largest banks provide the richest set of internet banking services abroad. Internet banking in supply chain of Russia is at the stage of formation. In order to reach the modern level of development of the banking sector, it is essential for supply chain of Russia to form a national market for internet banking. The development of remote banking services based on Internet banking technology will give a new impetus to the development of electronic banking services in banking

    Hard probes in heavy ion collisions at the LHC: heavy flavour physics

    Full text link
    We present the results from the heavy quarks and quarkonia working group. This report gives benchmark heavy quark and quarkonium cross sections for pppp and pApA collisions at the LHC against which the AAAA rates can be compared in the study of the quark-gluon plasma. We also provide an assessment of the theoretical uncertainties in these benchmarks. We then discuss some of the cold matter effects on quarkonia production, including nuclear absorption, scattering by produced hadrons, and energy loss in the medium. Hot matter effects that could reduce the observed quarkonium rates such as color screening and thermal activation are then discussed. Possible quarkonium enhancement through coalescence of uncorrelated heavy quarks and antiquarks is also described. Finally, we discuss the capabilities of the LHC detectors to measure heavy quarks and quarkonia as well as the Monte Carlo generators used in the data analysis.Comment: 126 pages Latex; 96 figures included. Subgroup report, to appear in the CERN Yellow Book of the workshop: Hard Probes in Heavy Ion Collisions at the LHC.

    BACKGROUND: Coexistent lung cancer and pulmonary tuberculosis is an urgent problem of thoracic surgery presenting a challenging task for diagnosis and surgical treatment. MATERIALS AND METHODS: From 1990 to 2005, 2218 patients with lung cancer underwent surgical treatment in Department of Thoracic Surgery and Oncology, Institute of Oncology, Vilnius University. In 46 (2.1%) patients coexistence of lung cancer and tuberculosis was found. Central lung cancer was diagnosed in 37 (80.4%) and peripheral – in 9 (19.6%) patients. Epidermoid cancer was diagnosed in 24 (52.2%) patients, adenocarcinoma – in 10 (21.7%) and adenoepidermoid carcinoma – in 12 (26.1%) patients. Stage I cancer was diagnosed in 12 (26.1%), stage II – in 11 (23.9%), and stage IIIA – in 23 (50%) patients. RESULTS: Pneumonectomy was performed in 18 (39.2%), lobectomy in 10 (21.7%), bilobectomy in 10 (21.7%), segmentectomy in 8 (17.4%) patients. Postoperative surgical complications were observed in 9 (19.5%) patients, non-surgical complications occurred in 19 patients (41.3%). Six patients (13.04%) died. Combined treatment was applied to 23 (50%) patients. CONCLUSION: Coexistence of tuberculosis and lung cancer in thoracic surgery is fairly rare. This combination was diagnosed only in 46 cases (2.1%) out of 2218 operated lung cancer patients. Epidermoid carcinoma and stage IIIA disease was diagnosed in 50% of patients. Postoperative surgical complications occurred in 9 patients (19.5%) with lung cancer and tuberculosis. Six patients (13%) died in postoperative period. Surgery is the method of choice in treatment of combination of tuberculosis and lung cancer. Median survival of these patients was 28 ± 2 months

    Two-dimensional discrete wavelet analysis of multiparticle event topology in heavy ion collisions

    Full text link
    The event-by-event analysis of multiparticle production in high energy hadron and nuclei collisions can be performed using the discrete wavelet transformation. The ring-like and jet-like structures in two-dimensional angular histograms are well extracted by wavelet analysis. For the first time the method is applied to the jet-like events with background simulated by event generators, which are developed to describe nucleus-nucleus collisions at LHC energies. The jet positions are located quite well by the discrete wavelet transformation of angular particle distribution even in presence of strong background.Comment: 6 pages, 6 figure

    Partial-wave analysis of the eta pi+ pi- system produced in the reaction pi-p --> eta pi+ pi- n at 18 GeV/c

    Full text link
    A partial-wave analysis of 9082 eta pi+ pi- n events produced in the reaction pi- p --> eta pi+ pi- n at 18.3 GeV/c has been carried out using data from experiment 852 at Brookhaven National Laboratory. The data are dominated by J^{PC} = 0^{-+} partial waves consistent with observation of the eta(1295) and the eta(1440). The mass and width of the eta(1295) were determined to be 1282 +- 5 MeV and 66 +- 13 Mev respectively while the eta(1440) was observed with a mass of 1404 +- 6 MeV and width of 80 +- 21 MeV. Other partial waves of importance include the 1++ and the 1+- waves. Results of the partial wave analysis are combined with results of other experiments to estimate f1(1285) branching fractions. These values are considerably different from current values determined without the aid of amplitude analyses.Comment: 22 pages, 8 figure

Some figures modified in chapter 7 (off-chemical equilibrium photon rates) and comparison with PHENIX data adde

    Observation of exotic meson production in the reaction πpηπp \pi^{-} p \to \eta^{\prime} \pi^- p at 18 GeV/c

    Full text link
    An amplitude analysis of an exclusive sample of 5765 events from the reaction πpηπp\pi^{-} p \to \eta^{\prime} \pi^- p at 18 GeV/c is described. The ηπ\eta^{\prime} \pi^- production is dominated by natural parity exchange and by three partial waves: those with JPC=1+,2++,J^{PC} = 1^{-+}, 2^{++}, and 4++4^{++}. A mass-dependent analysis of the partial-wave amplitudes indicates the production of the a2(1320)a_2(1320) meson as well as the a4(2040)a_4(2040) meson, observed for the first time decaying to ηπ\eta^{\prime}\pi^-. The dominant, exotic (non-qqˉ)q\bar{q}) 1+1^{-+} partial wave is shown to be resonant with a mass of 1.597±0.0100.010+0.0451.597 \pm 0.010^{+0.045}_{-0.010} GeV/c^2 and a width of 0.340±0.040±0.0500.340 \pm 0.040 \pm 0.050 GeV/c^2 . This exotic state, the π1(1600)\pi_1(1600), is produced with a tt dependence which is different from that of the a2(1320)a_2(1320) meson, indicating differences between the production mechanisms for the two states.Comment: 5 pages with 4 figure
