Cross-relaxation and phonon bottleneck effects on magnetization dynamics in LiYF4:Ho3+
Frequency and dc magnetic field dependences of dynamic susceptibility in
diluted paramagnets LiYF:Ho have been measured at liquid helium
temperatures in the ac and dc magnetic fields parallel to the symmetry axis of
a tetragonal crystal lattice. Experimental data are analyzed in the framework
of microscopic theory of relaxation rates in the manifold of 24
electron-nuclear sublevels of the lowest non-Kramers doublet and the first
excited singlet in the Ho ground multiplet split by the crystal
field of S symmetry. The one-phonon transition probabilities were computed
using electron-phonon coupling constants calculated in the framework of
exchange charge model and were checked by optical piezospectroscopic
measurements. The specific features observed in field dependences of the in-
and out-of-phase susceptibilities (humps and dips, respectively) at the
crossings (anti-crossings) of the electron-nuclear sublevels are well
reproduced by simulations when the phonon bottleneck effect and the cross-spin
relaxation are taken into account

The paper discusses problems of strategic planning and management in the Russian Federation, primarily the lack of comprehensive methodological approaches to strategic planning in regions and cities, especially to selecting priorities of their socio-economic development. The conceptual framework of this research is based on strategic management theory and theories of regional and spatial economics. The paper also reviews Russian and international approaches to the concept of strategy and to strategic planning and management in general. The author analyses the key strategic planning documents of million-plus Russian cities, such as Perm, Novosibirsk, Ekaterinburg, Kazan, and others. These cities are a major driving force behind the countryβs economic development. In the paper, they are divided into three groups depending on the time period of their strategies. The conclusion is made that the optimal choice of priorities and adequate control over the implementation of these strategies are crucial for their success. In other words, it is necessary to improve the currently existing mechanisms of strategic planning and management to ensure more efficient development of urban territories. Moreover, most strategies focus only on those processes and phenomena that fall within the jurisdiction of local authorities although it would be much more effective to involve all groups of stakeholders and facilitate their cooperation in achieving common goals of the cityβs development.Π‘ΡΠ°ΡΡΡ ΠΏΠΎΡΠ²ΡΡΠ΅Π½Π° Π°Π½Π°Π»ΠΈΠ·Ρ ΠΏΡΠΎΠ±Π»Π΅ΠΌ ΠΏΡΠΎΡΠ΅ΡΡΠΎΠ² ΡΡΡΠ°ΡΠ΅Π³ΠΈΡΠ΅ΡΠΊΠΎΠ³ΠΎ ΠΏΠ»Π°Π½ΠΈΡΠΎΠ²Π°Π½ΠΈΡ ΠΈ ΡΠΏΡΠ°Π²Π»Π΅Π½ΠΈΡ Π² Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ, ΠΎΠ΄Π½ΠΎΠΉ ΠΈΠ· ΠΊΠΎΡΠΎΡΡΡ

Implementation mechanisms of strategies of socio-economic territorial development: methodological approach
The article analyzes strategic planning and management in Russia. At present the latter can be characterized as lacking a unified methodological approach to devising strategies of territorial socio-economic development, including mechanisms of strategy implementation. Conceptually this study relies on the theory of strategic management, regional and spatial economics, on dialectical, cause-and-effect, and other methods. An overview of approaches to strategies in Russian and international studies is provided. The article also describes the long-term challenges faced by Russian economy at the turn of the millennium and the goals of national development. The main stages of strategic planning are outlined as well as the current state of strategic planning and management. It is shown that strategic planning and management are crucial for the development of territories on all levels (municipal, regional and national). A special emphasis is placed on the case of Ekaterinburg and other large Russian cities and the possibilities of using their experience in other territories. Some recommendations are formulated as to the ways and means of creating mechanisms for implementation of socio-development strategies. The resulting algorithm is shown to be optimal for building strategy implementation mechanisms, which makes this study both theoretically and practically relevant
The algebraic hyperstructure of elementary particles in physical theory
Algebraic hyperstructures represent a natural extension of classical
algebraic structures. In a classical algebraic structure, the composition of
two elements is an element, while in an algebraic hyperstructure, the
composition of two elements is a set. Algebraic hyperstructure theory has a
multiplicity of applications to other disciplines. The main purpose of this
paper is to provide examples of hyperstructures associated with elementary
particles in physical theory.Comment: 13 page
Constraints on Conformal Windows from Holographic Duals
We analyze a beta function with the analytic form of
Novikov-Shifman-Vainshtein-Zakharov result in the five dimensional
gravity-dilaton environment. We show how dilaton inherits poles and fixed
points of such beta function through the zeros and points of extremum in its
potential. Super Yang-Mills and supersymmetric QCD are studied in detail and
Seiberg's electric-magnetic duality in the dilaton potential is explicitly
demonstrated. Non-supersymmetric proposals of similar functional form are
tested and new insights into the conformal window as well as determinations of
scheme-independent value of the anomalous dimension at the fixed point are
presented.Comment: Fig. 5b is corrected to match the discussion in the tex
