Background: The global scientific community has been quick to respond to health crisis unleashed by Covid-19 pandemic with intensified investments in R&D and thereby it gave new impetus to Covid-19 research. The world has come to witness unprecedented increase in research publications on control and treatment of Covid-19 pandemic. Like any other region in the world, South Asia too has been the worst-hit region and it too witnessed increase in Covid-related research studies. Systematic reviews of such literature and bibliometric studies are used nowadays as tools to identify and analyze key and significant South Asian contribution to the subject. The present study aims to assess and quantify the contribution and impact of Covid-19 research made by a group of select four South Asian countries. Methods: Publications data on Covid 19 covering the period between December 2019 and 8.7.2021 was sourced from the Scopus database. VOSviewer 1.6.14 software was applied to generate network maps, assess hot topics in the area and describe collaboration patterns in research between different countries. Results: A total of 18,64,275 publications reflecting the global research output on Covid-19 were retrieved from the Scopus database. The publications data of select four South Asian countries - Pakistan, Bangladesh, Nepal and Sri Lanka - was also retrieved. Comparatively the data size of select four South Asian countries was small, limited to 4012 documents, and accounting for a 2.15% share of the global research output on Covid-19 virus. Pakistan published the most number of Covid-19 publications (n = 2246, 55.58%), followed by Bangladesh (n = 1203, 29.99%), Nepal (n=512, 12.76%) and Sri Lanka (n=202, 5.03%). The United States as the collaborating partner in most number of publications contributed by South Asian countries (n = 609, 25.41%), followed by the United Kingdom (n = 496, 20.69%), China (n=453, 18.90%), Saudi Arabia (n=441, 18.40%) and India (n=426, 17.77%). Covid-19 treatment type was the most studied topic in the contributions made by South Asian countries accounting for a 16.45% share, followed by epidemiology (15.63%), risk factors (5.835), clinical studies (4.81%), etc. Conclusion: This paper finds that the quantity and quality of research pursued by a select group of four South Asian countries in the domain of Covid 19 studies has so far been small and insignificant. There is an urgent need on the part of select group of South Asian counties to improve their productivity and qualitative performance at the national, institutional, and individual author level.

The study provides a quantitative and qualitative description of global research in the domain of quantum machine learning (QML) as a way to understand the status of global research in the subject at the global, national, institutional, and individual author level. The data for the study was sourced from the Scopus database for the period 1999-2020. The study analyzed global research output (1374 publications) and global citations (22434 citations) to measure research productivity and performance on metrics. In addition, the study carried out bibliometric mapping of the literature to visually represent network relationship between key countries, institutions, authors, and significant keyword in QML research. The study finds that the USA and China lead the world ranking in QML research, accounting for 32.46% and 22.56% share respectively in the global output. The top 25 global organizations and authors lead with 35.52% and 16.59% global share respectively. The study also tracks key research areas, key global players, most significant keywords, and most productive source journals. The study observes that QML research is gradually emerging as an interdisciplinary area of research in computer science, but the body of its literature that has appeared so far is very small and insignificant even though 22 years have passed since the appearance of its first publication. Certainly, QML as a research subject at present is at a nascent stage of its development. [ABSTRACT FROM AUTHOR]

Objectives: The main objective of this research is to identify highly cited papers in clinical pharmacology and to analyze their publication and citation data to study their citation characteristics, and understand what role contributing authors, participating research organizations as well as international collaborative countries play in Indian clinical pharmacology research. Design: The publications output of Indian clinical pharmacology papers published during 2000-14 were screened in Scopus database and highly cited papers, with at least 100 citations since publication, were identified and shortlisted for their bibliometric analysis. The statistics cover collaboration across authors, institutions, foreign participating countries in the publication of highly cited papers. To assess comparative contributions of authors/organizations, a new indicator, the Major Contributor Index (MCI), was used. Citation trends for all papers, as well as for top papers, are presented. Results: A total of 76 highly cited articles, constituting 1.45% share of world highly cited papers output and 0.75% share of India's publications output, were published by India in clinical pharmacology output during 2000-14. This study covered only those papers that received at least 100 citations since publication. In recent years, top-cited articles have reached their citation peak in the early years of their citation life cycle, but have shown a more-rapid decreasing trend compared to top-cited articles from past decades. These 76 highly articles have received 14059 citations, with an average citation per paper of 184.99. The leading Indian organizations participating in highly cited research papers were All India Institute of Medical Sciences, New Delhi (7 papers), Panjab University, Chandigarh (6 papers), Jadavpur University, Kolkata (5 papers), National Institute of Mental Health & Allied Sciences, Bangalore, Aligarh Muslim University, Annamalai University, Banaras Hindu University, Varanasi, Sathyabama University, Guru Jambeshwar University, Hisar, Post Graduate Institute of Medical Education & Research, Chandigarh, Institute of Life Sciences, Bhubaneswar and Drug Research & Development Center, Kolkata (2 papers each). The leading authors were S.K. Bhattacharya (3 papers), J.K. Grover, S.P. Yadav, S. Garg, A.K. Singla, A.Garg, S. Ghosal, A. Bhattacharya, S. Khanna, A. Bhattacharya, S. Praveen and S.K.Sahoo (2 papers each). The leading international collaborative countries were USA (10 papers), Germany and U.K. (3 papers each), Japan, Russia Federation, Belgium and Canada (2 papers each). The MCI varied among leading organizations, as well as among individual authors. Conclusions: The output of highly cited papers by Indian authors in clinical pharmacology is still not significant given the fact that 208 authors contributed only one paper each once in 15 years, 11 contributed two papers each once in 15 years, and 1 contributed three papers once in 15 years. India still ranks 10th highest country with 1.45% share to the world output of highly cited papers compared to 61.41% share by USA. The quality of research in clinical pharmacology in India is though growing significantly over time, but there is very little evidence of corresponding growth in publication rate of highly cited papers in India.

Six selected state universities of Haryana were inter-compared for their research performance in science & technology, using publications data drawn from SCOPUS database covering the period 2006-15. The status and performance of six selected Haryana state universities in S&T research, as seen from a series of bibliometric indicators, has been found to be weak and far behind the overall performance of India and Haryana state in the university sector. The selected Haryana six universities group registered 6.87% growth, and accounted for 0.81% national share, 31.87% state share, and 10.2% share of international collaborative papers. The six universities group needs to build and improve their academic and research potential significantly in case it aspires to come at par with others in higher education sector in the country. The Haryana state should encourage its universities to participate and contribute aggressively to S&T research, establish globalized environment of higher education as well as reveal competitive nature of their research.
