The paper presents a method for detecting false responses of localization and identification algorithms. The method considers matching image characteristics that cannot be described by local features stably and completely. It is proposed to use image zones containing such features, describe them and use them to assess the validity of the algorithm response. In the work we demonstrate how the algorithm works on ID documents. Possible features are images of the coats of arms and flags of countries, background filling and text unique to the considered document type. To illustrate the proposed algorithm, the MIDV-500 and MIDV-LAIT datasets were taken. The first is used to show that the rejector does not reject correct system responses, the second - that it rejects the incorrect ones. We test several methods of zone description. The experimental results show that false type selection decreases with the use of any description type and the local CNN-descriptor shows the best performance. The increase of classes with marked zones is shown to improve the filtration of false responses. The experiments show the improvement from by 13% with one type with zones to by 4 times with 10 types.

This article examines Russian culturonyms in contemporary American literature. American authors come from a variety of linguistic and cultural backgrounds, and their literary works often reflect translingual and/or transcultural features. The relevance of this article is owed to the expanding study of bilingual creativity among bilingual and bicultural individuals. Bilingual authors, who are also heritage language speakers, often possess linguacultural hybridity because they were raised with several languages and cultures. It is in their fiction writing that this hybridity is often expressed. The aim of this work is to reveal and analyze culture-specific words from Russian medieval linguaculture found in literary works of Nicholas Kotar and Olesya Salnikova-Gilmore, American writers of Russian descent. The bilingual heritage writers often opt for internal translation to describe Russian culturonyms to English-speaking readers. By doing so, bilingual and bicultural writers of Russian heritage introduce and familiarize English speakers with elements of Russian linguaculture. This, in turn, further contributes to the growing English-Russian contact in transcultural literature. In their English-language novels, Kotar and Salnikova-Gilmore skillfully incorporate and adapt Russian culture-specific words and concepts. The findings may provide insight into contemporary literary works written by bilingual heritage writers and their linguacultural hybridity, including the translation strategies implemented in their original interlinguacultural texts.

Vehicles represent a source of increased danger, and therefore any issues related to ensuring safety in this area are of particular practical importance, because they carry a significant risk of adverse consequences both for society as a whole and for its individuals. However, in the science of labor law, there is currently no complete and comprehensive study devoted to medical examinations of workers of various modes of transport from the perspective of the scope of their activities and the characteristics of the labor function that they perform. The purpose of the study is to formulate the problems of legal regulation of medical examinations of workers related to transport traffic, as well as to identify trends in legal regulation in this area, in particular in the context of the development of high-speed traffic. Currently, the legal regulation of the procedure for conducting medical examinations of workers is not uniform since it is regulated by a large number of by-laws of various ministries and departments, and the introduction of telemedicine technologies in the field of protecting the health of citizens is perceived ambiguously by various departments. I believe that in this situation it is necessary to adopt a universal regulatory act, which should apply to all transport workers without exception, regardless of its type, should reflect the conceptual requirements for the procedure for conducting medical examinations, including listing cases in which the use of remote, digital technologies. Based on this act, departmental acts should already be formed regulating the procedure for undergoing medical examinations in relation to workers of certain types of transport. Such a solution to the issue will make it possible to formulate a uniform approach to conducting medical examinations, taking into account the specifics of modes of transport, thereby facilitating not only law enforcement practice, but also more quickly making changes to this act, which is especially important in the context of the development of digital technologies.

Preservation and promotion of public health by increasing the availability and quality of high-tech medical care is one of the priorities of the state policy [1]. In the current situation, great importance is given to the foundation of modern trauma and orthopedic departments focusing on the treatment of various pathologies of motor functions. The research objective is to highlight modern possibilities of the traumatology and orthopedics department of the in-patient department of N.A. Semashko Northern Medical Clinical Center.

Materials and methods: the materials used were official statistics data from the annual reports of the head of the traumatology and orthopedics department of the N.A. Semashko Center. Results and discussion: hundreds of large joint endoprosthetic surgeries are annually performed in the traumatology and orthopedic department of the Semashko Center’s in-patient department. Physicians are proficient in the technique of unicondylar prosthetics, successfully use dual mobility systems for complex revision endoprosthetics, and use special trabecular tantalum structures to replace extensive bone defects.

Conclusion: with respect to the complexity of performed surgical interventions, the department matches federal clinics, and many operations performed by specialists of the department are rare even in metropolitan medical centers because of their complexity and cost.

The article is devoted to Memorial Day of the organizer and the fi rst rector of PGUPS Augustine Betancourt

В работе рассматривается предобусловливатель блочного неполного обратного треугольного разложения первого порядка “по значению” BIIC-IC1 для решения систем линейных алгебраических уравнений с симметричной положительно определенной матрицей. Рассматривается способ применения MPI+OpenMP технологии для построения и обращения предобусловливателя BIIC-IC1, при этом в предобусловливателе число блоков кратно числам используемых процессоров и используемых потоков. Предлагается способ применения MPI+OpenMP технологии для построения и обращения предобусловливателя BIIC-IC1, в котором для применения OpenMP технологии используется специальное упорядочение узлов сетки внутри подобластей, соответствующих расчетам на процессорах. Проводится сравнение времени решения задач методом сопряженных градиентов с предобусловливателем BIIC-IC1 с использованием MPI и гибридной MPI+OpenMP технологии на примере модельной задачи и ряда задач из коллекции разреженных матриц SuiteSparse.

The convection-diffusion equation with dominant convection is considered on a uniform grid of central difference scheme. The multigrid method is used for solving the strongly nonsymmetric systems of linear algebraic equations with positive definite coefficient matrices. Two-step skew-Hermitian iterative methods are utilized for the first time as a smoothing procedure. It is demonstrated that using the proper smoothers enables to improve the convergence of the multigrid method. The robustness of the smoothers with respect to variation of the Peclet number is shown by local Fourier analysis and numerical experiments.
