The Rotation of the Earth Observed by VLBI

open access: yesActa Geodaetica et Geophysica Hungarica, 1999
The eminent importance of Very Long Baseline Interferometry (VLBI) in geodesy and geophysics is due to its connection with an inertial reference frame formed by compact extragalactic radio sources. VLBI is unique in its ability to monitor without hypotheses all components of Earth orientation.

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Precession of the elastic pendulum on the rotating Earth [PDF]

open access: yesarXiv
We present a numerical solution of the nonlinear differential equation for a pendulum with an elastic string on the rotating Earth, for different values of string stiffness at different geographic latitudes.

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

open access: yesAdvanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications.

The deforming and rotating Earth – A review of the 18th International Symposium on Geodynamics and Earth Tide, Trieste 2016

open access: yesGeodesy and Geodynamics, 2018
The 18th International Symposium on Geodynamics and Earth Tides 2016 covered phenomena that generate temporal variations in geodetic and geophysical observations. In calculating the stress field for Earth tides, the observed geodetic response is used for

Long-Term Earth Magnetosphere Science Orbit via Earth-Moon Resonance Orbit [PDF]

open access: yesarXiv
This article investigates long-term orbits within the Earth's magnetosphere, specifically focusing on orbits where the argument of periapsis is synchronized with changes induced by lunar gravity assists and the Earth's argument of latitude over a complete orbital period in Earth-Moon resonance.

A New Global Theory of the Earth's Dynamics : a Single Cause Can Explain All the Geophysical and Geological Phenomena

open access: yes, 2005
After describing all the contradictions associated with the current Plate Tectonics theory, this paper proposes a model where a single cause can explain all geophysical and geological phenomena.
