EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

Global Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

Secular evolution of asteroid families: the role of Ceres

, 2015
We consider the role of the dwarf planet Ceres on the secular dynamics of the asteroid main belt. Specifically, we examine the post impact evolution of asteroid families due to the interaction of their members with the linear nodal secular resonance with

Thermochemical equilibrium calculations of high-temperature O2 generation on the early Earth: Giant asteroid impact on land [PDF]

Journal of the Serbian Chemical Society, 2003
Earth’s atmosphere is composed primarily of N2 and O2. The origin of free O2 in the early Earth’s atmosphere is still subject of considerable debate.1 Theoretical models suggest that the initial form of free O2 in the atmosphere has been oceanic H2O ...

Projective Displacement Mapping for Ray Traced Editable Surfaces

Computer Graphics Forum, EarlyView.
Abstract Displacement mapping is an important tool for modeling detailed geometric features. We explore the problem of authoring complex surfaces while ray tracing interactively. Current techniques for ray tracing displaced surfaces rely on acceleration structures that require dynamic rebuilding when edited.

Erosive Hit-and-Run Impact Events: Debris Unbound

, 2015
Erosive collisions among planetary embryos in the inner solar system can lead to multiple remnant bodies, varied in mass, composition and residual velocity. Some of the smaller, unbound debris may become available to seed the main asteroid belt.

Historical Biogeography of Spiny Lobsters in the Genus Panulirus (Achelata: Palinuridae)

Journal of Biogeography, EarlyView.
ABSTRACT Aim Panulirus is the spiny lobster genus with the most living species, containing 22 recognised species split into two lineages distinguished by habitat preference. Diversification has been proposed to occur due to geographic events affecting the distribution of adults and the dispersal potential of long‐lived larvae by oceanic currents ...
