Interpretative Translation Theory and Its Evaluation by Russian and Foreign Translators and Translation Studies Scholars
This article analyzes the current status of the interpretative translation theory, which, compared to other translation theories, does not study the result of translation, with its dependence on multiple factors, but instead focuses on the process of translation, which does not differ depending on the language and remains the same for all types of translation and text types. The authors draw attention to the evaluation of this theory by various translation schools: French school, where the theory is universally acknowledged and accepted, taking into account the fact that this school is represented by E.S.I.T. (High School of Interpretation and Translation, Paris, France) graduates; former French colonies, where the French language has lost its influence but remains demanded in science and education (for instance, Vietnam), Canadian (English-speaking) and Russian translation schools. This work outlines the ambiguous attitude to the interpretative translation theory by many leading Russian scholars; certain discrepancies in its understanding by Canadian translation studies specialists, who pay more attention to translation issues and partially depart from the main principles of the interpretative theory. Besides, it studies the works of researchers from other countries, who have written their articles in English. The article analyzes both theoretical approaches and attitude to the interpretative translation theory of practicing translators and interpreters and provides their evaluation of this theory as a regularly applied translation technology

Here we use locally sensitive X-ray absorption fine structure spectroscopy (XAFS) to get insight into the nature of phase transitions and the rearrangements of local electronic and crystal structure in archetypal metal hydride YH3 under pressure up to 180 GPa. The combination of the experimental methods allowed us to implement a multiscale length study of YH3: XAFS (short-range), Raman scattering (medium-range) and XRD (long-range). XANES data evidence a strong effect of hydrogen on the density of 4d yttrium states that increases with pressure and EXAFS data evidence a strong anharmonicity, manifested as yttrium atom vibrations in a double-well potential.--//--This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Demonstration of a parity-time symmetry breaking phase transition using superconducting and trapped-ion qutrits
Scalable quantum computers hold the promise to solve hard computational
problems, such as prime factorization, combinatorial optimization, simulation
of many-body physics, and quantum chemistry. While being key to understanding
many real-world phenomena, simulation of non-conservative quantum dynamics
presents a challenge for unitary quantum computation. In this work, we focus on
simulating non-unitary parity-time symmetric systems, which exhibit a
distinctive symmetry-breaking phase transition as well as other unique features
that have no counterpart in closed systems. We show that a qutrit, a
three-level quantum system, is capable of realizing this non-equilibrium phase
transition. By using two physical platforms - an array of trapped ions and a
superconducting transmon - and by controlling their three energy levels in a
digital manner, we experimentally simulate the parity-time symmetry-breaking
phase transition. Our results indicate the potential advantage of multi-level
(qudit) processors in simulating physical effects, where additional accessible
levels can play the role of a controlled environment.Comment: 14 pages, 9 figure
Three-dimensional Self-Ordering in an InGaAs/GaAs Multilayered Quantum Dot Structure Investigated by X-Ray Diffuse Scattering
A Novel Multi-Detection Technique for 3D Reciprocal Space Mapping in Grazing Incidence X-Ray Diffraction
A new scattering technique in grazing-incidence X-ray diffraction geometry is described which enables three-dimensional mapping of reciprocal space by a single rocking scan of the sample. This is achieved by using a two-dimensional detector. The new set-up is discussed in terms of angular resolution and dynamic range of scattered intensity. As an example the diffuse scattering from a strained multilayer of self-assembled (In,Ga)As quantum dots grown on GaAs substrate is presented
Superconductivity at 215 K in lanthanum hydride at high pressures
We synthesized lanthanum hydride (LaHx) by laser heating of lanthanum in hydrogen atmosphere at pressure P = 170 GPa. The sample shows a superconducting step at 209 K and 170 GPa and temperature dependence of resistance. By releasing the pressure to 150 GPa, the superconducting transition temperature Tc increases to 215 K - the record Tc. This finding supports a way of achieving Tc higher than the one in H3S (203 K) in hydrides with sodalite-like structures, first proposed for CaH6 (Tc=245 K) and later for yttrium and lanthanum hydrides where higher, room temperature superconductivity is expected
