Huanma paper-cut is the representation of the first batch of provincial intangible cultural heritage masterpieces of Sichuan province. In recent years, Huanma Town in Cangxi County of Sichuan Province has continuously explored and trans⁃ formed traditional techniques into a cultural industry, seeking a market for the development of Huanma paper-cutting industry and realizing the transformation of the industrial structure of“prospering the town with culture and promoting literature with classics”. At present, Huanma’s paper-cutting inheritance work faces problems such as insufficient follow-up, fewer papercut inheritance craftsmen, lack of in-depth theoretical research and deviations in development positioning. In the period of rural revitalization, the protection project of Huanma paper-cut should start from improving the“intangible cultural heritage”man⁃ agement mechanism, cultivating and protecting the inheritors of paper-cutting skills, increasing the promotion of intangible cul⁃ tural heritage, creating a market brand of paper-cutting culture, and strengthening the construction of paper-cutting schoolbased courses, etc. Aspects of systematic construction, so as to promote its sound development.

Objective To establish a simple and rapid paper-based extraction method for human papilloma virus (HPV) DNA and to evaluate the method. Methods The plasmid containing HPV type 16 gene fragment was employed as the test subjects, and then 6 different paper materials were compared and selected by ultraviolet spectrophotometry and real-time fluorescence quantitative PCR (qPCR). Then, according to the efficiency of nucleic acid extraction and the optimal binding area, a convenient paper strip was designed. Finally, the designed paper strip was applied to extract HPV DNA from 18 clinical cervical exfoliated cell samples (13 positives and 5 negatives), with its performance being evaluated after comparing with the conventional boiling method. Results The qualitative filter paper with a nucleic acid binding zone of 2 mm×10 mm could successfully extract HPV DNA from clinical cervical exfoliated cells. When this test strip was used for DNA extraction, all the 13 high-risk HPV positives were successfully detected out of the 18 clinical samples, which was consistent with the results of the conventional boiling method. In addition, the extraction time of the test strip was less than 1 min for each sample, with a detection limit of 8×102 copies/mL and relative standard deviation of 1.15%. Conclusion Our paper-based rapid extraction for HPV DNA does not require pipetting, heating and centrifugation, and the eluent can be directly used as the PCR template for amplification, which greatly simplifies the extraction process of HPV DNA from clinical cervical exfoliated cell samples.

With the development of science and technology,people need to access a large number of scientific and technological information quickly,and scientific paper is one of the main ways to carry scientific and technological information.As an important part of scientific paper,abstract is an effective tool for readers to retrieve literature.Therefore,the quality of abstract affects the retrieval rate of paper directly.However,due to the lack of writing experience,the quality of abstracts written by many authors is not high.Automatic generation of summary for scientific paper can help the author grasp the important content of paper more effectively,so as to write high-quality abstract.At the same time,the automatically generated abstract can also control the number of words in the abstract,which can bring more content to readers and help them understand the paper better.Generating automa-tic summarization for scientific paper can help author write abstract faster,which is one of the research contents in automatic summarization.Compared with common news document,scientific paper has the characteristics of strong structure and clear logical relationship.As far as the mainstream abstractive summarization such as encoder-decoder model is concerned,it mainly consi-ders the serialized information in the document,and rarely explores the text structure information in the document.For this reason,according to the characteristics in scientific papers,this paper proposes an automatic summarization model based on the hie-rarchical structure of "word-section-document",which uses the association between word and section to enhance the level of text structure and the interaction between levels,so as to screen out the key information in scientific paper.In addition,a context gate unit is extended to update the optimized context vector,thus capturing context information more comprehensively.The experimental results show that the proposed model can effectively improve the performance of the generated summarization in the ROUGE evaluation method.

Traditional paper dyes are easy to fade under photothermal conditions, in contrast. waterborne organic pigments have excellent tinctorial strength and high light and weather resistance, which can meet the requirements of highend paper yarn to coloring efficacy and light fastness of the colorants. However, the lack of chemical and hydrogen bonds between organic pigment particles and plant fibers, and the pigments are difficult to fix in the structure of the paper. In this study, cellulose nanofibers (CNF/TOCNF) were used as the primary skeleton network and carboxymethyl cellulose (CMC) macromolecules were used as the secondorder reinforcement network, together construct a multilevel gradient network to enclose and fix organic pigment particles. The dispersion and fixation of the pigment particles are realized by double coating. The results show that the coloring efficacy and colorfastness of the paper yarn base paper can be improved significantly by using the gradient network to fix the pigment particles, and has a positive effect on improving the strength and roughness of the paper. This study has an important role in solving the problem of coloring technology in the production of high-end paper yarn. [ABSTRACT FROM AUTHOR]
