Mapping the scientific research on maize or corn: a bibliometric analysis of top papers during 2008–2018

Based on the Essential Science Indicators (ESI) database, this study analyzed 966 top papers of maize and corn research from 2008 to 2018, which include 964 highly cited papers and 15 hot papers in the field. Results showed that all papers written in English, were from 4,353 authors, 1,287 organizations and 84 countries/territories, listed in 290 core journals. Top 5 core journals with higher impact factor ranked as Plant Physiology, PNAS, Plant Cell, Food Chemistry and Bioresource Technology. Top six countries and regions were USA, Peoples R China, Germany, France, Australia, England. Top 5 organizations were Cornell Univ, Chinese Acad Sci, Univ Minnesota, Iowa State Univ, Univ Wisconsin. Based on the analysis of network map of VOSviewer, was highlighted cooperation for authors, organizations and countries or regions. The analysis of all keywords showed that maize or corn research was separated six clusters. In addition, this study demonstrates that there are more top papers come from journals with the higher IF and higher rank in WoS Category. So, authors can choose their ideal journal with a high impact factor or Q1 in Category to publish their papers in the English language related to their research field

Gravitational resonances on f(R)f(R)-brane

In this paper, we investigate various $f(R)$-brane models and compare their gravitational resonance structures with the corresponding general relativity (GR)-branes. {Starting from some known GR-brane solutions}, we derive thick $f(R)$-brane solutions such that the metric, scalar field, and scalar potential coincide with those of the corresponding GR-branes. {We find that for branes generated by a single or several canonical scalar fields, there is no obvious distinction between the GR-branes and corresponding $f(R)$-branes in terms of gravitational resonance structure.} Then we discuss the branes generated by K-fields. In this case, there could exist huge differences between GR-branes and $f(R)$-branes.Comment: 17 pages, 14 figures, published versio

Mapping of the world rice research: A bibliometric analysis of top papers during 2008–2018

Based on the Essential Science Indicators database, this study analyzed 1225 top papers of rice research from 2008 to 2018, which include 1219 highly cited papers and 24 hot papers in the field. VOSviewer software was used to visually analyze documents. Results showed that 5100 authors belonging to 1428 organizations from 84 countries/territories authored the papers in 277 core journals. There are 10 papers that have received more than 1000 citations. Top five core journals are Plant Cell, Plant Physiology, PNAS, Food Chemistry and Journal of Experimental Botany. Top 5 countries and regions were China, USA, Japan, England and Germany. Top 5 organizations identified are Chinese Academy of Science, Chinese Academy of Agricultural Science, Huazhong Agricultual University, Nanjing Agricultural University and Zhejiang Univ

Mapping of top papers in the subject category of Water Resources based on the Essential Science Indicators

90-102Based on the Essential Science Indicators (ESI) database, this study analyzed 798 top papers in the subject category of Water Resources from 2008 to 2018. The 798 top papers include 797 highly cited papers and 21 hot papers in the field. Distributions of document type, language of publication, scientific output, and publication of journals are reported in this article. Co-authorship network visualization of author, organizations and countries, co-occurrence network visualization of all keywords was visualized using VOS viewer software. Results showed that 798 papers, all written in English, were from 2,845 authors, 80 countries/territories and 1,107 organizations, listed in 49 journals in the field of water resources. Top 5 core journals with higher impact factor ranked as Water Research, Journal of Hydrology, Desalination, Catena and Advances in Water Resources. Top 5 countries and regions were USA, China, Australia, England and Germany. Top 5 organizations were Chinese Academy of Sciences, University of California System, Helmholtz Association, Delft University of Technology and Eth Zurich. Based on the analysis of network map of VOSviewer, there is cooperation for authors, organizations and countries or regions. The analysis of keywords showed that the research of water resource was separated 6 clusters. This study demonstrates that there are more top papers come from journals with the higher IF and higher rank in Category of Water Resources. Therefore, authors can choose their ideal Journal with a high impact factor to publish papers in the English language related to this research field
