On the relative abundance of LiH and LiH+ molecules in the early universe: new results from quantum reactions

open access: yes, 2011
The relative efficiencies of the chemical pathways that can lead to the destruction of LiH and LiH+ molecules, conjectured to be present in the primordial gas and to control molecular cooling processes in the gravitational collapse of the post ...

A UV flux constraint on the formation of direct collapse black holes [PDF]

open access: yes, 2014
The ability of metal free gas to cool by molecular hydrogen in primordial halos is strongly associated with the strength of ultraviolet (UV) flux produced by the stellar populations in the first galaxies.

Collisional Quenching at Ultralow Energies: Controlling Efficiency with Internal State Selection

open access: yes, 2007
Calculations have been carried out for the vibrational quenching of excited H$_2$ molecules which collide with Li$^+$ ions at ultralow energies. The dynamics has been treated exactly using the well known quantum coupled-channel expansions over different ...

Testing the bounds on quantum probabilities [PDF]

open access: yes, 2003
Bounds on quantum probabilities and expectation values are derived for experimental setups associated with Bell-type inequalities. In analogy to the classical bounds, the quantum limits are experimentally testable and therefore serve as criteria for the ...

Chemical complexity in astrophysical simulations: optimization and reduction techniques

open access: yes, 2013
Chemistry has a key role in the evolution of the interstellar medium (ISM), so it is highly desirable to follow its evolution in numerical simulations. However, it may easily dominate the computational cost when applied to large systems. In this paper we

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis

open access: yesVeterinary Dermatology, EarlyView.
ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.
