On the well posedness of a mathematical model for a singular nonlinear fractional pseudo-hyperbolic system with nonlocal boundary conditions and frictional damping terms
Authors: Mesloub Said , Gadain Hassan Altayeb , Kasmi Lotfi
Published: January 2024

This paper is devoted to the study of the well-posedness of a singular nonlinear fractional pseudo-hyperbolic system with frictional damping terms. The fractional derivative is described in Caputo sense. The equations are supplemented by classical and nonlocal boundary conditions. Upon some a priori estimates and density arguments, we establish the existence and uniqueness of the strongly generalized solution for the associated linear fractional system in some Sobolev fractional spaces. On the basis of the obtained results for the linear fractional system, we apply an iterative process in order to establish the well-posedness of the nonlinear fractional system. This mathematical model of pseudo-hyperbolic systems arises mainly in the theory of longitudinal and lateral vibrations of elastic bars (beams), and in some special case it is propounded in unsteady helical flows between two infinite coaxial circular cylinders for some specific boundary conditions.

Published: January 2024

Driver drowsiness is one of the leading causes of road accidents resulting in serious physical injuries, fatalities, and substantial economic losses. A sophisticated Driver Drowsiness Detection (DDD) system can alert the driver in case of abnormal behavior and avoid catastrophes. Several studies have already addressed driver drowsiness through behavioral measures and facial features. In this paper, we propose a hybrid real-time DDD system based on the Eyes Closure Ratio and Mouth Opening Ratio using simple camera and deep learning techniques. This system seeks to model the driver's behavior in order to alert him/her in case of drowsiness states to avoid potential accidents. The main contribution of the proposed approach is to build a reliable system able to avoid false detected drowsiness situations and to alert only the real ones. To this end, our research procedure is divided into two processes. The offline process performs a classification module using pretrained Convolutional Neural Networks (CNNs) to detect the drowsiness of the driver. In the online process, we calculate the percentage of the eyes' closure and yawning frequency of the driver online from real-time video using the Chebyshev distance instead of the classic Euclidean distance. The accurate drowsiness state of the driver is evaluated with the aid of the pretrained CNNs based on an ensemble learning paradigm. In order to improve models' performances, we applied data augmentation techniques for the generated dataset. The accuracies achieved are 97 % for the VGG16 model, 96% for VGG19 model and 98% for ResNet50 model. This system can assess the driver's dynamics with a precision rate of 98%.
Huizhou resident population, Guangdong resident population and elderly population forecast based on the NAR neural network Markov model
Authors: Li Dewang , Qiu Meilan , Luo Zhongliang
Published: January 2024

We propose a nonlinear auto regressive neural network Markov model (NARMKM) to predict the annual Huizhou resident population, Guangdong resident population and elderly population in China, and improve the accuracy of population forecasting. The new model is built upon the traditional neural network model and utilized matrix perturbation theory to study the natural and response characteristics of a system when the structural parameters change slightly. The delay order and hidden layer number of neurons has a greater effect the prediction result of NAR neural network model. Therefore, we make full use of prior information to constrain and test when making predictions. We choose reasonable parameter settings to obtain more reliable prediction results. Three experiments are conducted to validate the high prediction accuracy of the NARMKM model, with mean absolute percentage error (MAPE), root mean square error (RMSE), STD and R2. These results demonstrate the superior fitting performance of the NARMKM model when compared to other six competitive models, including GM (1, 1), ARIMA, Multiple regression, FGM (1, 1), FANGBM and NAR. Our study provides a scientific basis and technical references for further research in the finance as well as population fields.
Multi-objective pedestrian tracking method based on YOLOv8 and improved DeepSORT
Authors: Sheng Wenshun , Shen Jiahui , Huang Qiming , Liu Zhixuan , Ding Zihao
Published: January 2024

A multi-objective pedestrian tracking method based on you only look once-v8 (YOLOv8) and the improved simple online and real time tracking with a deep association metric (DeepSORT) was proposed with the purpose of coping with the issues of local occlusion and ID dynamic transformation that frequently arise when tracking target pedestrians in real complex traffic scenarios. To begin with, in order to enhance the feature extraction network's capacity to learn target feature information in busy traffic situations, the detector implemented the YOLOv8 method with a high level of small-scale feature expression. In addition, the omni-scale network (OSNet) feature extraction network was then put on top of DeepSORT in order to accomplish real-time synchronized target tracking. This increases the effectiveness of picture edge recognition by dynamically fusing the collected feature information at various scales. Furthermore, a new adaptive forgetting smoothing Kalman filtering algorithm (FSA) was created to adapt to the nonlinear condition of the pedestrian trajectory in the traffic scene in order to address the issue of poor prediction attributed to the linear state equation of Kalman filtering once more. Afterward, the original intersection over union (IOU) association matching algorithm of DeepSORT was replaced by the complete-intersection over union (CIOU) association matching algorithm to fundamentally reduce the target pedestrians' omission and misdetection situation and to improve the accuracy of data matching. Eventually, the generalized trajectory feature extractor model (GFModel) was developed to tightly merge the local and global information through the average pooling operation in order to get precise tracking results and further decrease the impact of numerous disturbances on target tracking. The fusion algorithm of YOLOv8 and improved DeepSORT method based on OSNet, FSA and GFModel was named YOFGD. According to the experimental findings, YOFGD's ultimate accuracy can reach 77.9% and its speed can reach 55.8 frames per second (FPS), which is more than enough to fulfill the demands of real-world scenarios.
Numerical investigation of quantitative pulmonary pressure ratio in different degrees of stenosis
Authors: He Fan , Li Minru , Wang Xinyu , Hua Lu , Guo Tingting
Published: January 2024

Background

Pulmonary artery stenosis endangers people's health. Quantitative pulmonary pressure ratio (QPPR) is very important for clinicians to quickly diagnose diseases and develop treatment plans.

Objective

Our purpose of this paper is to investigate the effects of different degrees (50% and 80%) of pulmonary artery stenosis on QPPR.

Methods

An idealized model is established based on the normal size of human pulmonary artery. The hemodynamic governing equations are solved using fluid-structure interaction.

Results

The results show that the QPPR decreases with the increase of stenosis degree, and it is closely related to the pressure drop at both ends of stenosis. Blood flow velocity and wall shear stress are sensitive to the stenosis degree. When the degree of stenosis is 80%, the amplitude of changes of blood flow velocity and wall shear stress at both ends of stenosis is lower.

Conclusions

The results suggest that the degree of pulmonary artery stenosis has a significant impact on QPPR and hemodynamic changes. This study lays a theoretical foundation for further study of QPPR.

Published: January 2024

Liver rupture repair surgery serves as one tool to treat liver rupture, especially beneficial for cases of mild liver rupture hemorrhage. Liver rupture can catalyze critical conditions such as hemorrhage and shock. Surgical workflow recognition in liver rupture repair surgery videos presents a significant task aimed at reducing surgical mistakes and enhancing the quality of surgeries conducted by surgeons. A liver rupture repair simulation surgical dataset is proposed in this paper which consists of 45 videos collaboratively completed by nine surgeons. Furthermore, an end-to-end SA-RLNet, a self attention-based recurrent convolutional neural network, is introduced in this paper. The self-attention mechanism is used to automatically identify the importance of input features in various instances and associate the relationships between input features. The accuracy of the surgical phase classification of the SA-RLNet approach is 90.6%. The present study demonstrates that the SA-RLNet approach shows strong generalization capabilities on the dataset. SA-RLNet has proved to be advantageous in capturing subtle variations between surgical phases. The application of surgical workflow recognition has promising feasibility in liver rupture repair surgery.
Region fine-grained attention network for accurate bone age assessment
Authors: Deng Yamei , Song Ting , Wang Xu , Chen Yonglu , Huang Jianwei
Published: January 2024

Bone age assessment plays a vital role in monitoring the growth and development of adolescents. However, it is still challenging to obtain precise bone age from hand radiography due to these problems: 1) Hand bone varies greatly and is always masked by the background; 2) the hand bone radiographs with successive ages offer high similarity. To solve such issues, a region fine-grained attention network (RFGA-Net) was proposed for bone age assessment, where the region aware attention (RAA) module was developed to distinguish the skeletal regions from the background by modeling global spatial dependency; then the fine-grained feature attention (FFA) module was devised to identify similar bone radiographs by recognizing critical fine-grained feature regions. The experimental results demonstrate that the proposed RFGA-Net shows the best performance on the Radiological Society of North America (RSNA) pediatric bone dataset, achieving the mean absolute error (MAE) of 3.34 and the root mean square error (RMSE) of 4.02, respectively.
Study on mechanical and micro structural properties of spin arc welding in Hastelloy C-2000
Authors: Karthic Subramaniyan Ilavarasan , Kumaravel Srividhya Poosari , Kesavan Jothi
Published: January 2024

Nickel-based Hastelloy C-2000 is widely used in the aerospace, chemical, and medicinal sectors. Investigating the potential efficacy of the spin arc welding process on Hastelloy C-2000 was the main focus of this study. In spin arc welding the centrifugal force has been obtained in the fusion zone, thus the weldbead quality increases. Weld current, rotating speed, and spin diameter are all separate parameters used in the welding procedure. The microstructural investigation was carried out using optical microscopy, X-Ray Diffraction (XRD), and field emission scanning electron microscopy (FESEM). The mechanical characteristics of the welded specimens were examined closely. Spin Arc Welding ultimate tensile strength (UTS), hardness value (HV), and impact experiments were compared to those of the Multi-pass Pulsed Current Gas Tungsten Arc welding method (MPCGTAW). In 27 tests, increasing the current and rotating speed resulted in greater penetration depth and weld height. The width of the weld was found to be a little high, with a spinning diameter of 2 mm. In comparison, samples 5 and 15 were found to have better hardness, tensile strength, and toughness, especially with suitable welding parameters such as current (120 I and 140 I), speed (1800 rpm), and spin diameter (2 mm and 3 mm). A microstructural study showed no grain segregation, contributing to the material’s increased hardness and tensile strength. The novel findings of the present study suggest that spin arc welding might be superior for various Hastelloy C-2000 connections that might have great applications in industries.

Published: January 2024

Aluminium matrix composite (AMC) materials play an important role in the field of automobile and aerospace industries due to their excellent properties. In this research, aluminium alloy (AA7075) was reinforced with alumina (Al2O3) particles to improve their hardness and tribological behaviour of the base alloy. Four composites were prepared by varying the content (4, 8 and 12 wt.%) of Al2O3 particles through the stir casting technique. The surface morphology of the proposed composites ensured the uniform distribution of Al2O3 particles into the matrix alloy. The hardness of the composite was measured using a Brinell hardness tester and the maximum value of hardness was found in the AA7075 - 8 wt.% Al2O3 composite. Hence, a tribological investigation was carried out on this AA7075 - 8 wt.% Al2O3 composite. Load (P), sliding speed (V) and sliding velocity (D) were taken as the wear parameters for conducting the experiments. A Technique for Order Preference by Similarity to Ideal Preferred Solution (TOPSIS) approach has been applied to find out the optimal conditions of parameters to obtain the lowest wear rate (WR) and the co-efficient of friction (COF). The results showed that the lowest WR and COF was obtained at ‘P’ of 15 N, ‘V’ of 1 m•s-1 and ‘D’ of 1000 m•s-1. ANOVA results revealed that ‘P’ is the factor with the most significant contribution (38.36%), followed by ‘D’ (28.32%). The worn surface morphology of the confirmation experiment specimen was investigated by SEM and the wear mechanism was reported.

Published: January 2024

Epigenetic regulation plays a crucial role in the development and progression of cancer, including the regulation of antitumor immunity. The reversible nature of epigenetic modifications offers potential therapeutic avenues for cancer treatment. In particular, histone deacetylase (HDAC) inhibitors (HDACis) have been shown to promote antitumor T cell immunity by regulating myeloid cell types, enhancing tumor Ag presentation, and increasing expression of chemokines. HDACis are currently being evaluated to determine whether they can increase the response rate of immune checkpoint inhibitors in cancer patients. Although the potential direct effect of HDACis on T cells likely impacts antitumor immunity, little is known about how HDAC inhibition alters the transcriptomic profile of T cells. In this article, we show that two clinical-stage HDACis profoundly impact gene expression and signaling networks in CD8+ and CD4+ T cells. Specifically, HDACis promoted T cell effector function by enhancing expression of TNF-α and IFN-γ and increasing CD8+ T cell cytotoxicity. Consistently, in a murine tumor model, HDACis led to enrichment of CD8+ T cell subsets with high expression of effector molecules (Prf1, Ifng, Gzmk, and Grmb) but also molecules associated with T cell exhaustion (Tox, Pdcd1, Lag3, and Havcr2). HDACis further generated a tumor microenvironment dominated by myeloid cells with immune suppressive signatures. These results indicate that HDACis directly and favorably augment T cell effector function but also increase their exhaustion signal in the tumor microenvironment, which may add a layer of complexity for achieving clinical benefit in combination with immune checkpoint inhibitors.

Authors: Shin Dong Eun , Jung Yeseul , Ossak Grace Ndombi , Nam Eun Woo
Published: January 2024

Background: The COVID-19 outbreak caused the border closure, martial law declaration, and lockdown to prevent the spread of the disease. These policies caused reduced interaction among people, social isolation, and higher levels of anxiety and depression.
Objectives: This study aimed to examine changes in depressive symptoms of residents of the Democratic Republic of Congo (DRC) that may have arisen due to the COVID-19 and lockdown measures and to identify relevant influencing factors.
Methods: This cross-sectional study involved 300 residents of the DRC. An online survey tool investigated general and public health characteristics and included the Patient Health Questionnaire-9 for measuring depressive symptoms. The study was conducted from April 7–30, 2020.
Results: The average depression score was low at 2.74±3.33. Factors influencing depression were the number of family members, probability of death due to COVID-19, knowledge of COVID-19, and time at home. The factor that most significantly influenced depression and these variables accounted for 26.9% of the influence of COVID-19 on depression (F= 9.936, p<.001).
Conclusion: This study investigated the influence of COVID-19 outbreak on depression in DRC. Levels of depression increased for individuals who were living alone, had low levels of knowledge of COVID-19 and awareness of the disease severity, and spent a long time at home.

Published: January 2024

Tobacco and alcohol use during pregnancy has negative consequences for the fetus. The study's purpose was to investigate the practices of pregnant women regarding the use of tobacco and alcohol during pregnancy. A quantita‑ tive research approach with a descriptive, cross‑sectional, analytical design was used. The population was all pregnant women aged 18 years and above attending antenatal care at the Mariental clinic. Written informed consent was obtained from all respondents prior to data collection. Data was collected from 211 respondents selected through a systematic sampling. Data was analyzed using Statistical Package of the Social Sciences version 27. Descriptive statistics were used for frequencies and percentages. Fisher's Exact test at 0.05 alpha level was used to determine the association between variables. The mean age was 28.8, with a standard deviation of 6.9 years. Most participants, 92 (43.6%), were aged between 18 and 24 years. The majority, 186 (88.15%), were in the third trimester of pregnancy, and 154 (73%) were single. Most, 148 (70.14%), respondents have good practices towards alcohol use during pregnancy. Moreover, 190(90 %) of the respondents were classified as having good practices towards tobacco use in pregnancy. Educational levels showed a significant association with practices towards tobacco smoking (P=0.042). The study concluded good practices among pregnant women on alcohol and tobacco smoking during pregnancy. It is recommended that health facilities should introduce awareness campaigns on the dangers of alcohol and tobacco use during pregnancy. Moreover, educational materials should be developed in local languages and distributed to the community.
Development of non-public forms of education created and managed by citizens – summary of time perspectives
Authors: Berkowicz Aleksandra
Published: January 2024

In the Polish People’s Republic (PRL), almost all schools were state-owned and served a subservient role to the communist system. Non-public schools in Poland, which developed in the late 1980s, are either charter schools run by the NGOs or private schools run by the individuals. The development of non-public schools in Poland was a manifestation of a grassroots initiative of civil society, which did not approve of the totalitarian ideology implemented in public schools and the dysfunctional, backward way of managing these schools. The aim of the article is to present the dynamics of the development of non-public forms of education in Poland in the years 1989–2014. The study used quantitative methodology – statistical data obtained by information registers of public administration. The compilation of this data allowed to show the development dynamics of non-public schools in Poland and the development direction of this phenomenon. The analysis of the existing data made it possible to draw a specific map of the development of non-public schools according to the number of schools, students, and teachers, also taking into account the geographical distribution of these schools in individual Polish voivodships. The conclusions of the research confirm the thesis that the creation and development of private schools is a phenomenon that was a social work from the beginning – a bottom-up initiative of civil society. The article fills the research gap through a synthetic approach to the development of education alternatives to the public education in Poland, in which the responsibility for the partial task implementation of meeting needs and providing well for the students in the context of education was taken over by citizens instead of the state. It also aims at spreading awareness among scientists and society of the importance of the issues raised in the text, while inspiring the participation of citizens in social life and their specific impact, the strength of which results in the changes made on the surrounding reality.

Historia pojęcia „solidarność”
Authors: Koba Laura
Published: January 2024

Solidarity as a polysemous (ambiguous) concept is a multicultural or supra-cultural value rooted in ethics all over the world. It refers primarily to human community life and the universal tendency to support each other in dangerous situations, a tendency that is written in our genes. This concept is currently experiencing a renaissance, appearing in new areas of human life, e.g. in connection with the Covid-19 pandemic, climate disasters, the war in Ukraine; in scientific research; in new technologies (artificial intelligence); or in microbiology – where it is solidarity discovered in the natural world (e.g. the world of fungi), and thus also an introduction to the synonyms of solidarity and the concept of symbiosis. The concept of solidarity includes the obligation to care for those in need and the responsibility to continue living in the „global village“ as an expression of solidarity with future generations.

Review of Ahmed Fal Sbai’s The Authenticity Dilemma in the Arab Pragmatic Discourse:
Authors: SEMSADI MOHAMED SALEM
Published: January 2024

This book is a compelling contribution to modern criticism, and critical discourse analysis in particular. The book itself is a critique of the Arab pragmatic discourse, wherein A. F. Sbai (PhD.) lays great emphasis on wider developments and intervening factors, taking T. Abdel Rahman’s published works as a focal case for study to support his central implicit argument and intentions: the deconstruction of the entire Abdel Rahman-based discourse community and the introduction of his project of Islamic pragmatics. This review focuses mainly on the deconstructionism in action of primary sources, which is the critical approach Sbai adopts to arrive at his revolutionary findings successfully.
analysis of debt sustainability in Brazil
Authors: Ferreira-Filho Helder Lara
Published: January 2024

Resumo: Este artigo tem como objetivo discutir a sustentabilidade da dívida da economia brasileira, que está sob escrutínio desde 2013. As economias emergentes podem enfrentar instabilidade com balança de pagamentos ou aumento da inflação devido a uma possível desvalorização cambial. Assim, foram realizadas simulações prospetivas da dinâmica da dívida bruta utilizando dados disponíveis até 2023. Até 2040, sob as expectativas do mercado e certos pressupostos, a dívida bruta não parece explosiva. A Dívida Bruta do Governo Geral (DBGG) tende a aumentar no curto prazo, estabilizando-se no médio e longo prazo. Contudo, não é uma situação confortável, especialmente considerando que os níveis de DBGG estão acima dos países emergentes e dada a possibilidade de choques adversos nas variáveis ​​mais relevantes sobre a dinâmica da dívida. A combinação de “r – g” deve melhorar para que o Brasil tenha uma trajetória de dívida mais benigna.

Abstract: This article aims to discuss the debt sustainability for the Brazilian economy, which has been under scrutiny since 2013. Emerging economies may face instability with balance of payments or rising inflation due to a possible currency devaluation. Thus, prospective simulations of gross debt dynamics were conducted using data available up to 2023. Until 2040, under market expectations and certain assumptions, gross debt does not seem explosive. General Government Gross Debt (GGGD) tends to rise in the short term, stabilizing in the medium and long term. However, it is not a comfortable situation, especially considering that GGGD levels are above those of emerging countries and given the possibility of adverse shocks in the most relevant variables regarding debt dynamics. The combination of “r – g” should improve for Brazil to have a more benign debt trajectory.

This study examined and measured the effectiveness of a flipped classroom method on the performance of Grade 10 learners in mathematics at Liceo de Los Baños. Quantitative research methodology, namely Quasi Experimental Research Design, is used in this study. To discover or choose respondents, match pairing techniques were used. There were two groups of students in this study: the experimental group and the comparison group. The students in the experimental group were exposed to a flipped classroom technique in which they were given an advanced video lecture with guided activities and self-activity on the day of their lesson. Students in the comparative group were exposed to the traditional approach. The study's main findings were evident. It was found out that the pretest mean score of the experimental group and comparison group were the same. The experimental group received higher points in their posttest after gathering all the relevant data. As a result, a considerable distinction between two groups was discovered. The findings revealed that learners who had prior knowledge because of a video lecture or a flipped classroom technique were more likely to improve their mathematical and logical skills. The researcher recommended using this strategy to enhance students’ ability in terms of mathematical and logical skill. Furthermore, future researchers should improve their video lesson to make it more appealing to learners to capture their attention.

Sufficient financing in local government institutions is the key to effectively carry out a wide range of functions at the local level. In Bangladesh, municipalities play a pivotal role in delivering various services and engaging in socio-economic activities. This research aims to assess the financial conditions of urban local government organizations in Bangladesh, with a particular emphasis on Gangni Pourashava in Meherpur District. The study adopts a comprehensive approach, combining qualitative and quantitative methods, including a structured questionnaire survey and interviews for data collection. The findings reveal that local governments exhibit favorable financial conditions to cover their expenditures. However, a stark contrast emerges when considering citizen satisfaction, with widespread dissatisfaction attributed to the perceived lack of financial responsibility, citizen participation, and transparency. Notably, the research identifies several key challenges, including the absence of financial autonomy, dependence on government grants, and resource constraints. These findings suggest that municipalities need to engage in comprehensive financial planning that is transparent and involves greater citizen participation.

Authors: Arcenio Cláudia Rodrigues do Carmo , Azevedo Patricia Bastos de
Published: January 2024

Resumo: O presente artigo busca discutir os sentidos da alfabetização e do letramento que circundam os programas federais de formação continuada de professores alfabetizadores desenvolvidos entre 1990 e 2020. Trabalhamos com a hipótese de que esses programas podem se estabelecer como indícios de quais usos políticos a leitura e a escrita assumiram durante o período investigado, bem como refletem os atravessamentos políticos educacionais e ideológicos que permeiam a alfabetização brasileira. Na análise dos materiais elaborados para o desenvolvimento desses programas observamos incoerências entre os significados de alfabetização e do que significa estar alfabetizado ao longo desses trinta anos. O texto apresenta uma ficha técnica dessas formações e explicita os conceitos de alfabetização expressos textualmente em seus materiais buscando trazer apontamentos que podem contribuir para as discussões na área da alfabetização e da formação de professores.

Long distance relationship (LDR) is a form of romantic relationship where two people are separated by physical distance which makes it difficult for both to establish closeness within a certain period. Of course, living in a long-distance relationship is not an easy thing if there is no self-disclosure and interpersonal trust in the relationship. Openness is one of the factors that play an important role in forming interpersonal trust.  Openness arises because of the trust between partners and this encourages them to feel comfortable in sharing all kinds of information about themselves to their partners. The purpose of this study is to determine the relationship between self-disclosure and interpersonal trust in early adult couples who undergo long-distance relationships. This study uses a correlational quantitative approach with 120 respondents. The sampling technique in this study used accidental sampling. The results of the correlation coefficient analysis obtained are 0.837 and the significance value of the correlation r is 0.000 (p <0.05). The effective contribution between self-disclosure and interpersonal trust is 70%. So it can be concluded that there is a positive relationship between self-disclosure and interpersonal trust, meaning that the higher the self-disclosure, the higher the level of interpersonal trust in early adult couples who undergo long-distance relationships, and vice versa
