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.

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.

润滑剂YI对聚氯乙烯塑料流变性能的影响

采用毛细管流变仪，考察润滑剂ＹＩ用量对ＰＶＣ流变性能的影响。实验表明，流体非牛顿指数ｎ＜１，并随ＹＩ用量增加而下降。ＹＩ使ＰＶＣ熔体粘度大幅度减少，在硬质ＰＶＣ中，ＹＩ用量在０．６～１．０ＰＨＲ作用最明显；在软质ＰＶＣ中，当剪切速率γ＞５００ｓ－１时，少量ＹＩ就能使熔体粘度下降。并测定了不同ＹＩ用量ＰＶＣ的流动活化能，随ＹＩ用量增加，Ｅη略有下降。

论宣王中兴与王官诗学的裂变

《大小雅》中存有大量周宣王朝诗,这与宣王中兴有关。“雅中之颂”“‘变雅’作矣”两组感情色彩迥异的诗同时存在于诗文本中,是宣王时期政治社会生态的折射。宣王朝诗文本的编辑活动,以服务礼乐仪式为目的,但客观上导致了诗歌讽谏功能的长足发展,进而引发了王官诗学的裂变。从此,诗教由乐教附庸而趋向独立,并朝着注重德教的伦理化方向发展。

Dialogic Function of Denial Resource in Political Commentaries: A Perspective of Appraisal

Appraisal is a major kind of discourse semantic resources construing interpersonal meaning, which includes three subsystems: attitude, engagement and graduation. Engagement resources are linguistic resources of inter- subjective positioning,through which writers or speakers open up or close down dialogic space for putative reader and try to align or disalign readers on the ground of solidarity. This study applies engagement system to analyze political commentaries. It focuses on the denial resources in detail. In political commentaries, by using denial resources, the commentator invokes, and then directly rejects different opinions or beliefs the putative readers may have. Through strategy of dialogic resources, commentators try to make up for disalignments caused by denial and form the grounds for solidarity.

Casual sex and concurrent sexual partnerships among young people from an Yi community with a high prevalence of HIV in China

Liangshan Prefecture in Sichuan province, China, has a high prevalence of HIV infection, which is reflective of a change in the mode of transmission from injection drug use （IDU） to heterosexual intercourse. However, few studies focus on HIV-related heterosexual risk behaviours among the majority Yi population. The objectives of this study were to explore the characteristics of an egocentric sexual network and estimate the prevalence of casual sexual behaviour. Yi villagers （n= 108）, aged 15-35 years, who reported having had sex within the previous year were interviewed as to their sexual behaviours and networks. In-depth interviews and focus group discussions provided supplementary information on sexual norms. Logistic regression analysis was used to calculate unadjusted odds ratios （ORs） and 95% confidence intervals （CIs）. Most of the respondents reported having had casual sex at some time in their life, and 66.7% reported multiple sexual partnerships. Only 21.3% reported ever having used a condom. During the study year, a total of 137 partners were involved in 153 sexual partnerships. Among the reported sexual partnerships, 67.3% originated from a casual sexual relationship. For network members in components of size ≥3, 56,9% were involved in concurrent sexual partnerships. Having never been married （OR： 2.11; 95% CI： 1.03-4.33） and younger age （OR： 0.89; 95% CI： 0.83-0.95） were both associated with being in a component of size ≥3. Size （OR： 2.99; 95% Ch 1.17-7.66）, pair （OR： 0.54; 95% Ch 0.039-0.74）, the number of weak components of the egocentric sexual network （OR- 30.04; 95% Ch 6.47-139.46） and gender （OR. 0. 19; 95% Ch. 0.06-0.67） were all associated with being in concurrent sexual partnerships. HIV-related interventions for the Yi ethnic minority in Sichuan province must therefore address concurrent sexual partnerships and promote condom use.

Trends of Overweight and Obesity in Yi People between 1996 and 2007:An Yi Migrant Study

Objective To evaluate trends of overweight and obesity prevalence between 1996 and 2007 in Yi farmers and Yi migrants.Methods An Yi migrant study was conducted in Liangshan Yi Autonomous Prefecture,Sichuan Province,China from 1996 to 2007.Data were collected with identical methods,including standardized questionnaire and body measurements.Results Age‐ and sex‐specific body mass index （BMI） significantly increased from 20.02 in 1996 to 22.36 in 2007,among Yi farmers,which was significantly different from those among Yi migrants （23.67 in 2007 and 20.90 in 1996） （P0.05）.Prevalence of obesity rose from 1.21 % in 1996 to 4.55 % in 2007 （OR=1.15,P0.001） in Yi migrants,while that in Yi farmers from none in 1996 to 0.12 % in 2007 （P0.05）.Prevalence of overweight rose significantly to 26.24 %in 2007 from 17.24 % in 1996 （OR=1.06,P0.001） in Yi migrants,while that in Yi farmers from 1.29 % in 1996 to 4.45 % in 2007 （OR=1.14,P0.001）.Yi migrants appeared to have a 5.52‐fold higher risk ondeveloping overweight and obesity than Yi farmers have.Conclusion The Yi migrants had a steeper increase of overweight with year and consequently caused more obesity.Change in lifestyle may contribute most likely to higher prevalence of overweight and obesity in Yi migrants.

SOD and MDA in organs were determined, and pathological changes in pancreas were observed.RESULTS As compared with control group, the serum level of amylase (734U/L vs 2783U/L) and MDA (7.8nmol/ml vs 14.8nmol/ml) in Chinese medicine group were decreased on day 7 (P＜0.05), while SOD increased significantly (281nU/ml vs 55nU/ml, P＜0.01), and similar changes occurred in MDA and SOD in organs, especially in the pancreas; the pathological changes in the pancreas were alleviated as well.CONCLUSION 'Qing Yi Tang' is effective in clearing OFRs and alleviating pathological changes in ANP.

Body Mass Index and Hypertension Hemodynamic Subtypes in Yi Farmers and Migrants

Objective To examine the relationship between overweight or obesity and the risk of the various hypertension hemodynamic subtypes in Yi farmers and migrants. Methods A cross-sectional study of 2 358 Yi farmers and 2 392 Yi migrants was carried out in the Liangshan Yi autonomous prefecture, Sichuan, China in 2007. Results The standardized prevalence of overweight in female Yi farmers （6.22%） was higher than in males （3.25%）, whereas in Yi migrants 32.56% of males and 28.78% of females were overweight. The standardized prevalence of obesity was 0 and 0.62% in male and female Yi farmers, compared to 3.91% and 5.57% in male and female Yi migrants, respectively. For both genders the standardized prevalence of ISH, IDH, and SDH was higher in Yi migrants than Yi farmers. Overweight and obese Yi men and women had a higher risk for IDH and SDH （P〈O.002） than non-overweight/obese individuals. However, an association of overweight or obesity with ISH was observed only in men. Conclusion Yi migrants have substantially higher proportion of overweight and obese individuals, as well as individuals affected by ISH, IDH, and SDH, than do Yi farmers. Overweight and obesity are significant risk factors for the development of hypertension in Yi people.

Influence of social capital on the livelihood strategies of farmers under China's rural revitalization strategy in poor mountain areas: A case study of the Liangshan Yi autonomous prefecture

Social capital in the form of social resources or social networks is one of the most important livelihood capital of farmers, which can increase the labor productivity of poor households and increase income. It is important to explore the reasons underlying the livelihood strategy choices of farmers from the perspective of social capital under China’s rural revitalization strategy. In this study, the Liangshan Yi Autonomous Prefecture, a povertystricken mountainous area in southwestern China, was selected as the case study area, and multivariable linear regression models were constructed to analyze the influence of social capital on livelihood strategies.The results are as follows:(1) Individual social capital had a positive effect on non-agricultural livelihood strategies. On average, with a one-unit increase in individual social capital, the ratio of farmers’ nonagricultural income to total productive income(Income_Rto) increased by 0.002% and 0.062%,respectively. Collective social capital, with the Peasant Economic Cooperation Organization(PECO) as the carrier, had a negative effect on the non-agricultural livelihood strategies of farmers;on average, with a oneunit increase in PECO, Income_Rto decreased by approximately 0.053%. However, this effect was only significant in the river valley area.(2) The income differences among the different livelihood strategy types were explained by the livelihood strategy choices of farmers. As non-agricultural work can bring more benefits, the labor force exhibited one-way migration from villages to cities, resulting in a lack of the subject of rural revitalization. It is necessary to implement effective measures to highlight the role of PECO in increasing agricultural income for farmers. Finally,based on the above conclusions,policy recommendations with respect to livelihood transformation of farmers and rural sustainable development are discussed.

Commentary on:“Facilitating transparency in spinal cord injury studies using data standards and ontologies”

Commentary Most would agree that providing comprehensive detail in scientific reporting is critical for the development of mean- ingful therapies and treatments for diseases. Such stellar practices 1） allow for reproduction of experiments to con- firm results, 2） promote thorough analyses of data, and 3） foster the incremental advancement of valid approaches. Unfortunately, most would also agree we have far to go to reach this vital goal （Hackam and Redelmeier, 2006; Prinz et al., 2011; Baker et al., 2014）.
