Authors: Aktaş Hayri , Güneş Gencer Gökçe Yağmur
Published: October 2024

Aims: Cognitive function in older adults has been a topic of growing interest in recent years. This study aimed to investigate the relationship between cognitive function and physical activity, functional status, and social participation in older adults.
Methods: A cross-sectional study was conducted involving 123 older adults aged 65 years and older who met the study’s inclusion criteria. The inclusion criteria for the study were as follows: who were aged 65 years or older, literate, volunteering to participate in the study, had no hearing or vision defects that prevented the measurement of the scales used in the study, had no chronic disease that prevented the scales used in the study. The data in the study were collected with sociodemographic form, Montreal cognitive assessment, international physical activity questionnaire, timed-up-and-go test, 10-meter walk test, and Keele assessment of participation.
Results: The average age of the participants was 69.5±4.6. The study included 46.3% women and, 57.7% primary school graduates. A positive and moderate relationship was found between cognitive functions and physical activity level, functional status, and social participation in older adults. Additionally, there was a moderate positive relationship found between the level of physical activity, functional status, and social participation. In the cognitive function risk model, it was found that age, education level, and social participation significantly impact cognitive functions in older adults.
Conclusion: Increasing physical activity, functionality, and especially social participation in older adults can be considered an important intervention to protect and improve the cognitive functions of older adults.
Particle Entanglement With the Observer’s Polarized Dual Consciousness — A Modified Stern Gerlach Experiment, as Proof
Authors: Pletcher Arthur
Published: October 2024

Post-corpus callosotomy (split brain surgery) patients, have demonstrated that there exists two opposing minds within the single observer, which engage in a dynamic sequence of recursive information exchange, and ultimately collapse to one single polarized conscious state. it is therefore reasonable to hypothesize that particle observation also involves two opposing minds, which engage in a dynamic sequence of recursive information exchange, and ultimately collapse to one single polarized state, which then becomes entangled (in correspondence) with the observed particle. Subsequently becoming entangled with the local environment. Section \ref{sec-2s} shows how this sequence explains the logical inconsistencies of the two states experiments. A SIMPLE MODIFIED STERN GERLACH EXPERIMENTAL IS PROPOSED AS A PROOF.

This novel theoretical concept of a DIALECTIC DUAL OBSERVATION is mathematically modeled with the resulting decreasing Shannon entropy, increasing potential energy, Jarzynski equality and random information exchange probability. The mathematical conjecture is compared with Von Neuman entropy during Quantum Entanglement and collapse.
Culture: A factor of Political Life in Arab Islamic Societies
Authors: Blehová Irena
Published: October 2024

Any study of society, including an analysis of politics and international relations, must pay due attention to all factors. Culture, of course, is one of the fundamental determinants of any social life. Full comprehension of the internal organisation, links, inner processes and behaviour of a community or any of its members to other communities and international actors is impossible without the knowledge and understanding of its culture. This essay explores some typical features of Arab Islamic culture systems which help to explain some of what we encounter in today's Middle East: suicide bombings by Islamic radicals, spurts of violence, intransigence in negotiations, unwillingness to reach a compromise, etc. The author concentrates on some of the traditional values of Arab and Islamic societies and on Islam as the dominant religion in the region.

Roof Tile Printing Machines are important equipment in the industry for printing roof tiles and managing the roof tile production process. This tile printing machine includes a press machine and conveyor that can be adjusted so that the system can operate optimally during production. Operating a tile printing machine requires a program that can control various machine functions, such as conveyor motors and pneumatic cylinders. These programs are generally implemented using a Programmable Logic Controller (PLC). Therefore, an automatic tile printing system based on PLC and HMI with pressure and current parameters was created. This system can control and monitor the tile printing system while operating via the HMI screen. This method is used to collect data related to working methods, diagrams, cable connections, PLC programs, and data management in the HMI. One method used involves components such as limit switches, pressure sensors, current sensors, and pneumatics. The data generated from these processes is processed in the PLC and displayed on the HMI screen. The results obtained from this system are capable of monitoring the tile printing process in real time via the HMI screen.
Analisis Kemampuan Berpikir Kritis Matematis menggunakan Pendekatan Blended Learning pada Siswa Kelas VIIB Di SMP Negeri 6 Lembor
Authors: Jangko Laurensius , Yuwono Timbul
Published: October 2024

The background to this research is based on observations of students at SMP Negeri 6 Lembor, East Nusa Tenggara, where mathematical critical thingking abilities were still low. Data collection techniques include test results, interviews, and documentation. This data collection used critical thingking ability tests and interviews with twenty students from class 7B, even during the semester of the 2021/2022 academic year. Data analysis techniques use data reduction, data presentation, and concluding students' critical thinking skills in solving mathematical problems using the Blended Learning approach. The results showed that students with critical thinking skills in the 'low' category were only able to fulfill one indicator and did not fulfill all of them because they had not been able to understand the meaning of the problem, formulate concepts, write solutions, and draw conclusions properly and correctly. Students with 'medium' critical thinking skills can meet 2 to 3 indicators because they can only choose the right solution strategy but are still wrong and make mistakes in their calculations. In contrast, students with 'high' critical thinking skills meet all ability indicators—critical thinking. Because students can choose a solution strategy and give reasons related to the chosen strategy wholly and correctly, it can be concluded that as many as 80% can think critically in the 'low' category, as much as 10% can think critically in the 'medium' category, and 10% can think critically in the 'high' category.

Published: October 2024

This study focuses on using different cognitive styles to solve mathematical issues. Their cognitive styles can be observed when students work on mathematical problems involving mathematical representation skills. Furthermore, the analyst should assess the mathematical representation abilities of pupils at MTsN 1 Banda Aceh using the field-dependent (FD) and Field Independent (FI) cognitive styles. A descriptive, qualitative technique is used. This study employs purposive sampling procedures and focuses on two pupils from class VIII-2, one identified as FD and the other as FI. Instruments utilized include representation skill tests, interview guidelines, and GEFT questions. Analyzing the research data involves data reduction, presentation, triangulation, and conclusion formulation. The research findings point to many conclusions: (1) FI students find it easier to understand issues, can provide better conceptual explanations, solve problems faster, and explain their solutions accurately. (2) FD students have more difficulty solving issues because they rely on teacher directions. Additional concerns include their failure to analyze and comprehend information and retain concepts from challenges effectively. It is envisaged that students will understand their cognitive types to improve their mathematical representation skills in math and other courses.

This research aims to identify and analyze students' critical thinking skills and learning barriers in learning mathematics translation material. The concept of translation is fundamental for students who want to master geometric transformations. Students must understand the basics of translation because this understanding of translation will be needed at a higher level. However, many students still experience obstacles in understanding translation material. Students experience learning impediments because of the difference between the expected achievements of critical thinking skill indicators, interpretation, analysis, evaluation, and inference, and the actual results. This research uses a qualitative descriptive research methodology, utilizing data collection techniques such as interviews, observation, and documentation. Data analysis was conducted using descriptive methods with 30 class XI-1 students as participants. Triangulation was used in the data collection process, which involved using teacher and student interviews, administering diagnostic tests, and textbook analysis (document analysis). The research results show that the average percentage of students' critical thinking abilities from the four indicators is 41.665%. Ontogenic, didactic, and epistemological barriers cause the low critical thinking skills of class XI-1 in studying translation. The research results can be used as considerations for teachers in designing learning to improve critical thinking skills and reduce students' learning barriers in learning translational material.

Термический отжиг радиационно-индуцированного оптического поглощения кристаллов BaF2 и CaF2 облученных быстрыми ионами ксенона
Authors: Aralbayeva Gulnara
Published: October 2024

Кристаллы BaF2 и СaF2, обладающие высокой радиационной стойкостью и как сцинтилляторы с высоким временным разрешением, используются в физике высоких энергий. В настоящей работе исследуются радиационные дефекты в кристаллах BaF2 и CaF2 при облучении ионами 132Xe с энергиями 220 и 230 МэВ, соответственно, до флюенсов 1011-1014 ион/см2. Спектры радиационно-наведенного оптического поглощения измерялись в интервале от 1,5 до 10 эВ. Термический отжиг радационных дефектов, индуцированных в монокристаллах BaF₂ и CaF₂, изучался путем проведения пошагового отжига. Циклы "нагрев-охлаждение-измерение" выполнялись в идентичных условиях с увеличением температуры отжига (Tотж) на 20–30 К. Все спектры измерялись при комнатной температуре. Предполагается, что в радиационно-индуцированную полосу поглощения при 9,7 эВ в СaF2 имеют суммарный вклад анионные кластеры, созданные в области ионного трека, и сложные комплексные дырочные агрегаты. Центр, отвечающий за полосу с максимумом 8,15 эВ также имеет дырочную природу и структуру близкую к центру 6,5 эВ.  В УФ области спектра BaF2 наблюдается небольшое увеличение полосы 9,18 эВ в интервале температур 450-575К, которое сопровождается уменьшением полос с максимумами 6,5 и 8.2 эВ, то есть последняя также имеет дырочную природу. Полосы 7,4 эВ, 2,24 эВ и 3, 04 эВ практически не изменяются во всем интервале температур отжига. По аналогии с CaF2, в Xe-облученных монокристаллах BaF2 высокоэнергетические полосы ниже фундаментального поглощения также могут иметь природу анионных кластеров.

Magyarországon – a szomszédunkban zajló orosz–ukrán, illetve a gázai háború ellenére – az improvizált robbanóeszközök (IED-k) most kevésbé vannak reflektorfényben, mint korábban az afganisztáni és iraki szövetséges megszállás alatt voltak, de ezek továbbra is veszélyes fegyverek. A világ távolabbi részein zajló fegyveres összecsapásokban és az említett két konfliktusban is alkalmazzák őket. Mivel valószínűleg a belátható jövőben is veszélyt jelentenek mind a haderőkre, mind a civil lakosságra, a védekezés ellenük továbbra is kulcsfontosságú. Ez az írás az IED egyik fajtája, a rádió-távvezérelt eszközök elleni védekezés módszereit és lehetőségeit mutatja be.

Published: October 2024

Industrial pollution is a significant concern in Patna City, with rapid urbanization and industrial growth contributing to the degradation of natural resources. This study focuses on the physico-chemical analysis of industrial effluents and their effects on the water and soil quality in and around Patna. Effluents from various industries, including textile, sugar, rice mills, and small-scale manufacturing units, are released into nearby water bodies and soils, posing serious environmental risks. The research aims to assess the levels of pollutants by analysing key physico-chemical parameters such as pH, total dissolved solids (TDS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), heavy metals (lead, chromium, cadmium), and organic contaminants in industrial effluents. Samples were collected from various locations near industrial zones and water bodies. The study also evaluated the impact of these pollutants on soil and groundwater quality. It was found that prolonged exposure to industrial effluents led to the accumulation of toxic metals in soil, reducing its fertility and altering its structure. Additionally, groundwater sources were contaminated with hazardous chemicals, making them unfit for drinking and irrigation purposes. The implementation of advanced treatment technologies and sustainable industrial practices is crucial for safeguarding the environment and public health in Patna City.

ISLAMIC FAMILY LAW ON POLYGAMOUS MARRIAGE IN MALAYSIA: BETWEEN ROSES AND THORNS
Authors: Md Salleh Anis Shuhaiza , Abdul Jalil Najah Inani , Md Nasir Nor Ashikin , Awang Syahmi
Published: October 2024

Marriage is a way of gaining a peaceful mind and soul, be it monogamous or polygamous marriage. This is the sweetness of marriage as enshrined by Islam. To achieve this wisdom, conditions laid down by the religion and legal requirements must be observed. Otherwise, a marriage may turn into a miserable and thorny life for couples, especially in polygamy. Thus, the purpose of this paper is to disseminate legal knowledge and refine the understanding about polygamous law in Malaysia. The central arguments of this study are two-pronged: (1) to deliberate on the Malaysian legal framework for polygamous marriage and (2) to discuss a crucial legal issue related to polygamy, namely cross-border marriage and its effects. The qualitative method of doctrinal legal research was employed to obtain and analyse primary and secondary data from various sources. It included examining the statutes and decided cases of the Syariah Courts, including reported and unreported cases. The relevant statutes studied were the Islamic Family Law (Federal Territories) Act 1984 and the Enactment of Islamic Family Law (Kedah Darul Aman) 2008. In substantiating arguments, data from e-Syariah Version 3 (ESV3) was used together with existing literature. The findings revealed that refusal or failure to comply with legal requirements pertaining to polygamous marriage may lead to cross-border marriage and its aftermath effects on the legality of the marriage, jurisdiction of the court, and the rights of wives and children in the context of law. Hence, the enforcement of existing laws on polygamy should be emphasised to control any abuse of power by a man to contract a polygamous marriage. More importantly, the laws and enforcement should be strengthened to protect the rights of the wives and children. Future research may focus on issues involving the rights of the wives and children of a polygamous marriage upon the death of the husband or father according to Islamic family law in Malaysia and its implementation.

Functional Analysis of Hif1 Histone Chaperone in Saccharomyces cerevisiae
Authors: Dannah Nora S. , Nabeel-Shah Syed , Kurat Christoph F. , Sabatinos Sarah , Fillingham Jeffrey
Published: October 2024

The Hif1 protein in the yeast Saccharomyces cerevisie is an evolutionarily conserved H3/H4-specific chaperone and a subunit of the nuclear Hat1 complex that catalyzes the acetylation of newly synthesized histone H4. Hif1, as well as its human homolog NASP, has been implicated in an array of chromatin-related processes including histone H3/H4 transport, chromatin assembly and DNA repair. In this study, we elucidate the functional aspects of Hif1. Initially we establish the wide distribution of Hif1 homologs with an evolutionarily conserved pattern of four tetratricopeptide repeats (TPR) motifs throughout the major fungal lineages and beyond. Subsequently, through targeted mutational analysis, we demonstrate that the acidic region that interrupts the TPR2 is essential for Hif1 physical interactions with the Hat1/Hat2-complex, Asf1, and with histones H3/H4. Furthermore, we provide evidence for the involvement of Hif1 in regulation of histone metabolism by showing that cells lacking Hif1 are both sensitive to histone H3 over expression, as well as synthetic lethal with a deletion of histone mRNA regulator LSM1. We also show that a basic patch present at the extreme C-terminus of Hif1 is essential for its proper nuclear localization. Finally, we describe a physical interaction with a transcriptional regulatory protein Spt2, possibly linking Hif1 and the Hat1 complex to transcription-associated chromatin reassembly. Taken together, our results provide novel mechanistic insights into Hif1 functions and establish it as an important protein in chromatin-associated processes.
Reports on boys’, youth’s and men’s health in Canadian newspapers: Now what?
Authors: Zanchetta Margareth , Byam Aaron Andrew , Solomon Donna , Jalili Katayoon , Haag Carlos , Tallarico Silvia
Published: October 2024

Background: This media content analysis explored the Canadian newspapers reporting on men's health, and their contribution to public understanding of the social determinants of men’s health and lifestyles.

Methods: A media content analysis of 44 news articles on boys’, youth’s and men’s health,published from 2010 to 2014 by three national newspapers (The Globe and Mail, National Post,and Metro News).

Results: Data indicated that the predominant discourse consists of informative and awareness messages, mostly about men’s prostate and sexual health. Very little health news content referred to working conditions, education and income, all of which are significant social determinants of health (SDH). This may reflect the current state of health research, which does not adequately incorporate the effects of these determinants. It may also indicate a reproduction of dominant health knowledge and understanding of masculinity. Little content was found on policy solutions to other publicized health issues, such as limited access to health services or inter-sectoral collaborations; this reflects a lack of government action and a lack of citizen engagement toward the creation of a concerted men’s health policy.

Conclusion: Despite the acknowledged importance of the media in promoting access to health information and indirectly contributing to improve the general public’s level of health literacy, it is also necessary to remember that there must be a greater attention to the structural constraints imposed by socioeconomic inequalities. Future studies should explore media discourses about men’s unequal access to health care services and citizens’ awareness of ways to overcome those inequalities shortcomings.

Authors:   The Korean Production And Operations Management Society, Gwon Hyejeong , Lee Namkyung
Published: October 2024

Online gift-giving market has been experiencing unprecedented growth, along with the development of the platform industry and the rise non-face-to-face transactions after COVID-19. The domestic online gift-giving market has developed with the launch of the Kakaotalk gift- giving service. As competition has intensified in recent years as various online retailers have added the gift-giving function, it is very important for the growth of a company to understand which variables affect gift satisfaction and repurchase behavioral intentions. In this study, we analyzed how individual disposition and gift-giving motivation affect gift satisfaction and behavioral intention. The regulatory focus theory was applied to measure the individual's disposition, and the gift-giving motivation which is important variable in gift-giving situation was divided into voluntary and obligatory cases. As a result of multivariate analysis of variance (MANOVA), when the gift- giving motivation is voluntary, it has a positive effect on gift satisfaction and the interaction effect of the regulatory focus and gift-giving motivation on gift satisfaction and behavioral intention was found.

Published: October 2024

Acute retinal necrosis (ARN) is a profound infection of the retina, marked by acute panuveitis, retinal periarteritis, and widespread necrotizing retinitis. The etiology of ARN involves human herpesviruses, such as herpes simplex virus (HSV) and varicella-zoster virus (VZV), which can lead to severe visual impairment or even blindness. A diagnosis of ARN is based on clinical characteristics and disease progression according to the standard diagnostic criteria established by the American Uveitis Society (AUS) in 1994. The polymerase chain reaction(PCR) of aqueous specimens can enable identification of the type of virus. Early initiation of antiviral medication is essential for treatment efficacy to stop lesion progression, accelerate the healing process, and prevent contralateral eye involvement. Ocular complications of ARN include atrophic retina, multiple retinal breaks, rhegmatogenous retinal detachment (RRD), tractional retinal detachment (TRD), optic atrophy, macular edema, epiretinal membrane (ERM), and retinal and optic disc neovascularization. This review summarizes the clinical features, diagnostic criteria, and recently recommended ARN management.

Background/Aims: This study aimed to identify the risk factors for chronic kidney disease (CKD) and end-stage renal disease (ESRD) following liver transplantation (LT), with a specific focus on tacrolimus levels and intrapatient variability (IPV).Methods: Among the 1,076 patients who underwent LT between 2000 and 2018, 952 were included in the analysis. The tacrolimus doses and levels were recorded every 3 months, and the IPV was calculated using the coefficient of variability. The cumulative incidence rates of CKD and ESRD were calculated based on baseline kidney function at the time of LT. The impact of tacrolimus levels and their IPV on the development of CKD and ESRD was evaluated, and the significant risk factors were identified.Results: Within a median follow-up of 97.3 months, the 5-year cumulative incidence rates of CKD (0.58 vs. 0.24) and ESRD (0.07 vs. 0.01) were significantly higher in the acute kidney injury group than in the normal glomerular filtration rate (GFR) group. In the normal GFR group, the tacrolimus levels were identified as a risk factor for CKD, with a level of ≤4.5 ng/mL suggested as optimal for minimizing the risk of CKD. Furthermore, the IPV of tacrolimus levels and doses emerged as a significant risk factor for CKD development in both groups (p<0.05), with tenofovir disoproxil fumarate also being a risk factor in HBV-infected patients. The IPV of tacrolimus levels was also a significant factor in ESRD development (p<0.05).Conclusions: This study elucidated the optimal tacrolimus trough level and highlighted the impact of IPV on the CKD and ESRD development post-LT.

World Health Organization recommends exclusive breastfeeding for six months. Despite its well- documented benefits, breastfeeding rates worldwide do not meet the recommended goals. The aim of this study was to identify factors that could influence exclusive breastfeeding at hospital discharge. All live, singleton, term births in a private hospital of Athens, Greece between January and December 2019 were included with a final study sample of 7336 women and newborns. Our study identifies several factors associated with nonexclusive breastfeeding ta hospital discharge: nullipara women compared to multipara (OR 0.73; 95% CI 0.66, 0.82), cesarean delivery compared to vaginal delivery (OR 1.83; 95% CI 1.65, 2.03), smoking during pregnancy (OR 1.28; 95% CI 1.15, 1.44), gestational age at 37+0- 38+6 weeks compared to 39+0- 41+6 weeks (OR 0.70; 95% CI 0.62, 0.78), birthweight <2500g (OR 0.38; 95% CI 0.22, 0.35), and admission to neonatal intensive unit (NICU) after delivery (OR 8.19; 95% CI 6.65, 10.08). No association was observed for maternal age, pregnancy after assisted reproductive technology, gestational diabetes, obstetric complication, and sex of the newborn. It is expected that our results will allow future comparisons between different hospitals in the same country, as well as comparison of practices with other countries. Several perinatal factors related to nonexclusive breastfeeding at hospital discharge, most noteworthy were caesarean section and admission to NICU.
Case report: A Large Fibroepithelial Polyp of the Vulva

Published: October 2024

Fibroepithelial polyps are one of the most common benign masses of the vulva and are characterized by relatively small size, vague symptomatology, and morphological diversity. These lesions mainly affect women of reproductive age and are hormone dependent. They are usually found around the urogenital area. A biopsy and histological examination are necessary to exclude the possibility of malignant neoplasm. The pathophysiology of the disease appears to be associated with the coexistence of diabetes mellitus, chronic inflammation and chronic friction. Below we will describe the case of a 17-year-old Somali patient who had undergone female genital mutilation type IIb tyand who presented to the regular clinic with a reported unspecified vulvar mass with coexisting chronic lower limb lymphedema.

Espacios Compactos
Authors: Criado Regino , Flores Álvarez Julio
Published: October 2024

En este tema, propio de un curso de introducción (de un cuatrimestre de duración) a la Topología General, vamos estudiar algunas propiedades de los espacios topol\'ogicos compactos, ciertas caracterizaciones que aparecen si se dan ciertas condiciones adicionales, así como (fundamental) su comportamiento con respecto a las funciones continuas definidas en ellos (en particular las funciones continuas que tienen codominio $\mathbb{R}$, para las que la compacidad garantiza la existencia de extremos, es decir puntos en los que dichas funciones alcanzan sus valores máximo y mínimo). La compacidad es un concepto fundamental en topolog\'ia pues tiene muchas propiedades muy \'utiles. Por ejemplo, si un conjunto está sumergido en $\mathbb{R}$ o $\mathbb{R}^n$, entonces la propiedad de ser compacto es equivalente a la de ser un conjunto cerrado y acotado, es decir, un conjunto que contiene a todos sus puntos l\'imite y tal que todos sus puntos están a una distancia finita entre sí. Otra propiedad llamativa es que un conjunto compacto en un espacio $T_2$ se comporta como un punto. Finalmente señalaremos que, aunque la definición más operativa es la de que un espacio topol\'ogico es compacto si y s\'olo si todo recubrimiento abierto del espacio tiene un subrecubrimiento finito, resulta intuitivamente m\'as clara la que resulta de pasar al complementario: Un espacio topológico es compacto si y sólo si cualquier colección de conjuntos cerrados $\{C_i\}_{i \in I}$ del mismo tal que $\cap _{i \in I}C_i=\emptyset$, posee una subcolección finita cuya intersección es también $\emptyset$}

A pump’s impeller could become eccentric relative to its casing and this geometric eccentricity can generate rotordynamic forces. However, studies of this problem in mixed-flow pumps are scarce. In this study, a complete mixedflow pump system, which includes a suction pipe, shrouded impeller, diffuser, and discharge volute, has been investigated using three-dimensional steady Reynolds-averaged Navier-Stokes (RANS) simulations. RANS simulation results with a concentric impeller (Model C) have been validated against experimental data. Two eccentric models - one with eccentric seal and concentric impeller and (Model 1) and another with both eccentric seal and eccentric impeller (Model 2)–have been simulated. Numerical results show that geometric eccentricity leads to a non-axisymmetric pressure distribution inside the seal cavity. For Model 1, the direct force is positive, and its magnitude is approximately 2.5 times larger than that of the cross force. For Model 2, direct stiffness force is also positive, but its magnitude is approximately 6 times larger than that of cross stiffness force. Thus, the direct force of Model 2 is approximately 30% higher than that of Model 1. This difference between the two eccentric models is likely due to the upstream inlet flow redistribution in the tangential direction as well as non-axisymmetric impeller torque in Model 2. Therefore, it is important to consider non-axisymmetric primary flow path as well as non-axisymmetric secondary flow path for rotordynamic analysis of mixed-flow pumps.

The CFD solver based on the Reynolds averaged stress (RANS) equation remains the main tool for aerodynamic analysis of turbomachinery at present. In order to minimize manual intervention in numerical simulation, the RANS solver needs to have good convergence and robustness. A fast implicit Jacobian-Free Newton-Krylov finite volume method has been developed for steady-state simulation of turbomachinery based on multi-block structure mesh. Based on the generalized residual minimization (GMRES) method, a matrix free solution for large-scale linear sparse systems was implemented, which avoids expensive and complex explicitly assembly of high-order Jacobian matrices. To reduce the difficulty of solving linear systems, a low order Jacobian matrix assembled by graph coloring and finite difference method is adopted to precondition the linear system. In nonlinear iteration, globalization strategy is applied to update the flow solution, improving convergence efficiency and robustness. The approximate Jacobian matrix is used for iterative calculation in the initial calculation to obtain sufficiently accurate flow field linearization, and then switched to Newton iterative method to achieve the goal of nonlinear convergence. Finally, some classic cases were used to verify the accuracy and robustness of the simulation.
