Program for integrating multizonal photographs of the Earth, taken by MKF-6 camera, in a computer

An algorithm and program are described, for integrating up to 6 simultaneously exposed photographs in different spectral ranges of the surface of the Earth, taken by MKF-6 cameras aboard Soyuz-22. Three of the reference marks are identified on 1 photograph and then are used to integrate the other photographs with the first. The program was compiled for the ES-1040 computer, as a standard subprogram in a system for computer processing of data of study of the Earth from space

FPGA implementation of LTE turbo decoder using MAX-log MAP algorithm

© 2017 IEEE. Implementation of an efficient turbo decoder with low complexity, short delay and insignificant performance degradation is currently a quite challenging task. The paper presents an implementation of a 3GPP TS 36.212 LTE turbo decoder. The design of the turbo decoder has been optimized to achieve efficient FPGA resource utilization. This design can be useful for applications, which is critical to resource utilizations, but do not need high throughput

The architecture of it-environment for vocational education and training specialists in geoinformatics

© SGEM2017. All Rights Reserved. In this paper the approach to Information Educational Environment (IEE) creation is proposed. IEE is a complicated system that consists of a lot of hardware and software tools. Open architecture of the IEE provides integration of various electronic educational resources (virtual laboratories, virtual departments, electronic scientific-educational complexes). A variety of different hardware and software tools allow to create a variety of educational routes. In this paper we highlighted the main aspects about IEE creation. The composition and structure of the IEE is discussed. Experience of using the system is presented. The description of the curriculums, practical works, and laboratory tasks is given. The main component of the system is Electronic Scientific-Educational Complex “Geoinformation Technologies and Systems”. The Complex provides comprehensive support for research and educational activities in the field of Geoinformatics – from training sessions with the use of modern educational technologies to independent research work of students

Nuclear Quantum Effects in Water and Aqueous Systems: Experiment, Theory, and Current Challenges

Nuclear quantum effects influence the structure and dynamics of hydrogen-bonded systems, such as water, which impacts their observed properties with widely varying magnitudes. This review highlights the recent significant developments in the experiment, theory, and simulation of nuclear quantum effects in water. Novel experimental techniques, such as deep inelastic neutron scattering, now provide a detailed view of the role of nuclear quantum effects in water's properties. These have been combined with theoretical developments such as the introduction of the principle of competing quantum effects that allows the subtle interplay of water's quantum effects and their manifestation in experimental observables to be explained. We discuss how this principle has recently been used to explain the apparent dichotomy in water's isotope effects, which can range from very large to almost nonexistent depending on the property and conditions. We then review the latest major developments in simulation algorithms and theory that have enabled the efficient inclusion of nuclear quantum effects in molecular simulations, permitting their combination with on-the-fly evaluation of the potential energy surface using electronic structure theory. Finally, we identify current challenges and future opportunities in this area of research

Нейроэндокринная опухоль — параганглиома, симулирующая зоб

This paper presents two rare case reports with one common feature. Patients with thyroid nodules, who had undergone a comprehensive clinical evaluation based on standard algorithms according to their preoperative diagnosis of “Multinodular goiter, grade II”, were scheduled for surgical treatment (thyroidectomy). Postoperative morphological examination revealed, however, the extremely rare neuroendocrine tumor paraganglioma that simulated multinodular goiter with tracheal compression. Our analysis of these clinical cases showed common systematic mistakes that were committed during conventional, standardized preoperative examination, resulting in certain difficulties in the treatment of these patients.В данной статье представлены два редких клинических наблюдения, имеющих один объединяющий их признак. Пациентам с узловыми образованиями в щитовидной железе, обследованным в полном объеме согласно стандартным алгоритмам, с установленным до операции диагнозом «многоузловой зоб II степени», планировалось хирургическое лечение в объеме тиреоидэктомии. Однако после выполненных операций было установлено, что за многоузловой зоб с компрессией трахеи была ошибочно принята крайне редко встречающаяся нейроэндокринная опухоль — параганглиома, имитировавшая зоб с признаками компрессии органов шеи. При анализе клинических случаев нами были выявлены общие систематические ошибки, допущенные при обследовании с соблюдением общепринятых стандартизированных подходов, что привело к определенным сложностям в лечении этих пациентов

Роль радионуклидной диагностики в комплексном обследовании ВИЧ-инфицированных пациентов с ишемической болезнью сердца

Cardiovascular disease is one of the most frequent cause of death globally. The greatest part is occupied by ischemic heart disease. HIV patients are composed to a higher risk of coronary heart disease.The purpose of this work is to evaluate the possibility of using molecular imaging methods in a comprehensive examination of patients with HIV infection and ischemic heart disease.Materials and methods. The survey group includes 32 patients with HIV infection. The comparison group consists of 25 age-matched patients with coronary heart disease and without HIV Infection. All patients were underwent myocardial perfusion scintigraphy using single photon emission computed tomography. Positron emission tomography with FDG were performed if necessary to assess the viability of the myocardium. The patients of the main group undergo diagnostic coronary angiography and standard set of laboratory and institutional diagnostic methods.Results. The results of which confirm the high efficiency of radionuclide diagnostic methods for detecting perfusion disorders, contractility and myocardial viability in patients with HIV infection even at an early stage. They can be recommended for using in a comprehensive examination of patients with HIV infection.Наиболее частой причиной смертности во всем мире являются сердечно-сосудистые заболевания, среди которых ведущее место занимает ишемическая болезнь сердца (ИБС). В группу с наиболее высоким риском развития ИБС входят пациенты с ВИЧ-инфекцией.Цель исследования: оценка возможности применения методов молекулярной визуализации в комплексном обследовании пациентов с ВИЧ-инфекцией и ИБС.Материал и методы. В группу обследования включено 32 пациента с ВИЧ-инфекцией, группу сравнения составили 25 сопоставимых по возрасту пациентов без ВИЧ-инфекции с ИБС. Всем пациентам проведена перфузионная сцинтиграфия миокарда (с помощью ОФЭКТ), ПЭТ/КТ сердца с ФДГ проводилась при необходимости оценки жизнеспособности миокарда в комплексе с диагностической коронароангиографией и стандартным набором лабораторно-инструментальных методов диагностики.Результаты. Полученные результаты подтверждают высокую эффективностью методов радионуклидной диагностики для выявления нарушений перфузии, сократимости и жизнеспособности миокарда у пациентов с ВИЧ-инфекцией даже на ранней стадии и могут быть рекомендованы к использованию в комплексном обследовании пациентов с ВИЧ-инфекцией
