Tomsk, Russia

Tomsk Polytechnic University in Tomsk, Russia, is the oldest technical university in Russia east of the Urals. The university was founded in 1896 and opened in 1900 as the Tomsk Technological Institute. In 1923, the school was renamed the Siberian Technological Institute and in 1930, the institute was split into five divisions, three of which remained in Tomsk. In 1934, the three institutes in Tomsk reunited to form a new institute that would be named the Tomsk Polytechnic Institute. The university has more than 22,000 current students and has graduated more than 100,000 technical specialists. As of 2014 the rector was Petr S. Chubik. Wikipedia.

The overall strategy of BILAT-RUS 2 puts the three main issues of the Capacities work programme into practice. It will provide input for the EU-Commission on the state of EU-Russian STI cooperation; contribute to coordinate research policies and programmes of European Member States, Associated Countries and the EU-Commission; enhance information collection and dissemination as regards STI between Russia and the EU; raise awareness of researchers in Russia and the EU for cooperation potentials; monitor the existing STI cooperation praxis and facilitate the implementation of a sustainable cooperation support system; analyse the Russian innovation system and provide support for enhanced implementation of R&D results; deliver a feasibility study for a common representation of European scientific institutions in Russia. One of the major success factors is the close continuous dialogue and the coordination of activities with Russian and European authorities, addressing in particular the Ministry of Education and Science of the Russian Federation (MON), responsible Ministries/Agencies in EU Member States and the EU Commission. The individual activities and tasks that are proposed in the work packages of the project cover a wide array of activities. They include general information and awareness raising activities, the maintenance of the established web-portal with data and knowledge bases on STI issues as well as a inventory and analysis of existing cooperation instruments, the preparation of three yearly analytical reports on the state of EU-Russian STI cooperation, the publication of guidelines for better implementation of R&D results, a feasibility study for a common representation of European scientific organisations in Russia, as well as a mobility grant scheme. Also, activities include the establishment of an external quality control body and an Advisory Board.

Ostrogradsky's method allows one to construct Hamiltonian formulation for a higher derivative system. An application of this approach to the Pais-Uhlenbeck oscillator yields the Hamiltonian which is unbounded from below. This leads to the ghost problem in quantum theory. In order to avoid this nasty feature, the technique previously developed in [7] is used to construct an alternative Hamiltonian formulation for the multidimensional Pais-Uhlenbeck oscillator of arbitrary even order with distinct frequencies of oscillation. This construction is also generalized to the case of an N = 2 supersymmetric Pais-Uhlenbeck oscillator. © 2015 The Author.

Conformal many-body mechanics in Newton-Hooke spacetime is studied within the framework of the Lagrangian formalism. Global symmetries and Noether charges are given in a form convenient for analyzing the flat space limit. N = 2 superconformal extension is built and a new class on N = 2 models related to simple Lie algebras is presented. A decoupling similarity transformation on N = 2 quantum mechanics in Newton-Hooke spacetime is discussed. © 2010 Elsevier B.V. All rights reserved.

Recently, Bañados, Silk, and West analyzed a collision of two particles near the horizon of the extremal Kerr black hole and demonstrated that the energy in the center-of-mass frame can be arbitrarily large provided the angular momentum of one of the colliding particles takes a special value. As is known, the vicinity of the extremal Kerr black hole horizon can be viewed as a complete vacuum spacetime in its own right. In this work, we consider a collision of two neutral particles within the context of the near horizon extremal Kerr geometry and demonstrate that the energy in the center-of-mass frame is finite for any admissible value of the particle parameters. An explanation of why the two approaches disagree on the Bañados-Silk-West effect is given. © 2013 American Physical Society.

The review is focused on the latest achievements in the field of plasma-assisted fabrication of biocompatible CaP-based coatings for medical implants with the emphasis on the coatings composition, structure, mechanical and biological performance. The discussed properties of biocompatible CaP coatings have been recently prepared using the most frequently applied plasma-assisted techniques such as plasma spraying (PS), radio-frequency (RF) magnetron sputtering, pulsed laser deposition (PLD), and ion beam-assisted deposition (IBAD). The review shows that plasma-assisted fabrication allows us to prepare dense, homogeneous, pore-free and high adherent biocompatible coatings able to prevent the leaching of toxic ions from metal to the surrounding tissues or rough and porous coatings capable of stimulating osteogenesis of a new bone. The main advantages and limitations of the described techniques of CaP-based coatings fabrication are presented as well as the most important challenges and critical issues are highlighted. © 2011 Elsevier B.V.

Electrons carrying orbital angular momentum (OAM) have recently been discovered theoretically and obtained experimentally, which opens up possibilities for using them in high-energy physics. We consider such a twisted electron moving in the external field of a plane electromagnetic wave and study how this field influences the electron's OAM. Being motivated by the development of high-power lasers, we focus our attention on a classically strong-field regime for which e2A2̄/(me2c 4)≳1. It is shown that, along with the well-known "plane-wave" Volkov solution, the Dirac equation also has the "non-plane-wave" solutions, which possess OAM and spin-orbit coupling and generalize the free-electron's Bessel states. Motion of an electron with OAM in a circularly polarized laser wave reveals a twofold character: the wave-packet center moves along a classical helical trajectory with some quantum transverse broadening (due to OAM) existing even for a free electron. Using the twisted states, we calculate the electron's total angular momentum and predict its shift in the strong-field regime, which is analogous to the well-known shifts of the electron's momentum and mass (and to a less-known shift of its spin) in intense fields. Since the electron's effective angular momentum is conserved in a plane wave, as well as in some more general field configurations, we discuss several possibilities for accelerating nonrelativistic twisted electrons by using focused and combined electromagnetic fields. © 2012 American Physical Society.

The project is aimed at investigation of the novel routes to prepare functional 2D-substrates or 3D-scaffolds with artificial cell-instructive niches for cardiovascular and bone implants using sophisticated plasma- and electron beam-assisted nanofabrication technologies. The projects grand challenges are as follows: 1) Plasma-assisted fabrication of two-dimensional (2D) substrates and three-dimensional (3D) scaffolds of polymers, titanium and shape-memory alloys to control the differentiation of MSCs towards osteogenic and vascular (endothelial) lineages 2) Deterministic nanofabrication of the endothelial cell-targeted surface chemistry, topography and charge of two-dimensional (2D) substrates and three-dimensional (3D) scaffolds for the prevention of thrombosis of polymers, titanium and shape-memory alloys-based materials 3) Control over the hydrophobic nitric oxide groups containing surface chemistry, wettability and charge that prevent the formation of biofilm and adhesion of platelets 4) Differential diagnostics of cell associations and bioengineering constructions in vitro by use of synchrotron radiation 5) The development and studying of the novel 2D-substrates and 3D polymer scaffolds and their behavior in a bio-reactor (via tissue engineering) in vitro by use of dedicated X-ray multiple contrast diagnostics (objective for re-integration phase of the project). Completing the research planned during the PlasmaNanoSmart project it is suggested to obtain new fundamental data on biological response of novel elaborated biocomposites, which will serve further breakthrough in the field of 3D-bioscaffold technologies for regenerative medicine. The cell biochips advanced technology for smart implants carrying artificial niches for MSCs will be developed which allows us to gradually replace bioinert and bioactive materials. This new bioengineering (biomimetical) approach will reduce the medical, social and economic risks for the public (compared to cell therapy).
