Dialectics of Efficient Change Management in the Regional Social Systems
The research has placed emphasis on the role of the social infrastructure sectors, providing social services, which facilitate human potential development in a modern state. Theoretical positions of the scientist considering the nature of social benefits and necessity of the government support for the social sphere has been summarized in the article. The state of the Russian social infrastructure sectors has been considered and the analysis of their performance compared to these of the social infrastructure sectors in other countries has been conducted in the research work. Taking into consideration the performance ratings of the effectiveness of the national education systems, the countries around the world concerning the effectiveness of the health system, the countries around the world concerning the social development level in 2014, the authors have proposed the conceptual approach that makes it possible to consider the correlation and interrelation of the level of the government financing of the social sphere and the dynamics of the contribution of social infrastructure sectors in the development of the human capital, ensuring the gross domestic product increase. The necessity of making innovative changes in the socio-economic systems of the social infrastructure sectors, to improve their performance, taking into account the results obtained, in the first place, in health care, has been wellgrounded and theoretical approaches to the changes management in the socio-economic systems has been studied in the article. The theoretical approaches to the changes management in the socio-economic systems have been studied by the authors. Based on the conducted studies and the formed theoretical basis for improving the level of changes management in open socio-economic systems, for the purpose of development of the theoretical and methodological approaches to changes management as applied to health care sphere, optimization model of management of health care organizations by way of ranking of manageable and unmanageable changes has been proposed. The possibility of using management optimization by way of ranking of manageable and unmanageable changes in the health care management at different levels has been confirmed with high-performance indicators at the micro-, meso- and macro levels in the sector, by the example of implementation of the national project “Health” and innovative organizational changes facilitating the return to work of patients of the working age, which are involved in the gross domestic product formation in the city of Yekaterinburg.The article has been prepared with the support of the Russian Science Foundation grant No. 14-18-00456 “Support of geoecosocioeconomic approach to development of strategic nature resources capacity of the low-studied northern territories within the investment project “Arctic — Central Asia”
Charmed Hadrons from Strangeness-rich QGP
The yields of charmed hadrons emitted by strangeness rich QGP are evaluated
within chemical non-equilibrium statistical hadronization model, conserving
strangeness, charm, and entropy yields at hadronization.Comment: 6 pages, 2 figures SQM 2006; the same as J. Phys. G in pres
Peltier effect in normal metal-insulator-heavy fermion metal junctions
A theoretical study has been undertaken of the Peltier effect in normal metal
- insulator - heavy fermion metal junctions. The results indicate that, at
temperatures below the Kondo temperature, such junctions can be used as
electronic microrefrigerators to cool the normal metal electrode and are
several times more efficient in cooling than the normal metal - heavy fermion
metal junctions.Comment: 3 pages in REVTeX, 2 figures, to be published in Appl. Phys. Lett.,

One-dimensional structures behind twisted and untwisted superYang-Mills theory
We give a one-dimensional interpretation of the four-dimensional twisted N=1
superYang-Mills theory on a Kaehler manifold by performing an appropriate
dimensional reduction. We prove the existence of a 6-generator superalgebra,
which does not possess any invariant Lagrangian but contains two different
subalgebras that determine the twisted and untwisted formulations of the N=1
superYang-Mills theory.Comment: 12 pages. Final version to appear in Lett. Math. Phys. with improved
notation and misprints correcte
On the equations of the analytical dynamics of the quasi-3D plate theory of I. N. Vekua type and some their solutions
The plate theory of Nth order is constructed on the background of the Lagrangian variational formalism of analytical dynamics of continuum systems and the dimensional reduction approach of I. N. Vekua – A. A. Amosov. The plate model is defined within the configuration space, the set of field variables, and the Lagrangian density. The field variables are determined by the coefficients of the biorthogonal expansion of the spatial displacement vector field with respect to the dimensionless normal coordinate. The dynamic equations are derived as Lagrange equations of the second kind of the two-dimensional continuum system. The dynamics of the plane elastic layer is considered as an example, the normal wave propagation is described on the basis of refined plate theories of various orders, and the convergence of approximate solutions to the exact solution of the three-dimensional elastodynamics problem is analyzed for different wavenumbers
Rare events – rare attractors; formalization and examples
Analogy between attractors in nonlinear dynamics, called “rare attractors” by M.V. Zakrzhevsky and his colleagues [1] and emergencies, such as natural and technogenic catastrophes as well as downfalls caused by risky economic policies and strategies has been discussed. Examples of rare but technically significant attractors in nonlinear dynamics have been give
Long-distance entanglement and quantum teleportation in XX spin chains
Isotropic XX models of one-dimensional spin-1/2 chains are investigated with
the aim to elucidate the formal structure and the physical properties that
allow these systems to act as channels for long-distance, high-fidelity quantum
teleportation. We introduce two types of models: I) open, dimerized XX chains,
and II) open XX chains with small end bonds. For both models we obtain the
exact expressions for the end-to-end correlations and the scaling of the energy
gap with the length of the chain. We determine the end-to-end concurrence and
show that model I) supports true long-distance entanglement at zero
temperature, while model II) supports {\it ``quasi long-distance''}
entanglement that slowly falls off with the size of the chain. Due to the
different scalings of the gaps, respectively exponential for model I) and
algebraic in model II), we demonstrate that the latter allows for efficient
qubit teleportation with high fidelity in sufficiently long chains even at
moderately low temperatures.Comment: 9 pages, 6 figure
Excitation Energy Dependence of the Exciton Inner Ring
We report on the excitation energy dependence of the inner ring in the
exciton emission pattern. The contrast of the inner ring is found to decrease
with lowering excitation energy. Excitation by light tuned to the direct
exciton resonance is found to effectively suppress excitation-induced heating
of indirect excitons and facilitate the realization of a cold and dense exciton
gas. The excitation energy dependence of the inner ring is explained in terms
of exciton transport and cooling.Comment: 5 pages, 4 figure
