On seasonal trunk thermal buffering and its electrical signature in mature trees
Jean-Baptiste Boulé, Vincent Courtillot, Dominique Gibert +4
Tree trunks contain living tissues whose functioning depends on their thermal environment, yet the processes governing trunk temperature under field conditions remain poorly unders…
On the evolution of the concept of probability as a mirror of the evolution of reason
Jean-Louis Le Mouël, Vincent Courtillot, Dominique Gibert +6
Over the centuries, probability theory has grown from the calculus of games of chance into a central framework for reasoning under uncertainty. This article interprets that evoluti…
On the weak synchronization of a nonlinear solar dynamo oscillator by coherent planetary timing
Jean-Louis Le Mouël, Vincent Courtillot, Vladimir Kossobokov +4
The solar cycle is commonly interpreted as an internally generated magnetic oscillation, yet its phase stability and long-term amplitude modulation remain difficult to explain thro…
On a planetary forcing of global seismicity
Stéphanie Dumont, Jean de Bremond d'Ars, Jean-Baptiste Boulé +10
We have explored the temporal variability of the seismicity at global scale over the last 124 years, as well as its potential drivers. To achieve this, we constructed and analyzed…
On the Optimization of Singular Spectrum Analyses: A Pragmatic Approach
Fernando Lopes, Dominique Gibert, Vincent Courtillot +2
Singular Spectrum Analysis (SSA) occupies a prominent place in the real signal analysis toolkit alongside Fourier and Wavelet analysis. In addition to the two aforementioned analys…
On the mechanism of thermal self-regulation of trees: a kind of homeothermic observation
Jean-Baptiste Boulé, Jean de Bremond d'Ars, Vincent Courtillot +6
What is certain is that surface temperatures around the globe vary considerably, regardless of the time scales or underlying causes. Since 1850, we have observed an average increas…
Information theory, Signal Analysis and Inverse Problem
Dominique Gibert, Fernando Lopes, Vincent Courtillot +2
This book is intended for teaching Signal Analysis methods and Inverse Problems theory. It is completely open access and will remain free. It is currently illustrated with examples…
On the effect of the luni-solar gravitational attraction on trees
Jean-Louis Le Mouël, Dominique Gibert, Jean-Baptiste Boulé +5
In this paper, we revisit old electrical measurements conducted on a poplar tree in 2003 (Gibert et al. 2006), which showed the presence of a diurnal electrical signal, attributed…
On the tilt of the Earth's polar axis (climat): Some 'impressionist' remarks
V. Courtillot, F. Lopes, V. Kossobokov +4
In this lengthy letter, we wanted to discuss the concept of climate based on definitions established for over a century and direct observations that we have been collecting for mor…
A living forest of Tibetan Juniper trees as a new kind of astronomical and geophysical observatory
Vincent Courtillot, Jean-Baptiste Boulé, Jean-Louis Le Mouël +5
The trajectory of Earth about the Sun is perturbed by torques exerted by the Moon and Sun, and also the four giant planets. These provoke variations of insolation at Earth surface,…
On variations of global mean surface temperature: When Laplace meets Milankovic
V. Courtillot, F. Lopes, D. Gibert +2
In his mathematical theory, Milankovic finds a link between the heat received by the Earth surface per unit time as a function of the solar ephemerids and derives a model of climat…
