This paper takes A-share listed companies during 2010–2021 as the research object, and finds that the digital transformation (DT) of enterprises affects investors’ trading behaviours; more specifically, the digital transformation of enterprises increases investor divergence. This paper also finds that external governance factors mitigate the impact of digital transformation on investor divergence; specifically, analyst tracking mitigates the impact of digital transformation on investor divergence by alleviating information asymmetry. As more professional investors, institutional investors have stronger information mining and analysis capabilities, so the impact of digital transformation on investor divergence could also be mitigated with the increase in the proportion of institutional investors. The intermediary mechanism test suggests that corporate digital transformation triggers investor divergence by increasing surplus volatility. Further research finds that, firstly, different approaches to digital transformation have different impacts, with digital transformation through self-developed technology being more likely to trigger investor divergence. Secondly, different firm natures have different impacts, with the digital transformation of non-high-tech firms having relatively greater impacts on investor divergence. Finally, the digital transformation of non-state-owned enterprises has greater impact on investor analysis. [ABSTRACT FROM AUTHOR]

The link between civilization and technology has long been a hotspot of research around the world. Mobile phone addiction has become a common social phenomenon with advances in society and technology, wreaking havoc on people's emotional health, physical fitness, and personal connections. Considering the positive effects of mindfulness, this study used the diary method to explore the relationship between mindfulness and mobile phone addiction based on the mindfulness reperceiving model. We conducted a 14-day diary study among 198 Chinese youth participants. The results showed that there was a circular argument relationship between mindfulness and mobile phone addiction: mindfulness of the previous day could significantly negatively predict mobile phone addiction of the following day, and vice versa. These results, based on the mindfulness reperceiving model, effectively extend theories and profoundly reveal the circular argument relationship between mindfulness and mobile phone addiction. Besides, it also provides new thought for the mechanism of the interrelationship between mindfulness and mobile phone addiction, as an important theoretical support for the intervention of mobile phone addiction from the perspective of mindfulness.

The coupling capacitance between the line and the transducer cannot be ignored when making non‐contact voltage measurements on low‐voltage three‐phase power lines. This leads to an increase in the number of unknown capacitances, and the number of correlatable response voltage equations is less than the number of unknown coupling capacitances. In this paper, a simplified decoupling method is proposed based on the characteristics of triangular three‐phase lines erected in distribution areas. Firstly, the equivalent circuit measured by the voltage sensing mechanism during three‐phase operation is established, and the three‐phase line response voltage equation is derived. Secondly, this paper proposes a three‐phase line response voltage decoupling algorithm after designing the decoupling matrix. Then, this paper uses the least squares method to solve the coefficients in the equations. Finally, the three‐phase voltage fluctuations of the actual low‐voltage stations are simulated by simulation. The measured sensor voltage values are substituted into the algorithm to invert and calculate the three‐phase line voltage. The three‐phase phase error is less than 2°. The amplitude error is less than 1.77%. The experiment verifies the stability and accuracy of the proposed decoupling method. [ABSTRACT FROM AUTHOR]

Background: Periodontitis, one of the most common oral diseases, is a chronic inflammatory condition occur in response to bacterial plaque biofilms. Plaque control and oral hygiene instructions are the most widely used and effective nonsurgical treatment for periodontitis, which is based on a partnership between patient and clinician and requires a life-long commitment. The objective of this study was to analyze the effectiveness of internet-based nursing interventions for the treatment of patients with periodontitis. The findings from this study may help to enhance the therapeutic outcomes for patients with periodontitis. Methods: A total of 80 patients with periodontitis treated in Zhejiang Province Stomatology hospital from December 2021 to January 2023 were randomly selected and divided into control group and intervention group with 40 cases each. The control group was given routine oral health guidance and the intervention group received internet based nursing intervention. The periodontal pocket depth, percentage of periodontal pocket depth (PD) ≥ 4 mm, bleeding on probing (BOP)%, and self-efficacy scale for oral health care (SESS) were assessed and compared at four time points: initial visit, 6-8-weeks follow-up, 3-months follow-up, and 6-months follow-up. Results: There was no significant difference between the two groups in terms of age, gender, initial visit PD, initial visit PD ≥ 4 mm (%), initial visit BOP (%), and initial visit SESS (P > 0.05). The intervention group showed a significantly decreased percentage of PD ≥ 4 mm at 6–8 weeks and 6-months follow-up compared to the control group (P < 0.05). The PD, BOP%, and SESS scores of the intervention group were significantly better than those of the control group at 6-months follow-up (P < 0.05). There was no statistically significant difference in patient satisfaction between the two groups. Conclusions: This study confirmed that the internet-based nursing intervention in conjunction with periodontal treatment was able to improve the periodontal pocket depth, gingival bleeding and the level of self-efficacy of patients, suggesting that it is necessary to carry out the extended oral hygiene instructions via internet-based platforms for the patients in clinical practice.

Carbon family elements (Si, Ge, Sn, Pb) have attracted a lot of attention because of their unique structural features and potential applications in microelectronics industry. Here, the structure, chemical stability, electronic properties, and nonlinear optical properties of neutral and charged Au@X20H20 (X=Si, Ge, Sn, Pb) clusters have been systematically studied using density‐functional theory calculations. Structurally, the neutral/anionic Au@X20H20 (X=Si, Ge, Sn) as well as cationic Au@Pb20H20 possess Au‐endohedral (XH)20 unit, forming fullerene‐like framework, whereas other species are Au‐doped structures with hydrogen‐bridged bond. Analysis of binding energy and HOMO‐LUMO energy gaps reveals that the charged clusters possess high chemical stabilities due to closed‐shell structures. The charge transfers from X20 cage to Au atom, and the Au atom acts as electron acceptor. The Au atom and charged states play an important role in the structural stability, and can effectively modulate the electronic properties of clusters. Interestingly, the neutral Au@X20H20 (X=Si, Sn) clusters possess large first hyperpolarizabilities, especially for Au@Sn20H20, which has remarkably giant value (~5.65×108 a. u.), and the enhanced NLO behaviors can be further explained by the TDDFT calculation. The work may provide a theoretical reference for further applications considered as novel cluster‐assembled nanomaterials. [ABSTRACT FROM AUTHOR]

Background: The Citrus reticulata Blanco peels have been widely adopted as functional food or nutraceuticals for thousands of years. In our study, two polysaccharides from the C. reticulata Blanco peels were obtained and named as CRP-WA and CRP-02A, respectively. After characterization by monosaccharide composition, methylation and NMR, chemical structures of CRP-WA and CRP-02A were elucidated. Results: As a result, CRP-WA with Mw of 32.8 kDa was an arabinogalactan polysaccharide composed of (β1 → 3) (β1 → 3,6)-D-Galp, (β1 → 4)-D-Manp and (β1 → 4)-D-Glcp units in the backbone. The CRP-02A with Mw of 70.5 kDa was an arabinogalacturonan type pectin formed by (α1 → 4) (α1 → 3,4)-D-GalpA units in the backbone. Moreover, the surface morphologies and rheological properties of CRP-WA and CRP-02A were quite different from each other. Both of these two polysaccharides possessed good antioxidant activities and immunoregulatory effects on RAW 264.7 cells, in which CRP-02A behaved remarkable antioxidant feature, whereas CRP-WA showed relatively high immunoregulatory activity. Conclusion: Our study will provide fundamental information for C. reticulata Blanco-based nutritional foods development. [ABSTRACT FROM AUTHOR]

The control-structure interaction (CSI) between shaking table and eccentric load is one of the most important reasons causing the accuracy degradation of shaking table test. At present, the eccentric ratio (ER) of load and the coupling between actuators pose challenges to study the CSI. Thus, this paper establishes an analytical transfer function matrix of a shaking table and eccentric load. Based on the transfer function matrix, a comprehensive study is conducted to analyse the CSI effect under different eccentric ratio conditions. The analysis proves the influence of the CSI, and the CSI amplifies the actuator coupling more than 22 times at 20.00 Hz. Furthermore, a real-time CSI compensation strategy considering the actuator coupling is proposed. With the adopting of the proposed strategy, the coupling between two actuators is fully eliminated, and the correlation coefficients of ground motion records of two actuators are improved by 14.75% and 5.48%, respectively.

Altruism tendency is the cornerstone of a thriving society. Awe is a self-transcendent emotion with a great social function. The relationship between awe and altruism tendency has drawn considerable attention in the scientific literature. However, previous studies have mainly focused on the association from the perspective of dispositional awe. There is a lack of longitudinal research analyzing the immediate and lagged relationship between awe and altruism tendency using different methods at both trait and state levels, while also investigating their potential mechanism. The present study employed two complementary studies to examine the associations between awe, perceived social support, and altruism tendency at both trait and state levels. First, a longitudinal study was conducted over a 6-month period with 231 Chinese adolescents to explore the associations at the trait level (Study 1). The results revealed that dispositional awe had immediate and lagged effects on altruism tendency. Perceived overall social support, as well as support from different sources, played a mediating role in the delayed relationship between the two main variables. Subsequently, a sample of 117 Chinese adolescents completed the paper questionnaires once a week for seven consecutive weeks to investigate the within-subject relationships at the state level (Study 2). The results indicated that state awe had immediate and lagged effects on altruism tendency. Additionally, perceived support from family and significant others mediated the relationship between the two main variables at the within-subject level. These findings contribute to the social function theory of emotion by establishing a pathway of "emotion (awe) - cognition (perceived social support) - behavior (altruism tendency)" and provided empirical guidance for promoting prosocial behavior in adolescents.

Although previous cross‐sectional studies have investigated the between‐person correlation between dispositional envy and subjective well‐being, few longitudinal studies have explored the within‐person relationships between state benign/malicious envy and subjective well‐being, as well as the intrapersonal and interpersonal mechanisms involved. This study adopted a diary approach for 14 consecutive days from a sample of 167 young women to investigate the within‐person associations among benign/malicious envy, self‐esteem, perceived social support, and subjective well‐being. The results revealed that benign and malicious envy had opposite effects on subjective well‐being within individuals. Besides, the results indicated that self‐esteem and perceived social support mediated the relationships between benign envy and two dimensions of subjective well‐being (positive affect and life satisfaction) within individuals. Furthermore, self‐esteem played a within‐person mediating role in the relationships between malicious envy and three dimensions of subjective well‐being, whereas perceived social support only served as a within‐person mediator between malicious envy and positive affect. These findings shed light on the distinction between benign envy and malicious envy and help in comprehending the intrapersonal and interpersonal mechanisms through which the two types of envy impact subjective well‐being in daily life.

[Objective] In view of the lack of integrated facilities for measuring and controlling flow of Doudou (agricultural) channel in irrigation area, an integrated quantity control building-Measurement and Control Integrated Water Distribution Farm Gate was designed to explore its performance on trapezoidal channel. [Method] Using the combination of agricultural gate control disc valve and circular pipe to form an integrated water distribution gate (hereinafter referred to as the water distribution gate), the hydraulic characteristics and flow formulas of the water distribution gate under different flow rates and different opening of the agricultural gate control disc valve are studied by model test. [Result] ① The flow formula of Water Distribution Farm Gate was fitted and designed. The average error of the flow calculated by the formula was 4.34% compared with the measured flow, and the measurement error of flow was less than ±5%, which met the water accuracy requirements of irrigation area. ② The "optimal water head" of Water Distribution Farm Gate is between 0.475 and 0.575 L in the overall length of the pipeline. ③ The water distribution gate mainly produces local head loss and head loss along the distance when the water flow passes through the disc valve, and the range of head loss is 29.54% to 38.89%. [Conclusion] When the flow rate is in the range of 30 - 65 m³/h, under different flow conditions and disc valve opening degree, the water metering can be carried out in the final channel of the irrigation area. Therefore, Water Distribution Farm Gate has a high prospect of popularization and practical application value in the future. [ABSTRACT FROM AUTHOR]

To promote the application of non‐stacked particle damper (NSPD) in civil engineering, a design methodology was suggested on the basis of the double inert mass equivalent model. NSPD single‐story steel frame model is selected as the research object in this paper. First, the analytical solution for the periodic motion with symmetric two impacts was discussed. The shaking table test was performed to verify the rationality of the analytical solution under harmonic excitation. Subsequently, based on the analytical solution, the influence of equivalent connection stiffness on the vibration reduction effect and mechanism was analysed under resonant and non‐resonant harmonic excitation. The numerical analysis methods of the optimal equivalent connection stiffness were obtained accordingly. Finally, the effectiveness and generalization of the proposed optimal equivalent connection stiffness were discussed numerically under harmonic excitation and seismic ground motion. An optimal design process for the NSPD was proposed accordingly. Based on this, the vibration reduction performance analysis of NSPD under far‐field records, near‐fault pulse‐like records and near‐fault non‐pulse records was further conducted in the end. The results show that the time‐dependent frequency behaviour of the uncontrolled structure has a significant impact on the performance of the NSPD. The proposed optimization method is effective, which can be used as the foundation for the optimization of NSPD under earthquakes. [ABSTRACT FROM AUTHOR]

[Purpose/Significance] Generative artificial intelligence (AI) technology has been widely used in many fields, and the application of this technology has become popular among researchers. However, there are few studies on the willingness of researchers willingness to accept generative AI. This leads to an insufficient understanding of the psychological mechanism, cognitive process and behavioral pattern of users' acceptance of generative AI, which limits the ability of theoretical innovation and practical exploration in user information behavior. This study focuses on researchers acceptance of generative AI. By studying the evaluation process of ChatGPT by college students, it explores the acceptance behavior of generative AI. At the same time, it verifies the applicability of the AIDUA model in the new context, and introduces the new variable of school identity, which further extends the AIDUA model. [Method/Process] Based on the cognitive assessment theory and the AI acceptance framework (AIDUA), this paper constructs a theoretical model of the intention to use generative artificial intelligence, and develops and empirically tests the theoretical model of the intention to use generative AI. Taking college students as the main research object, based on the maturity scale in authoritative literature at home and abroad, 8 variables and 29 observation variables such as social influence, hedonic motivation and anthropomorphism were designed. College students with experience in using generative AI were invited to participate in the questionnaire survey. SPSS26.0 was used to analyze the data from 294 valid questionnaires collected. SmartPLS 3.2.9 was used to construct a structural equation model to test the hypothesis, and the JN method was used to detect the regulatory effect. [Results/Conclusions] The study found that users went through three stages of decision making before using generative AI. The PLS-SEM results show that: 1) Social influence, hedonic motivation and anthropomorphism significantly affect performance expectancy and effort expectancy, and anthropomorphism is the strongest variable affecting performance expectancy and effort expectancy. 2) Performance expectancy and effort expectancy are significantly negatively correlated with negative emotions, while hedonic motivation has no significant effect on negative emotions. 3) Negative emotions are significantly negatively correlated with users' intension to use. 4) School identity moderates the relationship between effort expectancy and negative emotions. This study combines anthropomorphic research on college students' acceptance of generative AI, and provides a framework for the acceptance of generative AI. Researchers can use this framework to better study the acceptance of AI. This study has some limitations. In the future, we will focus on the following three aspects: 1) to evaluate the users' acceptance of generative AI in different usage scenarios. 2) to use samples of other groups to test the applicability of the model, such as civil servants, librarians, researchers and other groups. 3) to incorporate variables from other technology acceptance models into the model, such as ease of use and practicality.

High‐throughput satellite (HTS) is an ideal way to realize cross‐regional massive, multifaceted digital exchange services, and it requires a signal processing module that can be massively multiplexed and has high flexibility. Due to the limitations of the frequency characteristics, microwave integrated circuits are difficult to meet this requirement. One solution to this problem is photonic integrated circuits (PICs). However, full‐size PIC satellite payloads containing main optoelectronic components are extremely challenging to implement on monolithic or hybrid integrated platforms. Here, the study demonstrates a hybrid integrated on‐chip microwave‐photonic satellite repeater with large‐scale multiplexing potential and high flexibility. This is a demonstration of a hybrid integration of a InP/Si3N4 external cavity laser, arrayed InP modulators, and semiconductor optical amplifiers (SOAs), as well as multifunctional Si3N4 signal processors, to fulfill a 1 × 4 Ka‐band repeater module with on‐chip arrayed frequency down‐conversion and outstanding narrowband photonic channelization. When combined with the full‐chip photonic RF repeater, broadband, highly integrated, and cost‐effective communications satellite payloads will become realizable more quickly in the near future.

Aggression has been receiving much attention always as it has serious negative effects. Moral disgust may be a protective factor against aggression. This study explores the mediating role of malicious envy and benign envy in the relationship between moral disgust and aggression from the perspective of integrative functional theory of moral disgust. The present study recruited 1052 participants and asked them to complete Three Domains of Disgust Scale (including Moral Disgust Subscale), Benign and Malicious Envy Scale, and Aggression Scale. The results showed that: (1) benign envy acted as a mediating variable between moral disgust and aggression, and played a partial mediating role. Malicious envy acted as a mediating variable between moral disgust and aggression, and played a full mediator role. In other words, both benign envy and malicious envy played an independent mediating role between moral disgust and aggression; (2) Benign envy and malicious envy are the mediator variables at the same time, only malicious envy can play a fully mediating role between moral disgust and aggression. That's to say, moral disgust can stably and significantly affect aggression through malicious envy. This study provided a theoretical reference to inhibit the generation of negative emotions and aggressive behaviors in social practice. [ABSTRACT FROM AUTHOR]

Summary: Grain size and weight determine rice yield. Although numerous genes and pathways involved in regulating grain size have been identified, our knowledge of post‐transcriptional control of grain size remains elusive. In this study, we characterize a rice mutant, decreased grain width and weight 1 (dgw1), which produces small grains. We show that DGW1 encodes a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family protein and preferentially expresses in developing panicles, positively regulating grain size by promoting cell expansion in spikelet hulls. Overexpression of DGW1 increases grain weight and grain numbers, leading to a significant rise in rice grain yield. We further demonstrate that DGW1 functions in grain size regulation by directly binding to the mRNA of Grain Width 6 (GW6), a critical grain size regulator in rice. Overexpression of GW6 restored the grain size phenotype of DGW1‐knockout plants. DGW1 interacts with two oligouridylate binding proteins (OsUBP1a and OsUBP1b), which also bind the GW6 mRNA. In addition, the second RRM domain of DGW1 is indispensable for its mediated protein‐RNA and protein–protein interactions. In summary, our findings identify a new regulatory module of DGW1‐GW6 that regulates rice grain size and weight, providing important insights into the function of hnRNP‐like proteins in the regulation of grain size.

Objective: Acute kidney injury (AKI) is a clinical syndrome that occurs as a result of a dramatic decline in kidney function caused by a variety of etiological factors. Its main biomarkers, serum creatinine and urine output, are not effective in diagnosing early AKI. For this reason, this study provides insight into this syndrome by exploring the comorbidities of AKI, which may facilitate the early diagnosis of AKI. In addition, organ crosstalk in AKI was systematically explored based on comorbidities to obtain clinically reliable results. Methods: We collected data from the Medical Information Mart for Intensive Care-IV database on patients aged ≥ 18 years in intensive care units (ICU) who were diagnosed with AKI using the criteria proposed by Kidney Disease: Improving Global Outcomes. The Apriori algorithm was used to mine association rules on the diagnoses of 55,486 AKI and non-AKI patients in the ICU. The comorbidities of AKI mined were validated through the Electronic Intensive Care Unit database, the Colombian Open Health Database, and medical literature, after which comorbidity results were visualized using a disease network. Finally, organ diseases were identified and classified from comorbidities to investigate renal crosstalk with other distant organs in AKI. Results: We found 579 AKI comorbidities, and the main ones were disorders of lipoprotein metabolism, essential hypertension, and disorders of fluid, electrolyte, and acid-base balance. Of the 579 comorbidities, 554 were verifiable and 25 were new and not previously reported. In addition, crosstalk between the kidneys and distant non-renal organs including the liver, heart, brain, lungs, and gut was observed in AKI with the strongest heart-kidney crosstalk, followed by lung-kidney crosstalk. Conclusion: The comorbidities mined in this study using association rules are scientific and may be used for the early diagnosis of AKI and the construction of AKI predictive models. Furthermore, the organ crosstalk results obtained through comorbidities may provide supporting information for the management of short- and long-term treatment practices for organ dysfunction.
