INTEGRATION OF THE FOOD INDUSTRY AND RELATED SECTORS BASED ON THE CLUSTER APPROACH

In a diversified agro-industrial complex structure of the Voronezh region there are more than 200 enterprises of food and processing industry. However, due to the growth disparity in prices for agricultural and industrial products, the collapse of a single process has been a sharp decline in the production of final products of agribusiness. In the conditions of Russia's accession to the WTO and the growth in this regard competition in the market of raw materials and finished products, problems of high relevance of search for effective strategies for the development of the food industry. The emphasis of these reforms should be a priori biased towards the crea tion of favorable conditions for the formation of optimal institutional innovation structures and prospects of development of the national agro-food system at all levels. In this regard, the formation of institutional models of integration in the agricultural sector, we regard the system approach, where the newly created integrated structure is defined as a social institution, characterized by composition, structure, objectives, functions, internal and external bounding box defined inputs and outputs. Under these conditions, there is a need to develop partnerships and coo peration between enterprises of the technological chain of the final product agribusiness, finds its expression in a variety of forms, one of which is the formation of clusters, creating the conditions for effective interaction of producers of raw materials and finished products, research and educational institutions, service infrastructure of organizations and representatives of other areas to ensure. However, the analysis showed that, across a variety of alternative strategies for the development of the food industry, the most optimal in today's economic conditions appear to integration strategies that involve the union of disparate market participants on the principles of economic integr ation, which results in a synergy by eliminating irrational mediation

Visual Affect Around the World: A Large-scale Multilingual Visual Sentiment Ontology

Every culture and language is unique. Our work expressly focuses on the uniqueness of culture and language in relation to human affect, specifically sentiment and emotion semantics, and how they manifest in social multimedia. We develop sets of sentiment- and emotion-polarized visual concepts by adapting semantic structures called adjective-noun pairs, originally introduced by Borth et al. (2013), but in a multilingual context. We propose a new language-dependent method for automatic discovery of these adjective-noun constructs. We show how this pipeline can be applied on a social multimedia platform for the creation of a large-scale multilingual visual sentiment concept ontology (MVSO). Unlike the flat structure in Borth et al. (2013), our unified ontology is organized hierarchically by multilingual clusters of visually detectable nouns and subclusters of emotionally biased versions of these nouns. In addition, we present an image-based prediction task to show how generalizable language-specific models are in a multilingual context. A new, publicly available dataset of >15.6K sentiment-biased visual concepts across 12 languages with language-specific detector banks, >7.36M images and their metadata is also released.Comment: 11 pages, to appear at ACM MM'1

Cosmological zoo -- accelerating models with dark energy

ecent observations of type Ia supernovae indicate that the Universe is in an accelerating phase of expansion. The fundamental quest in theoretical cosmology is to identify the origin of this phenomenon. In principle there are two possibilities: 1) the presence of matter which violates the strong energy condition (a substantial form of dark energy), 2) modified Friedmann equations (Cardassian models -- a non-substantial form of dark matter). We classify all these models in terms of 2-dimensional dynamical systems of the Newtonian type. We search for generic properties of the models. It is achieved with the help of Peixoto's theorem for dynamical system on the Poincar{\'e} sphere. We find that the notion of structural stability can be useful to distinguish the generic cases of evolutional paths with acceleration. We find that, while the $\Lambda$CDM models and phantom models are typical accelerating models, the cosmological models with bouncing phase are non-generic in the space of all planar dynamical systems. We derive the universal shape of potential function which gives rise to presently accelerating models. Our results show explicitly the advantages of using a potential function (instead of the equation of state) to probe the origin of the present acceleration. We argue that simplicity and genericity are the best guide in understanding our Universe and its acceleration.Comment: RevTeX4, 23 pages, 10 figure

Оценка риска желудочно-кишечного кровотечения у пациентов с повреждением головного мозга

The aim of the study was to develop a risk model for upper gastrointestinal tract (GIT) bleeding in patients with brain injury of various etiologies.Material and methods. Case histories of 33 patients were included into a retrospective descriptive study: 22 patients had severe brain injury of various etiologies, and 11 patients after elective surgery for cerebral aneurisms with uneventful postop period were taken for comparison. The patients were grouped in two arms: Group 1 included patients with obvious signs of GIT bleeding (N=11) and Group 2 had no obvious signs of bleeding (N=22). Complaints, life and medical history, comorbidities, specialists’ exams data, results of laboratory and instrumental examinations, therapeutic regimens were analyzed. Presence of disproportionate pathologic sympathetic overreaction to acute brain injury, i.e., paroxysmal sympathetic hyperactivity (PSH), was assessed on admission and on Days 1, 3 and 5 after brain injury. Results. A model for upper GIT bleeding risk assessment was designed using logistic regression. The resulting model gains high quality rating: χ²=33,78, 3; p<0,001; OR=315. The risk of upper GIT bleeding exceeded 95% in patients having combination of 4 symptoms in their medical history (presence of PSH on Day 1 after acute brain injury; Karnofsky performance scale index 75; lack of neurovegetative stabilization in the acute period of brain injury; gastric and/or duodenal ulcer).Conclusion. Determining the risk factors thresholds enables stratification of patients by the risk for upper GIT bleeding. Modification of the identified four risk factors (presence of PSH on Day 1after acute brain injury; Karnofsky performance scale index 75; lack of neurovegetative stabilization in the acute period of brain injury; gastric and/or duodenal ulcer) will probably reduce the occurrence of upper GIT bleeding in patients with acute brane injury of various etiology.Цель исследования — построение модели риска развития желудочно-кишечного кровотечения из желудка и двенадцатиперстной кишки у пациентов с повреждением головного мозга различной этиологии. Материал и методы. В ретроспективное описательное исследование включили истории болезни 33-х пациентов: 22 пациентов — с тяжелым повреждением головного мозга различной этиологии и, для сравнения, 11 пациентов — с аневризматической болезнью сосудов головного мозга с неосложненным течением послеоперационного периода после плановых нейрохирургических вмешательств. Всех пациентов разделили на 2 группы: с явными признаками кровотечения из ЖКТ (n=11) и без явных признаков кровотечения (n=22). Проанализировали жалобы, анамнез заболевания и жизни, сопутствующие заболевания, данные осмотров специалистов, результаты лабораторных и инструментальных исследований, особенности терапии. Функции вегетативной нервной системы оценивали по проявлениям пароксизмальной симпатической гиперактивности (ПСГА) при поступлении в стационар, на 1-е, 3-и и 5-е сут после повреждения ГМ. Результаты. Средствами логистической регрессии построили модель оценки риска развития явного кровотечения из верхних отделов желудочно-кишечного тракта. Полученная модель обладает высокой оценкой качества: χ²=33,78, 3; p<0,001; OR=315. При сочетании в анамнезе 4-х признаков (повышение ПСГА в 1-е сут после повреждения головного мозга; индекс Карновского менее 75; отсутствие нейровегетативной стабилизации в остром периоде повреждения головного мозга; язвенная болезнь желудка и двенадцатиперстной кишки (ДПК)) риск развития явного кровотечения из верхних отделов желудочно-кишечного тракта превышал 95%.Заключение. Выделение пороговых значений факторов риска позволяет разделить пациентов на группы риска развития кровотечений из верхних отделов ЖКТ. Воздействие на выявленные 4 фактора риска (проявления ПСГА в 1-е сут после повреждения головного мозга; индекс Карновского менее 75; отсутствие нейровегетативной стабилизации в остром периоде повреждения головного мозга; язвенная болезнь желудка и ДПК) позволит, вероятно, снизить частоту ЖКК из верхних отделов ЖКТ у пациентов с повреждением ГМ различной этиологии.

Surfactant therapy for pneumonia COVID-19 of obstetric patients

Introduction. Pregnant women may be at increased risk for severe COVID-19 illness. Pregnant women are more likely to be hospitalized at ICU, needed the mechanical ventilation compared to nonpregnant women of childbearing age. Building on the experience of the effective use of the exogenous surfactant for influenza A/H1N1 treatment of pregnant women with COVID-19, the surfactant therapy has also been included in the treatment.The objective. To evaluate the effectiveness of surfactant therapy in the integrated treatment of severe COVID-19 pneumonia of pregnant women and postpartum women.Materials and methods. The study included 135 pregnant and postpartum women with severe COVID-19 pneumonia. All of them received antiviral, anticoagulant, anticytokine and anti-inflammatory therapy. 68 patients (main group) with an initially more severe course of the disease and a greater degree of lung damage (p = 0.026) received inhalations with Surfactant-BL, 67 patients (control group) did not receive the  surfactant therapy. Patients received Surfactant-BL through a  mesh-nebulizer at a  dose of 75 mg 2 times a day for 3–5 days.Result. Patients of the main group showed decreasing risks of requiring the noninvasive ventilation (27.9% vs. 52.2%, р = 0.014) and artificial lung ventilation (2.9% vs. 11.9%, p = 0.047), the length of stay in the intensive care unit (ICU) was reduced (10.6 vs. 13.1 inpatient days, р = 0.045). Сomplications such as pneumomediastinum and pneumothorax occurred less frequently in the surfactant therapy group (24.2% vs. 52.4%, p = 0.037) with a high extent of lung damage (CT-3–4). With early surfactant therapy in the standard oxygen therapy stage or high-flow oxygenation, gas exchange indicators were restored faster, thus avoiding mechanical ventilation and has reduced the duration of intensive care (р = 0.004) and prevented deaths.Conclusion. The use of surfactant therapy for pneumonia associated with COVID-19 in pregnant and postpartum women against the background of ongoing complex therapy helps to prevent further lung damage, reduce the mechanical ventilation risk and improve oxygenation earlier, especially with early start of surfactant therapy

A pragmatic approach to the use of inotropes for the management of acute and advanced heart failure. an expert panel consensus

Inotropes aim at increasing cardiac output by enhancing cardiac contractility. They constitute the third pharmacological pillar in the treatment of patients with decompensated heart failure, the other two being diuretics and vasodilators. Three classes of parenterally administered inotropes are currently indicated for decompensated heart failure, (i) the beta adrenergic agonists, including dopamine and dobutamine and also the catecholamines epinephrine and norepinephrine, (ii) the phosphodiesterase III inhibitor milrinone and (iii) the calcium sensitizer levosimendan. These three families of drugs share some pharmacologic traits, but differ profoundly in many of their pleiotropic effects. Identifying the patients in need of inotropic support and selecting the proper inotrope in each case remain challenging. The present consensus, derived by a panel meeting of experts from 21 countries, aims at addressing this very issue in the setting of both acute and advanced heart failure

Limit cycles in uniform isochronous centers of discontinuous differential systems with four zones

We apply the averaging theory of first order for discontinuous differential systems to study the bifurcation of limit cycles from the periodic orbits of the uniform isochronous center of the differential systems ẋ = -y+x, y = x + xy, and ẋ = -y + xy, y = x + xy, when they are perturbed inside the class of all discontinuous quadratic and cubic polynomials differential systems with four zones separately by the axes of coordinates, respectively. Using averaging theory of first order the maximum number of limit cycles that we can obtain is twice the maximum number of limit cycles obtained in a previous work for discontinuous quadratic differential systems perturbing the same uniform isochronous quadratic center at origin perturbed with two zones separately by a straight line, and 5 more limit cycles than those achieved in a prior result for discontinuous cubic differential systems with the same uniform isochronous cubic center at the origin perturbed with two zones separately by a straight line. Comparing our results with those obtained perturbing the mentioned centers by the continuous quadratic and cubic differential systems we obtain 8 and 9 more limit cycles respectively
