Global characteristics of nucleus-nucleus collisions in an ultrarelativistic domain

The global observable distributions of nucleus-nucleus collisions at a high energy are studied. It is shown that these distributions are sensitive to interaction dynamics and can be used to investigate the evolution of dense nuclear matter. On the LHC energy scale ( square root s/sub NN/=5 TeV in the heavy-ion mode), a central bump over the pseudorapidity plateau in jet quenc

Excitonic ordering in strongly correlated spin crossover systems: induced magnetism and excitonic excitation spectrum

The effects associated with interatomic hoppings of excitons and the excitonic Bose condensate formation in the strongly correlated spin crossover systems are considered in the framework of the effective Hamiltonian for the two-band Kanamori model. The appearance of antiferromagnetic ordering due to the exciton order is found even in the absence of interatomic exchange interaction. The spectrum of excitonic excitations is calculated at various points of the "temperature vs. crystal field" phase diagram. Outside the region of exciton ordering, the spectrum has a gap, which vanishes at the boundary of the exciton condensate phase. The non-uniform spectral weight distribution over the Brillouin zone is found. The role of electron-phonon interaction is discussed as well.Comment: 10 pages, 10 figure

Methodological basis for the development of municipal entity strategy

Strategy development is one of the most important functions of a municipal entity management. In addition to a sound strategic plan, successful development requires an effective mechanism for its implementation. Despite a significant number of scientific studies devoted to the problems of strategizing municipalities, the issues of instrumental and methodological support of the strategic planning process remain insufficiently developed. The set of actions to develop a strategy and its implementation create prerequisites for the formation of strategic management system of a municipal entity. The purpose of the research is to develop and use a new approach to the classifi- cation of methods for the development and implementation of a municipal entity strategy, which is based on the principle of separation of methods in accordance with the tasks of strategic management. As a methodological basis, the study uses a functional approach that provides for the division of the strategic planning process into a number of aggregated functional tasks. Scientific publications and works of foreign and domestic scientists, devoted to the analysis of the formation of strategic prospects for the development of the municipality have been studied. The result of the research is a classification of strategic planning methods, where the main stages of the strategic planning process, the tasks of strategic choice and methods of their solution are put in logical correspondence. The theoretical significance of the research lies in the development of the methodological foundations of the process of strategic management of a municipal formation. Classification of strategic planning methods proposed in the article in accordance with the functional characteristics of the strategic planning stage is of practical importance. The results can be used in subdivisions of a municipal en- tity management system that solve the problems of developing and implementing a strategy, as well as in the educational process when training bachelors in the areas of «Management» and «State and Municipal Administration»
