Methods and software tools of morphological disambiguation in the texts in tatar
© Research India Publications. This article provides a review of analytical methods for resolving the problem of morphological ambiguity and analysis of their applicability to the Tatar language. Since the task was set still in the 50-60-ies of XX century, the methods of solution have been accumulated quite a lot. Basically they can be divided into methods of rule-based and statistical and probabilistic methods. Methods are mainly language independent, each has its advantages and disadvantages, and their accuracy varies from one language to another. For example, for the English language, which has a poor morphology and the fixed order of the words, the accuracy reaches 94-96%. And for the Russian language with free word order, such accuracy is difficult. To resolve the ambiguity in morphological Tatar language in terms of the characteristics of the language such as agglutinative feature and free word order, it is offered a fusion of these methods, by which a high precision resolution is supposed to be achieved. At the moment, the research is still in progress, the tools for the development of contextual rules have been designed, subcorpus for statistical machine learning and probabilistic models is also being elaborated. In addition to the methods, the article describes the current state of the electronic corpus of the Tatar language, and discusses the problems and possible solutions to the problem of polysemanticism in the corpus markings
Iranian Influence on the Urals in the Early 21st Century
The article was submitted on 19.04.2017.В начале XXI века Иран стал активно стремиться к расширению своего присутствия в разных регионах России. Тегеран начал активно налаживать экономические, культурные и научно-образовательные связи с отдельными регионами Российской Федерации. Подобная интенсификация отношений вызвана экономическими санкциями, в которых оказался Иран из-за своей ядерной программы, поэтому Тегеран стремится расширить свои связи с регионами, не представлявшие интереса ранее. Среди них – Урал, имеющий большой промышленный и научно-образовательный комплекс. В статье автор анализирует влияние Ирана на Урал в первые два десятилетия XXI века.At the beginning of the 21st century, Iran has actively sought to expand its presence in various regions of Russia. Teheran began actively to establish economic, cultural and scientificeducational ties with individual regions of the Russian Federation. Such an intensification of relations is caused by the economic sanctions in which Iran found itself because of It has its own nuclear program. Therefore, Tehran seeks to expand its ties with those regions that previously had no interest for it. Among such interest for Iran is the Urals, which has a large industrial and scientific-educational complex. In the article the author analyzes the influence of Iran on the Urals in the first two decades of the XXI century
Context-Based Rules for Grammatical Disambiguation in the Tatar Language
© 2017, Springer International Publishing AG. The paper is dedicated to the problem of grammatical ambiguity in the Tatar National Corpus and describes the methodology and software used for automation of the disambiguation process. Grammatical ambiguity is widely represented in agglutinative languages like Turkic or Finno-Ugric. Disambiguation in the corpus is based on the context-oriented classification of ambiguity types which has been carried out on corpus data in the Tatar language for the first time. In this study the corpus is used as a source for the research and at the same time as a destination for implementing the results. The grammatical ambiguity types are detected automatically using the finite-state morphological analyzer and then classified. In order to build up the grammatically disambiguated subcorpus, a special software module was developed. It searches for ambiguous tokens in the corpus, collects statistical information and allows creating and implementing the formal context-based disambiguation rules for different ambiguity types
Search for a Signal on QCD Critical Point in Central Nucleus-Nucleus Collisions
We discuss that the QCD critical point could appear in central collisions in
percolation cluster. We suggest using the nuclear transparency effect and the
one of the light nuclear production to identify the critical point.Comment: To appear in the proceedings of the 20th International Conference on

DIFFERENTIAL SENSITIVITY AS THE BASIS OF PERSONALITY
The differential sensitivity in different analyzers is analyzed as a basic basis for the success of mastering various professions. An integrated basic ability was experimentally revealed as a result of the interaction between sensitivity in the auditory, visual, motor analyzers, as well as emotional sensitivity. The hypothesis about the relationship between sensitivity and personal characteristics has been confirmed, which in practical terms makes it possible to use the results of the study to develop recommendations for professional selection, career selection, and career guidance.Анализируется дифференциальная чувствительность в разных анализаторах как базовая основа для успешности освоения различных профессий. Экспериментально выявлена интегрированная базовая способность как результат взаимодействия между чувствительностью в слуховом, зрительном, двигательном анализаторах, а также эмоциональной чувствительностью. Подтверждена гипотеза о связи чувствительности с личностными характеристиками, что в практическом плане дает возможность использовать результаты исследования для разработки рекомендаций по профотбору, профподбору, профориентации
Scintillation Light Detection with MAPD-3NK and MPPC-S12572-010P Readout
The linearity and energy resolution of two different solid-state photomultipliers (SiPMs) has been studied with reading out the LFS-8 scintillator (3x3x10 mm3). First SiPM (MAPD-3NK) from Zecotek Photonics consists of deeply burned pixels (cells) and has an active area of 3.7x3.7 mm2. The second one (MPPC-S12572-010P) from Hamamatsu has a surface cell structure and an active area of 3x3 mm2. Both SiPMs have the same pixel density of 10000 mm−2. Energy resolution and linearity of the SiPMs has been studied in the energy range of 59.6-1275 keV. It is found that both SiPMs demonstrate good linearity of signal amplitude as a function of the gamma ray energy in the studied energy range. The detector based on the MAPD-3NK provides significantly good energy resolution in comparison to the detector based on the MPPC-S12572-010P
Humus state of buried soils of different age archaeological monuments on the territory of Ufa (Russia, Republic of Bashkortostan)
The paper studies the humus state of buried soils on the territory of archaeological monuments: the New-Ufa Burial Ground (early Iron Age) and the Settlement Ufa-II (early Middle Ages), located in the urban district of Ufa (Russia, Republic of Bashkortostan). The soil cover of archaeological monuments is represented by Greyzemic Phaeozem over Grayzemic Phaeozem (gz-PH over gz-PH). The humus content in buried horizons is 2.06-5.26%, which is 2-4 times less in comparison with the native soil. There are two types of humus such as humate and humate-fulvate. Among humic acids, the fraction associated with calcium (HAs-2) predominates. The spectral curves of humic acids HAs-2 at different wavelengths for the buried humus-accumulative horizon of the New-Ufa Burial Ground have a steeper character and lower optical density values compared to the background soil. The spectral curves of the buried horizons of the Settlement Ufa-II have flatter disposition and, in terms of optical density, are close to the values of the native soil. Obtained results make it possible to estimate the transformation of organic matter in the soils after their burial in comparison with the modern native soil Greyzemic Phaeozem (gz-PH) of the city park. © Published under licence by IOP Publishing Ltd.Russian Foundation for Basic Research, РФФИ, (20-33-90107)This research was funded by the Russian Foundation for Basic Research (grant 20-33-90107)
First hours of the GRB 030329 optical afterglow
We present the first results of the observations of the extremely bright
optical afterglow of gamma-ray burst (GRB) 030329 with the 1.5m Russian-Turkish
telescope RTT150 (TUBITAK National Observatory, Bakyrlytepe, Turkey). RTT150
was one of the first 1.5m-class telescopes pointed to the afterglow.
Observations were started approximately 6 hours after the burst. During the
first 5 hours of our observations the afterglow faded exactly as a power law
with index -1.19+-0.01 in each of the BVRI Bessel filters. After that, in all
BVRI filters simultaneously we observe a steepening of the power law light
curve. The power law decay index smoothly approaches the value ~= -1.9,
observed by other observatories later. This power law break occurs at t-t_0
=0.57 days and lasts for +-0.1 days. We observe no variability above the
gradual fading with the upper limits 10--1% on time scales 0.1--1000s. Spectral
flux distribution in four BVRI filters corresponds to the power law spectrum
with spectral index \alpha=0.66+-0.01. The change of the power law decay index
in the end of our observations can be interpreted as a signature of collimated
ultrarelativistic jet. The afterglow flux distribution in radio, optical and
x-rays is consistent with synchrotron spectrum. We continue our observations of
this unique object with RTT150.Comment: Astronomy Letters, Vol. 29, No. 9, p. 573; 6 pages, 5 figures;
