Current Status of the EU-VGOS Project

The EU-VGOS project began in 2018 with\ua0the aim of using the VGOS infrastructure in Europe\ua0to investigate methods for VGOS data processing. The\ua0project is now structured into Working Groups dealing\ua0with operations (stations), e-transfer, correlation and\ua0post-processing, and analysis. This is a report on the\ua0status of the project

Homocysteine and Coronary Heart Disease: Meta-analysis of MTHFR Case-Control Studies, Avoiding Publication Bias

Robert Clarke and colleagues conduct a meta-analysis of unpublished datasets to examine the causal relationship between elevation of homocysteine levels in the blood and the risk of coronary heart disease. Their data suggest that an increase in homocysteine levels is not likely to result in an increase in risk of coronary heart disease

Zonal Love and Shida numbers estimated by VLBI

The deformation of the anelastic Earth as aresponse to external forces from the Moon and Sun ischaracterized with proportionality parameters, the so-called Love and Shida numbers. The increasing pre-cision and quality of the VLBI (Very Long BaselineInterferometry) measurements allow determining thoseparameters. In particular, the long history of the VLBIdata enables the estimation of Love and Shida numbersat the low frequencies with the longest period of a tidalwave at 18.6 years. In this study we analyze 27 yearsof VLBI measurements (1984.0 - 2011.0) following therecent IERS Conventions 2010. In several global solu-tions, we estimate the complex Love and Shida num-bers of the solid Earth tides for the main long-periodtidal waves. Furthermore, we determine the Love andShida numbers of the rotational deformation due to po-lar motion, the so-called pole tide
