Error assessment of GOCE SGG data using along track interpolation [PDF]
Advances in Geosciences, 2003 GOCE will be the first satellite gravity mission measuring gravity gradients in space using a dedicated instrument called a gradiometer. High resolution gravity field recovery will be possible from these gradients.

PARAMETRIC AMPLIFICATION OF THE SIGNALS IN THE ELECTROSTATIC GRAVIINERTIAL SENSOR
Приборы и методы измерений, 2017 The challenges of designing simple, reliable, and high sensitivity graviinertial sensors are investigated. The sensor comprises a proof mass (PM) and is fixed with the housing by the elastic torsion suspension.

Archaeological Prospection, Volume 32, Issue 3, Page 507-524, July/September 2025.ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

Oscillatory Coupling Between Thalamus, Cerebellum, and Motor Cortex in Essential Tremor
Movement Disorders, Volume 40, Issue 5, Page 896-905, May 2025.Abstract Background Essential tremor is hypothesized to emerge from synchronized oscillatory activity within the cerebello‐thalamo‐cortical circuit. However, this hypothesis has not yet been tested using local field potentials directly recorded from the thalamus alongside signals from both the cortex and cerebellum, leaving a gap in the understanding ...

Advancements in the GRACE and GRACE‐FO Gradiometer Mode
Earth and Space Science, Volume 12, Issue 5, May 2025.Abstract The global gravitational gradient field has not been observed since the decommission of GOCE in 2013. Based on the foundational work of Peidou and Pagiatakis (2019, https://doi.org/10.1029/2018jb016382), we advance the concept of GRACE gradiometer mode (GM) for the purpose of using GRACE, GRACE‐FO and future gravity space missions as ...
