The genesis of these problems having formed at present has been revealed. It has been shown that the whole complex of problems was generated with the change of the territorial approach to the public management.

    The role of artificial intelligence technologies in long-term socio-economic development and integrated security

    The symbol of the second decade of the 21st century is the renaissance of artificial intelligence technologies. Today, the consequences of introducing such systems are still not fully understood (especially when the results prepared by the neural network are completely incomprehensible to humans, unlike the results of the logical conclusion of an expert system) in the informational and technological processes of modern society, but the question already concerns such issues as the "ethics of machine intelligence", about a person’s readiness to transfer the right to make decisions to artificial intelligence instead of himself. The object of the paper is to study strategic documents that determine the prospects for the development of artificial intelligence technologies, primarily in the largest economies of the world to determine the contours of global socio-economic and technological development. In the framework of the system-structural and institutional approaches, a comparative and conceptual analysis of the strategies of the leading countries in process of development of artificial intelligence was carried out. The mechanisms for implementing the strategic priorities of the most advanced countries are identified and described. Authors noted the intensification of international competition in the field of development and implementation of artificial intelligence technology and, accordingly, the transformation of complex security threats

    Polymer-wrapped reduced graphene oxide/nickel cobalt ferrite nanocomposites as tertiary hybrid supercapacitors: insights from experiment and simulation

    The tertiary hybrid supercapacitor consisting of PEDOT:PSS wrapped reduced graphene oxide/Ni0.5Co0.5Fe2O4 (PGNC) was developed and its supercapacitance performance has been compared with that of the reduced graphene oxide (rGO)/Ni0.5Co0.5Fe2O4 (GNC), carbon nanotube (CNT)/Ni0.5Co0.5Fe2O4 (CNC) and carbon nanotube/reduced graphene oxide/Ni0.5Co0.5Fe2O4 (CGNC). Among all, PGNC exhibits an excellent specific capacitance of 1286 Fg−1 with a capacitance retention of 95% over 6000 cycles at a current density of 0.5 Ag−1. The synergetic effects between rGO, Ni0.5Co0.5Fe2O4 and the PEDOT:PSS polymer result in an increase in the specific surface area and the pore volume, making PGNC an excellent hybrid supercapacitor for energy storage. The enhancement in the specific capacitance of the PGNC nanocomposite is further validated through first-principles density functional theory calculations, which predict an increment in the density of states at the Fermi level of the GNC and CNC nanocomposites compared to the isolated Ni0.5Co0.5Fe2O4 material. The supercapacitance performance of the PGNC nanocomposite is reported for different electrolytes, different stoichiometric ratios of Ni and Co in NixCo1-xFe2O4 and on different substrates

    The effect of the radiation capture of electrons (RCE) by a solid body, non-filled electron states (NES) in a solid body are considered in the paper aiming at the investigation of laws of RCE by a solid body in the range 0 - 6 eV of energies of electrons, the development of methodologies for the obtaining of the information about NES. As a result new laws of RCE by a solid body in the field of small energies of electrons have been determined as well as the excitation threshold of plasmons in silver, the model of the RCE effect by a solid body in energy range 0 - 6 eV. New methodical techniques for the obtaining of the information about NES of a solid body have been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

    Spin-polarized two-electron spectroscopy of surfaces

    No full text
    This book presents developments of techniques for detection and analysis of two electrons resulting from the interaction of a single incident electron with a solid surface. Spin dependence in scattering of spin-polarized electrons from magnetic and non-magnetic surfaces is governed by exchange and spin-orbit effects. The effects of spin and angular electron momentum are shown through symmetry of experimental geometries: (i) normal and off normal electron incidence on a crystal surface, (ii) spin polarization directions within mirror planes of the surface, and (iii) rotation and interchange of detectors with respect to the surface normal. Symmetry considerations establish relationships between the spin asymmetry of two-electron distributions and the spin asymmetry of Spectral Density Function of the sample, hence providing information on the spin-dependent sample electronic structure. Detailed energy and angular distributions of electron pairs carry information on the electron-electron interaction and electron correlation inside the solid. The “exchange – correlation hole” associated with Coulomb and exchange electron correlation in solids can be visualized using spin-polarized two-electron spectroscopy. Also spin entanglement of electron pairs can be probed. A description of correlated electron pairs generation from surfaces using other types of incident particles, such as photons, ions, positrons is also presented.

    A novel method of ESR oscillating magnetization value determination in strongly correlated metals

    No full text
    We propose a powerful method of direct measurement of oscillating magnetization by the electron spin resonance, based on dependence of resonant conditions on geometry of the experiment. Theoretical consideration of the matter leads to a simple expression for oscillating magnetization. Approbation of this method is implemented by means of cavity ESR spectrometer (60 GHz) on two diverse metallic systems, where static magnetization at the resonance field varies by an order of magnitude. Quantitative values of oscillating magnetization (905 G for EuB6 at T = 4.2 K and 94 G for CeB6 at T = 1.8 K) are in appropriate agreement with the one obtained by the other methods

    Investigation of the behaviour of the Sherman function for elastic electron scattering from Kr and Xe

    No full text
    We have investigated in detail certain rich structures in the Sherman function S arising when spin-polarized electrons are elastically scattered from the heavy noble gases, krypton and xenon. These structures exhibit large magnitudes which span several degrees of the scattering angle and change significantly as the incident electron energy varies. We follow the evolution of these structures as a function of energy both theoretically and experimentally and compare with published data
