We propose a new method for finding a zero point of a sum involving a Lipschitzian monotone operator and a maximally monotone operator, both acting on a real Hilbert space. The proposed method aims to extend forward-reflected-backward method by using inertial effect and variable metric. The weak convergence of the proposed method is proved under standard conditions.

This study explores the challenges and potential solutions for improving English language proficiency among non-English major students at Hoa Binh University. Through an analysis of current teaching practices, learner attitudes, and institutional structures, the research identifies critical factors contributing to poor English outcomes. Key issues include limited classroom hours, inconsistent entry-level proficiency, overcrowded classes, and a lack of motivation or clear learning goals among students.

A procedure for quantitative analysis of trace element magnesium (Mg) in soft capsules (mainly containing vitamins, trace elements and herbal extracts) using atomic absorption spectroscopy (AAS) has been established. The sample was treated to convert the Mg compound to Mg+2 ion form in solution by heating the sample on a boiling water bath with 10% hydrochloric acid solution, with the addition of Polysorbate 80. The sample was diluted with 1% hydrochloric acid solution, with the addition of LaCl3 in the final solution for AAS measurement.

This research presents an exploratory investigation of sales agents of international insurance firms in Hanoi, aiming to understand the connection between the Uncertainty Avoidance (UA), as discussed by Hofstede (2024), and the digital divide identified by Jan van Dijk (2020). The survey using Google Form was administered to 246 Vietnamese sales agents to collect data for SPSS analysis. The AMOS path diagram was then employed to test the hypotheses based on the conceptual model. The findings indicate that Uncertainty Avoidance negatively impacts the digital divide.

The study attempts to explore economic, financial, and institutional developmental factors that contribute to the growth of the size of corporate bond markets by using the data set from ten Asian economies (China; Hong Kong, Indonesia; Japan; Korea; Malaysia; the Philippines; Singapore; Thailand; and Vietnam). The empirical findings by generalized least squares model show that the level of economic development as shown by GDP per capita is one of the most important factors in the development of corporate bond markets.

The study also reveals that teachers need to use more role-based activities in which students should experience the role of employees. The role-based approach should be emphasised more in integrating career orientation in teaching science and STEM educational activities to achieve career-oriented competence for students.

Red yeast rice is produced from rice using Monascus purpureus fungus, which results in the red colour of the fermented rice. Red yeast rice has been used for a thousand years as a food preservative and in traditional medicine to support vascular and digestive health. This study used Liquid Chromatography-Mass Spectrometry (LC-MS/MS) to concurrently analyse citrinin and monacolin K produced by M. purpureus strain.

In recent years, economic activities and the work of humans have increased dramatically, destroying vegetation cover, and causing the natural environment to change significantly, which promotes the occurrences, development, and increase of landslides. This research uses the statistical index to determine the weight of each class in each factor and an analytical hierarchical process (AHP) to determine the weight of factors.

The aim of this study was to investigate the duplication events within the SABATH gene family in cassava using computational tools. By analyzing the similarities between coding DNA sequences, we identified potential duplicated gene pairs and examined their structures. In addition, we assessed the expression profiles of SABATH genes across various cassava tissues during key growth and developmental stages.

Microplastics are regarded as an emerging threat to water and other environments. The increasing use of plastics in agricultural cultivation has led to higher risks and more dangerous pollution of agricultural water. However, microplastics in agricultural water in Vietnam have neither been studied nor documented in any publication.

The problem of robust stability is investigated for a class of uncertain Hopfield-type neural networks with proportional delays. The existence and uniqueness of an equilibrium is first established using the homeomorphic mapping theorem. Then, by employing a modified Lyapunov–Krasovskii functional, a new criterion for the global asymptotic stability of an equilibrium point of the system is formulated.

To solve this problem, we use an improved genetic algorithm named GA-RT (Genetic Algorithm with Random Crossover and Negative Tournament Selection) and conduct experiments on the iMOPSE standard dataset. Experimental results show that the proposed GA-RT algorithm can effectively solve the project scheduling problem, achieving better performance compared to existing algorithms.
