Nghe An is a long-standing area inhabited by ethnic minorities such as: Thai, Tho, Hmong, Kho mu, O đu. It was in this land that the ethnic groups have together established villages, build “muong”, created cultural features imbued with ethnic identity, contributing to the formation of cultural characteristics of the western Nghe An. However, in the flow of socio-economic life, the influence of the guidelines and policies of the State, in the past few decades, many traditional cultural phenomena in the lives of ethnic groups are on a declining trend and increasingly disappearing. The article presents the results of research on the culture of ethnic minorities in Western Nghe An in the current context, thereby proposing a number of solutions to contribute to preserving and promoting the cultural identity of ethnic minorities in the western region of Nghe An.

The study aimed to develop and validate the quantitative procedure of lead and cadmium in tuberous roots of Rehmannia glutinosa varietes 19 by atomic absorption spectroscopy. Research results show that there is a strong linear correlation between lead and cadmium concentrations with absorbance, with the function form of lead is Y = 0.0138X + 0.1131, r = 0.9998 and the function form of cadmium is Y = 0.1027X - 0.0037, r = 0.9999. The procedure has high specificity, good reproducibility with RSD < 5% and the detection limit for lead LOD = 0.087 ppb, equal to 0.015 ppb for cadmium. Quantitative limit for lead LOQ = 0.290 ppb, for cadmium LOQ = 0.049 ppb. This procedure is suitable for the quantification of lead and cadmium in tuberous roots of Rehmannia glutinosa varietes 19.

In this work, we will present detailed calculations to derive the exact formulas of the triple and quartic self-couplings of all gauge bosons predicted by the general 3-3-1 model with an arbitrary parameter β used to classify different 3-3-1 models. We show that our result is consistent with all previous results calculated for particular β values. The respective Feynman rules are introduced for further studies on physical processes relating to these gauge bosons.

Sentiment analysis is a critical job in natural language processing. Controlling and evaluating customer feedback on their goods is a task that companies are especially interested in. For reading comprehension problems including attention processes, the BiDAF model is developed. Attention processes have recently been expanded and effectively used for natural language processing problems. In this study, we use the BiDAF model to perform sentiment analysis on Amazon product evaluations at the sentence level. The BiDAF model is a multilayered processing model that reflects context at multiple levels and uses the BiLSTM model. Furthermore, we investigate the sentence's attention weight distribution using the attention mechanism. With a recall measure, the model achieves an accuracy of up to 99.9%. We discovered that the attention weights of important phrases are equivalent to, if not higher than, the attention weights of sentiment words in the sentence.

In the first two decades of the 21st century, Vietnam has been proactive and active in international integration in all fields. Cultural exchange, cooperation, and international integration are considered bright spots. That has contributed to enhancing understanding, consolidating, and deepening the relationship between Vietnam and other countries, organizations, regions, and the world; at the same time, contributing to the strengthening of integration in other fields, maintaining stability, socio-economic development, and raising Vietnam's position and role in the international arena. The article focuses on analyzing Vietnam's international cultural integration guidelines and policies, clarifying the implementation process and achievements in different aspects. Since then, the limitations have been pointed out, and some solutions have been proposed to further promote the international cultural integration of Vietnam in the context of deepening cooperation.

From the late 19th century, Vietnamese literature started to change and transform from the medieval to the modern. In the early 20th century, especially from the 1920s onwards, Vietnamese literature gradually entered the trajectory of modern literature quickly and comprehensively with the appearance of many talented writers with remarkable artistic innovations. This is clearly shown in the short story, the “short narrative” genre, which is dynamic and can easily catch up with the changes of society in general and of literature in particular. The process of modernization of short stories in this period was revealed in many aspects, especially in terms of plot, and artistic language, which will be elucidated in this article.

Breast cancer, a prevalent form of cancer in women, presents various categories that pose challenges in defining specific treatment approaches. Immunohistochemistry, a combination of immunology and histology, has made significant advancements in identifying specific surface receptors on cancer cells. This information serves as the basis for guiding appropriate treatment regimens and predicting prognosis for patients. A survey conducted on 75 tissue samples revealed the diversity of breast carcinoma types, with the infiltrative tubular form being the most common, accounting for 73.3% of cases. By utilizing immunoassay markers on these tissues, the expression rates of ER (estrogen receptor), PR (progesterone receptor), and Her2/neu were determined to be 29.2%, 52%, and 22.7%, respectively. Classification of breast cancer based on these markers showed that the ER/PR+HER2- group accounted for 24% of cases. The ER-/PR+HER2- group accounted for 18.7%, while the ER+/PR+HER2+, ER-/PR+HER2+, and ER-PR+Her2+ groups each represented 12% of cases. The ER-/PRHER2+HER2+ group accounted for 8%, and a subgroup where all three markers were negative accounted for 22.7% of cases. Estrogen and progesterone expression showed a moderately positive correlation (0 < r = 0.445 < 0.5; p <0.05). However, the expression of Her2/neu in ER-negative tumors did not show statistical significance (p > 0.05) and exhibited a reverse correlation with r = -0.016.
乳腺癌是妇女中常见的一种癌症，其种类繁多，对确定具体治疗方法构成挑战。免疫组织化学是免疫学和组织学的结合，在识别癌细胞表面特异性受体方面取得了重大进展。这些信息可作为指导适当治疗方案和预测患者预后的基础。通过对75份组织样本的调查，发现乳腺癌类型的多样性，以浸润性管状形式最常见，占73.3%。利用免疫分析标记物检测这些组织中雌激素受体ER、孕激素受体PR和Her2/neu的表达率分别为29.2%、52%和22.7%。基于这些标志物的乳腺癌分类显示，ER/PR+HER2-组占24%的病例。ER-/PR+HER2-组占18.7%，ER+/PR+HER2+、ER-/PR+HER2+和ER-PR+ HER2+组各占12%。ER-/PRHER2+HER2+组占8%，三种标志物均为阴性的亚组占22.7%。雌激素与孕激素表达呈中度正相关(0 < r = 0.445 < 0.5;P < 0.05)， r = -0.016呈负相关。
