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

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 ...

Difalia em um bovino

open access: yesActa Scientiae Veterinariae, 2018
Difalo, penis duplo ou bifido e uma anomalia congenita rara que ocorre em animais e no homem, com escassos relatos na literatura. Este relato apresenta um caso de difalia em um bovino macho adulto castrado. A peca do sistema reprodutor de um bovino foi encaminhada por um frigorifico local para realizacao de exame histologico.

Physiological role of potassium channels in mammalian germ cell differentiation, maturation, and capacitation

open access: yesAndrology, Volume 13, Issue 2, Page 184-201, February 2025.
Abstract Background Ion channels are essential for differentiation and maturation of germ cells, and even for fertilization in mammals. Different types of potassium channels have been identified, which are grouped into voltage‐gated channels (Kv), ligand‐gated channels (Kligand), inwardly rectifying channels (Kir), and tandem pore domain channels (K2P).

Dark-matter halo mergers as a fertile environment for low-mass Population III star formation

open access: yes, 2014
While Population III stars are typically thought to be massive, pathways towards lower-mass Pop III stars may exist when the cooling of the gas is particularly enhanced. A possible route is enhanced HD cooling during the merging of dark-matter halos. The

HUMAN AGENCY IN DIVERSE ECOSYSTEMS: DYNAMICS OF CONTINUITY AND TRANSFORMATION IN SOUTH‐EAST ITALY DURING THE COPPER AND BRONZE AGES

open access: yesOxford Journal of Archaeology, Volume 44, Issue 1, Page 76-100, February 2025.
Summary This paper investigates the changing cultural landscapes of south‐east Italy between the fourth and second millennia BC, a period that saw profound transformations in sociocultural spheres in the Central Mediterranean. It highlights the intertwined cultural and environmental processes that shaped the inhabited landscape during this period ...
