Published: July 2023

Abstract
Aiming at the problems of low accuracy and time-consuming, combined with the characteristics of students' mutual obstruction and small activity space, a student pose tracking model based on filter with first and latest frames in classroom video is proposed, established a 14-point human pose representation module to represent the unobstructed joints’ information with fewer parameters, in order to reduce data redundancy and improve the model calculation speed and tracking accuracy, the human pose filtering module was constructed to remove the invalid pose that detects errors and detect duplicate in-frame redundant poses, and through the FL-Track module is used to match the target students with information of the student's first skeleton and the latest frame to comprehensively calculate the similarity of the students in different frames by using IOU and greedy algorithms. the experimental results on the classroom student pose tracking dataset created show that in the same experimental environment, compared with the SOTA, FFL-Track’s accuracy is increased by 5.94\%, and the frame rate is increased by 1.2fps, which greatly reduces the reasoning time and provides a great foundation for the downstream tasks in the classroom scene.

Does e-commerce ease or intensify tax competition? Destination principle vs. origin principle
Authors: Aiura Hiroshi , Ogawa Hikaru 
Published: July 2023

Abstract
This study examines the relationship between the development of e-commerce and the intensity of commodity tax competition under two different tax principles on goods purchased online: the destination principle and the origin principle. Our main findings are as follows: Given that origin-based tax is applied to purchases made in brick-and-mortar stores, (i) tax competition under destination-based taxation on e-commerce is more intense than tax competition under origin-based taxation; (ii) tax competition under origin-based tax on e-commerce generates higher tax revenues; and (iii) the development of e-commerce raises the tax rate and tax revenues under origin-based taxation but lowers them under destination-based taxation. The main factor leading to these results is that replacing the choice of “where to purchase” goods, consumers will have a new choice of “how to purchase” when online purchasing becomes available, and the destination-based taxation distorts the latter choice, while the origin-based taxation is neutral to it. Tax competition between asymmetric regions has also been analyzed, showing that both principles result in higher tax rates and greater tax revenues for large regions than for small ones.

Published: July 2023

Abstract
This paper focus on a kind of managerial decision-making problem with characteristics of interactive correlation and series relation from the realistic medical problems of traditional Chinese medicine (TCM) clinical diagnosis, and constructs a model based on the Choquet integral, multi-granulation fuzzy rough sets and graph. The decision-making method has the following processes: Firstly, construct a serial rough set model for interactively associated serial decision-making information. Secondly, using the graph model, each decision path of the decision group is described, and a multi-granularity fuzzy graph model based on serial rough set is constructed. Thirdly, Multi-granularity graph information is fused by Choquet integral, and then the distribution function is introduced to describe the distribution rule of uncertain vertex set in the graph. At last, using the data of 155 patients with rheumatoid arthritis (RA) in Guangdong Provincial Hospital of Chinese Medicine, the paper gives the application principle and algorithm steps of the proposed theoretical model, verifies the scientificity and applicability of the proposal, and provides auxiliary decision support for clinical decision-making.
Ellipses and hyperbolas of decomposition of even numbers into pairs of prime numbers
Authors: Butov Gennady 
Published: July 2023

Abstract
This is just an attempt to associate sums or differences of prime numbers with points lying on an ellipse or hyperbola.
Certain pairs of prime numbers can be represented as radius-distances from the focuses to points lying either on the ellipse or on the hyperbola.
The ellipse equation can be written in the following form: |pk| + |pt| = 2n.
The hyperbola equation can be written in the following form: ||pk| - |pt|| = 2n.
Here pk and pt are prime numbers (p1 = 2, p2 = 3, p3 = 5, p4 = 7,...),
k and t are indices of prime numbers,
2n is a given even number,
k, t, n ∈ N.
If we construct ellipses and hyperbolas based on the above, we get the following:
1) there are only 5 non-intersecting curves (for 2n=4; 2n=6; 2n=8; 2n=10; 2n=16). The remaining ellipses have intersection points.
2) there is only 1 non-intersecting hyperbola (for 2n=2) and 1 non-intersecting vertical line. The remaining hyperbolas have intersection points.

Published: July 2023

El objetivo de esta investigación fue determinar el impacto del confinamiento producido por la covid-19 sobre la autopercepción de habilidades digitales del siglo XXI en estudiantes de educación superior. La metodología consistió en un estudio longitudinal, analizando la autopercepción de estas habilidades antes de la pandemia y después de levantar el confinamiento. Los datos se obtuvieron mediante la aplicación una encuesta a muestras de 356 y de 2072 estudiantes antes y después del confinamiento, respectivamente. Se realizó análisis de componentes principales con rotación varimax. Los resultados muestran que la forma de trabajar durante la pandemia impactó positivamente en la autopercepción sobre las habilidades digitales del siglo XXI a estudiantes de educación superior, pues aumentó casi 14%. La limitante del estudio fue que solo se analizaron dos mediciones, por lo que aún no se puede definir una tendencia. Se concluye que el estudiantado ha acogido las TIC como un medio natural para comunicarse y colaborar de forma no presencial para resolver problemas académicos, por lo que el camino apunta hacia la creación y el fortalecimiento de metodologías y técnicas que aprovechen esta inercia en contextos educativos no presenciales y mixtos.
Multi-agent reinforcement learning framework for real-time scheduling of pump and valve in water distribution networks
Authors: Hu Shiyuan , Gao Jinliang , Zhong Dan 
Published: July 2023

Abstract

With energy and water resources shortages, the energy and water resources managements of water distribution networks (WDNs) have become increasingly important. However, achieving real-time scheduling of pump and valve in dynamic environments remains challenging. Thus, this study proposes a multi-agent reinforcement learning scheduling framework to address the uncertainty of water demand in WDNs. First, we constructed a WDN environment and modelled the scheduling problem as a Markov decision process. Second, a multi-agent deep deterministic policy gradient (MADDPG) method was used to determine the strategy of the fully cooperative multi-agent task. Moreover, the impacts of energy and water loss costs on the scheduling strategy were explored. Finally, the results were compared with those of a genetic algorithm (GA), particle swarm optimisation (PSO), and differential evolution (DE) to verify the performance and robustness of the proposed model. The results show that water loss dominates the scheduling process, and the scheduling solutions for minimising water loss and energy costs are mainly affected by the demand pattern of consumers rather than the energy tariff. The proposed MADDPG model outperforms the GA, PSO, and DE models, achieving a significantly faster solution, which is advantageous for practical applications.

Background
While mobile health apps have demonstrated their potential in revolutionizing health behavior changes, the impact of a mobile community built on these apps on the level of physical activity and mental well-being in cancer survivors remains unexplored.

Objective
In this randomized controlled trial, we examine the effects of participation in a mobile health community specifically designed for breast cancer survivors on their physical activity levels and mental distress.

Methods
We performed a single-center, randomized, parallel-group, open-label, controlled trial. This trial enrolled women between 20 and 60 years of age with stage 0 to III breast cancer, an Eastern Cooperative Oncology Group performance status of 0, and the capability of using their own smartphone apps. From January 7, 2019, to April 17, 2020, a total of 2,616 patients were consecutively screened for eligibility after breast cancer surgery. Overall, 202 patients were enrolled in this trial, and 186 patients were randomly assigned (1:1) to either the intervention group (engagement in a mobile peer support community using an app for tracking steps; n=93) or the control group (using the app for step tracking only; n=93) with a block size of 10 without stratification. The mobile app provides a visual interface of daily step counts, while the community function also provides rankings among its members and regular notifications encouraging physical activity. The primary end point was the rate of moderate to severe distress for the 24-week study period, measured through an app-based survey using the Distress Thermometer. The secondary end point was the total weekly steps during the 24-week period.

Results
After excluding dropouts, 85 patients in the intervention group and 90 patients in the control group were included in the analysis. Multivariate analyses showed that patients in the intervention group had a significantly lower degree of moderate to severe distress (B=–0.558; odds ratio 0.572; P<.001) and a higher number of total weekly step counts (B=0.125; rate ratio 1.132; P<.001) during the 24-week period.

Conclusions
Engagement in a mobile app–based patient community was effective in reducing mental distress and increasing physical activity in breast cancer survivors.

Published: July 2023

El sistema nacional de salud es un mecanismo por el cual los Estados buscan garantizar la protección de la salud de sus ciudadanos, teniendo cada país su sistema de salud. En determinadas ocasiones este sistema es sometido a exigencias extremas, como un desastre natural o una pandemia, así como la que el mundo está pasando con el COVID-19. Los países que tienen sólidos sistemas de salud basados en la atención primaria de salud (lo que se refleja en cobertura a todos sus ciudadanos, protección financiera y adecuada prevención y promoción de la salud) tienen un mejor desempeño ante estas demandas extremas. Esta capacidad de respuesta del sistema nacional de salud del Ecuador se estudió a propósito del terremoto de Pedernales que ocurrió en la provincia de Manabí, el 16 de abril del 2016, y en que murieron 663 personas (1), afectando el funcionamiento de varias unidades médicas del Ministerio de Salud Pública (MSP), incluido el hospital de Chone, lugar donde se realizó un estudio (2) financiado por la Universidad Católica de Santiago de Guayaquil que evidenció los programas, gestión y acciones que el MSP debía mejorar para proteger adecuadamente a la población ante eventos similares que se presenten en el futuro. Se hizo una triangulación de metodologías documentales, cualitativas y cuantitativas. La información epidemiológica y de producción de servicios fue sistematizada de documentos oficiales, las entrevistas en profundidad se realizaron a directores de programas de salud y técnicos del MSP. La visión de los usuarios sobre la atención de salud antes y después del terremoto, fue recogida con encuestas a los usuarios de las unidades de salud.

Background. According to current concepts regarding hepatic fibrosis, myofibroblast differentiation from stellate cells, regulated by transforming growth factor-β (TGF-β), is a key step in its pathogenesis. Hence, inhibition of TGF-β-dependent activation of hepatic stellate cells has been suggested as a promising strategy for preventing the disease development.Aim. To explore whether the administration of fucoxanthin at a dose of 30 mg/kg is efficient in suppressing hepatic fibrosis.Materials and Methods. The experiments were carried out on 30 outbred ICR/CD1 mice which have been divided into three groups: intact animals, animals with untreated hepatic fibrosis which has been induced by intraperitoneal injections of CCl4 (2 μl/g, 6 weeks, twice per week), and animals which received fucoxanthin per os (30 mg/kg daily for 5 weeks) after inducing hepatic fibrosis as described above. Histological examination was performed by Sirius Red staining using the METAVIR fibrosis and activity score. Immunohistochemical analysis was performed by quantitation of α-SMA-positive myofibroblasts, CD45-positive leukocytes, and TIMP-1-positive regions. Further, we quantified TGF-β in liver homogenate as well as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the serum by means of enzyme-linked immunosorbent assay. An assessment of liver function was conducted by measuring serum alanine aminotransferase, aspartate aminotransferase, and albumin levels.Results. Fucoxanthin decreased the number of myofibroblasts and leukocytes, the volume of connective tissue and TIMP-1-positive regions, and the level of TGF-β in the liver homogenate, altogether indicative of ameliorated hepatic fibrosis. In accord, treatment with fucoxanthin reduced serum IL-1β, TNF-α, alanine aminotransferase and aspartate aminotransferase, and increased serum albumin.Conclusion. Treatment with fucoxanthin at a dose of 30 mg/kg has an antifibrotic effect and diminishes liver fibrosis.

Published: July 2023

AbstractThis paper examines the wealth collector in Surah al-Humazah, where they frequently disregard their obligation to worship God and are continually focused on multiplying their riches until they believe all they acquire could make them eternal. They believe they have abundant wealth, so they easily belittle others. This study employed a literature review method based on Ferdinand de Saussure's semiotic theory approach. The stages of the approach are syntagmatic analysis, paradigmatic analysis, binary opposition, and history confirmation. According to the findings of this study, there is coherence between verses in the Surah al-Humazah when using syntagmatic analysis. Second, wealth collectors are those with immoral tendencies who like to curse and blame. Also, they believe that their fortune would be able to eternalize them, making them hesitant to share. Hence, they threatened with hell huthamah. Furthermore, Surah al-Humazah has a secret message for every Muslim to practice social charity to create harmony among individuals in society.Keywords: al-Humazah; Binary opposition; Paradigmatic; syntagmatic. AbstrakTulisan ini membahas pengumpul harta yang ada dalam surat al-Humazah di mana pengumpul harta sering lalai dengan kewajiban ibadah kepada Tuhan dan selalu terfokus pada cara memperbanyak harta hingga mereka mengira harta yang mereka kumpulkan dapat mengekalkannya, merasa memiliki harta yang banyak sehingga mereka dengan mudahnya merendahkan orang lain. Penelitian ini menggunakan metode studi pustaka dengan pendekatan teori semiotika dari Ferdinand de Saussure dengan langkah yang pertama analisis sintagmatik, kedua analisis paradigmatik, ketiga oposisi biner, keempat mengkonfirmasi sejarah. Hasil dari penelitian ini adalah dengan analisis sintagmatik dalam surat al-Humazah terdapat koherensi antar ayat. Kedua, pengumpul harta ialah mereka yang memiliki sifat amoral yang suka mengumpat dan mencela serta menganggap hartanya dapat mengekalkannya sehingga enggan berinfak akibatnya mereka diancam dengan neraka huthamah. Selain itu surat al-Humazah memiliki pesan tersembunyi, yaitu agar setiap muslim beramal sosial dalam kehidupan bermasyarakat sehingga dalam bermasyarakat terjalin kerukunan antar sesama. Kata Kunci: al-Humazah; Oposisi Biner; Paradigmatik; Sintagmatik.
