In recent years, the discussion about media technology and identity in scholarship of communication is mainly unfolded along two theoretical lines. One is to explore the value of "online community" through new media technologies. focusing on whether and how online interpersonal communication through social media can enhance identity recognition. The other is the role of "media sense of place" in locative media practice. However, the research of "online community" inherits Tonnies' concept of "community", and its applicability in the digital society is still questionable. In addition, the above two research directions respectively focus on online interpersonal communication and offline media practice, but overlook the new experience of the "online-offline" hybrid digital city shaped by smartphones. This study adopts a qualitative research method, looking for research subjects in a snowball search way and conducting in-depth interviews with 27 young floating talents during November 15th-25th in 2019 and April 5th-30th in 2022. To ensure material heterogeneity, the young floating talents from Wuhan and Xi'an were selected as key research subjects, while others residing in Beijing, Shanghai. Shenzhen. Guangzhou, and Chongqing were selected as the control group. We focused on their everyday life experiences in networked cities to explore the uniqueness of mediation with smartphone and the new variety of community. The results show that digital technology reshapes the notion of attachment itself. Attachment is rescripted from "belonging" to "co-existence". To be specific. smartphones commingle "de-spatialized" interpersonal interactions with "co-existing" urban experiences, making intimacy and human-land relationships intertwined but separated from each other. Owing to this mediation practices. the young floating talents who use smartphones everyday fostered a multi-sense of attachment which is looseness, differentiation and instability. Compared with the existing literature, this paper contributes in two aspects: firstly, the authors attempt to clarify the changes of attachment in digital contexts, avoiding the stereotype of measuring the new social reality based on the community perception formed by rural society and traditional communication technologies. Secondly, this study unifies the notion of "online community" and "media sense of place" into the concept of attachment. The focusing point was not on the use of media, but on the digital life practice of young floating talents transitioning online and offline. The residing willingness of young floating talents is very important for large and medium cities in China. This study explores possible paths to enhance urban attachment in the digital age from the perspective of media technology, providing reference value for cities to retain young floating talents as soon as possible.

Objective To observe the effect of arbutin(AR)on myocardial injury in diabetic cardiomyopathy(DCM)mice, and to explore whether the protective action of AR is related to silencing information regulator 1（SIRT1）. Methods Sixty male C57BL/6 mice were randomly divided into the Con group, DCM group, DCM+AR group and DCM+ AR+EX527 group, with 15 mice in each group. Except the Con group, the DCM mouse models were established by intra‐ peritoneal injection of streptozotocin combined with high-glucose-high-fat diet in the other groups. AR of 50 mg/（kg·d)was given in the DCM+AR group and DCM+AR+EX527 group through intragastric administration for 12 weeks. At the same time, EX527（20 mg/kg)was given in the DCM+AR+EX527 group through intraperitoneal injection, once a week, with a total of 11 injections. The left ventricular ejection fraction(LVEF)and left ventricular fraction shortening(LVFS）were calculated, the degree of myocardial fibrosis and collagen deposition were observed, and the expression levels of su‐ peroxide dismutase(SOD）, malondialdehyde(MDA)and reactive oxygen species(ROS)were compared. The expression of NF-κB in the myocardial tissue was observed by immunofluorescence staining, and the deacetylation activity of SIRT1 was detected by ELISA kit. Real-time quantitative PCR was used to detect the mRNA expression levels of Collagen1, Col‐ lagen3, nicotinamide adenine dinucleotide phosphate oxidase 2（NOX2）, nicotinamide adenine dinucleotide phosphate ox‐ idase 4（NOX4）, interleukin-6（IL-6）, and tumor necrosis factor-α（TNF-α）. Western blotting was used to detect protein expression levels of SIRT1 and pyroptosis-associated molecules including Nod-like receptor thermal protein domain associ‐ ated protein 3（NLRP3）, apoptosis-associated speck-like protein(ASC）, interleukin-1β（IL-1β）, interleukin-18（IL18）, and cleaved Caspase-1. Results There were no significant fibrosis and collagen deposition in the Con group, that was, there were no obvious blue collagen fibers and red collagen staining in the myocardial tissues. Compared with the Con group, the degree of myocardial fibrosis and collagen deposition in the DCM+AR group, DCM group and DCM+AR+ EX527 group increased, with more significant changes in the DCM group and DCM+AR+EX527 group. Compared with the Con group, LVEF, LVFS, SOD expression and SIRT1 deacetylation activity decreased, but the relative expression levels of NF-κB, MDA, ROS, and the mRNA levels of IL-6, TNF-α, Collagen1, Collagen3, NOX2, and NOX4 increased in the DCM+AR group, DCM group and DCM+AR+EX527 group, with more significant changes in the DCM group and DCM+AR+EX527 group(all P<0. 05）. Compared with the Con group and DCM+AR group, the protein expression levels of SIRT1 significantly decreased, while the protein expression levels of NLRP3, ASC, IL-1β, IL-18, and cleaved Cas‐ pase-1 significantly increased in DCM group and DCM+AR+EX527 group(all P<0. 05）. Conclusions AR can mitigate the oxidative stress and inflammatory response in the myocardial tissues, and then inhibit the inflammasome formation and cardiomyocyte pyroptosis, thus finally alleviating the myocardial injury of DCM mice. The mechanism may be related to the activation of SIRT1 signaling pathway. [ABSTRACT FROM AUTHOR]

A large amount of agricultural waste has been generated each year in China, particularly with about 900 million tons of crop straw and 260 million tons of tailings. The proper disposal can greatly contribute to the high utilization of agricultural waste in the environmental ecosystems, and the less surface pollution in farmland. However, the current resource utilization of agricultural waste has posed a great challenge, such as straw and livestock manure. It is a high demand to find a rational way for the sustainable production of agricultural waste. In this study, a drought-resistant and root-promoting substrate culture was fabricated to mix the compost and crop straw with clay, in order to improve the utilization rate of agricultural waste. A systematic investigation was made to clarify the effect of water-fertilizer coupling on the growth, yield, quality, water use efficiency (WUE), and partial factor productivity of fertilizer (PFP). Taking the tomatoes were grown on "Aegis 3041" as a test crop, nine water-fertilizer coupling treatments were set using substrate cultures, i.e., three groups of drip irrigation water W1, W2, and W3 (high water: 100% ET0, medium water: 80% ET0, low water: 60% ET0, where ET0 was the reference crop evapotranspiration), while three groups of fertilizer F1, F2 and F3 (N-P2O5-K2O) levels (high fertilizer: 240-115-137 kg/hm², medium fertilizer: 180-88-121.2 kg/hm², low fertilizer: 112-50-82 kg/hm² ), and the CK was used as a control group with reference to the actual local production of water and fertilizer. A total of 10 coupled treatments were developed to comprehensively evaluate the tomato yield, WUE, PFP, and overall fruit quality. A genetic algorithm (GE) multi-objective optimization model was also established to optimize the evaluation. The results showed that the plant height of tomatoes in the substrate culture presented a trend of increasing and then decreasing, with the increase of irrigation amount during each fertility period. The mass, surface area, and length of root increased by 36.9%, 4.0%, and 6.3%, respectively, under the same fertilizer application conditions, compared with CK. Correspondingly, the substrate culture was effectively improved the plant height, stem thickness, root development, yield, quality, WUE, and PFP. The VIKOR method was used to comprehensively evaluate the fruit quality of each treatment. The fruit flavor quality and yield of tomatoes cultivated in substrate were significantly improved. The tomato flavor quality and yield were the best under the W3F1 treatment, and the benefit ratio was the smallest. The GE multi-objective optimization demonstrated that the best irrigation-fertilization treatment was W3F2 for the substrate culture, with the highest yield of 25.85 t/hm², a lowest WUE of 13.77%, an optimum sugar to acid ratio of 9.51, and a benefit ratio of 0.357. Consequently, the substrate culture cultivation technology can be widely expected to save the water and fertilizer for the higher productivity and quality of fruits and vegetables, there by efficiently improving the utilization rate of agricultural waste resources. The effective way can be served to dispose of the agricultural non-point source pollution for the fewer carbon emissions in the sustainable crop production. The photovoltaic plus brick development can greatly contribute to transforming facility agriculture into natural agriculture in the future, such as the rich land resources in northwest China. This finding can also provide theoretical support to the efficient use of agricultural waste, as well as the rational management of water and fertilizer for the high-quality fruits and vegetables in modern agriculture.
