Debiased albedo distribution for Near Earth Objects
Icarus, 2020 We extend the most recent orbital and absolute magnitude Near Earth Object (NEO) model (Granvik et al., 2018) to provide a statistical description of NEO geometric albedos. Our model is calibrated on NEOWISE albedo data for the NEO population and reproduces these data very well once a simple model for the NEOWISE observational biases is applied.

Adventures in Near-Earth Object Exploration [PDF]
Science, 2006 Asteroids, because of the hazard they pose to Earth, are compelling targets for robotic and human space exploration. Yet because of their exotic low-gravity environment, simply landing on an asteroid appears to be much more challenging than we had appreciated 5 or 10 years ago.

Near-Earth Objects in the Taurid complex [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 The Taurid complex consists of many substreams and has both comet 2P/Encke and several Near-Earth Objects (NEOs) moving within it. We conduct a new search for associated NEOs, investigate the orbital evolution of any identified NEO and search for meteor showers associated with these NEOs.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Origin and dynamics of Near Earth Objects
Comptes Rendus. Physique, 2005 Abstract The population of Near-Earth Objects (NEOs) evolves on orbits which can cross the orbit of the Earth. Most NEOs come from the asteroid belt via unstable zones associated with powerful or diffusive resonances. Their evolutionary paths and the statistical properties of their dynamics have been determined by massive numerical integrations.

FEBS Letters, EarlyView.Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Internal structure of Near-Earth Objects
Comptes Rendus. Physique, 2005 Abstract For the purposes of mitigation, the internal structure of near-Earth objects (NEOs) remains one of the most important but least understood parameters. From a science point of view, the internal structure is equally intriguing. Knowledge of the internal structure can reveal the collisional history, and in the case of comets, may also reveal ...
