Gravitation and Cosmology | Year: 2017

It is known that to obtain cosmological solutions consistent with the Hubble law and accelerated expansion, it is necessary to represent space-time in the form of de Sitter space of the first kind, which ismost simply described by a Robertson-Walkermetric having the scale factor with exponential time dependence. In standard general relativity, this solution is obtained by introduction of the cosmological constant Λ associated with dark energy, whose nature is still not clear. It would be of some interest to consider theories allowing one to obtain cosmological-type solutions without using an effective Λ term. This role was at their time claimed by various supergravity theories which are low-energy approximations of superstring theories. However, it was found that in these theories there are so-called no-go theorems which do not allow solutions in the form of de Sitter space of the first kind. It turned out that this problem can be solved in at least two ways. The first way is to admit the possibility of extra time dimensions, as was demonstrated for the ten-dimensional supergravity by Arefyeva et al. Another way is to consider corrections of higher order in the curvature tensor, which is a subject of this paper. As is known, non-chiral ten-dimensional N = 2 supergravity is a low-energy approximation of type IIA superstring theory. In the present paper, we consider the effective action for type IIA superstring theory, taking into account fourthorder curvature corrections. It is shown that in this case, indeed, one can obtain a cosmological solution in the form of de Sitter space, describing an exponential expansion of space without an effective Λ term. © 2017, Pleiades Publishing, Ltd.

A many particle quantum-kinetic formalism is suggested to derive the Maxwell-Bloch-Type equations which describe the interaction of quantum emitters with light in a frozen dielectric. It is shown that the quantum-kinetic formalism can meet the concept of local variations of dielectric properties and their influence on the emitter. The definitions of the local response and the effective refractive index in macroscopically homogeneous media are discussed. © The Authors, published by EDP Sciences.

The present paper is a survey of a part of the theory devoted to certain problems concerning the algebraic independence of the values of analytic functions, to quantitative results on estimates for the measure of transcendence or the measure of algebraic independence of numbers, to functional analogs of these results on the algebraic independence of solutions of algebraic differential equations, and estimates for the multiplicities of zeros for polynomials in these solutions, which play an important role in the proof of numerical results. This choice is related to the fact that, in December 2016, the head of the Department of Number Theory of Moscow State University, Corresponding Member of the RAS Yu.V. Nesterenko, who did a lot to develop these directions of the theory Transcendental numbers and whose works are marked by many awards, became seventy. He is a laureate of the Markov RAS Prize, 2006, of the Ostrovsky international prize, 1997, of the Hardy–Ramanujan Society Prize, 1997, and the Alexander von Humboldt Prize, 2003. Since the article is dedicated to the 70th anniversary of the birth of Yurii Valentinovich, we preface the scientific part with a brief biography. © 2017, Pleiades Publishing, Ltd.

Following the recommendations of the Science Education Now: A renewed Pedagogy for the Future of Europe report, the Pathway Supporting Action is bringing together experts in the field of science education research and teachers communities, scientists and researchers involved in pioneering scientific research, policy makers and curriculum developers to promote the effective widespread use of inquiry and problem based science teaching techniques in primary and secondary schools in Europe and beyond. The proposed approach is based on three main axes that could facilitate the uptake of IBSE (Inquiry-Based Science Education): It a) proposes a standard-based approach to teaching science by inquiry that outlines instructional models that will help teachers to organise effectively their instruction, b) deploys a series of methods to motivate teachers to adopt inquiry based techniques and activities in their classrooms and c) offers access to a unique collection of open educational resources and teaching practices (linked with the science curricula) that have proven their efficiency and efficacy in promoting inquiry based education and that are expanding the limitations of classroom instruction. Such an approach enables all stakeholders (teachers, teachers trainers, curriculum developers, policy-makers) to examine their own practices in the light of the best performing approaches that set the standards on what can be achieved and provides them with a unique tool to bring about improvements in their everyday practice.

A single complex molecule with conformational changes (conformations 0 and 2) is considered. When such a molecule is irradiated by cw-laser light it can randomly change the intensity or polarization of its fluorescence due to jumps from one conformation to another. In fact, the molecule manifests itself either like the 0-type or the 2-type emitter. An expression for the matrix s αβ(t) called the start-stop correlator (waiting time distribution) in which α=0,2 and β=0,2 is derived. An expression for the matrix pαβ(t) called the full correlator is derived as well. It determines the density of the probability of finding an event of α type and an event of β type separated by time interval t. A relation between matrices sαβ(t) and p αβ(t) is found. A mathematical expression for the distribution wN(T) of events measured in time interval T is derived. It is expressed solely via the matrix sαβ(t). Numerical calculations of the event distribution function for various rates of intra- and interconformational jumps are carried out with the help of the formula for wN(T) and by the Monte Carlo method. Both methods of the calculation yield identical distributions. Fluctuating fluorescence intensity I(t) for a bin time of 5 ms is calculated for slow and fast interconformational jumps. A relation is found between the autocorrelation function g(2)(t) of fluorescence measurable in experiments and the matrix p αβ(t) calculated theoretically. © 2011 American Physical Society.

Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of the turbulence, power develops on large scales, which is not present in non-helical small-scale turbulent dynamos. At small length scales, differences occur in connection with the dissipation cutoff scales associated with the respective value of the magnetic Prandtl number. These differences are found to be independent of whether or not there is large-scale dynamo action. However, large-scale dynamos in homogeneous systems are shown to suffer from resistive slow-down even at intermediate length scales. The results from simulations are connected to mean field theory and its applications. Recent work on magnetic helicity fluxes to alleviate large-scale dynamo quenching, shear dynamos, nonlocal effects and magnetic structures from strong density stratification are highlighted. Several insights which arise from analytic considerations of small-scale dynamos are discussed. © 2012 Springer Science+Business Media B.V.

Published data on the preparation of phosphorus-containing cyclodextrins are summarized. It is demonstrated that some significant features of their synthesis and chemical behaviour are caused by specific supramolecular interactions involving the inner chiral cavity of cyclodextrins capable of incorporating various guests, which often leads to alteration of customary routes of chemical transformations. The possibilities of practical applications of phosphorus-containing cyclodextrins are briefly analyzed. The bibliography includes 89 references. © 2013 Russian Academy of Sciences and Turpion Ltd.


Sixty years ago, in 1952, Prof. E V Shpol'skii and his colleagues were the first to see quasilinear spectra from complex organic compounds in specially selected solvents at low temperatures. Twenty years later, in 1972, a team headed by Prof. RI Personov discovered laser fluorescence line narrowing in the solid solutions of organic dyes. These two discoveries served as the basis for the field of laser selective spectroscopy of impurity centers in solids. The work in this field culminated in the techniques of spectroscopy and luminescence imaging (microscopy) of single molecules in condensed matter. Today, optical spectroscopy of impurity centers in solid solutions has become one of the most popular tools for solving a wide variety of interdisciplinary problems in physics, physical chemistry, optics and spectroscopy, biophysics, quantum optics, and nano-technology. In this article, the development of this field is briefly reviewed, potentials of the developed methods are discussed, and some research results are highlighted. © 2013 Uspekhi Fizicheskikh Nauk, Russian Academy of Sciences.

Fluorescence of M noninteracting molecules, each of which exhibits blinking fluorescence with on- and off-intervals, is considered. Theoretical expressions suitable for statistical analysis of fluorescence of M molecules are derived. The derivation of (i) the distribution functions Pon,off(t) for on- and off-interval duration, (ii) the distribution function wN(t) for the number N of photons emitted at a time interval t, and (iii) the fluorescence autocorrelation function g(2)(t) is carried out with the help of the formulas previously derived for single molecule blinking fluorescence. The statistical treatment of intensity fluctuations in fluorescence of several molecules is carried out to find the three types of the above-mentioned functions. The coincidence of the functions "measured" in blinking fluorescence and those calculated with the help of the theoretical formulas derived proves the validity of the latter. © 2010 American Chemical Society.
