The comparative evaluation of the operational performance of the economies of constituent entities of the Russian Federation

The article consideres the existing practice of the comparative assessment of effectiveness of the economies of constituent entities of the Russian Federation, reveals its shortcomings, and the factors causing them, factors causing them, including the shortcomings of the system and indicators of state statistical reporting and methods for their determination, as well as the consequences of these shortcomings in the system of internal economic and social-labor relations. The authors ’proposals are based on the following: adopting, as a generalized indicator of the economic efficiency of the functioning of the economies of administrative-territorial entities of the country, the indicator of gross domestic income generated in their territories, regardless of which of them are registered; changes in the basic provisions for determining in statistical accounting the volumes of the gross domestic product and gross income, excluding from their volumes the cost of services, that do not represent in their content the newly created value

ABOUT THE APPROACH AND METHOD OF DETERMINING THE VALUE OF ROYALTIES FOR THE DEVELOPMENT OF MINERALS

All business entities, regardless of their form of ownership, must obey established rules, when paying for the right to use licenses for inventions, renting films, publishing books, products, patents, innovations. The calculation of the amount of payment is carried out in accordance with the bilateral agreement. Calculating royalties, based on profits earned by an enterprise, has certain disadvantages. Many of the most diverse factors affect the volume of profit. The author’s approach and the method of determining the value of royalties for the development of mineral resources have been explained in the article. Their basis consists of: determining the value of economic rent as a result of the extraction and sale of mineral resources; ensuring, that mining companies receive income on their production capital at a level not lower than the average for the country’s economy as a whole

Feasibility and challenges of performing magnetoencephalography experiments in children with arthrogryposis multiplex congenita

Arthrogryposis multiplex congenita (AMC) has recently drawn substantial attention from researchers and clinicians. New effective surgical and physiotherapeutic methods have been developed to improve the quality of life of patients with AMC. While it is clear that all these interventions should strongly rely on the plastic reorganization of the central nervous system, almost no studies have investigated this topic. The present study demonstrates the feasibility of using magnetoencephalography (MEG) to investigate brain activity in young AMC patients. We also outlined the general challenges and limitations of electrophysiological investigations on patients with arthrogryposis. We conducted MEG recordings using a 306-channel Elekta Neuromag VectorView system during a cued motor task performance in four patients with arthrogryposis, five normally developed children, and five control adults. Following the voice command of the experimenter, each subject was asked to bring their hand toward their mouth to imitate the self-feeding process. Two patients had latissimus dorsi transferred to the biceps brachii position, one patient had a pectoralis major transferred to the biceps brachii position, and one patient had no elbow flexion restoration surgery before the MEG investigation. Three patients who had undergone autotransplantation prior to the MEG investigation demonstrated activation in the sensorimotor area contralateral to the elbow flexion movement similar to the healthy controls. One patient who was recorded before the surgery demonstrated subjectively weak distributed bilateral activation during both left and right elbow flexion. Visual inspection of MEG data suggested that neural activity associated with motor performance was less pronounced and more widely distributed across the cortical areas of patients than of healthy control subjects. In general, our results could serve as a proof of principle in terms of the application of MEG in studies on cortical activity in patients with AMC. Reported trends might be consistent with the idea that prolonged motor deficits are associated with more difficult neuronal recruitment and the spatial heterogeneity of neuronal sources, most likely reflecting compensatory neuronal mechanisms. On the practical side, MEG could be a valuable technique for investigating the neurodynamics of patients with AMC as a function of postoperative abilitation

Torsional Magnetic Oscillations in Type I X-Ray Bursts

Thermonuclear burning on the surface of a neutron star causes the expansion of a thin outer layer of the star, $\Delta R(t)$. The layer rotates slower than the star due to angular momentum conservation. The shear between the star and the layer acts to twist the star's dipole magnetic field giving at first a trailing spiral field. The twist of the field acts in turn to `torque up' the layer increasing its specific angular momentum. As the layer cools and contracts, its excess specific angular momentum causes it to {\it rotate faster} than the star which gives a leading spiral magnetic field. The process repeats, giving rise to torsional oscillations. We derive equations for the angular velocity and magnetic field of the layer taking into account the diffusivity and viscosity which are probably due to turbulence. The magnetic field causes a nonuniformity of the star's photosphere (at the top of the heated layer), and this gives rise to the observed X-ray oscillations. The fact that the layer periodically rotates faster than the star means that the X-ray oscillation frequency may ``overshoot'' the star's rotation frequency. Comparison of the theory is made with observations of Chakrabarty et al. (2003) of an X-ray burst of SAX J1808.4-3658.Comment: 7 pages, 6 figures, accepted for publication in the Ap
