Large language models(LLMs),such as ChatGPT developed by OpenAI,represent a significant advancement in artificial intelligence(AI),designed to understand,generate,and interpret human language by analyzing extensive text data.Their potential integration into clinical settings offers a promising avenue that could transform clinical diagnosis and decision-making processes in the future(Thirunavukarasu et al.,2023).This article aims to provide an in-depth analysis of LLMs’current and potential impact on clinical practices.Their ability to generate differential diagnosis lists underscores their potential as invaluable tools in medical practice and education(Hirosawa et al.,2023;Koga et al.,2023). 展开更多

However, the reliability of text-grading for graded readers remains questionable. Whether they show linguistic difference across levels needs further research given a shifted emphasis on multidimensional features. The study used Co-Metrix to give an assessment on graded readers’text-grading both under unidimensional and multidimensional indices, providing a testimony to publishers’original design and to the feasibility against the new trend. It indicated that across-grade difference only partly corresponded with publishers’text-grading rationale that focused on surface features. But it made no sense in linguistics at a deeper level since no overall difference was found. Therefore, the reassessment and design of graded readers were suggested to take account of multidimensional features for across-grade difference. 展开更多

A quadrature mixer with a shared transconductor stage is analyzed,including voltage conversion gain, linearity, noise figure, and image rejection. The analysis indicates it has better performance than a conventional Gilbert mixer pair in commutating mode. A quadrature down-conversion mixer based on this topology is designed and optimized for an ultra high frequency RFID reader. Operating in the 915MHz ISM band, the presented quadrature mixer measures a conversion gain of 12.5dB,an IIP3 of 10dBm, an IIP2 of 58dBm, and an SSB noise figure of 17.6riB. The chip was fabricated in a 0. 18μm 1P6M RF CMOS process and consumes only 3mA of current from a 1.8V power supply. 展开更多

AIM: To determine the performance of novice readers (4^th year medical students) for detecting capsule endoscopy findings. METHODS: Ten capsule endoscopy cases of small bowel lesions were administered to the readers. Gold standard findings were pre-defined by gastroenterologists. Ten gold standard "targets" were identified among the 10 cases. Readers were given a 30-min overview of Rapid Reader software and instructed to mark any potential areas of abnormalities. A software program was developed using SAS to analyze the thumbnailed findings. RESULTS: The overall sensitivity for detecting the gold standard findings was 80%. As a group, at least 5 out of 10 readers detected each gold standard finding per recording. All the gold standard targets were identified when the readers' results were combined. Incidental finding/false positive rate ranged between 8.2-59.8 per reader. CONCLUSION: A panel of medical students with minimal endoscopic experience can achieve high sensitivity in detecting lesions on capsule endoscopy. A group of novice readers can pre-screen recordings to thumbnail potential areas of small bowel lesions for further review. These thumbnails must be reviewed to determine the clinical relevance. Further studies are ongoing to assess other cohorts. 展开更多

Among the sundry studies in China on John Donne's The Flea,there has been none done from the perspective of Reader-Oriented Theory to probe into the readers' roles in the construction of meaning.The present article under Wolfgang Iser's theories,in a further pursuit of the expansion of the gestalt of such studies on the poem,aims at exploring the readers' active roles in complementing,completing and recreating the textual meaning,and differentiating the implied reader and the actual reader through the poem as well as attempting to fulfill the construction of the reading cognitive model through the interpretation of the conceit the flea. 展开更多

Since the emergence of newspaper,the headline has been the necessity of a news report.The Newspaper headline which takes the crucial part in a news report has been given the responsibility to capture readers,especially in the environment of highly intense competition of this industry.Even with the application of high technology in the news industry,the significance of the headline is enormously strengthened rather than weakened.On the one hand,the mission of the headline determines its significance.And on the other,its characteristics help to achieve the responsibility.Therefore the particular language adopted in the headline,namely "headlinese",must contain certain features which could appeal readers' attention.This paper will focus on the characteristics of the English newspaper headline and find out how it captures readers. 展开更多
