СОВРЕМЕННЫЕ МЕТОДЫ АВТОМАТИЧЕСКОГО ОБНАРУЖЕНИЯ ПРЯМОУГОЛЬНЫХ ОБЪЕКТОВ НА ИЗОБРАЖЕНИЯХ

Low-level and high-level feature extraction methods and algorithms for the image formation of a rectangular object were considered. The algorithm for object detection based on correlation analysis, as well as the algorithm containing the use of Canny edge detector, Hough and Radon transform for lines detection, and then, depending on the properties of the object lines combining in the rectangular area, were explored. The algorithms were tested on the base of 1000 passports for the problem of accurate photo edges detection.Рассмотрены низкоуровневые и высокоуровневые методы выделения признаков на изображении и алгоритмы формирования прямоугольного объекта.

How unique is the Asymptotic Normalisation Coefficient (ANC) method?

The asymptotic normalisation coefficients (ANC) for the vertex $^{10}$B $\to$ $^9$Be + p is deduced from a set of different proton transfer reactions at different energies. This set should ensure the peripheral character of the reaction and availability of data for the elastic channels. The problems associated with the characteristics of the data and the analysis are discussed. For a subgroup of the set of available data, the uniqueness property of the extracted ANC is fulfilled. However, more measurements are needed before a definite conclusion can be drawn.Comment: 19 pages, 11 figures, to be published in Phys Rev

Results of different kinds of carotid endarterectomy in patients with and without type 2 diabetes mellitus

BACKGROUND: Type 2 diabetes mellitus (DM) is one of the important markers for the development of adverse cardiovascular events after carotid endarterectomy (CEE). However, studies on this issue are based on small sample of patients and do not take into account the type of surgery as an additional factor of potentially negative impact on the course of the postoperative period.AIM: Analysis of hospital and long-term results of eversion and classical CEE with plastic surgery of the reconstruction zone with a biological patch in patients with type 2 diabetes and without it.MATERIALS AND METHODS: In this multicenter retrospective study from January 2010 to December 2020. included 5731 patients. Depending on the presence / absence of type 2 diabetes and the type of implemented CEE, 4 groups were formed: group 1 — 12.2% (n = 702) — patients with type 2 diabetes and eversion CEE; Group 2 — 55.0% (n = 3153) patients without type 2 diabetes and eversion CEE; Group 3 — 8.5% (n = 484) patients with type 2 diabetes and classical CEE; Group 4 — 24.3% (n = 1392) patients without type 2 diabetes and classical CEE. The duration of postoperative follow-up was 78.6 ± 39.2 months.RESULTS: At the long-term follow-up stage, patients with type 2 diabetes after the classical surgical technique demonstrated the highest rates of all types of complications: death (p <0.0001), MI (p = 0.011), ischemic stroke (p <0.0001), restenosis / occlusion of the ICA (p <0.0001), combined end point (p <0.0001). At the same time, the group of eversion CEE with impaired carbohydrate metabolism took the second position in terms of the prevalence of adverse events. These circumstances demonstrate that patch implantation is accompanied by an increased risk of developing not only myocardial infarction, but also restenosis of the reconstruction zone, as well as the associated ischemic stroke, which was demonstrated by our results.CONCLUSION: Patients with type 2 diabetes and a history of CEE are at increased risk of ischemic stroke at the hospital stage of observation and all unfavorable cardiovascular conditions (death, myocardial infarction, ischemic stroke, restenosis or ICA occlusion in the reconstruction zone) in the long-term postoperative period

Peculiarities of the effect of climato - geographic factors on the emergence of acute disturbances of the cerebral circulation in residents of the far north

This article presents a study of the patterns of stroke detection in the High North, depending on the periodization of the polar day and night. 2264 SMP phone cards of the 1101 year form for the period from 2012 to 2018 were selected and studied. The correlation was estimated by nationality, gender, age, social status. Comparison of results depending on the periodization of light and heliomagnetic activity was conducted. The study identified the main group of the visiting group of women who are most prone to stroke. The average age was 56 years for the visiting population and 66 years for the indigenous population. The greatest number of strokes occurred during the polar day. Overvoltage occurs due to excessive insolation against the. background of a deficit of a dark period of the day, which directly affected the decrease in melatonin levels and an increase in the content of stress hormones.В данной статье представлено изучение закономерности выявления инсультов у жителей Крайнего Севера в зависимости от периодизации полярного дня и ночи. Производилась выборка и исследование 2264 карт вызовов СМП формы 110/у за период с 2012 по 2018 год. Оценивалась корреляция по национальной принадлежности, полу, возрасту, социальному статусу. Сопоставление результатов в зависимости от световой периодизации и гелиомагнитной активности. В ходе исследования выявлена основная группа приезжего населения, женского пола, которая наибольше была подвержена возникновению инсульта. Средний возраст составил 56 лет у приезжего населения и 66 лет у коренного. Наибольшее количество инсультов происходило в период полярного дня. Состоянием перенапряжения возникало вследствии избыточной инсоляции на фоне дефицита темного периода суток, что непосредственно влияло на снижение уровня мелатонина и повышения содержания стрессорных гормонов

Ten-year long-term outcomes of conventional and eversion carotid endarterectomy. Multicenter study

Aim. To analyze the immediate and long-term outcomes of eversion and conventional carotid endarterectomy (CE) with patch angioplasty.Material and methods. For the period from February 1, 2006 to September 1, 2021, the present retrospective multicenter open comparative study included 25106 patients who underwent CE. Depending on the technique of operation, the following groups were formed: group 1 (n=18362) — eversion CE; group 2 (n=6744) — conventional CE with patch angioplasty. The long-term follow-up period was 124,7±53,8 months.Results. In the hospital postoperative period, the groups were comparable in incidence of all complications: lethal outcome (group 1: 0,19%, n=36; group 2: 0,17%, n=12; p=0,89; odds ratio (OR) =1,1; 95% confidence interval (CI) =0,57- 2,11); myocardial infarction (MI) (group 1: 0,15%, n=28; group 2: 0,13%, n=9; p=0,87; OR=1,14; 95% CI=0,53-2,42); stroke (group 1: 0,33%, n=62; group 2: 0,4%, n=27; p=0,53; OR=0,84; 95% CI=0,53-1,32); bleeding with hematoma formation (group 1: 0,39%, n=73; group 2: 0,41%, n=28; p=0,93; OR=0,95; 95% CI=0,61-1,48); internal carotid artery (ICA) thrombosis (group 1: 0,05%, n=11; group 2: 0,07%, n=5, p=0,9; OR=0,8; 95% CI=0,28-2,32). In the long-term follow-up, the groups were comparable only in MI incidence: group 1: 0,56%, n=103; group 2: 0,66%, n=45; p=0,37; OR=0,84; 95% CI=0,59-1,19. All other complications were more frequent after conventional CE with patch angioplasty: all-cause death (group 1: 2,7%, n=492; group 2: 9,1%, n=616; p<0,0001; OR=0,27; 95% CI=0,24-0,3); lethal ischemic stroke (group 1: 1,0%, n=180; group 2: 5,5%, n=371; p<0,0001; OR=0,17; 95% CI=0,14-0,21); non-lethal ischemic stroke (group 1: 0,62%, n=114; group 2: 7,0%, n=472; p<0,0001; OR=0,08; 95% CI=0,06-0,1); ICA restenosis >60%, requiring re-revascularization (group 1: 1,6%, n=296; group 2: 12,6%, n=851; p<0,0001; OR=0,11; 95% CI=0,09-0,12). Thus, the composite endpoint (lethal ischemic stroke + non-lethal ischemic stroke + MI) after conventional CE with patch angioplasty was more than 6 times higher than this parameter of eversion CE: group 1: 2,2%, n=397; group 2: 13,2%, n=888; p<0,0001; OR=0,14; 95% CI=0,12-1,16.Conclusion. Conventional CE with patch angioplasty is not prefer for cerebral revascularization in the presence of hemodynamically significant ICA stenosis due to the high prevalence of deaths, stroke, and ICA restenosis in the long-term follow-up
