Constraining the Kinematics of the Victoria Microplate and the Northern Western Branch of the East African Rift System

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The fragmentation of continents results in microplates that rotate to accommodate the lateral propagation of bounding rifts. Yet, the relationships between microplate rotation rates, fault slip, and kinematics at propagating rift tips remain unknown.

Volcano‐Tectonic Crisis of Mayotte (2018–2022): A Deformation Model for Geodetic Applications

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Volcano‐tectonic unrest during the 2018–2022 crisis of Mayotte (Comoros archipelago) generated an island‐wide surface displacement reaching ∼ ${\sim} $20 cm, with a relative (internal) deformation of the island of ∼ ${\sim} $10 cm. Correcting for these displacements, which exceed the required accuracy of geodetic network reference coordinates,

The relationship of students' classroom behaviour and word reading—The role of on‐task behaviour as a mediator

Journal of Research in Special Educational Needs, Volume 25, Issue 4, Page 812-822, October 2025.
Abstract The aim of the present study is to examine the relationship between students' classroom behaviour and word reading (decoding), considering the role of students' engagement in learning (defined as on‐task behaviour, OTB, as part of the more global ‘behavioural engagement’ sensu Fredricks) as a mediator between behaviour and reading.

External Cues as Transducers of Peripheral Tissue‐Specific Molecular Clocks to Regulate Systemic Circadian Rhythms and Metabolism

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
Tissue‐specific circadian clocks synchronize via diet, intestinal microbiota, and exercise. Time‐restricted feeding extends lifespan through synergistic action of molecular clocks and autophagy, establishing rhythmicity and harmony in hepatic proteasome activity.

GPS surveys in the foreland-foredeep tectonic system of Southeastern Sicily:first results

Annals of Geophysics, 2002
The Hyblean plateau (Southeastern Sicily)is characterised by three main tectonic structural trends: the first, NNW-SSE striking,runs on the eastern most part of the plateau and is linked to the Hyblean-Maltese fault system; the second runs along the ...

From Reference Frames to Relativistic Experiments: Absolute and Relative Radio Astrometry

, 2004
Reference systems and frames are crucial for high precision absolute astrometric work, and their foundations must be well-defined. The current frame, the International Celestial Reference Frame, will be discussed: its history, the use of the group delay ...
