Quality sample collection, handling, and preservation for an effective microbial forensics program
(American Society for Microbiology, 2006-10)
Gold nanorods grown from HgTe nanoparticles directly on various surfaces
(AIP Publishing, 2006-07-14)
Gold nanorods (NRs) are nucleated by HgTe semiconductor nanoparticles. Growth of ~200 X 50 nm2 NRs directly on various surfaces is achieved by using an intermediary polyelectrolyte layer. X-ray photoelectron spectroscopy ...
Inquiry-based exercise for demonstrating prey preference in snakes
(University of California Press, 2006-04)
Towards the Heisenberg limit in magnetometry with parametric down-converted photons
(American Physical Society, 2006-11-16)
Recent theoretical and experimental papers have shown how one can achieve Heisenberg-limited measurements by using entangled photons. Here we show how the photons in a noncollinear down-conversion process can be used for ...
Two-photon excitation dynamics in bound two-body Coulomb systems including ac Stark shift and ionization
(American Physical Society, 2006-05-03)
One of the dominant systematic effects that shift resonance lines in high-precision measurements of twophoton transitions is the dynamic (ac) Stark shift. For suitable laser frequencies, the ac Stark shift acquires an ...
Entanglement by linear SU(2) transformations: Generation and evolution of quantum vortex states
(IOP Publishing, 2006-07-31)
We consider the evolution of a two-mode system of bosons under the action of a Hamiltonian that generates linear SU(2) transformations. The Hamiltonian is generic in that it represents a host of entanglement mechanisms, ...
Entangling pairs of nano-cantilevers, Cooper-pair boxes and mesoscopic teleportation
(IOP Publishing, 2006-03-07)
We propose two schemes to establish entanglement between two mesoscopic quantum systems through a third mesoscopic quantum system. The first scheme entangles two nano-mechanical oscillators in a non-Gaussian entangled state ...
Effect of an organic pesticide on mortality and learning in Africanized honey bees (Apis mellifera L.) in Brasil
(Science Publications, 2006)
Seven experiments were conducted. First, the influence of the consumption of different concentrations of the organic pesticide Bioganic® on mortality was assessed at 11 different time intervals in Africanized honey bees ...
Interferences in parametric interactions driven by quantized fields
(American Physical Society, 2006-07-11)
We report interferences in the quantum fluctuations of the output of a parametric amplifier when the cavity is driven by a quantized field at the signal frequency. The interferences depend on the phase fluctuations of the ...
