Coherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
(2000-08-01)
The atomic tunneling between two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well time-dependent trap was studied. For the slowly varying trap, synchronization of oscillations of the trap with oscillations ...

Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...
Trapping of DNA radicals with the nitrone spin trap 5,5-dimethyl-1-pyrroline N-oxide and genotoxic damage: Recent advances using the immuno-spin trapping technology
(Elsevier Science Inc, 2019-10)
Immuno-spin trapping detection of DNA radicals with the nitrone spin trap 5,5-dimethyl-1-pyrrloine N-oxide (DMPO) has made important contributions towards the understanding of DNA radicalization and genotoxicity at sites ...
Analysis of glass tilting dynamic on doors with singleguided window regulators and the impact of trapping force measuring methods on anti-trapping behavior
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia EletrônicaUTFPR, 2019-09-18)
For the past few decades, the automation of vehicles has been gradually changing the user overall experience when on the road. While some functionalities improve the reliability on several car systems, new security concerns ...
Spin Trapping: An Essential Tool for the Study of Diseases Caused by Oxidative Stress
(Bentham Science Publ, 2015)
Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In ...
THE ENERGY BARRIER FOR ELECTRON TRAPPING IN ALXGA1-XAS
(Akademie Verlag Gmbh, 1993-09-16)
Transient decay of persistent photoconductivity measurements are carried out in samples of different compositions. The capture barrier for electron trapping by DX centers is obtained using a method which employs the ...
Identification of the transition state for fast reactions: The trapping of hydroxyl and methyl radicals by DMPO - A DFT approach
(Elsevier Inc., 2014)
Up to date, attempts to locate the transition state (TS) for the trapping reaction between ̇OH and ̇DMPO have been unsuccessful, and the lack of molecular mechanisms by which ̇OH binds to the spin-trap constitutes a question ...
Coupled Bose-Einstein condensate: Collapse for attractive interaction
(2001-04-01)
The collapse of trapped Boson-Einstein condensate (BEC) of atoms in states 1 and 2 was studied. When the interaction among the atoms in state i was attractive the component i of the condensate experienced collapse. When ...
