БИОЛОГИЧЕСКАЯ ДЕГРАДАЦИЯ HOMO SAPIENS: ПУТИ ПРОТИВОДЕЙСТВИЯ
Перед человечеством стоит проблема, значимость которой пока не осознаётся в достаточной мере ни общественностью, ни наукой - биологическая деградация вида Homo sapiens. Она проявляется ускоренным темпом старения, популяционным снижением «количества» здоровья (жизнеспособности), эпидемией хронических неинфекционных заболеваний (ХНИЗ), полиморбидностью, снижением уровня развития физических качеств и психофизиологических функций, репродуктивной функции, рождением ослабленного потомства, снижением IQ и многим другим. Всё это является следствием потери устойчивости неравновесной термодинамической системы (живого), т.е. дефицита внутриклеточной энергии, из-за противоречий между биологическими и социальными аспектами эволюции Человека
САНОЦЕНТРИЧНА СТРАТЕГІЯ ОХОРОНИ ЗДОРОВ'Я: ПРЯМИЙ ШЛЯХ ДО ЗДОРОВ'Я НАСЕЛЕННЯ
We discuss the fundamental position of the essence of life and health as a manifestation of the transformation of solar energy into other forms of energy (thermal, mechanical, electrical, etc.). It is alleged that the efficiency of intracellular energy production as an expression of mitochondrial function (the final stage of the transformation of solar energy) is a measure of the body's resistance to internal and external negative influences. There is a level of energy production above which neither endogenous risk factors, nor the disease are registered. It was given quantitative characteristic named «safe level of health». It is postulated (in addition to the «sickness industry» - the Ministry of Health institutions) the need to form the «health industry», based on the preservation and improvement of energy potential biosystems.Обсуждается фундаментальное положение о сущности жизни и здоровья как проявлении трансформации солнечной энергии в другие виды энергии (тепловую, механическую, электрическую и др.). Утверждается, что эффективность внутриклеточного энергообразования как проявление функции митохондрий (конечный этап трансформации солнечной энергии) является показателем устойчивости организма к внешним и внутренним негативным воздействиям. Существует уровень энергообразования, выше которого не регистрируются ни эндогенные факторы риска, ни сами заболевания. Ему дана количественная характеристика - «безопасный уровень здоровья». Постулируется необходимость в дополнение к «индустрии болезни» (учреждения Министерства здравоохранения) формирования «индустрии здоровья», в основе которой сохранение и повышение энергопотенциала биосистемы.Обговорюється фундаментальне положення про сутність життя та здоров'я як прояву трансформації сонячної енергії в інші види енергії (теплову, механічну, електричну тощо).

Існує рівень енергоутворення, вище якого не реєструються ні ендогенні фактори ризику, ні самі захворювання. Йому дана кількісна характеристика - «безпечний рівень здоров'я».

Peculiarities in produced particles emission in 208Pb + Ag(Br) interactions at 158 A GeV/c
The angular structures of particles produced in 208Pb induced collisions with
Ag(Br) nuclei in an emulsion detector at 158 A GeV/c have been investigated.
Nonstatistical ring-like substructures in azimuthal plane of the collision have
been found and their parameters have been determined. The indication on the
formation of the ring-like substructures from two symmetrical emission cones -
one in the forward and other in the backward direction in the center-of mass
system have been obtained. The ring-like substructures parameters have been
determined. The experimental results are in an agreement with I.M. Dremin idea,
that mechanism of the ring-like substructures formation in nuclear collisions
is similar to that of Cherenkov electromagnetic radiation.Comment: 10 pages, 7 figures, Report at the HADRON STRUCTURE'04 Conference,

Two-dimensional discrete wavelet analysis of multiparticle event topology in heavy ion collisions
The event-by-event analysis of multiparticle production in high energy hadron
and nuclei collisions can be performed using the discrete wavelet
transformation. The ring-like and jet-like structures in two-dimensional
angular histograms are well extracted by wavelet analysis. For the first time
the method is applied to the jet-like events with background simulated by event
generators, which are developed to describe nucleus-nucleus collisions at LHC
energies. The jet positions are located quite well by the discrete wavelet
transformation of angular particle distribution even in presence of strong
background.Comment: 6 pages, 6 figure
Wavelets: mathematics and applications
The notion of wavelets is defined. It is briefly described {\it what} are
wavelets, {\it how} to use them, {\it when} we do need them, {\it why} they are
preferred and {\it where} they have been applied. Then one proceeds to the
multiresolution analysis and fast wavelet transform as a standard procedure for
dealing with discrete wavelets. It is shown which specific features of signals
(functions) can be revealed by this analysis, but can not be found by other
methods (e.g., by the Fourier expansion). Finally, some examples of practical
application are given (in particular, to analysis of multiparticle production}.
Rigorous proofs of mathematical statements are omitted, and the reader is
referred to the corresponding literature.Comment: 16 pages, 5 figures, Latex, Phys. Atom. Nuc
Measurement of the cosmic ray hadron spectrum up to 30 TeV at mountain altitude: the primary proton spectrum
The flux of cosmic ray hadrons at the atmospheric depth of 820 g/cm^2 has
been measured by means of the EAS-TOP hadron calorimeter (Campo Imperatore,
National Gran Sasso Laboratories, 2005 m a.s.l.). The hadron spectrum is well
described by a single power law : S(E_h) = (2.25 +- 0.21 +- 0.34(sys))
10^(-7)(E_h/1000)^(-2.79 +- 0.05) m^(-2) s^(-1) sr^(-1) GeV^(-1) over the
energy range 30 GeV-30 TeV. The procedure and the accuracy of the measurement
are discussed. The primary proton spectrum is derived from the data by using
the CORSIKA/QGSJET code to compute the local hadron flux as a function of the
primary proton spectrum and to calculate and subtract the heavy nuclei
contribution (basing on direct measurements). Over a wide energy range E_0 =
0.5-50 TeV its best fit is given by a single power law : S(E_0) = (9.8 +- 1.1
+- 1.6(sys)) 10^(-5) (E_0/1000)^(-2.80 +- 0.06) m^(-2) s^(-1) sr^(-1) GeV^(-1).
The validity of the CORSIKA/QGSJET code for such application has been checked
using the EAS-TOP and KASCADE experimental data by reproducing the ratio of the
measured hadron fluxes at the two experimental depths (820 and 1030 g/cm^2
respectively) at better than 10% in the considered energy range.Comment: 16 pages, 9 figures, accepted for publication in Astroparticle

QCD in the nuclear medium and effects due to Cherenkov gluons
The equations of in-medium gluodynamics are proposed. Their classical lowest
order solution is explicitly shown for a color charge moving with constant
speed. For nuclear permittivity larger than 1 it describes emission of
Cherenkov gluons resembling results of classical electrodynamics. The values of
the real and imaginary parts of the nuclear permittivity are obtained from the
fits to experimental data on the double-humped structure around the away-side
jet obtained at RHIC. The dispersion of the nuclear permittivity is predicted
by comparing the RHIC, SPS and cosmic ray data. This is important for LHC
experiments. Cherenkov gluons may be responsible for the asymmetry of dilepton
mass spectra near rho-meson, observed in the SPS experiment with excess in the
low-mass wing of the resonance. This feature is predicted to be common for all
resonances. The "color rainbow" quantum effect might appear according to higher
order terms of in-medium QCD if the nuclear permittivity depends on color.Comment: 29 p., 4 figs; for "Phys. Atom. Nucl." volume dedicated to 80th

A study on the sharp knee and fine structures of cosmic ray spectra
The paper investigates the overall and detailed features of cosmic ray (CR)
spectra in the knee region using the scenario of nuclei-photon interactions
around the acceleration sources. Young supernova remnants can be the physical
realities of such kind of CR acceleration sites. The results show that the
model can well explain the following problems simultaneously with one set of
source parameters: the knee of CR spectra and the sharpness of the knee, the
detailed irregular structures of CR spectra, the so-called "component B" of
Galactic CRs, and the electron/positron excesses reported by recent
observations. The coherent explanation serves as evidence that at least a
portion of CRs might be accelerated at the sources similar to young supernova
remnants, and one set of source parameters indicates that this portion mainly
comes from standard sources or from a single source.Comment: 13 pages, 4 figures, accepted for publication in SCIENCE CHINA

On inconsistency of experimental data on primary nuclei spectra with sea level muon intensity measurements
For the first time a complete set of the most recent direct data on primary
cosmic ray spectra is used as input into calculations of muon flux at sea level
in wide energy range GeV. Computations have been performed
with the CORSIKA/QGSJET and CORSIKA/VENUS codes. The comparison of the obtained
muon intensity with the data of muon experiments shows, that measurements of
primary nuclei spectra conform to sea level muon data only up to several tens
of GeV and result in essential deficit of muons at higher energies. As it
follows from our examination, uncertainties in muon flux measurements and in
the description of nuclear cascades development are not suitable to explain
this contradiction, and the only remaining factor, leading to this situation,
is underestimation of primary light nuclei fluxes. We have considered
systematic effects, that may distort the results of the primary cosmic ray
measurements with the application of the emulsion chambers. We suggest, that
re-examination of these measurements is required with the employment of
different hadronic interaction models. Also, in our point of view, it is
necessary to perform estimates of possible influence of the fact, that sizable
fraction of events, identified as protons, actually are antiprotons. Study of
these cosmic ray component begins to attract much attention, but today nothing
definite is known for the energies GeV. In any case, to realize whether
the mentioned, or some other reasons are the sources of disagreement of the
data on primaries with the data on muons, the indicated effects should be
thoroughly analyzed
Thermal Dileptons at LHC
We predict dilepton invariant-mass spectra for central 5.5 ATeV Pb-Pb
collisions at LHC. Hadronic emission in the low-mass region is calculated using
in-medium spectral functions of light vector mesons within hadronic many-body
theory. In the intermediate-mass region thermal radiation from the Quark-Gluon
Plasma, evaluated perturbatively with hard-thermal loop corrections, takes
over. An important source over the entire mass range are decays of correlated
open-charm hadrons, rendering the nuclear modification of charm and bottom
spectra a critical ingredient.Comment: 2 pages, 2 figures, contributed to Workshop on Heavy Ion Collisions
