- ПубликацияТолько метаданныеDetecting Rare J/psi -> mu(+)mu(-) Events in the CBM Experiment(2020) Derenovskaya, O. Y.; Ablyazimov, T. O.; Ivanov, V. V.; Russov, Y. V.; Иванов, Виктор ВладимировичA simple and efficient trigger for selecting the rare J/psi -> mu(+)mu(-) events in the CBM experiment is proposed. The trigger fully relies on the signals from coordinate detectors of the MUCH muon system.
- ПубликацияТолько метаданныеZn-CysHis Protein Factor Families: Role of Electrostatic Interaction of Zn-Domains in Factor Functions(2020) Chirgadze, Y. N.; Ivanov, V. V.; Иванов, Виктор ВладимировичThe large amount of the DNA- and RNA-binding protein regulatory factors contain Zn-domains. Total six Zn-CysHis factor families with different functions were considered. Among them the transcription factors of family PF00096, complex type Zn-Cys2His2, is the most important because it includes over 340.000 members of 365.000 total members listed at present in the Zn-containing factor families. The role of electrostatic potential of Zn-domains in the structure and function of factors from different factor families has been considered. We have shown that the positive electrostatic potential of Zn-domains plays an essential role in forming contact of factors' Zn-domains with DNA/RNA in three protein factor families PF00096, PF12874, and PF09329. While in other three families PF03119, PF08996, and PF01258 Zn-domains do not contact with nucleic acids, and electrostatic interactions do not play a distinctive role, consequently.

- ПубликацияТолько метаданныеAnalysis of the Stability of Choosing the Decommissioning Option for Objects of Atomic Energy Use(2019) Abakumova, A. S.; Bochkarev, V. V.; Ivanov, V. V.; Kryanev, A. V.; Иванов, Виктор Владимирович; Крянев, Александр Витальевич© 2019, Pleiades Publishing, Ltd. Abstract: The stability of choosing the decommissioning option for objects of atomic energy use (OAEU) is analyzed. An algorithm for studying changes in the factor values due to variations in the OAEU characterization parameters is described. Numerical examples are presented which implement the proposed schemes for calculating indicators, determining the most preferable options of OAEU decommissioning, and analyzing the stability of the decision of choosing the OAEU decommissioning option with possible factor values.
- ПубликацияТолько метаданныеGeometry database for the CBM experiment(2019) Akishina, E. P.; Alexandrov, E. I.; Alexandrov, I. N.; Filozova, I. A.; Ivanov, V. V.; Иванов, Виктор ВладимировичCopyright © 2019 for this paper by its authors. Use permitted under Creative Commons License Attribution 4.0 International (CC BY 4.0).The last improvements and updates of the Geometry Database (Geometry DB) for the CBM (Compressed Baryonic Matter) experiment are described. The geometry DB is an information system that supports the CBM geometry. The main purpose of the Geometry DB is to provide a storage of the CBM geometry and convenient tools for managing geometry modules assembling various versions of the CBM setup as a combination of geometry modules and additional files. There must be functionality to support different versions of the CBM setup. The ability of setup versions is added. A set of corresponding tools, i.e. a graphical user interface (GUI) and an application programming interface (API), was implemented. Users do not always require regular updates of local CBMRoot from the version control system to solve their tasks (such as simulation or reconstruction). The main goal of the new functionality is to automatically select the setup version when loading the geometry corresponding to the current user environment.
- ПубликацияТолько метаданныеAnalysis of the Features of the Network Traffic in the Trunk Channel: Zero Channel(2021) Ivanov, V. V.; Tatarinov, I. I.; Ivanov, V. V.; Kryanev, A. V.; Prikazchikova, A. S.; Иванов, Виктор Владимирович; Крянев, Александр Витальевич© 2021, Pleiades Publishing, Ltd.Abstract: We showed earlier that, when aggregating network traffic measurements, starting from a certain aggregation window, a stable distribution is formed, which is approximated with a high accuracy by a lognormal law. Despite the fact that, in general, the results of network traffic measurements agree with this law, in the region of the small values of traffic intensity and transmission rate of network packets, there is a noticeable discrepancy between this law and the measurements. In this study, we discuss the problem of a peak arising in the low-intensity region during the aggregation of network traffic measurements. Taking into account the location of the peak in question, we called it the “zero channel” (ZC)
- ПубликацияТолько метаданныеReconstruction of Multivariable Functions Under Uncertainty by Means of the Scheme of Metric Analysis(2021) Sevastyanov, L. A.; Udumyan, D. K.; Kryanev, A. V.; Ivanov, V. V.; Крянев, Александр Витальевич; Иванов, Виктор Владимирович© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.The problem of the reconstruction of a multivariable function whose values with chaotic errors are given at a finite number of points is considered in the paper. The problems of this kind arise when solving applied problems in various fields of research, including physics, engineering, economics, etc. We propose a new approach for solving this problem with the help of a metric analysis. The paper gives numerical two examples of the solution of the problem of the reconstruction of multivariable function, demonstrating the effectiveness of the proposed scheme. In the first example, the results of estimating the exact value of the function at the points where the values of the function with errors are known, in the second example, the results of reconstructing the physical characteristics of the core of a nuclear reactor are presented.
