French Meteor Network for High Precision Orbits of Meteoroids [PDF]

open access: yes, 2011
There is a lack of precise meteoroids orbit from video observations as most of the meteor stations use off-the-shelf CCD cameras. Few meteoroids orbit with precise semi-major axis are available using film photographic method. Precise orbits are necessary

The Mediterranean Extreme Events Experiment and storm Harry in January 2026

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This article introduces the Mediterranean Extreme Events Experiment (M3E) – a new project consisting of partners from Europe and the United States – whose main objective is to improve the weather forecasting of extreme events in the Mediterranean region via the deployment of drifting buoys with barometers (shown).

Meteor fluxes and visual magnitudes from EISCAT radar event rates: a comparison with cross-section based magnitude estimates and optical data [PDF]

open access: yesAnnales Geophysicae, 1998
Incoherent scatter radars (ISR) are versatile instruments for continuous monitoring of ionisation processes in the Earth's atmosphere. EISCAT, The European Incoherent Scatter facility has proven effective also in meteor studies. The time resolution of

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

The Spectrum and Orbit of a Fireball Producing Mesospheric Irregularity and Implications for Meteor Mass Deposition

open access: yesThe Astrophysical Journal, 2023
The physical properties of meteoroids producing meteor plasma non-field-aligned irregularities (NFAI) in the Earth’s atmosphere are poorly known. Here we report a complete picture of a fireball and mesospheric NFAI that it produced for the first time ...

Fragmentation and densities of meteoroids [PDF]

open access: yes, 1992
Photographic observations of meteors carried out in Dushanbe by the method of instantaneous exposure have shown clearly that meteoroids entering the Earth's atmosphere are subjected to different types of fragmentation.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

open access: yesStructural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

The Timely Rise of a Teenage Reformer: Youth Revolt, Feminism and the Struggle for a ‘New Sexual Morality’ at the Dawn of the Spanish Second Republic

open access: yesGender &History, EarlyView.
ABSTRACT The contributions of propagandist and writer Hildegart (1914–1933) to Spanish cultural life are overshadowed by accounts of her unusual upbringing and violent death. This article examines the conditions that enabled the teenager to become a prominent voice for feminism and sexual reform on the eve of Spain's Second Republic (1931–1939).

Tracing the main belt origins of S-complex near-Earth objects: From space mission targets to meteorite sources

open access: yesAstronomy & Astrophysics
Context. Space missions to near-Earth objects (NEOs) provide remarkable opportunities to study and characterise their physical and compositional properties in detail. Interpreting these results in a broader context requires knowledge of their provenance,
