A novel wear-resistant magnetic thin film material based on a $Ti_{1-x}Fe_xC_{1-y}$ nanocomposite alloy

open access: yes, 2009
In this study we report on the film growth and characterization of thin (approximately 50 nm thick) Ti-Fe-C films deposited on amorphous quartz.

Formation of pure two-electron triplet states in weakly coupled quantum dots attached to ferromagnetic leads

open access: yes, 2006
Weakly coupled quantum dots in the Pauli spin blockade regime are considered with respect to spin-dependent transport. By attaching one half-metallic and one non-magnetic lead, the Pauli spin blockade if formed by a pure triplet state with spin moment ...

Coherent spin rotations in open driven double quantum dots

open access: yes, 2008
We analyze the charge and spin dynamics in a DC biased double quantum dot driven by crossed DC and AC magnetic fields. In this configuration, spatial delocalization due to inter-dot tunnel competes with intra-dot spin rotations induced by the time ...

Density functional theory study of the electronic structure of fluorite Cu$_{2}$Se

open access: yes, 2012
We have investigated the electronic structure of fluorite Cu$_{2}$Se using density functional theory calculations within the LDA, PBE and AM05 approximations as well as with the non-local hybrid PBE0 and HSE approximations.

Stationary and transient leakage current in the Pauli spin blockade

open access: yes, 2009
We study the effects of cotunneling and a non-uniform Zeeman splitting on the stationary and transient leakage current through a double quantum dot in the Pauli spin blockade regime.

An annotated list of the Lepidoptera of Honduras [PDF]

open access: yes, 2012
A biodiversity inventory of the Lepidoptera of Pico Bonito National Park and vicinity, in the Department of Atlantida of northern Honduras, was initiated in 2009 to obtain baseline data.

DNA secondary structures are associated with recombination in major Plasmodium falciparum variable surface antigen gene families [PDF]

open access: yes, 2013
Many bacterial, viral and parasitic pathogens undergo antigenic variation to counter host immune defense mechanisms. In Plasmodium falciparum, the most lethal of human malaria parasites, switching of var gene expression results in alternating expression ...

As borboletas (Lepidoptera: Papilionoidea e Hesperioidea) do Parque Ecológico João Vasconcelos Sobrinho, Caruaru, Pernambuco, Brasil [PDF]

open access: yes, 2015
Comprising a natural reserve with 359 ha of montane forest inserted on the Brazilian semi-arid, the Parque Ecológico João Vasconcelos Sobrinho (PEJVS), locally known as Brejo dos Cavalos is currently under high anthropogenic pressure.
