Circadian autophagy drives iTRF-mediated longevity [PDF]
Nature, 2021 Time-restricted feeding (TRF) has recently gained interest as a potential anti-ageing treatment for organisms from Drosophila to humans1-5. TRF restricts food intake to specific hours of the day. Because TRF controls the timing of feeding, rather than nutrient or caloric content, TRF has been hypothesized to depend on circadian-regulated functions; the

International Association of Geodesy Symposia, 2022 Abstract The aim of this paper is to present the results from the GNSS-based densification of the International Terrestrial Reference Frame (ITRF) in the region of Cyprus. The regional network used for this task consists of nine permanent GNSS Cypriot stations (eight stations of the existing CYPOS network plus the NICO station which belongs ...

Past and present ITRF solutions from geophysical perspectives
Advances in Space Research, 2020 Abstract Questions about the accuracy of the origin of the different versions of International Terrestrial Reference Frame (ITRF), have been regularly raised. In particular the origin drift between ITRF2000 and ITRF2005 (and subsequent ITRF solutions) is well-known to be problematic.

A NONLINEAR CONVERSION MODEL FORM ITRFYY TO CGCS2000 [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 At present, ITRS series reference frameworks are widely used in the world. The results of GNSS are mostly based on the ITRF framework. Transform from ITRF to CGCS2000 is not easy, which restricts the promotion and use of CGCS2000.

Maintenance of Millimeter-level Geodetic Reference Framework [PDF]
Journal of Geodesy and Geoinformation Science, 2023 The high-precision terrestrial reference frame, as the spatial benchmark for geodesy, is an important national infrastructure. However, due to the influence of nonlinear factors related to geophysical phenomena, the overall maintenance accuracy of the ...
