We present the results of studying the structure and dynamics of the HF-heated volume above the Sura facility obtained in 2010 by measurements of ionospheric airglow in the red (λ = 630 nm) and green (λ = 557.7 nm) lines ...
SENSING of the structure of the radio wave refractivity in the troposphere by a network of satellite navigation system receivers in the city of Kazan

Khutorova O.; Teptin G.; Vassilyev A.; Khutorov V.; Shlychkov A. (2011)

We present the results of an experimental study of the structure of the radio-wave refractivity and its dynamics by a network of seven ground-based GPS and GLONASS receivers in Kazan, Russia. It is shown that the remote ...
Study of mesoscale irregularities of the refraction coefficient of radiowaves in the troposphere by the methods of numerical simulation

Teptin G.; Khutorova O.; Zinin D.; Khutorov V. (2010)

We propose a model of the mesoscale irregular structure of the refraction coefficient of radiowaves and its dynamics in the real atmosphere at altitudes of up to 20 km. This model was verified according to multiyear ...
Diagnostics of artificial ionospheric irregularities using short sounding radio paths

Bolotin I.; Frolov V.; Akchurin A.; Zykov E.; Yusupov K. (2012)

In this work, we consider the possibilities of diagnostics of artificial ionospheric irregularities with the transverse size l⊥ ≈ 50-200 m, which are excited in the Earth's ionosphere by highpower short-wave radio-frequency ...
Some characteristics of low-amplitude cardiac signals

Teptin G.; Latfullin I.; Mamedova L.; Kim Z. (2011)

We present the results of an experimental study of the low-amplitude cardiac signals without temporal and spatial averaging. The characteristics of the fluctuation and quasi-periodic components of the low-amplitude signals ...
A high-resolution diatom-inferred palaeoconductivity and lake level record of the Aral Sea for the last 1600 yr

Austin P.; Mackay A.; Palagushkina O.; Leng M. (2007)

Formerly the world's fourth largest lake by area, the Aral Sea is presently undergoing extreme desiccation due to large-scale irrigation strategies implemented in the Soviet era. As part of the INTAS-funded CLIMAN project ...
Control of wind strength and frequency in the Aral Sea basin during the late Holocene

Sorrel P.; Oberhänsli H.; Boroffka N.; Nourgaliev D.; Dulski P.; Röhl U. (2007)

Changing content of detrital input in laminated sediments traced by XRF scanning and microfacies analyses reflect prominent variations in sedimentation processes in the Aral Sea. A high-resolution record of titanium from ...
Three-phase eccentric annulus subjected to a potential field induced by arbitrary singularities

Obnosov Y. (2011)

An infinite planar, three-component heterogeneous medium with a pair of circles as interfaces between homogeneous zones forming an eccentric annulus is considered for refraction of a potential field on the two interfaces. ...
A model four-phase square checkerboard structure

Craster R.; Obnosov Y. (2006)

Two-dimensional multi-phase doubly-periodic composites are considered with the emphasis upon a structure that is a four-phased square checkerboard. The structure of the checkerboard is such that it reduces to an oft-studied ...
Structure of associative subalgebras of Jordan operator algebras

Hamhalter J.; Turilova E. (2013)

We show that any order isomorphism between ordered structures of associative unital JB-subalgebras (Jordan-Banach) of JBW algebras (dual Jodan-Banach) is implemented naturally by a Jordan isomorphism. Consequently, JBW ...
Justification of a Galerkin method for a regularized Cauchy singular integro-differential equation

Fedotov A. (2009)

For one class of the singular integro-differential equations with Cauchy kernel on an interval, a Galerkin method is justified. The convergence is proved and the error estimation is given. © 2009 Brown University.
Electrochemical nucleic acid-based biosensors: Concepts, terms, and methodology (IUPAC Technical Report)

Labuda J.; Oliveira Brett A.; Evtugyn G.; Fojta M.; Mascini M.; Ozsoz M.; Palchetti I.; Paleček E.; Wang J. (2010)

An electrochemical nucleic acid (NA)-based biosensor is a biosensor that integrates a nucleic acid as the biological recognition element and an electrode as the electrochemical signal transducer. The present report provides ...
Strong limit theorems in the multi-color generalized allocation scheme

Chuprunov A.; Fazekas I. (2014)

The generalized allocation scheme is studied. Its extension for coloured balls is defined. Some analogues of the Law of the Iterated Logarithm and the Strong Law of Large Numbers are obtained for the number of boxes ...
An inequality for moments and its applications to the generalized allocation scheme

Chuprunov A.; Fazekas I. (2010)

An inequality for conditional moments of centered random variables is proved. This inequality is applied to the generalized allocation scheme. For the generalized allocation scheme an exponential inequality is obtained. ...
Search for signatures of reflected light from the exoplanet HD 189733b by the method of residual dynamical spectra

Growth, size-age structure of catches and reproduction of the Volga zander Sander volgensis (Percidae) in the upper part of the Volga stretch of the Kuibyshev Reservoir

Kuznetsov V. (2010)

Conditions of reproduction, size-age structure of catches, and the growth of the Volga zander Sunder volgensis in the upper part of the Volga stretch of the Kuibyshev Reservoir from 2002 to 2007, as well as its fishery in ...
A continuous analogue of the invariance principle and its almost sure version

Permiakova E. (2007)

We deal with random processes obtained from a homogeneous random process with independent increments by replacement of the time scale and by multiplication by a norming constant. We prove the convergence in distribution ...
Detection of regular low-amplitude photometric variability of the magnetic dwarf WD0009+501. On the possibility of photometric investigation of exoplanets on the basis of 1-meter class telescopes of the special and crimean astrophysical observatories
