Quantum dynamics in canonical and micro-canonical ensembles. Part I. Anderson localization of electrons
The new numerical approach for consideration of quantum dynamics and
calculations of the average values of quantum operators and time correlation
functions in the Wigner representation of quantum statistical mechanics has
been developed. The time correlation functions have been presented in the form
of the integral of the Weyl's symbol of considered operators and the Fourier
transform of the product of matrix elements of the dynamic propagators. For the
last function the integral Wigner- Liouville's type equation has been derived.
The numerical procedure for solving this equation combining both molecular
dynamics and Monte Carlo methods has been developed. For electrons in
disordered systems of scatterers the numerical results have been obtained for
series of the average values of the quantum operators including position and
momentum dispersions, average energy, energy distribution function as well as
for the frequency dependencies of tensor of electron conductivity and
permittivity according to quantum Kubo formula. Zero or very small value of
static conductivity have been considered as the manifestation of Anderson
localization of electrons in 1D case. Independent evidence of Anderson
localization comes from the behaviour of the calculated time dependence of
position dispersion.Comment: 8 pages, 10 figure
Reaction-Diffusion System in a Vesicle with Semi-Permeable Membrane
We study the Schloegl model in a vesicle with semi-permeable membrane. The
diffusion constant takes a smaller value in the membrane region, which prevents
the outflow of self-catalytic product. A nonequilibrium state is stably
maintained inside of the vesicle. Nutrients are absorbed and waste materials
are exhausted through the membrane by diffusion. It is interpreted as a model
of primitive metabolism in a cell.Comment: 8 pages, 6 figure
Creation and Reproduction of Model Cells with Semipermeable Membrane
A high activity of reactions can be confined in a model cell with a
semipermeable membrane in the Schl\"ogl model. It is interpreted as a model of
primitive metabolism in a cell. We study two generalized models to understand
the creation of primitive cell systems conceptually from the view point of the
nonlinear-nonequilibrium physics. In the first model, a single-cell system with
a highly active state confined by a semipermeable membrane is spontaneously
created from an inactive homogeneous state by a stochastic jump process. In the
second model, many cell structures are reproduced from a single cell, and a
multicellular system is created.Comment: 11 pages, 7 figure

Utjecaj dezoksiribonukleinske kiseline na cijepanje proteina proteolitskim fermentima
BuduΔi da je poznato, da nukleinske kiseline utjeΔu na razliΔite fermentativne procese, u ovom je radu ispitano djelovanje dezoksiribonukleinske kiseline (DNK) na proteolitsku aktivnost tripsina. KΠ°ΠΎ supstrati upotrebljeni su razliΔiti kristalni preparati proteina: ovalbumin, serumski albumin i kazein. Ispitivanja su vrΕ‘ena kod vrijednosti ΡΠ, koje su leΕΎale iznad izoelektriΔne toΔke fermenta i supstrata. Proces proteolize praΔen je s pomoΔu spektrofotometra SF-4 ; razlike ekstinkcija (ΔΠ) nanoΕ‘ene su, izraΕΎene u postocima, u grafikonima na ordinate, Π° vrijeme je nanoΕ‘eno na apscise. Rezultati su prikazani na slikama 1, 2 i 3, iz kojih razabiremo, da nazoΔnost DNK inhibira proteolizu. Dalje je ispitano djelovanje prethodne inkubacije, bilo fermenta bilo suptrata s DNK, na proces proteolize. Pokazalo se, da inhibicijaa proteolize nastupa samo kod prethodne inkubacije supstrata s DNK, dakle da DNK utjeΔe na supstrat, Π° ne na ferment. Ispitan je i odnos koncentracija DNK:supstrat, te je ustanovljeno, da i u velikom suviΕ‘ku supstrata prema DNK dolazi do znatne inhibicije proteolize. Pokazalo se i to, da utjecaj na proces proteolize opada onako, kako opada molekularna teΕΎina DNK

To evaluate the microhardness of the coating we used a technique that required the compulsory penetration of the diamond indenter through the nitride layer. It is shown the microhardness of the coating is six times higher than these values for the base material. The reviewed modes of spraying provide the nitride layers formation that imitates completely the gold plating

Social and economic damage from fire substantially reduces the regional macroeconomic indicators. Thus, a complete and objective assessment of fire damage is a necessity. We hypothesise that a comprehensive assessment of fire damage significantly depends on the characteristics of areas and facilities, where the fire occurred. Such comprehensive assessment should necessarily include the ranking of urban areas and consider the characteristics of facilities located there. We noted that areas and facilities with heterogeneous functions are characterised by increased fire damage (partial or complete). We applied analytical research methods, as well as classification, typology and ranking methods. Based on a detailed analysis of domestic and foreign experience in the field of zoning and ranking of areas, we created a classification of facilities and areas for the comprehensive assessment of fire damage. As a result, we constructed a map of Ekaterinburg areas, taking into account the issues of the comprehensive assessment of fire damage. On the example of Ekaterinburg, we analysed atypical conjunctions of facilities and areas and proposed an index for adjusting complex fire damage. We suggested a simple and versatile approach to ranking areas that considers the heterogeneity of facilities and areas. Additionally, we analysed this phenomenon and its impact on the comprehensive assessment of fire damage. A promising direction for further research is the examination of the comprehensive assessment of fire damage in rural areas.Π‘ΡΠ°ΡΡΡ ΠΏΠΎΠ΄Π³ΠΎΡΠΎΠ²Π»Π΅Π½Π° Π² ΡΠΎΠΎΡΠ²Π΅ΡΡΡΠ²ΠΈΠΈ Ρ ΠΠ»Π°Π½ΠΎΠΌ ΠΠΠ Π£ΡΠ°Π»ΡΡΠΊΠΎΠ³ΠΎ ΠΈΠ½ΡΡΠΈΡΡΡΠ° ΠΠΠ‘ ΠΠ§Π‘ Π ΠΎΡΡΠΈΠΈ Π½Π° 2020 Π³ΠΎΠ΄.The article has been prepared in accordance with the Research Plan of the Ural Institute of State Fire Service of EMERCOM of Russia for 2020
Landau Level Crossings and Extended-State Mapping in Magnetic Two-dimensional Electron Gases
We present longitudinal and Hall magneto-resistance measurements of a
``magnetic'' two-dimensional electron gas (2DEG) formed in modulation-doped
ZnCdMnSe quantum wells. The electron spin splitting is
temperature and magnetic field dependent, resulting in striking features as
Landau levels of opposite spin cross near the Fermi level. Magnetization
measurements on the same sample probe the total density of states and Fermi
energy, allowing us to fit the transport data using a model involving extended
states centered at each Landau level and two-channel conduction for spin-up and
spin-down electrons. A mapping of the extended states over the whole quantum
Hall effect regime shows no floating of extended states as Landau levels cross
near the Fermi level.Comment: 10 pages, 4 figures, submitted to Phys. Rev.
Toolkit for Simulation Modeling of Logistics Warehouse in Distributed Computing Environment
We address an important problem of an automation of logistics warehouses simulation modeling in distributed service-oriented computing environments. To this end, we propose new approach for adjusting management system parameters of real warehouse in production use. It is based on the integration of the conceptual, wireframe and service-oriented programming used to develop parameter sweep applications and data analysis in the simulation modeling process. We develop a toolkit for supporting modeling of warehouse logistics. The practical experiments are focused upon the refrigerated warehouse. The developed application demonstrates high efficiency and scalability for optimizing nine criteria to cope with different production demands.The study was supported by the Russian Foundation of Basic Research, projects no. 15-29-07955 and no. 16-07-00931, and Program 1.33P of fundamental research of Presidium RAS, project βDevelopment of new approaches to creation and study of complex models of information-computational and dynamic systems with applicationsβ
