Frozen spatial chaos induced by boundaries [PDF]

open access: yes, 1999
We show that rather simple but non-trivial boundary conditions could induce the appearance of spatial chaos (that is stationary, stable, but spatially disordered configurations) in extended dynamical systems with very simple dynamics.

When Viruses Talk through Extracellular Vesicles: a New Perspective on Sars‐Cov‐2‐Induced Neurodegeneration

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT SARS‐CoV‐2 infection is linked to persistent neurological symptoms Post‐Acute Sequelae SARS‐CoV‐2 (neuro‐PASC) and elevated risk of neurodegenerative disease, but molecular events connecting acute viral injury to long‐term CNS dysfunction remain unclear.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Ecological corridors in spatial planning: lessons from over 10 years of contract-based experiences in the French Alps [PDF]

open access: yesSciences, Eaux & Territoires, 2021
Ten years after the introduction of laws resulting from a national consultative process (Grenelle de l'Environnement) in which ecological connectivity was strongly promoted, what can we say about the creation of “corridors” as a new element in spatial ...

From Soil Threats to Soil Health: Prevention or Remediation

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
Conceptual diagram representing the approach for assessing and combining soil threats and health. ABSTRACT While soil threats and soil health are two interrelated, sometimes confused, concepts, we demonstrated here that a clear separation between these two concepts associated to a mapping of both soil threats and soil health is necessary.

Chaos induced coherence in two independent food chains

open access: yes, 2005
Coherence evolution of two food web models can be obtained under the stirring effect of chaotic advection. Each food web model sustains a three--level trophic system composed of interacting predators, consumers and vegetation.

Impact of the drought on the fodder self-sufficiency of organic and conventional highland dairy farms [PDF]

open access: yes, 2008
Eight highland dairy farms in the French Massif Central (4 organic and 4 conventional) were surveyed from 2000 to 2005 to understand the forage system functioning and the specificities of organic farms. During this period two important droughts occurred,
