Reduced atmospheres of post-impact worlds
Impacts may have had a significant effect on the atmospheric chemistry of the
early Earth. Reduced phases in the impactor (e.g., metallic iron) can reduce
the planet's H$_2$O inventory to produce massive atmospheres rich in...
Ancient and recent collisions revealed by phosphate minerals in the Chelyabinsk meteorite
Abstract The collision history of asteroids is an important archive of inner Solar System evolution. Evidence for these collisions is brought to Earth by meteorites. However, as meteorites often...

DIAGNOSIS OF ENDOCRINE DISEASE: Congenital hypothyroidism
Congenital hypothyroidism (CH) may be primary, due to a defect affecting the thyroid gland itself, or central, due to impaired thyroid-stimulating hormone (TSH)-mediated stimulation of the thyroid gland as a result of...

A Stress Orientation Analysis Framework for Dislocation Glide in Face-Centred Cubic Metals
Plastic deformation in metals is heavily influenced by the loading direction. Studies have explored its effects on multiple mechanisms by analysing individual dislocations, but there is currently no systematic way of...
Annotating answer-set programs in Lana
While past research in answer-set programming (ASP) mainly focused on theory, ASP solver technology,
and applications, the present work situates itself in the context of a quite recent research trend:
