Long-range potentials and (n−1)d+ns(n-1)d+ns molecular resonances in an ultracold rydberg gas

We have calculated long-range molecular potentials of the $0_g^{+}$, $0_u^{-}$ and $1_u$ symmetries between highly-excited rubidium atoms. Strong $np+np$ potentials characterized by these symmetries are important in describing interaction-induced phenomena in the excitation spectra of high $np$ Rydberg states. Long-range molecular resonances are such phenomena and they were first reported in S.M. Farooqi {\it et al.}, Phys. Rev. Lett. {\bf 91} 183002. One class of these resonances occurs at energies corresponding to excited atom pairs $(n-1)d+ns$. Such resonances are attributed to $\ell$-mixing due to Rydberg-Rydberg interactions so that otherwise forbidden molecular transitions become allowed. We calculate molecular potentials in Hund's case (c), use them to find the resonance lineshape and compare to experimental results.Comment: 11 pages, 7 figure

Evaluation level of competition in the market for internet trading

© Medwell Journals, 2016.The main competitive advantage of online stores as well as traditional retail stores is the number of visitors and their confidence. Unlike traditional forms of trade online competitors are just a click away from each other. Internet shops can be divided into two categories: retail offlay-new business and purely virtual stores. More recently, the majority of off-line sellers are not interested in the benefits of e-Commerce, so, their sales through the Internet have been dwarfed by the actual turnover. Small and medium-sized off-line company started its business in order to SETIS diversify and expand markets. Recently, however, off-line players are actively entering the electronic market and tend to occupy a leading position on it which leads to increased competition in this market

Economic efficiency of regulating bank debts on the basis of a debt enforcement (arbitrary procedure)

Objective: to determine the problems of settling the overdue debts of banks in arbitration proceedings and ways to solve them. Methods: methods of vertical and horizontal time series analysis, correlation analysis, grouping methods, and abstract-logical method were used in the research.Results: the problem of collecting bad debts of banks within bankruptcy procedures has actually not been studied in the scientific literature. The paper considers the main aspects of modern research in the field of bankruptcy of physical and juridical persons, and emphasizes the need to systematize the practice of settling bank receivables in arbitration courts. The article presents the results of the analysis of the Bank of Russia statistics on the structure of overdue debts of the banking system, as well as the main results of bankruptcy procedures according to the Federal Register.The analysis of operations of one of the largest regional banks allowed identifying and systematizing the main problems of regulation and control of overdue debts, provision for impairment on loans and interest on loans, and stipulated a low efficiency of the bank’s participation in bankruptcy cases.Scientific novelty: the paper systematizes and analyzes the data on the practice of bankruptcy creditors’ participation in bankruptcy proceedings, and formulates the main directions for solving the problems of low efficiency and high costs of participation in such procedures.Practical significance: the research results can be used in the practical activities of banks for managing and settling accounts receivable, including on the basis of judicial recovery, as well as for developing the main directions of the monetary regulation of banking activity

Avalanche dynamics of radio pulsar glitches

We test statistically the hypothesis that radio pulsar glitches result from an avalanche process, in which angular momentum is transferred erratically from the flywheel-like superfluid in the star to the slowly decelerating, solid crust via spatially connected chains of local, impulsive, threshold-activated events, so that the system fluctuates around a self-organised critical state. Analysis of the glitch population (currently 285 events from 101 pulsars) demonstrates that the size distribution in individual pulsars is consistent with being scale invariant, as expected for an avalanche process. The waiting-time distribution is consistent with being exponential in seven out of nine pulsars where it can be measured reliably, after adjusting for observational limits on the minimum waiting time, as for a constant-rate Poisson process. PSR J0537$-$6910 and PSR J0835$-$4510 are the exceptions; their waiting-time distributions show evidence of quasiperiodicity. In each object, stationarity requires that the rate $\lambda$ equals $- \epsilon \dot{\nu} /$, where $\dot{\nu}$ is the angular acceleration of the crust, $$ is the mean glitch size, and $\epsilon\dot{\nu}$ is the relative angular acceleration of the crust and superfluid. There is no evidence that $\lambda$ changes monotonically with spin-down age. The rate distribution itself is fitted reasonably well by an exponential for $\lambda \geq 0.25 {\rm yr^{-1}}$. For $\lambda < 0.25 {\rm yr^{-1}}$, its exact form is unknown; the exponential overestimates the number of glitching pulsars observed at low $\lambda$, where the limited total observation time exercises a selection bias.Comment: Accepted for publication in the Astrophysical Journa

The role of psychosocial factor in rhematoid arthritis and ankylosing spondylitis

The article is devoted to the study of the psychosomatic characteristics of patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). The study has been divided into 3 stages. The purpose of the first stage was to study the leading personality traits and prevailing types of attitude towards the disease in patients with RA and AS. The purpose of the second stage was to study the role of the social factor in RA patients based on the family pattern, to identify the relationship of intra-family problems with the duration and degree of the disease activity, the level of education. The third stage was aimed to demonstrate the effectiveness of biobehavioral therapy for the correction of pain in patients with RA. Material and methods. The contingent study consisted of patients with a reliable diagnosis of rheumatoid RA and AS, stage 1 – 26 patients (20 men, 6 women), stage 2 – 14 patients (11 women, 3 men), stage 3 – 46 women with RA. The patients underwent clinical, laboratory, X-ray examination. Psychological questionnaires and the Health Assessment Questionnaire (HAQ) were used. Results.: Hypochondria, increased anxiety, emotional immaturity, men’s behavioral characteristics in women have been revealed at the first stage of the study. In men with RA, the leading features are hypochondria, emotional immaturity. Types of attitude to the disease in women were: ergopathic 79 %, harmonious 37 %, neurasthenic 32 %; in men: ergopathic 57 %. The significant intercorrelation between the disease duration in women and the ergopathic and harmonious type of attitude toward the disease was found. The second stage of the study allowed the RA group to identify alienation, unwillingness and inability to independently solve family problems. According to the results of the third stage of the study, it was found that the patient’s acquired ability to control the alpha rhythm voluntarily allowed them to control the intensity of the pain syndrome and reduce the need for taking high doses of NSAIDs. A reduction of feelings of helplessness, hopelessness has been achieved. Conclusions. The study revealed psychological and social problems in patients with RA and AS, substantiating an interdisciplinary approach in the management of the patients with the rheumatologist and psychotherapist participation. Modern possibilities of psychotherapy can reduce the pharmacological burden in the treatment process

Impact of institutional factors on forming a social capital of commercial, state and municipal organizations

Objective: to describe the structure of social capital and the influence of institutional factors on its formation in the frame-work of the concept of atomism.Methods: abstract-logical and dialectical methods.Results: the key link of social capital networks is considered to be a person as an atom, the primary subject, who is the owner and user of social capital. The main structural elements of a person as an atom of social capital are highlighted in terms of their interactions with other economic subjects.Scientific novelty: the notion of the atom of social capital is introduced; by describing the key areas of human interactions with other people (exchanging benefits through transactions and changes in the level of trust after each episode of interaction), the following structural elements of social capital were allocated: 1) personality characteristics related to nationality, citizenship, and religion; 2) ancestral and family ties; 3) needs, characteristics of labor activity, property relations, in which people are involved. It is shown that the process of social capital accumulation is limited by formal and informal rules in the form of an institutional environment in which a person lives and works as an atom of social capital.Practical significance: the presented vision of social capital will reduce the level of uncertainty for economic subjects in terms of building interactions with counterparties. The results of the article can be used in the formation of state policy in relation to commercial, state and municipal organizations
