Депрессивные расстройства при патологии молочной железы
We examined of 116 patients with chronic cystic mastitis, 38 patients with malignant mammary neoplasm, and 29 patients without any pathologic of mammary. We estimated complaints of patients their life and medical history, and depression which was estimated by scales of Beak. In our research depression disorder dominates in group patients with chronic cystic mastitis - 49%, in group with breast cancer it consists — 34%, and in control group — 35%.Проведено обследование 116 пациенток с различными по степени выраженности проявлениями фиброзно-кистозной мастопатии, 38 человек со злокачественными новообразованиями молочной железы и 29 человек, не страдающих патологией молочной железы. На основании жалоб, анамнеза и шкалы для определения депрессивных расстройств выявлены различные по степени выраженности депрессивные расстройства. Депрессивные расстройства преобладали в группе пациенток с мастопатией (49%), при раке установлены в 34% случаев и в контрольной группе в 35%
Novel Lyssaviruses Isolated from Bats in Russia
Two new rabies-related viruses were discovered in Russia during 2002. Viruses were isolated from bats in Eastern Siberia near Baikal Lake and in the western Caucasus Mountains. After preliminary antigenic and genetic characterization, we found that both viruses should be considered as new putative lyssavirus genotypes
Prompt, early, and afterglow optical observations of five gamma-ray bursts (GRBs 100901A, 100902A, 100905A, 100906A, and 101020A)
We present results of the prompt, early, and afterglow optical observations
of five gamma-ray bursts, GRBs 100901A, 100902A, 100905A, 100906A, and 101020A,
made with the Mobile Astronomical System of TElescope-Robots in Russia
(MASTER-II net), the 1.5-m telescope of Sierra-Nevada Observatory, and the
2.56-m Nordic Optical Telescope. For two sources, GRB 100901A and GRB 100906A,
we detected optical counterparts and obtained light curves starting before
cessation of gamma-ray emission, at 113 s and 48 s after the trigger,
respectively. Observations of GRB 100906A were conducted with two polarizing
filters. Observations of the other three bursts gave the upper limits on the
optical flux; their properties are briefly discussed. More detailed analysis of
GRB 100901A and GRB 100906A supplemented by Swift data provides the following
results and indicates different origins of the prompt optical radiation in the
two bursts. The light curves patterns and spectral distributions suggest a
common production site of the prompt optical and high-energy emission in GRB
100901A. Results of spectral fits for GRB 100901A in the range from the optical
to X-rays favor power-law energy distributions with similar values of the
optical extinction in the host galaxy. GRB 100906A produced a smoothly peaking
optical light curve suggesting that the prompt optical radiation in this GRB
originated in a front shock. This is supported by a spectral analysis. We have
found that the Amati and Ghirlanda relations are satisfied for GRB 100906A. An
upper limit on the value of the optical extinction on the host of GRB 100906A
is obtained.Comment: 18 pages, 14 figures, 14 tables, 5 machine readable tables; accepted

The HiSCORE Project
A central question of Astroparticle Physics, the origin of cosmic rays, still remains unsolved. HiSCORE (Hundred*i Square-km Cosmic ORigin Explorer) is a concept for a large-area wide-angle non-imaging air shower detector, addressing this question by searching for cosmic ray pevatrons in the energy range from 10TeV to few PeV and cosmic rays in the energy range above 100TeV. In the framework of the Tunka-HiSCORE project, first prototypes have been deployed on the site of the Tunka-133 experiment, where we plan to install an engineering array covering an area of the order of 1km2. On the same site, also imaging and particle detectors are planned, potentially allowing a future hybrid detector system. Here we present the HiSCORE detector principle, its potential for cosmic ray origin search and the status of ongoing activities in the framework of the Tunka-HiSCORE experiment
Simultaneous measurements of water optical properties by AC9 transmissometer and ASP-15 Inherent Optical Properties meter in Lake Baikal
Measurements of optical properties in media enclosing Cherenkov neutrino
telescopes are important not only at the moment of the selection of an adequate
site, but also for the continuous characterization of the medium as a function
of time. Over the two last decades, the Baikal collaboration has been measuring
the optical properties of the deep water in Lake Baikal (Siberia) where, since
April 1998, the neutrino telescope NT-200 is in operation. Measurements have
been made with custom devices. The NEMO Collaboration, aiming at the
construction of a km3 Cherenkov neutrino detector in the Mediterranean Sea, has
developed an experimental setup for the measurement of oceanographic and
optical properties of deep sea water. This setup is based on a commercial
transmissometer. During a joint campaign of the two collaborations in March and
April 2001, light absorption, scattering and attenuation in water have been
measured. The results are compatible with previous ones reported by the Baikal
Collaboration and show convincing agreement between the two experimental
techniques.Comment: 16 pages, submitted to NIM-
Method of Separation Between Light and Heavy Groups of Primary CR Nuclei by LDF of Cherenkov Light in the Range 300–3000 TeV
The problem of chemical composition below the knee in the cosmic-ray energy spectrum has not yet been solved due to low statistics collected from direct experiments. In the HiSCORE experiment the lateral distribution functions (LDF) of Cherenkov light of EASs with energy greater than hundreds of TeV can be measured in detail for millions of individual events. A full steepness of LDF is sensitive to the depth of shower maximum and as a result to primary particle type. In this paper, we developed a parametric method of separation between heavy and light groups of nuclei using the ’knee-like’ approximation of LDF and taking into account measurement uncertainty
