Application of Phosphine-Phosphite Ligands in the Iridium Catalyzed Enantioselective Hydrogenation of 2-Methylquinoline
(Multidisciplinary Digital Publishing Institute, 2010-10-29)
The hydrogenation of 2-methylquinoline with Ir catalysts based on chiral phosphine-phosphites has been investigated. It has been observed that the reaction is very sensitive to the nature of the ligand. Optimization of the ...

Codificación de los movimientos oculares sacádicos en el mesencéfalo: una aproximación comparada
(2010)
El sistema nervioso motor se organiza de forma jerárquica y modular para codificar el movimiento. El sistema de generación de los movimientos oculares sacádicos permite estudiar los mecanismos de programación y ejecución ...

Environmentally responsive nanoparticle-based luminescent optical resonators
(Royal Society of Chemistry, 2010)
In this work, we demonstrate that optical resonators built using all-nanoparticle-based porous building blocks provide a responsive multifunctional matrix, totally different emission spectra being attained from the same ...

Redes MOBILE MOS-NDR operando con reloj de una fase
(2010)
La existencia de dispositivos con una característica I-V que exhibe una resistencia diferencial negativa (Negative Differential Resistance, NDR) resulta atractiva desde el punto de vista del diseño de circuitos, como ...

Towards a Rewriting Logic Semantics for ATL
(Springer, 2010)
As the complexity of model transformation (MT) grows, the need to count on formal semantics ofMT languages also increases. Firstly, formal semantics provide precise specifications of the expected behavior of transforma ...

Spiking Neural P systems with weights
(MIT Press, 2010)
A variant of spiking neural P systems with positive or negative weights on synapses is introduced, where the rules of a neuron fire when the potential of that neuron equals a given value. The involved values—weights, firing ...

Circuit model for a periodic array of slits sandwiched between two dielectric slabs
(American Institute of Physics, 2010)
This paper proposes an equivalent circuit model that uses lumped elements and transmission lines to explain the transmission of electromagnetic waves through a conducting screen periodically perforated with slits and ...

Simulating Domain Specific Visual Models by Observation
(ACM Digital Library, 2010)
Domain Specific Visual Languages (DSVLs) are essential elements in Model-Driven Engineering (MDE) for representing models and metamodels. In-place model transformations provide an intuitive way to complement metamodels ...

Representing the Surface of Objects by Combinatorial Pyramids
(Czech Pattern Recognition Society, 2010)
This paper introduces a new method to rep- resent the surface of objects using two dimensional com- binatorial maps. The classical de nition of two dimen- sional combinatorial maps is extended here by adding a \back ...

A P-Lingua based simulator for Tissue P systems
(Elsevier, 2010)
Investigations within the field of tissue-like P systems are being conducted, on one hand studying their computational efficiency, and on the other hand exploring the possibilities to use them as a computational modelling ...
