In electronic circuits that use various integrated circuits (ICs), ICs may malfunction while assembled, used, and repaired. There are numerous ways to verify that ICs are operating, such as by measuring basic current and voltage with a VOM meter. However, many sophisticated operations are hard to measure and test, and the accuracy of the tests is low and takes a long time. Thus, it is crucial to have a tool that can rapidly determine whether or not integrated circuits are operating correctly. The purpose of this article is to develop a tool for testing the functionality of logic gate ICs. By modeling its properties using the truth table of the specific IC, the device employs an Arduino to verify the condition of the gates in a logic gate IC. After successful simulation and testing, they are assembled to form a final device.

The theory of differential equations arises from the study of physical phenomena. This field has various applications in science and engineering. The study of qualitative properties for each mathematical model plays an important role, attracting the attention of both theoretical and applied researchers. Normally, the most significant qualitative property to be studied first is the existence and uniqueness of the solutions of each mathematical model. However, proving existence and uniqueness results for mathematical models where the source function has a singularity is a difficult problem and requires many different techniques. In this paper, we establish some new conditions suitable to achieve the unique solution criterion for ordinary first-order differential equations. To obtain the desired results, we have improved the methods that have been used to prove the results in the work of Krasnosel'skii and Krein (Krasnoselskii and Krein, 1956). In addition, we also provide an example to illustrate the theoretical results.

Traditional education in Southern Vietnam developed through two main periods: the era of the Nguyen Lords (1698-1802) and the reign of the Nguyen emperors (1802-1862). This article focuses on education development in Southern Vietnam during the reign of the Nguyen emperors. Despite the numerous difficulties experienced during the decline of the feudal regime, the Nguyen emperors made significant efforts to promote education in the South. The royal court showed commitment, introduced reforms, and created favorable conditions for educational activities to thrive, resulting in greater academic success compared to the previous period. Alongside civil service examinations, the establishment of public schools and supporting educational institutions was also actively promoted. The institutionalization of state-led educational activities inherited the achievements of the earlier period and marked the consolidation of educational functions during a historical development phase

The study investigates the challenges faced by Food Technology students at Thu Dau Mot University in mastering English reading and writing skills. The findings reveal that limited vocabulary and grammar knowledge significantly hinder students' proficiency in these areas. For reading, students struggle with insufficient vocabulary, poor comprehension strategies, and a lack of background knowledge, making it difficult to understand texts, identify main ideas, and interpret references. Similarly, writing is affected by challenges such as improper grammar usage, insufficient vocabulary, awkward phrasing, and issues with sentence construction. Mistakes in punctuation, spelling, and word order further reduce the quality of written work, limiting students’ ability to express ideas clearly and cohesively. These difficulties stem from a combination of linguistic limitations, lack of exposure to English, and insufficient support in structured learning strategies. The study highlights the urgent need for targeted interventions to address these challenges. Proposed solutions include vocabulary enhancement exercises, grammar-focused sessions, structured reading techniques, and writing workshops. Additionally, integrating modern tools like AI-powered learning applications can provide personalized feedback and improve overall proficiency. By adopting these strategies, students can gradually overcome their difficulties, enhancing their reading and writing skills to meet both academic and professional demands. The findings emphasize the importance of consistent practice and tailored learning approaches in language development.

This article examines the role of social networks and informal institutions in facilitating the resettlement and socio-economic integration of Vietnamese returnees from Cambodia in the Tri An Lake region, Dong Nai Province. In the context of statelessness and the absence of legal identification, these returnees faced significant barriers in accessing official support from local authorities. Under such circumstances, kinship-based networks, fellow migrant connections, and local community ties—together with informal support mechanisms —played a pivotal role in providing essential resources such as shelter, livelihood opportunities, informal credit, and emotional support. Drawing on oral history interviews with Vietnamese returnees who have resettled around Tri An Lake since the late 1980s, the study reveals that these social connections and informal institutions helped individuals navigate initial crises and contributed significantly to their long-term stability and integration.

There are many methods and software for simulating materials in practice today, each software or computational method has its own advantages and disadvantages. In the process of studying and researching material simulation, we found that the VASP software combined with the Density Functional Theory (DFT) method is perfect up to this point. Reliability, accuracy, and low resource and time consumption during the calculation process are the standout advantages of this combination. DFT calculations on VASP require the precise construction of input data, including the input files, and it is not necessary to write code to process the output data, which is a significant advantage compared to other methods. Output data is processed through commonly used support software such as Origin and VESTA, which is an advantage of this simulation calculation method.

In this study, molecular dynamics simulations were employed to investigate the influence of pressure on the structural properties of silver (Ag) at 300K. The results reveal that an increase in pressure leads to a reduction in nearest-neighbor distance, a promotion of local ordering, and a transition from a largely disordered state to a predominantly face-centered cubic FCC crystalline structure. At intermediate pressures, both hexagonal close-packed HCP and body-centered cubic BCC phases are observed; however, these phases diminish as pressure rises, with FCC becoming the prevailing phase at higher pressures. These findings demonstrate that pressure is a key factor in driving phase transitions and improving crystallinity in metallic systems.
