Results of the Baikal experiment on observations of macroscopic nonlocal correlations in reverse time
Although the general theory macroscopic quantum entanglement of is still in
its infancy, consideration of the matter in the framework of action-at-a
distance electrodynamics predicts for the random dissipative processes
observability of the advanced nonlocal correlations. These correlations were
really revealed in our previous experiments with some large-scale
heliogeophysical processes as the source ones and the lab detectors as the
probe ones. Recently a new experiment has been performing on the base of Baikal
Deep Water Neutrino Observatory. The thick water layer is an excellent shield
against any local impacts on the detectors. The first annual series 2012/2013
has demonstrated that detector signals respond to the heliogeophysical
processes and causal connection of the signals directed downwards: from the
Earth surface to the Baikal floor. But this nonlocal connection proved to be in
reverse time. In addition advanced nonlocal correlation of the detector signal
with the regional source-process: the random component of hydrological activity
in the upper layer was revealed and the possibility of its forecast on nonlocal
correlations was demonstrated. But the strongest macroscopic nonlocal
correlations are observed at extremely low frequencies, that is at periods of
several months. Therefore the above results should be verified in a longer
experiment. We verify them by data of the second annual series 2013/2014 of the
Baikal experiment. All the results have been confirmed, although some
quantitative parameters of correlations and time reversal causal links turned
out different due to nonstationarity of the source-processes. A new result is
displaying of the advanced response of nonlocal correlation detector to the
earthquake. This opens up the prospect of the earthquake forecast on the new
physical principle, although further confirmation in the next events is
certainly needed.Comment: 9 pages, 9 figure
Uniform approximation of Poisson integrals of functions from the class H_omega by de la Vallee Poussin sums
We obtain asymptotic equalities for least upper bounds of deviations in the
uniform metric of de la Vall\'{e}e Poussin sums on the sets
C^{q}_{\beta}H_\omega of Poisson integrals of functions from the class H_\omega
generated by convex upwards moduli of continuity \omega(t) which satisfy the
condition \omega(t)/t\to\infty as t\to 0. As an implication, a solution of the
Kolmogorov-Nikol'skii problem for de la Vall\'{e}e Poussin sums on the sets of
Poisson integrals of functions belonging to Lipschitz classes H^\alpha,
0<\alpha <1, is obtaine
First measurements of spin correlations in the np -> d pi^0 reaction
The transverse spin correlations Axx and Ayy in the np-> d pi^0 reaction have
been measured for the first time in quasi-free kinematics at the COSY-ANKE
facility using a polarised deuteron beam incident on a polarised hydrogen cell
target. The results obtained for neutron energies close to 353 MeV and 600 MeV
are in good agreement with the partial wave analysis of data on the
isospin-related pp-> d pi^+ reaction, though the present results cover also the
small-angle region, which was largely absent from these data
Measurement of the analyzing powers in pd elastic and pn quasi-elastic scattering at small angles
The analyzing powers in proton-deuteron elastic and proton-neutron
quasi-elastic scattering have been measured at small angles using a polarized
proton beam at the COSY storage ring incident on an unpolarized deuterium
target. The data were taken at 796MeV and five higher energies from 1600MeV to
2400MeV. The analyzing power in pd elastic scattering was studied by detecting
the low energy recoil deuteron in telescopes placed symmetrically in the COSY
plane to the left and right of the beam whereas for pn quasi-elastic scattering
a low energy proton was registered in one of the telescopes in coincidence with
a fast scattered proton measured in the ANKE magnetic spectrometer. Though the
experiment explores new domains, the results are consistent with the limited
published information.Comment: 10 pages with 8 figure
Coherent pion production in proton-deuteron collisions
Values of the proton analysing power in the
reactions at 350-360~MeV
per nucleon were obtained by using a polarised proton beam incident on a
deuterium cluster-jet target and with a polarised deuteron beam incident on a
target cell filled with polarised hydrogen. These results have a much larger
angular coverage than existing data. First measurements are also presented of
the deuteron vector analysing power and the deuteron-proton spin correlations.
Data were also obtained on the deuteron-proton spin correlation and proton
analysing power at small angles at 600~MeV per nucleon, though the angular
coverage at this energy was much more restricted even when using a deuteron
beam. By combining the extrapolated values of the spin correlations to the
forward or backward directions with published measurements of the deuteron
tensor analysing powers, the relative phases between the two non-vanishing
amplitudes were evaluated.Comment: 5 pages, 5 figure
Analysing powers and spin correlations in deuteron-proton charge exchange at 726 MeV
The charge exchange of vector polarised deuterons on a polarised hydrogen
target has been studied in a high statistics experiment at the COSY-ANKE
facility at a deuteron beam energy of Td = 726 MeV. By selecting two fast
protons at low relative energy E_{pp}, the measured analysing powers and spin
correlations are sensitive to interference terms between specific
neutron-proton charge-exchange amplitudes at a neutron kinetic energy of Tn ~
1/2 Td =363 MeV. An impulse approximation calculation, which takes into account
corrections due to the angular distribution in the diproton, describes
reasonably the dependence of the data on both E_{pp} and the momentum transfer.
This lends broad support to the current neutron-proton partial-wave solution
that was used in the estimation
CONTENTS DIPHTHERIA ANTITOXIC AND ANTIBACTERIAL ANTIBODIES IN THE SERUM OF HEALTHY ADULTS
In the article using the binomial distribution analysis of the intensity of рориlation antitoxic (AT) and antibacterial (AB) of immunity to diphtheria in terms of specific diphtheria antibodies in the sera of healthy adults aged 20 to 51 years and. older, living in Russia and. Italy. The latter, in contrast to Russia, during the epidemic was only a few cases of diphtheria. For the population of people from Italy the optimal parameters of tension antibody immunity (bimodal distribution of the concentrations of AT antibodies) are determined, whereas for the adult population of Russia experienced an abnormally high, overvoltages antibody immunity (lack of bimodal distribution). The level of concentration of antibody isotypes AB M, G, A in both countries match the total synthesis of immunoglobulin isotypes in the ontogeny of these: thus, in the sera of adults aged 20 to 40 years AB antibody IgG prevail. Low concentrations of antitoxin in the blood of most adults living in Italy, recharged high AB IgG in these same serum, and. optimal concentrations of AB IgM and. IgA. This indicates the possibility lifting the mass revaccination of adults, and. creating an individual approach to their boosters. Optimal bimodal distribution of AB antibodies in the population of healthy adults, both in Russia and. in Italy, is an additional protection to the diphtheria antitoxic resistance
