Published: December 2024

The article analyzes the interaction of classical universities with educational platforms. The main forms of interaction and functionality typical for marketplaces are high-lighted. The analysis showed that the transition to online education, including through educa-tional platforms, carries new opportunities rather than threats to higher education institutions. It has been established that, in the classical sense, educational marketplaces have not yet been formed, their creation on the basis of established digital ecosystems with a strong brand could contribute to the formation of new channels for the promotion of educational services, imple-mented both online and in online formats.

ECOLOGICAL WELL-BEING IN THE REGIONS OF THE ARCTIC FEDERAL DISTRICT: ENHANCING SAFETY AND BALANCE
Authors:   Federal Research Center “Computer Science and Control” of the Russian Academy of Sciences Moscow, Russian Federation, Voronina Elena P.
Published: December 2024

In modern conditions, with the dynamic ecological transformation of all spheres of society, there is a growing understanding of the importance of socio-ecological-economic de-velopment, which must focus clearly on achieving harmony between society and nature, ulti-mately taking on the character of eco-development. This assertion is particularly relevant for the Arctic regions of Russia. Despite measures taken by governmental bodies to ensure environmen-tal safety and protect the environment, a high level of ecological tension is still observed. The article highlights key trends in the socio-ecological-economic development of territories within the Arctic Federal District (AFD) and identifies major problems. A comparative analysis based on statistical data regarding the implementation of regional projects within the framework of the national project «Ecology» supports the argument that, to achieve ecological well-being and high indicators of socio- ecological-economic development in the Arctic regions of the Russian Federation, it is essential to apply the principles of ecological transformation, develop policies for ensuring environmental safety, and enhance the effectiveness of ecological activities.
FORMATION AND IMPLEMENTATION OF THE PROCESS OF REGULATION OF REGIONAL DIFFERENTIATION OF SOCIAL AND ECONOMIC DEVELOPMENT
Authors:   Russian University of Cooperation, Mytishchi, Russian Federation, Repushevskaya Olga A.
Published: December 2024

In this paper, a set of tools was formed based on existing methods of socio-economic regional development in order to manage the process of changing the indicator of dif-ferentiation of the level of regional development. It was also concluded that these tools can be used to improve consistency within regional regulation. The problem is currently progressing - regions show a decrease in the level of consistency of both internal and external processes, which occurs due to regional differentiation. It should be noted that this differentiation is developing unevenly in all regions, which is explained by the difference in the following factors: human capital, the state of natural resources, infrastructure, etc. In this case, regions focus only on one or several industries of their advantage, developing them, which negatively affects the sustaina-bility of other industries. In this regard, the development of measures for analyzing the level and characteristics of a certain regional differentiation, which will become the basis for forming a development strategy, is of high relevance.

The scientific article examines the current problems of local taxes and fees in the context of formation of local budgets revenues in the Russian Federation.
It is quite obvious that the reforms carried out in Russia have demonstrated that gaps in the tax system are one of the significant reasons for controversial issues in the state of the coun-try's economy. Of course, this required the development of a new fiscal policy, which plays a major role in the system of measures of state influence on the economic situation in the country.
The article pays attention to the problematic aspects of local taxes. It is no secret that at all times, states have actively sought to organize effective control with the help of fiscal instru-ments. And, according to the authors, our country is no exception. The scientific article summa-rizes the functional components of local taxes, as one of the most important taxes in the tax system of the Russian Federation in the context of the formation of local budget revenues.
It is noted that taxation is a rather complex and sometimes contradictory process. It is important to maintain a balance between the interests of the state and the taxpayer. But the main strategy in this aspect, of course, should be the human life of every citizen of our country, its quality, duration and completeness.

The Tax Code prescribes all measures of collection of arrears on taxes and fees, as well as penalties and fines. The article describes how the Federal Tax Service and the Federal Bailiff Service of Russia interact. In what timeframes and in what cases they apply to the courts. In order to protect the rights and legally protected interests of the parties to enforcement pro-ceedings, other persons associated with the execution of a jurisdictional act, as well as state or public interests, compulsory execution can be carried out only in the forms determined by law. Based on this, the study of problems arising in the application of compulsory enforcement measures and amendments to the legal framework does not lose relevance at all times. The rel-evance of the chosen topic of the article is due to the fact that issues related to enforcement proceedings are among the most widely discussed in recent years in the legal literature. They touch upon the problem of the effectiveness of the state's protection of the rights, freedoms and legitimate interests of citizens and organizations. This protection is an important guarantee of human and civil rights and freedoms, proclaimed in Article 45 of the Constitution of the Russian Federation. A successful lawsuit may lose all meaning if there is no real opportunity to implement the court decision.
The article examines the issues of tax origin. Issues regulating tax legislation are covered. The concept of enforcement measures is also given, as well as the types of enforce-ment measures are presented. The article describes the interaction of the Federal Tax Service and the Federal Bailiff Service, the legal basis for their interaction. Enforcement measures pro-vided for by the Tax Code of the Russian Federation are described. This work covers in detail the issues of debt settlement. provided for by the Tax Code of the Russian Federation.

Authors: Wang Yixin , Han Jie
Published: December 2024

Jia County, located in Pingdingshan City, Henan Province, is one of China’s historical cities, known for its prosperous economy and thriving community of merchants and traders. Recognizing Jia County’s geographical advantages, merchants from Shanxi and Shaanxi Provinces, renowned for their business acumen, funded the construction of the Shanxi-Shaanxi Guild Hall in 1693. This guild hall served as a multifunctional hub for business negotiation, sacrificial rituals to honor the gods, hospitality for guests, and fostering connections among Shanxi and Shaanxi businessmen, strengthening the exchange of economic and trade information. As an important architectural heritage site along the cultural route of the Great Tea Route, the Shanxi-Shaanxi Guild Hall holds immense historical and cultural value. The local government has initiated plans to preserve it as a public space for future generations. This article examines the Shanxi-Shaanxi Guild Hall in the context of the Great Tea Route as a cultural route. Drawing on archival research, field investigations, and semi-structured interviews, it delves into Shanxi-Shaanxi Guild Hall’s tangible and intangible cultural characteristics and its historical relationship with the Great Tea Route. By uncovering the deeper value connotation of the Shanxi-Shaanxi Guild Hall, this study aims to provide new insights into the conservation of cultural heritage.

($\overrightarrow{P_6}$, triangle)-Free Digraphs Have Bounded Dichromatic Number
Authors: Aboulker Pierre , Aubian Guillaume , Charbit Pierre , Thomassé Stéphan
Published: December 2024

The dichromatic number of an oriented graph is the minimum size of a partition of its vertices into acyclic induced subdigraphs. We prove that oriented graphs with no induced directed path on six vertices and no triangle have bounded dichromatic number. This is one (small) step towards the general conjecture asserting that for every oriented tree $T$ and every integer $k$, any oriented graph that does not contain an induced copy of $T$ nor a clique of size $k$ has dichromatic number at most some function of $k$ and $T$ .
Mixed Dimer Configuration Model in Type D Cluster Algebras II: Beyond the Acyclic Case
Authors: Farrell Libby , Musiker Gregg , Wright Kayla
Published: December 2024

This is a sequel to the second and third author's Mixed Dimer Configuration Model in Type D Cluster Algebras where we extend our model to work for quivers that contain oriented cycles. Namely, we extend a combinatorial model for F-polynomials for type D using dimer and double dimer configurations. In particular, we give a graph theoretic recipe that describes which monomials appear in such F-polynomials, as well as a graph theoretic way to determine the coefficients of each of these monomials. To prove this formula, we provide an explicit bijection between mixed dimer configurations and dimension vectors of submodules of an indecomposable Jacobian algebra module.
$K_r$-Saturated Graphs and the Two Families Theorem
Authors: Calbet Asier
Published: December 2024

We say that a graph $G$ is $K_r$-saturated if $G$ contains no copy of $K_r$ but adding any new edge to $G$ creates a copy of $K_r$. Let $sat(n,K_r,t)$ be the minimum number of edges in a $K_r$-saturated graph on $n$ vertices with minimum degree at least $t$. Day showed that for fixed $r \geq 3$ and $t \geq r-2$, $sat(n,K_r,t)=tn-c(r,t)$ for large enough $n$, where $c(r,t)$ is a constant depending on $r$ and $t$, and proved the bounds $$ 2^t t^{3/2} \ll_r c(r,t) \leq t^{t^{2t^2}} $$for fixed $r$ and large $t$. In this paper we show that for fixed $r$ and large $t$, the order of magnitude of $c(r,t)$ is given by $c(r,t)=\Theta_r \left(4^t t^{-1/2} \right)$. Moreover, we investigate the dependence on $r$, obtaining the estimates$$ \frac{4^{t-r}}{\sqrt{t-r+3}} + r^2 \ll c(r,t) \ll \frac{4^{t-r} \min{(r,\sqrt{t-r+3})}}{\sqrt{t-r+3}} + r^2 \ . $$We further show that for all $r$ and $t$, there is a finite collection of graphs such that all extremal graphs are blow-ups of graphs in the collection.
Using similar ideas, we show that every large $K_r$-saturated graph with $e$ edges has a vertex cover of size $O(e / \log e)$, uniformly in $r \geq 3$. This strengthens a previous result of Pikhurko. We also provide examples for which this bound is tight.
A key ingredient in the proofs is a new version of Bollobás's Two Families Theorem.
The Minimum Number of Maximal Independent Sets in Twin-Free Graphs
Authors: Cambie Stijn , Wagner Stephan
Published: December 2024

The problem of determining the maximum number of maximal independent sets in certain graph classes dates back to a paper of Miller and Muller and a question of Erdős and Moser from the 1960s. The minimum was always considered to be less interesting due to simple examples such as stars. In this paper we show that the problem becomes interesting when restricted to twin-free graphs, where no two vertices have the same open neighbourhood. We consider the question for arbitrary graphs, bipartite graphs and trees. The minimum number of maximal independent sets turns out to be logarithmic in the number of vertices for arbitrary graphs, linear for bipartite graphs and exponential for trees. In the latter case, the minimum and the extremal graphs have been determined earlier by Taletskii and Malyshev, but we present a shorter proof.
In silico analysis of lncRNA-miRNA-mRNA signatures related to Sorafenib effectiveness in liver cancer cells
Authors: de la Cruz-Ojeda Patricia , Parras-Martínez Ester , Rey-Pérez Raquel , Muntané Jordi
Published: December 2024

BACKGROUND

Hepatocellular carcinoma (HCC) is the most common subtype of primary liver cancer with varied incidence and epidemiology worldwide. Sorafenib is still a recommended treatment for a large proportion of patients with advanced HCC. Different patterns of treatment responsiveness have been identified in differentiated hepatoblastoma HepG2 cells and metastatic HCC SNU449 cells.

AIM

To define the long non-codingRNA-microRNA-mRNA (lncRNA-miRNA-mRNA) predicted signatures related to selected hallmarks of cancer (apoptosis, autophagy, cell stress, cell dedifferentiation and invasiveness) in RNAseq studies using Sorafenib-treated HepG2 and SNU449 cells. Various available software analyses allowed us to establish the lncRNA-miRNA-mRNA regulatory axes following treatment in HepG2 and SNU449 cells.

METHODS

HepG2 and SNU449 cells were treated with Sorafenib (10 μmol/L) for 24 hours. Total RNA, including small and long RNA, was extracted with a commercial miRNeasy kit. RNAseq was carried out for the identification of changes in lncRNA-miRNA-mRNA regulatory axes.

RESULTS

MALAT, THAP9-AS1 and SNGH17 appeared to coordinately regulate miR-374b-3p and miR-769-5p that led to upregulation of SMAD7 , TIRARP , TFAP4 and FAXDC2 in HepG2 cells. SNHG12, EPB41 L4A-AS1, LINC01578, SNHG12 and GAS5 interacted with let-7b-3p, miR-195-5p and VEGFA in SNU449 cells. The axes MALAT1/hsa-mir-374b-3p/SMAD7 and MALAT1/hsa-mir-769-5p/TFAP4 were of high relevance for Sorafenib response in HepG2 cells, whereas PVT1 /hsa-miR-195-5p/VEGFA was responsible for the differential response of SNU449 cells to Sorafenib treatment.

CONCLUSION

Critical lncRNAs acting as sponges of miRNA were identified that regulated mRNA expression, whose proteins mainly increased the antitumor effectiveness of the treatment (SMAD7 , TIRARP , TFAP4 , FAXDC2 and ADRB2 ). However, the broad regulatory axis leading to increased VEGFA expression may be related to the side effect of Sorafenib in SNU449 cells.
Can Emax and platelet count truly differentiate between benign and malignant liver lesions?
Authors: Goyal Manjeet Kumar , Goyal Omesh
Published: December 2024

This letter critically evaluates Jiang et al 's article on the differentiation of benign and malignant liver lesions using Emax and platelet count. Despite notable findings, significant methodological and interpretative limitations are identified. The study lacks detailed assay conditions for Emax measurement, employs inadequate statistical methods without robust multivariate analysis, and does not provide clinically relevant threshold values. The nomogram's reliance on Emax as a major diagnostic contributor is questionable due to attenuation in hepatocellular carcinoma patients with cirrhosis. Moreover, the study's limitations, such as selection bias and confounding factors, are not adequately addressed. Future research should adopt more rigorous methodologies, including prospective studies with larger cohorts and standardized protocols for biomarker measurement, to enhance validity and clinical applicability.

Authors: Гасникова А , Иванова М , Козьменко А , Козьменко С , Туинова С , Ульченко М , Щеголькова А
Published: December 2024

Показаны новые геополитические условия социально-экономического развития Арктики, которые сложились в результате обострения противостояния по линии «Россия — НАТО». Это обострение до «горячей фазы» воплотилось в региональном военном конфликте на территории Украины в форме специальной военной операции (геополитика) и масштабном санкционном давлении на Россию со стороны стран «коллективного Запада». Показано непосредственное влияние проводимой на Западе политики формирования однополюсного (американоцентричного) мироздания на мировую экономику и противодействие этим тенденциям глобального развития содружествами и альянсами крупных мировых держав, что в результате приведёт к закату глобализации.
Монографическое исследование раскрывает проблемы и перспективы развития российского арктического энергетического сектора. Рассмотрено современное состояние глобального рынка нефти и природного газа, определены основные тенденции в их развитии. Изучены вопросы, посвящённые освоению угольных запасов западной части Российской Арктики, а также современное состояние
и проблемы энергообеспечения в арктических регионах России.
Работа выполнена в рамках темы FMEZ–2023–0009 «Стратегическое планирование развития Арктики в новых геоэкономических и политических условиях» по государственному заданию Министерства науки и высшего образования РФ.
Издание может быть интересно и полезно широкому кругу научных и педагогических работников — исследователям в области региональной и отраслевой экономики в сфере освоения энергетических ресурсов и представляет собой весомый вклад в дальнейшее развитие арктических исследований, также может быть рекомендовано в качестве учебного пособия студентам и аспирантам соответствующих специальностей.

The purpose of this study is to determine the implementation of the learning cycle model in differentiated learning in science and science subjects in grade IV SDK St. Joseph 2 Naikoten. The type of research used by the researcher is qualitative research using a descriptive approach. The data collection techniques used by the researcher were interviews, observations and documentation with grade IV teachers, principals and students which produced data on the implementation of the learning cycle learning model in differentiated learning in science subjects in grade IV of SDK St. Joseph 2 Naikoten. The collection instruments in this study are observation sheets, interview guidelines or question sheets. The data was analyzed using the Miles & Huberman model with the sequence of steps of data collection, data reduction, data presentation, and conclusion drawn. The validity of the data in this study is carried out by increasing research and triangulation. The results of this study show that teachers do not experience difficulties in learning the learning cycle because they already understand the learning steps according to the existing syntax. The learning cycle model is suitable for educators in learning sciences, where students learn actively and learn material meaningfully by working and thinking. The implementation of the learning cycle learning model includes planning, implementation, and evaluation as follows: a) Learning planning, teachers prepare teaching modules student worksheets, analyze subject matter, determine learning media and learning resources. b) The implementation of learning is carried out in five stages, engagement (generating interest), exploration , explanation, elaboration (development), and evaluation. c) Learning evaluation is carried out using assessment instruments such as knowledge assessment, attitude, skills, and student learning activities. So it can be concluded that the learning cycle learning model can be applied in social studies learning because it makes students motivated to learn, cooperate, be responsible, understand the material easily and can improve student learning outcomes.

PKn learning is expected to be a vehicle for students to learn about themselves and the surrounding environment as well as prospects for further development in applying it in daily life. However, there are still many students who lack mastery of the material and obtain scores that have not reached the KKTP. This happens because the learning model used is usually a conventional learning model. In addition, it also identifies problems, namely First, the learning outcomes of PKN students have not reached KKTP, second, teachers tend to use conventional learning models where teachers teach more oriented to lecture methods so that learning is more teacher-centered. Third, the teacher's lack of attention to the student's ability to receive the material because it is chasing time so that the material is completed quickly. The purpose of this study is to determine the influence of  the continuous teaching learning  model on the learning outcomes of PKn in grade IV students of Oepura 4 Multi-level SDI, Kupang City. This type of research is a quantitative research classified as Quasi Experimental research, using a pretest posttest control group design. The sampling technique uses a saturated sampling technique with a sample of 30 respondents. The instruments used in this study are tests and documentation. The data was analyzed using data normality tests, homogination tests, linearity tests, and hypothesis tests. The results showed that the average posttest score of the experimental class and the control class posttest using the t-test was 78.33 > 1.50 with a difference of 15.82. Furthermore, through hypothesis testing (Independent Samples Tests) it was shown that the value of sig. (2-tailed) t-test for Equality of Means of 0.000<0.05 means that H0 is rejected and Ha is accepted. The conclusion of this study is the application of the significant influence of  the contexual teaching learning  model on the learning outcomes of PKn students in grade IV of SD Inpres Berstrata Oepura 4, Kupang City.

La musicoterapia se presenta como una nueva alternativa de tratamiento de fácil acceso y eficaz para reducir la sintomatología ansiosa. El objetivo de este estudio es analizar la influencia de la musicoterapia en la disminución de la ansiedad en pacientes diagnosticados con este trastorno, centrándose en identificar la música que muestra la mayor reducción en los niveles de ansiedad. Para ello, se realizó un estudio cuasi experimental, con dos mujeres, estudiantes universitarias del área de salud, de 21 y 24 años, ambas diagnosticadas con ansiedad. Cada una de ellas participó en 6 sesiones de musicoterapia, dos cada semana por tres semanas. La primera participante (participante 1) escuchó en cada sesión la música que le gusta. Mientras que la segunda participante (participante 2) escuchó música clásica. Se les practicó un pre-test y un post-test en cada sesión para medir el nivel de ansiedad mediante la Escala de Ansiedad de Beck. Los resultaron muestran que en la paciente 1 la reducción de los niveles de ansiedad fue significativamente mayor (de grave a leve) en comparación con la paciente 2 (de grave a moderada). Concluyendo que la musicoterapia es una herramienta eficaz para reducir los niveles de ansiedad en pacientes diagnosticados.

En el presente estudio se comparan los valores del hematocrito vs la estimación visual del sangrado como criterio diagnóstico de hemorragia obstétrica. Se realizó un estudio analítico, observacional, transversal, prospectivo en el servicio Ginecología y Obstetricia en el Hospital General de Zona No. 20, se analizaron los datos que se encontraron en el expediente clínico de la estimación visual del volumen del sangrado que se obtuvo post evento obstétrico y los valores del hematocrito plasmados en los laboratoriales post evento obstétrico, los cuales se expresaron con estadística analítica y prueba de t de Student. Los resultados muestran que el método de cuantificación visual del sangrado subestima el valor otorgado, por lo tanto también el número de pacientes que presentaron hemorragia obstétrica; siendo, la determinación del hematocrito un método por el cual se identificaron a un mayor número de mujeres con el diagnóstico de hemorragia obstétrica (p=0.0001). Se encontró que la determinación de la disminución del hematocrito vs los estimados mediante método visual muestra una tendencia a la subestimación debido a diferentes factores que producen sesgo estadístico y por lo tanto un resultado que se traduce a una estimación del volumen de sangrado inadecuado. Al utilizar la estimación de la hemorragia obstétrica mediante el hematocrito, se obtiene un resultado de mayor presentación de dicho evento, aunque simultáneamente intervienen factores los cuales pueden modificar el resultado final y a su vez sobrestimar o subestimar la cantidad de pérdida sanguínea.

El cannabidiol (CBD), el principal compuesto no psicoactivo que se encuentra en la Cannabis Sativa, se usa con frecuencia tanto como nutracéutico como terapéutico, debido a los efectos farmacológicos que incluyen antiinflamatorio, analgésico, antipruriginoso, ansiolítico, inhibidor del crecimiento tumoral y anticonvulsivo, propiedades que han hecho de él una opción de tratamiento atractiva para evitar o disminuir los efectos secundarios de los fármacos tradicionales. Sin embargo, debido a la escasez de estudios científicos sólidos prescripción en perros es limitada, el propósito de esta investigación es describir los beneficios terapéuticos del cannabidiol en caninos a través de una revisión bibliográfica para proporcionar fiabilidad para que los veterinarios informen a sus usuarios sobre el uso y la seguridad de los productos de CBD. Se consulta e identifica los reportes más relevantes del cannabidiol en perros, seleccionando así la información de su uso terapéutico, describiendo sus características, propiedades, dosificación, vías de administración y eventos adversos. Se discute con ensayos clínicos y resultados basado en evidencia experimental.

Lead-based radiation shielding material is currently used in industry to shield against high-penetration radiation such as gamma rays. However, lead is harmful to humans, animals, and plants. This study proposed a new composition of transparent lead-free glass. Using the melt and quench technique, thulium-doped bismuth tellurite glass with composition (TeO2)1-x (Bi2O3)x (Tm2O3)0.02 where x = 0.05, 0.10, 0.15, and 0.20 mol % was fabricated. Significantly, the glasses with Bi2O3 concentration of 5 mol % and 10 mol% have a higher density than the commercial glass containing lead indicating the fabricated glasses would perform better as a radiation shielding material. Comparing the simulated-radiation shielding properties using software Phy-X and XCom, the glass with 10 mol% of Bi2O3 performs better as radiation shielding material than 5 mol% of Bi2O3. Meanwhile, glass with 5 mol% of Bi2O3 performs better than 10 mol% of Bi2O3 in terms of optical properties. Considering both radiation shielding and optical properties, the fabricated lead-free glass can be widely used in radiation shielding applications that require transparency.

As population density rises, the need for potable water grows. Solar distillation is the method of transforming briny water into drinkable water. We use solar desalination to desalinate untreated water. People commonly apply the desalination process to obtain pure water using solar stills. The primary classifications of solar stills are active and passive. This work aims to boost productivity by experimentally implementing the condensation and evaporation processes inside the still. To achieve this, we incorporate a magnetic field and an external condenser into the traditional distillation apparatus. The findings indicate that the outputs of the traditional solar still, the traditional solar still with a magnetic field and an external condenser (CSS-MACO), and the traditional solar still with a magnetic field (CSS-MAG) are 3.800, 5.210, and 5.800 L/m2/day, respectively. Therefore, the utilization of a magnetic field results in a 52.63% increase in productivity, while the combination of a magnetic field and an external condenser leads to a 37.10% improvement, compared to the typical solar still. From a cost analysis perspective, incorporating a magnetic field alongside a conventional solar still is the most cost-effective choice in terms of the total expense per liter of pure water. To be more specific, the cost is 0.016 USD, which is 30.43% lower than the CSS cost.

The integration of high technology has brought unprecedented convenience and possibilities to higher education, but it has also brought various challenges. With the continuous innovation of technology, these advantages and challenges are constantly changing. However, the previous studies lack a systematic review and summary of these advantages and challenges of changes. Therefore, the purpose of this review is to integrate and analyze the relevant research results of higher education learning in the high-tech environment, to keep an eye on these changes, better grasp the impact of technology on the field of higher education, and insight into the future development trend of higher education. This systematic review uses 20 journal articles from (WoS) and Scopus from 2019 to 2023. The results of the survey show that students' learning ability is gradually enhanced, the academic atmosphere of colleges and universities is increasingly strong, and the learning opportunities provided by higher education are more and more diverse, which are the positive effects of high-tech progress on higher education. However, in the context of the rapid development of high technology, we should also pay attention to the adaptability of the teaching individual and the challenges faced by the inadequate preparation of society in terms of technical training and technical equipment at the macro level.
