У статті розглядається актуальна проблема українських реалій – психологічні особливості переживання стресу підлітками з окупованих територій у порівнянні з їх ровесниками, які проживають на території без бойових дій або  мають батьків – учасників АТО.  Представлено стислий огляд наукових досліджень щодо порушень емоційної сфери, фізіологічних, емоційних, поведінкових проявів стресу. Надані результати поглибленої психодіагностики самопочуття, настрою, активності, пізнавальної активності, мотивації навчання. Зроблена спроба визначення основних дій практичного психолога у роботі з дітьми, які переживають наслідки стресових, травматичних ситуацій

High-Altitude Configuration of Non-Terrestrial Telecommunication Network using Optical Wireless Technologies

Non-terrestrial communication technologies will become a key component for the development of future 6th generation (6G) networks. Potentials, implementation prospects, problems and solutions for non-terrestrial telecommunications remain open areas for future research. The article discusses the use of millimeter and optical wavelengths in various configurations of multilevel space communications using LEO satellites, stratospheric platforms and unmanned repeaters. The comparison of the capacity of the Shannon channel for various multi-level scenarios of the satellite communication line is carried out. The directions of research are analyzed to ensure the continuity of communication, adaptation to weather conditions, and achieving a throughput of up to 100 Gbit/s

Invasion of Parthenocissus quinquefolia (L.) Planch in the forest-steppe of Ukraine

Research needs of adaptation mechanisms of invasive alien species arises in connection with the naturalization of species of the genus Parthenocissus Planch in forest ecosystems of Ukraine. The results showed that P. quinquefolia has a wide range of values of edaphic and climatic factors. The populations of P. quinquefolia differ according to the degree of anthropogenic transformation of the ecotope, the ecological conditions formed, and the allocation of coenotics. The biomorphological characteristics of the species variability are shown on the gradient of anthropogenic transformation. Diagnostic parameters of P. quinquefolia under the conditions of anthropogenic transformation are the number of crotches of the tendrils and the length of the tendrils. The number of flowers per plant is characterized by the highest level of variation and belongs to the V class of variability. The smallest plasticity is characterized by the diameter of the stem. Vitality analysis indicated that cenopopulations of P. quinquefolia belong to the equilibria or prosperous population types, regardless of the intensity of the anthropogenic factor

Frobenius groups of automorphisms and their fixed points

Suppose that a finite group $G$ admits a Frobenius group of automorphisms $FH$ with kernel $F$ and complement $H$ such that the fixed-point subgroup of $F$ is trivial: $C_G(F)=1$. In this situation various properties of $G$ are shown to be close to the corresponding properties of $C_G(H)$. By using Clifford's theorem it is proved that the order $|G|$ is bounded in terms of $|H|$ and $|C_G(H)|$, the rank of $G$ is bounded in terms of $|H|$ and the rank of $C_G(H)$, and that $G$ is nilpotent if $C_G(H)$ is nilpotent. Lie ring methods are used for bounding the exponent and the nilpotency class of $G$ in the case of metacyclic $FH$. The exponent of $G$ is bounded in terms of $|FH|$ and the exponent of $C_G(H)$ by using Lazard's Lie algebra associated with the Jennings--Zassenhaus filtration and its connection with powerful subgroups. The nilpotency class of $G$ is bounded in terms of $|H|$ and the nilpotency class of $C_G(H)$ by considering Lie rings with a finite cyclic grading satisfying a certain `selective nilpotency' condition. The latter technique also yields similar results bounding the nilpotency class of Lie rings and algebras with a metacyclic Frobenius group of automorphisms, with corollaries for connected Lie groups and torsion-free locally nilpotent groups with such groups of automorphisms. Examples show that such nilpotency results are no longer true for non-metacyclic Frobenius groups of automorphisms.Comment: 31 page

Ressurgimento do sarampo no Brasil: análise da epidemia de 2019 no estado de São Paulo

OBJECTIVE To analyze the epidemiological profile of cases and the pattern of spatial diffusion of the largest measles epidemic in Brazil that occurred in the post-elimination period in the state of São Paulo. METHOD A cross-sectional study based on confirmed measles cases in 2019. Bivariate analysis was performed for socioeconomic, clinical, and epidemiological variables, according to prior vaccination and hospitalization, combined with an analysis of spatial diffusion of cases using the Inverse Distance Weighting (IDW) method. RESULTS Of the 15,598 confirmed cases, 2,039 were hospitalized and 17 progressed to death. The epidemic peak occurred in epidemiological week 33, after confirmation of the first case, in the epidemiological week 6. Most cases were male (52.1%), aged between 18 and 29 years (38.7%), identified as whites (70%). Young adults (39.7%) and children under five years (32.8%) were the most affected age groups. A higher proportion of previous vaccination was observed in whites as compared to Blacks, browns, yellows and indigenous people (p < 0.001), as well as in the most educated group compared to the other categories (p < 0.001). The risk of hospitalization was higher in children than in the older age group (RI = 2.19; 95%CI: 1.66–2.88), as well as in the unvaccinated than in the vaccinated (RI = 1.59; 95%CI: 1.45–1.75). The pattern of diffusion by contiguity combined with diffusion by relocation followed the urban hierarchy of the main cities’ regions of influence. CONCLUSION In addition to routine vaccination in children, the findings indicate the need for immunization campaigns for young adults. In addition, studies that seek to investigate the occurrence of clusters of vulnerable populations, prone to lower vaccination coverage, are essential to broaden the understanding of the dynamics of transmission and, thus, reorienting control strategies that ensure disease elimination.OBJETIVO Analisar o perfil epidemiológico dos casos e o padrão de difusão espacial da maior epidemia de sarampo do Brasil ocorrida no período pós-eliminação, no estado de São Paulo. MÉTODO Estudo transversal, baseado em casos confirmados de sarampo em 2019. Foi conduzida análise bivariada das variáveis socioeconômicas, clínicas e epidemiológicas, segundo vacinação prévia e ocorrência de hospitalização, combinada a uma análise de difusão espacial dos casos por meio da metodologia de interpolação pela ponderação do inverso da distância. RESULTADOS Dos 15.598 casos confirmados, 2.039 foram hospitalizados e 17 evoluíram para o óbito. O pico epidêmico ocorreu na semana epidemiológica 33, após a confirmação do primeiro caso, na semana epidemiológica 6. A maioria dos casos era homem (52,1%), com idade entre 18 e 29 anos (38,7%), identificados como brancos (70%). Adultos jovens (39,7%) e menores de cinco anos (32,8%) foram as faixas etárias mais acometidas. Observou-se maior proporção de vacinação prévia em brancos, quando comparados a pretos, pardos, amarelos e indígenas (p < 0,001), assim como no grupo mais escolarizado, quando comparado às demais categorias (p < 0,001). O risco de hospitalização foi maior em crianças, quando comparado à faixa etária mais idosa (RI = 2,19; IC95% 1,66–2,88), assim como entre não vacinados, quando comparado a vacinados (RI = 1,59; IC95% 1,45–1,75). O padrão de difusão por contiguidade combinado à difusão por realocação seguiu a hierarquia urbana das regiões de influência das principais cidades. CONCLUSÃO Além da vacinação de rotina em crianças, os achados indicam a necessidade de campanhas de imunização de adultos jovens. Adicionalmente, estudos que busquem investigar a ocorrência de clusters de populações vulneráveis, propensas a menor cobertura de vacinação, são essenciais para ampliar a compreensão sobre a dinâmica de transmissão da doença e, assim, reorientar estratégias de controle que garantam a eliminação da doença
