It is well known, that inclination of the Earth rotation axis to the ecliptic plain defines the maxima
and minima declination of the Sun on the days of solstices. According to the Milankovitch theory
variations of this parameter are one of the causes of the glacial periods. Some facts show, that motions
of the Moon from equator to ...

Предлагаемая читателю книга содержит наиболее важные и принципиальные разделы современной теории дисковой и квази-сферической аккреции на черные дыры и замагниченные нейтронные звезды. Последовательно излагается расчет структуры стандартной модели стационарной дисковой аккреции (альфа-модель). Показано, как из сравнения теории нестационарной дисковой аккреции с данными наблюдений нестационарных рентгеновских источников получаются оценки основных параметров модели. Излагается методика расчета релятивистских ...

Современному в меру образованному и уважающему себя человеку необходимо иметь представление о глобальном устройстве окружающего его мира. Изучая космическое пространство, мы имеем уникальную возможность заглянуть в далекое прошлое или будущее, не имея машины времени. В учебном пособии кратко рассматриваются теоретические основы общего курса астрономии: основные исторические факты развития науки, раскрытие методов и средств астрономических исследований, ...

Identification of fast-variable objects (transients) of astrophysical origin, especially short, such as optical counterparts of cosmic gamma-ray burst (GRB) associated with gravitational wave (GW) events, is a relevant research problem of the modern multi-messenger astronomy. The typical localization area of space gamma and X-ray telescopes or
ground-based GW detectors LIGO, Virgo and KAGRA (LVK) is up ...

This paper presents an algorithm for processing the transmission spectra of whisperinggallery optical microcavities for use as a nanoparticle detector. The algorithm is based on the broadening of the microcavity resonance curve during precipitation of nanoparticles on the microcavity surface. Experimental results on the detection of particles are compared with Langmuir adsorption theory. The contribution ...

To date, a number of lantibiotics have been shown to use lipid II — a highly conserved peptidoglycan precursor in the cytoplasmic membrane of bacteria — as their molecular target. The α-component (Lchα) of the two-component lantibiotic lichenicidin (Lchα), previously isolated from the Bacillus licheniformis VK21 strain, seems to contain two putative lipid II binding ...

We study regularization scheme dependence of beta-function for sigma models with two-dimensional target space. Working within four-loop approximation, we conjecture the scheme in which the beta-function retains only two tensor structures up to certain terms containing zeta_3. Using this scheme, we provide explicit solutions to RG flow equation corresponding to Yang-Baxter- and lambda-deformed SU(2)/U(1) sigma ...

FeCo and FeNi alloyed nanowires (NW) were obtained by the matrix synthesis method: the effect of the
growth voltage and the effect of using a reference electrode were studied. It is shown that the composition of
FeNi nanowires strongly depends on the growth potential (with its increase, the bcc structure is changing into
fcc), and it is also ...

In this work, we present for the first time the Lyman α intensities measured by Voyager 1/UVS in 2003–2014 (at 90–130 AU from the Sun). During this period Voyager 1 measured the Lyman α emission in the outer heliosphere at an almost fixed direction close to the upwind (i.e.“ toward the interstellar flow). The data show an unexpected behavior in 2003–2009: the ...

Zirconium trihydride and, for comparison, trideuteride with hexagonal close-packed (hcp) metal lattices
were synthesized at a hydrogen/deuterium pressure of 9 GPa and a temperature of 873 K using toroid-type
high-pressure chambers. After a rapid cooling (quenching) to 100 K and lowering the pressure to atmospheric,
the quenched sample was removed from the chamber and studied by hot extraction ...

We demonstrate that magnetoresistance of creeping charge-density waves in the quasi-one-dimensional
conductor o-TaS 3 changes its character from a negative parabolic at T 10 K, where it obeys the 1/T 2 law
to a weakly temperature-dependent negative nearly linear one at lower temperatures. The dominant contribution into the negative parabolic magnetoresistance comes from magnetic field induced ...

The parameters of unstable short-living isotopes are studied from
the mathematical point of view. The values of the chemical potential
and activity parameters that determine the neutron halo arising when
the neutron separates from the nucleus of an unstable isotope are
calculated. The analogy between nuclear physics and economics is
considered from the point of view of such parameters as ...

We analyze magnetic kinematic dynamo in a conducting fluid where the stationary shear flow is accompanied by relatively weak random velocity fluctuations. The diffusionless and diffusion regimes are described. The growth rates of the magnetic field moments are related to the statistical characteristics of the flow describing divergence of the Lagrangian trajectories. The magnetic field ...

Molecular dynamic models are created for properties of bivalent ions in organic solvents. It is shown that molecules of the considered solvents bound to ions via oxygen atoms. A theoretical model is developed that describes the ion coordination number. The coordination number in this model is determined by the ratio between the sizes of the ...

We present temperature dependences of the large and the small superconducting gaps measured directly by SnS-Andreev spectroscopy in various Fe-based superconductors and MgB2. The experimental L,S(T ) are wellfitted with a two-gap model based on Moskalenko and Suhl system of equations (supplemented with a BCS integral renormalization). From the fitting procedure, we estimate the key ...

Sequential state discrimination is a strategy for quantum state discrimination of a sender’s quantum
states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not
only binary phase-shifting-key (BPSK) signals but also general coherent states, with arbitrary prior
probabilities. Since ...

This paper describes the surface environment of the dense plasma arcs that damage rf accelerators, tokamaks, and other high gradient structures. We simulate the dense, nonideal plasma sheath near a metallic surface using molecular dynamics (MD) to evaluate sheaths in the non-Debye region for high density, low temperature plasmas. We use direct two-component MD simulations ...
