Aim: Amniotic fluid embolism (AFE) is a potentially lethal obstetric emergency with a high maternal mortality rate. Our report details two successful cases of patients who developed non-overt disseminated intravascular coagulation (DIC) following cesarean section, likely induced by AFE, and were managed using a bundle transfusion strategy prior to experiencing massive postpartum hemorrhage. Methods: An aggressive bundle transfusion strategy was initiated upon early laboratory evidence of coagulo...

The canonical affinity-threshold model of thymic T-cell selection posits that thymocyte fate is determined by TCR-pMHC integrated affinity. However, this model fails to explain high thymocyte deletion rates, diverse TCR affinities in mature repertoires, and precise CD4/CD8 lineage commitment mechanisms. We propose a novel Differential TCR Signaling Model wherein the functional TCR signal is a relative comparison: TCRβ signal strength relative to a dynamic TCRα-derived self-reference threshold (T...

As an emerging force in global cultural exchanges, fan translators have brought new opportunities for Chinese classical literature to reach a worldwide audience. This paper takes the Romance of the Three Kingdoms Podcast created by fan translator John Zhu as a case study to analyze the characteristics of fan translator subjectivity. The research finds that fan translators, in terms of translation motivation, translation strategies, and community interaction, transcend the passive role of traditi...

Students with moderate intellectual disabilities face considerable challenges when engaging with traditional educational and training approaches, making the learning process demanding for both learners and their instructors. Against the backdrop of rapid advancements in artificial intelligence and natural language processing (NLP), cognitive computing has proven highly effective in creating interactive learning environments that respond dynamically to the individual needs of students with disabi...

This study uses a Gaussian plume model of airborne contaminants and artificial intelligence (AI) tools to evaluate the environmental impact of industrial emissions. It focuses on determining the major variables affecting the dispersion of airborne pollutants and calculating their concentrations downwind from the source of emissions. The study made use of hypothetical data from the NOAA website, which included a variety of physical and atmospheric variables like temperature, wind speed, emission ...

In the late Qing Dynasty, the 36 Weirs of Baishaxi Stream in Jinhua fell into frequent disputes. A particularly intense struggle for the water rights (legal or customary entitlements that determine how individuals or groups can access, use, and control water resources) of the Shanhe Weirs erupted between the Yin and Yu lineages downstream, turning local documents such as county gazetteers (xianzhi) and temple gazetteers (miaozhi) into a battlefield for power. The Yu lineage, whose water rights h...

Primary tumors of the vagina are extremely rare, accounting for less than 2% of gynecological neoplasms. Among these, mixed tumors with both epithelial and mesenchymal components are exceptional and rarely described in the literature. We report the case of a 50-year-old female patient with a mixed tumor of the vagina, which required multidisciplinary management. Through this observation, we discuss the clinical, radiological, and histopathological features of this rare entity, as well as the ava...

Methylmercury (MeHg) is an extremely dangerous and toxic organometallic compound that has been found to be persistent and recurrent in various compositions of the environment and is highly suspected to cause dangerous problems in ecosystems and public health owing to the accumulative and magnifying effects that it may cause in the food chain. Soil, one of the essential components for both the storage and partial release of MeHg, is a critical medium through which this compound moves within the e...

Large language models (LLMs), such as GPT-based systems, are transforming foreign language education by enabling personalized practice, instant feedback, and immersive interactions beyond traditional computer-assisted language learning (CALL) tools. The article outlines LLMs’ advantages over rule-based systems, analyzes applications across listening, speaking, reading, and writing skills, and addresses risks like overreliance and bias. It emphasizes pedagogy-aligned integration to maximize benef...

Henan Opera, a key Chinese intangible cultural heritage, faces significant barriers in global dissemination due to profound cultural distance extending beyond language to include aesthetic and contextual gaps. Traditional outreach methods struggle to bridge this divide. Drawing on qualitative data from multiple stakeholder groups and comparative case analysis, the study develops the AI-VR Integrated Communication Model as a new paradigm for understanding technology-mediated intercultural engagem...
