The impact of environmental regulation on technology innovation is a hot spot in current research where a large number of empirical studies are based on Porter Hypothesis(PH). However, there are still controversies in academia about the establishment of "weak" and "narrow" versions of PH. Based on the panel data of application for patent of energy conservation and emission reduction(ECER) technology of Chinese city scale during 2008-2014, comprehensive energy price, pollutant emission, etc., mixed regression model and systematic generalized method of moments method were adopted, respectively,to study the impact of market-oriented and command-and-control policy tool on China's ECER technology innovation. The results show that the environmental regulation hindered the technological innovation in the immediate phase; however, it turned out to be positive in the first-lag phase. Hence, the establishment of "weak" PH is time-bounded. The command-and-control policy tool played a more positive role in promoting technological innovation in the first-lag phase than market-oriented policy tool. Therefore, "narrow" PH is not tenable. The reason is that the main participants of China's ECER technology innovation are state-owned companies and public institutions. Regionally speaking, the impact which command-and-control policy tool has on technological innovation at sight was nonsignificant in the eastern, the central, and the western regions of China whilst market-oriented policy tool had a negative effect. And market-oriented policy tool in the central region had strongest negative effect, which would diminish in the eastern region and become weakest in the western region. This was related to regional energy consumption level and the market economic vitality. 展开更多

By analyzing the problems which exist currently in the accident hidden dangers management of the coal mine, this paper proposed a new kind of management method--"simulating the market", in which an operation pattern of simulating the market to transact hidden troubles was constructed. This method introduces "Market Mechanism" into safe management, and adopts measurable value to describe the hidden dangers such as" human behavior, technique, environment, equipments etc.". It regards the hidden dangers as "the goods produced by labor" which are found out by the safety managers and the security inspectors, then sells as "commodity". By the process of disposing, counterchecking, re-selling, and redisposing. It forms a set of market-oriented closed-form management pattern of coalmine accident hidden dangers. This kind of management method changes the past traditional methods in which the wageworkers treat safety management passively, but to encourage and restrict them to participate in the check-up and improvement of the hidden dangers. 展开更多

The purpose of this study is to analyze the characteristics of the spatial distribution and change trend of the marketing level of stateowned land supply so as to provide policy recommendations. Method of spatial autocorrelation analysis is employed. The results indicate that the spatial layout of the land supply marketing level is generally dispersed,but it does assemble in some specific area. The correlation between the marketing level of state-owned land supply and the economic development is not statistically significant. But their relations fluctuate obviously. The overall marketing level of state-owned land supply is increasing and spatially concentrated. The expansion rate of marketing has decreased first and then increased and stabilized now. The high-value cluster center of marketing level of state-owned land supply exists all over the country; however the existence probability of the cluster is bigger in undeveloped areas. It is concluded that spatial autocorrelation analysis is a good method to quantitatively analyze the spatial variation of marketing level of state-owned land supply in China. To grasp the spatial and temporal variations of the marketing level of state-owned land supply is also good to enhance running of the state-owned land market. 展开更多

This paper aims to explore the effects of market-oriented reforms on industrial technology progress.Based on a theoretical analysis,we performed an empirical study with a marketization index and panel data of high-tech sectors in China.We found that market-oriented reforms had significantly propelled technology progress in China’s high-tech sectors,and the effects became more evident after China’s WTO entry.Market-oriented reforms induced technology progress by increasing capital allocation efficiency,R&D input,and technology diffusion.Among various aspects of market-oriented reforms,the institutional environment exerted the most significant effects,followed by the economy’s non-state sector,product market development,and factor market development;the government-market relationship index influenced technology’s progress the least.The effects are heterogeneous across sectors with different technology attributes and more significant for technology-intensive sectors.Our findings offer policy implications for China’s ongoing market-oriented reforms and policy design for technology progress in high-tech sectors. 展开更多

The construction of the market-oriented ecological compensation mechanism in China is complicated system engineering. China's ecological compensation funds are mainly derived from the public finance, lacking market-oriented operation. That not only increases the financial burden of the government, but also leads to the incomprehensive compensation scope. Moreover, China's ecological compensation lacks market mechanism so that it is difficult to set compensation standards and calculate offsets. This paper takes Gannan Tibetan Autonomous Prefecture as an example to analyze the market-oriented ecological compensation system of ethnic minority areas from the perspective of market economy, so as to provide a theoretical basis and a reference point for the establishment of efficient and reasonable ecological compensation mechanism and policies in ethnic minority areas and provide environmental protection for the sustainable development of economy and society of ethnic minority areas. 展开更多

Cardiovascular diseases(CVDs)remain the leading cause of morbidity and mortality worldwide,necessitating innovative diagnostic and prognostic strategies.Traditional biomarkers like C-reactive protein,uric acid,troponin,and natriuretic peptides play crucial roles in CVD management,yet they are often limited by sensitivity and specificity constraints.This narrative review critically examines the emerging landscape of cardiac biomarkers and advocates for a multiple-marker approach to enhance early detection,prognosis,and risk stratification of CVD.In recent years,several novel biomarkers have shown promise in revolutionizing CVD diagnostics.Gamma-glutamyltransferase,microRNAs,endothelial microparticles,placental growth factor,trimethylamine N-oxide,retinol-binding protein 4,copeptin,heart-type fatty acid-binding protein,galectin-3,growth differentiation factor-15,soluble suppression of tumorigenicity 2,fibroblast growth factor 23,and adrenomedullin have emerged as significant indicators of CV health.These biomarkers provide insights into various pathophysiological processes,such as oxidative stress,endothelial dysfunction,inflammation,metabolic disturbances,and myocardial injury.The integration of these novel biomarkers with traditional ones offers a more comprehensive understanding of CVD mechanisms.This multiple-marker approach can improve diagnostic accuracy,allowing for better risk stratification and more personalized treatment strategies.This review underscores the need for continued research to validate the clinical utility of these biomarkers and their potential incorporation into routine clinical practice.By leveraging the strengths of both traditional and novel biomarkers,precise therapeutic plans can be developed,thereby improving the management and prognosis of patients with CVDs.The ongoing exploration and validation of these biomarkers are crucial for advancing CV care and addressing the limitations of current diagnostic tools. 展开更多

For large-scale heterogeneous multi-agent systems(MASs)with characteristics of dense-sparse mixed distribution,this paper investigates the practical finite-time deployment problem by establishing a novel crossspecies bionic analytical framework based on the partial differential equation-ordinary differential equation(PDE-ODE)approach.Specifically,by designing a specialized network communication protocol and employing the spatial continuum method for densely distributed agents,this paper models the tracking errors of densely distributed agents as a PDE equivalent to a human disease transmission model,and that of sparsely distributed agents as several ODEs equivalent to the predator population models.The coupling relationship between the PDE and ODE models is established through boundary conditions of the PDE,thereby forming a PDE-ODE-based tracking error model for the considered MASs.Furthermore,by integrating adaptive neural control scheme with the aforementioned biological models,a“Flexible Neural Network”endowed with adaptive and self-stabilized capabilities is constructed,which acts upon the considered MASs,enabling their practical finite-time deployment.Finally,effectiveness of the developed approach is illustrated through a numerical example. 展开更多

Deep learning algorithms have been rapidly incorporated into many different applications due to the increase in computational power and the availability of massive amounts of data.Recently,both deep learning and ensemble learning have been used to recognize underlying structures and patterns from high-level features to make predictions/decisions.With the growth in popularity of deep learning and ensemble learning algorithms,they have received significant attention from both scientists and the industrial community due to their superior ability to learn features from big data.Ensemble deep learning has exhibited significant performance in enhancing learning generalization through the use of multiple deep learning algorithms.Although ensemble deep learning has large quantities of training parameters,which results in time and space overheads,it performs much better than traditional ensemble learning.Ensemble deep learning has been successfully used in several areas,such as bioinformatics,finance,and health care.In this paper,we review and investigate recent ensemble deep learning algorithms and techniques in health care domains,medical imaging,health care data analytics,genomics,diagnosis,disease prevention,and drug discovery.We cover several widely used deep learning algorithms along with their architectures,including deep neural networks(DNNs),convolutional neural networks(CNNs),recurrent neural networks(RNNs),and generative adversarial networks(GANs).Common healthcare tasks,such as medical imaging,electronic health records,and genomics,are also demonstrated.Furthermore,in this review,the challenges inherent in reducing the burden on the healthcare system are discussed and explored.Finally,future directions and opportunities for enhancing healthcare model performance are discussed. 展开更多

BACKGROUND Laparoscopic hepatectomy has been widely accepted for the treatment of liver tumors.Compared with open surgery,it provides a reduced hospital stay,less intraoperative blood loss,less trauma,and fewer incisional infections,without affecting tumor outcomes.However,lesions in the right lobe of the liver are deep and obstructed by the ribs,making exposure difficult and increasing the degree of surgical difficulty;thus,liver tumors in the deep right lobe pose technical challenges in standard laparoscopic surgery.AIM To investigate the safety and efficacy of laparoscopic retroperitoneal partial hepatectomy for liver tumors.METHODS The clinical data of 72 patients who underwent laparoscopic retroperitoneal partial hepatectomy for liver tumors between January 2018 and December 2024 at the First People’s Hospital of Yunnan Province were analyzed.Of the 72 patients included,34 were male and 38 were female,with ages ranging from 34 years to 72 years(median age,45 years).The tumors were all located in the right lobe of the liver,with 30 cases in segment S6,27 cases in segment S7,and 15 cases in segment S8;the mean tumor diameter was 7.5±3.4 cm.The postoperative tumor indices,liver function,and postoperative complications were analyzed to evaluate the clinical efficacy of laparoscopic partial hepatectomy via the retroperitoneal approach.RESULTS The surgeries were successfully completed in all patients,and conversion to open surgery was required in 10 patients.The mean operative time,blood loss,drain retention time,and length of postoperative hospital stay were 140±30 minutes,150±46 mL,3.8±1.2 days,and 8.3±5.3 days,respectively.Liver function tests returned to normal in all patients within two weeks of surgery.Fifteen patients developed atelectasis and pleural effusion and were managed with incision and drainage and antibiotics.Two patients developed uncomplicated minimal ascites,and the remaining patients had no perioperative complications,such as abdominal hemorrhage,infection,liver failure,bile leakage,and other adverse events.All patients were successfully treated.CONCLUSION Laparoscopic retroperitoneal partial hepatectomy is a safe and effective approach for right hepatic space-occupying lesions,particularly in segments S6,S7,and S8,with fewer postoperative complications,less trauma,and faster recovery times.This procedure provides a new surgical access for resection of deep tumors in the right lobe of the liver and has clear clinical implications. 展开更多

In response to the common problems in college English writing teaching,such as the separation of learning and application,students’low interest in writing,and difficulties in expression,this paper,based on the theoretical framework of the production-oriented approach(POA)proposed by Professor Wen Qiufang,designed and implemented a set of IELTS writing teaching plan.This plan takes“motivating,enabling,and assessing”as the core teaching process,and selects typical IELTS argumentative essay topics(such as food diversity)to create real communication scenarios.In the motivating stage,diverse inputs are used to stimulate students’interest and expose their language weaknesses;in the enabling stage,language knowledge,viewpoint generation,and text structure are focused on for targeted input and training;in the assessing stage,a combination of teacher-student cooperation and peer evaluation is adopted to guide students to identify and correct deficiencies in language use.The research results show that the POA model can effectively enhance students’writing interest,active learning awareness,and writing ability,particularly in overcoming vocabulary poverty and material shortages,as well as improving language accuracy and expression richness.This provides an operational theoretical basis and practical path for improving the teaching effect of IELTS writing. 展开更多
