The continuous increase in the volume of geospatial data has led to the creation of storage tools and the cloud to process data. Google Earth Engine (GEE) is a cloud-based platform that facilitates geoprocessing, making it a tool of great interest to the academic and research world. This article proposes a bibliometric analysis of the GEE platform to analyze its scientific production. The methodology consists of four phases. The first phase corresponds to selecting "search" criteria, followed by the second phase focused on collecting data during the 2011 and 2022 periods using Elsevier's Scopus database. Software and bibliometrics allowed to review the published articles during the third phase. Finally, the results were analyzed and interpreted in the last phase. The research found 2800 documents that received contributions from 125 countries, with China and the USA leading as the countries with higher contributions supporting an increment in the use of GEE for the visualization and processing of geospatial data. The intellectual structure study and knowledge mapping showed that topics of interest included satellites, sensors, remote sensing, machine learning, land use and land cover. The co-citations analysis revealed the connection between the researchers who used the GEE platform in their research papers. GEE has proven to be an emergent web platform with the potential to manage big satellite data easily. Furthermore, GEE is considered a multidisciplinary tool with multiple applications in various areas of knowledge. This research adds to the current knowledge about the Google Earth Engine platform, analyzing its cognitive structure related to the research in the Scopus database. In addition, this study presents inferences and suggestions to develop future works with this methodology. [ABSTRACT FROM AUTHOR]

Objectives: To summarize development processes and research hotspots of MRI research on acupuncture and to provide new insights for researchers in future studies. Methods: Publications regarding MRI on acupuncture from inception to 2020 were downloaded from the Web of Science Core Collection. VOSviewer 1.6.15 and CiteSpace V software were used for bibliometric analyses. The main analyses include collaboration analyses between countries/institutions/authors, co-occurrence analysis between keywords, as well as analyses on keyword bursts, citation references, and clusters of references. Results: A total of 829 papers were obtained with a continually increased trend over time. The most productive country and institution in this field were the People's Republic of China (475) and KyungHee University (70), respectively. Evidence-based Complementary and Alternative Medicine (83) was the most productive journal, and Neuroimage (454) was the most co-cited journal. Dhond's et al. (2008) article (co-citation counts: 58) and Napadow's et al. (2005) article (centrality: 0.21) were the most representative and symbolic references, with the highest co-citation number and centrality, respectively. Jie Tian had the highest number of publications (35) and Kathleen K S Hui was the most influential author (280 co-citations). The four hot topics in MRI on acupuncture were acupuncture, fMRI, pain, and stimulation. The three frontier topics were connectivity, modulation, and fMRI. Based on the clustering of co-cited documents, chronic low back pain, sham electro-acupuncture treatment, and clinical research were the main research directions. Conclusion: This study provides an in-depth perspective for MRI research on acupuncture and provides researchers with valuable information to determine the current status, hot spots, and frontier trends of MRI research on acupuncture.

The aim of this paper is to visualize the history of evidence-based medicine ( EBM) and to examine the characteristics of EBM development in China and the West. We searched the Web of Science and the Chinese National Knowledge Infrastructure database for papers related to EBM. We applied information visualization techniques, citation analysis, cocitation analysis, cocitation cluster analysis, and network analysis to construct historiographies, themes networks, and chronological theme maps regarding EBM in China and the West. EBM appeared to develop in 4 stages: incubation (1972-1992 in the West vs. 1982-1999 in China), initiation (1992-1993 vs. 1999-2000), rapid development (1993-2000 vs. 2000-2004), and stable distribution (2000 onwards vs. 2004 onwards). Although there was a lag in EBM initiation in China compared with the West, the pace of development appeared similar. Our study shows that important differences exist in research themes, domain structures, and development depth, and in the speed of adoption between China and the West. In the West, efforts in EBM have shifted from education to practice, and from the quality of evidence to its translation. In China, there was a similar shift from education to practice, and from production of evidence to its translation. In addition, this concept has diffused to other healthcare areas, leading to the development of evidence-based traditional Chinese medicine, evidence-based nursing, and evidence-based policy making.

The present study is the first of its kind as it attempts to ascertain the current status of library and information science (LIS) research from the Chinese perspective, by focusing on English research contributions by Chinese LIS scholars. Leading contributors; individual (author) contributors; institutional contributors, and research collaborations were examined. The review comprises 564 articles published in international journals indexed by Social Science Citation Index (SSCI) from 2012-2013. Co-authorship analysis and co-citation analysis were used to draw the results. The results revealed two major findings; first, the Chinese research community is engaged in focusing on cross-national collaboration to establish their existence in international literature and establish colleague relationship with foreigner researchers. USA, UK, and Belgium are the primary counterparts of international collaborative papers. Chinese institutions have eminent professors in the LIS field who incorporate internationaloriented scholarly researches (48.04%) around the globe. Secondly, Chinese researchers have enough knowledge to conduct research, both as single authors (26.24%) and through internal academic collaboration between senior and junior researchers. The Chinese LIS research community has not paid much attention to conducting research on inter-institutional level (7.20%) and on inter-regional level (6.73%). Nevertheless, Wuhan University, City University Hong Kong, and Chinese Academy of Sciences have emerged as the leading institutions in producing LIS publications. Chinese immigrant scholars also have contributed to LIS China's international scientific collaboration. It is a worthwhile and unique study as it examines the collaboration trends networks analysis of international publications by Chinese scholars. [ABSTRACT FROM AUTHOR]

Ground-penetrating radar (GPR) is an established technology with a wide range of applications for civil engineering, geological research, archaeological studies, and hydrological practices.

This study reports the publication trends, sources of publications and subject categories, cooperation of countries, productivity of authors, citations of publications, and clusters of keywords in GPR-related research. The Science Citation Index Expanded (SCI-EXPANDED) and the Social Sciences Citation Index (SSCI), which can be accessed through the Web of Science Core Collection, are used as references. The findings report that the number of publications is 6880 between 2001 and 2021. The number of annual publications has increased significantly, from 139 in 2001 to 576 in 2021. The studies are published in 894 journals, and the annual number of active journals increased from 68 in 2001 to 215 in 2021. Throughout the study, the number of subject categories involved in GPR-related research fluctuated, ranging from 38 in 2001 to 68 in 2021. The research studies originated from 118 countries on 6 continents, where the United States and the People's Republic of China led the research articles. The top five most common keywords are ground-penetrating radar, non-destructive testing, geophysics, electrical resistivity tomography, and radar. After investigating the clusters of keywords, it is determined that civil engineering, geological research, archaeological studies, and hydrological practices are the four main research fields incorporating GPR utilization. This study offers academics and practitioners an in-depth review of the latest research in GPR research as well as a multidisciplinary reference for future studies. [ABSTRACT FROM AUTHOR]

Mercury (Hg) is a global pollutant affecting ecosystems and posing risks to wildlife and human health. Mercury in soil represents a major indicator of its availability to enter both the terrestrial (agriculture) and aquatic food chain (fish and seafood) and contaminate consumers. Therefore, interest in soil Hg concentrations is useful for environmental Hg monitoring and remediation of contamined areas. Thus, we use scientometrics to integrate worldwide studies of Hg in soil that were published between 1991 and 2020. We evaluated (i) how the global dynamics of publications on Hg is determined, (ii) the determining factors for the distribution of research concerning institutions and study topics, and (iii) identified gaps in research. Three main clusters of studies in soil were identified: (1) Hg pollution related to land use and urban soils, highlighting China, and Hg environmental risk to ecological systems; (2) highlight of the Amazon as an important study area, and the bioavailability of Hg in the soil associated with phytoremediation and its methylation; (3) mobilization, speciation, and the relationship of Hg with the content of organic matter in the soil. The main research institutions related to the published research are mainly from China and the USA. Overall, most studies on Hg in soils are done in contaminated places or nearby active sources of Hg pollution. We conclude that scientometric studies of Hg in soils are key in guiding research development and knowledge integration useful to scientists and environmental policies to achieve the goals of the Minamata Convention.
