A new method was proposed for point-of-care testing (POCT) of immunosuppressants in blood using thin-layer paper spray ionization and a miniature mass spectrometer. The aluminum thin-layer plate was used as paper spray substrate, and cut into an equilateral triangle. Aliquots of 10 μL blood sample were loaded on the aluminum thin-layer plate, and then 20 μL methanol was dropped as elution/spray solvent. The tip of the triangular plate was placed 1.0 cm in front of the discontinuous atmospheric pressure interface (DAPI) of the miniature mass spectrometer. When the spray voltage was applied, the sample was eluted from the triangular plate and formed paper spray ionization at the tip. Coupled with the miniature mass spectrometer, five immunosuppressants were detected under negative ion mode. The precursor ions ［M-H］- of tacrolimus, sirolimus, everolimus, ciclosporin A, and mycophenolic acid are m/z 802.6, 912.6, 957.1, 1 200.8, 319.1, and product ions are m/z 560.2 and 604.3, m/z 590.3 and 321.2, m/z 590.3 and 365.2, m/z 1 088.8, m/z 287.4 and 275.1, respectively. Based on the observed signal-to-noise ratio (S/N) of the most intense tandem mass spectrometry (MS/MS) fragment peaks and using the S/N=3 and 10 as the criteria, the limits of detection (LODs) and quantitation (LOQs) are estimated to be 0.5-5 mg/L and 1-10 mg/L, respectively. The internal standard method was used for quantitative analysis, and indapamide was used as the internal standard compound. Sufficient linearity for each analyte is obtained with the correlation coefficients (r) greater than 0.99. The proposed method displays good recoveries in the range of 91.0%-114.3% with the relative standard deviations (RSDs) less than 8.4%. Moreover, the developed method was used for the analysis of blood samples, which spiked with tacrolimus, sirolimus, everolimus, cyclosporine A and mycophenolic acid at the concentration of 100 mg/L. The analytical results demonstrated the consistency between the proposed method and the traditional liquid chromatography-mass spectrometry (LC-MS) method. The entire analysis procedure can be completed within 1 min. The proposed method is simple, fast, accurate, efficient, and suitable for POCT of immunosuppressants in blood.

BackgroundIn recent years, the rising number of e-cigarette users among adolescents and the surging cases of lung injury related to e-cigarette use have attracted the attention of researchers in various fields.ObjectiveTo identify the research hotspots and trends of e-cigarette or vaping product use associated lung injury (EVALI) worldwide from 2013 to 2022 by bibliometric and visual analysis. MethodsWeb of Science Core Collection was selected to obtain literature related to EVALI from 2013 to 2022 across the world, statistics were calculated by country/region, institution, author, journal, cited literature, keyword, etc. CiteSpace 6.2.R1 was used for visual analysis to draw diagrams of publication trend, author cooperation network, co-citation clustering time distribution, and keyword cluster. ResultsA total of 888 EVALI-related papers published between 2013 and 2022 were retrieved. The number of publications was gradually increased, with a significant increase in 2020 and a decrease from 2021, but the number of citations was increased year by year. The most active country was the United States (631 articles). European and American countries cooperated closely and the centrality was prominent. Among the publishing institutions, the University of California system topped the list with 103 articles. Rahman I (27 articles) published the most articles and had a high degree of centrality; Goniewicz M L was the most cited author; and the network analysis diagram showed relatively weak collaboration between authors. The American Journal of Respiratory and Critical Care Medicine was the journal with the highest number of publications (94 articles). The top 5 cited articles were all cited more than 300 times. The leading high-frequency keywords of EVALI-related studies were nicotine (149 times), exposure (118 times), and oxidative stress (80 times). The cluster of key nodes in the co-citation network and the clustering time distribution diagram indicated youth e-cigarette addiction received widespread attention from society. From the top 25 keywords with the strongest bursts, the focus of research on the pathogenesis of EVALI gradually shifted from the oxidative stress damage associated with e-cigarette vapor to the oxidative effect of flavoring chemicals in the process of lung injury. The current research interests in this field were mainly the mechanisms of various chemicals in e-cigarettes and the heating elements that led to damage to the lungs. ConclusionEVALI is receiving continuous attention from researchers in government, medical institutions, and other organizations. A variety of e-cigarette ingredients such as flavoring chemicals may lead to varying degrees of cytotoxicity, inflammation, and lung damage. However, the pathophysiology of EVALI remains unclear. In the future, more Chinese scholars should be encouraged to participate in this field.

Based on the selective quenching effect of the flavonoid rutin on the fluorescence of carbon dots prepared by asparagine pyrolysis, a method for rapid detection of rutin content in the flower buds of Sophora japonica by using chitosan-based carbon dot paper chip was developed. A filter paper was immersed in the casting solution of carbon dots and chitosan. After drying, a carbon dot chitosan film was formed on the surface of the filter paper, so that the chitosan-based carbon dot paper chip was obtained. After samples were dripped on the chip, chromogenic reaction occurred uniformly within a limited region, and pictures were taken under an ultraviolet (UV) lamp at 365 nm for analysis of the red (R), green (G), and blue (B) values of the colored spots in order to optimize the preparation conditions and detection conditions. The results showed that the optimal conditions were as follows: chitosan concentration of 20 mg/mL, carbon spot concentration of 1.0 mg/mL, 50% ethanol as sample solvent, and reaction time of 20 min. Under these conditions, the difference (ΔG) in G-value between sample and solvent spots had a linear relationship with rutin concentration (C) in the range of 4 to 120 mg/mL. Using this method, the average contents of rutin in the flower buds of S. japonica from three batches were determined to be 23.85%, 22.83% and 20.30%, the average relative standard deviations (RSDs) were 6.1%, 5.6% and 6.7%, and the recoveries were 91.27% to 107.5%, which were close to the results of high performance liquid chromatography (HPLC). The proposed method is simple and rapid, and can be used for rapid on-site determination of rutin content in the flower buds of S. japonica.

Results of academic research require publication and need to be reviewed by peers before they can contribute to the existing body of knowledge. Among the various means of publishing research findings, researchers may, according to past academic practices, first present their research results in conferences, seminars or symposiums, and then submit their results to journals for publication. Hence, the issue of “extended publication”, where conference papers are revised and submitted to journals, has gained attention in the library and information science community. This study collected public documents on the Internet and applied document analysis to examine the ethical considerations regarding such extension practice. First, this research reviewed the basic principles of research integrity and responsible behavior. Secondly, this research listed several types of violation related to research paper writing and submission, and studied the guidelines established by both domestic and foreign academic organizations, publishers, and journals. The findings of the research were used to provide specific recommendations on the best practices for extending conference papers to journal articles.

“Lab on paper” is a paper-based microanalytical system with unique advantages such as high sensitivity, low cost, portability, and mass production, which breaks through the limitations of traditional detection technologies and shows great potential in the field of rapid on-site food detection. In this paper, the typical “labs on paper”, including chromatographic paper, chemical test chip, lateral flow assay (LFA), microfluidic paper-based analytical devices (μPADs), and synthetic biological paper, are systematically reviewed. Special emphasis is put on the application of “lab on paper” in the field of food detection. Finally, the advantages, challenges, and future prospects of paper-based analytic methods are discussed, which may provide theoretical support for better application of “lab on paper” in the field of food detection.

BackgroundBy analyzing the publication of scientific and technological papers of the provincial centers for disease control and prevention (CDCs) in China, we can understand their scientific research strength, dominant disciplines, research hotspots, and talent development, which is conducive for further optimizing the scientific research construction of the disease control system.ObjectiveTo conduct a bibliometric analysis and draw a visual map of the Chinese Science Citation Database (CSCD) sourced papers published by 31 provincial CDCs in China from 2011 to 2020, to understand the scientific research status of China's provincial CDC system in the past ten years.MethodsIn April 2021, China National Knowledge Infrastructure was used to retrieve CSCD sourced papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in China as the primary unit from 2011 to 2020, and finally 5231 CSCD papers were included. Bibliometric analysis indicators include number of CSCD papers published and financial support rate, proportion of CSCD papers to total Chinese papers, distribution of CSCD papers published in high-volume journals, and number of papers for a specific CDC that their first authors affiliated with. Citespace 5.8.R1 software was used to draw author's cooperation network map, keyword co-occurrence map, keyword clustering information table, and keyword emergence map.ResultsThe number of CSCD papers published every year showed a stationary trend, and the total funding rate was 61%, showing an year-by-year upward trend (increased from 49.3% in 2011 to 68.7% in 2020). Jiangsu Province, Fujian Province, and Beijing CDCs ranked the top three in the total number of CSCD papers contributed by a specific CDC. The Chinese Journal of Epidemiology, Chinese Journal of Public Health, Chinese Journal of Zoonoses, Chinese Journal of Preventive Medicine, and Chinese Journal of Endemic Diseases were the top five high-volume journals. The top three authors of CSCD papers (counted as co-authors) were Xu Bianli of Henan Provincial Center for Disease Control and Prevention (110 papers), Yan Yansheng of Fujian Provincial Center for Disease Control and Prevention (72 papers), and Wang Quanyi of Beijing Center for Disease Prevention and Control (71 papers), and they studied the epidemiology of parasitic diseases and infectious diseases, the prevention and treatment of natural epidemic diseases and AIDS, and the epidemiology of infectious diseases, respectively. The keyword co-occurrence map showed that AIDS, zoonotic diseases, hand-foot-mouth disease, etc. (frequency ≥90) were the key research directions of provincial CDCs in the past ten years. The keyword clustering categories were closely related, although there were subtle differences, the topics focused on virus and chronic disease research. The keyword emergence results suggested that the frontiers of research had gradually shifted from infectious diseases such as enterovirus, hantavirus, and Zika virus to food-borne diseases and chronic non-communicable diseases such as tumors and senile diseases over time.ConclusionThe number of papers issued by the provincial CDCs in China in the past ten years has shown an overall steady and rising trend. The leading themes of researchers and institutions are infectious diseases, parasitic diseases, etc., while food-borne diseases and elderly diseases are the hot frontiers.

An efficient surface enhanced Raman scattering(SERS)substrate was prepared by screen printing silver ink on drawing paper, white card paper and coordinate paper. The results showed that silver film/drawing paper represented the best SERS activity, followed by silver film/white card paper and silver film/coordinate paper. The minimum detection limits for crystal violet were 10-8, 10-7 and 10-7 mol·L-1, respectively. In addition, ten different positions were randomly selected on the same silver film/drawing paper surface, and the relative standard deviation values of the peak intensitiesat 913, 1 179 and 1 620 cm-1 were 13.2%, 12.5% and 10.6%, respectively, which indicated outstanding uniformity.

This study used bibliometrics to analyze the characteristics of funded papers in the social sciences in Taiwan from 2015 to 2019, including the number of funded papers, funded paper ratio, document types, fields, type of publishing organizations, journal impact, and paper citation impact. The results indicate that the number of funded papers and the funded paper ratio of SSCI papers from Taiwan have both increased. In addition to articles and reviews, conference papers are a major type of funded paper for local SSCI papers. In terms of fields, the nontraditional social sciences, such as environmental sciences, psychiatry, and public/environmental & occupational health, have a particularly high funded paper ratio. However, the number of funded papers and funded paper ratio is the highest in the field of education & educational research. The fields of economics, management, and business have a large number of funded papers but a low funded paper ratio. Universities are the main funded institutions, but hospitals have the highest funded paper ratio. Funded papers tend to have higher paper citation impacts. Therefore, funding positively affects the productivity and impact of SSCI papers from Taiwan. (Article content in Chinese with English extended abstract)

BackgroundThe COVID-19 pandemic hints at the importance of modernizing disease control system. To understand the scientific research strength of our country's disease control system in recent years is conducive to formulating more targeted policies or measures to promote the modernization of the disease control system.ObjectiveTo understand the scientific research strength and research hotspots of China's provincial-level centers for disease control and prevention (CDCs) from 2011 to 2020, and provide evidence for the development of scientific research work, discipline construction, and talent team construction in CDCs in the future.MethodsThe Science Citation Index Expanded (SCIE) and Social Science Citation Index (SSCI) of the Web of Science Core Collection were used to retrieve SCI-indexed English papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in our country from 2011 to 2020, and to screen literature with provincial CDCs as the first affiliation for bibliometric analysis and visual analysis. Bibliometric analysis included the SCI-indexed publications of different provincial CDCs (as co-affiliation and the first affiliation), the number of SCI-indexed papers published by provincial CDCs (as the first affiliation) and funding rates by years, the high-frequency authors of SCI-indexed papers published by provincial CDCs (as the first affiliation) and their distribution, and the characteristics of the journals. Visual analysis software Citespace 5.8.R1 was used to draw keyword co-occurrence maps, cluster information tables, and emergence maps to provide information on research hotspots and their evolution.ResultsFrom 2011 to 2020, the number of SCI-indexed papers from 31 provincial CDCs was 8420 (including co-affiliation), of which 2060 papers listed provincial CDCs as the first affiliation. The provincial CDCs of Zhejiang, Jiangsu, Shanghai, Beijing, Shandong, and Guangdong were the leading six institutes in terms of the total number of SCI-indexed papers contributed as co-affiliation or the first affiliation. There was a large gap in the total number of SCI-indexed papers among the provincial CDCs. The highest total number of SCI-indexed papers contributed by provincial CDCs as the first affiliation was Zhejiang CDC (448 papers), while the lowest number was Xinjiang CDC (only 1 paper). From 2011 to 2020, the total number of SCI-indexed papers contributed by the 31 provincial CDCs as the first affiliation showed an overall increasing trend. Except for 2011, which was 63.1%, the funding rates in other years exceeded 70%. In terms of high-frequency authors, 13 first authors published ≥10 SCI-indexed papers: Zhang Yingxiu from Shandong CDC had the highest number of SCI-indexed papers (47), followed by Hu Yu from Zhejiang CDC. Zhejiang, Jiangsu, Beijing, Guangdong, Shanghai, and Shandong still ranked the top six of ≥4 first authored-SCI papers. In terms of journal characteristics, the top 20 journals with the highest number of SCI papers published a total of 862 papers, accounting for 41.8% (862/2060), and PLOS ONE ranked the first (188 papers). The research hotspots were mainly concentrated in the fields of infection, child health, and epidemiology. The main keywords of the first three cluster categories were related to the research fields of adolescent overweight and obesity, HIV, and vaccine immunity. The results of keyword emergence showed that research hotspots shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.ConclusionThe past ten years have witnessed increasing numbers of SCI-indexed papers published by provincial CDCs in our country and a stubbornly high funding rate. However, the gap among the provincial CDCs is still large seeing that economically developed eastern provincial CDCs published more SCI-indexed papers. Research hotspots have gradually shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.

Naturally-occurring precipitate of traditional Chinese medicine (TCM) is generally considered to be a common phenomenon. The formation of naturally-occurring precipitate originates from the interactions among different chemical components during the decoction process. Previous literature has reported the existence of naturally-occurring precipitate in Sini decoction. In this study, seven pairs of acid-base non-covalent complexes in Sini decoction were characterized using cold spray ionization-mass spectrometry (CSI-MS). The CSI device was built in house, where a stream of nitrogen gas was cooled by liquid nitrogen and used as the sheath gas, providing low-temperature ionization conditions for the MS analysis of the acid-base non-covalent complexes. The gas pipeline was equipped with a valve to regulate the nitrogen flow rate. Data acquisition was carried out using a quadrupole/Orbitrap high-resolution mass spectrometer operated in both full-scan MS and collision-induced dissociation MS/MS modes. Experimental results showed that the seven pairs of acid-base non-covalent complexes were unequivocally observed in positive and negative ionization modes. Mass spectrometric responses for each acid-base non-covalent complex varied with different chemical structures, binding abilities and ionization efficiencies. A representative pair of acid-base non-covalent complex (enoxolone/benzoylmesaconine) was selected to investigate the influence of the acid-base concentration ratio (3∶1, 2∶1, 3∶2, 1∶1, 2∶3, 1∶2, 1∶3) on the binding stoichiometry. The enoxolone/benzoylmesaconine complexes with the binding ratios of 1∶1, 1∶2, 2∶1 were observed, among which the mass spectrometric peak of the 1∶1 binding ratio was the most intensive. The non-covalent interactions of the representative enoxolone/benzoylmesaconine complex were analyzed using isothermal titration calorimetry (ITC) and computational chemistry. The thermodynamic parameters were obtained in the ITC experiment. In comparison with entropy change, the contribution of enthalpy change to Gibbs free energy was more significant, indicating that Van der Waals force and hydrogen bonding might be the main driving force in the formation of acid-base non-covalent complexes. This result was further confirmed by the docking model and simulation results of computational chemistry. Multiple hydrogen bonds derived from the interactions between specific atoms locating in the acid and base compounds promoted the self-assembly process. Moreover, Van der Waals attraction or repulsion force was generated between the C and H atoms at different positions, which in conjunction with hydrogen bonding interaction drove the formation of the acid-base non-covalent complexes. This study provides theoretical foundation and technical instruction for exploring the formation mechanism of naturally-occurring precipitate in Sini decoction.

The efficient AgNPs/photographic surface enhanced Raman scattering(SERS) paper substrate was prepared by inkjet printing silver ink on photographic paper, for which the wettability and surface morphology were represented by contact angle meter and scanning electron microscope(SEM). The application of AgNPs/photographic paper for detecting pesticide residues was studied by simulating the residual states of thiram on peels and in juice. It was found that thiram molecules mixed in juice or on peels could be directly recognized by the substrate without any treatment. The minimum detection concentration of thiram in juice was 0.024 mg∙L-1, in which a good linear relationship between characteristic peak intensity and concentration was obtained The detection limit of thiram on the two peels was both 0.25 ng∙cm-2. In addition, ten spots were selected from the same substrate to study the uniformity randomly. The relative standard deviations of the characteristic peak intensities at 1 142 and 1377 cm-1 of thiram were 7.8% and 5.7%, respectively. The results showed that AgNPs/photographic paper substrate had great potential in the detection of pesticide residues.

An automatic recognition system of paper currency serial numbers of the Republic of China was realized by deep learning in this paper. Firstly, the characters of paper currency serial numbers of the Republic of China were extracted and segmented. Secondly, pre-processing for each character was conducted and the blank character zone was clipped in order to normalize the character size.Lastly, the characters were recognized by the convolutional neural network.The experimental results showed that the paper currency serial number recognition system proposed in the paper could reduce the workload of manual entry while there were stains and wrinkles existing on the paper currency.The recognition accuracy of a single character could reach more than 99.99%.

The purpose of this study was to investigate the extended publishing of conference papers in the field of management. The sample examined consisted of a total of 2,427 conference papers that were published in 2011 in nine international conferences spanning four academic fields, which were marketing, production and operations management, transportation management, and information management. This study adopted bibliometrics to analyze the extended publishing rate of the original conference papers, the document types of the extended publications, and the publication lag from the original conference papers to extended versions publishing. The differences between the originals and extended publications were also compared, including the changes in authorship, references, the length of articles, and the number of tables and figures. The results of the study reveal that the average extended publishing rate of the original conference papers was 17.06%, with journal articles being the major category. The average time lag for extended journal articles publishing was 27.99 months, and for submission was 14 months. This study suggested that the academic publishers provide relevant publication policy for extended publication. The journal editors and researchers should follow the guideline for submission and the editorial policy to avoid academic misconduct.

Brenda Dervin presented a paper in 1983 titled “An Overview of Sense-Making Research: Concepts, Methods and Results to Date” at a conference. She presented the “Sense-Making Methodology (SMM)” in the 1983 paper with the introduction of its core concepts, methods, and applications. SMM is a user-centered theory for methodology and has been widely applied to a wide range of fields. The findings of this study show that the 1983 paper has a longterm influence on other research articles and its influence has expanded into more disciplines and topics over time. Most of 283 articles citing the 1983 paper were information behavior articles published in journals of library and information science. This study contributes to confirm that the primary influence of this 1983 paper was established by a few concepts related to SMM. Not all three basic concepts constructing the SMM, “gaps”, “situations”, and “uses”, were the most influential concepts in terms of number of citation contexts. “Gaps” was the most frequently cited concept related to SMM (17.5%), closely followed by “sense-making/nonsense-making (17.3%)”. However, “SMM” was the most influential concept in terms of number of research topics of citing articles.

In recent years, some scholarly journals have indicated that they accept rewritten or extended version of a conference paper as long as new content are added to the journal article manuscript and that the original conference paper is included in the references. The extended publishing of conference papers now becomes topic worthy of investigation. This study analyzed the extended works of the conference papers from three major conferences in the fields of information management, i.e., Association for Computing Machinery (ACM)’s ACM Conference on Electronic Commerce (ACM EC), ACM Conference on Knowledge Discovery and Data Mining (ACM KDD), and ACM International Conference on Information and Knowledge Management (ACM CIKM). Papers from the 2011 meetings were used as the sample to understand to what extent conference papers have been extended into journal articles and other forms and the lag between conference and journal publishing. It also examined the differences between the conference papers and their extended versions (i.e., journal papers) by comparing the changes in authorship, references, article length, tables, and figures. It reveals the current practices of extending conference papers for journal publishing in the information management fields and may help us understand the contemporary scholarly publishing behavior.

The study utilizes bibliometrics to explore papers and patents in the field of fuel cell to examine the scientific and technical development in the area. The research data were retrieved from the WOS database and USPTO patent data from the period between 1991 and 2010, which consists of 20,758 papers and 8,112 patents. The authors analyzed numbers of papers and patents to examine the trends in the papers and patents in different countries, organizations and individuals. The results indicate upward growth in both papers and patents in fuel cell, with a higher growth rate for papers. The study shows that major paper and patent output are concentrated in a small number of countries. An imbalance exists between the number of papers published and the patents granted in organizations. The organizations that published papers and patents vary in type and category. Very few individual researchers are able to produce high numbers of both papers and patents.

To automate the process of paper reviewer recommendation, this work evaluates four kinds of paper representations, which include full text, abstract, title, and author defined keywords. To match reviewers with papers, this work evaluates seven scoring methods including three topic-based methods from OpenConf, a popular online submission system with source, and four similarity-based methods from the vector space model of traditional information retrieval. The results of the 28 experiments show that recommendation methods based on the vector space model are better than the three topic-based methods of OpenConf in most document representations. Among them, the abstract paper representation combined with cosine similarity matching measure has the highest average precision.

Japan’s detainment of Chinese fishing boats in 2010 and purchase of China’s Diaoyu Islands in 2012 tremendously harmed diplomatic relations between China and Japan, and had a negative impact on bilateral trade. This paper aims to analyze the impact of China-Japan relations and China’s participation in the Japan-centered East Asian production network on China’s export quality. The empirical research results based on the trade data of the mechanical and electrical industries indicate that China’s participation in the Japan-centered triangle trade enhances the quality of Chinese mechanical and electrical exports, and China should continue to strive for its integration into the Japan-centered East Asian production network.

Paper-cut is not simply a form of traditional Chinese folk art. Lucky motifs developed in paper-cut certainly acquired profound cultural connotations. As paper-cut is a time-honoured skill across the nation, interpreting those motifs requires cultural receptiveness and anthropological sensitivity. The author of this article analyzes examples of paper-cut from Northern Shaanxi, China, to identify the cohesive motifs and explore the auspiciousness of the specific concepts of Fu, Lu, Shou, Xi. The paper-cut of Northern Shaanxi is an ideal representative of the craft as a whole because of the relative stability of this region in history, in terms of both art and culture. Furthermore, its straightforward style provides a clear demonstration of motifs regarding folk understanding of expectations for life.

本研究以電子與電機產業為例,從其發明專利產量與科學論文產量的觀點探討科學與技術之關係。先前的研究多數透過對技術專利與科學文獻之間的引用來探討關於科學與技術的連結,但這樣的角度僅能呈現其相互影響的部分面向。因此本研究選擇以電子與電機產業專利表現極佳的20家世界知名公司為例,從同一個公司之專利產量與科學文獻產量的角度切入,探討科學與技術兩者之間的關連,並分別從其被引用狀況,分析企業產出專利與發表科學論文後所造成的影響程度。此外本研究也分析各公司的技術週期時間(TechnologyCycleTime,TCT),探討TCT與Patent-PaperRatio之間的關連,並改良即時影響指數(ModifiedCurrentImpactIndex,ModifiedCII)的計算方法使其同時適用於專利與論文,進而比較各公司的專利與論文之即時影響指數。其中發明專利與科學論文分別檢索自USPTO與WoS資料庫,於1989年至2008年間之資料。研究結果顯示,雖然近20年來電子與電機領域的科學論文成長幅度比技術專利大,但該領域中技術專利表現最優秀的20個公司的科學論文發表狀況與產生的影響力卻與其專利數量與影響力之間關連不顯著。本結果對於電子與電機領域之公司在技術與科學之間的連結關係提供一項新的實務證據。This study investigates the relation between production of utility patents and scientific papers in the electrical and electronic (E&E) industry. Unlike most prior researches delving into the link between science and technology through patent citations and paper citations, this article takes top 20 companies in the E&E industry as an example to examine the link between science and technology in terms of the productivity of patents and papers in one company. It also probes into patent citations and paper citations respectively and its consequences. Furthermore, this approach analyzes the link between Technology Cycle Time (TCT) and Patent-Paper Ratio (PtPR) and adopts the modified calculation, Modified Current Impact Index (Modified CII), to fit patents as well as papers. The source data are retrieved from top 20 companies’ patents and papers granted by the USPTO and covered in WoS database for the period of 1989-2008. Results from this analysis demonstrate that there is little connection between productivity and impact of papers and patents of these top 20 companies. These findings provide new empirical evidences about the linkage between technology and science at E&E industry level.

This paper discusses the Mr. Wang Lansheng's arguments about the origin of petroleum. It is well known that metal elements and their isotopes can be combined with organic compounds to form coordinating ions or complex compounds, which can be applied to petroleum tracing and isotopic dating. The Fischer-Tropsch reaction can synthesize different kinds of hydrocarbons (including crude oils), under different catalysts, higher temperatures and pressures. Daqing's exploration shows that abiogenic gas not only is existent, but also can form big gas reservoirs, such as the Xincheng Gas Pool. In the Tarim Basin, the Silurian bitumen whose reserves are 917.8×108t was generated by inorganic reaction rather than by organic matter. Abiogenic oil and gas were also found in meteorites and in continental scientific drillings. Some other topics related to the origin of petroleum are also discussed. According to the inorganic origin theory of petroleum, some exploration targets are presented in this paper. Key words: inorganic origin, metal isotope, Fischer-Tropsch reaction, exploration target

The growth in popularity of the World Wide Web has dramatically changed the way undergraduate students conduct information searches. The purpose of this study is to investigate what core quality criteria undergraduate students use to evaluate Web resources for their class papers and to what extent they evaluate the Web resources. This study reports on five Web page evaluations and a questionnaire survey of thirty five undergraduate students in the Information Technology and Informatics Program at Rutgers University. Results show that undergraduate students have become increasingly sophisticated about using Web resources, but not yet sophisticated about searching them. Undergraduate students only used one or two surface quality criteria to evaluate Web resources. They made immediate judgments about the surface features of Web pages and ignored the content of the documents themselves. This research suggests that undergraduate instructors should take the responsibility for instructing students on basic Web use knowledge or work with librarians to develop undergraduate students information literacy skills.

The cell-free biosensor is a tool designed to detect trace substances based on a cell-free system, which solves the problems of the traditional cell-based biosensor including having no ability to detect toxic substances, long response time, being controlled by living cells, and inconvenient operation. In recent years, cell-free biosensors have attracted extensive attention for their wide detection range, fast response speed, high sensitivity and portability. In this paper, the construction and characteristics of different types of cell-free sensors are reviewed. In addition, their applications in the detection of metal ions, pesticide residues and veterinary drug residues are introduced, and future prospects also are discussed.

Due to the high viscosity and bulk complexity of crude oil samples, it poses a grand challenge to determine hydrogen sulfide (H2S) in them. Although many methods have been developed for the analysis of H2S in complex systems, these methods generally have complex processes, large analysis error and low sensitivity. In the study, based on the reaction between triazine and H2S by generating thiadiazine, a small volume of complex crude oil sample was introduced directly into a triazine solution using acetonitrile as solvent for transferring H2S into detectable species by organic mass spectrometry. The experimental parameters of solution composition, acetic acid content, reaction time and reaction temperature were optimized, and the method of paper spray ionization-mass spectrometry (PSI-MS) was established for rapid analysis of H2S in complex crude oil samples. An optimal performance was achieved when the reaction of triazine and H2S was carried out at 30 ℃ for 2 h with acetonitrile containing 0.1% acetic acid as solvent. The standard curve for the quantitative analysis of H2S was constructed according to the linear relationship between MS signal intensity of resulting thiadiazine and the concentration of H2S, which was applied for actual crude oil samples from different sources. The results showed that the linear range and the limit of detection (LOD) were 0.1-1 000 μg/L and 0.041 μg/L with intra-day precision of 3.04% and inter-day precision of 3.18%, respectively. The PSI-MS was also employed to determine H2S in different actual crude oil samples, and the spiked recovery was 91.7%-103.5% with relative standard deviation (RSD) of 1.2%-4.5%. This method has the advantages of easy operation, low cost, high sensitivity and less contamination to mass spectrometer, which is promising for the direct and fast analysis of H2S in complex crude oil samples.

Detection of uric acid is crucial for real-time monitoring of human health. In this work, a method of portable scanner-based quantitative detection of uric acid with a smartphone was developed, meanwhile, a filter paper chip was designed and fabricated for the detection process, which provides an on-site, fast, and accurate measurement of the uric acid in human blood serum. The limit of detection was 0.8 mg/dL, and the detection results of human serum samples showed good agreement between the spectrophotometric method and the proposed one. This method does not require complex operations or expensive instruments, which is suitable for resource-limited areas, users’ home, as well as on-site detection, with wide applications and broad market prospects.

In order to promote the transformation and development of China’s economy and cope with the realistic challenges posed by the global economic recession and slowing domestic economic growth, the Fourth Session of the 12th National People’s Congress adopted a strategic resolution on developing the “new economy” and fostering new drivers of growth. Chengdu, capital of Sichuan province, is one of the cities in China which firstly begin to carry out the layout of the new economy development. While achieving results, it also faces many troubles due to its insufficient cognition of the connotation, definition, and path of the “new economy.” The paper is based on a theoretical study in combination with the new economic development of Chengdu’s five new paths, to analyze the concept and connotation of the “new economy.” It also analyzes from the perspective of higher dimensional reconstruction and new strategic path of economic development, in order to add some insights to the theorectical study and to promote better strategic value of the new economy.

This paper introduces three current major university ranking systems. The Performance Ranking of Scientific Papers for World Universities by Higher Education Evaluation and Accreditation Council of Taiwan (HEEACT Ranking) emphasizes both the quality and quantity of research and current research performance. The Academic Ranking of World Universities by Shanghai Jiao Tung University (ARWU) focuses on outstanding performance of universities with indicators such as Nobel Prizewinners. The QS World University Ranking (2004-2009) by Times Higher Education (THE-QS) emphasizes on peer review with high weighting in evaluation. This paper compares the 2009 ranking results from the three ranking systems. Differences exist in the top 20 universities in three ranking systems except the Harvard University, which scored top one in all of the three rankings. Comparisons also revealed that the THE-QS favored UK universities. Further, obvious differences can be observed between THE-QS and the other two rankings when ranking results of some European countries(Germany, UK, Netherlands, & Switzerland) and Chinese speaking regions were compared.

Due to the tremendous increase and variation in serial publications, faculties in university departments are finding it difficult to collect, generate and update their departmental core article ranked lists regularly and accurately. In addition, both students and researchers are finding it difficult to find and study the most significant papers for their departments or interested journals. Furthermore, editors want to trace and analyze the more highly cited articles published in their journals over different time spans. Therefore, the evaluation of a departmental and journal core article ranked list is an important task for faculties, students and editors. In this study, a Computer-Aided Paper Bibliometric System was implemented and four article citation ranking indicators (RCC, TCC, R/T PI and R/T CH) were proposed in order to generate a departmental and journal core article ranking list. These four indicators were designed to satisfy different audiences’ requirements. Four departments and ten journals were taken as samples, with a Department of Information Management and journal of MIS Quarterly as the major one. Several citation patterns were found. All Turning Points (TP) were located at the 4th segment (TP Site: 0.28) for all departments and journals by the TCC indicator. Through the RCC indicator, TPs from different departments or journals were classified into two types. The TP site of Type I was 0.07 and Type II was 0.14. Both RCC and TCC also have their own similar scatter charts. These patterns could be helpful in deciding the core article area or evaluating the experiment results. After comparing these four indicators via the Coefficient of Correlation, both RCC and TCC can obtain more than 0.5 and 0.9 correlation factors with their own extended indicators. The experimental results show that (TCC, TPI, TCH) and (RCC, RPI, RCH) were measured to be at an acceptable level.

Hyperuricemia (HUA) is a purine metabolism disorder caused by the imbalance between uric acid production and excretion, which, when severe, can lead to gout and renal function damage. At present, the prevalence of HUA/gout is increasing yearly in China and the HUA/gout patients are becoming younger and younger. Recent studies have shown that the intestinal flora of patients with HUA/gout is imbalanced when compared with that of healthy people, and different dietary patterns can affect the level of uric acid by adjusting the intestinal flora. This paper elaborates on the characteristics of the intestinal flora in patients with HUA/gout and the effect of the intestinal flora on uric acid metabolism, which will lay a theoretical foundation for the prevention, early diagnosis and auxiliary treatment of HUA/gout. This paper also summarizes recent progress in understanding the impact of different dietary patterns on uric acid levels in order to guide patients to effectively prevent and delay the occurrence of HUA/gout by adjusting their dietary patterns.

Synthetic Aperture Radar (SAR) images are an important data source in microwave vision research; however, computer vision cannot interpret these images effectively based on optical perceptual principles. Therefore, microwave vision, which draws inspiration from human visual perception principles and combines computer vision techniques with electromagnetic physical principles, has become an important research direction in microwave remote sensing. Exploring the cognitive basis for microwave vision is crucial for improving the theoretical system of microwave vision. Therefore, as a preliminary attempt to enhance the theoretical understanding of microwave vision, this paper examines the effectiveness of optical perceptual principles for microwave vision. As a classical visual theory, Gestalt perceptual principles are commonly used for describing the perceptual principles of the human visual system for the external optical world and are a cognitive theoretical foundation of computer vision. In this context, this paper uses SAR images as the research object, focuses on the design process of cognitive psychology experiments, and preliminarily studies the effectiveness of Gestalt perceptual principles for SAR images, including the principles of perceptual grouping and perceptual invariance, exploring the cognitive basis of microwave vision. The experimental results indicate that the Gestalt perceptual principles cannot be directly applied to the algorithm design for SAR images, and the knowledge concepts and visual principles derived from the optical world using the human visual system do not perform well in SAR images. In the future, it will be necessary to summarize the corresponding visual cognitive principles based on the characteristics of microwave images, such as SAR images.

With advances in satellite technology, Polarimetric Synthetic Aperture Radar (PolSAR) now have higher resolution and better data quality, providing excellent data conditions for the refined visual interpretation of artificial targets. The primary method currently used is a multicomponent decomposition, but this method can result in pixel misdivision problems. Thus, we propose a non-fixed threshold division method for achieving advanced feature ship structure characterization in full-polarimetric SAR images. Yamaguchi decomposition can effectively identify the primary scattering mechanism and characterize artificial targets. Its modified volume scattering model is more consistent with actual data. The polarization entropy can serve as the target scattering mechanism at a specified equivalent point in the weakly depolarized state, which can effectively highlight the ship structure. This paper combines the three components of the Yamaguchi decomposition algorithm with the entropy, and divides it into a nine-classification plane with a non-fixed threshold. This method reduces category randomness generated by noise at the threshold boundary for complicated threshold treatments. Furthermore, the Mixed Scattering Mechanism (MSM) which is the region where both secondary scattering and single scattering are significant, was proposed to better match the scattering types of typical structures of vessels in the experiment. The Generalized Similarity Parameter (GSP) was used to further shorten the intra-class distance and perform iterative clustering using a modified GSP-Wishart classifier. This method improves the vessel distinguishability by enhancing the secondary and mixed scattering mechanisms. Finally, this paper uses full-polarimetric SAR data from a port in Shanghai, China, for the experiment. We collected and filtered ship information and optical data from this port through the Automatic Identification System (AIS) and matched them with the ships in full-polarimetric SAR images to verify the correct characterization of each vessel’s features. The experimental results show that the proposed method can effectively distinguish three types of vessels: bulk carriers, container ships and tankers.

Finally, several challenges and potential research prospects are discussed.

Since its inception by Dr. Kabat-Zinn, Mindfulness-Based Stress Reduction (MBSR) has led to various mindfulness interventions and gained positive feedback in many fields. This paper extracts the shared mindfulness mechanisms emphasized by Kabat-Zinn’s MBSR and the Buddhist “Four Foundations of Mindfulness,” assesses their applicability to mindfulness education, and compares their differences in objectives and skills, serving as a reference for the future development of mindfulness education in Taiwan. The study finds that mindfulness education in Taiwan mainly follows Kabat-Zinn’s guidance, focusing on basic practices of “body, feelings, and mind,” with less involvement in higher-level psychological insights. In the aspect of “dharmas,” Kabat-Zinn incorporated Zen concepts, a practice that has seen limited attention and utilization in Taiwan, which also rarely addresses goal-oriented elements. This paper suggests that mindfulness education in Taiwan should emphasize the guidance of “impermanence and non-self” and the systematic thinking of “dharmas,” striving to present these concepts in accessible language to mitigate concerns over religiosity. To enhance mindfulness education in Taiwan, two key areas should be addressed: first, the scope of mindfulness research and practice should expand to include “higher-level psychological qualities”; second, government authorities should consolidate resources to establish a mindfulness research and teacher training center, aiming to develop a comprehensive and practical pedagogical framework. Only with solid academic research and institutional support can mindfulness education in Taiwan be truly strengthened, thereby enhancing public well-being and promoting holistic development.

In the 1920s, the statistician Ronald Fisher introduced a statistical theory system based on probability calculations and evaluations. Fisher coined the term “p-value” to denote the probability of observing the obtained results, assuming that the independent variable is not influenced or manipulated. This calculation helps evaluate the likelihood of such results within the research context. Later, Neyman and Pearson proposed the concepts of null hypothesis and alternative hypothesis, advocating for the inclusion of both in the hypothesis testing. While the two approaches to testing statistical hypotheses were different, these approaches were later integrated into what is now known as null hypothesis significance testing, with the p-value as a standardized measure for statistical analysis. In recent years, however, the academic community has identified a concerning trend known as “p-hacking,” where researchers misuse or abuse data analysis to achieve misleading statistical significance. Then, researchers claim to have speciously successful experiments and publish the implausible research results in journals. This paper focuses on p-hacking within quantitative educational research, exploring its origins, definition, technique, impact, and how journals prevent the manipulation of p-hacking. Finally, this paper reinstates the correct perception of p-value with recommendations for preventing p-hacking, including providing evidence of practical significance while presenting statistical significance, ensuring replicability of research results, stating the structure and details of statistical analysis, and judicious selection of appropriate analytical techniques.

Silicon carbide (SiC) is an important material for shielding nuclear fission products in tri-structural isotropic (TRISO) particles for high-temperature gas-cooled reactors. It has an important influence on the safety performance of TRISO particles. Therefore, it is necessary to study the irradiation behaviors and mechanical properties of the SiC layer of TRISO particles. The irradiation process and nanoindentation process can be described accurately by molecular dynamics simulations. It is helpful to analyze the irradiation behavior and mechanical properties of materials. In this paper, molecular dynamics simulations were used to study the irradiation behavior of equiaxed polycrystalline and long-axis polycrystalline SiC layers obtained from experiments. The calculated theoretical values of the irradiation swelling degree and mechanical properties of the SiC layer are in good agreement with the experimental values. It shows the strong applicability of the potential functions and other simulation system parameters used in this paper. The irradiation behavior of the SiC layer was studied in detail by swelling degree, density, atomic structure type, and point defect evolution. The results show that the grain structure of the SiC layer has no significant effect on its irradiation swelling and amorphization. The amorphization is not directly converted from the crystal structure to the amorphous structure during the irradiation process. The crystal structure is converted into an intermediate state structure and then converted into an amorphous structure. The point defects are mainly C vacancies, Si interstitial atoms, and C antisite atoms in the early stage of irradiation. The difference between the ratio of C point defects and Si point defects gradually disappears after the irradiation dose tends to be saturated. The evolution of amorphization and point defects tends to start nearby the grain boundaries. Irradiation reduces the mechanical properties of SiC layers. It no longer has a significant effect on the mechanical properties of the SiC layer after the irradiation dose tends to be saturated. The changes in the mechanical properties of the SiC layer before and after irradiation were analyzed by load-depth curve and stress & strain. The results show that the decrease in mechanical properties of the SiC layer is closely related to the mechanical behaviors under external force. For example, the bearing capacity and plastic deformation degree decrease, and the stress & strain distribution are disordered. The results provide a quantitative explanation for the irradiation behavior of the SiC layer of TRISO particles and the change of mechanical properties under irradiation. It is helpful to understand the irradiation behavior and relationship between the irradiation behavior and mechanical properties of the SiC layer.

The mathematical model of a radio frequency (RF) system incorporates crucial characteristic parameters of an RF cavity, including the cavity bandwidth, the resonant frequency, and Lorentz force detuning factors, which is very important for the cavity performance evaluation, the control system simulation, and the optimization of low-level control algorithms. A network analyzer is usually used to measure scattering parameters and subsequently construct mathematical models of a RF system. However, the measurement steps are tedious and fail to identify the system model online. Therefore, an advanced online identification algorithm was described for RF cavity systems in this paper, which simulated the operational principles of a network analyzer. This algorithm was integrated within a digital low-level RF (LLRF) system and consisted of a high-precision numerically controlled oscillator, a frequency control word generator module, an amplitude-phase calculation module, and a sweep frequency amplitude-phase processing module. With the assistance of the Matlab/Simulink platform, which provides an ideal environment for simulation and analysis, the deployment of this algorithm was ultimately realized on the field-programmable gate array (FPGA) chip of the low-level system, accomplishing the online identification of RF systems. Then, the sweeping algorithm was verified on a superconducting cavity of the China Accelerator Driven System Front-end Demo Linac at the Institute of Modern Physics. During the verification process, the half-bandwidth of all cavities in CM1 was accurately measured using an online identification algorithm, and the half-bandwidth of all cavities corresponding to CM1 was also measured utilizing a network analyzer. The results of half-bandwidth measured by the two methods are in good agreement, strongly supporting the validity of the online identification algorithm for cavity system models proposed in this paper. Furthermore, we successfully measured the distortion curve of cavity frequency response caused by Lorentz force detuning. Finally, the influence of Lorentz force detuning variation on the measurement of the critical cavity parameters was discussed in this paper. As the RF peak electric field increases, the radiation pressure within the cavity rises proportionately, leading to a corresponding increase in Lorenz force detuning. This article demonstrates that when the RF peak electric field of the cavity operating is less than 16 MV/m, Lorenz force detuning has a relatively limited impact on the bandwidth measurement of the cavity. Conversely, once the peak acceleration electric field surpasses this threshold, Lorenz force detuning exerts an unnegligible effect on the measurement of the half-bandwidth of the cavity. The specific mechanisms of the Lorenz force detuning’s influence on the half-bandwidth of the cavity will be further studied in future research.
