Психологические проблемы формирования общей системы ценностей: концептуализация социальных функций российской военной интеллигенции
Introduction. The subject of research in the article is the psychological problems of the formation of a system of universal values.Purpose setting. The paper conceptualizes the social functions of the Russian military intelligentsia. It is noted that at present humanity is experiencing a crisis of traditional and classical forms and methods of sociality, starting with the family and ending with the state and the world community.Methodology of the study. The main methods in the work were the system method; historiographical method; comparison and modeling.Results. The lack of fairness and honesty is the main cause of economic and social disruption, which is rapidly progressing. It can be stopped only through the restoration of attention to the common, the creation and cultivation of universal values. Without belittling the importance and significance of local communities, it is necessary to create a common value space. An important condition for this is the agreement on basic values. The author points out that in the most difficult socio-cultural and informational conditions, the system of professional military education and upbringing is faced with the task of forming and developing the personality of a professional military officer, i.e. an officer who possesses not only professional qualities and abilities, knowledge and skills that form his competence, but also a system of values that characterizes him as a defender of the Motherland and an intellectual.Conclusion. As a conclusion, it is substantiated that a universal, humanistically oriented identity based on common moral values can be “cemented” by the intelligentsia, which needs to become a social pillar of justice and solidarity as the highest forms of social community. It is logical that the value system of the intelligentsia will be intelligence as a social existential quality, focused on common moral values, and not just on the professional ethics of particular social groups. At the same time, since the system of military education has remained a kind of “enclave” of the traditional education system, in which the processes of training and education perform an equally important function, it is the military intelligentsia that is able to take on the role of supporting for the rest of the social groups that are traditionally considered to be intellectuals.Введение. Предметом исследования в статье выступают психологические проблемы формирования системы общечеловеческих ценностей. Постановка задачи. В работе осуществляется концептуализация социальных функций российской военной интеллигенции. Отмечается, что в настоящее время человечество переживает кризис традиционных и классических форм и способов социальности, начиная с семьи и заканчивая государством и мировым сообществом.Методика и методология исследования. Основными методами в работе выступили системный метод; историографический метод; сравнение и моделирование.Результаты. Дефицит справедливости и честности является главной причиной экономической и социальной разрухи, которая быстро прогрессирует. Остановить ее можно только путем восстановления внимание к общему, создания и культивирования общих ценностей. Не умаляя значения локальных сообществ, необходимо создавать общее ценностное пространство. Важным условием этого является согласие по поводу базовых ценностей. Автор указывает, что в сложнейших социально-культурных и информационных условиях перед системой профессионального военного образования и воспитания стоит задача формирования и развития личности профессионального военного – офицера, обладающего не только профессиональными качествами и способностями, знаниями, умениями и навыками, образующими его компетентность, но и системой ценностей, характеризующей его как защитника Родины и интеллигента.Выводы. В качестве вывода обосновывается, что общую, гуманистически ориентированную идентичность, основанную на общечеловеческих моральных ценностях, может «сцементировать» интеллигенция, которой необходимо стать социальной опорой справедливости и солидарности как высших форм социальной общности. Логично, что системой ценностей интеллигенции станет интеллигентность как социальное экзистенциальное качество, ориентированное на общие моральные ценности, а не только на профессиональную этику отдельных социальных групп. При этом, поскольку система военного образования осталась своего рода «анклавом» традиционной системы образования, в котором процессы обучения и воспитания выполняют одинаково важную функцию, именно военная интеллигенция способна взять на себя роль опоры для остальных социальных групп, которые традиционно принято относить к интеллигентам
Spatiotemporal imaging of valence electron motion
Electron motion on the (sub-)femtosecond time scale constitutes the fastest response in many natural phenomena such as light-induced phase transitions and chemical reactions. Whereas static electron densities in single molecules can be imaged in real space using scanning tunnelling and atomic force microscopy, probing real-time electron motion inside molecules requires ultrafast laser pulses. Here, we demonstrate an all-optical approach to imaging an ultrafast valence electron wave packet in real time with a time-resolution of a few femtoseconds. We employ a pump-probe-deflect scheme that allows us to prepare an ultrafast wave packet via strong-field ionization and directly image the resulting charge oscillations in the residual ion. This approach extends and overcomes limitations in laser-induced orbital imaging and may enable the real-time imaging of electron dynamics following photoionization such as charge migration and charge transfer processes
Three-particle States in Nonrelativistic Four-fermion Model
On a nonrelativistic contact four-fermion model we have shown that the simple
Lambda-cut-off prescription together with definite fine-tuning of the Lambda
dependency of "bare"quantities lead to self-adjoint semi-bounded Hamiltonian in
one-, two- and three-particle sectors. The fixed self-adjoint extension and
exact solutions in two-particle sector completely define three-particle
problem. The renormalized Faddeev equations for the bound states with Fredholm
properties are obtained and analyzed.Comment: 9 pages, LaTex, no figure
Measurement of air fluorescence light yield induced by an electromagnetic shower
For most of the Ultra High Energy Cosmic Ray (UHECR) experiments and projects (HiRes, AUGER, TA, JEM-EUSO, TUS,...), the detection technique of Extensive Air Showers (EAS) is based, at least, on the measurement of the air fluorescence induced signal. The knowledge of the Fluorescence Light Yield (FLY) is of paramount importance for the UHECR energy reconstruction. The MACFLY experiment was designed to perform such FLY measurements. In this paper we will present the results of dry air FLY induced by 50 GeV electromagnetic showers as a function of shower age and as a function of the pressure. The experiment was performed at CERN using an SPS electron test beam line. It is shown that the FLY is proportional to deposited energy in air (E_d) and that the ratio FLY/E_d and its pressure dependence remain constant independently of shower age and more generally independently of the excitation source used (single electron track or air shower).For most of the Ultra High Energy Cosmic Ray (UHECR) experiments and projects (HiRes, AUGER, TA, JEM-EUSO, TUS,...), the detection technique of Extensive Air Showers (EAS) is based, at least, on the measurement of the air fluorescence induced signal.

Streaking strong-field double ionization
Double ionization in intense laser fields can comprise electron correlations,
which manifest in the non-independent emission of two electrons from an atom or
molecule. However, experimental methods that directly access the electron
emission times have been scarce. Here, we explore the application of an
all-optical streaking technique to strong-field double ionization both
theoretically and experimentally. We show that both sequential and
non-sequential double ionization processes lead to streaking delays that are
distinct from each other and single ionization. Moreover, coincidence detection
of ions and electrons provides access to the emission time difference, which is
encoded in the two-electron momentum distributions. The experimental data agree
very well with simulations of sequential double ionization. We further test and
discuss the application of this method to non-sequential double ionization,
which is strongly affected by the presence of the streaking field
Observations of comets C/2002 T7 (LINEAR) and 2P/Encke at Andrushivka
Photometric and spectral observations of C/2002 T7 (LINEAR) and 2P/Encke were made with the Zeiss-600 telescope at the Andrushivka Astronomical Observatory in November 2003. CCD imaging of the comets was carried out with narrowband HB filters CN, RC, and BC. The total number of CN molecules, gas production rate for CN, and Afρ value for the dust coma were obtained. The optical spectra of Comet C/2002 T7 (LINEAR) were obtained and reduced for the wavelength range 4200–7300 Å. The reddening gradient is derived for th
Probing multiphoton light-induced molecular potentials
The strong coupling between intense laser fields and valence electrons in molecules causes distortions of the potential energy hypersurfaces which determine the motion of the nuclei and influence possible reaction pathways. The coupling strength varies with the angle between the light electric field and valence orbital, and thereby adds another dimension to the effective molecular potential energy surface, leading to the emergence of light-induced conical intersections. Here, we demonstrate that multiphoton couplings can give rise to complex light-induced potential energy surfaces that govern molecular behavior. In the laser-induced dissociation of H2+, the simplest of molecules, we measure a strongly modulated angular distribution of protons which has escaped prior observation. Using two-color Floquet theory, we show that the modulations result from ultrafast dynamics on light-induced molecular potentials. These potentials are shaped by the amplitude, duration and phase of the dressing fields, allowing for manipulating the dissociation dynamics of small molecules
Dark Matter Search Perspectives with GAMMA-400
GAMMA-400 is a future high-energy gamma-ray telescope, designed to measure
the fluxes of gamma-rays and cosmic-ray electrons + positrons, which can be
produced by annihilation or decay of dark matter particles, and to survey the
celestial sphere in order to study point and extended sources of gamma-rays,
measure energy spectra of Galactic and extragalactic diffuse gamma-ray
emission, gamma-ray bursts, and gamma-ray emission from the Sun. GAMMA-400
covers the energy range from 100 MeV to ~3000 GeV. Its angular resolution is
~0.01 deg(Eg > 100 GeV), and the energy resolution ~1% (Eg > 10 GeV). GAMMA-400
is planned to be launched on the Russian space platform Navigator in 2019. The
GAMMA-400 perspectives in the search for dark matter in various scenarios are
presented in this paperComment: 4 pages, 4 figures, submitted to the Proceedings of the International
