The variation rule of deformation structure and magnetic properties of high strength non-oriented electrical steel with cold rolling were studied by field emission scanning electron microscopy(SEM+EBSD), rapid temperature tube furnace and AC magnetic properties measuring instrument. The results show that the rough strips with a large number of substructures and smooth strips with a small amount of deformation are formed in cold-rolled high strength non-oriented electrical steel. The rough strip has a γ orientation, mainly {111}〈110〉, and the smooth strip has a {112}〈110〉 and {001}〈110〉 orientation. In the rough strips, there are a lot of shear bands with width of about 2-3 μm, which show an angle of 20°-35°to the rolling direction. And the quantity increases gradually with the increase of the reduction rate. There is a certain misorientation between the shear band and the matrix. With the increase of the reduction rate, the shear band gradually changes from {111}〈110〉 to {223}〈110〉, and the misorientation between the shear band and the matrix gradually increases. After annealing, the texture of Goss and {111} increases, while the texture of {001} decreases. The rolling direction magnetic induction intensity increases, the transverse magnetic induction intensity decreases, the magnetic anisotropy is significant, and the iron loss decreases.

Seven samples of Wuyi rock tea (cv. Shuixian) stored for different times (0, 5, 10, 15, 20, 25, and 30 years) were collected to investigate the effect of storage time on the flavor quality of Wuyi rock tea by the combined use of sensory evaluation, non-volatile and volatile composition analysis and chemometrics methods. The results showed that the transformation of the flavor quality of Wuyi rock tea during storage was divided into three stages: 0–5, 10–15, and 20–30 years. As the storage time increased, the taste gradually transformed from mellow to stale, and a sour taste appeared at the middle stage of storage and then faded away at the late stage. The aroma gradually changed from flowery and fruity to aged, woody and herbal. A significant decrease in the content of tea polyphenols, catechins-like and theaflavins and an increase in the content of soluble sugars were the major reasons for the taste changes. Changes in the contents of 15 characteristic volatiles, including indole, trans-nerolidol, dihydroactinidiolide, hotrienol, α-terpineol, methyl salicylate, β-ionone, and (Z)-hexanoic acid-3-hexenyl ester, were the key factors affecting the aroma changes. This study provides a scientific reference for the storage and consumption of Wuyi rock tea.

In the context of big data’s growing influence on education, our study presents a novel approach to managing higher vocational student data through a model based on the “three-round education” philosophy. We construct a predictive model to dissect and categorize student performance at X higher vocational college by integrating K-prototypes and LSSVM algorithms. Our findings reveal three primary groups: high achievers (43.65%), average performers (23.38%), and those with challenges (32.97%), each showing apparent differences in academic success indicators. Impressively, the model forecasts student enrollment numbers with less than 1.077% error, providing a reliable tool for educational administrators to make informed decisions and tailor student management strategies effectively.

Correct network topology is the basis of power grid analysis and control. Because of the lack of measurement on breakers， the identification of breaker states is particularly important in the distribution network. According to the characteristics of closed-loop construction and open-loop operation of the distribution network， section breaker graph is developed to describe the connectivity of the distribution network. The property of tree is used to describe the radial structure constraints of the operation of the distribution network. Based on the principle of weighted minimum absolute value， a identification model is developed， which aims to minimize the adjustments of breaker states and the sum of weighted absolute value of measurement errors. The proposed identification model is a mixed integer linear programming （MILP） problem in mathematic， which can be solved by the simplex method combined with the branch and cut frame. The correctness of proposed model and effectiveness of the proposed method are verified by simulation case.

The digital and programmable metasurfaces, as opposed to conventional metasurfaces, offer a more sophisticated method of collaborating information and physics, showcasing several real-time controls to electromagnetic (EM) ways in succinct ways. In this work, we propose a multi-frequency amplitude-programmable (MFAP) metasurface with multiple frequency channels to enhance the presentation and manipulation of EM data. With this metasurface, the reflected amplitudes can be simultaneously and independently encoded between high (digit “1”) and low (digit “0”) levels. The amplitude code is unique, which exhibits both reflection coefficients and radiation patterns to allow for flexible multi-functional EM operations with frequency. For instance, the MFAP metasurface can be used to design innovative communication systems by transmitting various EM signals individually across the channels in time domain. It is also possible to carry out multi-bit transmissions by mixing these frequency channels. By introducing complex coding patterns in space domain, it is possible to manipulate EM powers with greater precision. A square-split ring meta-atom that can achieve stable single-frequency amplitude control and multi-frequency 1 bit amplitude-programmable features is described as a proof-of-concept. Varactors loaded on metallic structures of various sizes are switched between operating states to modify the amplitude codes at each frequency channel. The suggested MFAP metasurface’s validity is confirmed by simulations and measurements from a dual-channel MFAP metasurface prototype.

BACKGROUND The fast detection of Cu, Pb, Zn and Ni in geochemical samples helps to determine the level of heavy metal pollution, thus assisting in the employment of efficient treatments. OBJECTIVES To establish a method for the simultaneous determination of Cu, Pb, Zn and Ni in geochemical samples by AC Arc direct reading atomic emission spectrometry with solid sampling technique. METHODS With sodium fluoride, alumina, silicon dioxide and carbon powder as buffer agents and germanium as the internal standard element, the element analysis line pairs were optimized, and the exposure time was also optimized at 25s. The standard curve of synthetic silicate was corrected using national first-class reference materials (soil, rock and sediment), so as to reduce the interference of the matrix. Sensitive line and hyposensitive line were selected to enhance the accuracy as well as expand the measurable linear range of elements. Average value of two parallel analyses was adopted for further improved analytical precision. RESULTS The detection limits of Cu, Pb, Zn and Ni were 0.45μg/g, 1.46μg/g, 2.40μg/g and 1.58μg/g, respectively. The precision ranges of the method were 1.36%-6.25% for Cu, 1.17%-8.06% for Pb, 1.64%-9.68% for Zn and 0.91%-5.31% for Ni. Measured values with this method for the national first-class reference materials of soil, sediment and rock were consistent with the certified values (|△logC| ≤ 0.05), qualification rates of the actual samples and external quality control samples were all above 90%. CONCLUSIONS With simple operation, direct solid sampling technique is applied. The method reported here is more environmentally friendly compared to the acid dissolving method, sample contamination caused by reagent blank and vessels used is avoided at the same time. The average results of twice spectral acquisitions are calculated, which is more accurate and precise than the single analysis reported in the literature. All indicators of this method are better than the requirements of regulation (1:250000) DZ/T 0130.5-2006.

Due to the limitations of configuration scenarios， energy storage capacity configuration takes long time and the net profit value of energy storage capacity is small. Research on energy storage capacity configuration method for power system based on an improved particle swarm optimization （PSO） is proposed. First， the power system energy storage capacity is determined， and the storage capacity configuration constraints are analyzed in respect of the remaining power， charging and discharging efficiency， and reliability of the energy storage system； then， with the objective of maximum net revenue of storage capacity configuration， an economy model of the power system is constructed， and the improved particle swarm algorithm is introduced to solve the model and complete the configuration of the power system energy storage capacity. The experimental results show that the proposed method takes shorter configuration time while owning higher net energy storage capacity revenue， which verifies the application performance of the method.

Objective To explore the intertemporal decision⁃making disorder in patients with Parkinson's disease (PD). Methods From January 2020 to August 2021, a total of 36 patients with PD (PD group) who diagnosed and treated in The Second People's Hospital of Hefei and The Second Affiliated Hospital of Soochow University were selected, and 39 healthy controls (control group) with matched gender age and eudcation were recruited. Hamilton Anxiety Rating Scale (HAMA), Hamilton Depression Rating Scale (HAMD), Mini⁃Mental State Examination (MMSE), Verbal Fluency Test (VFT), Digit Span Test (DST), and Stroop Color⁃Word Test (SCWT) were used to evaluate the neuropsychological characteristics, the delay⁃discount rate K value in the intertemporal decision⁃making paradigm were used to evaluate the intertemporal decision⁃making ability. Results Compared with control group, the PD group had a decrease in MMSE score (Z=⁃4.536, P=0.000), correct number of VFT (Z=⁃4.555, P=0.000), correct repetition of DST⁃forwards (Z=⁃4.696, P=0.000) and DST⁃backwards (Z=⁃3.261, P=0.001), while had an increase in HAMA score (Z=⁃5.153, P=0.000), HAMD score (Z=⁃5.637, P=0.000), Stroop C-A (Z=⁃7.105, P=0.000) and K value (Z=⁃3.209, P=0.004). Correlation analysis showed that there was no correlation between K value and MMSE score, correct number of VFT, Stroop C-A, and correct repetition of DST⁃forwards and DST⁃backwards in PD patients (P＞0.05, for all). Conclusions Patients with PD have symptoms of intertemporal decision⁃making disorder. They can't reasonably balance the value of delayed reward, prefer immediate reward, and have more impulsive decision⁃making behavior.

Building long-lasting antimicrobial and clean surfaces is one of the most effective strategies to inhibit bacterial infection, but obtaining an ideal smart surface with highly efficient, controllable, and regenerative properties still encounters many challenges. Herein, we fabricate an ultrathin brush–hydrogel hybrid coating (PSBMA-P(HEAA-co-METAC)) by integrating antifouling polyzwitterionic (PSBMA) brushes and antimicrobial polycationic (P(HEAA-co-METAC)) hydrogels. The smart bacterial killing–releasing properties can be achieved independently by the opposite volume and conformation changes between the swelling (shrinking) of P(HEAA-co-METAC) hydrogel layer and the shrinking (swelling) of PSBMA brushes. The friction test reveals that both METAC and SBMA components support great lubrication. By tuning the initial organosilane (BrTMOS:KH570) ratios, the prepared PSBMA-P(HEAA-co-METAC) coating exhibits different antibacterial abilities from single “capturing–killing” to versatile “capturing–killing–releasing.” Most importantly, 99% of the bacterial-releasing rate can be easily achieved via 0.5 M NaCl treatment. This smart surface not only possesses long-lasting antibacterial performance, only ∼1.09 × 105 cell·cm−2 bacterial residue even after 72 h exposure to bacteria solutions, but also can be regenerated and triggered between water and salt solution multiple times. This work provides a new way to fabricate antibacterial smart hydrogel coatings with bacterial “killing–releasing” functions and shows great potential for biomedical applications.

Approximately a third of Malaysian adult has been diagnosed with hypertension. This study aimed to investigate the prevalence and key risk factors of hypertension in a community living in a rural area of Kudat, Sabah. Methods: The study included participants of at least 18 years old, able to communicate in the local dialect, no mental disability, not pregnant or lactating and no known cause of secondary hypertension. Sociodemographic data were recorded in addition to assessment of depression, anxiety, stress, and dietary salt of the participants using standard DASS-21 questionnaire (Depression Anxiety Stress Scales standard questionnaire) questionnaire. Multiple logistic regression analyses were used to assess the association of hypertension and health-related variables predicted to be a risk factor. Results: Out of 111 participants, 30% were diagnosed with hypertension of which 60.6% were not aware of their health condition. Among the variables analyzed, higher age (at least 40 years old) and excess BMI (≥23.0) highly contributed to the predisposition of hypertension (p0.05). Conclusion: The community in Kudat, as a representation of the rural population in Sabah, has a high prevalence of hypertension, implying that lifestyle changes and regular health checks are effective interventions to minimise the risk of hypertension.

The Fuchuan peridotites have dual features of mid-ocean ridge basalt and supra-subducted zone peridotites and have been experienced high degrees of partial melting; chondrite-normalized “U”-shaped rare earth element (REE) patterns of Fuchuan harzburgites indicate that light REE enriched SSZ melts or fluids have participated in the interaction with peridotites; the Fuchuan chromitites are enriched in IPGE and depleted in PPGE, which are basically consistent with high-Al chromitites worldwide, and the low PGE concentrations of chromitites reflect a lack of sulfur saturation of the parental melts during an early stage of their crystallization; the Fuchuan peridotites and chromitites are believed to be formed in a back-arc spreading ridge between the Yangtze and Cathaysia blocks during 860–820 Ma.

Osteosarcoma (OS) is the most common type of primary malignant bone tumor. The early lung metastasis of osteosarcoma is one of the main factors of poor prognosis. Therefore, searching for new targets and new mechanisms of osteosarcoma metastasis is essential for the prevention and treatment of osteosarcoma. Our previous studies suggested that fatty acid synthase (FASN) was an oncogene and promoted osteosarcoma. In addition, it is reported that the expression of miR-195 was negatively correlated with osteosarcoma. Aberrant DNA methylation can reversely regulate the expression of miRNAs. However, whether miR-195 could target FASN in osteosarcoma and whether ectopic DNA methylation is the upstream regulatory mechanism of miR-195 in metastasis of osteosarcoma are not fully studied. The expressions were detected by qPCR and western blot, and methylation level was determined by methylation-specific PCR. Luciferase reporter assay, MTT, wound healing, and Transwell assay were used. We found that the expression of miR-195 was low in osteosarcoma. The methylation of miR-195 was high. miR-195 targeted and decreased the expression of FASN. In osteosarcoma, miR-195 inhibited cell proliferation, cell migration, and invasion. The methylation of miR-195 was related to decreased miR-195, it might promote osteosarcoma.

Introduction: The structure of green and low-carbon ports is complex, and an integrated port energy system with complex characteristics such as multi-energy flow coupling and information physical fusion has been formed.Methods: Digital twin technology provides a new solution for the perception, analysis, and optimization of integrated port energy system. The paper explores the digital twin of integrated port energy system. Based on the development trend and function of integrated port energy system, the digital twin of integrated port energy system architecture is proposed to explore its potential application services. Specifically, considering the functions and structural characteristics of the port, the digital space of integrated port energy system is established, which describes the pan electrification, multi energy flow fusion, the “physics-information-value” coupling, and the characteristics of system operation under uncertain scenarios of integrated port energy system from the physical and data dimensions. The hybrid driving method based on data and mechanism is used to explore digital twin of integrated port energy system and find potential better applications.Results and discussion: Finally, combined with the current development needs of integrated port energy system, this paper analyzes the key problems and technologies that need to be broken through in the specific implementation of digital twin of integrated port energy system, with a view to providing some thoughts and references for the low-carbon development of ports and the future application of digital twin technology under the goal of “double carbon”.

Aiming at the problem of insufficient adaptability to the new elements of the new power system in the current distribution network investment method, this paper innovatively proposes a distribution network investment method based on the new power system. By constructing a source-grid-load-storage-side investment calculation model, the investment in the new power system can be accurately calculated. First, the distributed power investment is calculated from the two aspects of new construction and renovation. Secondly, construct the grid investment demand and grid investment capacity measurement model, and obtain the grid side investment model by weighted summation. Then, a model for calculating the scale of investment that can be saved due to demand-side response is constructed, and the cost of demand response is subtracted to obtain a model for calculating the scale of investment that can be saved on the load side. Finally, the energy storage side investment calculation model is constructed from the power supply side, grid side, user-side energy storage investment, and energy storage investment benefit. The research results are applied to the empirical area, and scientific guidance is provided to realize the precise investment in the area.

An increasing number of studies have reported that microbiome can affect drug response by altering pharmacokinetics and pharmacodynamics of formation of toxic metabolites. With the development of metagenomic sequencing, gut microbial composition as well as the metabolic function are drawing more and more attention for the patient stratification. The established microbiota databases provide useful information about the gut microbe-drug interactions. However, these databases generally lacked the detailed effects on substance and the metabolites, which are helpful in elucidating the mechanisms underlying drug biotransformation and personalized medicine. To address these issues, in this study, we developed Metabolic action of gut Microbiota to Drugs (MagMD), a database and a web-service covering 32, 678 records of interactions between 2,146 gut microbes, 36 enzymes and 219 substrates (mainly drugs). The detailed annotations for each entry, including the taxonomic level of microbes, the molecular form and PubChem ID of drugs from PubChem Compound Database, types of microbial secreted enzymes and the original reference links can also be accessed from the web service. Availability and implementation: MagMD is a publicly available resource, constantly updated. It has an intuitive web interface and can be freely accessed at http://www.unimd.org/magmd.

F-doped ZnO (FZO) films were prepared by reactive sputtering using Zn/ZnO/ZnF2 mixture as the target at substrate temperature (Ts) of 150℃ and 300℃ and sputtering atmosphere of Ar+O2 and Ar+H2. The effect of gas flux, Ts, and sputtering atmosphere on the structure and transparent conductive properties of the thin film was investigated. The results show that for FZO films prepared under Ar+O2, Ts=300℃ is conductive to the preparation of films with (002) preferred orientation, high crystallinity, low compressive stress and good transparent conductive properties. For the films prepared under Ar+H2, with the increase of Ts to 300℃, the crystallinity and transmittance of the films improve and the compressive stress reduces, but the film thickness significantly reduces and leads to the deterioration of the conductive properties of the films. The FZO films prepared in the two atmospheres are compared, and it is found that the films prepared in Ar+H2 can obtain better transparent conductive properties (the resistivity of 3.5×10-3 Ω·cm and the average transmittance in visible range of 87%) at 150℃ and in H2 flux range of 0.8-3.2 mL·min-1. The etching effect of H plasma and H doping in the Ar+H2 atmosphere, the bombardment of O ions and the change of oxygen defects of the films in the Ar+O2 atmosphere, the enhancement in reaction activity and mobility of deposited atoms with increasing Ts, and the relationship between Eg and carrier concentration are discussed in detail.

Diabetic peripheral neuropathy (DPN) is one of the most common chronic complications of diabetes. Traditional DPN diagnostic methods are based on clinical symptoms and signs as well as electrophysiological examination, which are mainly used to detect the lesions of large nerve fibers. However, the small nerve fibers are the earliest ones damaged in DPN. Corneal confocal microscopy (CCM) can analyze the changes of corneal nerve fibers under a high power microscope. It is a rapid, repeatable and quantitative noninvasive technique to measure small nerve fibers. It can diagnose DPN early and evaluate neuromorphological changes prospectively. It has a good application expectation. During this article, we summarized the role and limitations of DPN's most reliable parameters of corneal nerve in evaluating diabetic autonomic neuropathy and diabetic micro-vascular complications. Further, we reviewed the clinical application of CCM in evaluating diabetic neuropathy and analysis methods of CCM related artificial intelligence, in order to provide references for clinical diagnosis and treatment.

The construction industry is a pillar of the national economy. The complex international competition and the pressure from domestic reforms necessitate improvement on the core competitiveness of Chinese construction enterprises. In this article, we first analyze the development status and challenges of the core competitiveness of Chinese construction enterprises. Subsequently, we summarize the factors that influence the core competitiveness of Chinese construction enterprises using a fishbone diagram and through literature review and expert consultation, including human resource management, scientific and technological innovation, culture and brand building, project management, professional construction, and industrial chain integration. Furthermore, we propose corresponding suggestions and countermeasures from the perspectives of government and enterprise. Specifically, the government should improve the mechanism of scientific and technological innovation, improve relevant standards and policies of green construction, and enhance industry governance. Moreover, construction enterprises should improve the quality of human resource management, promote scientific and technological innovation, create brand soft power, integrate high-quality resources of the industrial chain, and promote core business advantages.

The purpose of the current study was to characterize role of microRNA (miR)-519d in trophoblast cells and preeclampsia (PE) development and its potential underlying mechanism. Regulation of leptin (LEP) by miR-519d was verified using a dual-luciferase reporter gene assay. Loss- and gain-of-function assays were conducted to detect the roles of miR-519d and LEP in proliferation, migratory ability, and invasive capacity of HTR-8/SVneo cells by means of CCK-8 assay, scratch test, and Transwell invasion assay, respectively. The cell apoptosis rate and cycle distribution were analyzed by flow cytometry. LEP expression was elevated, whereas miR-519d level was suppressed in the PE placenta samples compared with those from normal pregnancy. Depletion of LEP promoted proliferation, migratory ability, and invasive capacity and repressed apoptosis. miR-519d could bind 3′ untranslated regions (3′UTRs) of LEP, the extent of which correlated negatively with LEP expression. miR-519d suppressed the expression of LEP in HTR-8/SVneo cells. Moreover, overexpression of miR-519d promoted survival and migratory ability of HTR-8/SVneo cells. Taken together, we find that miR-519d targeted LEP and downregulated its expression, which could likely inhibit the development of PE.

Under global economic competition, rescaling has become an important cross-border governance means to control the development of domestic space to attract capital flows and foster regional economic development momentum. City integration is a kind of urban regional scale, and its mechanism of cross-border governance has gradually become an important regional integration issue. At present, research on cross-border governance from the perspective of rescaling focuses on urban areas represented by urban agglomerations and metropolitan areas and new functional areas represented by state-level new areas, with limited research on the scale of city integration at the meso level. The discussion on the role and status of corresponding governance subjects, construction mechanisms, and incentive mechanisms needs to be enriched. In this paper, the evolution of cross-border governance is discussed from the perspective of rescaling, taking Guangfo city integration, which is relatively mature in the process of domestic city integration, as an example. The study finds that, taking the introduction of the outline of the reform and development plan for the Pearl River Delta region in 2008 and the outline of the development plan for the Guangdong-Hong Kong-Macao Greater Bay Area in 2019 as the target, the city integration process of Guangfo has experienced two stages of rescaling: from the governance scale of an "administrative area" to that of a "functional area" represented by the pilot zone for the high-quality development integration of Guangfo. By comparing and analyzing the cross-border governance mechanisms of city integration across different scales, this study finds that the city integration governance stage of the "functional area" scale, first, enriches the participation of multiple governance subjects, extending from "city-district-town" multi-level government to the functional platform management committee and platform joint venture company. Second, on the basis of the project implementation mechanism led by municipal departments, the construction mechanism strengthens the planning, construction, and operation mechanisms guided by functional areas and, taking the whole cycle as the concept, increases emphasis on integrated planning, construction, and operation. Third, the incentive mechanism has shifted from the driving of political instructions and economic benefits to the striving for policy and the sharing of institutional dividend. Both "administrative area" and "functional area" are the positive scales restructuring strategy of Guangfo to deal with the global competitive environment and respond to the requirements of national strategy. The two-stage cross-border governance mechanism is neither beneficial nor harmful, but is a choice to adapt to the different development stages of city integration. The governance mechanism of the "functional area" scale can be regarded as the experience retention and gradual reform of Guangfo's original governance mechanism, to improve the governance efficiency of the city integration and competitiveness. Guangfo's practice of using rescaling to promote cross-border governance reform and deepening in the last ten years can provide a certain reference for cross-border governance in the Guangdong-Hong Kong-Macao Greater Bay Area and other metropolitan areas in China. However, it should be pointed out that at present, the rescaling of the pilot area is more reflected in spatial planning and cooperation agreements, and has failed to produce a spatial governance subject that is fully integrated with the new scale. In addition, the deeper benefit sharing and risk responsibility sharing mechanism still needs to be strengthened.

The hot corrosion behavior of the second generation nickel base single crystal superalloy DD421 coated with 90%(mass fraction) Na2SO4+10%NaCl (molten at 750 ℃) and pure Na2SO4 (solid state at 750 ℃) was investigated by salt coating method in 750 ℃ atmosphere (without SOx atmosphere). The results show that in the corrosion medium of molten mixed salt, the sulfidation reaction is mainly caused by the corrosion of liquid molten salt. After 100 h of hot corrosion, the main corrosion products are typical simple oxides (Al2O3, Cr2O3, TiO2) and Ni/Cr/Ti sulfides. However, in the pure Na2SO4 solid salt hot corrosion experiment, the corrosion products of the alloy after 100 h of hot corrosion are basically the same as those in the mixed salt test, but the thickness of the corrosion layer is relatively thinner and the size of sulfide is relatively larger. Combined with thermodynamics and microstructure analysis, it is clear that the alloy elements can react with solid Na2SO4 salt in the corrosion environment without SOx atmosphere.

It is very important to monitor the infection of Mycoplasma ovipneumoniae as a potential threat to the sheep industry. Southern Xinjiang is a major sheep breeding base in China, however, there is no relevant information concerning the infection of the region’s ovine stock with this bacteria at present. This study aimed to address this knowledge gap.

Atherosclerosis (AS) is a serious cardiovascular disease. Circular RNAs (circRNAs) play an important role in the progression of many diseases, including AS. However, the role of circ_0003204 in AS is not clear. Oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs) were used to construct an AS cell model in vitro. Cell viability was assessed using cell counting kit 8 (CCK8) assay. Flow cytometry and caspase-3 activity were used to measure cell apoptosis. The contents of inflammatory cytokines were measured using enzyme-linked immunosorbent assay (ELISA). Oxidative stress marker expression and cell injury marker activity were detected by their corresponding Assay Kits. Besides, the expression levels of circ_0003204, miR-330-5p, and toll-like receptor 4 (TLR4) were tested by real-time polymerase chain reaction (qPCR). The interaction between miR-330-5p and circ_0003204 or TLR4 was examined by dual-luciferase reporter assay and RNA pull-down assay. Western blot (WB) analysis was used to determine the levels of TLR4 protein and nuclear factor-kappa B (NF-κB) signaling pathway-related protein. Our data suggested that ox-LDL could suppress viability and promote apoptosis, inflammatory response, and oxidative stress in HUVECs. circ_0003204 was highly expressed in ox-LDL-induced HUVECs, and its silencing could inhibit ox-LDL-induced HUVECs injury. miR-330-5p could be sponged by circ_0003204, and its inhibitor could reverse the inhibition effect of silenced circ_0003204 on ox-LDL-induced HUVECs injury. Further, TLR4 could be targeted by miR-330-5p, and its overexpression could invert the suppression effect of miR-330-5p on ox-LDL-induced HUVECs injury. The activity of the NF-κB signaling pathway was regulated by the circ_0003204/miR-330-5p/TLR4 axis. Our results indicated that circ_0003204 silencing could alleviate ox-LDL-induced HUVECs injury, suggesting that circ_0003204 might be a novel target for AS treatment.

With the disclosure of ESG, the investment related to ESG disclosure has increased, and the trend of changes in intangible capital has shown an “inverted S-shaped” curve. The research shows that, in the initial stage of investment in ESG construction, new ESG investments increase intangible capital. With the increase in ESG investment and the advancement of time, the positive effect of the increase in ESG scores on intangible capital begins to appear and gradually offsets the cost of ESG investment. However, when the ESG score of a company is raised to a certain level, the marginal effect of continuing to increase ESG investment will reduce the increase in intangible capital.

The opposing roles of the central governments of China and Russia in the projects of “smart cities” continue to arouse interest in the academic world. This article compares and contrasts the roles that the central governments of China and Russia play in stimulating the development of smart cities. The influence of the concept of a smart city is quite wide. At the federal level, the concept allows the formation of a digital society, as well as a digital economy, which are priority areas for the country’s development in order to increase its economic indicators, in particular GDP. At the regional level, the concept allows for the comprehensive development of cities with the aim of ensuring a high standard of living in society as well as improving the efficiency of regional and municipal governance. Using a wide range of data, the paper offers an analysis of the practical differences between the two states. In addition, the document will consider proposals for a “smart city” put forward by the governments of the two countries, and draw conclusions about the significance of these differences in the success and functioning of “smart cities”.

With the advent of the big data era, user needs have become more and more diversified and personalized. These new user characteristics are important for the sustainable marketing of enterprises. With intensified competition, how to attract clients at minimal cost has become the primary concern for community e-commerce platforms or other e-commerce platforms. One of the best solutions is precision marketing, which is an important part of sustainable marketing. In this paper, a modified AISAS model is proposed for evaluating precision marketing effectiveness using data from a real-world community e-commerce platform. Based on face-to-face expert interviews and questionnaire surveys, an analytic hierarchy process (AHP) method is used to determine weights of different indexes adopted in the evaluation model and then quantify the precision marketing effectiveness of the e-commerce platform. The marketing results are then verified. We found that community e-commerce platforms’ marketing ought to be gentle and sustainable due to service area constraints or capacity limitations. The community e-commerce platform is more successful in attracting customers’ attention and interest from the marketing effectiveness. However, it is inadequate to rely on customers’ purchase and repeat purchase behaviors. Therefore, the precise selection of platforms is critical to the cultivation of customers’ loyalty and the increases in their products’ repurchase rate.

To understand the psychological process of patients with post-herpetic neuralgia (PHN) and provide references for the psychological management of PHN.
