Electric currents induced by twisted light in quantum rings
(Optical Society of America, 2009-10)
We theoretically investigate the generation of electric currents in quantum rings resulting from the optical excitation with twisted light. Our model describes the kinetics of electrons in a two-band model of a semiconductor-based ...
The role of Mab as a source for the mu ring of Uranus (Research Note)
(Edp Sciences S A, 2012-07-01)
Context. We previously analysed how the solar radiation force combined with the planetary oblateness changes the orbital evolution of a sample of dust particles located at the secondary ring system of Uranus. Both effects ...
Constructions of codes through the semigroup ring B[X; 1/2(2)Z(0)] and encoding
(Pergamon-Elsevier B.V. Ltd, 2011-08-01)
For any finite commutative ring B with an identity there is a strict inclusion B[X; Z(0)] subset of B[X; Z(0)] subset of B[X; 1/2(2)Z(0)] of commutative semigroup rings. This work is a continuation of Shah et al. (2011) ...
On the location of the ring around the dwarf planet Haumea
(2019-04-11)
The recently discovered ring around the dwarf planet (136108) Haumea is located near the 1:3 resonance between the orbital motion of the ring particles and the spin of Haumea. In the current work, we study the dynamics of ...
Iodine(III)-promoted ring expansion of 1-vinylcycloalkanol derivatives: A metal-free approach toward seven-membered rings
(AMER CHEMICAL SOC, 2008)
A versatile and metal-free approach for the synthesis of molecules bearing seven- and eight-membered rings is described. The strategy is based on the ring expansion of 1-vinylcycloalkanols (or the corresponding silyl or ...
Analytical calculation of blocking probabilities in WDM rings with the first-fit algorithm

Orbital evolution of the mu and nu dust ring particles of Uranus
(Edp Sciences S A, 2009-10-01)
The mu and nu rings of Uranus form a secondary ring-moon system with the satellites Puck, Mab, Portia, and Rosalind. These rings are tenuous and dominated by micrometric particles, which can be strongly disturbed by ...
