Published: August 2023

Although breast cancer is one of the types of cancer that most affects and kills women in Brazil, there is still a deficit in the early screening of this pathology associated with limited literacy in women's health. This study aims to evaluate the health literacy (HL) of women concerning breast cancer. Data were obtained through interviews with patients between 50 and 69 years old, using a semi-structured socioeconomic questionnaire and an LS assessment instrument, and a review of the scientific literature. 83 women were interviewed who indicated that inadequate SL is associated with older age, more children, lower individual monthly income and lower education level, compared to women with adequate SL. Thus, a high rate of inadequate SL was evidenced in women of age for early detection of breast cancer, associated with conditions of social inequality.

Published: August 2023

Athletes who compete may be subjected to urine doping tests after each competition, training session, or at other occasions. Despite the restrictions and penalties, doping still manages to contaminate sports. Africans still have misgivings about anti-doping measures since they believe they were excluded from the regulatory process. The study's goal was to obtain empirical evidence on Nigerian athletes' attitudes toward urine doping prevention, influenced by; athletes' cultural, environmental, and emotional peculiarities. Participants included, 165(21.4 years, ± 2.1) athletes from 10 sports. Participation was voluntary. Mixed methods of quantitative and in-depth interviews were used to collect data. Descriptive statistics and testing for differences between categorical variables were calculated using a 2×2 table, chi2 and gamma tests. Findings indicated that; athletes voluntarily submitted to testing, with statistical significance for testing frequency (0.004) and age (0.022), but not for gender difference (0.66). Common themes in athletes' feedback were that their cultural norms were violated, confidentiality, presence of an atmosphere of bias that could damage test results, and conventional doping tests causing psychological pain, suffering and shame. It was concluded that the peculiarity of athletes should be considered when developing global legislation.
Making Sense of Malebranche's Occasionalist Argument for Living Morally
Authors: Taylor Mark
Published: August 2023

In two places, Nicolas Malebranche makes a strange moral argument that he presents as an advantage of his occasionalist metaphysics. Because God is the only true cause, every choice of sin can only be given causality by God's power. Every sinner, therefore, profanely forces God to serve sin; to avoid such sacrelige, the occasionalist has extra reason to avoid sin. My analysis of Malebranche's reasoning shows how this initially perplexing argument does indeed work and, in fact, provides a useful example of how several distinct pieces of his philosophical theology come together to form a surprisingly cohesive argument.

Published: August 2023

Background Racial and ethnically diverse communities have higher mortality rates from chronic diseases. One approach to address health disparities and systemic racism in health care is through alterations in primary care workforce development via the One-Minute Preceptor (OMP) Teaching Method. The University of North Carolina at Chapel Hill created a modified OMP Model for Health Equity to address racial health disparities while teaching. This quality improvement (QI) project focuses on faculty confidence in discussing racial health disparities with learners using the modified OMP Model. Methods The QI project used a Plan-Do-Study-Act (PDSA) framework. Faculty participated in the Awareness, Reflection/Empowerment, and Action (AREA) survey, to assess level of engagement in addressing health disparities. Family Medicine (FM) residents completed a survey on current precepting practices of ethno-racial health disparities. Faculty were introduced to the modified OMP, followed by a two-month intervention period. Post-intervention surveys assessed the impact and identified faculty development opportunities. The intervention took place within a Family Medicine Residency Program, specifically during outpatient continuity clinics and the inpatient Family Medicine Hospital Service. Results Faculty engagement increased in areas of awareness and action and decreased in reflection/empowerment. Residents reported higher satisfaction with Ethno-Racial health disparities clinical teaching after the intervention. Qualitative data suggests discussions are not occurring as often as residents desire and depend on different factors; race/ethnicity of the patient, clinical situation, social determinants of health impacting care, time, and preceptor. Discussion The modified OMP for Health Equity intervention can be used to increase awareness and promote self-reflection and change. Conclusion The PDSA cycle framework for an intervention can improve faculty engagement addressing Ethnic-Racial health disparities.

Authors: Hama Salh Hozan Jaza , Aziz Tavga Ahmed , Ahmed Zheen Aorahman , Aziz Dlivan Fattah
Published: August 2023

Objective: To investigate the dose-response relationship of the free radical-scavenging activities of boron and vitamin C in nitrite-induced hemoglobin oxidation in vitro and in vivo. Method: Different concentrations of boron and vitamin C were added to a hemolysate challenged with nitrite to induce methemoglobinemia (MetHb), and the most effective dose of boron and vitamin C was used before and after different intervals of inducing Hb oxidation, and the production of MetHb was monitored using a spectrophotometer. The effective doses of boron and vitamin C, alone and in combination, were administered to rats before challenging them with an oral dose of 100 mg/kg sodium nitrite. Results: In vitro results indicated that different concentrations of boron and vitamin C attenuated MetHb formation, with the maximum effect achieved at 0.08mg/L and 10mg/L, respectively. Moreover, when these doses were used at different time intervals, a maximum effect was achieved when added 10 min before nitrite. The in vivo results demonstrated a significant reduction in methemoglobin formation in rats treated with boron and vitamin C alone. The hematological markers were not changed except for the platelet levels, which increased in the boron-treated and combination groups. The monocyte-to-lymphocyte ratio decreased significantly in all treatment groups compared with the positive control group. Conclusion: Boron protects against Hb oxidation induced by nitrite, and a potentiated effect has been achieved with the combination of vitamin C.

Authors:   Management Faculty, AGH University of Science and Technology, 30-067 Kraków, Poland, Richert Maria
Published: August 2023

The work presents selected material issues related to the development of modern motorization. The advantages and threats of obtaining key materials for the automotive industry were analyzed. Aspiration to radically reduce CO2 emissions sets the main trend in the automotive industry focused on the production of electric cars. The production of electric cars is closely related to the development of innovative battery production technologies using such critical elements as lithium, magnesium, nickel, cobalt, and graphite. Their acquisition and production of components is concentrated in several countries around the world, including China, which is their main supplier. The lack of diversification of supplies and the huge expected increase in demand for these materials, resulting from the exponential growth in the production of electric cars, pose threats to supply chains. One of the solutions is the development of effective technologies for battery recycling. There is a risk of losing many jobs as a result of changes in the automotive market and the withdrawal of classic cars from production. Taking into account the scope, pace, and changes resulting from changes in the automotive industry, in particular in the field of materials, one should expect their global impact on the economy.

Since the 1940s, the airfoil shape has undergone many significant changes, and the technical level has gradually realized from subsonic to transonic and then to supersonic. This paper mainly analyzes and summarizes the design characteristics and changing trends of the airfoils by analyzing the aerodynamic shapes of the first to fifth generation fighter airfoils. The performance that the airfoil needs to meet gradually improves over time. In the new era, the demand for airfoil design is more diversified. Countries pay attention to improving the aerodynamic performance, stealth performance, mechanical stress structure, material technology and morphing technology of airfoils. To meet the development needs of the new generation of fighter, this paper proposes that it is necessary to improve the level of stealth technology and morphing technology of fighters, and at the same time, improving of the CFD and the Navier-Stokes equations matter a lot. Whats more, the comprehensive application of multidisciplinary technology may make the future fighter more information and intelligent.
A review on the hypotheses leading to the creation of quantum mechanics
Authors: Yang Haobin
Published: August 2023

On April 27, 1900, the famous British physicist William Thomson (Baron Kelvin) delivered a speech entitled "The Dark Clouds of the Nineteenth Century on the Theory of Heat and Photodynamics" at the Royal Society. In his speech, he pointed out that, in the "edifice of physics" based on force and heat, there were two hypotheses that could not be solved at that time. One was the ether medium and the other was the black body radiation. Later, the flaws of physics were proved and the quantum mechanics and relativity were thus created. This paper introduces the origin of the concept of aether and the inference of its reality through subsequent scientific experiments. It also illustrates the emergence of a series of hypotheses such as blackbody radiation, which laid the foundation for the beginning of quantum physics.

The development of rowing performance evaluation technique using high-speed imaging
Authors: Xia Kaichen
Published: August 2023

Rowing as an on-river sports has a long history dating back to the 16th century. The deeper understanding of fluid dynamics theory and the development of advanced material and manufacturing science and technology have inevitably fueled the continuous improvement on the world record of the rowing sports. The current paper focuses on the accurate extraction of the kinematics information including the boats location, velocity, and acceleration, resulting from the athletes rowing motion. A consumer-level digital camera is used for imaging the rowing motion at 50 frames per second from a distance, corresponding to a specific field of view ranging from 12 m 36 m. Furthermore, due to large-scale imaging lens distortion, the physical resolution is varying significantly due to imaging location change. A video-specific calibration method using fourth order polynomials are developed to calibrate the physical resolution of each pixel based on the physical length of the boat. The resulting data is pixel-level accurate and provides detailed record for athletes training. The acquired information is extremely useful in gauging athletes performance and can be further analyzed to provide concrete technical improvement advice.
TSGAN: Individual treatment effect estimation for multi-intervention with continuous dosage
Authors: Lu Houhan , Zhang Xinyu , Bu Evan , Zhu Ruisi , Jiang Yifeng , Tian Peifan
Published: August 2023

In recent years, causal inference has achieved great results in recommendation systems, causal chain analysis, and individual treatment effects. The individual treatment effect (ITE), also known as the complier average treatment effect (CATE), is the focus of research in the medical, economic, and political fields. Its purpose is to solve the problem that it is impossible to predict an intervention's impact on individuals when interventions effects vary due to individual differences. Today's research focuses on estimating the counter-fact, that is, predicting the difference in treatment effect between individuals receiving one treatment and receiving another treatment. However, the above study was limited to two interventions and did not consider the issue of therapeutic dose. In this paper, a method combining both the idea of matching that prevalent in traditional ITE estimation, and a generative adversarial neural network (GAN) is proposed to achieve individual effect estimation under multi-intervention with continuous dosage intervention. This paper first proposes the idea of treatment effect space (TES), and proposes a neural network based on GAN, uses an improved discriminator, which takes a different approach from common GAN, using multiple discriminators in parallel structure to achieve discrimination of true samples from treatment space. The model was tested and validated under semi-simulated data.

Authors: Zhou Hongkun
Published: August 2023

Variable cycle engines (VCE) have always been a hot topic in aircraft engine research. Because of its variable thermal cycle characteristics, it has a wide range of optimum operating conditions (altitude, flight Mach number). In this paper, a typical double bypass variable cycle engine is used as the object of study, and the Gasturb11 software is used to simulate the engine in two main modes at different altitudes and Mach numbers, to observe the engine operation performance, as well as the relationship between the range and endurance from the derivation of cruise equation. The results show that VCE has a best thermal cycling pattern for a given altitude and Mach number, and for a range of lift-to-drag ratios, resulting in the longest range or endurance of the aircraft. This paper investigates the relationship between range, endurance and thrust of a variable cycle engine and altitude and Mach number to help make the VCE better suited to the needs of an aircraft with multiple missions, long range and high endurance.

However, we first carefully chose 2 binary systems from a catalog of 4584 eclipsing binaries to give a fundamental analysis through details in the light curves. Then comes the ways of detecting exoplanets inside extrasolar systems, mainly transit, radial velocity (or Doppler method) and microlensing. The methods also yield some of the properties of the exoplanets, such as their orbital period, mass, radius, etc. Finally, we will talk about both the advantages and disadvantages of our methods, and with some future improvements. We use python to help us visualize the data observed in the light spectrum, and the code will be placed in the last part of this paper.
Radiation belt dynamics and the decay time scale of electrons at different energy and altitude
Authors: Guo Zhiyuan
Published: August 2023

Since the discovery of the Radiation belt, scientists have had strong interests in the magnetized space that protects us from the bombardment of solar storms. Early satellite observations show that the radiation belts consist of energetic particles and exhibit a two-belt structure. The outer belt electrons are accelerated during geomagnetic storms, while the inner-belt is mostly formed by the cosmic ray. Recently, the NASA Van Allen probes discovered a temporary storage ring that locates in the middle of the two belts when solar storm event occurs, and the radiation belts may exhibit a three-belt structure. This study aims to analyze the three-belt structure from short-term variation and long-term variation. We calculated the decay time scale in the heart of the radiation belt which describes the lifetime of the high-energy electrons. The study of the decay time is of great significance in understanding the dynamics of the whole radiation belt.
Simulation study on dynamic characteristics of SiC MOSFET
Authors: Che Haoming
Published: August 2023

In this paper, the third generation power MOSFET is introduced, and the physical model based on silicon based MOSFET is improved for SiC MOSFET, and the commercial planar gate and trench gate 1.2kV SiC MOSFET are simulated. The accuracy of physical modals is tested by comparing the static characteristics with commercial ones. The dynamic characteristics of two MOSFETs are simulated by inductively clamped double pulse circuit, and the circuit parameters are analyzed according to the static characteristics of the devices. The switching loss of the two MOSFETs is calculated and compared by using TCAD software. In the two devices with the same volume, the trench gate structure has the larger switching loss.
Basic theorems in local class field theory and some further exploration
Authors: Chen Peiwu
Published: August 2023

The relation between the abelian extension of a field and the topological groups of the field itself can be constructed using class field theory. In this piece of writing, the author will introduce the fundamental theorems of local class field theory by conducting a method of literature study. These theorems are the Reciprocity Law and the Existence Theorem, respectively. In addition to that, the author will discuss several unresolved issues in class field theory and provide examples of their applications in number theory. In class field theory, the results can be shown in two different ways. Both can be considered broad strokes. The first step is to demonstrate that the local case is true. By employing the methodology of cohomology and the theory of Lubin and Tate, one can demonstrate the Local Reciprocity Law and the Local Existence Theorem. The fundamental theorems in the global case are going to be demonstrated by utilizing the local results in conjunction with cohomology. Directly demonstrating the Gocal Reciprocity Law is another viable option.
Formal topological description of three-dimensional topological entities based on k-dimensional pseudo-manifold
Authors: Zhao Xiaoli
Published: August 2023

This paper clarifies the necessity of studying three-dimensional spatial data models, analyzes the research progress and existing problems of topological spatial relationship description methods, and proposes a complete and formal description framework of three-dimensional topological spatial relations based on point set topological theory and dimension expansion method. On this basis, the topological spatial relations existing in three-dimensional spatial objects are classified, and five fundamental topological spatial relations are defined. The mutual exclusivity and completeness of the minimal set of 3D topological space relations are proved. Based on point set topology and k-dimensional pseudo-manifold, this paper proposes the formal description of three-dimensional topological properties and spatial relations between spatial entities. The simplicial homology is applied to manifolds, the topological properties of three-dimensional space entities are revealed, and the formal description method of three-dimensional space entities is given through the geometric structural relationship between simplex and simplicial k-complex.
Algorithm speed-ups of 3x+1 convergence verification sieves
Authors: Ge Kevin
Published: August 2023

The 3x+1 Conjecture is a notorious open elementary number theory problem for its deceitful triviality. Several algorithms described in the past for the numerical verification for the convergence, one of which implemented an improvement of sieves. However, most papers focused on theoretical aspects of the sieve, and empirical results were rarely discussed. This paper presents data from implementing sieves on a relatively high-level language, as well as some helpful unmentioned rudimentary algebraic facts about sieves. Several algorithms for convergence verification of the 3x+1 Problem had been developed since the 1970s. This paper tests an algorithm presented in a 1999 paper and explores the runtime growth to input size.
A discussion on mathematical models for option valuation
Authors: Xu Kang
Published: August 2023

Options as a type of financial derivatives have become increasingly popular in recent years; therefore, understanding how to value options as a derivative is crucial. To analyse the problem, we can use mathematical stochastic analysis from the perspectives of risk management and return maximisation, and then develop an option valuation model. Using a literature restatement approach, the mathematical model of option valuation is examined in this study. Bachilier introduced the option valuation model in 1900 as a breakthrough in the study of financial mathematics. In the 1860s, the asset pricing model was introduced, followed by the famous B-S formula published by F. Black and M. Scholes, which is also used to research option valuation. The above-mentioned mathematical models have been refined and are now frequently utilised in the options market. They can also be used as a criterion for buyers to determine the value of options, thus it is important to investigate this subject, which will be the subject of this paper.
The Effect of Shifting to Student-Centered Learning: Implementing Student-Centered Reading
Authors: Minalla Amir Abdalla
Published: August 2023

The "traditional" forms of teaching are extremely familiar to students, who frequently favor learning that is focused on receiving instruction and reproducing knowledge. This study aims to examine the effects of these traditional forms of teaching practices, such as teacher-centered learning on EFL learners' engagement in implementing student-centered reading. The study uses an observation checklist and interview as tools for collecting data from twelve EFL elementary reading classes and their teachers. The statistically analyzed data has shown that whenever reading activities demand deeper, personalized discussion, the learners engage less and rely more on their teachers for assistance. When interacting with non-communicative tasks, EFL students take full ownership of their own learning; however, when interacting with communicative tasks, they require teacher prompting. Furthermore, learners' collaboration with each other on achieving reading tasks was, in most cases, either done to some extent or in a very limited range. Thus, EFL learners maintained dependency in carrying out reading activities through their preference for non-communicative tasks over communicative tasks and their collaboration upon reading activities in a limited range. Based on this, the design of communicative reading activities demands prompting, and learners need to be encouraged and guided for engagement. Students may be more receptive and interested if they are more informed about the advantages and effectiveness of student-centered learning. In spite of the effectiveness of student-centered learning in many contexts, it needs to be redefined to fit within the culture and specific EFL learning and teaching contexts.
