On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Advancing Heliophysics and Space Weather Modeling Through Open Science

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

L’ignition des feux de forêt par l’action de la foudre au Portugal de 1996 à 2008

open access: yesTerritorium: Revista Portuguesa de riscos, prevenção e segurança, 2010
Une étude des incendies de forêt causés par la foudre est présentée pour le Portugal, de 1996 à 2008. A l’aide des données de tous les feux de foudre enregistrés sur cette période, une analyse de la répartition spatiale et temporelle, de ces phénomènes ...

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Upzoning the YIMBY rent gap: A transit‐oriented spatial fix

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 3, Autumn / automne 2026.
Abstract This paper takes up the phenomenon of transit‐oriented zoning reform as an urban planning solution to the housing crisis that promises affordability, sustainability, and racial justice. I hypothesize that upzoning near transit creates a vertical rent gap that represents a YIMBY (Yes in My Back Yard) spatial fix, a targeted spatial deregulation

Relation entre taux de couverture du sol et biomasse de résidus de cultures : une simplification prédictive est envisageable

open access: yesCahiers Agricultures, 2019
En système d’agriculture de conservation, les résidus de cultures ne sont plus brassés dans un volume de sol labouré mais maintenus à la surface des sols ou partiellement enfouis.

Marécages, une pollution par essence? Conditions d'une écopoétique des marais et autres zones humides au XXe siècle

open access: yesOrbis Litterarum, Volume 81, Issue 3, Page 271-280, June 2026.
Abstract To expose the pollution of marshes and swamps, whether by hydrocarbons or other contaminants, the French or Francophone author of the twentieth century must first confront a literary tradition that equates stagnant water with a volatile poison and, more broadly, wetlands with toxic environments. In his article “Wetland Gloom and Wetland Glory,”

Spatial Reasoning in Comparative Analyses of Physics Diagrams [PDF]

open access: yes, 2014
Spatial reasoning plays a critical role in STEM problem solving. Physics assessments, for example, are rich in diagrams and pictures, which help people understand concrete physical scenarios and abstract aspects of physical reasoning. In this paper we describe a system that analyzes sketched diagrams to solve qualitative physics problems from a popular

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...
