Factorization problem with intersection

We propose a generalization of the factorization method to the case when $\mathcal{G}$ is a finite dimensional Lie algebra such that $\mathcal{G}=\mathcal{G}_0\oplus M \oplus N$ (direct sum of vector spaces), where $\mathcal{G}_0$ is a subalgebra in $\mathcal{G}$, $M, N$ are $\mathcal{G}_0$-modules, and $\mathcal{G}_0 +M$, $\mathcal{G}_0 +N$ are subalgebras in $\mathcal{G}$. In particular, we consider the case when $\mathcal{G}$ is a $\Z$-graded Lie algebra. Using this generalization, we construct some top-like systems related to the algebra $so(3,1)$. According to the general scheme, these systems can be reduced to linear systems with variable coefficients. For the top-like systems first integrals and infinitesimal symmetries are found

ANALYSIS OF THE CHEMICAL COMPOSITION OF CHAROITE ROCKS

The unique charoite mineralization, established on the Murun alkaline massif in the northwestern part of the Aldan shield on the border of the Irkutsk region and Yakutia, is still of great interest to some of researchers (geologists, crystallographers, geochemists, etc.). The outcrops of charoite-bearing rocks at the “Sirenevyi Kamen” deposit are noted both in the indigenous outcrops and in eluvial clatters [Bondarenko, 2009].The unique charoite mineralization, established on the Murun alkaline massif in the northwestern part of the Aldan shield on the border of the Irkutsk region and Yakutia, is still of great interest to some of researchers (geologists, crystallographers, geochemists, etc.).

Search for glitches of gamma-ray pulsars with deep learning

The pulsar glitches are generally assumed to be an apparent manifestation of the superfluid interior of the neutron stars. Most of them were discovered and extensively studied by continuous monitoring in the radio wavelengths. The Fermi-LAT space telescope has made a revolution uncovering a large population of gamma-ray pulsars. In this paper we suggest to employ these observations for the searches of new glitches. We develop the method capable of detecting step-like frequency change associated with glitches in a sparse gamma-ray data. It is based on the calculations of the weighted H-test statistics and glitch identification by a convolutional neural network. The method demonstrates high accuracy on the Monte Carlo set and will be applied for searches of the pulsar glitches in the real gamma-ray data in the future works.Comment: 4 pages, 5 figure

The theory of traces for systems with nondeterminism and probability

This paper studies trace-based equivalences for systems combining nondeterministic and probabilistic choices. We show how trace semantics for such processes can be recovered by instantiating a coalgebraic construction known as the generalised powerset construction. We characterise and compare the resulting semantics to known definitions of trace equivalences appearing in the literature. Most of our results are based on the exciting interplay between monads and their presentations via algebraic theories

The earliest spectroscopy of the GRB 030329 afterglow with 6-m telescope

The earliest BTA (SAO RAS 6-m telescope) spectroscopic observations of the GRB 030329 optical transient (OT) are presented, which almost coincide in time with the "first break" ($t\sim 0.5$ day after the GRB) of the OT light curve. The beginning of spectral changes are seen as early as $\sim 10-12$ hours after the GRB. So, the onset of the spectral changes for $t<1$ day indicates that the contribution from Type Ic supernova (SN) into the OT optical flux can be detected earlier. The properties of early spectra of GRB 030329/SN 2003dh can be consistent with a shock moving into a stellar wind formed from the pre-SN. Such a behavior (similar to that near the UV shock breakout in SNe) can be explained by the existence of a dense matter in the immediate surroundings of massive stellar GRB/SN progenitor). The urgency is emphasized of observation of early GRB/SN spectra for solving a question that is essential for understanding GRB physical mechanism: {\it Do all} long-duration gamma-ray bursts are caused by (or physically connected to) {\it ordinary} core-collapse supernovae? If clear association of normal/ordinary core-collapse SNe (SN Ib/c, and others SN types) and GRBs would be revealed in numbers of cases, we may have strong observational limits for gamma-ray beaming and for real energetics of the GRB sources.Comment: 4 pages, 5 figures.

Introduction of new skill «in-service trainer» in WorldSkills Rrussia

The aim of the study is to find out new and effective teaching tools and technologies that enhance the training level of in-service trainers. As one of these tools, the development of competitive movement is offered, which actively engages students into the professional work.Methods. The comprehensive assessment of the scope of secondary vocational education and training (VET) and comparative analysis of professional skills contests in Russian regions with the aim to identify existing organizational and competitive challenges are provided. Results. On the basis of these studies, the positive effect of training of in-service trainers on the use of professional skills contests is outlined. Scientific novelty. Integration of in-service training at all levels of training – from students to experienced workers into receivership motion would allow us to create a creative learning environment, promoting active self-development group of training of vocational trainers in general. Practical significance. The research results can be useful to teachers of secondary and postsecondary VET institutions in the further study of the organizational and creative foundations of training of in-service trainersЦель изложенного в статье исследования заключается в поиске новых эффективных педагогических инструментов и технологий, обеспечивающих повышение уровня подготовки мастеров производственного обучения. В качестве одного из таких инструментов предлагается развитие конкурсного движения, активно вовлекающего обучающихся в профессиональное творчество. Методы, использовавшиеся в работе, – комплексная оценка состояния сферы среднего профессионального образования (СПО), сравнительный анализ конкурсов профессионального мастерства регионов России с целью определения существующих организационно-конкурсных проблем. Результаты. Убедительно доказывается положительный эффект проведения конкурсов профессионального мастерства педагогов производственного обучения. Данные мероприятия способствуют реабилитации в настоящее время не слишком, к сожалению, престижной, по мнению многих, специальности педагога, занимающегося обучением будущих рабочих; конкурсы развивают профессиональную компетентность и важные в современных реалиях личностные качества: мобильность, активность, готовность к самосовершенствованию. Научная новизна. По мнению авторов, интегрирование мастеров производственного обучения всех уровней профессиональной подготовки – от студентов до опытных работников – в конкурсное движение позволяет создавать творческую образовательную среду, способствующую активному саморазвитию профессионального сообщества мастеров производственного обучения. Практическая значимость. Результаты исследований могут быть полезны преподавателям организаций среднего профессионального образования при дальнейшем исследовании организационно-творческих форм и методов подготовки мастеров производственного обучени
