On insertion-deletion systems over relational words

We introduce a new notion of a relational word as a finite totally ordered set of positions endowed with three binary relations that describe which positions are labeled by equal data, by unequal data and those having an undefined relation between their labels. We define the operations of insertion and deletion on relational words generalizing corresponding operations on strings. We prove that the transitive and reflexive closure of these operations has a decidable membership problem for the case of short insertion-deletion rules (of size two/three and three/two). At the same time, we show that in the general case such systems can produce a coding of any recursively enumerable language leading to undecidabilty of reachability questions.Comment: 24 pages, 8 figure

Zinc oxide films obtained by sol-gel method from film-forming solutions

Thin ZnO films on silicon and quartz substrates were obtained from a film-enriched ethanolic solution based on Zn(NO3)2⋅6H2O and salicylic acid. The effect of salicylic acid on the processes occurring in the film-forming solution was studied by IR spectroscopy, proton-magnetic resonance, and viscometry methods. The formation of zinc salicylate nitrate in an ethanol solution is established, where salicylic acid exhibits a monodentate property in the carboxyl group. Thermal formation of zinc oxide was determined by thermal analysis and X-ray diffraction. The analysis of optical and electrophysical characteristics of ZnO films was carried out using spectroscopy, ellipsometry and also a block for measuring the electrophysical properties of thin-film materials. It was found that ZnO films were semiconductors of the electronic type, characterized by an optical band gap of 2.91–3.21eV, a surface resistance of 109–106 Q. and transparency coefficients in the visible spectral range of 0.80–0.96. It was shown that as the thickness of the ZnO films increased the resistance decreased

This event has summarized, analyzed and discussed the interim results, academic outputs and scientific achievements of the Russian Federal Targeted Programme for Research and Development in priority areas of development of the Russian Scientific and Technological Complex for 2014-2020. It contains 75 selected papers from 6 areas considered priority by the Federal programme: computer science, ecology & environment sciences; energy and energy efficiency; life sciences; nanoscience & nanotechnology; and transport & communications. The chapters report the results of the 3-years research projects supported by the Programme and finalized in 2016

Coherent information analysis of quantum channels in simple quantum systems

The coherent information concept is used to analyze a variety of simple quantum systems. Coherent information was calculated for the information decay in a two-level atom in the presence of an external resonant field, for the information exchange between two coupled two-level atoms, and for the information transfer from a two-level atom to another atom and to a photon field. The coherent information is shown to be equal to zero for all full-measurement procedures, but it completely retains its original value for quantum duplication. Transmission of information from one open subsystem to another one in the entire closed system is analyzed to learn quantum information about the forbidden atomic transition via a dipole active transition of the same atom. It is argued that coherent information can be used effectively to quantify the information channels in physical systems where quantum coherence plays an important role.Comment: 24 pages, 7 figs; Final versiob after minor changes, title changed; to be published in Phys.

Kinetics of thermal destruction of highly porous anionexchange resin TOKEM-320Y

Temperature characteristics, stages and thermal effects of the processes occurring during the thermolysis of TOKEM-320Y anion-exchange resin in an atmosphere of air were determined by differential thermal analysis. The activation energies and the orders of reactions of thermal decomposition of the resin were calculated by the Kissinger and Metzger-Horowitz methods using the TG curves obtained at different heating rates of the resin. Models are proposed that most accurately describe the decomposition of TOKEM-320Y in air in the temperature range 25-800 °C

Complex approach in treatment and diagnostics of chronic generalized parodontitis

The paper presents the results of the examination and quality control of patients with type 2 diabetes mellitus and chronic generalized periodontitis in the stage of decompensation in terms of secretion and oral fluid. It was noted that the indicators come to the initial limits in patients simultaneously undergoing treatment for both diseases, while the indicators of the secret have a great diagnostic value.В работе представлены результаты обследования и контроля за качеством лечения пациентов с сахарных диабетом II типа и хронического генерализованного пародонтита в стадии декомпенсации по показателям секрета и ротовой жидкости. Отмечено, что показатели приходят в исходные пределы у пациентов одновременно проходящие курс лечения обоих заболеваний, при этом показатели секрета имеют большую диагностическую ценность

Visual Algebraic proofs for Unknot Detection

A knot diagram looks like a two-dimensional drawing of aknotted rubberband. Proving that a given knot diagram can be untangled(that is, is a trivial knot, called an unknot) is one of the most famousproblems of knot theory. For a small knot diagram, one can try to finda sequence of untangling moves explicitly, but for a larger knot diagramproducing such a proof is difficult, and the produced proofs are hardto inspect and understand. Advanced approaches use algebra, with anadvantage that since the proofs are algebraic, a computer can be usedto produce the proofs, and, therefore, a proof can be produced evenfor large knot diagrams. However, such produced proofs are not easy toread and, for larger diagrams, not likely to be human readable at all.We propose a new approach combining advantages of these: the proofsare algebraic and can be produced by a computer, whilst each part ofthe proof can be represented as a reasonably small knot-like diagram(a new representation as a labeled tangle diagram), which can be easilyinspected by a human for the purposes of checking the proof and findingout interesting facts about the knot diagram
