Молодежь современной Беларуси: базовые ценности, жизненные планы и поведенческие стратегии

The article considers the transformation of basic values, life plans and behavioral strategies of the youth in contemporary Belarus. The changes in basic values are directly connected with the youth's adaptation to the conditions of global instability. The new generation is sensitive to social injustice, violations of rights and freedoms, unwillingness to take into account their opinions on current issues of social development and the future. The self-perception of people regarding the possibility to realize basic values in the current social-economic conditions is an important factor of social stability. In both 1990 and 2018, family holds the first place among the basic values in Belarus; work takes the second place as a factor of decent life and family's success; the importance of friends and leisure remains the same over the decades, while the importance of politics and religion grows. International comparisons show that Belarus has the same hierarchy of values as European countries. The surveys prove a decrease in popularity of the traditional media among the youth and an increase in individualism, importance of personal self-realization in family and at work, and in reliance on one’s own forces. In the public space, the needs and expectations of people have changed - there is an increase in political radicalization and critical perception of the most important events, which affects the behavioral patterns of social-demographic groups. Education together with the family and new information technologies have a significant impact on values - there is an intragenerational gap, alienation from society and increasing informatization. The article is based on the results of the sociological surveys conducted in the framework of the European Values Study (EVS) (the results of 1990 and 2018 are compared)

Белорусское общество: от ценностей выживания к ценностям развития и самовыражения

The article considers new trends in the value system of the Belarusian society. Based on the data of the international sociological surveys conducted as waves of the European Values Study and World Values Study, the authors identify changes in the value orientations of the Belarusian society over the past thirty years. The authors use the methodological approach to identifying the system of value orientations that was developed by R. Inglehart and K. Welzel. The study of fundamental trends in the changing value world of the contemporary society is of practical importance for understanding internal factors of the current socialpolitical processes and for assessing prospects for the further sustainable development of socialpolitical institutions. The article aims at identifying the main directions in the transformation of the value orientations of the Belarusian society since the acquisition of state sovereignty. The authors conclude that the Belarusian society moves from the values of survival to the values of development and self-expression. In the project, the authors conducted an analysis of the demographic structure of the Belarusian society in terms of value priorities and found out that the demographic base of secular-individualistic and self-expression values consists of highly educated residents of large cities of younger (under 30) and middle (up to 49) age. Given the growth of the share of population with higher education and the second wave of urbanization (the outflow from small towns to large cities), we should expect an expansion of this demographic base and, accordingly, the further spread of these value orientations. In this situation, the education system acts as a source of the ongoing changes and develops the value matrix of the coming social reality

Spontaneous non-traumatic splenic artery aneurysm rupture: a case report and review of the literature.

The current case report is about spontaneous non-traumatic rupture of a splenic artery aneurysm (SAA) in a 53-year-old woman with no particular medical history. An emergent laparotomy with splenectomy was required, unfortunately without success as the patient died. SAA is the most common visceral artery aneurysm. Most of SAA remain asymptomatic and are discovered incidentally on imaging. The overall risk of rupture increases with the size of SAA, especially when above 2 cm. Initial presentation of SAA has been associated with acute rupture and hemodynamic instability leading to substantial perioperative morbidity and mortality

Investigation of the Kinetics of the Release of Main Gaseous Fission Products from Promising Fuel Samples of High-Temperature Gas-Cooled Reactors

This work is devoted to an experimental study of the kinetics of the release of the main gaseous fission products from promising fuel samples of high-temperature gas-cooled reactors on the basis of the conducted reactor ampoule tests in the IVV-2M reactor

MODELING THE BURNUP PROCESS OF NPN AND PUO2 FUEL COMPOSITIONS IN THE ADVANCED CONCEPTS OF A PULSED BATCH REACTOR IBR-3 AND IBR-4

Postmortem Cardiopulmonary Pathology in Patients with COVID-19 Infection: Single-Center Report of 12 Autopsies from Lausanne, Switzerland.

We report postmortem cardio-pulmonary findings including detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in formalin-fixed paraffin embedded tissue in 12 patients with COVID-19. The 5 women and 7 men (median age: 73 years; range 35-96) died 6-38 days after onset of symptoms (median: 14.5 days). Eight patients received mechanical ventilation. Ten patients showed diffuse alveolar damage (DAD), 7 as exudative and 3 as proliferative/organizing DAD. One case presented as acute fibrinous and organizing pneumonia. Seven patients (58%) had acute bronchopneumonia, 1/7 without associated DAD and 1/7 with aspergillosis and necrotic bronchitis. Microthrombi were present in 5 patients, only in exudative DAD. Reverse transcriptase quantitative PCR detected high virus amounts in 6 patients (50%) with exudative DAD and symptom-duration ≤14 days, supported by immunohistochemistry and in-situ RNA hybridization (RNAscope). The 6 patients with low viral copy levels were symptomatic for ≥15 days, comprising all cases with organizing DAD, the patient without DAD and one exudative DAD. We show the high prevalence of DAD as a reaction pattern in COVID-19, the high number of overlying acute bronchopneumonia, and high-level pulmonary virus detection limited to patients who died ≤2 weeks after onset of symptoms, correlating with exudative phase of DAD

Quantum Fourier transform, Heisenberg groups and quasiprobability distributions

This paper aims to explore the inherent connection among Heisenberg groups, quantum Fourier transform and (quasiprobability) distribution functions. Distribution functions for continuous and finite quantum systems are examined first as a semiclassical approach to quantum probability distribution. This leads to studying certain functionals of a pair of "conjugate" observables, connected via the quantum Fourier transform. The Heisenberg groups emerge naturally from this study and we take a rapid look at their representations. The quantum Fourier transform appears as the intertwining operator of two equivalent representation arising out of an automorphism of the group. Distribution functions correspond to certain distinguished sets in the group algebra. The marginal properties of a particular class of distribution functions (Wigner distributions) arise from a class of automorphisms of the group algebra of the Heisenberg group. We then study the reconstruction of Wigner function from the marginal distributions via inverse Radon transform giving explicit formulas. We consider applications of our approach to quantum information processing and quantum process tomography.Comment: 39 page

Wide-band negative permeability of nonlinear metamaterials

We propose a novel way to achieve an exceptionally wide frequency range where metamaterial possesses negative effective permeability. This can be achieved by employing a nonlinear response of metamaterials. We demonstrate that, with an appropriate design, a frequency band exceeding 100% is available for a range of signal amplitudes. Our proposal provides a significant improvement over the linear approach, opening a road towards broadband negative refraction and its applications

A nilpotent IP polynomial multiple recurrence theorem

We generalize the IP-polynomial Szemer\'edi theorem due to Bergelson and McCutcheon and the nilpotent Szemer\'edi theorem due to Leibman. Important tools in our proof include a generalization of Leibman's result that polynomial mappings into a nilpotent group form a group and a multiparameter version of the nilpotent Hales-Jewett theorem due to Bergelson and Leibman.Comment: v4: switch to TeXlive 2016 and biblate
