Empowering cultural sharing with digital intelligence technology and focusing on solving the problems of unbalanced and insufficient development in China's cultural field as well as the division of spiritual wealth is a practical path to build a modern Chinese civilization in line with the rapid development of digital technology and digital economy. While we have long emphasized the importance of cultural sharing. previous limitations in technical and market capacities have hindered our ability to realize this objective. The emergence of digital intelligence technology has provided a new impetus for the sharing of cultural production. distribution. circulation and consumption in science and technology. Since the 18th National Congress of the Communist Party of China (CPC), the pragmatic groundwork for leveraging digital and intelligent technologies to facilitate cultural sharing has been progressively refined and established. guided by the policies of the CPC and the state. This paper further investigates the intricate predicaments in the realm of digital cultural development. encompassing the elucidation of platform ownership structure, the navigation of social capital investment and financing risks, and the comprehensive governance of platforms. We revealed that the operation mechanism of cultural resources and spiritual wealth on the digital cultural platform still has a certain gap with the concept of cultural sharing, thus, increasing the threshold for rational allocation of cultural resources and equal sharing of cultural achievements, and exacerbating the mismatch of values and the polarization of spiritual wealth. Specifically, platform data tends to be monopolized, which is not conducive to the sharing of public spiritual wealth by all individuals: excessive profit-seeking in investment and financing in the cultural industry exacerbates the imbalance in the distribution of cultural resources: algorithmic discrimination in digital cultural communication results in disordered differentiation; and the "production-consumption nexus" in digital cultural consumption has aggravated the fragmentation of cultural enjoyment. While debates persist within the academic community regarding the public and private ownership of platforms and their data and the transfer of ownership. under the conditions of the socialist market economy with Chinese characteristics, digital platforms have evolved into important public infrastructure for the entire country and economic and social development due to their inherent natural monopoly. Compared with previous studies, this paper expands on the realization path of the digital cultural platform and its general data-sharing reform. Firstly, adhering to economic and social development laws and the inherent logic of platform enterprise evolution, this study proposes reforming and building a synergistic mechanism between platforms, government, and enterprises to cultivate new cultural enterprises: Secondly, it is to gradually build up a public ownership-based cultural economic foundation to realize fair distribution of cultural resources and equal sharing of cultural achievements. Gradually establishing a cultural economic foundation based on public ownership is essential for achieving fair distribution of cultural resources and equal sharing of cultural achievements, enhancing the universality of public cultural services and thus promoting the rationality of spiritual wealth distribution. Thirdly, this study advocates strengthening the comprehensive governance of algorithms and promoting the ubiquity of the circulation of public cultural products. Lastly, the establishment of a cultural sharing consortium is proposed to regulate, weaken, and even eliminate capital alienation in cultural consumption. Based on the principles of Marxist political economy, this paper points out some practical dilemmas of digital intelligence technology-enabled cultural sharing at the level of the cultural economic circulatory system. This study aims to provide beneficial explorations for the implementation of national cultural digitization strategy, and the inheritance and development of the new cultural mission. Moreover, it offers differentiated programmatic support for various digital cultural platforms to gradually evolve into collaborative and shared entities, to address the opportunities and challenges faced by culture and related data during platform reform and development in the current era.

The environmental assessment of bicycle travel in rail stations catchment areas is critical for promoting the efficiency and quality of bicycle feeder trips. Based on multi-source data from Baidu Street View, road network, and rail stations, the comfort, safety, convenience, and accessibility of bicycle riding environment evaluation indexes were selected. The DeepLabV3 + model and sDNA analysis were used to assess the bicycle travel environment of various types of roadways within the 1 500 m range influence region of the rail station, with Nanjing City serving as an example for empirical analysis. The results show that there are spatial differences in bicycle travel environment in the catchment area of the rail stations. The traffic-type roads have high travel accessibility and high sky visibility, but low bicycle access convenience. Although the accessibility of life roads is low, the convenience of bicycle access and green vision rate are high. Comprehensive roads indicators are relatively coordinated. [ABSTRACT FROM AUTHOR]

Objective To analyze the risk factors related to the development of adolescent myopia to identify the risk factors and protective factors, to provide basis for implementing prevention and control measures for adolescent myopia. Methods From September 2021 to April 2022, a questionnaire survey was conducted among junior and senior high school students in a middle school group in Chengdu by stratified cluster sampling, including personal basic information and risk factors related to the development of myopia. A total of 2 072 participants were included. SAS9.4 software was used for univariate analysis, and R4.2.3 software was used to analyze the statistically significant factors using multiple logistic regression. Results The results of univariate analysis showed that there were 15 factors including sex ( x² = 25.56, P < 0.001 ) age ( F = 62.11 . P < 0.001 ) and grade x² = 192.7 P<0.001) were significantly associated with myopia. The results of multiple logistic regression showed that among the 15 independent variables, seven variables including gender, grade, and frequency of doing eye exercises were statistically significant. The protective factors included doing eye exercises every day (OR=0.64, 95%CI: 0.42-0.98) and doing physical exercise for more than 1.5 hours (OR=0.52, 95%CI: 0.33-0.83). The risk factors included female students ( OR = 1.47, 95%CI: 1.20-1.81), average daily time of using electronic products > 5 hours to 7 hours ( OR = 3.1, 95%CI: 1.42-6.80), and average time of doing homework per day > 3 hours to 4 hours (OR = 1.57, 95%Cl / 1.16 - 2.12) Conclusion There are multiple risk factors related to the development of adolescent myopia.

【Objective】CMB1 gene plays an important role in the regulation of inflorescence structure and fruit ripening in plants, but the function and regulatory mechanism of CMB1 gene in pepper have been rarely reported. Therefore, the role of transcription factors related to the regulation of carotenoid synthesis and CMB1 gene in pepper was studied so as to provide a reference for pepper breeding.【Method】The coding sequences of CMB1 were cloned by the homology sequence method, and the expression patterns of CMB1 in fruits of red and yellow peppers with wrinkled skin at different development stages (green ripening stage, color change stage, mature stage) were analyzed by real-time quantitative PCR. 【Result】The ORF length of CMB1 gene was 732 bp in both red pepper and yellow pepper, encoding 243 amino acid residues. Sequence alignment showed that the mutation occurred at the 11th site of CMB1 base sequence, G mutated to T, resulting in amino acid sequence mutated from G (Glycine) to V (Valine). Bioinformatics analysis revealed that the CMB1- encoded protein of wrinkled skin red pepper had a molecular mass of 20 923.21, a theoretical isoelectric point of 5.59, an instability coefficient of 57.28, and a total mean hydrophilicity (gravimetric) index of -1.001. The CMB1-encoded protein of wrinkled skin yellow pepper had a molecular mass of 27 958.47, a theoretical isoelectric point of 7.10, an instability coefficient of 53.54, and a total mean hydrophilicity (gravimetric) index of -0.809. Both CMB1 of wrinkled skin red and yellow peppers were unstable hydrophobic proteins, both contained 38 phosphorylation sites, both were devoid of transmembrane structures and signal peptides, and both had typical MADS-box structural domains and K-box structural domains. Evolutionary tree analysis revealed that pepper CMB1 was most closely related to Solanaceae and most distantly related to Leguminosae. The results of fluorescence quantitative PCR showed that the expression of CMB1 increased sequentially in the three stages of green ripening, color change, and maturity of pepper fruits, and the expression of CMB1 in the three stages was significantly higher in wrinkled skin red pepper than in wrinkled skin yellow pepper.【Conclusion】Pepper CMB1 is a member of MADS-box, and its expression in pepper fruit is similar to that of carotenoid in pepper, suggesting that CMB1 is mainly involved in regulating the synthesis of carotenoid like capsanthin.

The experiment was to explore effect of different mulching materials on growth characters and yield of silage maize in northwest China. A field experiment was conducted in Liaojia Jiacou, Zhongchuan Town, Yongdeng County, central Gansu Province. The green storage maize variety 'Long Silage No.1' was used as material and four treatments were set up, which were common white mulch (M1), black ground cloth (M2), biodegradable film (M3), liquid mulch (M4). Plant height, stem diameter, leaf area, post-anther dry matter accumulation, ear yield, ear rate, grain moisture content, whole plant moisture content, fresh grass yield and hay yield were measured. The results showed that during mature stage, the height of M1 plants was 0.7%, 7.7% and 14.2% higher than that of M2, M3 and M4, respectively. M1, M2, M3 and M4 showed significant differences in stem diameter and plant height during jointing stage (P<0.05). During mature stage, the leaf area of a single plant showed M4>M2>M1>M3. Compared with M2, M3 and M4 treatments, the dry matter accumulation after flowering in M1 was 122.2%, 68.7% and 68.3% higher, the ear yield was 26.6%, 24.7% and 57.8% higher, the fresh grass yield was 6.5%, 9.0% and 10.2% higher, and the dry grass yield was 20.4%, 25.2%, and 36.9% higher, respectively. The ear rate and grain moisture content were shown as M4>M2>M3>M1 and the whole plant moisture content were shown as M4>M3>M2>M1. The study indicates that liquid mulch is not conducive to silage corn planting in northwest China. [ABSTRACT FROM AUTHOR]

Objective: To explore the influencing factors of sleep disorder and their effects on cognitive function, immune status and quality of life of the elderly in Chongwenmenwai Street community, Dongcheng District, Beijing. Methods: From January 2019 to December 2021, 386 elderly people in Chongwenmenwai Street community, Dongcheng District, Beijing were recruited as the research subjects. The incidence of sleep disorders was counted, and they were divided into normal sleep group and sleep disorder group according to the survey results. The baseline data of the two groups were compared, and the influencing factors of sleep disorders of the elderly in the community were analyzed by multivariate logistic regression. The immune status indexes of the elderly in the two groups were detected and compared. The simple mental state examination scale (MMSE) and SF-36 quality of life questionnaire were used to evaluate the cognitive function and quality of life of all subjects, and the differences between the two groups were compared. Results: Of the 386elderly in Chongwenmenwai Street community, Dongcheng District, Beijing, 165 had sleep disorders, the incidence of sleep disorders was 42.75%. The results of multivariate logistic regression analysis showed that women, without spouse or widowed, suffering from chronic diseases, bad living habits and bad mental state were the risk factors of sleep disorders in the elderly in Chongwenmenwai Street community, Dongcheng District, Beijing (OR=1.610, 1.293, 1.241, 1.412, 1.309; P all<0.05). The positive rates of CD3+, CD4+ cells and CD4+/CD8+ ratio in sleep disorder group were lower than those in normal sleep group, while the positive rate of CD8+cells was higher than that in normal sleep group (P<0.05). The MMSE score of sleep disorder group was significantly lower than that of normal sleep group (P<0.05). The scores of SF-36 quality of life in each dimension in sleep disorder group were lower than those in normal sleep group (P<0.05). Conclusion: The incidence of sleep disorders among the elderly in Chongwenmenwai Street community, Dongcheng District, Beijing is high, which is affected by gender, marital status, chronic diseases, living habits and psychological status, sleep disorders can also cause abnormal immune status and decline in cognitive function and quality of life, which should be paid high attention.

Serotonin is closely related to bone metabolism. Central serotonin promotes bone formation and inhibits bone resorption whereas peripheral serotonin promotes bone resorption. Peripheral serotonin acts on the 5-HT1 b receptors of osteoblasts, inhibits the binding of FOXO1 and CREB whereas promotes the binding of FOXO1 and ATF4, further inhibiting the cell cycle genes CYCD1, D2 and E1 in osteoblasts and the proliferation of osteoblasts. Lrp5 inhibits the Tph1 expression and the content of peripheral serotonin whereas promotes bone formation. Central serotonin acts on 5-HT2 c receptors in ventromedial hypothalamic nucleus neurons, activates CAM signal pathway and promotes CREB phosphorylation whereas inhibits sympathetic activity, RANKL expression and bone resorption. Leptin acts on the leptin receptors in serotonergic neurons, inhibits the synthesis of central serotonin and bone formation. In addition, 5-HT2 a receptors, 5-HT2 b receptors and 5-HT6 receptors are also involved in the regulation of bone tissue. Tph1 inhibitor LP533401 improves bone loss in ovariectomized mice. The role of central serotonin in promoting bone formation and the role of peripheral serotonin in promoting bone resorption are balanced in vivo, suggesting that there are some unknown feedback mechanisms connecting them, which provides us new research and clinical treatment ideas for osteoporosis.

Objectives: With the rapid development of China's high‐speed rail technology, the external geometric parameters rapid extraction of high‐speed railway is a new research topic. GNSS kinematic positioning has broad application prospects, but its accuracy is difficult to meet the requirements of track detection. Multipath effect is one of the main factors affecting the accuracy of GNSS kinematic positioning. At present, most of the existing multipath error reduction methods are suitable for static measurement, but there is no effective method to reduce the kinematic multipath error.Methods: The GNSS observation data are solved by using the traditional algorithm and the geometric information of track inspection as constraints, and then compared the measurement results affected by multipath with the accurate information of track inspection. Meanwhile, wavelet multi ‐ scale analytical method is applied to separating the multipath error from the noise in the coordinate residual sequence, and the clean coordinate series is obtained. Results: The accuracy of the double difference model can be improved by about 19% in the east‐west direction, 20% in the southnorth direction and 18% in the elevation direction based on the constrained adjustment with the track longitudinal level. Reducing and eliminating the multipath effect and noise in the coordinate domain by wavelet multi‐scale decomposition algorithm，the accuracy is improved about 19%‐21% in the east‐west direction, 15% ‐18% in the south‐north direction, and 9% ‐20% in the elevation direction. The combination of track longitudinal level constraint adjustment and wavelet filtering can improve the positioning accuracy by 35% in the east ‐ west direction, 31% in the south ‐ north direction and 25% in the elevation direction. Conclusions: The multipath error and observation noise can be effectively extracted by combining track inspection information with GNSS data, the multipath error in coordinate domain can be further weakened by wavelet correlation analysis, and the accuracy of GNSS kinematic positioning can be improved to meet the requirements of high‐speed track measurement.
