Eden growth model for aggregation of charged particles

The stochastic Eden model of charged particles aggregation in two-dimensional systems is presented. This model is governed by two parameters: screening length of electrostatic interaction, $\lambda$, and short range attraction energy, $E$. Different patterns of finite and infinite aggregates are observed. They are of following types of morphologies: linear or linear with bending, warm-like, DBM (dense-branching morphology), DBM with nucleus, and compact Eden-like. The transition between the different modes of growth is studied and phase diagram of the growth structures is obtained in $\lambda, E$ co-ordinates. The detailed aggregate structure analysis, including analysis of their fractal properties, is presented. The scheme of the internal inhomogeneous structure of aggregates is proposed.Comment: Revtex, 9 pages with 12 postscript figure

Deterministic growth model of Laplacian charged particle aggregates

The results of the computer simulation of the aggregates growth of the similarly charged particles in the framework of deterministic Laplacian growth model on a square lattice are presented. Cluster growth is controlled by three parameters ${p, E,\lambda}$, where $p$ - Laplacian growth parameter, $E$ - energy of a particle sticking to a cluster, $\lambda$ - the screening length of electrostatic interactions. The phase diagram of cluster growth is built in the co-ordinates ${E,\lambda}$. The zones of different cluster morphology are selected: I-the zone of finite X-like structures,II-the zone of infinite ramified structures, controlled by electrostatic interactions, III-the zone of infinite structures with electrostatic interactions effectively switched off. Simple electrostatic estimations of the locations of the zone boundaries are presented. It is shown that in general case within the zone II the continuous change of $D_f$, controlled by parameters ${p, E,\lambda}$, takes place. In the degeneration limit when the given model transforms into deterministic version of the Eden model (at $p=0$), the crossover from linear $(D_f=1)$ to compact $(D_f=2)$ structures is observed when passing through the boundary between the zones I and II.Comment: REVTEX, 3 pages with 4 postscript figure

ONTOLOGICAL AND SOCIO-CULTURAL FOUNDATIONS OF THE INTER-GENERATED DISCOURSE IN THE MODERN INFORMATION SOCIETY

Purpose of the study: The article is devoted to understanding the problems of intergenerational discourse and its transformation in ontological and sociocultural reality. The paper substantiates the need to maintain the mechanism of accumulation and reproduction of the experience of ancestors. It is shown that the violation of the transfer of knowledge and traditions leads to the distortion or disappearance of universal cultural codes. Methodology: In this article, cultural, demographic, and psychological approaches are used to study the ontological and sociocultural foundations of intergenerational discourse. It is necessary to show the influence of historical and socio-cultural transformations on the characteristics of interaction between generations, to determine the form of transfer and assimilation of experience within the family, to demonstrate the socially significant consequences of the demographic revolution in the modern information society. Main Findings: Having outlined only a few reasons for the intergenerational discourse in the field of translation of sociocultural experience, it can be noted that their combination forms the layer of human life in which historically determined values and ideals of human society are realized, methods of accumulation and transfer of experience that are unique for each historical era, new methods communications. Applications of this study: Research results can be applied in the course of social psychology (today, young people are literally imposed a radical cultural gap with previous generations), social philosophy, cultural studies (the form of transfer of experience within the family) and even demography (large-scale changes in human society, with the destruction of human social instincts). Novelty/Originality of this study: As the initial task of the study, it is supposed to identify historical and sociocultural changes in the field of translation and appropriation of experience, to conduct a cultural analysis that gives a clear idea of the evolution of the methods of interaction between generations. An interdisciplinary approach involves a wider coverage of existing concepts and shows that the patterns of development of human society cannot be reduced only to biological, economic or socio-cultural patterns

Shape of primary proton spectrum in multi-TeV region from data on vertical muon flux

It is shown, that primary proton spectrum, reconstructed from sea-level and underground data on muon spectrum with the use of QGSJET 01, QGSJET II, NEXUS 3.97 and SIBYLL 2.1 interaction models, demonstrates not only model-dependent intensity, but also model-dependent form. For correct reproduction of muon spectrum shape primary proton flux should have non-constant power index for all considered models, except SIBYLL 2.1, with break at energies around 10-15 TeV and value of exponent before break close to that obtained in ATIC-2 experiment. To validate presence of this break understanding of inclusive spectra behavior in fragmentation region in p-air collisions should be improved, but we show, that it is impossible to do on the basis of the existing experimental data on primary nuclei, atmospheric muon and hadron fluxes.Comment: Submitted to Phys. Rev.

Results of investigation of muon fluxes of superhigh energy cosmic rays with X-ray emulsion chambers

The overall data from the investigation of the cosmic ray muon flux in the range of zenith angles (0-90) deg within the energy range (3.5 to 5.0) TeV is presented. The exposure of large X-ray emulsion chambers underground was 1200 tons. year. The data were processe using the method which was applied in the experiment Pamir and differred from the earlier applied one. The obtained value of a slope power index of the differential energy spectrum of the global muon flux is =3.7 that corresponds to the slope of the pion generation differential spectrum, gamma sub PI = 2.75 + or - .04. The analysis of the muon zenith-angular distribution showed that the contribution of rapid generation muons in the total muon flux agree the best with the value .2% and less with .7% at a 90% reliability level

Dirac-Kaehler fermion with noncommutative differential forms on a lattice

Noncommutativity between a differential form and a function allows us to define differential operator satisfying Leibniz's rule on a lattice. We propose a new associative Clifford product defined on the lattice by introducing the noncommutative differential forms. We show that this Clifford product naturally leads to the Dirac-K\"ahler fermion on the lattice.Comment: 3 pages, Lattice2003(Theoretical Development

International Standards of Penitentiary Activity: Impact on the Development of the Penitentiary Activity of the CIS Countries

Overcrowding in prisons is a common problem that affects many countries. It is difficult to define this term because there is no single internationally accepted standard. This article presents a comparative study of international standards for the activities of doctors in penitentiary institutions as an integral part of international standards of penitentiary activity. The authors investigated the methods and the degree of their impact on the penitentiary legislation of the Russian Federation and other CIS countries. The conclusion is drawn about the positive role of such standards in improving the national penitentiary legislation in order to increase the level of medical care for prisoners

Note on Dirac--K\"ahler massless fields

We obtain the canonical and symmetrical Belinfante energy-momentum tensors of Dirac--K\"{a}hler's fields. It is shown that the traces of the energy-momentum tensors are not equal to zero. We find the canonical and Belinfante dilatation currents which are not conserved, but a new conserved dilatation current is obtained. It is pointed out that the conformal symmetry is broken. The canonical quantization is performed and the propagator of the massless fields in the first-order formalism is found.Comment: 16 pages, minor corrections in the text, published versio
