Photography principle, data transmission, and invariants of manifolds

In the present paper we develop the techniques suggested in \cite{ManturovNikonov} and the photography principle \cite{ManturovWan} to open a very broad path for constructing invariants for manifolds of dimensions greater than or equal to 4

Dynamic modeling of multi-regional migration processes: Ural federal district case study

This article presents a dynamic model, that describes the labor force movement dynamics between Russian regions in continues time. The conducted analysis shows that migration model usually doesn't take into account more than two regions of migration and take into account a very limited number of resulting factors. The presented modification our model allows to explain the dynamics of migration processes and their effects on regional economics both for regions of origin and attraction. The results of migration modeling in conditions of a closed system is presented on a graph and makes it possible to trace dependency between salaries levels, total labor force and the number of vacancies and unemployed people in several regions. Further research is planned to develop a model in terms of constructing unemployment and vacancies forecast and to create a model with elements of agent-based modeling to assess the impact of migration networks on the dynamics of inter-regional migration flows. © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

Hard-core Radius of Nucleons within the Induced Surface Tension Approach

In this work we discuss a novel approach to model the hadronic and nuclear matter equations of state using the induced surface tension concept. Since the obtained equations of state, classical and quantum, are among the most successful ones in describing the properties of low density phases of strongly interacting matter, they set strong restrictions on the possible value of the hard-core radius of nucleons. Therefore, we perform a detailed analysis of its value which follows from hadronic and nuclear matter properties and find the most trustworthy range of its values: the hard-core radius of nucleons is 0.30--0.36 fm. A comparison with the phenomenology of neutron stars implies that the hard-core radius of nucleons has to be temperature and density dependent.Comment: 12 pages, 4 figures, references added, typos correcte

The study of the proton-proton collisions at the beam momentum 1628 MeV/c

The detailed investigation of the single pion production reactions $pp\to pn\pi^{+}$ and $pp\to pp\pi^{o}$ at the incident proton momentum 1628 MeV/c has been carried out. The data are analyzed in the framework of the event-by-event maximum likelihood method together with the $pp\to pp\pi^{0}$ data measured earlier in the energy region below 1 GeV. At 1628 MeV/c the largest contributions stem from the $^{3}P_{2}$, $^{3}P_{1}$, $^{3}P_{0}$, $^{1}D_{2}$ and $^{3}F_{2}$ initial partial waves.Comment: 7 pages, 9 figure

Second virial coefficients of light nuclear clusters and their chemical freeze-out in nuclear collisions

Here we develop a new strategy to analyze the chemical freeze-out of light (anti)nuclei produced in high energy collisions of heavy atomic nuclei within an advanced version of the hadron resonance gas model. It is based on two different, but complementary approaches to model the hard-core repulsion between the light nuclei and hadrons. The first approach is based on an approximate treatment of the equivalent hard-core radius of a roomy nuclear cluster and pions, while the second approach is rigorously derived here using a self-consistent treatment of classical excluded volumes of light (anti)nuclei and hadrons. By construction, in a hadronic medium dominated by pions, both approaches should give the same results. Employing this strategy to the analysis of hadronic and light (anti)nuclei multiplicities measured by ALICE at $\sqrt{s_{NN}} =2.76$ TeV and by STAR at $\sqrt{s_{NN}} =200$ GeV, we got rid of the existing ambiguity in the description of light (anti)nuclei data and determined the chemical freeze-out parameters of nuclei with high accuracy and confidence. At ALICE energy the nuclei are frozen prior to the hadrons at the temperature $T = 175.1^{+2.3}_{-3.9}$ MeV, while at STAR energy there is a single freeze-out of hadrons and nuclei at the temperature $T = 167.2 \pm 3.9$ MeV. We argue that the found chemical freeze-out volumes of nuclei can be considered as the volumes of quark-gluon bags that produce the nuclei at the moment of hadronization.Comment: 15 pages, 4 figures, 3 table

Benzyne-mediated rearrangement of 3-(2-pyridyl)-1,2,4-triazines into 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles

The reaction between 5-R-6-R1-3-(2-pyridyl)-1,2,4-triazines and benzyne generated in situ in toluene under reflux results in the formation of 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles 3 in up to 60% yields instead of the expected 3-R-4-R1-1-(2-pyridyl)isoquinolines 2. The crystal structure of product 3c and the proposed mechanism for the formation of 3 are reported. © 2013 Elsevier Ltd. All rights reserved

Фактическая эпидемиологическая эффективность оценки и совершенствования системы обеспечения эпидемиологической безопасности медицинской помощи катетеризированным пациентам

The basis of optimized conventional system of surveillance and control for catheter-related bloodstream infections (CRBI) was priority in detection and risk assessment an infectious complication of puncture catheterization that substantially justified with inclusion of two main components as an addition to the existing system: monitoring of puncture catheterization, which allows to obtain and analyze data on risk factors for infections associated with the catheterization procedure and subsequent manipulations of the device, standardize approaches to working with a venous catheter and improve the diagnosis of CRBI; assessment of ensuring the epidemiological safety of medical care for catheterized patients. Epidemiological efficiency risk-based surveillance, primarily determined to reduce the incidence of CRBI by 1.8 times compared to initially defined real incidence: 12.5‰ (95% CI — CI 11,8–13 2) vs 22.8‰ (95% CI 21,1–24,5) catheterized patients, p=0.0001.Базисом оптимизированной традиционной системы эпидемиологического надзора и контроля катетер-ассоциированных инфекций кровотока (КАИК) стал принцип первоочередности выявления и оценки риска возникновения инфекционного осложнения пункционной катетеризации, что практически оправдано включением двух основных компонентов как дополнение к существующей системе: мониторинг пункционной катетеризации, который позволяет получать и анализировать данные о факторах риска возникновения инфекций, связанных с процедурой катетеризации и последующими манипуляциями по эксплуатации устройства, стандартизировать подходы к работе с венозным катетером и усовершенствовать диагностику КАИК; оценка обеспечения эпидемиологической безопасности оказания медицинской помощи катетеризированным пациентам. Эпидемиологическая эффективность риск-ориентированного эпидемиологического надзора, в первую очередь, определялась по снижению уровня заболеваемости КАИК в 1,8 раза по сравнению с исходно определенным реальным уровнем заболеваемости: 12,5‰ (95% доверительный интервал — ДИ 11,8–13,2) vs 22,8‰ (95% ДИ 21,1–24,5) катетеризированных пациентов, p=0,0001

Strangeness dynamics and transverse pressure in relativistic nucleus-nucleus collisions

We investigate hadron production as well as transverse hadron spectra from proton-proton, proton-nucleus and nucleus-nucleus collisions from 2 $A\cdot$GeV to 21.3 $A\cdot$TeV within two independent transport approaches (HSD and UrQMD) that are based on quark, diquark, string and hadronic degrees of freedom. The comparison to experimental data on transverse mass spectra from $pp$, $pA$ and C+C (or Si+Si) reactions shows the reliability of the transport models for light systems. For central Au+Au (Pb+Pb) collisions at bombarding energies above $\sim$ 5 A$\cdot$GeV, furthermore, the measured $K^{\pm}$ transverse mass spectra have a larger inverse slope parameter than expected from the default calculations. We investigate various scenarios to explore their potential effects on the $K^\pm$ spectra. In particular the initial state Cronin effect is found to play a substantial role at top SPS and RHIC energies. However, the maximum in the $K^+/\pi^+$ ratio at 20 to 30 A$\cdot$GeV is missed by ~40% and the approximately constant slope of the $K^\pm$ spectra at SPS energies is not reproduced either. Our systematic analysis suggests that the additional pressure - as expected from lattice QCD calculations at finite quark chemical potential $\mu_q$ and temperature $T$- should be generated by strong interactions in the early pre-hadronic/partonic phase of central Au+Au (Pb+Pb) collisions.Comment: 20 pages, 15 figures, Phys.
