Abstract： Objective This paper aims to quantify the sentence alignment scores of low-resource parallel corpora to obtain high-quality parallel corpora, improving machine translation performance. Methods We propose NeuroAlign, a neural network-based unsupervised sentence embedding method for scoring bilingual parallel sentence alignment. Parallel sentence pairs are embedded into the same vector space, and alignment scores for given candidate sentence pairs in the parallel corpus are calculated. Based on these scores, low-scoring sentence pairs are filtered out, resulting in high-quality bilingual parallel corpora for low-resource languages. Results In the BUCC2018 parallel text mining task, the F1 score can be improved by 0.5-0.8. In the CCMT2021 low-resource language neural machine translation task, the BLEU score can be improved by 0.1-10.9. The sentence alignment scores can approach human evaluation. Limitations Due to the scarcity of low-resource bilingual parallel corpora, research has not been conducted on language pairs other than Tibetan-Chinese, Uyghur-Chinese, and Mongolian-Chinese. Conclusions This method can be effectively applied to sentence alignment scoring for low-resource language machine translation parallel corpora, improving the quality of the data source, and thereby enhancing machine translation performance.

Abstract： Purpose To evaluate the coverage and accuracy of author identification number (author ID) of the major bibliographic databases and to assess whether they could be directly used in empirical research.
Methods The ground truth data set consists of articles from 825 Chinese scientists. The coverage, accuracy, and robustness of each author ID are calculated by retrieving and collecting the IDs of scientists and their respective publication information in the bibliographic databases. The validity of the author IDs for empirical research is assessed by replicating a top journal empirical article using the data collected through author IDs.
Results First, WOS, Scopus, AMiner, and OpenAlex can retrieve more than 90% of Chinese scientists’ identifiers, while ORCID’s coverage is less than 50%. Second, the accuracy of Scopus is the highest at 85.2%, and the accuracy of OpenAlex is the lowest at only 51.2%. Third, directly using the publication data collected through author IDs for empirical research will introduce non-negligible bias.
Limitations The ground truth data set is limited, because it is mainly composed of young scientists, and lack scientists from social sciences and humanities.
Conclusion At present, the author identification number of the major databases cannot be directly applied to the empirical research of large-scale data. A standardized information platform for scientists’ publications is needed to overcome the author-name disambiguation problem.

Abstract： Objective To analyze some of the characteristics of papers retracted in batch by Hindawi journals. The aim is to provide a reference for Chinese scientific and technical journals on how to deal with the systematic manipulation of the publication process.
Methods Retraction statements and retracted papers were obtained from the Hindawi XML corpus. Based on the Web of Science core collection, we analyzed the author affiliations and citations of the retracted papers.
Results Hindawi journals retracted a total of 11,371 papers between November 16, 2022 and March 20, 2024. The majority (74.7%) of these retracted papers were published in 2022, with an average of 46 days from submission to acceptance, 77 days from submission to publication, and 526 days from publication to retraction. The 50 institutions in mainland China with the highest number of publications in the same period were involved in publishing 18.6% of the retracted papers.
Conclusion Batched retraction of papers involving systematic manipulation of the publication process is a practice by publishers to combat “paper mills”. Although most retracted papers had authors from mainland China, the authors of retracted papers cannot be considered representative of Chinese researchers. Chinese scientific journals should avoid manipulation of the publication process due to editorial incompetence, and research institutions should strengthen education on research integrity to prevent Chinese authors from being involved in similar incidents.

Abstract： This paper aims to leverage the advancements in General Computer Control (GCC) to improve the efficiency and effectiveness of risk management operations in financial institutions. Specifically, we introduce an LLM-based Robotic Process Automation (RPA) framework designed to enhance front-line employee work, adapt to the specific needs of financial institutions, and automate tasks requiring minimal cognitive effort. To demonstrate the effectiveness of our proposed framework, stress testing, a common task for risk management department, is used as a case study. The results show that the RPA system can improve efficiency, reduce costs, and minimize errors, all without significantly altering the existing workflow. Moreover, to address customer information security and prompts copyright protection issues, a storage method that separates the server from the client is used. Finally, empirical evidence implies that even models with weaker capabilities can achieve the desired work objectives when guided by detailed prompts.

Abstract： The expanding applications call for novel new-generation wide-bandgap semiconductors. Here, we show that a compound only composed of the ordinary elements Na and Cl, namely three-dimensional NaCl2 crystal, is a wide-bandgap semiconductor. This finding benefits from the breaking of conventional stoichiometry frameworks in the theoretical design, leading to the discovery of three-dimensional XY2 (X = Na, Li, K; Y = Cl, F, Br, I) crystals, with covalent bonds of Y pairs inducing the wide bandgap from 2.24 to 4.45 eV. Crucially, such an unexpected NaCl2 crystal was successfully synthesized under ambient conditions. The unconventional stoichiometric strategy with other chemical elements potentially yields more wide-bandgap semiconductors, offering the capability for bandgap tuning. These unconventional stoichiometric materials may also exhibit superconductivity, transparent inorganic electrides, high-energy-density, and beyond.

Abstract： Interpersonal invisibility refers to the intentional or unintentional disregard of individuals in social interactions, resulting in cognitive, emotional, and behavioral disengagement or reduced engagement. Essentially, it represents an implicit form of interpersonal devaluation and exclusion. Interpersonal invisibility is closely linked to social hierarchy, with individuals of lower social hierarchy being more susceptible to experiencing it. Theoretical frameworks such as sociocultural mechanisms, the status hypothesis, affordance-management theory, and intersectional invisibility theory serve as crucial perspectives for explaining this phenomenon. Future research should further refine the conceptualization and measurement of interpersonal invisibility, deepen theoretical investigations into its effects on individuals of lower social hierarchy, explore the interaction between the social hierarchy of both interactants, address and mitigate the negative consequences of interpersonal invisibility, and examine its unique effects within the context of Chinese culture.

Abstract： ChatGPT has sparked a transformation in library construction and evaluation standards, as well as in the methods of library services, gradually advancing innovation in the overall public cultural security strategy. ChatGPT contributes to the enhancement of library services, including intelligent recommendations, search capabilities, classification, translation, and editing, thereby enriching users’ three-dimensional and immersive perceptual experiences. But it also brings risks and challenges for libraries in terms of user privacy, information data, and ideology. For this reason, it is necessary to optimize the development path to enhance the library’s intelligent service and security guarantee. Firstly, it entails promoting technological innovation and optimizing infrastructure to establish a robust intelligent service system for libraries, thereby dismantling the technological hegemony controlled by capital. Secondly, it involves constructing a data supervision platform to enhance intelligent services. This includes promoting the development of a collaborative mechanism for the diverse construction of libraries and defending the primary ideological position of socialism in our country. Thirdly, it is imperative to nurture a skilled workforce and cultivate the next generation. Coordinating efforts from various sources collaboratively stimulates the learning effectiveness of individuals, fostering a team of technologically innovative talents with unwavering ideals and the courage to pioneer breakthroughs.

Abstract： Perleididae is a group of stem neopterygian fishes known only from the Triassic. Here, we report the discovery of a new perleidid, Teffichthys wui sp. nov., based on six wellpreserved specimens from the late Smithian (Olenekian, Early Triassic) marine deposits of Jurong, Jiangsu and Chaohu, Anhui, China. This new discovery documents the third and youngest species of Teffichthys, which is slightly younger than the Dienerian (Induan) T. elegans from Guizhou and the early Smithian T. madagascariensis from Madagascar. The new species shows diagnostic features of Teffichthys (presence of a spiracular, 38–41 lateral line scales, and no more than three epaxial rays in the caudal fin) but differs from T. madagascariensis and T. elegans in some autapomorphies (e.g., a horizontal opercle/subopercle contact and smooth scales with a nearly straight posterior margin). The diagnostic features for the genus Teffichthys and the family Perleididae are emended based on detailed comparisons of the new taxon with other perleidids. The phylogenetic relationships of perleidids with other stem neopterygians are discussed using a cladistic approach, and the results provide new insights into the phylogeny and classification of main stem neopterygian clades.

Abstract： To investigate the characteristics of the fungal community and potential key pathogens, ITS rDNA gene amplicon sequencing technology and FUNGuild analysis were used to study the fungal community composition, network characteristics and ecological function groups in rotting tubers of Dioscorea. sp. Additionally, potential pathogenic fungi were isolated and identified. The results were as follows: ( 1 ) In rotting tubers of Dioscorea sp., the dominant phylum was Ascomycota, and prevalent fungal genera included Penicillium, Colletotrichum, Fusarium, Talaromyces, Clonostachys, etc. The fungal molecular ecological network exhibited a clear modular structure with a high ratio of positive correlation edges (99.33%), suggesting that positive cooperation was strengthen between different fungi. ( 2 ) FUNGuild analysis indicated that 10 guilds were highly correlated with yam tuber rot. Among these guilds, the relative abundances of dung saprotroph-undefined saprotroph-wood saprotroph and endophyte-plant pathogen were 33.74% and 23.64%, respectively, and the representative genera were Penicillium and Colletotrichum, respectively. Additionally, three guilds were related to both plant pathogen and wood saprotroph, and occupied 13.67% of the ecological functional groups. Moreover, Fusarium was representative genus of all three guilds. Traits analysis showed that some fungi (Penicillium, Fusarium, etc.) in the fungal community were probably invovled in yam tuber rot. ( 3 ) A total of 22 strains were isolated and belonged to 6 genera, including Fusarium ( 9 strains ), Penicillium ( 5 strains ) and Aspergillus ( 4 strains ), etc. This study provides an important reference for understanding the pathogenesis of tuber rot in Dioscorea sp., and for the selection of appropriate pesticides and biocontrol microbes.

Abstract： The green leaves, variegated leaves and yellow leaves of Yulania denudata with variegated leaf were used as experimental materials. The anatomical structure and photosynthetic characteristics of three types of leaves were compared from the aspects of photosynthetic pigment content, leaf anatomical structure and light response curve, the factor of photosynthetic characteristics of Y. denudata with variegated leaf was revealed from anatomy. The the result of research as follows: (1) The yellow leaf spots of Y. denudata with variegated leaf is chlorophyll-type leaf spots formed by the decrease of chlorophyll content due to the abnormal structure of chloroplasts. (2) The structure of the thylakoids in the yellow region of the flower and leaf Y. denudata with variegated leaf was abnormal, and ATP synthesis was blocked, which hindered the progress of photosynthesis. (3) The anatomical structure showed that the palisade tissue of the green leaf was developed, the chloroplast integrity and pigment content were higher than that of the variegated leaf and the yellow leaf, and the net photosynthetic rate was higher. (4) There was a significant difference in the maximum net photosynthetic rate and light saturation point between the green leaf and the variegated leaf, and the green leaf can withstand a wider range of bright light than the variegated leaf. This study further elucidates that that the chloroplast structure of Y. denudata with variegated leaf affected its photosynthetic characteristics, and the results provided references for the breeding of fine varieties.

Abstract： In order to reveal the albino mechanism of gold-coloured mutant leaves of Cyclobalanopsis gilva, a naturally-occurring leaf-color mutant was used as experimental materials, and the metabolome and transcriptome of mutant leaves and normal green leaves were analyzed by UHPLC-Q Exactive HF-X and high-throughput RNA sequencing, respectively. The results were as follows: ( 1 ) 257 and 357 significantly changed metabolites ( SCMs ) were respectively identified under the positive ion mode and the negative ion mode. Compared with green leaves, the content of some flavonoids such as quercetin, leucoyanidin, myricetin and their derivatives (pyranodelphinin A, isorhamnetin 3-glucuronide, etc. ) increased significantly in mutant leaves, but the content of chlorophylls and carotenoids decreased significantly. ( 2 ) A total of 4 146 differentially expressed genes (DEGs) were detected, of which 1 711 were up-regulated and 2 435 were down-regulated. ( 3 ) KEGG enrichment analysis showed that SCMs and DEGs were mainly enriched in photosynthesis, porphyrin and chlorophyll metabolism and flavonoid biosynthesis. The research results indicate that inhibition of chlorophyll synthesis, chloroplast developmental abnormalities and promotion of flavonoid synthesis were the main factors driving the golden leaf coloration in the mutant C. gilva. In addition, the genes of the MYB and bHLH families were significantly up-regulated in mutant leaves, confirming these two types of transcription factors were involved in regulating flavonoid biosynthesis. This study provided new molecular insights into the phenomenon of leaf etiolation, and also provided reference for exploring leaf color-related functional genes and breeding of landscape plant.

Abstract： The stability of phyllosphere microbial community is closely related to plant health. In order to understand the microecological characteristics of tobacco leaves infected with wildfire disease, community structure and diversity of phyllosphere microbiome in diseased spots and healthy tissues of tobacco leaves with different degrees of disease using high-throughput sequencing technology in this paper. The results showed that the dominant microorganisms in diseased and healthy tissues were Proteobacteria and Ascomycota, and their relative abundance in diseased tissues was significantly higher than that in healthy tissues. The dominant genera were Pseudomonas, Pantoea, Alternaria, Plectosphaerella and Conocybe, and only the relative abundance of Pseudomonas in diseased tissues was significantly higher than that in healthy tissues. The diversity and richness of bacterial communities in diseased spots were higher than those in healthy tissues, and the diversity index showed a trend of decreasing and then increasing with the increase of the degree of disease, and the richness index showed a trend of increasing and then decreasing. The richness and diversity index of fungal communities in diseased spots showed a trend of increasing and then decreasing with the increase of the disease degree, and the diversity and richness of fungal communities in diseased spots of mildly and moderately diseased leaves were higher than that in healthy tissues, but the diversity and richness of fungal communities in heavily diseased tissues were lower than those in healthy tissues. Gene functional information and relative abundance of bacteria in diseased spots and healthy tissues are generally similar, primarily related to metabolism, genetic information processing and environmental information processing. The dominant functional taxa of fungi were plant pathogen, animal pathogen-endophyte-plant pathogen-wood saprotroph, undefined saprotroph, wood saprotroph and plant pathogen-wood saprotroph. The results provide a reference for the understanding of evolutionary pattern of tobacco wildfire disease and characterization of the phyllosphere microbial community.

Abstract： Bacterial wilt is a devastating soil-borne disease in tomato (Solanum lycopersicum) production. The pathogenic species are complex and tend to have a variation, while mlo caused by the recessive mutation of MLO genes has a broad-spectrum resistance. The previous study suggested that Slmlo1/6 may be involved in the resistance response to bacterial wilt in tomato. In order to further study the gene function of Slmlo1/6 in tomato bacterial wilt resistance, the genetic mutant plants were created by CRISPR/Cas9 technology and their phenotypes were identified followed. The results were as follows: ( 1 ) First, gRNA sequences of SlMLO1/6 were designed and assembled with the U6 promoters, then U6-gRNA1/6 fragments containing highly effective targets were ligated to CRISPR vector of pBGK via restriction enzyme Bsa I digestion, to construct the two-gene fusion knockout vector of pBGK-SlMLO1/6. The recombinant plasmid of pBGK-SlMLO1/6 was transformed into Escherichia coli DH5α competent cells and positive monoclonal clones were selected via plate cultivation. Using Agrobacterium tumefaciens GV3101 strains-mediated genetic transformation and resistance screening to hygromycin, a total of 9 edited tomato plants were obtained with the PCR and sequencing validation. ( 2 ) Target region sequencing showed that M2 and M8 plants had the 177 bp and 7 bp deletion of SlMLO1, respectively, M7 had the 12 bp deletion of SlMLO6, and M9 had a single base T insertion of SlMLO6. Except for 4 single gene homozygous mutants above, the other mutations were heterozygous. ( 3 ) RT-qPCR showed that compared with the wild type plant, SlMLO1/6 gene expression of the mutants was significantly decreased, especially M2, M7, and M8 plants. ( 4 ) Phenotypic identification indicated that SlMLO1/6 may be tomato bacterial wilt susceptibility genes. In a word, the knockout vector is successfully constructed for broad-spectrum resistance MLO genes and tomato transformation is also achieved. Further, a few homozygous gene edited plants acquire resistance to bacterial wilt to some extent. Amino acid deletion and frameshift mutation may be two crucial reasons for the gene function change of Slmlo1/6 in resistance. The results provide a theoretical basis and genetic engineering materials for the gene function study in resistance to bacterial wilt and disease resistance breeding in tomato.
