Telang flower (Clitoria ternatea L.) contains anthocyanins that are efficacious as natural antioxidants. Face mist with synthetic materials, such as tertiary-butyl hydroquinone (TBHQ), has side effects that are carcinogenic and can cause tumors if used for a long time. Currently, many studies haveeinvestigated the conventional biotechnology product kombucha,, which is a drink made from tea fermented by bacteria and yeast (Scoby/Symbiotic Colony (Culture) Bacteria &Yeast,), as the initial culture of the tea produces an aroma or sour taste. Kombucha has various anti-inflammatory, antibacterial, and antioxidant activities of certain strains, which are expected to provide good antioxidant activity when combined with the natural ingredients of Telang flowers. In this study, telang flower simplicia was fermented for 6 days until telang flower kombucha tea was obtained, and face mist preparations in three concentrations (5%, 7,5%, and 10%) were prepared to determine the antioxidant activity using the DPPH method measured by UV-Vis spectrophotometry by looking at the % inhibition and IC50 values. Based on the results of the evaluation with the parameters of organoleptic testing, pH, homogeneity, spray dispersion, specific weight, viscosity, and drying time met the requirements. The result of the antioxidant activity test of vitamin C of 4,36 ppm, kombucha of telang flower of 14,19 ppm, and face mist of kombucha of telang flower with concentrations of 5%, 7,5% and 10% produced IC50 values of 21,19 ppm, 19,62 ppm, and 17,52 ppm and were included in the very strong category.

ФРАЗЕОЛОГИЗМЫ С КОМПОНЕНТОМ КОЛОКОЛ В РУССКОЙ И КИТАЙСКОЙ ЛИНГВОКУЛЬТУРАХ
Authors: Николаева Е.К. , Бай Г. 
Published: December 2024

В статье рассматриваются устойчивые выражения русского и китайского языков, в которых содержится лексема колокол – один из частотных компонентов во фразеологии с «музыкальными мотивами», обладающий большим лингвокультурологическим потенциалом. Анализ фразеологического материала двух языков позволил показать как общее, так и различное, выявить национальную специфику фразеологизмов с образом колокола, что является целью данной статьи. Актуальность работы обусловлена перспективностью исследований фразеологии в целом и отсутствием сравнительного описания рассматриваемой группы фразеологических единиц русского и китайского языков. Использование методов лингвокультурологического и сопоставительного анализов позволил авторам прийти к выводам, что одно и то же слово может порождать различные ассоциации, иметь специфический набор коннотативных признаков, что обусловлено особенностями в культуре и менталитете наций. Наибольшее число совпадений обнаружено в группе фразеологизмов, связанных с речевой деятельностью, где колоколможет характеризовать как акустико-физиологическую, так и содержательную сторону речи. В целом в китайском языке образная составляющая семантики фразеологизмов с анализируемым компонентом шире, чем в русском – лексема может обозначать богатство, настоящее искусство, любовь, ум и старость.
The article examines phraseological units in the Russian and Chinese languages, which contain the word bell – one of the frequent components in phraseology with “musical motifs”, which has great linguistic and cultural potential. The comparison of the phraseological material of the two languages made it possible to show both the common and the different in the two linguistic cultures, to identify the national specifics of phraseological units with the bellcomponent, which is the purpose of this article. The relevance of the work is due to the prospects of linguistic and cultural studies of phraseology in general and the lack of a comparative description of this group of phraseological units in two linguistic studies. The use of methods of linguistic and cultural analysis and comparative analysis allowed the authors to conclude that the same reality can generate different associations between Russians and Chinese, have a different set of associative features due to the difference in culture and mentality of the nations. The largest number of coincidences was found in the group of phraseological units associated with speech activity, where the bell can characterize both the acoustic-physiological and the meaningful side of speech. In general, in Chinese phraseology, the figurative component of the semantics of phraseological units with the bellcomponent is wider than in Russian: the lexeme can act as a symbol of wealth, real art, love, intelligence and old age.

В статье рассмотрены особенности электронного обучения как одной из ведущих форм современного образования, в частности, дисциплинам учебного плана направления «Филология». Представлены материалы по ряду предметных областей филологического цикла и рекомендации по организации цифрового обучения для иностранных и российских студентов. После пандемии COVID-19 многие вузы продолжают широко использовать известные учебные платформы, а также создают собственные электронные образовательные системы. В статье отражен опыт создания онлайн-курсов по дисциплинам филологического цикла для иностранных студентов-филологов, обучающихся по программам бакалавриата и магистратуры. Отмечается, что сочетание традиционной текстоцентрической методики преподавания русского языка как иностранного и технологий электронного обучения позволяет создать цифровые ресурсы, в высокой мере соответствующие дидактическим принципам доступности, прочности, наглядности, связи теории с практикой, систематичности и последовательности, самостоятельности, активности и сознательности учащихся, а потому, как показала практика, востребованные не только иностранными, но и российскими студентами. Тем самым умелое использование образовательных возможностей информационно-коммуникационных технологий, современных гаджетов, мультимедийных систем, педагогических инноваций позволяет повысить гибкость, конкурентоспособность российского образования, в частности, филологического.
The article considers the features of e-learning as one of the leading forms of modern education, in particular, of philological sciences training. The author presents educational materials on a number of the philological sciences and recommendations on the foreign and Russian Philology students e-learning. After the COVID-19 pandemic, many universities use well-known online educational platforms and create their own electronic educational systems which host e-learning courses. The article presents the experience of creating e-courses in the Philological sciences for foreign students of philology studying undergraduate and graduate programs. It is noted that the combination of traditional text-centric methods of Russian as a Foreign Language training and e-learning technologies makes it possible to create specialized online-courses in Philology that are highly consistent with the didactic principle of thorough acquisition of knowledge, skills and abilities, the principle of connecting theory with practice, the principle of systematization and continuity, etc. As practice has shown, not only foreign, but also Russian students demand these online-courses. It seems that the skillful use of the didactic capabilities of information and telecommunication networks and technologies, modern gadgets, multimedia systems, and pedagogical innovations makes it possible to increase the accessibility, flexibility, and competitiveness of Russian philological education.

В настоящее время в стране особое внимание уделяется обучению русскому языку как неродному детей-инофонов. В связи с этим актуален вопрос изучения языка в полиэтнических регионах, в частности, в ХМАО-Югра. Важно дать школьникам не только знания и умения, направленные на развитие основных речевых видов деятельности, необходимых для повседневной коммуникации, но и обратиться к страноведческим, краеведческим темам, с помощью которых возможно достижение социокультурной адаптации обучающихся, погружение их в определенную культурную среду. В статье рассматривается возможность использования текстов краеведческой тематики в учебныхпособиях по русскому языку для детей-инофонов. Делается вывод о том, что работа с региональными текстами поможет данной категории обучающихся преодолеть процесс языковой и социокультурной адаптации в обществе.
Recently, in Russia as a whole and in some regions in particular, more and more attention has been paid to the methods of teaching Russian to non-native-speaker children. This methodological problem is also relevant in such a multi-ethnic region as Khanty-Mansi Autonomous Okrug -Yugra. It is important to give schoolchildren not only knowledge and skills aimed at developing the basic speech activities necessary for everyday communication, but also to address regional studies and local history topics, with the help of which it is possible to achieve socio-cultural adaptation of students, immersing them in a certain cultural environment. The article considers the possibility of using local history texts in Russian language teaching aids for non-native-speaker children. It is concluded that working with regional texts will help this category of students to more successfully go through the process of linguistic and socio-cultural adaptation in a new community.

Authors: Мурашкин Е.В. , Стадник Н.Э. 
Published: December 2024

В настоящей работе рассматривается мультивесовая теория слабых разрывов температурного инкремента, трансляционных и спинорных перемещений в полуизотропной термоупругой микрополярной среде. Предлагаемая к рассмотрению математическая теория существенным образом опирается на достижения современного псевдотензорного исчисления. Приводятся определения мультивесовых псевдотензорных элементов площади и объема. Выводится общая мультивесовая форма псевдотензорного соотношения на волновой поверхности, распространяющейся в полуизотропной термоупругой микрополярной среде. Исследуются слабые разрывы решений связанной системы псевдовекторных дифференциальных уравнений в частных производных полуизотропной микрополярной термоупругости. С этой целью геометрические и кинематические условия Адамара–Томаса обобщены на псевдотензорный случай с учетом псевдотензорной геометрии распространяющейся поверхности слабых разрывов. Найдены скорости распространения волновых поверхностей трансляционных и спинорных перемещений. Проведена классификация слабых разрывов температуры, трансляционных и спинорных перемещений и исследованы их пространственные поляризации. Установлены условия атермичности, распространяющихся волновых поверхностей слабых разрывов.
In this paper, we consider a multiweight theory of weak discontinuities of the temperature increment, translational and spinor displacements in a semi-isotropic thermoelastic micropolar medium. The mathematical theory proposed for consideration is substantially based on the achievements of modern pseudotensor calculus. Definitions of multiweight pseudotensor elements of area and volume are revisited. A general multiweight form of a pseudotensor equation on a wave surface propagating in a semi-isotropic thermoelastic micropolar medium is derived. Weak discontinuities of solutions of the coupled system of pseudovector partial differential equations of semi-isotropic micropolar thermoelasticity are studied. For this aim the geometric and kinematic Hadamard–Thomas conditions are generalized to the pseudotensor case taking account of the pseudotensor geometry of the propagating surface of weak discontinuities. The propagation velocities of wave surfaces of translational and spinor displacements are found. A classification of weak discontinuities of temperature, translational and spinor displacements is carried out and their spatial polarizations are studied. The conditions of athermality of propagating wave surfaces of weak discontinuities are established.

Published: December 2024

Работа посвящена проблемам, связанным с распространением плоских гармонических связанных волн температурного инкремента, трансляционных и спинорных перемещений в ультрагемитропном микрополярном термоупругом теле. Приводится замкнутая система дифференциальных уравнений в частных производных второго порядка относительно температурного инкремента и перемещений (трансляционных и спинорных). Найдены и проанализированы характеристические уравнения для волновых чисел плоских гармонических связанных термоупругих волн. Получены алгебраические выражения для корней характеристических уравнений и отделены нормальные волновые числа с положительной действительной частью. Для продольной волны комплексные амплитуды температурного инкремента, трансляционных и спинорных перемещений оказываются связанными, в отличие от атермической по своей природе поперечной волны.
The study is devoted to problems associated with propagation of plane harmonic coupled waves of temperature increment, translational and spinor displacements in an ultrahemitropic micropolar thermoelastic solid. A closed system of differential equations in partial derivatives of the second order with respect to the temperature increment and displacements (translational and spinor) is revisited. Characteristic equations for wavenumbers of plane harmonic coupled thermoelastic waves are found and analyzed. Algebraic expressions for the roots of the characteristic equations are obtained and normal wavenumbers with a positive real part are separated. For a longitudinal wave, complex amplitudes of the temperature increment, translational and spinor displacements are coupled, in contrast to a transverse wave, which is athermal in nature.

Tazarotene-induced gene 1 (TIG1) is involved in modulating the α-tubulin modification and effectively inhibiting tumor growth. In this bioinformatics study, we aim to propose novel therapeutic targets in breast cancer by utilizing differentially expressed genes (DEGs) of TIG1 in inflammatory breast cancer (IBC) and examining their correlation with the molecular and immune subtypes. Using the GEO2R tool, we analyzed DEGs in the GSE30543 dataset, specifically comparing suppressed TIG1 groups with control samples from SUM149 cells. Functional annotation analysis of DEGs were explored using SRplot with data from STRING (|log2(FC)| >2 and p
Open Cluster Dynamics under the Influence of Outflow–Ambient Interactions
Authors: Liu Muxin , Wang Lile , Fu Xiaoting , Ho Luis C. 
Published: December 2024

Abstract
Stars with outflows impinging on ambient gas experience accelerations due to the gravitational feedback from the interaction morphology between the outflow and the ambient gas. Such “negative dynamical friction” (NDF), in contrast to the conventional “dynamical friction” (DF), is studied for its impact on the dynamics of open clusters (OCs) immersed in a uniform ambient gas. We modify the N-body integration code REBOUND with both NDF and DF implemented according to the outflow conditions of each star in a consistently constructed OC. The evolution of stars is also involved in determining the gas–star interactions throughout their stellar lives. Compared to DF-only and gas-free models with identical initial conditions, the NDF-affected cluster is puffier and evaporates faster, as indicated by various diagnostics, including lower velocity dispersions and larger half-mass and half-light radii. Neutron stars with fast winds are expelled from the cluster due to their intensive NDF effect, even without the “kicks” by asymmetric supernovae. Exploration of parameter space confirms that the NDF effect is generally enhanced with higher ambient gas densities, in qualitative agreement with the expression of acceleration. Outflow–ambient interactions should be considered for the proper interpretation of the stellar dynamics evolution in clusters.
Milky Way Dark Matter Distribution or MOND Test from Vertical Stellar Kinematics with Gaia DR3
Authors: López-Corredoira Martín 
Published: December 2024

Abstract
Vertical stellar kinematics+density can be used to trace the dark matter distribution (or the equivalent phantom mass in a Modified Newtonian Dynamics (MOND) scenario) through the Jeans equations. In this paper, we want to improve this type of analysis by making use of the recent data of the 6D information from the Gaia DR3 survey in the anticenter and the Galactic poles to obtain the dynamical mass distribution near plane regions, including extended kinematics over a wide region of 8 kpc < R < 22 kpc, ∣z∣ < 3 kpc. Our conclusions are as follows: (i) the model of the spherical dark matter halos and the MOND model are compatible with the data; (ii) the model of the disky matter (with density proportional to the gas density) is excluded; (iii) the total lack of dark matter (there is only visible matter) within Newtonian gravity is compatible with the data; for instance, at solar Galactocentric radius, we obtained Σ = 39 ± 18 M
⊙ pc−2 for z = 1.05 kpc, compatible with the expected value for visible matter alone of 44 M
⊙ pc−2, thus allowing zero dark matter. Similarly, for R > R
⊙, z = 1.05 kpc, Σ = 28.7 ± 9.6, 23.0 ± 5.7, 16.9 ± 5.8, and 11.4 ± 6.6 M
⊙ pc−2, respectively, for R = 10, 13, 16, and 19 kpc, compatible with visible matter alone. Larger error bars in comparison with previous works are not due to worse data or a more awkward technique but to a stricter modeling of the stellar distribution.
Detecting Dark Objects with Plasma Microlensing by Their Gravitational Wakes
Authors: Delos M. Sten 
Published: December 2024

Abstract
A moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could complement gravitational microlensing in the search for invisible massive objects, such as stellar remnants or compact dark matter. This work explores the spatial structure of the plasma lens associated with a gravitational wake. Far away from the moving mass, the characteristic lensing signal is the steady demagnification or magnification of a radio source as the wake passes in front of it at the speed of sound. Sources can be plasma-lensed at a much greater angular distance than they could be gravitationally lensed to the same degree by the same object. However, only the wakes of objects greatly exceeding stellar mass are expected to dominate over the random turbulence in the interstellar medium.

Abstract
The Gemini Planet Imager (GPI), an extreme adaptive optics instrument on Gemini South, has been pivotal in the advancement of the debris-disk field. Over the past decade, GPI has observed tens of debris disks at near-infrared wavelengths in both polarized and total intensity as a part of several direct-imaging surveys. Here we discuss the uniform reductions of the J-, H- and K1-band GPI observations, specifically in polarized intensity. This includes 24 debris-disk observations in the H band, 10 debris-disks observations in the J band and 11 disk observations in the K1 band. Additionally, all three reduced data sets have been archived on the digital platform, CANFAR, so that they are available for public use. The purpose of this work is to provide the necessary steps for one to carry out their own data reductions if desired, as well as to create a space where these uniformly reduced data are easily accessible for future analysis and research.
