Geodesia aplicada al monitoreo de desplazamientos de una ladera inestable y la influencia de la precipitación, durante el período 2008-2011, Teziutlán, Puebla.
Authors: Gómez Vázquez Ángel , Mendoza Rosas Ana Teresa
Published: October 2021

En octubre de 1999 ocurrió un deslizamiento en la colonia La Aurora de Teziutlán Puebla que provocó el deceso de 130 personas. Durante el periodo de 2008-2011, en esa ladera se construyó una red geodésica para detectar sus desplazamientos, la cual está constituida por 10 puntos sobre la misma y dos estaciones remotas de control, en este lapso de tiempo, efectuamos 11 campañas de mediciones de distancia con estación total. Detectamos desplazamientos negativos de entre -5 y -19mm en algunos puntos cercanos a la corona del deslizamiento de 1999, en el resto de puntos los cambios son muy pequeños. Las velocidades de desplazamientos son menores a 7.3mm por año, por lo que de acuerdo con la clasificación de Cruden y Varnes (1996) estaría situado en el nivel 1, como extremadamente lento. Calculamos los coeficientes de correlación entre los desplazamientos y variables meteorológicas, obtenidas de una estación de la CONAGUA (Comisión Nacional del Agua) cercana a la zona del deslizamiento, no mostrando correlaciones significativas.

Published: October 2021

Women in male domination and at the same time defends men with the dominance they have. This shows that there is an ambiguous attitude of a woman in responding to the discourse of male domination, injustice in the role of women and affirming women's resistance to male domination. From this, the main problem is the subject's response in dealing with the discourse of male domination through women's resistance strategies through participation in society. The concept or theory and research method used is hegemony. The results obtained are the idea of equality in education being used as a resistance strategy in the discourse of male domination and at the same time strengthening women's resistance to male domination. In addition, the strategy also developed the idea of women's strength based on educational equality, namely through access to higher education

Titanate Nanotubes (TNT) were synthesized by aging commercial titanium dioxide (TiO2 - Degussa P25) with an alkali (KOH) solution at different time intervals. The prepared materials were investigated for their surface composition and textural behaviour by X-ray powder diffraction (XRD), Raman spectroscopy, Gas (N2 and CO2) adsorption measurements, and Transmission electron microscopy (TEM). The X-ray diffraction spectra revealed the decrease in the crystalline nature of the materials decreased by exposing them for a longer duration in the base solution. Raman spectra results showed that ageing time affected the structural properties. The specific surface area and the pore size of the newly synthesised materials were affected by the ageing process. The TEM images showed the influence of ageing during the formation of titanate nanotubes. HRTEM revealed that Pd particle sizes of <1 nm was present inside the tubes.

The concept of Natural Language Processing that deals with problems of identifying the sentiment from the voice or text of a speaker or writer and then use that analysis further for making predictions, market survey, customer service, product satisfaction, precision targeting etc. is called Sentiment analysis. From one viewpoint, it is an abstract evaluation of something dependent on close to home observational experience. It Is mostly established in target realities and incompletely governed by feelings. Then again, a sentiment can be deciphered as a kind of measurement in the information in regards to a specific subject. It is a lot of markers that mix present a point of view, i.e., perspective for the specific issue. So as to enhance the accuracy of sentiment analysis/classification, it is imperative to appropriately recognize the semantic connections between the various words and phrases that are describing the subject or aspect. This can be done by applying semantic analysis with a syntactic parser and supposition vocabulary. This research will discuss different sets of approaches for application or domain specific problems and then compare them to obtain the best possible approaches to the problem of sentiment analysis.

DC Motor is an essential element for many applications in the field of automation, robotics, and many others. They are important for many engineers to understand its behaviours and characteristics. However, controlling any system is still a challenge because of their abnormal behavior. In this paper, we are applying techniques to understand the behavior of servo system. Several groups of researchers conducted experiments based on a standard first-order model of a DC Motor using first principles modeling to derive the parameters. However, not much highlighting is identified on how well these models match up the actual data. In this paper, a deeper understanding has been taken place to gain some familiarity in testing and measurements by exploring a special arrangement in a laboratory called Quanser QUBE-Servo. In addition to this, signals monitoring on the live-mode has the advantage of gaining conceptual knowledge in the experimental test, analysis, and verification of the system. On the other hand, solving differential equations numerically using powerful software such as LabVIEW which endorses the comprehension of the system operation. In general, this report discusses a simple technique to study the DC motor transient response, read the angular position of the encoder by interface data acquisition device used with LabVIEW software.

G-Coat Plus is a nano-filled, self-adhesive light cured protective coating that strengthens, protects and enhances glass ionomer restorations. The effect of G- Coat plus on different GICs have not been studied comprehensively. Hence the study was conducted to compare the effect of resin coating on surface hardness and Shear punch strength of newer modified GIC.Materials and methods: 120 samples of three GICs i.e. Fuji IX Extra, Fuji IX Fast, Fuji II LC were prepared using specialized metal moulds. Specimens of Fuji II LC were light cured for 20 seconds. Coated and uncoated samples were tested for surface hardness and 30 samples were tested for shear punch strength. P < 0.05 was considered as significant. Results: Shear Punch Strength after G-Coat plus coating was significantly higher for Fuji IX Extra followed by Fuji II LC. Surface Hardness after G- Coat plus coating was significantly higher for Fuji IX Extra followed by Fuji IX Fast and Fuji II LC.Conclusion: Surface coating by a resin agent significantly increases the surface hardness and shear strength of the GIC. Considering the above stated findings, they can be incorporated into daily clinical practice to enhance the strength and longevity of GIC.

The search for new, fast and non-invasive methods of diagnosing diseases of both the oral cavity and general diseases of various etiologies and their introduction into practical health care is still a priority in the field of medicine. Among the known methods of analysis of biological fluids, a special place is occupied by the study of saliva. Oral fluid analysis has a high potential in screening for various diseases, since it contains a wide range of organic and inorganic compounds. A significant number of works have been devoted to the study of the quantitative and qualitative composition of the oral fluid, as well as to the study of saliva biomarkers, however, the study of the saliva proteome is at the stage of data accumulation. The lack of standardization in the collection of samples and methods of analysis, as well as poorly studied physiological and biochemical parameters of the oral fluid, hinders the introduction of advances in the study of the saliva proteome into diagnostic practice. The solution of these problems will allow the oral fluid to be used as a biological environment for both detecting diseases and predicting their course.

Deep margin elevation (DME) is a nonsurgical, alternative technique of dental crown lengthening. Portion of direct restoration placed only at the deep apical part of the cavity to elevate the margin to a more coronal and more adequate position for final cementation of indirect restoration.Materials and methods.In this systematic review, we were looking for in vitro studies in which deep margin elevation (DME) technique were used. The electronic databases PubMed and EMBASE were used for the search. The search began on July 29, 2021 and ended on August 10, 2021. We have analyzed the materials and methods of each research and entered them in the appropriate tables to give a clearer assessment of the obtained results.Results.Analysis of marginal quality showed the best results when indirect restorations luted to dentin directly and with DME technique with three consecutive layers of resin composite. In groups without DME there were fewer microleakage. DME did not statistically significantly influence the fracture strength.Conclusions.We conducted a systematic review that included 12 in vitro studies. Even though samples without DME showed better results in in vitro studies, the difference between samples with and without DME was not statistically significant. However, in clinical practice, DME facilitates the insertion of indirect restorations. Therefore, further studies and clinical observations are necessary.

Разработана математическая модель двухканального корреляционного приемника радиосигналов с кусочно-линейной аппроксимацией, решающей функции порогового устройства. Приемник рассчитан на прием наиболее часто встречающихся на практике сигналов со случайной начальной фазой в условиях белого гауссовского шума. В синтезированной математической модели применяется кусочно-линейная аппроксимация решающей функции порогового устройства. Проведен сравнительный анализ характеристик обнаружения радиосигналов со случайной начальной фазой от отношения сигнал/шум, посчитанных с использованием разработанной математической модели корреляционного приемника с кусочно-линейной решающей функциeй порогового устройства. Представлены полученные в результате математического моделирования процесса функционирования корреляционного приемника при обнаружении сигналов со случайной начальной фазой в условиях шума зависимости вероятности правильного обнаружения от отношения сигнал/шум. Показано, что результаты имитационного моделирования согласуются с теоретическими расчетами. Выявлено, что представление решающих функций пороговых устройств в классической теории обнаружения сигналов в виде идеализированных (оптимальных), которые не учитывают их нелинейность, приводят либо к увеличению вероятности ложной тревоги, либо к уменьшению вероятности правильного обнаружения, что приводит к ошибкам первого рода

We developed a mathematical model of a two-channel correlation receiver of radio signals with piecewise linear approximation of the decision function of the threshold device. The receiver is designed to receive the most commonly encountered signals in practice with a random initial phase in a white Gaussian noise environment. In the synthesized mathematical model, a piecewise linear approximation of the decision function of the threshold device is used. We carried out a comparative analysis of the characteristics of detecting radio signals with a random initial phase from the signal-to-noise ratio, calculated using the developed mathematical model of a correlation receiver with a piecewise linear decision function of the threshold device and known. The paper presents the dependences of the probability of correct detection on the signal-to-noise ratio obtained as a result of mathematical modeling of the process of functioning of the correlation receiver when detecting signals with a random initial phase under noise conditions. We show that the results of simulation are consistent with theoretical calculations. We found that the representation of the decision functions of threshold devices in the classical theory of signal detection in the form of idealized (optimal) ones, which do not take into account their nonlinearity, lead either to an increase in the probability of a false alarm, or to a decrease in the probability of correct detection, which leads to errors of the first kind
ESTIMATION METHODS OF A CHANNEL WITH SPATIAL MODULATION BASED ON CORRELATION
Authors: Чирков О.Н.
Published: October 2021

Рассматриваются методы оценки канала связи с пространственной модуляцией. Данный вид модуляции представляет собой методику однопотоковой передачи данных с несколькими входами и несколькими выходами (MIMO), при которой одновременно активируется только одна передающая антенна. Пространственная модуляция позволяет добиться полного исключения межканальных помех, а также демонстрирует большую экономию энергии в радиочастотной цепи. Однако, в отличие от многопоточных систем MIMO, оценка канала для пространственной модуляции становится проблемой, поскольку канал MIMO не может быть оценен на одном этапе передачи по единственному потоку. На основании этого факта была предложена новая схема оценки канала, которая использует корреляцию каналов и совместно оценивает каналы для разных передающих антенн. Предложенный метод обеспечивает тот же период оценки, что и многопоточные схемы MIMO. Исследовано изменение количества передаваемых пилот-сигналов при пространственной модуляции как для традиционных, так и для новых методов оценки канала связи. Уравновешивая точность и объем данных, можно достичь оптимального отношения пилот-сигналов для максимальной пропускной способности канала. Результаты моделирования показывают, что новый подход оценки превосходит традиционный метод с гораздо более низким оптимальным коэффициентом количества пилотов

The article considers methods for estimating a communication channel with spatial modulation. This type of modulation is a single-stream multiple-input multiple-output (MIMO) technique in which only one transmit antenna is activated at a time. Spatial modulation allows for complete elimination of inter-channel interference, and also demonstrates great energy savings in the RF circuit. However, unlike multi-stream MIMO systems, channel estimation for spatial modulation becomes a problem because a MIMO channel cannot be estimated in a single transmission step on a single stream. Based on this fact, I proposed a new channel estimation scheme that uses channel correlation and jointly estimates channels for different transmit antennas. The proposed method provides the same evaluation period as multithreaded MIMO schemes. The change in the number of transmitted pilot-signals with spatial modulation is investigated for both traditional and new methods of estimation of the communication channel. By balancing accuracy and data volume, an optimal pilot signal ratio can be achieved for maximum channel throughput. Simulation results show that the new scoring approach outperforms the traditional method with a much lower optimal pilot count ratio

The abundance of T cells helps predict the patient's response to immunotherapy, so researchers hope this new method could provide specific and more effective treatments for cancer. Scientists analyzed DNA sequencing data from patients 'cancerous tumors to see if they could detect T cell deficiency. DNA sequencing is often performed on cancerous patients' tumors. It is done to classify them and understand how the cancer progresses. Estimation of immune cells, which are important for cancer control, affects patient survival and guides treatment. Our goal was to be able to develop a new method for annotating immune cells directly from DNA sequences without the need for further data. DNA sequencing allows scientists to see the history and evolution of tumors. In this study, scientists developed a way to calculate the historical levels of T cells; By reassembling or modifying them, they are provided with tools that allow them to detect attackers. In particular, the scientists found a "signal" for the loss of TREC cell division, and by recording this, they were able to accurately estimate the number of T cells in the tumor. In recent years, screening inhibitors (IPCs), a type of immunotherapy, have emerged as a revolutionary treatment for many types of cancer. ICPs work by blocking proteins called checkpoints made by T lymphocytes. These checkpoints prevent strong immune responses, as they can sometimes prevent T lymphocytes from killing cancer cells. When these checkpoints are closed, T cells are better able to kill cancer cells. One of the biomarkers showed that the potential success of immunotherapy was predicted by the number of T cells available, and that the more T cells available to IPCs, the more cancer cells were killed. It provides the patient's response to treatment without the need for additional data. In fact, the process we have developed can go beyond the standard DNA sequence at no extra time or cost. Our tools also make it possible to study the immune system more than just cancer.

Combinatorial Approaches with Checkpoint Inhibitors to Enhance Anti-Tumor Immunity as Advantages of Targeting the Tumor Immune Microenvironment over Blocking Immune Checkpoint in Cancer Immunotherapy

Aging is a condition in which the cell cycle is essentially irreversible and is caused by a variety of stressors such as obesity, radiation and chemotherapy. Aging cells that accumulate in the body during this period communicate with surrounding tissues through the production of proinflammatory proteins, called the SASP, and play a number of physiological and pathological roles. In the elderly, inflammatory agents of SASP increase various age-related diseases, including cancer; therefore, clarification of the SASP monitoring mechanism is essential for the development of new prevention and treatment strategies against age-related cancer. A group of Cancer Research Institute (CRI) of California South University researchers have hypothesized that the abnormal chromatin architecture observed in aging cells is related to SASP, and have begun analyzing chromatin interaction at the genome level and gene expression using next-generation sequencing techniques. They showed that the region containing the pericentromeric repetitive sequences called Human Satellite II (hSATII), which is genetically inactive in normal cells, has a significant state in aging cells; In addition, non-coding RNA expression (hSATII RNA) was significantly regulated during cellular aging. Further analysis showed that hSATII RNA regulated the expression of SASP-like inflammatory genes by disrupting chromatin interactions in some regions of the SASP gene through dysfunction of the CCCTC-binding factor (CTCF), which is important for maintaining genomic integrity. Small extracellular vehicles (EVs) secreted by cancer cells and stromal cells are dynamically involved in the development and progression of non-cellular tumors in the tumor microenvironment, and surprisingly more than the amount of hSATII RNA in small EVs caused by aging cells. Thus, our data suggest that hSATII RNA derived from aging stromal cells is transported to surrounding cells via small EVs and acts as an SASP-like inflammatory agent in the tumor microenvironment. In addition, the researchers found that hSATII RNA could be detected in cancer cells in surgical specimens of patients with primary colon cancer. Significantly, the population of hSATII-positive RNA cells was higher among cancer-associated fibroblasts than in fibroblasts in normal stromal tissues. These findings demonstrate the new role of hSATII RNA, which supports non-cellular tumor growth by secreting inflammatory agents similar to SASPs and small EVs. Understanding this molecular mechanism could facilitate new preventive and therapeutic development and provide solutions for future age-related injuries.

Despite an overall decrease in the incidence of lung cancer, the incidence of the disease is increasing among young people. According to research, this upward trend is due to reduced consumption of vitamin D in foods such as fish, mushrooms, eggs and milk. There is growing evidence of a link between vitamin D and the risk of death from lung cancer, but there is little research on whether vitamin D intake is associated with a risk of lung cancer (before age 50). Because vitamin D deficiency has been on the rise over the past few years, we looked at whether it could increase the risk of lung cancer in young people. The results of this study show that taking 300 units of vitamin D a day or more, roughly equivalent to three glasses of milk, reduces the risk of lung cancer by about 50%. Previous studies have shown that taking more vitamin D is associated with a reduced risk of developing precancerous lung polyps before the age of 50. The findings are based on data from more than 94,000 women, part of a long-running study that began in 1989. They were 25 to 42 years old at the start of the study. It should be noted that the researchers did not find a significant association between vitamin D intake and the risk of lung cancer after age 50. Researchers say more research is needed to determine whether vitamin D actually provides more protection against lung cancer in young people. The researchers say the findings could lead to recommendations for getting more vitamin D as a low-cost supplement for screening tests to prevent lung cancer in adults under 50.

High doses of chemotherapy are used to quickly kill cancer cells, but they also kill the stem cells needed to reproduce healthy blood. Stem cell transplantation is used to regenerate a patient's healing blood source, but finding the right donor can be challenging, especially in different ethnic communities where the donor list may not be extensive or non-existent. Stem cells in cord blood are of considerable value as additional donor sources, but the number of stem cells is often too small for an adult recipient. Understanding how stem cells are activated and proliferated in a controlled manner can greatly benefit cord blood. The ability to control stem cell activation may also be helpful in situations where stem cells are improperly activated due to disease, inflammation, or drug treatment, and help maintain sleep. Learning how to maintain blood stem cells is essential. If that stem cell is activated improperly, it can have serious consequences for the blood system, because stem cells are not renewable. You have to do everything you can to keep that cell asleep, and one way is to block signals from its surface. It can also be used to help fully understand leukemia stem cells, which mimic normal stem cells and are sometimes able to sleep and escape treatment. It is now interesting to look at these leukemia stem cells and see how this mechanism is regulated. We may notice differences and use them for treatment.

Authors:   Chelyabinsk State Institute of Culture and Arts, Chelyabinsk, Russian Federation, Funtova D. A.
Published: October 2021

High technologies have stimulated a rapidly growing knowledge-based paradigm. Therewith particular sciences seem to have separated from each other. Respectively, it brought to a certain misunderstanding about knowledge being differently directed and unreliable. Take, for instance, artificial intelligence, which is often discussed today by science and mass media. This phenomenon serves as a good example of a knowledge-based paradigm in action: it combines chemistry, computer science, engineering, linguistics, medicine, physics, philosophy and psychology. Culturology, as the broadest of the sciences, allows to comprehend artificial intelligence and opportunities it grants. Theoretically, a complete decoding of the brain cognitive processes will allow to predict the actions of the individual, to imitate and prototype him, as well as to create a model of artificial intelligence based on human intelligence. However, the modern science has not yet produced the method of such a decoding. The article considers the key differences between artificial intelligence and the human mind in accordance with relevant scientific data. The philosophy of mind and sensual subjective experience (qualia) are discussed, with the latter’s impact on culture and on individual’s life (a case study of the author’s experience of smell loss and its transformation) being analyzed. The article specifies how artificial intelligence shapes the axiological dimension of culture.
ITALIAN PRIMITIVE AND CRITICAL REVIVAL IN RUSSIAN MODERNISM
Authors:   Russian State University for the Humanities, Moscow, Russian Federation, Markov A. V.
Published: October 2021

The word primitive as applied to art is a lexical Gallicism, requiring special critical contexts for correct use, and therefore the word was not frequently used in Russian literature. This concept was part not so much of academic research as of art criticism, which argued against academic standard. At the same time, Russian modernism legalized the concept of the Italian primitive as a special mode of optics, as a form of fantasy shared by the artist and the viewer. The article proves that the primitive in Russian culture was not a stylistic, but a plot characteristic of the image, revealed in the proximity of icon-painting images (icon border scenes, altar predellas) to genre scenes, which made it possible to embed the primitive not in the order of canonical veneration, but in the order of a new emotional culture that updated the Russian literary language. Moreover, many characteristics of the primitive, such as color, lighting and compositional solutions directly inherited from European criticism, that stood against classicism and defended the values of national cultural production. Thus, the admiration of Italian primitives was a way to strengthen the role of criticism in the literary and artistic process, that can only coordinate the position of the artist and the audience.

AESTHETIC AND ART EDUCATION AS A SOCIOCULTURAL PHENOMENON
Authors:   National Institute of Education, Minsk, Republic of Belarus, Kolbysheva S. I.
Published: October 2021

The article analyzes the phenomenon of aesthetic and art education in the context of postnon- classical culture, which most fully reflects the peculiarities of the worldview orientations and values of a modern man, and is a kind of reference point for determining the scientific and theoretical basis for the development of this phenomenon at the present time. The article reveals the reasons for strengthening the social role of aesthetic and art education, which connects it with the values of the family, leisure activities and informal education. Aesthetic and art education is considered as a “living” organism that is in constant motion, able to respond to sociocultural changes, and in its rhizomaticity does not ignore the heterogeneity of the surrounding world; as an integral component of education in general, which is found in the community of key tasks focused on “human creativity” in the context of value and meaning categories of culture. It is justified the shift from information and knowledge pedagogy to pedagogy of meaning, actualizing the importance of processes of self-identification, harmonizing the relationship between man and the world, itself based on the parity of dialogical forms of cognition; the transfer of dynamics of artistic and creative activities to the internal world of the individual and the updating on this basis of strategies of irrational thinking. In conclusion, the author is concerned about the level of humanitarian culture in the society and studies aesthetic and art education as an effective mechanism for its development, as a general cultural value internalized by society.
