    This paper examines the role of facial apparent movements in the assessment of basic emotional expressions in favorable and adverse conditions of perception. A previous study has shown that movement could not improve the accuracy of the assessment of emotions in the presence of the detailed information about the configuration of the face. The present investigation aimed at searching conditions inwhich dynamics provided better assessment of facial expressions. In the psychophysical experiment the modality of expression (6 basic emotions and neutral face), the context, the time of exposure of the face (50, 100, or 200 ms), and the degree of its defocusing (clear or blurry images) varied. The stimulus situation type determinedthe content of the context: the stroboscopic exposure of expressions against the background of a neutral face or their direct and reverse visual masking by a randomized pattern. The use of a Gaussian filter with pixel values of 20, 40, or 60 provided defocusing. The authors analyzed the data using the method of mixedeffects logistic regression; the frequencies of correct answers in the experimental conditions were compared using linear contrasts. The findings of the study revealed that during stroboscopic exposure the apparent movement ensured the preservation of the accuracy of recognition of basic emotionseven in the least favorable conditions of perception (at minimum exposure time and maximum image defocusing). For clear or slightly defocused images the accuracy of assessments when masking and the stroboscopic change of the expression coincided.Masking led to a significant reduction in the accuracy of the assessments of emotions  when deteriorating the conditions of perception. The impact of masking was higher when assessing low-attractive emotions (disgust, fear, sadness, and anger); highattractiveemotions (joy, surprise, and calm state) were assessed most adequatelyin all stimulus situations. The obtained effect of stroboscopic sensitization indicated the similarity of the impact of a real and apparent movement on the assessment of emotional states.Π˜Π·ΡƒΡ‡Π°Π»Π°ΡΡŒ Ρ€ΠΎΠ»ΡŒ каТущСгося двиТСния Π»ΠΈΡ†Π° Π² ΠΎΡ†Π΅Π½ΠΊΠ΅ Π±Π°Π·ΠΎΠ²Ρ‹Ρ… ΡΠΌΠΎΡ†ΠΈΠΎΠ½Π°Π»ΡŒΠ½Ρ‹Ρ… экспрСссий Π² благоприятных ΠΈ Π·Π°Ρ‚Ρ€ΡƒΠ΄Π½Π΅Π½Π½Ρ‹Ρ… условиях восприятия.

    Computer Algebra in JULIA

    No full text
    Recently, the place of the main programming language for scientific and engineering computations has been little by little taken by Julia. Some users want to work completely within the Julia ecosystem like they work within the Python ecosystem. There are libraries for Julia that cover the majority of scientific and engineering computations demands. The aim of this paper is to combine the usage of Julia framework for numerical computations and for symbolic computations in mathematical modeling problems. The main functional domains determining various variants of the application of computer algebra systems are described. In each of these domains, generic representatives of computer algebra systems in Julia are distinguished. The conclusion is that it is possible (and even convenient) to use computer algebra systems within the Julia ecosystem

    This paper considers three types of tensor computations. On their basis, we attempt to formulate criteria that must be satisfied by a computer algebra system dealing with tensors. We briefly overview the current state of tensor computations in different computer algebra systems. The tensor computations are illustrated with appropriate examples implemented in specific systems: Cadabra and Maxima. Β© 2013 Pleiades Publishing, Ltd

    CLINICAL AND IMMUNOLOGICAL EFFICACY OF INOSINE PRANOBEX FOR ACUTE RESPIRATORY INFECTIONS IN CHILDREN WITH ATOPIC ASTHMA

    No full text
    The prevalence rate of atopic asthma in children remains high. One of the reasons for lack of control over asthma symptoms is repeated infection. The article describes results from the study of immunomodulating medication inosine pranobex used in treatment of acute respiratory infections in children with atopic asthma. The results obtained prove the efficacy and safety of this medication. The use of this immunomodifier with antiviral activity during the period of acute respiratory infection in children with atopic asthma contributes to shortening of intoxication and catarrhal signs duration, elimination of viral agents. Key words: asthma, acute respiratory infections, immunomodifiers, inosine pranobex, children. (Pediatric Pharmacology. – 2010; 7(3):98-105
