Экспериментальное исследование воздействия адсорбата на формирование рельефа поверхности тонких металлических пленок в сканирующей зондовой микроскопии
Main regularities of the influence of the air adsorbate on the interpretation of images of thin metal films were experimentally determined in the scanning tunneling microscopy (STM). Modification of the surface relief of a thin film of Pt was made in air.Effect of formation of surface structures of 50-100 nm, a cluster of polarized adsorbate molecules by a strong electric field in the electrode gap, was defined. Tunnel voltage and current threshold values of irreversible relief changes was obtained. Technique of local adsorbate removal from the test surface area was developed by pulse contactless interaction of STM electrodes.

Diffusion transport of material sputtered from the surface of the powered electrode in the asymmetric alternating current discharge is theoretically studied. It is shown that amplitudes of the non-stationary component of the sputtered atom (SA) flow densities at the electrodes depend on the discharge frequency and two dimensionless parameters, which are functions of the SA mass, its mean free path length in the background gas and the distance between the electrodes. It is found that diffusion damping of the time-varying component of the SA number density takes place in the discharge volume under certain conditions and their flows at the electrodes can be considered as time-independent.
The book is an introduction to the qualitative theory of dynamical systems on manifolds of low dimension (on the circle and on surfaces). Along with classical results, it reflects the most significant achevements in this area obtained in recent times. The reader of this book need to be familiar only with basic courses in differential equations and smooth manifolds.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.

The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
