Abstract: In data mining, we can use symptoms suffered by patients for a reference in classifying positive and negative Covid-19 patients using data mining. Random Forest and logistic regression are two data mining algorithms with high accuracy, precision, and sensitivity in data classification. This study compares the random forest and the logistic regression algorithm - where we use the lasso and ridge regulations - on classifying positive and negative Covid-19 patients based on their symptoms. From 5434 data used in the data set, the evaluation results show that the random forest algorithm is the best in terms of accuracy, precision, and sensitivity compared to other algorithms, while the logistic regression algorithm with ridge regulation is the worst. The random forest algorithm is the most reliable in classifying patients with positive Covid-19, while the logistic regression algorithm with ridge regulation is the least reliable. Also, the random forest algorithm is the most reliable in classifying patients with negative Covid-19, while the logistic regression algorithm with lasso regulation is the least reliable. Keywords: classification;covid-19;data mining;logistic regression;random forest. Abstrak: Dalam data mining, kita dapat menggunakan gejala yang diderita pasien sebagai acuan dalam mengklasifikasikan pasien positif dan negatif Covid-19 menggunakan data mining.

A Moment in the History of Realpolitik Diplomacy in the Light of the 1972 Shanghai Communique
Authors: Wang Yutong
Published: December 2022

2022 marks the 50th anniversary of the 1972 visit by Richard Nixon to China and the signing of the Shanghai Communiqué, in which China and the US were able to initiate diplomacy and consequently soften the precarious global relationship at the time, known as the "Sino-US rapprochement" in history. Recently, we have all witnessed the intensity a Taiwan visit by the US House Speaker Nancy Pelosi could bring. Thus, it's essential to reflect on history for modern politics. Many people, even historians, scarcely know much about the Shanghai Communiqué or disregard its significance The fact that the Shanghai Communiqué exists as literal evidence of the Sino-US rapprochement discloses the realism of the senior leadership from both countries behind the façade of ideology. This paper will examine whether the Shanghai Communiqué in 1972 was a moment of realpolitik diplomacy in history or not. Looking at the history of the Cold War period from a long-term perspective, this paper claims that China has taken on long-term underlying realpolitik standpoints on various issues long before the culmination of this moment. This paper has comprehensively analyzed the domestic and international problems impacting Mao's and Nixon's administrations and the shifting geopolitical relations that altered China and the US's diplomacy in a similar direction to elucidate this matter further. At the same time, this paper also provides historical reflections on the current Sino-American relations and power transfer process.
Mexican Retrogrades in the Wave of American Film Culture
Authors: Zhang Jiayi
Published: December 2022

As one of the most penetrating media, film is an important expression of national cultural soft power. From the beginning of the 20th century to the present, American film culture has swept the world, directly or indirectly dominating the global screen entertainment. Relying on its mature film industry, the United States has rapidly penetrated its culture and values to the world, affecting the cultural identities of other countries. (Under the long-term hegemony of "Hollywood" values, the Mexican film culture as its neighbor has been seriously affected. In Hollywood films, Mexico seems to be synonymous with "chaos", "poverty" and "violence". For Mexican filmmakers, how to keep the Mexican style in the film in the "encirclement and suppression" of American films is the first problem, and then the goal is to show the real Mexico to the world. In response to this situation, some Mexican filmmakers have successively tried a genre-based creative path, transplanting the Hollywood genre film model into the local narrative, in order to achieve a balance between commerciality and artistry. This is also the goal that a group of Mexican filmmakers of the new genre have always pursued. They reject the domineering "cultural fusion" of Hollywood, but take the initiative to choose the "wall" that crosses national borders, galloping into the global film industry with Mexican concepts and creativity. One of the worthiest of exploration is the Mexican director Alessandro Gonzalez Inarito, because he has lived in the United States for a long time, so he has witnessed the situation of Mexicans in the United States, in his film The two perspectives of the United States and Mexico have appeared many times, intuitively revealing Mexico in the eyes of Americans. And almost all the films he shoots contain Mexican elements, trying to break the world's stereotypes about Mexico through the perspective of Mexicans. In the past ten years, Mexican films have made good news on the international stage and become one of the most active countries in the film industry in the world. Therefore, through the study of Alessandro's films, it is necessary to break the Mexico established by the United States and to re-establish the understanding of Mexico and its films.

The Kierkegaardian and Heideggerian Anxiety: on To Be and Being
Authors: Li Bingrui
Published: December 2022

The terminology of anxiety is included in both Kierkegaard’s and Heidegger’s analysis on human existence, and in both cases, it takes place when a man realizes his responsibility for his own being. Yet Kierkegaard introduces anxiety in constructing individuals’ lonely journey towards god, Heidegger mainly sees anxiety as a critical point in Dasein’s reaching a structural wholeness. In this essay, I will respectively illustrate Kierkegaard’s and Heidegger’s accounts on anxiety, including anxiety’s subjects, the occurrence of anxiety, and the solution to anxiety; then, I will analyze the differences between the two seemingly-similar views on anxiety by incorporating the two views into the philosophers’ core philosophies, and finally lead to the conclusion that while Kierkegaard noticed anxiety in a ‘to be question’, Heidegger points to anxiety to solve the ‘being question’.
Study of Taking Advantage of the Corner 3 Improving the Team's 3-point Efficiency
Authors: Wu Shenshu
Published: December 2022

The corner three plays an important role in many NBA tactics. Players tend to be able to hit 3-pointers at a higher rate from the corner 3-point range, probably because the corner 3-pointer is closer to the rim. However, is the existence of the corner three really meaningful? I thought taking advantage of this position would make the 3-pointer more efficient, but the math proved it couldn't. At the same time, the Kendall coefficient proves that the three-point shooting rate in the corner does not decrease or increase due to the attention of the enemy, and only the three-point shooting rate can directly affect the three-point shooting rate in the bottom corner. I used excel to simulate the relationship between 3-point shooting and corner 3-point shooting for all teams since the 2015-16 season, and used the 2021-22 NBA league average 3-point shooting percentage to simulate the value, trying to make this team The team's corner three-pointer improves the team's three-point efficiency to the greatest extent, but in the end it only improves by two thousandths, which is an extremely low value, which means that the corner three-pointer is not as useful as imagined. The above results provide a reference for understanding three-point shooting rate.
Cross Dressing as (Wo)Men: The Implicit Male Gaze in a “Feminist” Ballet
Authors: Luo Xiaoyue
Published: December 2022

The Red Detachment of Women is a Chinese revolutionary ballet that is often characterized as feminist based on its portryal of female soldiers. This view is based on the incomprehensive view that the era of its production was devoid of desire, sex, and gender. This article, using the 1970 filmed version of the ballet, utilizes crossdressing as a lead and through an analysis of costumes, identifies the gender differences between the characters on stage. Furthermore, the article explores actor-audience interactions and argues that the gender difference is initiated by an implicit male gaze embedded within the production. The Red Detachment of Women is significant as a specimen of gender politics during the Cultural Revolution, as well as an example of undetected masculine view in popular culture production.

Trust and Investment Game between Different Types of Education
Authors: Huang Han
Published: December 2022

This paper systematically analyzes the identity and trust among different class groups through the virtual questionnaire of the small investment game with the penalty mechanism introduced on the basis of the trust investment game. We analyze public school’s students and private international school’s students to represent two class groups in society. The basic survey results show that both groups have a tendency to choose sample of private international schools as trusted partners; this is most likely the result of the social identification with different classes. Under the same conditions of return on investment, these two groups have different trust decisions. This may be due to the different expectations of different groups for the return of others. There is little difference between groups in punishment decisions.

Published: December 2022

Global warming and the accumulation of organic waste constitute a serious environmental problem. Therefore, microbial fuel cells (MFC) are an eco-friendly device that have significant capability for the production of electricity using biodegradable waste as fuel. Microorganisms used as catalysts in the anode compartment, execute a principal function in operating MFCs. The present study was conducted to isolate and to screen potential bioelectricity generating microorganisms from dumpsite soil samples and also to construct a domestic dual-chambered microbial fuel cell (MFC). Streptomyces fimicarius was found to be the best isolate for the degradation of cellulose and the production of bioelectricity. The bacterial isolate was identified based on morphological characteristics, biochemical characteristics and molecular identification using 16S rRNA. Double-chambered MFC was constructed by using two polypropylene plastic containers of 1.4 L volume each. The two chambers were joined by using an agar salt bridge and carbon rods were utilized as electrodes. The generation of electricity by the isolate was compared using glucose and cellulose as sole carbon source in a minimal medium. The maximum voltage was found to be 322 mV in the presence of cellulose used as substrate after 5 days of incubation at room temperature and last for 10 days.

Authors: Ribeiro Constantino Gonçalves , Raptopoulos Luciano Constantin , Dutra Max Suel
Published: December 2022

The applications of UAVs (Unmanned Aerial Vehicles) are growing up and becoming part of many daily tasks in many organizations. However, as matter of fact, the use of a UAV does not mean the decreasing of operational complexities and, consequently, the costs of perform its tasks. Sometimes this high cost is connected to the dependence of well-trained operators and huge remote control facilities to operate asophisticated UAV's. This paper proposes a robotic flying crane using UAV that can perform its tasks as much independent of human interaction as possible, and with a minimum connection to any mission control facilities. This independence will beachieved by embedding the path mission control into the UAV. As path control is embedded, the UAV will have less connections issues with its control center and will be less dependable of human interaction. To prove this concept all kinematics anddynamics of a light than air vehicle (blimp) is develop; a prototype of an embedded parallel-distributed compute was constructed; and new procedures to resolve navigations and collision evasions issues are proposed. The new evasion procedures were implemented into a simulator and a new parallel / distributed program for optimal path discover was developed to be used into the cluster prototype. Tests of the evasion procedures simulator were satisfactory and speed up of embedded proposed cluster showed better performance of proposed framework.

A “New” Method in Archaeology: Architectural Energetics
Authors: Kaner Ebru
Published: December 2022

The question of how the ancient structures, which evoke admiration among visitors to excavation sites, ruins, and museums, came to be, has puzzled almost everyone. Although experimental studies have sought answers from time to time since the 1900s, many questions were answered with the introduction of the field of study of architectural energetics into archaeology in the 1980s. In this study, architectural energetics is used to answer many unanswered questions, such as how the labor force was calculated and whether the economy of the society could be understood with the resulting costs, what kind of social structure this society had, how the labor force was organized, the distribution of gender roles in the workforce, and how to calculate the population of the settlement. The goal is to find answers through the method and provide confirmation of the existing information. Although the use of this “new” method has been applied to specific architectural structures in many settlements in various parts of the world or to the texture of a city or settlement, this process has not yet been the case for Anatolian archaeology. The aim of this study is to practice the method of architectural energetics in Anatolia in the future.
Random lasers based on inverse photonic glass structure
Authors: Nguyen Hoang , Nguyen Toan , Le Hai , Ta Duong
Published: December 2022

Random laser has attracted much attention because of its unique physical properties and potential applications in lighting, speckle-free imaging, biosensing, and photonic devices. In this work, we confirm that scattering plays a vital role in random lasing. Then, we investigate lasing properties of random film lasers with two scattering structures, including polystyrenemicroparticles and air voids embedded in a polymer matrix with organic dye serving as a gain medium. These two structures are called direct and inverse photonic glass, respectively. The result indicates that random lasers based on inverse photonic glass have a lower threshold. Following this achievement, we implemented inverse photonic glass into microspheres to obtainrandom microlasers of different sizes. Our work shows that inverse photonic glass structure is an excellent medium for random lasers with a wide range of sizes and dimensions. Especially, the obtained random microlasers are promising for applications in microsensors and photonic integrated circuits.

Authors: Nguyen Tuan Anh  , Dinh Van Dr Hien , Tran Ngoc Thanh  , Vu Tung Lam
Published: December 2022

Using heat-resistant fiber-reinforced phenolic composite materials (carbon fiber, glass fiber, etc.) to protect the rocket motor from high temperature has confirmed its superiority thanks to its thermal insulation and high-temperature resistance. The improvement of thermal protection properties of materials to diversify the thermal protection material family is a growing trend. Accordingly, this paper focuses on determining the influence of the percentage of carbon nano powder (0-14%) on the thermal, physical and mechanical properties of carbon fiber/phenolic matrix composite (CPC) in order to find out the extent of reasonable proportion of carbon powder to improve thermal protection.

Published: December 2022

We numerically demonstrated a dual-band metamaterial absorber (MPA) operating in low frequency range based on a flexible polyimide substrate. For the flat configuration, two absorption peaks are obtained at 450 MHz and 1.47 GHz with absorption over 90%. The ratios of the periodicity of unit cells and thickness to the longest absorption wavelength are 1/12 and 1/114, respectively. Especially, our MPA is insensitive with polarization and stable with the oblique incidence angle of incoming electromagnetic waves. The proposed MPA maintains an absorption over 90% when incident angle is increased up to 60o. Furthermore, since structure is wrapped and attached to cylindered surfaces (the varying radii from 200 to 500 mm), new absorption peaks can be obtained at higher frequency range. For both flat and curvature states, the absorption mechanism is explained by the magnetic resonance and the perfect impedance matching phenomena.

Published: December 2022

Recently, thermal imaging modules equipped for infantry soldiers have been a trend to improve the combat ability of soldiers. Soldiers have to perform many different tasks at the same time, so it is necessary to equip them with the tools of automatic target detection, especially human objects detection, in practice. Hence, there is a need to intelligently optimize the effectiveness of thermal imaging equipment. New artificial intelligence and deep learning(DL) approaches are applicable methods that show superior accuracy compared to previous methods. However, state-of-the-art DL methods depend on the generality and diversity of the training data set. To address this issue, our paper presents the DeepThermal Outdoor thermal imaging data set, which is collected from equipment mounted on the body of infantry at various terrain locations. The labeled dataset focuses on human objects with different locomotion postures, and it contains 10,190 images and 22,464 labeled human-objects. Finally, the experiment is conducted with several DL methods using the proposed dataset, and the results show its contribution to the improvement of the performance of DL methods to detect humans on thermal images as well as to evaluate the practical applicability of a DL.
