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 ...
Directional growth of polypyrrole and polythiophene wires
(AIP Publishing, 2009-01-23)
This work establishes an innovative electrochemical approach to the template-free growth of conducting polypyrrole and polythiophene wires along predictable interelectrode paths up to 30 um in length. These wires have ...
Dielectric response of soft mode in ferroelectric SrTiO3
(AIP Publishing, 2007-01-16)
The authors report far-infrared dielectric properties of powder form ferroelectric SrTiO3. Terahertz time-domain spectroscopy (TDS) measurement reveals that the low-frequency dielectric response of SrTiO3 is a consequence ...
Vacuum-induced Stark shifts for quantum logic using a collective system in a high-quality dispersive cavity
(American Physical Society, 2005-05-13)
A collective system of atoms in a high-quality cavity can be described by a nonlinear interaction which arises due to the Lamb shift of the energy levels due to the cavity vacuum [Agarwal et al., Phys. Rev. A 56, 2249 ...
Exploitation and destabilization of a warm, freshwater ecosystem through engineered hydrological change
(Ecological Society of America, 2008)
Exploitation of freshwater resources is having catastrophic effects on the ecological dynamics, stability, and quality of those water resources on a global scale, especially in arid and semiarid regions. Lake Kinneret, ...
Characterization of Anaplasma marginale isolated from North American bison
(American Society for Microbiology, 2003-08)
Anaplasma marginale (Rickettsiales: Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Although serologic tests have identified American bison, Bison bison, as ...
Comparison of gene expression signatures of diamide, H2O2 and menadione exposed Aspergillus nidulans cultures - Linking genome-wide transcriptional changes to cellular physiology
(BioMed Central, 2005-12-20)
Background: In addition to their cytotoxic nature, reactive oxygen species (ROS) are also signal molecules in diverse cellular processes in eukaryotic organisms. Linking genome-wide transcriptional changes to cellular ...
Comparison of species richness estimates obtained using nearly complete fragments and simulated pyrosequencing-generated fragments in 16S rRNA gene-based environmental surveys
(American Society for Microbiology, 2009-08)
Pyrosequencing-based 16S rRNA gene surveys are increasingly utilized to study highly diverse bacterial communities, with special emphasis on utilizing the large number of sequences obtained (tens to hundreds of thousands) ...
Feeder cattle price slides
(Western Agricultural Economics Association, 2001-07)
A theoretical model is developed to explain the economics of determining price slides for feeder cattle. The contract is viewed as a dynamic game with continuous strategies where the buyer and seller are the players. The ...
Nonclassicality and decoherence of photon-subtracted squeezed states
(American Physical Society, 2007-03-07)
We discuss nonclassical properties of single-photon subtracted squeezed vacuum states in terms of the sub-Poissonian statistics and the negativity of the Wigner function. We derive a compact expression for the Wigner ...
