LASERCOOLED RaF AS A LABORATORY FOR TESTING FUNDAMENTAL SYMMETRIES
No full textAuthor Institution: Clemens-Schopf Institute, Technical University of Darmstadt, 64287 Darmstadt, GermanyModern spectroscopical methods allow to reach an accuracy in measurements of molecular spectra that is sufficient for testing symmetry violation in fundamental weak interactions. As was demonstrated in recent experimental search for a permanent electric dipole moment of the electron in YbF [1] and PbO [2], diatomic molecules with an open electronic shell present extremely powerful instrument to study violations of space parity (-odd) and space parity and time reversal (-odd) symmetries. In this talk we discuss the enhancement of -odd and -odd effects in diatomic molecules and consider some prospective candidates for carrying out successful measurements. Radium monofluoride is shown to be a very prospective molecular candidate for observing possible symmetry violations due to its predicted suitability to direct laser cooling [3], large enhancement factors (both electronic and nuclear) [4] and efficient (for the given class of molecules) production route. \\~ REFERENCES: \begin{enumerate} \item J.

Impact of lattice vibrations on equation of state of the hardest boron phase
No full textAn accurate equation of state (EOS) is determined for the high-pressure orthorhombic phase of boron, B(28), experimentally as well as from ab initio calculations. The unique feature of our experiment is that it is carried out on the single crystal of B(28). In theory, we take into consideration the lattice vibrations, often neglected in first-principles simulations. We show that the phonon contribution has a profound effect on the EOS of B(28), giving rise to anomalously low values of the pressure derivative of the bulk modulus and greatly improving the agreement between theory and experiment.Original Publication:Eyvas Isaev, Sergey Simak, Arkady Mikhaylushkin, Yu.

Vojna i mir v tvorčestve i v myšlenii Velimira Chlebnikova [Guerra e pace nell'opera e nel pensiero di Velimir Chlebnikov]
No full textNell'articolo si illustrano le posizioni del poeta futurista russo nei confronti della Prima Guerra Mondiale, il suo passaggio da posizioni scioviniste e panslaviste negli anni precedenti il conflitto a un rifiuto della guerra e una ricerca utopica di "leggi del tempo" per superare e sconfiggere futuri conflitti
AUTHOR STRATEGIES IN RYURIK IVNEV’S “SUN IN THE COFFIN”. BOOK OF POEMS
No full textThe author’s problem in Ryurik Ivnev’s ‘The Sun in the Coffin’ (1921) is studied from the author’s perspectives. It is concluded that at least three Ryurik Ivnev’s strategies as an author can be distinguished: the first, the least obvious, coming from his youthful excitement about Nadson’s neo-romantic poetry, Baudelaire’s and Blok’s symbolism and appearing in a very weakened form, can be called a decadent one. The second strategy is determined by the poet’s recent belonging to egofuturism. The third one was formed under the influence of imaginism aesthetics, to which the poet was attracted when writing the book. Ryurik Ivnev’s strategies, spontaneously but sometimes consciously, were aimed at forming the literary image of the author, identified with the persona. The themes and motives of the book are concentrated around the hypertrophic and screened in the text «I» which becomes the center of Ryurik Ivnev’s poetic worldview. All the strategies are intricately intertwined and give rise to the quality of the style that distinguishes sharply ‘The Sun in the Coffin’ against the background of the Russian poetry of the 1920s and which can be referred to as surrealism
Theoretical study of linear monoatomic nanowires, dimer and bulk of Cu, Ag, Au, Ni, Pd and Pt
No full textThe binding and electronic properties of monoatomic nanowires, dimers and bulk structures of Cu, Ag, Au and Ni, Pd, Pt have been studied by the projector augmented-wave method (PAW) within the density functional theory (DFT) using the local density approximation (LDA) as well as generalized gradient approximation (GGA) in both Perdew–Wang (PW91) and Perdew–Burke–Ernzerhof (PBE) parameterizations. Our results show that the formation of atomic chains is not equally plausible for all the studied elements. In agreement with experimental observations Pt and Au stand out as most likely elements to form monoatomic wires. Changes in the electronic structure and magnetic properties of metal chains at stretching are analyzed.Original publication: E.Yu. Zarechnaya, N.V. Skorodumova, S.I. Simak, B. Johansson and E.I.

«Ja v cistom nerazumii pisal svoj pereverten’». Palindromy Chlebnikova: formal’nye i perevodceskie problemy ["Ho scritto il mio palindromo in uno stato di completa follia". I palindromi di Chlebnikov: problemi formali e di traduzione]
No full textNel contributo si analizza il ruolo della forma del palindromo nella poetica di V. Chlebnikov e in generale del futurismo russo, il suo nesso con una concezione rivoluzionaria della lingua, ma anche sullo sfondo della rivoluzione d'Ottobre. Si fa anche una rassegna della ripresa di questa forma nella poesia russa della fine degli anni Ottanta e della sua fortuna in Russia e anche all'estero. Si imposta poi la discussione su in che misura si possa parlare di traduzione del palindromo e se ciò sia possibile e in che modo
The State and Prospects of Postclassical Studies of Law
No full textIntroduction. The author of the article describes the history of the formation and development of postclassical studies of law. They originated in our country through the efforts of A. V. Polyakov in the early 2000s and today represent an important direction or approach in modern legal science. The authors who should be counted among the supporters of postclassical studies of law include N. V. Razuvaev, E.V. Timoshina, I. B. Lomakina, V.V.Arkhipov, E.N. Tonkov, D. E. Tonkov, L.A. Kharitonov, A. E. Chernokov, I. I. Osvetimskaya, E. G. Samokhina, Yu. A. Vedeneev, V. I. Pavlov, N. F. Kovkel, E. M. Krupenya, S. I. Maksimov, M. A. Belyaev, N. V. Malinovskaya, V. V. Denisenko, S. V. Tikhonov, A. V. Skorobogatov, A. V. Krasnov. The author believes that the works of V. V. Lazarev, I. A. Isaev, I. F. Machin, Y. Y. Vetyutnev, I. F. Nevvazhay, S. N. Kasatkin and some other scientists are close to postclassical studies of law. Among foreign scientists, we should mention E. Pattaro, B. Leiter, B. Brozhek, B. Melkevik, C. Varga, E. Fittipaldi, and others.Methodology and materials. Post-classical methodology is a method of studying “supercomplex systems”. What are postclassical studies of law in terms of their institutional status? The author argues that one cannot talk about a scientific school or a paradigm, but one can talk about a research program, an approach or direction.Results and discussion. The article discusses the substantive characteristics of postclassical studies of law. Among them, we are talking about the multidimensional nature of law, humanitarianism, and practical orientation.Conclusions. The differences between postclassical studies of law and postmodernism are shown. A demarcation line is drawn between classical, nonclassical and postclassical studies of law
