Приведен анализ специфических особенностей проявления отклоняющегося поведения у подростков с детским церебральным параличом, выявлен в процессе эмпирического исследования в сравнении с подростками с нормальным психическим развитием и связанных со структурой дефекта. Так, у подростков с детским церебральным параличом выявлен высокий уровень межличностной и социальной тревожности, высокая демонстративность, аффективность, трудности в формировании межличностных отношений со сверстниками и взрослыми, приводящие к формированию у них чувства одиночества и покинутости, сниженного настроения, а также отсутствие позитивных перспектив в будущем, агрессивность и склонность к аутодеструктивному поведению, которые могут послужить факторами возникновения суицидального поведения. Выявленные особенности подростков с детским церебральным параличом указывают на необходимость разработки и реализации комплексной программы профилактики у них суицидального поведения.The article treats the issue of suicidal behavior in adolescents with cerebral palsy as compared with their physically able peers. It describes some factors inducing suicidal ideation and suicidal behavior in physically able teenagers and in adolescents with physical disabilities. The article underlines the importance of the prevention of suicidal thoughts and acts among adolescents with cerebral palsy. It empirically assesses and analyzes the peculiarities of suicidal behavior in adolescents with cerebral palsy as compared with suicidal ideation in physically able adolescents. The research shows that teenagers with cerebral palsy show higher levels of interpersonal and social anxiety, ostentation and excessive affectivity, experience communication difficulties when interacting with their peers and adults and, therefore, feel lonely, depressed and neglected, see nothing positive in their future, show aggression and are prone to self-destructive behavior, which can easily trigger suicidal thoughts and acts. The analysis of psychological peculiarities of teenagers with cerebral palsy highlights the necessity to develop and implement a teenager suicide prevention program.

Introduction: Tetanus has a worldwide distribution and high lethality. The goal of this study was to characterize the tetanus cases confirmed in Pernambuco and identify factors associated with death in these patients.
Methods: Cross-sectional, with internal comparison groups. For data analysis we used the chi-square test and Pearson estimated the odds ratios and their respective confidence intervals at 95%. Multivariate analysis was applied to multiple logistic regression
Results: The incidence of tetanus ranged between 0.65 and 2.79 cases per 100,000 inhabitants with higher involvement of adults, male and city population. Only 13.8% had received the vaccine and 23.4% received it as prophylaxis. The average mortality rate was 20.4%. In multivariate analysis, presented neck stiffness as a symptom (p = 0.029), which was associated with increased mortality.
Conclusion: There is a need for greater investment in the prevention of the disease, both in immunization coverage and in the application of prophylaxis. Despite the hospitalization guarantee with proper care, there was an increase in tetanus mortality, suggesting that more specific studies should be conducted to investigate what may have influenced this change. Special attention should be offered to cases that presented neck stiffness as a symptom, because these groups have a higher chance of progressing to death.
A Fast, Two-dimensional Gaussian Process Method Based on Celerite: Applications to Transiting Exoplanet Discovery and Characterization
Authors: Gordon Tyler A. , Agol Eric , Foreman-Mackey Daniel 
Published: November 2020

Abstract
Gaussian processes (GPs) are commonly used as a model of stochastic variability in astrophysical time series. In particular, GPs are frequently employed to account for correlated stellar variability in planetary transit light curves. The efficient application of GPs to light curves containing thousands to tens of thousands of data points has been made possible by recent advances in GP methods, including the celerite method. Here we present an extension of the celerite method to two input dimensions where, typically, the second dimension is small. This method scales linearly with the total number of data points when the noise in each large dimension is proportional to the same celerite kernel and only the amplitude of the correlated noise varies in the second dimension. We demonstrate the application of this method to the problem of measuring precise transit parameters from multiwavelength light curves and show that it has the potential to improve transit parameters measurements by orders of magnitude. Applications of this method include transit spectroscopy and exomoon detection, as well a broader set of astronomical problems.
High-level Ab Initio Studies of the Spectroscopic Properties of Triatomic [Al, S, O]x (x = 0, +1) and Its Potential for Detection in Space
Authors: Esposito Vincent J. , Trabelsi Tarek , Francisco Joseph S. 
Published: November 2020

Abstract
Highly reliable molecular properties have been computed for the [Al, S, O]
x
(x = 0, +1) molecular system. Spectroscopic parameters are predicted from analysis of each isomer’s 3D potential energy surface calculated using the explicitly correlated multireference configuration interaction method, including the Davidson correction (MRCI-F12+Q). These parameters provide an accurate prediction of spectroscopic data that can be used in laboratory and observational studies of these molecules. Linear-SAlO is expected to have a large permanent dipole moment suitable for detection in the circumstellar envelopes of large, evolved, oxygen-rich stars such as VY Canis Majoris, IK Tauri, and R Doradus. Frequencies are provided for rotational transitions originating from the most highly populated rotational state based on a Boltzmann distribution. Additionally, both linear isomers exhibit a flat potential along the bending angle and are predicted to have very low bending mode frequencies (<200 cm−1), complicating the spectra of these molecules.
A Model for the Fast Blue Optical Transient AT2018cow: Circumstellar Interaction of a Pulsational Pair-instability Supernova

Published: November 2020

Abstract
The fast blue optical transient (FBOT) ATLAS18qqn (AT2018cow) has a light curve as bright as that of superluminous supernovae (SLSNe) but rises and falls much faster. We model this light curve by circumstellar interaction of a pulsational pair-instability (PPI) supernova (SN) model based on our PPISN models studied in previous work. We focus on the 42 M
⊙ He star (core of a 80 M
⊙ star) which has circumstellar matter (CSM) of mass 0.50 M
⊙. With the parameterized mass cut and the kinetic energy of explosion E, we perform hydrodynamical calculations of nucleosynthesis and optical light curves of PPISN models. The optical light curve of the first ∼20 days of AT2018cow is well reproduced by the shock heating of CSM for the 42 M
⊙ He star with E = 5 × 1051 erg. After day 20, the light curve is reproduced by the radioactive decay of 0.6

Co, which is a decay product of 56Ni in the explosion. We also examine how the light-curve shape depends on the various model parameters, such as CSM structure and composition. We also discuss (1) other possible energy sources and their constraints, (2) the origin of the observed high-energy radiation, and (3) how our result depends on the radiative transfer codes. Based on our successful model for AT2018cow and the model for SLSN with CSM mass as large as

, we propose the working hypothesis that PPISN produces SLSNe if the CSM is massive enough and FBOTs if CSM is less than ∼1 M

Abstract
On mission sol 783 (at Martian solar longitude (L

S
) of 217°), Mars Science Laboratory's MastCam instrument imaged a faint glow, extending upwards from the horizon (Figure 1(a)). The images were acquired from 18:58 to 19:01 LTST, nearly an hour after sunset occurred at 18:05 LTST, providing an opportunity to examine illumination in the Martian sky around sunset. The radiance of the observed glow is small when compared to daytime sky brightness values, with an average value between 20 and 35 μW m−2 Sr−1, and appears brightest in the blue filter (the average B/R ratio is 1.25). The total flux at the time of the measurement was calculated to be 4.2 × 10−4 W m−2, nearly three orders of magnitude dimmer than what would be expected for an Earth-like Atmosphere. An observer on the surface of Mars would thus find twilight becoming deeper much more rapidly than on the Earth.
Langue poétique et formes dialectales dans les inscriptions versifiées grecques : le cas de la Cyrénaïque
Authors: Dobias-Lalou Catherine 
Published: November 2020

Le corpus des inscriptions métriques de Cyrénaïque, constitué de 55 entrées, comprend des textes de types variés et s’étale du vi e siècle av. J.-C. au vi e siècle apr. J.-C., avec un pic très net au ii e siècle apr. J.-C. Comme le dialecte reste encore vivace pendant toute la période hellénistique, on peut étendre l’enquête jusqu’au début de notre ère. Après un catalogue systématique des traits dialectaux retenus ou évités, que ceux-ci relèvent de la phonétique, de la morphologie ou du vocabulaire, la prise en compte des conditions d’énonciation permet d’affiner l’appréciation de la bigarrure linguistique à la lumière d’une étude détaillée de quelques textes représentatifs.
Un nouvel outil numérique : StopCovid
