title: Ray Tracing-Based Delay Model for Compensating Gravitational Deformations of VLBI Radio Telescopes (Data Set)

description: The precision and the reliability of very long baseline interferometry (VLBI) depend on several factors. Apart from fabrication discrepancies or meteorological effects, gravity-induced deformations of the receiving unit of VLBI radio telescopes are identified as a crucial error source biasing VLBI products and obtained results such as the scale of a realized global geodetic reference frame. Gravity-induced deformations are systematical errors and yield signal path variations (SPVs). In 1988, Clark and Thomsen derived a VLBI delay model, which was adopted by the International VLBI Service for Geodesy and Astrometry (IVS) to reduce these systematic errors. However, the model parametrizes the SPV by a linear substitute function and considers only deformations acting rotationally symmetrically. The aim of this investigation is to derive the signal path variations of a legacy radio telescope and a modern broadband VGOS-specified radio telescope and to study the effect of nonrotationally symmetric deformation patterns. For that purpose, SPVs are obtained from a nonlinear spatial ray tracing approach. For the first time, a tilt and a displacement of the subreflector perpendicular to the optical axis of the feed unit is taken into account. The results prove the commonly used VLBI delay model as a suitable first-order delay model to reduce gravity-induced deformations.
description: The data files define the incommings of the adjustment process, which were used to derive the signal path variation (SPV) of the 20 m VLBI Radio Telescope Wettzell (RTW) as well as the SPV of the southern 13.2 m Twin Telescope Wettzell (TTW-2).

title: Dataset for a Feasibility Study for Accelerated Reference Point Determination Using Close Range Photogrammetry

description: The Global Geodetic Observing System (GGOS) aims for an accuracy of 1 mm in position concerning a global geodetic reference frame such as the International Terrestrial Reference Frame (ITRF). To derive a global frame, several space geodetic techniques are combined. The combination procedure requires the geometric relations between the invariant reference points of these techniques, the so-called local tie vectors. Each space geodetic technique defines its reference point individually, so the determination of the position of the reference point varies significantly between techniques. Within the international GeoMetre project, measurement systems and analysis strategies are developed to improve the quality of local tie vectors and, thus, the quality of the resulting global frame. The use of close range photogrammetry to determine the reference point of a telescope used for Satellite Laser Ranging (SLR) at the GGOS core station Wettzell in September 2020 is considered as a milestone in this project. This contribution deals with a novel approach for an accelerated reference point determination using close range photogrammetry. In comparison to the conventional photogrammetric approach, published so far, this new approach leads to a significant reduction in recording time. However, in case of inappropriate measurement configuration the approach also bears the risk of biased results. Most importantly, the new approach has the potential to be automated, which is one of the primary calls of GGOS for reference point determinations.

title: Supplementary Material for: Dietary Folate, Vitamin B6 and Vitamin B12 and Risk of Cardiovascular Diseases among Individuals with Type 2 Diabetes: a Case-Control Study

description: Background: Emerging evidence suggests that dietary one-carbon metabolism-related B-vitamins are associated with the reduced risk of cardiovascular disease (CVD) in general populations. However, only a few studies have assessed their associations in patients with type 2 diabetes (T2D). Objective: This study aims to assess the associations between the intake of three one-carbon metabolism-related B-vitamins (folate, vitamin B6 and vitamin B12) and CVD risk in Chinese patients with T2D. Methods: A hospital-based case–control study of 419 patients with T2D and newly diagnosed CVD and 419 age- (±5 years) and sex-matched T2D-only controls was carried out in China. A validated 79-item semiquantitative food-frequency questionnaire administered in face-to-face interviews was used to measure dietary B-vitamin intake. Conditional logistic regression was used to assess associations, which were tested by estimating odds ratios (ORs) with 95% confidence intervals (CIs). Results: Compared with the lowest quartile, the multivariable-adjusted ORs and 95% CIs for highest quartile were 0.32 (95% CI 0.20, 0.52; P-trend &lt; 0.001) for folate, 0.47 (95% CI 0.30, 0.76; P-trend = 0.002) for vitamin B6 and 1.02 (95% CI 0.67, 1.55; P-trend = 0.841) for vitamin B12. Consistent inverse associations were found for folate intake from eggs, vegetables, fruits, soy and other foods but not for folate intake from grains. Conclusions: Findings suggest that the high consumption of folate and vitamin B6, but not that of vitamin B12, might be associated with the low risk of CVD in patients with T2D. This study suggests that dietary folate and vitamin B6 protect against CVD in patients with T2D.

title: Supplementary Material for: Glucocorticoid receptor expression pattern in very low-birth weight infants changes drastically within the first week of life

description: Introduction We herein examined changes in expression levels of the glucocorticoid receptor subtypes GRα and GRβ in very low-birth weight (VLBW) and term infants to clarify time-dependent changes in glucocorticoid sensitivity after birth. Methods Whole blood samples were collected at birth and on postnatal days 4 to 7, and the mRNA expression levels of GRα and GRβ were measured using RT-qPCR. The relative gene expression levels of GRα and GRβ as the target genes normalized to actin beta as the endogenous control were calculated by the comparative cycle threshold method. Results The GRα/GRβ expression ratio at birth was significantly lower in 32 VLBW cesarean section (CS) infants than in term planned CS infants (median (IQR), 1.5 (1.1-1.8)- and 1.1 (0.7-1.6)-fold change, p &lt;0.05). Furthermore, the GRα/GRβ expression ratio increased from day 0 to days 4 to 7 (1.0 (0.6-1.4)- and 1.7 (0.6-1.4)-fold change, p &lt;0.01) in 43 VLBW infants. Discussion / Conclusion The present results suggests that glucocorticoid sensitivity in VLBW infants increases after birth and this rapid change may play a role in surviving critical postnatal events.

title: Dataset for A Modified Approach for Process-Integrated Reference Point Determination

description: The Global Geodetic Observing System (GGOS) calls for continues and automated determination of the geometric reference points of space-geodetic techniques such as DORIS, GNSS, SLR and VLBI. Whereas the reference points of DORIS beacons and GNSS antennas can simply be measured by observing well-defined reference markers, the determination of SLR and VLBI reference points are a metrological challenge, because these reference points are inaccessible and non-materialized. Indirect methods are needed to estimate the reference points in a rigorous way, which fulfil the requirements on an automated and continues reference point determination of the Global Geodetic Observing System. In this investigation, a modified approach for reference point determination of SLR and VLBI telescopes is presented. The results of the new approach are compared to proven reference point models. The numerical deviations of the estimated reference point coordinates and the axis-offset are &lt;&lt;50 μm and demonstrate the equivalence of the new approach.
