Combination of terrestrial reference frames based on space geodetic techniques in SHAO:methodology and main issues

Based on years of input from the four geodetic techniques （SLR, GPS, VLBI and DORIS）, the strategies of the combination were studied in SHAO to generate a new global terrestrial reference frame as the material realization of the ITRS defined in IERS Conventions. The main input includes the time series of weekly solutions （or fortnightly for SLR 1983-1993） of observational data for satellite techniques and session-wise normal equations for VLBI. The set of estimated unknowns includes 3- dimensional Cartesian coordinates at the reference epoch 2005.0 of the stations distributed globally and their rates as well as the time series of consistent Earth Orientation Parameters （EOPs） at the same epochs as the input. Besides the final solution, namely SOL-2, generated by using all the inputs before 2015.0 obtained from short-term observation processing, another reference solution, namely SOL- 1, was also computed by using the input before 2009.0 based on the same combination of procedures for the purpose of comparison with ITRF2008 and DTRF2008 and for evaluating the effect of the latest six more years of data on the combined results. The estimated accuracy of the x-component and y-component of the SOL- 1 TRF-origin was better than 0.1 mm at epoch 2005.0 and better than 0.3 mm yr- 1 in time evolution, either compared with ITRF2008 or DTRF2008. However, the z-component of the translation parameters from SOL-1 to ITRF2008 and DTRF2008 were 3.4 mm and -1.0 ram, respectively. It seems that the z-component of the SOL-1 TRF-origin was much closer to the one in DTRF2008 than the one in ITRF2008. The translation parameters from SOL-2 to ITRF2014 were 2.2, -1.8 and 0.9 mm in the x-, y- and z-components respectively with rates smaller than 0.4 mmyr-1. Similarly, the scale factor transformed from SOL-1 to DTRF2008 was much smaller than that to ITRF2008. The scale parameter from SOL-2 to ITRF2014 was -0.31 ppb with a rate lower than 0.01 ppb yr-1. The external precision （WRMS） compared with IERS EOP 08 C04 of the combined EOP series was smaller than 0.06 mas for the polar motions, smaller than 0.01 ms for the UT1-UTC and smaller than 0.02 ms for the LODs. The precision of the EOPs in SOL-2 was slightly higher than that of SOL-1.

Current global research landscape on COVID-19 and cancer: Bibliometric and visualization analysis

BACKGROUND Cancer is a severe public health issue that seriously jeopardizes global health.In individuals with coronavirus disease 2019(COVID-19),cancer is considered an independent risk factor for severe illness and increased mortality.AIM To identify research hotspots and prospects,we used bibliometrics to examine the global production of COVID-19 literature published in the field of oncology.METHODS Data on publication output were identified based on the Scopus database between January 1,2020,and June 21,2022.This study used VOSviewer to analyze collaboration networks among countries and assess the terms most often used in the titles and abstracts of retrieved publications to determine research hotspots linked to cancer and COVID-19.The Impact Index Per Article for the top 10 high-cited papers collected from Reference Citation Analysis(RCA)are presented.RESULTS A total of 7015 publications were retrieved from the database.The United States published the greatest number of articles(2025;28.87%),followed by Italy(964;13.74%),the United Kingdom(839;11.96%),and China(538;7.67%).The University of Texas MD Anderson Cancer Center(n=205,2.92%)ranked first,followed by the Memorial Sloan-Kettering Cancer Center(n=176,2.51%).The European Journal of Cancer(n=106,1.51%)ranked first,followed by the Frontiers in Oncology(n=104,1.48%),Cancers(n=102,1.45%),and Pediatric Blood and Cancer(n=95;1.35%).The hot topics were stratified into“cancer care management during the COVID-19 pandemic”;and“COVID-19 vaccines in cancer patients”.CONCLUSION This is the first bibliometric analysis to determine the present state and upcoming hot themes related to cancer and COVID-19 and vice versa using VOSviewer during the early stages of the pandemic.The emergence of hot themes related to cancer and COVID-19 may aid researchers in identifying new research areas in this field.
