Currently, Dr. Antonov is the head of the Department of Higher Mathematics, St. Petersburg Polytechnic University. His research interests are focused on creating mathematical models of energy processes in complex biological and technical systems. These models are based on both the classical equations of heat and mass transfer (Antonov V 2008 Heat Transfer research) and fractal analysis and chaos theory (Antonov V, Zagaynov A 2015, ISAST). The cooperation with leading scientific centers of Russia and other countries are important in this work. This makes it possible to verify in practice the results of a numerical analysis of real processes. The developed models are successfully used to analyze the circulatory system, physical processes with high energy density, prevent flood situations, etc. Dr. Antonov is a participant and organizer of international conferences (Russia, Italy, Spain, Great Britain, Portugal, etc.).

Abstract:

Statement of the Problem: An important direction of modern research is the substance unique properties in the field of supercritical parameters including the possibility of these states sharp decay. To obtain supercritical fluids, it is necessary to create a high energy density in the substance. It can be achieved when using pulsed energy injection into a substance with maximum peak power. A possible method for creating the required energy density in metals is an electric explosion. It provides a high current density of 108 A/cm² and a high specific power of Joule heating of a substance. But in this case, the requirements for the electrical circuit power system are extremely high. They can be reduced by using a spatial concentration of power in the substance. This may be the magnetic implosion of cylindrical metal shells on the axis of the certain configuration. The interaction of compressible shell with a cylindrical target located on the axis of the system is also of interest. These methods are applicable to obtain powerful megajoule pulses of soft x-ray radiation and magnetic field pressure of the megabar range. The energy storage and multi-stage energy switching systems create mega-ampere current pulses with a high slew rate. In such a linear system, the kinetic energy of a compressible shell collides with a target and transforms into the energy of a converging cylindrical shock wave. As a result, it becomes possible to exacerbate the radiation pulse and pressure in the shock wave. The calculation analysis of the process is based on the one-dimensional two-temperature magneto hydrodynamic radiation model, in which the physical processes are self-consistent.  We formulate the requirements for a laboratory energy source to establish the characteristics of a current pulse flowing through a conductive cylindrical shell and its dimensions.

Abstract:

Designing and utilization of novel materials for manufacturing of the sources of coherent irradiation is currently a vast interdisciplinary area, which spans various theoretical and fundamental aspects of laser physics, condensed matter physics, nanotechnology, chemistry as well information science. Physical realization of corresponding devices requires the ability to manipulate the group velocity of propagation of electromagnetic pulses, which is accomplished by the use of the so-called polaritonic crystals. The latter represent a particular type of photonic crystals featured by a strong coupling between quantum excitations in a medium (excitons) and optical fields [1-3].

We considered 1D and 2D polaritonic crystals as a topologically ordered systems – arrays of coupled microcavities containing quantum dots. It is of substantial interest to investigate electromagnetic excitations in a non-ideal one-dimensional microcavity lattice subjected to a uniform elastic stress [4,5]. The one-sublattice array of identical cavities contains randomly embedded quantum dots of two types. Moreover, these microcavity-resonators are also randomly removed at distances between the nearest neighbors. In order to calculate polaritonic spectrum of such a system we shall adopt the virtual crystal approximation, which is based on diagonalization of the averaged Hamiltonian. The peculiarities of polariton spectrum in the 1D and 2D lattices of microcavities caused by the presence of the structure defects and uniform elastic deformation (described by tensor ) of the micropores array with quantum dots are studied. In this case, the random location of pores containing quantum dots is determined by concentrations in composition and position respectively,. The presence of deformation and of structural defects may lead to an increase of the effective mass of corresponding excitations and therefore to a decrease of their group velocity. The results of numerical calculation performed on the basis of the constructed model contribute to modeling of the new class of functional materials – photonic crystalline system constituted of couple microcavities..

Job Beckers is Assistant Professor within the Elementary Processes in Gas Discharges group at Eindhoven University of Technology (TU/e). His research focuses on discovering how nanometer- to micrometer-scale particles interact with plasmas on the most fundamental level. The researched plasmas include electrically generated discharges and plasmas induced by highly energetic photons and electrons. 

Abstract:

Today’s newest photolithography tools operate using photons in the Extreme Ultraviolet (EUV) wavelength range and at low hydrogen gas pressures, typically 1-10 Pa. Everywhere in the machine where these highly energetic photons travel, a peculiar transient background plasma is induced. The formation of such plasma is the results of the partial photoionization of the background gas by the photons used. Additionally, the created free electrons have sufficient energy to continue the ionization of the background gas even further by means of electron impact ionization.

The inevitable presence of EUV-induced plasmas in lithography tools may have significant impact on the EUV optics used in these systems in terms of contamination, cleaning and life-time issues.

In this contribution we focus on our research efforts probing the dynamics of the two most dominant species in plasmas, i.e. electrons and positive ions.

The electrons have extensively been probed using microwave radiation in the so-called Microwave Cavity Resonant Spectroscopy (MCRS) diagnostic. Our latest improvements with respect to MCRS enabled to monitor free electron dynamics in the plasma temporally resolved (~100 ns resolution) and with a high resolution (low detection limit of 10¹⁰ m^-3). Utilizing multiple resonant modes, this diagnostic can be used to spatially resolve the electron density profile and to act as a beam monitor for pointing stability and beam power.

The fluxes and energy distributions of ions towards plasma-facing surfaces have been characterized temporally resolved using a retarding field energy analyzer (RFEA) and an electrostatic quadrupole plasma analyzer (EQP).    

This contribution shows the current state-of-the-art knowledge level regarding EUV-induced plasmas as well as some latest results and our research plans for the future.

AKALawsofRelativity almost everything we do today is centred on Time, we have ultimately place data’s the most intrinsic value of life. Also been considered is the quality of relativism where by every thing we see is relative toanother, andthis is where the concept of time comes from. Basically, we can't define what life is with out having the understanding of death, and we can’t say what grow this without making reference to the last state or the organism, and we can't say what moves

Abstract:

Breast cancer known as the heterogeneous disease and frequently prolonged for several year with potential risks in metastasizing to other organs in the body remains one of the leading causes of cancer related death in women worldwide that requires a complex combination of solutions involving interference in the regulation of the gene expression and other complicated clinical treatments. ASMT is a key determinant of the levels of released melatonin. Though melatonin has been shown to exhibit anti-cancer activity and prevents endocrine resistance in breast cancer, the role of ASMT in breast cancer progression remains unclear. The necessity to build a prognosis model to predict its spread to other sites is extremely urgent. So herein, we conducted this research to seeking the gene signature related to the metastasis of Breast cancer to Lung to improve the accuracy of current diagnostic methods at the earliest stages, and importantly further investigate the significance of ASMT expression in human breast cancer and its relationship to survival outcomes in order to increase the survival rate for patients.

Abstract:

Different nominals of CdO-P₂O₅-V₂O₅ glass systems have prepared via conventional melt quenching technique. The main purpose of the present research is how to improve the phosphate network by the cadmium and vanadium content. Vanadium oxide may work as a glass modifier or a glass former depending on the glass composition and the vanadium ratio. The presence of the CdO and V₂O₅ makes these glasses act as semiconductor materials through lowering the band gap and also enhances the non-linear optical behavior. Therefore, the replacement of P₂O₅ and CdO by vanadium pentoxide is examined. Structural investigation, such as density, molar volume, and the other related parameters estimated in terms of the vanadium content. The glass morphology of the present system was detected by scanning electron microscopy. Raman and Infrared spectroscopies used to detect the structural building units of the prepared glass system. Optical and nonlinear optical properties were determined and calculated as a function of vanadium content. The correlation between the structural changes and the optical properties was discussed in terms of the non-bridging oxygens linkage.
