Русские солдаты Квантунской армии. – М. : Вече, 2014. – 320 с.The article reviews the book by E. V. Yakovkin Russian Soldiers of the Kwantung Army (Moscow : Veche, 2014) noting the timely character of the book on this little-studied subject, but is on many occasions critical of the work. According to the reviewer, the book in question makes an impression of a secondary one, and lacks sources; the author makes ungrounded conclusions and has a biased research approach, which is inappropriate for present-day historical studies.В рецензии, посвященной книге Е. В. Яковкина «Русские солдаты Квантунской армии» (М. : Вече, 2014), оценивается актуальность и малоизученность темы в российской историографии, но при этом высказываются многочисленные критические замечания. По мнению рецензента, монографии присущи вторичность, недостаточность источниковой базы, необоснованность выводов и предвзятость исследовательской позиции, особенно странная для современной исторической науки

Anomalous edge plasma transport, neutrals, and divertor plasma detachment

An impact of neutrals on anomalous edge plasma transport and zonal flow (ZF) is considered. As an example, it is assumed that edge plasma turbulence is driven by the resistive drift wave (RDW) instability. It is found that the actual effect of neutrals is not related to a suppression of the instability \textit{per se}, but due to an impact on the ZF. Particularly, it is shown that, whereas the neutrals make very little impact on the linear growth rate of the RDW instability, they can largely reduce the zonal flow generation in the nonlinear stage, which results in an enhancement of the overall anomalous plasma transport. Even though only RDW instability is considered, it seems that such an impact of neutrals on anomalous edge plasma transport has a very generic feature. It is conceivable that such neutral induced enhancement of anomalous plasma transport is observed experimentally in a detached divertor regime, which is accompanied by a strong increase of neutral density

A metric for robust model evaluation through text perturbations

This thesis introduces a new approach to improve robustness of text generative models by introduction of noise or text perturbations in prompts. A metric is developed to evaluate how well large language models perform when faced with noisy data. The efficiency of the approach is demonstrated experimentally by measuring models’ accuracy on controlled perturbations in 1200 questions from CommonsenseQA dataset. The result opens a new promising direction to evaluate and improve AI based solutions quality

Exact expectation values of local fields in quantum sine-Gordon model

We propose an explicit expression for vacuum expectation values of the exponential fields in the sine-Gordon model. Our expression agrees both with semi-classical results in the sine-Gordon theory and with perturbative calculations in the Massive Thirring model. We use this expression to make new predictions about the large-distance asymptotic form of the two-point correlation function in the XXZ spin chain.Comment: 18 pages, harvmac.tex, 2 figure

Correlators of the Jost functions in the Sine-Gordon model

In this paper the quantum direct scattering problem is solved for the Sine-Gordon model. Correlators of the Jost functions are derived by the angular quantization method.Comment: pp.1

On Electrostriction of a Granular Superconductor

Zero-temperature field-induced polarization, supercurrent density, and the related electrostriction (ES) of a granular superconductor are calculated within a model of 3D Josephson junction arrays. Both the "bulk-modulus-driven ES" (the change of the sample's volume in the free energy upon the applied stress) and the "change-of-phase ES" (due to the stress dependence of the weak-links-induced polarization) are considered. In contrast to magnetostriction of a granular superconductor, its electroelastic behavior is predicted to be dominated by the former contribution for all applied fields.Comment: REVTEX (epsf style), 3 EPS figure

Visual Modeling of Integrated Constructs in Mathematics As the Base of Future Teacher Creativity

Visual modeling concept of integrated constructs (essence) of mathematical objects in teacher training of humanistic area is presented as technology of education in problem solving. The main goal of innovative approach is student’s activity in mathematics on generating of concrete essence manifestations on concepts, methods, theorems, algorithms, procedures and so on. Such student’s activity should be: · Success in an area of actual interests and person’s experience and reached by perception; · Have high level of variability in visual modeling; · Success in domain of reflection process stimulation. Similar creative behavior of persons is typical for actors, dancing, and figure skating and so on. Now we show that such technology will be fruitful for teacher training in mathematics for humanistic specialties

Modeling of spectral and statistical properties of a random distributed feedback fiber laser

For the first time we report full numerical NLSE-based modeling of generation properties of random distributed feedback fiber laser based on Rayleigh scattering. The model which takes into account the random backscattering via its average strength only describes well power and spectral properties of random DFB fiber lasers. The influence of dispersion and nonlinearity on spectral and statistical properties is investigated. The evidence of non-gaussian intensity statistics is found
