A Method for Detecting and Recognizing Yi Character Based on Deep Learning

Aiming at the challenges associated with the absence of a labeled dataset for Yi characters and the complexity of Yi character detection and recognition,we present a deep learning-based approach for Yi character detection and recognition.In the detection stage,an improved Differentiable Binarization Network(DBNet)framework is introduced to detect Yi characters,in which the Omni-dimensional Dynamic Convolution(ODConv)is combined with the ResNet-18 feature extraction module to obtain multi-dimensional complementary features,thereby improving the accuracy of Yi character detection.Then,the feature pyramid network fusion module is used to further extract Yi character image features,improving target recognition at different scales.Further,the previously generated feature map is passed through a head network to produce two maps:a probability map and an adaptive threshold map of the same size as the original map.These maps are then subjected to a differentiable binarization process,resulting in an approximate binarization map.This map helps to identify the boundaries of the text boxes.Finally,the text detection box is generated after the post-processing stage.In the recognition stage,an improved lightweight MobileNetV3 framework is used to recognize the detect character regions,where the original Squeeze-and-Excitation(SE)block is replaced by the efficient Shuffle Attention(SA)that integrates spatial and channel attention,improving the accuracy of Yi characters recognition.Meanwhile,the use of depth separable convolution and reversible residual structure can reduce the number of parameters and computation of the model,so that the model can better understand the contextual information and improve the accuracy of text recognition.The experimental results illustrate that the proposed method achieves good results in detecting and recognizing Yi characters,with detection and recognition accuracy rates of 97.5%and 96.8%,respectively.And also,we have compared the detection and recognition algorithms proposed in this paper with other typical algorithms.In these comparisons,the proposed model achieves better detection and recognition results with a certain reliability.

Eruptive xanthomas in a patient with severe hypertriglyceridemia:A case report

BACKGROUND Xanthomatosis,a metabolic disorder causing yellow growths(xanthomas),poses challenges in lipid metabolism.This case study introduces the first documented instance within China's Yi population,emphasizing the need to explore dietary habits and treatment strategies tailored to this specific community.CASE SUMMARY Xanthomatosis is a metabolic disorder where lipid metabolism goes awry,resulting in the development of yellowish growths called xanthomas.A male patient,47 years of age,from China's Yi population,who is obese,visited our dermatology clinic complaining of widespread,non-painful rashes that have been present for two weeks.The patient works as a chef and has a diet that frequently includes oily and greasy foods.This case represents the initial documentation of xanthomatosis within the Yi population in China,offering a theoretical foundation for understanding dietary patterns and treatment options specific to the Yi community.CONCLUSION The first report of xanthomatosis in the Yi population in China lays a theoretical foundation for understanding Yi dietary patterns and treatment.

Beyond Gender Perspectives:A More Comprehensive Examination of Yang Yi’s Translation of Wuthering Heights

The renowned translator Yang Yi passed away in 2023.Many scholars argue that,influenced by their biological gender,female translators often employ translation methods in adherence to feminist translation or reflect characteristics typical of female translators.This study examines the translation of Wuthering Heights by Yang Yi,focusing on whether there is a definite influence of gender on translator behavior.While existing literature primarily analyzes Yang Yi’s work through a feminist lens,this research takes a broader approach.By considering the translator’s social background and translation practice,this paper challenges the assumption that her work strictly aligns with feminist translation theories.Instead,this study emphasizes the importance of considering diverse factors when interpreting translated works,moving beyond a singular gender-based standpoint.

Textual research on Xu Chunfu's life

Xu Chunfu was a famous medical expert in the Ming Dynasty, who authored the Gu Jin Yi Tong Da Quan and the Yi Xue Zhi Nan Jie Jing Liu Shu. This paper uses the Xu family genealogy, literature catalog, historical records to study the Xu family’s life and deeds. Xu Chunfu was born in the second year of the Jiajing reign of the Ming Dynasty (1523) and passed away in the 24th year of the Wanli reign of the Ming Dynasty (1596). He served as an official in the Tai Hospital for about 20 years. His work Gu Jin Yi Tong Da Quan was written around the 43rd year of the Jiajing reign of the Ming Dynasty (1556), with a lower limit of the fifth year of the Longqing reign of the Ming Dynasty (1571), and the initial engraving time was not earlier than the eighth year of the Wanli reign of the Ming Dynasty (1580). This paper corrects the shortcomings and errors in previous research, and provides a comprehensive and systematic examination of Xu Chunfu’s life and works.

Spatiotemporal evolution of ecosystem service value and topographic gradient effect in the Da-Xiao Liangshan Mountains in Sichuan Province,China

The Da-Xiao Liangshan mountains are critical ecological function areas and essential ecological barriers in the upper reaches of the Yangtze River in China.This study selected a total of six periods of land use land cover(LULC)data from 1995 to 2020,to estimate the ecosystem service value(ESV)and analyzed its spatiotemporal evolution and topographic gradient divergence.The results showed that:(1)The ESV increased by 1.1 billion yuan,with an increase rate of 1.47%from 1995 to 2020.Two time periods,2005–2010 and 2015–2020,showed more significant increases than other periods.(2)The elevation and slope of mountainous areas determine the type of land use and further influence the spatial pattern of ESV.(3)Although woodland and grassland are the main land use types of the study area(more than 90%),the hydrological regulation function of the water area partially compensated for the impact of the encroachment of the built-up area on the ESV of grassland.(4)The spatial distribution of ESVs showed an inverted V-shaped characteristic as the topographic gradient increased,with the dominant position being the 5th topographic gradient zone.Finally,this study provided relevant recommendations for ecosystem protection and optimization.The findings of this study clarified the influence of topographical factors on the spatial differentiation of ESV and provided novel insights into ecosystem protection.

Rethinking Yi’an(Medical Cases)as a Tool for Narrative Medicine in China

When narrative medicine(NM)was introduced into China,traditional Chinese medicine scholars found that the core concepts advocated by NM are manifested in Chinese yi’an.But why NM echoes with ancient Chinese yi’an?How can we better integrate NM into Chinese medical practices?To answer those questions,this article first investigates how NM establishes itself as a remedy to biomedicine by taking traditional healing models including TCM as its ideal Other.Then,the narrative traditions of both case histories and yi’an are examined respectively.This article argues that NM is searching for a lost tradition of narrative case histories,but yi’an functions as a living tradition of TCM.The Parallel Chart in NM,designed as a complement to the dehumanized hospital chart,is still based on a dichotomy of science and art and a conflictual doctor-patient model.But yi’an exemplifies the holistic and humane healthcare that NM hopes to achieve.A comparison of both genres also inspired us to rethink the genre of yi’an in NM.Thus,it is concluded that yi’an should be viewed as an epistemic genre integrating individualization and generalization,a bridge linking medicine and literature.And narrative yi’an can well serve as a tool for NM in China.It is also proposed that a thick description of yi’an be encouraged to further promote a pluralistic NM in China.

Research on the Ecological Wisdom of Traditional Dwellings of the Liangshan Yi Nationality Based on Regional Climate

As a typical building with ethnic and regional characteristics in southwest Chi-na, its construction skills contain rich local ecological wisdom. The detailed analysis of the climatic and geomorphological features of the Liangshan Yi nationality area shows that the thermal mass effect is the first choice for the passive adjustment strategy of residential dwellings. This study focuses on the typical representatives of traditional dwellings in Meigu County, analyzing the wisdom of ecological construction to improve the thermal mass effects of res-idential buildings at the macro (village), moderate (courtyard), and micro (building unit) levels. Based on this analysis, the study summarizes the “genetic factor library” of the ecological construction mode of traditional Yi residential dwellings. Finally, the measured data of the residential thermal environment and the simulation data of Ecotect software are used to study and judge the logic behind its ecological construction wisdom. The results show that the tradi-tional dwellings of the Yi nationality in Liangshan have six aspects of local en-vironmental knowledge to improve the thermal mass effects performance of buildings. The winter thermal environment of the house is comfortable, and the heat is sufficient;Rammed earth materials in residential buildings have more potent, powerful, and robust thermal mass effects performance than stone slabs and wooden boards.

The Research of the Relationship Between Yangming’s Yixue and His Xinxue

Yangming’s Yixue had been developed several times in his life since originated in Longchang.Yangming’s Yixue and his Xinxue are both sides of the same corn.The Yangming’s Yixue can be roughly divided into two periods.There were the early and middle period of Yangming’s Yixue,which is intended to explain the principles of Yi Zhuan(《易传》)with the theory of Xinxue.The finish of Yangming’s Yixue was a second stage in Yangming’s later years.From the perspective of form and content,there are differences that cannot be ignored between Yangming’s early and middle period and his later years.In the first stage of Yangming’s study,the“Virtuousness”(贞)in Book of Changes is the principle and nature in university.In the later period,Yangming had not focused on interpreting the“Yi Zhuan”,but on the interpretation of ZhouYi’s(《周易》)principles to supplement the connotation of the propositions of Xinxue.This article intends to understand the relationship between Yangming’s Yixue and his Xinxue by dividing the different stages of Yangming’s Yixue firstly.Then by focusing on the influence of Yangming’s later years’Yixue on his Xinxue,we can observe the relation between his Yixue and Xinxue.
