THE PHENOMENON OF VIRTUAL IDENTITY: THE CONTEMPORARY CONDITION OF THE PROBLEM
Introduction. Modern society is characterized by the formation of a new socio-cultural environment, which is based on a wide access to a variety of sources of information. Mass distribution of the Internet has a direct impact on socialization processes of the representatives of βZ-generationβ who spend enormous amount of time in a cyberspace, quite often losing at the same time an ability of real personal development, interest in acquisition of skills for real interaction and effective communication. In this regard, the research of a phenomenon of a new, virtual identity of the personality, which is formed in the Internet environment, is brought into focus. The aim of the present publication is to consider the current level of knowledge in the field of virtual identity and systematization of scientific knowledge of this phenomenon. Methodology and research methods. Theoretical analysis, methods of synthesis and generalization were used. Results and scientific novelty. Various approaches to interpretation of virtual identity are considered; research tendencies are highlighted. The concepts βreal identityβ and βvirtual identityβ are viewed in relation to each other; the features and risks of virtual identity formation are revealed. The functions of virtual identity are specified. It is revealed that virtual identity reflects the subjectively significant image of the βIdeal-Iβ which is compiled from the completed material, character set and graphic images of the Internet environment, and therefore does not possess the uniqueness. Factors of designing by the person of virtual identity are described. Virtual identity can arise as a result of dissatisfaction with real identity, as a consequence of the identification crisis, in which the individual loses integrity. At the same time, it is shown that the cyberspace gives ample opportunities for self-expression and maximum personal fulfillment, realization of qualities, playing of roles and experience of emotions which turn out to be frustrated under any circumstances in real life. Problem areas of excessive immersion into virtual space are identified. An immature personality can lose life orientations as well as acquire the programmed decisions and ready cogitative patterns through excessive Internet use. The social activity in the Internet environment significantly reduces the moral level of communication on social networking sites and messengers. Aspiration always βto be onlineβ, fear to miss a new message or a post aggravate anxiety of the user, increase the feeling of fatigue and uncontrollable temper, scant attention and strongwilled self-regulation, aggravation of a hypodynamia.The authors conclude that is required to continue to study the specifics of socialization in the Internet environment since it generates new forms of age development, changes the tasks and ideas of children and teenagers about social relations, and transforms an ideal image of the subsequent age stages in their consciousness. Practical significance. The results of the work carried out can be applied in the activities of teachers, social educators, educators, psychologists and otherΒ specialists who deal with the questions of socialization of modern children and adolescents.Β ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

Quantum Electrodynamics at Extremely Small Distances
The asymptotics of the Gell-Mann - Low function in QED can be determined
exactly, \beta(g)= g at g\to\infty, where g=e^2 is the running fine structure
constant. It solves the problem of pure QED at small distances L and gives the
behavior g\sim L^{-2}.Comment: Latex, 6 pages, 1 figure include
Exclusion of Tiny Interstellar Dust Grains from the Heliosphere
The distribution of interstellar dust grains (ISDG) observed in the Solar
System depends on the nature of the interstellar medium-solar wind interaction.
The charge of the grains couples them to the interstellar magnetic field (ISMF)
resulting in some fraction of grains being excluded from the heliosphere while
grains on the larger end of the size distribution, with gyroradii comparable to
the size of the heliosphere, penetrate the termination shock. This results in a
skewing the size distribution detected in the Solar System.
We present new calculations of grain trajectories and the resultant grain
density distribution for small ISDGs propagating through the heliosphere. We
make use of detailed heliosphere model results, using three-dimensional (3-D)
magnetohydrodynamic/kinetic models designed to match data on the shape of the
termination shock and the relative deflection of interstellar neutral H and He
flowing into the heliosphere. We find that the necessary inclination of the
ISMF relative to the inflow direction results in an asymmetry in the
distribution of the larger grains (0.1 micron) that penetrate the heliopause.
Smaller grains (0.01 micron) are completely excluded from the Solar System at
the heliopause.Comment: 5 pages, 5 figures, accepted for publication in the Solar Wind 12

Rim curvature anomaly in thin conical sheets revisited
This paper revisits one of the puzzling behaviors in a developable cone
(d-cone), the shape obtained by pushing a thin sheet into a circular container
of radius by a distance [E. Cerda, S. Chaieb, F. Melo, and L.
Mahadevan, {\sl Nature} {\bf 401}, 46 (1999)]. The mean curvature was reported
to vanish at the rim where the d-cone is supported [T. Liang and T. A. Witten,
{\sl Phys. Rev. E} {\bf 73}, 046604 (2006)]. We investigate the ratio of the
two principal curvatures versus sheet thickness over a wider dynamic range
than was used previously, holding and fixed. Instead of tending
towards 1 as suggested by previous work, the ratio scales as .
Thus the mean curvature does not vanish for very thin sheets as previously
claimed. Moreover, we find that the normalized rim profile of radial curvature
in a d-cone is identical to that in a "c-cone" which is made by pushing a
regular cone into a circular container. In both c-cones and d-cones, the ratio
of the principal curvatures at the rim scales as ,
where is the pushing force and is the Young's modulus. Scaling
arguments and analytical solutions confirm the numerical results.Comment: 25 pages, 12 figures. Added references. Corrected typos. Results

Specifics of impurity effects in ferropnictide superconductors
Effects of impurities and disorder on quasiparticle spectrum in
superconducting iron pnictides are considered. Possibility for occurrence of
localized energy levels due to impurities within the superconducting gap and
the related modification of band structure and of superconducting order
parameter are discussed. The evolution of superconducting state with impurity
doping is traced.Comment: 9 pages, 8 figure
Origin of four-fold anisotropy in square lattices of circular ferromagnetic dots
We discuss the four-fold anisotropy of in-plane ferromagnetic resonance (FMR)
field , found in a square lattice of circular Permalloy dots when the
interdot distance gets comparable to the dot diameter . The minimum
, along the lattice axes,
differ by 50 Oe at = 1.1. This anisotropy, not expected in
uniformly magnetized dots, is explained by a non-uniform magnetization
\bm(\br) in a dot in response to dipolar forces in the patterned magnetic
structure. It is well described by an iterative solution of a continuous
variational procedure.Comment: 4 pages, 3 figures, revtex, details of analytic calculation and new

Search for sterile neutrinos at the DANSS experiment
DANSS is a highly segmented 1~m plastic scintillator detector. Its 2500
one meter long scintillator strips have a Gd-loaded reflective cover. The DANSS
detector is placed under an industrial 3.1~ reactor of the
Kalinin Nuclear Power Plant 350~km NW from Moscow. The distance to the core is
varied on-line from 10.7~m to 12.7~m. The reactor building provides about 50~m
water-equivalent shielding against the cosmic background. DANSS detects almost
5000 per day at the closest position with the cosmic
background less than 3. The inverse beta decay process is used to detect
. Sterile neutrinos are searched for assuming the model
(3 active and 1 sterile ). The exclusion area in the plane is obtained using a ratio of positron energy
spectra collected at different distances. Therefore results do not depend on
the shape and normalization of the reactor spectrum, as well
as on the detector efficiency. Results are based on 966 thousand antineutrino
events collected at 3 distances from the reactor core. The excluded area covers
a wide range of the sterile neutrino parameters up to
in the most sensitive region.Comment: 10 pages, 13 figures, version accepted for publicatio
Gibbs attractor: a chaotic nearly Hamiltonian system, driven by external harmonic force
A chaotic autonomous Hamiltonian systems, perturbed by small damping and
small external force, harmonically dependent on time, can acquire a strange
attractor with properties similar to that of the canonical distribution - the
Gibbs attractor. The evolution of the energy in such systems can be described
as the energy diffusion. For the nonlinear Pullen - Edmonds oscillator with two
degrees of freedom the properties of the Gibbs attractor and their dependence
on parameters of the perturbation are studied both analytically and
numerically.Comment: 8 pages RevTeX, 3 figure
Two problems related to prescribed curvature measures
Existence of convex body with prescribed generalized curvature measures is

techniques. In surprise, that methods has also brought us to promote
Ivochkina's estimates for prescribed curvature equation in \cite{I1, I}.Comment: 12 pages, Corrected typo
